Specifically, first, the biological information detection control unit 202 performs control to detect biological information and the characteristic value calculating unit 203 calculates a characteristic value, i.e., a blood pressure value (e.g., a systolic blood pressure value), based on detected biological information (pulse wave information). Then, data on the calculated blood pressure value (data on the characteristic value) is stored in the exercise result storage unit 126 as blood pressure data Tlbn. Note that at the time of or before detecting biological information, the user may be urged to take a deep breath.
- a blood pressure value e.g., a systolic blood pressure value
- step S 6 a calculation/informing/storage process of an effect index for before each exercise is performed (step S 6 ).
- the effect index calculating unit 204 calculates an effect index, i.e., the degree of decrease in blood pressure value, for before each exercise, based on blood pressure data Tlbn for this time which is calculated and stored in step S 4 and blood pressure data Tlb 1 for the first time.
- Information indicating the calculated degree of decrease in blood pressure value is displayed in a predetermined area of the display unit 4 .
- step S 8 it is determined whether an instruction to start exercise has been inputted. Specifically, it is determined whether the start switch 21 . 3 has been pressed by the user.
- the control unit 20 waits until an input of a start instruction has been detected (NO in step S 8 ). If an input of a start instruction has been detected (YES in step S 8 ), then processing proceeds to step S 10 . Note that although here breathing exercise starts after an instruction from the user has been inputted, breathing exercise may automatically start after an effect index has been informed (after the process in step S 6 ).
- step S 10 the guide unit 201 guides an exercise pattern determined in step S 2 to the user. Specifically, a breathing guide (e.g., how much more exhalation or inhalation should be performed) is displayed on the display unit 4 based on exercise pattern data pointed to by the pointer PN in the execution pattern information storage unit 124 .
- a breathing guide e.g., how much more exhalation or inhalation should be performed
- step S 12 it is determined whether evaluation timing has come (step S 12 ).
- the evaluation timing may be predetermined such as every five minutes, for example, after the start of exercise, or whether it is evaluation timing may be determined by an instruction from the user. If it is determined that evaluation timing has come (YES in step S 12 ), then processing proceeds to step S 14 . On the other hand, if it is determined that evaluation time has not come (NO in step S 12 ), then processing proceeds to step S 18 .

- the processes for biological information detection and characteristic value calculation here can be performed in the same manner as that for step S 4 .
- a calculated characteristic value (data on a blood pressure value) is stored in the exercise result storage unit 126 as blood pressure data Tltn (blood pressure data Tlt′n if it is a second time).
- step S 16 a calculation/informing process of an effect index for during exercise is performed (step S 16 ).
- the effect index calculating unit 204 calculates an effect index, i.e., the degree of decrease in blood pressure value, for during exercise based on, for example, the blood pressure data Tltn and blood pressure data Tlt′n calculated and stored in step S 14 .
- an effect index for during exercise may be calculated based on the blood pressure data Tlbn calculated and stored in step S 4 and the blood pressure data Tltn calculated and stored in step S 14 .
- Information on the calculated degree of decrease in blood pressure value is displayed in a predetermined area of the display unit 4 . By this, the degree of decrease in blood pressure value for during exercise can be informed to the user.
- step S 18 it is determined whether an exercise period has elapsed. If an exercise period has not elapsed (NO in step S 18 ), then processing returns to step S 10 . On the other hand, if it is determined that an exercise period has elapsed (YES in step S 18 ), then processing proceeds to step S 20 .
- step S 20 a biological information detection process and a characteristic value calculation/storage process are further performed.
- the processes for biological information detection and characteristic value calculation here can also be performed in the same manner as that for step S 4 .

- the effect index calculating unit 204 calculates an effect index, i.e., the degree of decrease in blood pressure value, for before and after exercise based on the blood pressure data Tlbn for before exercise which is calculated and stored in step S 4 and the blood pressure data Tlan for after exercise which is calculated and stored in step S 20 .
- Information on the calculated degree of decrease in blood pressure value is displayed in a predetermined area of the display unit 4 . By this, the degree of decrease in blood pressure value for after exercise with reference to a blood pressure value for before exercise can be informed to the user. Furthermore, the calculated degree of decrease in blood pressure value for before and after exercise is stored as effect index data Elban.
- an effect index i.e., the degree of decrease in blood pressure value
- the effect index calculating unit 204 calculates an effect index, i.e., the degree of decrease in blood pressure value, for after each exercise based on the blood pressure data Tlan for this time which is calculated and stored in step S 20 and the blood pressure data Tla 1 for the first time.

- the calculated degree of decrease in blood pressure value for after each exercise is stored as effect index data Elan.
- step S 24 it is determined whether there is a past effect index (an effect index associated with a previous exercise period) (step S 24 ). If it is determined that a past effect index is stored in the exercise result storage unit 126 (YES in step S 24 ), then processing proceeds to step S 26 . On the other hand, if a past effect index is not stored (NO in step S 24 ), then the breathing exercise process ends.
- a past effect index an effect index associated with a previous exercise period
- step S 26 the informing unit 206 displays a trend between the past effect index and the effect index for this time on the display unit 4 . By this, the trend of the effect index is informed to the user.
- the series of breathing exercise process ends.
- FIG. 5 is a flowchart showing the exercise pattern determination process in the first embodiment of the present invention.
- step S 102 the control unit 20 determines whether an exercise pattern is already set. If an exercise pattern is not already set (NO in step S 102 ), then processing proceeds to step S 104 . On the other hand, if an exercise pattern is already set (YES in step S 102 ), then processing proceeds to step S 106 .
- step S 104 the control unit 20 accepts an input of physical information (e.g., age, sex, etc.) from the user and stores the physical information in the storage area 124 A of the execution pattern information storage unit 124 .
- physical information e.g., age, sex, etc.
- step S 105 an exercise pattern setting/storage process is performed based on the accepted physical information. Specifically, for example, a process such as that below is performed.
- An association table in which age and sex are associated with identification information on an exercise pattern is stored in advance in, for example, the pattern storage unit 122 .
- the control unit 20 identifies identification information associated with user's age and sex in the association table. Then, data on an exercise pattern indicated by the identified identification information is read from the pattern storage unit 122 and stored in the storage area 124 B of the execution pattern information storage unit 124 .
- association table eight pieces of identification information respectively indicating eight exercise patterns may be stored so as to be associated with each physical information or identification information indicating one exercise pattern may be stored so as to be associated with each of physical information.
- identification information indicating one exercise pattern may be stored so as to be associated with each of physical information.
- data on an exercise pattern indicated by identified identification information and data on seven exercise patterns with load levels continuous with a load level of the exercise pattern may be selected.
- the pointer PN is set so as to point to data PT 1 on an exercise pattern.
- an x-axis shows the exercise time per exercise
- a y-axis shows the load level (the number of breaths per certain period of time (e.g., minute) (i.e., a breathing cycle))
- a z-axis shows the number of days (the number of exercises).
- exercise patterns are set such that the load level increases as the number of days (the number of exercises) increases, i.e., such that the number of breathes per certain period of time decreases.
- Exercise pattern data PT 1 to PT 8 respectively correspond to days 1 to 8 .
- each exercise pattern is a pattern that the load gradually increases from the start of exercise (the number of breaths per certain period of time decreases). By this, the user can warm up and then do substantial breathing exercise.
- the load may be constant.
- not only a warm-up period but also a cool-down period may be provided.
- FIG. 7 shows an example of an exercise pattern for a first time (corresponding to the exercise pattern data PT 1 ), and (B) of FIG. 7 shows an example of an exercise pattern for a second time (corresponding to the exercise pattern data PT 2 ).
- an exercise period includes a warm-up period, a substantial exercise period, and a cool-down period.
- a breathing cycle T 1 during the substantial exercise period is longer than a breathing cycle T′ 1 during the warm-up period and the cool-down period.
- a depth B of breathing during the substantial exercise period is greater than a depth B′ of breathing during the warm-up period and the cool-down period.
- a breathing cycle T 2 during the substantial exercise period is longer than a breathing cycle T′ 2 during the warm-up period and the cool-down period.
- a depth B of breathing during the substantial exercise period is greater than a depth B′ of breathing during the warm-up period and the cool-down period.
- the breathing cycle T 2 during the substantial exercise period in the exercise pattern for the second time is longer than the breathing cycle T 1 during the substantial exercise period in the exercise pattern for the first time. As such, the breathing cycle becomes longer as the load level increases.
- step S 106 the control unit 20 reads a stored value of the latest effect index.
- the effect index to be read here is, for example, effect index data Elba (n ⁇ 1) which indicates the degree of decrease in blood pressure for before and after exercise.
- step S 107 an update of the pointer PN is performed based on the read effect index data Elba (n ⁇ 1).
- the pointer PN is updated to point to data on a next exercise pattern (an exercise pattern with a one-step higher load level). For example, when the pointer PN points to the exercise pattern data PT 2 first, an update is performed to point to the exercise pattern data PT 3 .
- the latest effect index data Elba (n ⁇ 1) exceeds the predetermined range, for example, a process such as that shown below is performed.
- the pointer PN when the latest effect index data Elba (n ⁇ 1) exceeds an upper limit of the range, the pointer PN is updated to point to data on an exercise pattern which is the one after the next one (an exercise pattern with a two-step higher load level). For example, when the pointer PN points to the exercise pattern data PT 2 first, an update is performed to point to the exercise pattern data PT 4 . In contrast, when the latest effect index data Elba (n ⁇ 1) falls below a lower limit of the range, the pointer PN is not updated and is allowed to point to the same exercise pattern data as the last one.
- step S 105 or step S 107 When the process in either step S 105 or step S 107 is completed, processing is returned to the main routine.
- an exercise pattern is selected according to the degree of achievement (the degree of improvement/deterioration) of the user him/herself.
- the effect index is a good result
- the user can also reach a target value earlier.
- the present invention is not limited to such a technique.
- the user may be allowed to continue exercise with a lower load.
- the pointer PN may not be updated and may be allowed to point to the same exercise pattern data as the last one.
- step S 106 a stored value of the latest effect index is read and an exercise pattern is selected based on the read value
- an exercise pattern may be selected based on a stored value of the latest characteristic value.
- an exercise pattern with a two-step higher load level is selected, and when the effect index falls below a lower limit, the same exercise pattern as the last one is selected.
- the present invention is not limited to such a process.
- an exercise pattern with a three-step higher load level may be selected, and when the effect index falls below a predetermined threshold which is lower than the above-described upper limit, an exercise pattern may be re-set again.
- the upper and lower limits may be determined in advance for each exercise pattern.
- an exercise pattern may be newly re-set. For example, in such a case, exercise pattern data with a one- or more-step higher load level than that of the exercise pattern data PT 8 is read from the pattern storage unit 122 . The read exercise pattern data may be overwritten in the storage area 124 B or may be stored in another storage area. When an exercise pattern is thus newly re-set, physical information stored in the storage area 124 A may be used again.
- control unit 20 may calculate each parameter of an exercise pattern based on physical information on a subject and a predetermined computational expression. Alternatively, only one exercise pattern may be stored in advance.

- Level-display is performed by highlighting/not highlighting 14 blocks, as with the breathing guide. Of the 14 blocks, seven blocks displayed on the upper side represent improvement and seven blocks displayed on the lower side represent deterioration. Note that it is assumed that levels (level ⁇ 7 to level +7) are predetermined according to the value of the degree of decrease in blood pressure.
- FIG. 11 of the seven blocks located on the upper side, the first to fourth blocks from the center are displayed highlighted (displayed darkened) and the fifth block from the center is displayed blinking.
- the user is informed that a blood pressure value for this time is reduced (improved) by five levels, as compared with a blood pressure value for the first time.

- An effect index for during exercise or for after each exercise may be further displayed.
- the user may be allowed to select an effect index he/she wants to display and a trend of the selected effect index may be displayed.
- the characteristic value calculating unit 203 calculates a blood pressure value itself as a characteristic value of the user, when the exercise index is other than the blood pressure value, specifically, a characteristic value such as that shown below is calculated.
- the characteristic value calculating unit 203 calculates, for example, a heart rate fluctuation as a characteristic value.
- a heart rate fluctuation specific processes in steps S 4 , S 14 , and S 20 in FIG. 4 are different from those for the case of a blood pressure value.
- the biological information detection control unit 202 performs detection control of biological information.
- the characteristic value calculating unit 203 calculates basic information, i.e., heart rate, to calculate a characteristic value. Thereafter, after a predetermined period of time has elapsed, the biological information detection control unit 202 performs detection control of biological information again.
- the characteristic value calculating unit 203 calculates basic information, i.e., heart rate, to calculate a characteristic value. Based on the two heart rates thus calculated, the characteristic value calculating unit 203 calculates a heart rate fluctuation ( ⁇ HR). Note that for procedures of calculation of heart rate and a heart rate fluctuation any known procedure can be used. Note also that biological information for this case is information for calculating a heart rate fluctuation and thus may be electrocardiographic waveform information.

- a suspension period may be preset in an exercise pattern in advance.
- the effect index calculating unit 204 calculates the degree of suppression of the autonomic nervous activity level based on two heart rate fluctuations ( ⁇ HR).
- the characteristic value calculating unit 203 calculates, for example, BRS (Baroreflex Sensitivity) as a characteristic value.
- the BRS is calculated by, for example, “blood pressure fluctuation ( ⁇ BP)/heart rate fluctuation ( ⁇ HR)”.
- ⁇ BP blood pressure fluctuation
- ⁇ HR heart rate fluctuation
- the BRS is an index indicating how much the blood pressure value increases when the heart rate is changed by providing stimulation to autonomic nerves by deep breathing. The higher the value, the more baroreflex sensitivity is reduced. That is, it can be evaluated that blood pressure stability is low and thus the user is unhealthy.
- steps S 4 , S 14 , and S 20 in FIG. 4 a process similar to that for when calculating a heart rate fluctuation is performed. Note that when calculating BRS, as the above-described basic information, a blood pressure value and heart rate are calculated, and based on the calculated two of blood value and heart rate, BRS is calculated.

- step S 204 the pattern changing unit 208 changes an exercise pattern being executed to a higher load pattern. More specifically, for example, exercise time is made longer than a set value. Alternatively, the depth of breathing may be made greater than a set value. Alternatively, these may be combined or other parameters (e.g., the intensity of breathing, a ratio between an exhalation period and an inhalation period, etc.) may be changed.
- processing proceeds to step S 206 .
- step S 206 the pattern changing unit 208 determines whether the calculated value of an effect index for during exercise falls below a predetermined lower limit.

Abstract
Description
- This application is a National Stage application of PCT/JP2006/325900, filed Dec. 26, 2006, which claims the benefit of priority of Japanese Application No. 2006-012879, filed Jan. 20, 2006, the entire contents of these applications hereby incorporated by reference.
- The present invention relates to a breathing exerciser and more particularly to a breathing exerciser that guides an exercise pattern of breathing.
- It has been verified that slow deep breathing leads to suppression of autonomic nerves, providing an effect of decreasing blood pressure. For example, the document “Slow Breathing Improves Arterial Baroreflex Sensitivity and Decreases Blood Pressure in Essential Hypertension” (hereinafter, referred to as the “Non-Patent
Document 1”) by Chacko N. Joseph, et al., in “Hypertension, October 2005”, Volume 46, pp. 714-718, published by the American Heart Association, can be a reference document. Therefore, conventionally, as autonomic nervous system exercise methods and biofeedback, studies have been conducted. Also, a number of breathing exercisers for that have been proposed. - Japanese Patent Application Laid-Open No. 62-277976 (hereinafter, referred to as the “
Patent Document 1”) has disclosed an invention related to an abdominal breathing exercising apparatus in which a sensor that detects movement of the abdominal cavity caused by subject's abdominal breathing is placed on his/her abdomen, a predetermined ideal breathing exercise pattern is generated, an actual breathing pattern is compared with the ideal breathing exercise pattern to determine the degree of matching, and a result of the determination is informed by sound or photoelectric display. Japanese Patent Application Laid-Open No. 2002-301047 (hereinafter, referred to as the “Patent Document 2”) has disclosed an invention related to a breathing induction apparatus including a breathing detecting means of detecting breathing of a living body, in which breathing information is extracted from a detected breathing signal, the information is compared for determination with target breathing pattern information to be induced, and a stimulus signal to be provided to the living body is controlled by a correction value which is based on a difference obtained by the comparison. Published Japanese Translation of PCT Application No. 2005-535378 (hereinafter, referred to as the “Patent Document 3”) has disclosed that during breathing exercise one or more timing parameters for operation of breathing are changed. - It has become clear that respiratory standstill during sleep due to airway obstruction or autonomic nervous system abnormalities, which is a so-called “Sleep Apnea Syndrome (SAS)”, not only simply reduces sleep quality, causing drowsiness during daytime active hours but also promotes hypertension and thereby induces harmful blood pressure fluctuations, which becomes a cause of many serious diseases such as heart diseases and brain diseases.
- As treatment approaches for the SAS, there have been proposed an apparatus (CPAP) that delivers a positive pressure of air to the obstructed airway, a surgical operation for expanding the airway, medical treatment (application of an alveolar surfactant preparation to the posterior region of the pharynx (see Published Japanese Translation of PCT Application No. 2001-507364 (hereinafter, referred to as the “
Patent Document 4”)), enhancement of the muscle groups by muscle strength stimulation exercise by low frequency vibration of the muscle groups of the tongue root in the cervical region (see Japanese Patent Application Laid-Open No. 2005-237807 (hereinafter, referred to as the “Patent Document 5”)), etc. However, any of the approaches is a great burden for patients and the current state is that low-burden approaches to the prevention of the SAS have not been proposed. - Therefore, for the prevention of the SAS also, breathing exercise that patients can easily do is considered to be useful.

- However, the
Patent Documents 1 to 3 all have disclosed techniques for merely approximating an actual breathing state to an ideal breathing pattern and thus there is a problem that even if exercise is done with them, a user cannot grasp a final effect (e.g., a decrease in blood pressure, an increase in blood pressure stability, or the like). This is because it is difficult to grasp a cause-and-effect relationship between such an exercise action as breathing and an improvement target (e.g., a blood pressure value).

- Embodiments of the present invention will be described in detail with reference to the drawings. Note that the same or corresponding parts are denoted by the same reference numerals throughout the drawings.
-
FIG. 1 is a diagram showing a schematic view of abreathing exerciser 100 in a first embodiment of the present invention. - Referring to
FIG. 1 , thebreathing exerciser 100 according to the present embodiment includes an exercisermain body 1; acuff 2 which is placed on a predetermined body part of a user to pressurize by air pressure; and anair tube 3 connecting the exercisermain body 1 and thecuff 2. - The exerciser
main body 1 includes adisplay unit 4 provided so that the user can check display content; and anoperation unit 21 provided so that the user can externally operate the exerciser. Theoperation unit 21 includes a plurality of switches and has a menu switch 21.1 for inputting an instruction to display a variety of menus of thebreathing exerciser 100; a set switch 21.2 for inputting an instruction to perform a menu or each operation; a start switch 21.3 for inputting an instruction to start exercise; left and right scroll switches 21.4; and the like. -
FIG. 2 is a block diagram showing a configuration of thebreathing exerciser 100 in the first embodiment of the present invention. Referring toFIG. 2 , thebreathing exerciser 100 includes a biologicalinformation detecting unit 30 for detecting biological information on the user; acontrol unit 20 for intensively controlling and monitoring each unit; adisplay unit 4; amemory 12 in which various data and programs are to be stored; anoperation unit 21; atimer 13 that performs a timer operation to output timer data; and anaudio output unit 24. In the present embodiment, the biologicalinformation detecting unit 30 includes acuff 2; anair bag 25 contained in thecuff 2; apressure sensor 14, the capacity of which changes by pressure (hereinafter, referred to as “cuff pressure”) in theair bag 25; anoscillator circuit 15 that outputs a signal with an oscillation frequency depending on a capacitance value of thepressure sensor 14, to thecontrol unit 20; apump 16 and avalve 18 for adjusting the level of the cuff pressure; apump drive circuit 17 that drives thepump 16; and avalve drive circuit 19 for adjusting the degree of open/close of thevalve 18. Theair bag 25 is connected to thepressure sensor 14, thepump 16, and thevalve 18 via anair tube 3. Note that the biologicalinformation detecting unit 30 is not limited to such a configuration and any configuration can be employed as long as biological information for calculating a characteristic value, which will be described later, can be detected. - The
control unit 20 is configured by, for example, a CPU (Central Processing Unit). Thecontrol unit 20 includes aguide unit 201 for guiding an exercise pattern of breathing to the user; a biological informationdetection control unit 202 for controlling detection of biological information at timing associated with an exercise period; a characteristicvalue calculating unit 203 for calculating a biological characteristic value that reflects an exercise index, based on the detected biological information; an effectindex calculating unit 204 for calculating an effect index based on at least two characteristic values calculated by the characteristicvalue calculating unit 203; and an informingunit 206 for informing the effect index calculated by the effectindex calculating unit 204 to the user. - Here, the “exercise index” is an index serving as a target (improvement target) for breathing exercise and represents, for example, a blood pressure value, an autonomic nervous activity level index, a blood pressure stability index, etc. The “effect index” is an index representing an effect of breathing exercise. The effect index for when the exercise index is a blood pressure value is the degree of decrease in blood pressure value. The effect index for when the exercise index is an autonomic nervous activity level index is the degree of suppression of an autonomic nervous activity level. The effect index for when the exercise index is a blood pressure stability index is the degree of increase in blood pressure stability. In the present embodiment, description is made with the exercise index being a blood pressure value.
- The “exercise period” is a period during which an exercise pattern is guided by the
guide unit 201. - Note that a
pattern changing unit 208 shown inFIG. 2 is shown to describe a second embodiment, which will be described later, and thus does not need to be included in thecontrol unit 20 of thebreathing exerciser 100 in the first embodiment. - The
guide unit 201 specifically performs a process of displaying information (hereinafter, also referred to as a “breathing guide”) for guiding to breathing which is based on an exercise pattern, on thedisplay unit 4. Note that although in the present embodiment description is made such that an exercise pattern is guided using thedisplay unit 4, an exercise pattern may be guided by sound by theaudio output unit 24. - The biological information
detection control unit 202 performs detection control of biological information, i.e., pulse wave information, at timing associated with an exercise period. Specifically, the biological informationdetection control unit 202 controls the drive of thepump drive circuit 17 and thevalve drive circuit 19 to convert a signal obtained from theoscillator circuit 15 into a pressure signal and thereby detects pressure. - The characteristic
value calculating unit 203 specifically calculates a blood pressure value (systolic blood pressure and diastolic blood pressure) by applying a predetermined algorithm to detected pressure data (pulse wave information). As such, as a characteristic value for when the exercise index is a blood pressure value, a blood pressure value which is the same as the exercise index is calculated. For a procedure of calculation of a blood pressure value, any known procedure which is conventionally provided can be used. Note that with the above-described configuration pulse rate (heart rate) can also be calculated by applying a predetermined algorithm to detected pressure data. - The effect
index calculating unit 204 calculates, based on calculated characteristic values, effect indices respectively for before exercise, during exercise, after exercise, and before and after exercise. Each effect index is specifically calculated using, for example, a difference between two characteristic values or a ratio between two characteristic values. In the present embodiment, as an effect index, the degree of decrease in blood pressure value (ΔBP) is calculated. - An effect index for before exercise is calculated using a characteristic value which is based on biological information detected before (immediately before) a previous exercise period and a characteristic value which is based on biological information detected before (immediately before) a current exercise period. The “previous exercise period” refers to an exercise period in a breathing exercise process which is performed earlier than a current breathing exercise process, and may be, for example, the first exercise period or may be the last exercise period. In the following description, it is assumed that an effect index for before each exercise is calculated based on a characteristic value obtained before the first exercise period and a characteristic value obtained before a current exercise period.
- An effect index for during exercise is calculated using characteristic values which are based on biological information detected during an exercise period by the biological information
detection control unit 202. For example, an effect index for during exercise is calculated based on two characteristic values obtained during an exercise period. Alternatively, an effect index for during exercise may be calculated based on a characteristic value obtained before an exercise period and a characteristic value obtained during the exercise period. - An effect index for after each exercise is, as with the effect index for before exercise, calculated using a characteristic value which is based on biological information detected after (immediately after) a previous exercise period and a characteristic value which is based on biological information detected after (immediately after) a current exercise period. In the following description, it is assumed that an effect index for after each exercise is calculated based on a characteristic value obtained after the first exercise period and a characteristic value obtained after a current exercise period.
- An effect index for before and after exercise is calculated using a characteristic value which is based on biological information detected before a current exercise period and a characteristic value which is based on biological information detected after the current exercise period.
- Although in the present embodiment effect indices are thus calculated before exercise, during an exercise period, after exercise, and before and after exercise, at least one of such effect indices may be calculated. Alternatively, in addition to them/instead of them, for example, an effect index may be calculated based on a characteristic value obtained during a current exercise period and a characteristic value obtained after the current exercise period.
- The
control unit 20 may further calculate a change (trend) of the effect of breathing exercise, based on a difference between a past effect index and a current effect index. Alternatively, thecontrol unit 20 may compute a current target value based on a predetermined computational expression and a past effect index to calculate a shift of a current effect index from the target value. - The informing
unit 206 specifically performs a process of displaying information on a calculated effect index, on thedisplay unit 4. The informingunit 206 may further display a trend of the effect index on thedisplay unit 4. - The operation of each block in the
control unit 20 may be implemented by executing software stored in thememory 12 or at least one of the blocks may be implemented by hardware. - The
memory 12 is a non-volatile memory, e.g., flash memory. Thememory 12 includes apattern storage unit 122 in which data on a plurality of exercise patterns are stored in advance; an execution patterninformation storage unit 124 for storing information about an exercise pattern (hereinafter, also referred to as an “execution pattern”) to be executed in user's breathing exercise; and an exerciseresult storage unit 126 for storing exercise results. Note that the storage units do not need to be included in the same storage medium (memory 12) and may be included in different storage media. Specific examples of data structures in the execution patterninformation storage unit 124 and the exerciseresult storage unit 126 will be described with reference toFIGS. 3A and 3B . -
FIGS. 3A and 3B are diagrams respectively showing exemplary structures of the execution patterninformation storage unit 124 and the exerciseresult storage unit 126 in the first embodiment of the present invention. - Referring to
FIG. 3A , the execution patterninformation storage unit 124 includes astorage area 124A for storing user's physical information; and astorage area 124B for storing data on exercise patterns to be executed. In thestorage area 124A, user's age data AG and sex data SX are stored. In thestorage area 124B, for example, data PT1 to PT8 on eight exercise patterns is stored in ascending order of load levels. The data on eight exercise patterns is selected from data on a plurality of exercise patterns stored in thepattern storage unit 122. Note that a specific selection method will be described later. - The exercise pattern data includes information on at least exercise time or the number of breaths, a breathing cycle, and the depth of breathing. The load level is determined by, for example, at least one of parameters including at least exercise time or the number of breaths, a breathing cycle, and the depth of breathing. In the present embodiment, it is assumed that the load level is determined by a breathing cycle (the number of breaths per certain period of time).
- The execution pattern
information storage unit 124 further includes a pointer PN that points to data on an exercise pattern to be executed this time (or next time) among the data PT1 to PT8 on eight exercise patterns stored in thestorage area 124B. Note that although here management of an exercise pattern to be executed is performed by the pointer PN, the present invention is not limited to such a technique as long as which exercise pattern is executed this time or which exercise pattern has been executed last time can be identified. - Referring to
FIG. 3B , in the exerciseresult storage unit 126, exercise results are stored in the unit of record R. The record R includes date and time data DT indicating exercise data and time; blood pressure data Tlb indicating a blood pressure value (characteristic value) for before exercise; blood pressure data Tlt and Tlt′ indicating blood pressure values (characteristics values) for during exercise; blood pressure data Tla indicating a blood pressure value (characteristic value) for after exercise; effect index data Elb indicating the degree of decrease in blood pressure value (effect index) for before exercise; effect index data Elba indicating the degree of decrease in blood pressure value (effect index) for before and after exercise; and effect index data Ela indicating the degree of decrease in blood pressure value (effect index) for after each exercise. Note that such data is not limited to a storage format using the record R as long as the data is stored so as to be associated with each exercise. - (For Operation)
-
FIG. 4 is a flowchart showing a flow of a breathing exercise process in the first embodiment of the present invention. The process shown in the flowchart inFIG. 4 is stored in advance in thememory 12 as a program and a function of the breathing exercise process is implemented by thecontrol unit 20 reading and executing this program. Note that for simplification of description it is assumed that a series of breathing exercise process for this time is an nth one (n: natural number). - Referring to
FIG. 4 , a flow of a processing operation will be described below. First, an exercise pattern determination process which will be described later using a subroutine is performed (step S2). - Then, a biological information detection process and a characteristic value calculation/storage process are performed (step S4). Specifically, first, the biological information
detection control unit 202 performs control to detect biological information and the characteristicvalue calculating unit 203 calculates a characteristic value, i.e., a blood pressure value (e.g., a systolic blood pressure value), based on detected biological information (pulse wave information). Then, data on the calculated blood pressure value (data on the characteristic value) is stored in the exerciseresult storage unit 126 as blood pressure data Tlbn. Note that at the time of or before detecting biological information, the user may be urged to take a deep breath. - Subsequently, a calculation/informing/storage process of an effect index for before each exercise is performed (step S6). Specifically, the effect
index calculating unit 204 calculates an effect index, i.e., the degree of decrease in blood pressure value, for before each exercise, based on blood pressure data Tlbn for this time which is calculated and stored in step S4 and blood pressure data Tlb1 for the first time. Information indicating the calculated degree of decrease in blood pressure value is displayed in a predetermined area of thedisplay unit 4. By this, the degree of decrease in blood pressure value for this time with reference to a blood pressure value for the first time can be informed to the user. Furthermore, the calculated degree of decrease in blood pressure value for before each exercise is stored as effect index data Elbn. - Next, it is determined whether an instruction to start exercise has been inputted (step S8). Specifically, it is determined whether the start switch 21.3 has been pressed by the user. The
control unit 20 waits until an input of a start instruction has been detected (NO in step S8). If an input of a start instruction has been detected (YES in step S8), then processing proceeds to step S10. Note that although here breathing exercise starts after an instruction from the user has been inputted, breathing exercise may automatically start after an effect index has been informed (after the process in step S6). - In step S10, the
guide unit 201 guides an exercise pattern determined in step S2 to the user. Specifically, a breathing guide (e.g., how much more exhalation or inhalation should be performed) is displayed on thedisplay unit 4 based on exercise pattern data pointed to by the pointer PN in the execution patterninformation storage unit 124. - Then, it is determined whether evaluation timing has come (step S12). The evaluation timing may be predetermined such as every five minutes, for example, after the start of exercise, or whether it is evaluation timing may be determined by an instruction from the user. If it is determined that evaluation timing has come (YES in step S12), then processing proceeds to step S14. On the other hand, if it is determined that evaluation time has not come (NO in step S12), then processing proceeds to step S18.
- In step S14, a biological information detection process and a characteristic value calculation/storage process are performed again. The processes for biological information detection and characteristic value calculation here can be performed in the same manner as that for step S4. A calculated characteristic value (data on a blood pressure value) is stored in the exercise
result storage unit 126 as blood pressure data Tltn (blood pressure data Tlt′n if it is a second time). - Then, a calculation/informing process of an effect index for during exercise is performed (step S16). In step S16, specifically, the effect
index calculating unit 204 calculates an effect index, i.e., the degree of decrease in blood pressure value, for during exercise based on, for example, the blood pressure data Tltn and blood pressure data Tlt′n calculated and stored in step S14. Alternatively, an effect index for during exercise may be calculated based on the blood pressure data Tlbn calculated and stored in step S4 and the blood pressure data Tltn calculated and stored in step S14. Information on the calculated degree of decrease in blood pressure value is displayed in a predetermined area of thedisplay unit 4. By this, the degree of decrease in blood pressure value for during exercise can be informed to the user. - In step S18, it is determined whether an exercise period has elapsed. If an exercise period has not elapsed (NO in step S18), then processing returns to step S10. On the other hand, if it is determined that an exercise period has elapsed (YES in step S18), then processing proceeds to step S20.
- In step S20, a biological information detection process and a characteristic value calculation/storage process are further performed. The processes for biological information detection and characteristic value calculation here can also be performed in the same manner as that for step S4. A calculated characteristic value (data on a blood pressure value) is stored in the exercise
result storage unit 126 as blood pressure data Tlan. Note that at the time of or before detecting biological information in step S20, the user may be urged to take a deep breath. - Subsequently, a calculation/informing/storage process of an effect index for before and after exercise is performed (step S21). Specifically, the effect
index calculating unit 204 calculates an effect index, i.e., the degree of decrease in blood pressure value, for before and after exercise based on the blood pressure data Tlbn for before exercise which is calculated and stored in step S4 and the blood pressure data Tlan for after exercise which is calculated and stored in step S20. Information on the calculated degree of decrease in blood pressure value is displayed in a predetermined area of thedisplay unit 4. By this, the degree of decrease in blood pressure value for after exercise with reference to a blood pressure value for before exercise can be informed to the user. Furthermore, the calculated degree of decrease in blood pressure value for before and after exercise is stored as effect index data Elban. - Furthermore, a calculation/informing/storage process of an effect index for after each exercise is performed (step S22). Specifically, the effect
index calculating unit 204 calculates an effect index, i.e., the degree of decrease in blood pressure value, for after each exercise based on the blood pressure data Tlan for this time which is calculated and stored in step S20 and the blood pressure data Tla1 for the first time. Information on the calculated degree of decrease in blood pressure value is displayed in a predetermined area of thedisplay unit 4. By this, the degree of decrease in blood pressure value for this time with reference to the blood pressure value for the first time can be informed to the user. Furthermore, the calculated degree of decrease in blood pressure value for after each exercise is stored as effect index data Elan. - Next, it is determined whether there is a past effect index (an effect index associated with a previous exercise period) (step S24). If it is determined that a past effect index is stored in the exercise result storage unit 126 (YES in step S24), then processing proceeds to step S26. On the other hand, if a past effect index is not stored (NO in step S24), then the breathing exercise process ends.
- In step S26, the informing
unit 206 displays a trend between the past effect index and the effect index for this time on thedisplay unit 4. By this, the trend of the effect index is informed to the user. When the process in step S26 is completed, the series of breathing exercise process ends. - Next, the exercise pattern determination process (S2) will be described.
FIG. 5 is a flowchart showing the exercise pattern determination process in the first embodiment of the present invention. - Referring to
FIG. 5 , first, thecontrol unit 20 determines whether an exercise pattern is already set (step S102). If an exercise pattern is not already set (NO in step S102), then processing proceeds to step S104. On the other hand, if an exercise pattern is already set (YES in step S102), then processing proceeds to step S106. - In step S104, the
control unit 20 accepts an input of physical information (e.g., age, sex, etc.) from the user and stores the physical information in thestorage area 124A of the execution patterninformation storage unit 124. When the process in step S104 is completed, processing proceeds to step S105. - In step S105, an exercise pattern setting/storage process is performed based on the accepted physical information. Specifically, for example, a process such as that below is performed. An association table in which age and sex are associated with identification information on an exercise pattern is stored in advance in, for example, the
pattern storage unit 122. Thecontrol unit 20 identifies identification information associated with user's age and sex in the association table. Then, data on an exercise pattern indicated by the identified identification information is read from thepattern storage unit 122 and stored in thestorage area 124B of the execution patterninformation storage unit 124. Note that in the association table eight pieces of identification information respectively indicating eight exercise patterns may be stored so as to be associated with each physical information or identification information indicating one exercise pattern may be stored so as to be associated with each of physical information. In the former case, for example, data on an exercise pattern indicated by identified identification information and data on seven exercise patterns with load levels continuous with a load level of the exercise pattern may be selected. In such a case, the pointer PN is set so as to point to data PT1 on an exercise pattern. - In
FIG. 6 , an x-axis shows the exercise time per exercise, a y-axis shows the load level (the number of breaths per certain period of time (e.g., minute) (i.e., a breathing cycle)), and a z-axis shows the number of days (the number of exercises). As shown inFIG. 6 , exercise patterns are set such that the load level increases as the number of days (the number of exercises) increases, i.e., such that the number of breathes per certain period of time decreases. Exercise pattern data PT1 to PT8 respectively correspond todays 1 to 8. Note that in the drawing each exercise pattern is a pattern that the load gradually increases from the start of exercise (the number of breaths per certain period of time decreases). By this, the user can warm up and then do substantial breathing exercise. Note that during an exercise period, the load may be constant. Alternatively, during an exercise period, not only a warm-up period but also a cool-down period may be provided. - (A) of
FIG. 7 shows an example of an exercise pattern for a first time (corresponding to the exercise pattern data PT1), and (B) ofFIG. 7 shows an example of an exercise pattern for a second time (corresponding to the exercise pattern data PT2). Note that here an example of the case is shown in which an exercise period includes a warm-up period, a substantial exercise period, and a cool-down period. - Referring to (A) of
FIG. 7 , a breathing cycle T1 during the substantial exercise period is longer than a breathing cycle T′1 during the warm-up period and the cool-down period. Also, a depth B of breathing during the substantial exercise period is greater than a depth B′ of breathing during the warm-up period and the cool-down period. Also, in (B) ofFIG. 7 , similarly, a breathing cycle T2 during the substantial exercise period is longer than a breathing cycle T′2 during the warm-up period and the cool-down period. Also, a depth B of breathing during the substantial exercise period is greater than a depth B′ of breathing during the warm-up period and the cool-down period. - Referring to
FIG. 7 , the breathing cycle T2 during the substantial exercise period in the exercise pattern for the second time is longer than the breathing cycle T1 during the substantial exercise period in the exercise pattern for the first time. As such, the breathing cycle becomes longer as the load level increases. - In step S106, the
control unit 20 reads a stored value of the latest effect index. The effect index to be read here is, for example, effect index data Elba (n−1) which indicates the degree of decrease in blood pressure for before and after exercise. When the process in step S106 is completed, processing proceeds to step S107. - In step S107, an update of the pointer PN is performed based on the read effect index data Elba (n−1). When the latest effect index data Elba (n−1) is within a predetermined range, the pointer PN is updated to point to data on a next exercise pattern (an exercise pattern with a one-step higher load level). For example, when the pointer PN points to the exercise pattern data PT2 first, an update is performed to point to the exercise pattern data PT3. On the other hand, when the latest effect index data Elba (n−1) exceeds the predetermined range, for example, a process such as that shown below is performed. Specifically, when the latest effect index data Elba (n−1) exceeds an upper limit of the range, the pointer PN is updated to point to data on an exercise pattern which is the one after the next one (an exercise pattern with a two-step higher load level). For example, when the pointer PN points to the exercise pattern data PT2 first, an update is performed to point to the exercise pattern data PT4. In contrast, when the latest effect index data Elba (n−1) falls below a lower limit of the range, the pointer PN is not updated and is allowed to point to the same exercise pattern data as the last one.
- When the process in either step S105 or step S107 is completed, processing is returned to the main routine.
- In this manner, an exercise pattern is selected according to the degree of achievement (the degree of improvement/deterioration) of the user him/herself. By this, when the effect index is a good result, the user can also reach a target value earlier. Note that although in the present embodiment when the effect of exercise is high, the load of exercise is further advanced to reach the target value early, the present invention is not limited to such a technique. For example, when the effect is high, in contrast, the user may be allowed to continue exercise with a lower load. Specifically, when the latest effect index data Elba (n−1) exceeds the upper limit, the pointer PN may not be updated and may be allowed to point to the same exercise pattern data as the last one.
- Note that although in step S106 a stored value of the latest effect index is read and an exercise pattern is selected based on the read value, an exercise pattern may be selected based on a stored value of the latest characteristic value. In this case, it is desirable to select an exercise pattern based on blood pressure data Tlb (n−1) for before exercise that reflects a blood pressure value of the user during the course of a usual day of activities.
- Note that, as described above, when the effect index exceeds a predetermined upper limit, an exercise pattern with a two-step higher load level is selected, and when the effect index falls below a lower limit, the same exercise pattern as the last one is selected. However, the present invention is not limited to such a process. For example, when the effect index exceeds a predetermined upper limit, an exercise pattern with a three-step higher load level may be selected, and when the effect index falls below a predetermined threshold which is lower than the above-described upper limit, an exercise pattern may be re-set again.
- The upper and lower limits may be determined in advance for each exercise pattern.
- When the pointer PN points to the exercise pattern data PT8, and an immediately preceding effect index does not fall below the lower limit, an exercise pattern may be newly re-set. For example, in such a case, exercise pattern data with a one- or more-step higher load level than that of the exercise pattern data PT8 is read from the
pattern storage unit 122. The read exercise pattern data may be overwritten in thestorage area 124B or may be stored in another storage area. When an exercise pattern is thus newly re-set, physical information stored in thestorage area 124A may be used again. - As described above, in the present embodiment, description is made such that data on a plurality of exercise patterns is stored in advance in the
pattern storage unit 122. However, thecontrol unit 20 may calculate each parameter of an exercise pattern based on physical information on a subject and a predetermined computational expression. Alternatively, only one exercise pattern may be stored in advance. - Although in the present embodiment setting of a plurality of exercise patterns is performed first, each time exercise is done one exercise pattern may be selected from the
pattern storage unit 122. - (For Exemplary Display)

FIG. 8 is a diagram showing an example of a screen to be displayed when inputting physical information in step S104. As shown inFIG. 8 , an item (age or sex) of physical information being inputted is displayed blinking. Physical information can be inputted using the scroll switches 21.4 and the set switch 21.2. Note that in order that a plurality of users can use the exerciser a user number may be inputted. In this case, inputted physical information and user number are stored so as to be associated with each other. Similarly, exercise results, etc., are also stored so as to be associated with the user number. -
FIG. 9 is a diagram showing an exemplary display of a breathing guide in step S10. Referring toFIG. 9 , a breathing guide is performed by highlighting/not highlighting 14 blocks displayed in a vertical direction on the screen. Also, the number of exercises (nth time) and remaining time are displayed in their respective predetermined areas. Note that a characteristic value or an effect index for during exercise may be further displayed. Here, an example is shown in which a characteristic value (BRS which will be described later) is displayed. - Detailed exemplary display of the breathing guide will be described with reference to
FIG. 10 . (A) ofFIG. 10 is a diagram showing an example of an exercise pattern and (B) is a diagram showing an exemplary display of the breathing guide at arbitrary times t1 to t8 of the exercise pattern shown in (A). - Referring to (B) of
FIG. 10 , in each breathing guide, a block at a location indicating the depth of breathing is fixedly displayed highlighted (displayed darkened). In the guides at times t1, t2, and t3 during a warm-up period,fifth blocks block 81 is displayed blinking. By this, it is possible to inform the user of how much more time he/she should inhale. In the breathing guide at time t2, similarly, theblock 81 is displayed blinking and all of the first to fourth blocks located upward from the center are displayed highlighted. By this, it is possible to inform that it is the end of an inhalation period. - At times t4, t5, and t6 during a substantial exercise period, seventh blocks (blocks at both ends) 83 and 84 respectively located upward and downward from the center are fixedly displayed highlighted. In the breathing guide at time t5, the
block 84 is displayed blinking and blocks other than theblock 83 are displayed not highlighted (displayed blanked). By this, the user is guided that inhalation is finished and thus the user should move to exhalation. - At times t7 and t8 during a cool-down period, as with the warm-up period,
fifth blocks block 82 is displayed blinking and the first block located upward from the center is displayed highlighted. By this, the user is guided that an exhalation state should be continued for on the order of another one-half. - Note that the display mode of the breathing guide is not limited to highlight/no highlight such as that described above; for example, the display color of blocks may be changed.

FIGS. 11 and 12 are diagrams each showing exemplary display of information on an effect index.FIG. 11 is a diagram showing an exemplary display of information on an effect index for before exercise in step S6 andFIG. 12 is a diagram showing an exemplary display of information on an effect index for before and after exercise in step S21. The exemplary display of information on an effect index for before exercise shown inFIG. 11 may be similar also for the case of an effect index for after exercise. - Referring to
FIGS. 11 and 12 , each effect index is, for example, level-displayed. Level-display is performed by highlighting/not highlighting 14 blocks, as with the breathing guide. Of the 14 blocks, seven blocks displayed on the upper side represent improvement and seven blocks displayed on the lower side represent deterioration. Note that it is assumed that levels (level −7 to level +7) are predetermined according to the value of the degree of decrease in blood pressure. - In
FIG. 11 , of the seven blocks located on the upper side, the first to fourth blocks from the center are displayed highlighted (displayed darkened) and the fifth block from the center is displayed blinking. By this, the user is informed that a blood pressure value for this time is reduced (improved) by five levels, as compared with a blood pressure value for the first time. When performing such level-display, it is desirable that, as shown inFIG. 11 , the blood pressure value for the first time and the blood pressure value for this time are further displayed. By this, the user can grasp the degree of improvement/deterioration in greater detail. - In
FIG. 12 , of the seven blocks located on the upper side, the first and second blocks from the center are displayed highlighted (displayed darkened) and the third block from the center is displayed blinking. By this, the user is informed that a blood pressure value for after exercise is reduced (improved) by three levels, as compared with a blood pressure value for before exercise. In this case too, it is desirable that the blood pressure value (characteristic value) for before exercise and the blood pressure value (characteristic value) for after exercise are further displayed. By this, the user can grasp the degree of improvement/deterioration in characteristic value (blood pressure value) in greater detail. - Note that although here information on an effect index is informed by the level of improvement/deterioration, the present invention is not limited thereto; for example, the value of an effect index (the degree of decrease in blood pressure value) itself may be informed. When displaying information on an effect index, the number of exercises may be further displayed.
-
FIG. 13 is a diagram showing an exemplary display of the trend of the effect index in step S26. InFIG. 13 , a trend of the effect index for before each exercise and a trend of the effect index for before and after exercise, for the first time to this time are displayed. In the drawing, E1, E2, . . . , En each represent an effect index for before and after exercise, i.e., an effect per exercise. Et1, Et2, . . . , Etn each represent an effect index for before each exercise, i.e., a cumulative effect of exercise according to the progression of exercise. By the trends of effect indices thus being displayed, the user can visually grasp short-term/long-term effects of exercise. - Note that instead of showing trends of effect indices for the first time to this time, trends of effect indices for a certain period of time (e.g., for one week) may be displayed.
- An effect index for during exercise or for after each exercise may be further displayed. Alternatively, the user may be allowed to select an effect index he/she wants to display and a trend of the selected effect index may be displayed.
- Note that although in the above description when the exercise index is a blood pressure value, the characteristic
value calculating unit 203 calculates a blood pressure value itself as a characteristic value of the user, when the exercise index is other than the blood pressure value, specifically, a characteristic value such as that shown below is calculated. - When the exercise index is the above-described autonomic nervous activity level index, the characteristic
value calculating unit 203 calculates, for example, a heart rate fluctuation as a characteristic value. When calculating a heart rate fluctuation, specific processes in steps S4, S14, and S20 inFIG. 4 are different from those for the case of a blood pressure value. First, the biological informationdetection control unit 202 performs detection control of biological information. Based on the detected biological information, the characteristicvalue calculating unit 203 calculates basic information, i.e., heart rate, to calculate a characteristic value. Thereafter, after a predetermined period of time has elapsed, the biological informationdetection control unit 202 performs detection control of biological information again. Based on the detected biological information, the characteristicvalue calculating unit 203 calculates basic information, i.e., heart rate, to calculate a characteristic value. Based on the two heart rates thus calculated, the characteristicvalue calculating unit 203 calculates a heart rate fluctuation (ΔHR). Note that for procedures of calculation of heart rate and a heart rate fluctuation any known procedure can be used. Note also that biological information for this case is information for calculating a heart rate fluctuation and thus may be electrocardiographic waveform information. - When calculating a heart rate fluctuation, in steps S4 and S20, it is desirable to inform the user at a time between the first biological information detection control and the second biological information detection control, to take a deep breath, for example, to display the message “Take a deep breath” on the
display unit 4. By this, even before or after exercise, heart rates respectively for before and after a deep breathing state can be calculated. Note, however, that in view of providing stimulation to autonomic nerves, the user may be informed to take a quick breath. In step S14, even during breathing exercise, when performing the second biological information detection, it is desirable to inform to suspend deep breathing, for example, to display the message “Suspend breathing exercise” on thedisplay unit 4. Note that a suspension period may be preset in an exercise pattern in advance. - In steps S6, S16, S21, and S22, the effect
index calculating unit 204 calculates the degree of suppression of the autonomic nervous activity level based on two heart rate fluctuations (ΔHR). - When the exercise index is the above-described blood pressure stability index, the characteristic
value calculating unit 203 calculates, for example, BRS (Baroreflex Sensitivity) as a characteristic value. The BRS is calculated by, for example, “blood pressure fluctuation (ΔBP)/heart rate fluctuation (ΔHR)”. The BRS is an index indicating how much the blood pressure value increases when the heart rate is changed by providing stimulation to autonomic nerves by deep breathing. The higher the value, the more baroreflex sensitivity is reduced. That is, it can be evaluated that blood pressure stability is low and thus the user is unhealthy. - When calculating BRS too, in steps S4, S14, and S20 in
FIG. 4 , a process similar to that for when calculating a heart rate fluctuation is performed. Note that when calculating BRS, as the above-described basic information, a blood pressure value and heart rate are calculated, and based on the calculated two of blood value and heart rate, BRS is calculated. - In steps S6, S16, S21, and S22, the effect
index calculating unit 204 calculates the degree of increase in blood pressure stability (ΔBRS) based on two BRSs. - Note that when heart rate and/or a blood pressure value can be continuously measured in synchronization with breathing, a heart rate fluctuation or BRS may be calculated by a single measurement operation (biological information detection process).
- Although the above first embodiment describes that only one type of characteristic value and one type of effect index are calculated, two or more types of characteristic value and two or more types of effect index may be calculated and the two or more types of effect index may be informed to the user.
- Alternatively, in the present embodiment, an effect index calculated based on two characteristic values is informed to the user. However, as long as the user can grasp an effect of breathing exercise, for example, instead of an effect index, two characteristic values (e.g., a characteristic value for before the first exercise and a characteristic value for before current exercise, etc.) may be informed to the user. In this case, the effect
index calculating unit 204 inFIG. 2 may not be included in thecontrol unit 20. Also, instead of step S6 inFIG. 4 , a characteristic value for before current exercise calculated in step S4 and a characteristic value for before the first exercise are informed. Specifically, for example, these two characteristic values are simultaneously or alternately displayed on thedisplay unit 4. Similarly, instead of step S16, a characteristic value for during exercise calculated in step S14 may be informed. Instead of step S21, a characteristic value for before current exercise calculated in step S14 and a characteristic value for after current exercise calculated in step S20 may be informed. Instead of step S22, a characteristic value for after current exercise calculated in step S20 and a characteristic value for after the first exercise may be informed. Instead of steps S24 and S26, a trend of a characteristic value may be informed. In the exercise pattern determination process shown inFIG. 5 , in step S106, a stored value of the latest characteristic value (e.g., a characteristic value for before exercise) may be read, and an update of the pointer (S107) may be performed based on the latest characteristic value. - Next, a second embodiment of the present invention will be described.
- Although in the first embodiment during breathing exercise an exercise pattern which is determined before the exercise is not changed, in the second embodiment even during breathing exercise the exercise pattern can be changed. Note that the basic configuration of a breathing exerciser in the second embodiment is similar to that of the
breathing exerciser 100 in the first embodiment. Thus, also here description is made using the reference numerals used in the first embodiment. - Differences from the first embodiment will be described below.
- Referring to
FIG. 2 , acontrol unit 20 of abreathing exerciser 100 in the second embodiment further includes apattern changing unit 208, in addition to the units described in the first embodiment. Thepattern changing unit 208 changes an exercise pattern being executed, based on an effect index for during a current exercise period. -
FIG. 14 is a flowchart showing a flow of a breathing exercise process in the second embodiment of the present invention. The process shown in the flowchart inFIG. 14 is stored in advance in amemory 12 as a program and a function of the breathing exercise process is implemented by thecontrol unit 20 reading and executing this program. Note that processes similar to those shown inFIG. 4 are denoted by the same step numbers. - Referring to
FIG. 14 , in the breathing exercise process in the second embodiment, a pattern change process (step S17) is performed between steps S16 and S18. - A flowchart of a subroutine showing the pattern change process is shown in
FIG. 15 .FIG. 15 is a diagram showing the pattern change process in the second embodiment of the present invention. - Referring to
FIG. 15 , first, thepattern changing unit 208 determines whether a calculated value of an effect index for during exercise exceeds a predetermined upper limit (step S202). If it is determined that the calculated value exceeds the upper limit (YES in step S202), then processing proceeds to step S204. On the other hand, if it is determined that the calculated value of an effect index for during exercise is less than or equal to the upper limit (NO in step S202), then processing proceeds to step S206. - In step S204, the
pattern changing unit 208 changes an exercise pattern being executed to a higher load pattern. More specifically, for example, exercise time is made longer than a set value. Alternatively, the depth of breathing may be made greater than a set value. Alternatively, these may be combined or other parameters (e.g., the intensity of breathing, a ratio between an exhalation period and an inhalation period, etc.) may be changed. When the process in step S204 is completed, processing proceeds to step S206. - In step S206, the
pattern changing unit 208 determines whether the calculated value of an effect index for during exercise falls below a predetermined lower limit. If it is determined that the calculated value falls below the lower limit (YES in step S206), then processing proceeds to step S208. On the other hand, if it is determined that the calculated value of an effect index for during exercise is less than or equal to the lower limit (NO in step S206), then processing is returned to the main routine. - In step S208, the
pattern changing unit 208 changes an exercise pattern being executed to a lower load pattern. More specifically, for example, exercise time is made shorter than a set value. Alternatively, the depth of breathing may be made smaller than a set value. Alternatively, these may be combined or other parameters may be changed. When the process in step S208 is completed, processing is returned to the main routine. - As such, in the second embodiment, when such a real-time effect index as an effect index for during exercise exceeds a predetermined range, an exercise pattern can be flexibly changed to a pattern appropriate for the user.
- Note that the upper and lower limits used in the pattern change process may be the same as those used when determining an exercise pattern in the first embodiment.
- Although in the second embodiment an exercise pattern is changed based on an effect index for during exercise, an exercise pattern may be changed based on a characteristic value for during exercise. In this case too, for example, an exercise pattern is changed according to whether a characteristic value for during exercise exceeds a predetermined upper limit or exceeds a predetermined lower limit.
- A breathing exercise method to be performed by the breathing exerciser of the present invention can also be provided in the form of a program. Such a program can also be provided in the form of a program product by storing the program on an optical medium, such as a CD-ROM (Compact Disk-ROM), or in a computer-readable storage medium, such as a memory card. Alternatively, the program can also be provided by download via a network.
- A program product to be provided is executed by being installed in a program storage unit such as the
memory 12. Note that the program product includes a program itself and a storage medium storing the program. - The embodiments disclosed herein are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is indicated by the appended claims rather than by the foregoing description, and all changes that come within the meaning and range of equivalency of the appended claims are intended to be embraced therein.
