Description

  The present invention relates to an exercise support system and an exercise support method for supporting user exercise by providing exercise content from a center device to a user terminal using a communication network.

  In indoor exercises for the purpose of daily physical fitness and health promotion, do not exercise excessively at once, but continue appropriate exercise that matches the user's physical strength and exercise ability. is important. However, in general, personal exercises that are performed indoors are often performed by referring to media such as books, television programs, and videos, and depending on the physical strength and athletic ability of the individual user who performs the exercise, excessive exercise is forced. It might be. In addition, the provided exercise menu tends to be uniform, and the same exercise menu is repeatedly presented, so that it is easy for the user to get bored and it is difficult to continue the exercise.

  Therefore, a background video representing a landscape suitable for the exercise performed by the user is displayed, and a user-related video is simultaneously displayed in the background video, and the actual motion of the user and the biological function of the user are displayed. A body training device having a function of changing in cooperation with (fatigue degree) has been proposed (see, for example, Patent Document 1).

JP-A-11-128392 (FIG. 1)

  However, in the above-described physical training device, the change in the video content according to the user's biological function is expressed by the appearance frequency of the balloon for maintaining and continuing the motivation for the video reproduction speed and exercise. For this reason, it is effective in the case of an exercise that requires repetition of a certain movement such as jogging, but is not suitable for an exercise that requires various movements such as stretching exercise, dance, and gymnastics. This is because it is important to trace the correct movements for movements that require this kind of complicated movement, and it is necessary to change the playback speed or perform actions other than those originally required, such as breaking the balloon. This is because requesting the user may hinder the exercise performed by the user and may halve the effect of the exercise.

  The present invention has been made by paying attention to the above circumstances, and the object of the present invention is to always present optimal exercise content according to changes in the user's athletic ability and physical condition. It is to provide an exercise support system and method capable of performing physical exercise.

  In order to achieve the above object, the present invention provides a sensor unit that is attached to a user and detects the vital information of the user, a user terminal used by the user, and a center connectable to the user terminal via a communication network. The center apparatus includes storage means for storing a plurality of exercise contents having different exercise loads. Then, based on the personal information including the user's exercise purpose, the exercise content suitable for the user is selected from the plurality of stored exercise content, and the selected exercise content is selected from the center device. Delivered to the user terminal and presented to the user. Also, during the user's exercise period, the user's vital information is received from the sensor unit, and the exercise amount of the user is calculated based on the received vital information. Then, it is determined whether or not the calculated amount of exercise is within the range of the target value set for the user, and it is determined that the calculated amount of exercise is not within the range of the target value. In this case, the presented exercise content is changed to another exercise content having a different exercise load.

  Therefore, according to the present invention, at the start of exercise, exercise content suitable for the user is selected and presented to the user based on personal information including the user's exercise purpose. For this reason, the user can exercise without relying on an instructor at a desired time zone at home, for example, taking into account his / her personal information, such as the purpose and sex of exercise, age, height weight, exercise history, etc. It becomes possible to start exercise according to optimal exercise content.

  Also, during the exercise period, the user's exercise amount is calculated based on the user's vital information, and if the exercise amount is not within the target value range, the exercise content being presented is changed to other exercise content with a different load. Be changed. For this reason, the exercise content with the optimal load is always presented according to the amount of exercise of the user, thereby correcting the excess or deficiency of exercise and performing exercise suitable for the purpose.

Further, according to the present invention, during the user's exercise period, the user's fatigue level is detected based on the user's vital information, and whether the detected fatigue level is within the allowable range set for the user. Determine whether or not. And as a result of this determination, when the detected fatigue level is not within the range of the allowable value, the presented exercise content is changed to another exercise content having a different exercise load. .
Therefore, exercise content is changed in consideration of not only the amount of exercise but also the physical condition and fatigue of the user during exercise. For this reason, the user can perform an exercise with an optimal load suitable for the physical condition and the fatigued state at that time.

Furthermore, the present invention estimates the value of vital data when the user feels comfortable for each purpose of exercise based on the past vital information during the user's calm or exercise. Then, it is determined whether the vital information of the user is within the range of the estimated value of the vital data when the user feels comfortable during the exercise period of the user, and the vital information is within the range of the estimated value. When not included, the presented exercise content is changed to another exercise content having a different exercise load.
Therefore, it becomes possible for the user to always perform an exercise with a load in which he / she feels comfortable, thereby further increasing his motivation to exercise.

Furthermore, the present invention is characterized in that after the exercise ends, at least one of the target value of the exercise amount and the allowable value of the fatigue level is variably set based on the vital information of the user.
In this way, it becomes possible to adaptively variably set at least one of the target value of momentum and the allowable value of fatigue according to the user's physical condition and fatigue state. The determination can be made more accurately.

Further, the present invention calculates the momentum of the user during or after the exercise, converts the calculated amount of exercise into a numerical value representing the degree of achievement based on the standard value of the amount of exercise according to the purpose of the exercise. A numerical value representing is shown to the user.
Therefore, the user can check the degree of achievement every time he / she exercises, and this can be expected to further improve the willingness to exercise.

  In short, in the present invention, based on personal information including the user's purpose of exercise, an exercise content suitable for the user is selected from a plurality of exercise contents having different exercise loads, and the selected exercise content is selected from the center. It is delivered from the device to the user terminal and presented to the user, and the user's vital information is received from the sensor unit during the user's exercise period, and the user's exercise amount is based on the received vital information. Is calculated. Then, it is determined whether or not the calculated amount of exercise is within the range of the target value set for the user, and when the calculated amount of exercise is not within the range of the target value, The presented athletic content is changed to another athletic content having a different exercise load.

  Therefore, according to the present invention, an exercise support system and method that can always present optimal exercise content according to changes in the exercise ability and physical condition of the user, thereby enabling the user to perform effective exercise without excess or deficiency. Can be provided.

  For example, as shown in FIG. 2, the sensor units SU <b> 1 to SUn are modularized by incorporating a heart rate sensor 11, a blood pressure sensor 12, an acceleration sensor 13, a communication circuit 14, and an antenna 15. The heartbeat sensor 11 detects a user's heartbeat or pulse. The blood pressure sensor 12 detects a user's blood pressure. The acceleration sensor 13 is used for detecting the amount of exercise of the user. The communication circuit 14 monitors the detection data of the heart rate sensor 11, the blood pressure sensor 12, and the acceleration sensor 13. When the value changes by a predetermined amount or more, the difference data from the detection data after the change or the detection data before the change. Is vital information. Then, the radio signal is modulated by this vital information and transmitted from the antenna 15.

The user terminals UT1 to UTn are made up of personal computers, for example, and have the following functions. FIG. 3 is a block diagram showing the configuration.
That is, the user terminals UT <b> 1 to UTn include a central processing unit (CPU) 21. A program memory 23 and a data memory 24 are connected to the CPU 21 via a bus 22, and a communication interface (communication I / F) 25, an input / output interface (input / output I / F) 26, and a sensor communication interface (sensor) Communication I / F) 30 is connected to each other.

The communication I / F 25 performs communication with the center apparatus CS according to a communication protocol defined by the communication network NW under the control of the CPU 21. For example, TCP / IP (Transmission Control Protocol / Internet Protocol) is used as the communication protocol.
An input unit 27 having a keyboard or the like, a display unit 28 such as an LCD, and a speaker 29 are connected to the input / output I / F 26. The input / output I / F 26 performs processing for capturing the data input at the input unit 27, displaying the display data on the display unit 28, and outputting audio data from the speaker 29.

  The sensor communication I / F 30 receives vital information transmitted from the sensor units SU1 to SUn associated with its own terminal via an antenna. As the wireless communication system, for example, a short-range data communication system such as BT (BlueTooth) (registered trademark) is used. In addition, as a means for receiving vital information, it is possible to use an infrared communication system, a wireless LAN communication system, or the like, and when using a mobile terminal as a user terminal, it is connected via a cable. May be.

The data memory 24 uses, for example, a hard disk, flash memory, RAM, or the like as a storage medium, and includes a personal information storage area 24a, a vital information storage area 24b, and an exercise content storage area 24c.
In the personal information storage area 24a, personal data of the user and data representing the purpose of exercise are stored. The personal data includes a user membership number and attribute information. Attribute information includes address, name, age, gender, occupation, family structure, height, weight, exercise history, medical history, diagnosis contents (high blood pressure, diabetes, etc.), preferences, comments, etc. as necessary. included. The data indicating the purpose of exercise is diet (weight down, partial thinness (feet, arms, waist, etc.)), muscular strength enhancement, exercise deficiency resolution (walking, jogging, stiffness of shoulders, low back pain, general gymnastics, etc.), refresh (whole body Relaxation exercise, elimination of desk work fatigue, etc.).

  In the vital information storage area 24b, vital information detected by the sensor units SU1 to SUn is sequentially accumulated together with the acquisition time. The vital information includes the heart rate or pulse rate, the blood pressure value, and the amount of user movement detected by the acceleration sensor 13 as described above.

  In the exercise content storage area 24c, exercise content data currently being executed or executed next is distributed from the center device CS. Note that exercise content data executed during a predetermined period such as the past week or one month may be stored as an exercise history.

The program memory 23 stores a personal information setting transmission control program 23a, a vital information acquisition / transmission control program 23b, an exercise amount determination program 23c, and an exercise content reception display control program 23d.
The personal information setting transmission control program 23a accepts input of personal data and data indicating the purpose of exercise by the user, and stores the input personal data and data indicating the purpose of exercise in the personal information storage area 24a. A process of transmitting from / F25 to the center device CS is executed. For example, a homepage disclosed on the Web is accessed by the center apparatus CS according to a user's operation, and personal data input by the user on the input screen of the homepage and data representing an exercise purpose are captured. In addition, prior membership registration is required to access the homepage, and the homepage can be accessed by inputting a user ID and password given from the center apparatus CS by this membership registration.

  The vital information acquisition / transmission control program 23b receives vital information transmitted from the sensor units SU1 to SUn by the sensor communication I / F 30 and stores the received vital information in the vital information storage area 24b. In response, a process of transmitting the vital information to the center apparatus CS is executed. Furthermore, the vital information memorize | stored in the said vital information storage area 24b is read, the display data represented by a graph or a numerical value is produced, and the process which displays this produced display data on the display part 28 is also performed.

  The exercise amount determination program 23c executes a process of determining the fatigue level and the amount of exercise of the user based on the personal data stored in the personal information storage area 24a and the vital information acquired from the sensor units SU1 to SUn. For example, a threshold value is set based on the age, sex, exercise history, and medical history of the user, and the degree of fatigue is determined by comparing the detected heart rate and blood pressure value with the threshold value. Further, the user's exercise amount is calculated based on the cumulative value of the amount of movement of each part of the body in a predetermined period detected by the acceleration sensor 13.

  The exercise amount determination program 23c sets a target exercise amount suitable for the user's exercise purpose based on the determination result of the fatigue level and the calculated value of the exercise amount. Then, it is determined whether or not the user's exercise amount is within an appropriate range by comparing the subsequent user's exercise amount with the target exercise amount. If the user's exercise amount is not within the appropriate range, the center device CS is requested to change the exercise load. Execute the process to send.

  The exercise content reception display control program 23d receives the exercise content data distributed from the center device CS through the communication I / F 25 and stores it in the exercise content storage area 24c. And according to the input of the exercise | movement start request | requirement by a user, the process which reads the said stored exercise content data from the said exercise content storage area 24c, and reproduces | regenerates it is performed. For example, if the athletic content includes video data and audio data, the video data is subjected to video decoding processing and then displayed on the display unit 28 by the input / output I / F 26, and the audio data is subjected to audio decoding processing and then input / output I / F. Output from the speaker 29 via F26.

On the other hand, the center device CS is constituted by a Web server and has the following functions. FIG. 4 is a block diagram showing the configuration.
That is, the center device CS includes a CPU 31. A program memory 33 and a data memory 34 are connected to the CPU 31 via a bus 32. Furthermore, a communication interface (communication I / F) 35, an input / output interface (input / output I / F) 36, and an external storage interface (external) Storage I / F) 39 are connected to each other.

  The communication I / F 35 communicates with the user terminals UT1 to UTn according to a communication protocol defined by the communication network NW under the control of the CPU 31. For example, TCP / IP (Transmission Control Protocol / Internet Protocol) is used as the communication protocol.

An input unit 37 including a keyboard and a display unit 38 such as an LCD are connected to the input / output I / F 36. The input unit 37 and the display unit 38 are used by an operator to update a server program and data and update exercise content.
The external storage I / F 39 is used to take in exercise content data separately edited and produced from an external storage medium such as a CD ROM, DVD, or memory card.

The data memory 34 uses, for example, a hard disk, flash memory, RAM, or the like as a storage medium, and includes an exercise content storage area 34a, a personal information storage area 34b, a vital information storage area 34c, and a premium information storage area 34d. ing.
The exercise content storage area 34a stores a plurality of exercise content data C1 to Ck prepared for distribution to the user terminals UT1 to UTn. Each of the exercise content data C1 to Ck is divided into a plurality of stages (m stages in the figure) in the time series direction as shown in FIG. 7, for example, and each stage has a plurality (j in the figure) having different exercise loads. A frame is available. For example, in the first stage, A frame 1 is the lightest movement, and the contents are edited so that the heavy movement can be gradually performed as the number increases like A frame 2, A frame 3,. Frames are prepared. Note that end content is prepared after the m-th stage.

  The personal information storage area 34b stores user personal information sent from the user terminals UT1 to UTn. As described in the user terminals UT1 to UTn, the personal information is composed of the user's personal data and data representing the exercise purpose. The personal information storage area 34b also stores identification codes of exercise content data distributed in the past for each user.

In the vital information storage area 34c, vital information for a predetermined past period sent from the user terminals UT1 to UTn is stored in association with the personal information of each user.
In the prize information storage area 34d, item data of prizes that can be exchanged according to points (points) acquired according to the amount of exercise by the user is stored. Examples of prizes include sports towels and bags, sportswear, shoes, and supplements. Conversion to mileage points or the like is included as part of the prize.

The program memory 33 stores a user information reception storage control program 33a, an exercise content selection control program 33b, an exercise quantity score management program 33c, and an exercise content distribution control program 33d.
The user information reception storage control program 33a receives user personal information and vital information by communicating with the user terminals UT1 to UTn through the communication I / F 35, and receives the received personal information in the personal information storage area 34b. In addition, processing for storing vital information in the vital information storage area 34c is executed.

  The exercise content selection control program 33b selects exercise content with an optimal load for each user based on the personal information of the user, that is, data representing personal data and exercise purpose, and vital information at the start of exercise. Further, when an exercise load change request is sent from the user terminals UT1 to UTn during the exercise period, the exercise content frame in use is switched to another frame having a different load according to the content of the change request.

  The momentum point management program 33c replaces the amount of exercise performed by the user with points indicating points of achievement, and the amount of exercise set in association with each purpose of the exercise and each frame of the exercise content data used for the exercise. In consideration of the standard value of calorie consumption, a process of converting the user's exercise amount sent from the user terminals UT1 to UTn into points is executed.

  The exercise content distribution control program 33d is a user corresponding to the communication I / F 35 for the frame of the exercise content data selected or changed by the exercise content selection control program 33b before or during the exercise start for each user. Transmit to terminals UT1 to UTn.

  Next, the operation of the exercise support system configured as described above will be described. 5 and 6 are flowcharts showing control procedures and control contents of the user terminals UT1 to UTn and the center apparatus CS.

  The center device CS publishes a homepage for guiding the provision of the exercise support service on the Web in step S1. On this homepage, explanations of membership recruitment guidelines, contents of available exercises, etc. are presented. For example, when a training recommendation group such as a sports club or a fitness club operates the center apparatus CS, a plurality of types of exercise content are prepared in advance for various purposes expected by the user. As the purpose of exercise, there are “diet purpose”, “health maintenance purpose”, “exercise lack elimination purpose”, “muscular strength enhancement purpose” and the like. The exercise content data corresponding to these purposes is stored in advance in the exercise content storage area 34a of the center device CS. Further, in step S2, the center device CS stores reference values such as a heart rate, blood pressure, and body temperature based on a general person's age, sex, occupation, and the like. The reference value of this vital data is used to determine the basic state of the user's physical condition.

  On the other hand, when using the exercise support service, it is assumed that the user performs an operation for opening a corresponding homepage on the Web at his / her user terminal (for example, UT1). Then, the CPU 21 of the user terminal UT1 activates the browser function in step S3 to access the home page, downloads the display data, and displays it on the display unit 28. In this state, if the user performs an input operation for member registration on the member registration page, the CPU 21 stores personal data such as the user's name, address, age, and gender input in step S4, and data indicating the purpose of exercise. , And these data are transmitted from the communication I / F 25 to the center apparatus CS in step S5.

  On the other hand, when the center apparatus CS receives input data for member registration from the user terminal UT1 in step S6, the center apparatus CS issues a user ID and a password to the user who has requested registration in step S7a and sends it to the user terminal UT1. Send. The received personal data and exercise purpose data are stored in the personal information storage area 34b in the data memory 34 in step S8. The user terminal UT1 receives and stores the user ID and password sent from the center device CS in step S7b. Thus, after that, the user can use the exercise support service by the system.

  When exercising using the exercise support service, the user registers his / her vital information prior to starting the exercise. For example, the user attaches the sensor unit SU1 to his / her body and activates his / her user terminal UT1 in the early morning period, before going to bed, or during a time when he / she does not exercise. Then, the sensor unit SU1 detects the user's heart rate, blood pressure value, and amount of movement by the acceleration sensor 13 (step S9), and these detected data are transmitted as vital information from the communication circuit 14 to the user terminal UT1 in step S10. Is done.

  The user terminal UT1 receives the vital information in step S11, saves the received vital information in the vital information storage area 24b, and transmits it to the center apparatus CS from the communication I / F 25. When the center device CS receives vital information from the user terminal UT1 in step S12, the center device CS stores the received vital information in the vital information storage area 34c of the data memory 34.

  Now, let us assume that the user inputs an exercise start request in this state. When the user terminal UT1 receives the exercise start request in step S13, the user terminal UT1 transmits the request to the center device CS. Upon receiving the exercise start request, the CPU 31 of the center device CS selects exercise content suitable for the requesting user in step S14. This exercise content is selected based on the user's exercise purpose, personal data, and normal vital information registered in advance.

  For example, if the user sets the exercise purpose to “diet”, the age, sex, current weight, etc. included in the personal data and vital information, and the subject of relatively light whole body exercise or partial thinning to last long Select the exercise content to move the part. If the exercise purpose is “muscle strength enhancement”, exercise content that is intense to some extent is selected based on personal data and vital information.

  When the selection of the exercise content is completed, the user terminal UT1 reads the selected exercise content data from the exercise content storage area 34a in step S15 and distributes the exercise content data to the user terminal UT1. At this time, if the unit of the exercise content to be distributed is, for example, the content data C1 shown in FIG. 7, the frame is selected one by one in each stage from the first stage to the m-th stage and the end content. Note that only the first-stage frame may be distributed without distributing all the frames of all stages.

  The user terminal UT1 receives the exercise content data C1 in step S16 and stores it in the exercise content storage area 24c. Then, the exercise content C1 is reproduced in step S17. As a result, if the exercise content C1 is composed of instructor video data and audio data, the instructor video is displayed on the display unit 28 in the user terminal UT1, and at the same time, audio or music is output from the speaker 29. . The user moves his / her body while watching the video of the instructor and in accordance with voice or music.

  When the user's exercise is started, the heart rate, the blood pressure value, and the amount of movement are detected in step S18 in each of the sensors 11 to 13 of the sensor unit SU1 attached to the user, and the amount of change becomes a predetermined amount. If it exceeds, the detection data of each sensor will be transmitted to the user terminal UT1 from the communication circuit 14 as vital information by step S19. Upon receiving the vital information, the user terminal UT1 saves the received vital information in the vital information storage area 24b in step S20, and then transmits the vital information to the center device CS from the communication I / F 25. At the same time, the user terminal UT1 converts the received vital information into a form that can be confirmed at a glance by the user during exercise at step S21, for example, a numerical value or a graph, and the converted vital data is an image of the exercise content data C1. Is displayed on the display unit 28. Therefore, the user can confirm the change of his / her vital data while viewing the video of the exercise content data C1.

Furthermore, the user terminal UT1 determines whether or not the user's exercise amount is an appropriate amount in step S22 based on the received vital information. This determination is performed by the exercise amount determination program 23c as follows.
That is, by first setting a determination threshold value based on the age, sex, exercise history, and medical history included in the user's personal data, and comparing the detected heart rate and blood pressure value with the determination threshold value. Determine the degree of fatigue. Further, the user's exercise amount is calculated based on the cumulative value of the amount of movement of each part of the body in a predetermined period detected by the acceleration sensor 13. Next, a target exercise amount suitable for the purpose of the user's exercise is set based on the determination result of the fatigue level and the calculated value of the exercise amount. Then, it is determined whether or not the user's exercise amount is within an appropriate range by comparing the subsequent user's exercise amount with the target exercise amount.

  For example, if the purpose of the exercise is diet, assuming that it is necessary to further consume about 700 kcalories in addition to the normal one-day exercise, it is desirable to consume 116 kcalories in 10 minutes for one hour of exercise. . Therefore, the upper limit value and the lower limit value are set as threshold values based on the desired consumption. For example, if it is appropriate that both the upper limit value and the lower limit value are within 10%, the upper limit value is set to 127 kcalories and the lower limit value is set to 106 kcalories.

  Then, it is determined whether or not the user's exercise amount (calorie consumption) calculated based on the vital information is within a range defined by the upper limit value and the lower limit value. It is determined that On the other hand, when the user's exercise amount is out of the range defined by the upper limit value and the lower limit value, the user's exercise amount is not an appropriate amount. Therefore, an exercise load change request is sent from the communication I / F 25 to the center in step S23. Transmit to device CS.

  The center device CS monitors the arrival of the vital information from the user terminal UT1 and the arrival of the exercise load change request while monitoring the end of the frame of the exercise content data C1 currently being reproduced by the user terminal UT1 in step S26. Monitoring is performed at S24 and step S25. In this state, it is assumed that a request for changing vital information and exercise load has arrived from the user terminal UT1. Then, the center apparatus CS proceeds to step S27 after the end of the exercise content frame C1 currently being reproduced, and here, the exercise content frame to be used in the next stage according to the contents of the change request is changed to another frame having a different load. The process for switching to is executed.

  For example, assume that the user terminal UT1 is playing the A frame 3 at the first stage of the exercise content data C1 shown in FIG. In this state, if an exercise load change request arrives from the user terminal UT1, and the content changes to a light load, the center device CS uses it in the next second stage in response to this request. The power frame is changed from the B frame 3 to the B frame 2 having a lighter load than that. Then, the data of the B frame 2 after the change is distributed from the communication I / F 35 to the user terminal UT1 in step S28.

  On the other hand, if the content of the exercise load change request coming from the user terminal UT1 is to change the load to a heavier load, the center device CS responds to this request with a frame to be used in the next second stage. Is changed from B frame 3 to B frame 4 with a heavier load than that. Then, the data of the B frame 4 after the change is distributed from the communication I / F 35 to the user terminal UT1 in step S28.

  When receiving the changed frame data from the center apparatus CS in step S29, the user terminal UT1 reproduces the received changed frame in the next second stage. Therefore, in the second stage, the user can continue exercising according to the frame changed according to the change of his / her vital information in the first stage.

  For example, if the user's physical condition is bad on this day and the exercise load in the first stage is too intense for the user, the reproduced frame is automatically changed to a frame with a light exercise load in the second stage. For this reason, the user can continue the light exercise according to the physical condition of this day without overdoing it. On the other hand, if the user's physical condition is good and the first stage exercise load is unsatisfactory for the user, the frame reproduced in the second stage is automatically changed to a frame with a heavy exercise load. For this reason, the user can perform a slightly heavier exercise according to the physical condition of the day, and can feel comfort.

  Thereafter, similarly, the user terminal UT1 determines whether or not the user's exercise amount is appropriate for each stage of the exercise content distributed from the center device CS. If it is not appropriate, an exercise load change request is sent from the user terminal UT1 to the center. It is sent to the device CS, and the next frame change is performed.

  In step S30, the user terminal UT1 monitors the end of the reproduction of the exercise content data C1, and when the end is detected, the user terminal UT1 transmits an exercise end notification to the center device CS in step S31. When the center apparatus CS receives the exercise end notification from the user terminal UT1 in step S32, the center apparatus CS proceeds to step S33, where the exercise amount or calorie consumption received from the user terminal UT1 during the exercise period based on the exercise content data C1 is calculated. Converted into points that represent a sense of accomplishment. This conversion processing is performed in consideration of the purpose of exercise and the amount of exercise or the standard value of calorie consumption in each frame of the exercise content data C1 used for exercise. Then, the score obtained by this conversion process is stored in the data memory 34 in step S34.

  The following can be considered as an example of the scoring process. That is, if the calorie consumption of the exercise by one frame is 69k calorie, the 73k calorie is 100 points when the reference value is 73k calorie, so the score of the user is 95 points. This calculation process is executed for each frame, and the average value is defined as the number of points acquired on that day.

  As another example of the scoring process, the following can be considered. That is, if the total value of calories consumed at all stages (from start to finish) of the exercise content is 638 kcalories, if the target value is 700 kcalories, it is 100 points at 700 kcalories, so the user's score is 91 It becomes a point. In other words, calories consumed through all stages of athletic content are converted into points. In addition, in order to eliminate the variation in the number of points due to the purpose of training, 100 points are calculated when the target value is close to the target value with a predetermined width, and the points are reduced based on the vertical width when the target value is raised or lowered. May be.

  On the other hand, if “health enhancement” or “physical strength enhancement” was the purpose of exercise, calorie consumption does not simply lead to a sense of achievement of exercise, so it is necessary to convert the amount of exercise according to the purpose of exercise into points . For this purpose, “comfort” is used as an objective variable, and vital information such as “heart rate”, “blood pressure value”, and “motion amount” is used as an explanatory variable, and calculation is performed by a multiple regression analysis technique.

  8 and 9 are diagrams used for explanation for predicting “comfort” due to moderate fatigue during “health enhancement” and “physical strength enhancement”. FIG. 8 is a graph showing fatigue feeling over time based on vital information, and FIG. 9 predicts optimal health promotion and physical strength enhancement values from the standard values of vital information and the individual vital measurement values. It is the figure which showed the numerical value for doing. That is, it is a figure which shows the analysis data by a multiple regression analysis method.

  According to the graph of FIG. 8, when a user exercises with exercise content recommended by the system for maintaining health, for example, the user's vital information changes depending on the exercise status. For example, when the user moves his arms and legs during training, vital information such as heart rate, blood pressure, and amount of movement changes, and the user feels tired. Whether this feeling of fatigue is comfortable for the user, or unsatisfactory or painful is predicted by multiple regression analysis.

  In FIG. 9, first, a reference value is set based on a user's vital value. The target variable is health maintenance Y, the explanatory variables as reference values are heart rate X1, exercise amount X2, and blood pressure X3, and the explanatory variables of the measured values when the number of samples is 3 are heart rates C11, C21, C31, and exercise amount C12. , C22, C32, blood pressure C13, C23, C33, further, the error is e, and the partial regression coefficients are a0 to a3, the regression model is expressed by the following equation (Equation 1).

なる連立方程式が得られる。 Substituting the measured values C11 to C13, C21 to C23, and C32 to C33 into Equation 1,

The following simultaneous equations are obtained.

Subsequently, the simultaneous equations of Equation 2 are solved by the following equation so that the residual sum of squares (SSE) is minimized, and the partial regression coefficients (a0 to a3) are obtained by the least square method.

The smaller the SSE (residual sum of squares) is, the better the fit of the regression model is, and the square of the determination coefficient R is defined by Equation 5.

  Therefore, 0 <= R2 <= 1, and the closer R2 is to 1, the better the fit, and the square root of the determination coefficient matches the multiple correlation coefficient. That is, a prediction value is acquired about a user's factor (heart rate, exercise amount, blood pressure). This predicted value is a value representing a feeling of fatigue that is comfortable for the user. If the measured vital information is the same as this predicted value, the predicted value is 100 points. On the other hand, when it is unsatisfactory or too intense, only the difference is subtracted. This calculated score is stored in the user's personal data as in the case of the diet and the like.

  Further, the center device CS compares the calculated predicted values of the user's heart rate, exercise amount, and blood pressure with a reference value (target value) of comfort, and thereby the predicted value is within the range set as the reference value. Determine whether to enter. When the predicted value does not fall within the range of the reference value, the exercise content selection control program 33b reselects the exercise content most suitable for the user and distributes the selected exercise content data to the user terminal UT1. In the user terminal UT1, the delivered exercise content data is reproduced thereafter, and the user exercises according to the reproduced exercise content.

  Each time the exercise of the day ends, the center device CS transmits the calculated score and the total value of the score in the past predetermined period (for example, one week or one month) to the user terminal UT1 of the corresponding user. To do. The user terminal UT1 stores in the data memory 23 the total value of the sent points for the day and the points for the past predetermined period, and displays them on the display unit 28. Therefore, the user can also realize the feeling of achievement by exercise by numerical values by confirming the number of points displayed after the end of exercise and the total value of the predetermined period.

  In addition, the user can exchange the points acquired by the user by accessing the homepage of the center apparatus CS from his / her user terminal UT1 and searching for information on the gift list. In this process, the user terminal UT1 sends to the center apparatus CS information specifying the exchange target prize together with the exchange request, and the request stored in the data memory 34 and the prize designated by the center apparatus CS in response to the exchange request. The number of points obtained by the original user is checked, and if exchange is possible, the gift delivery procedure is performed by instructing delivery to a delivery center (not shown).

  The score converted based on the amount of exercise may be displayed after the reproduction of the exercise content as described above, but may be displayed every time the reproduction of one frame is completed. Prior to the start of exercise, a score corresponding to the target exercise amount is set, and when one piece of exercise content has been reproduced or one frame has been reproduced, the number of points until the goal is achieved is calculated. The calculated score may be transmitted to the user terminal UT1 for display.

  As described above, in this embodiment, the user's exercise purpose and personal data are sent from the user terminals UT1 to UTn to the center apparatus CS, and exercise content data suitable for the user is stored in advance based on these data. It selects from among a plurality of exercise contents and distributes it to the user terminals UT1 to UTn. And during the period when the user is exercising using the delivered exercise content, the user terminal UT1 to UTn receives the user's vital information from the sensor units SU1 to SUn, and the received vital information is received. The amount of exercise of the user is calculated based on the above, and it is determined whether or not the calculated amount of exercise is within the target value range. When it is determined that the calculated amount of exercise is not within the range of the target value, an exercise load change request is sent from the user terminals UT1 to UTn to the center device CS, and the center device CS responds to the request. Accordingly, the frame of the exercise content data is changed and distributed.

  Therefore, at the start of exercise, first, exercise content suitable for the user is selected and presented to the user based on the user's exercise purpose and personal data. For this reason, the user can exercise without relying on an instructor at a desired time zone at home, for example, taking into account his / her personal information, such as the purpose and sex of exercise, age, height weight, exercise history, etc. It becomes possible to start exercise according to optimal exercise content.

  Also, during the exercise period, the user's exercise amount is calculated based on the user's vital information, and if the exercise amount is not within the target value range, the displayed exercise content is changed to other exercise content with a different load. Automatically changed. For this reason, the exercise content with the optimal load is always displayed according to the amount of exercise of the user, thereby correcting the excess or deficiency of exercise and performing exercise suitable for the purpose.

  Further, in the center device CS, the calculated predicted values of the heart rate, exercise amount and blood pressure of the user are compared with a reference value (target value) of comfort, whereby the predicted value is within the range set as the reference value. Determine whether to enter. When the predicted value does not fall within the range of the reference value, the exercise content optimum for the user is selected again and distributed to the user terminal UT1. Therefore, it becomes possible for the user to always perform an exercise with a load in which he / she feels comfortable, thereby further increasing his motivation to exercise.

Further, every time the exercise of the day is completed, the converted score corresponding to the amount of exercise and the total value of the score in the past predetermined period (for example, one week or one month) are displayed on the user terminal UT1 of the corresponding user. I have to. For this reason, the user can also realize the feeling of achievement by exercise by numerical values by checking the score displayed after the exercise is completed and the total value of the predetermined period. Further, since the exchange with the prize is made possible, there is an advantage that a goal can be made in addition to the exercise itself, and the user can continue training.
Furthermore, the user can input and set the purpose of exercise before daily training. For this reason, it becomes possible to select the optimal exercise content according to the mood at that time, the physical condition of the day, or the degree of fatigue for every exercise.

The present invention is not limited to the above embodiment. For example, in the embodiment, the exercise amount of the user is calculated based on the vital information of the user during the exercise period, and the frame of the exercise content is changed when the exercise amount is not within the target value range. . However, the present invention is not limited to this, and the user's fatigue level is detected during the exercise period based on the user's vital information, and whether or not the detected fatigue level is within the range of allowable values set for the user. Determine. Then, as a result of this determination, when the detected fatigue level is not within the range of the allowable value, the presented exercise content may be changed to another exercise content having a different exercise load. .
In this way, exercise content is changed in consideration of not only the amount of exercise but also the fatigue level of the user during exercise. For this reason, the user can perform an exercise with an optimal load suitable for the physical condition and the fatigued state at that time.

  Further, the target value of the exercise amount and the allowable value of the fatigue level may be variably set based on the vital information of the user. In this way, it becomes possible to adaptively variably set the target value of the momentum and the allowable value of the fatigue level according to the user's physical condition and fatigue state, thereby further determining the user's momentum and the fatigue level. It is possible to perform accurately.

  Furthermore, in the above embodiment, one exercise content is divided into a plurality of stages, and a frame having a load suitable for the user is selected and changed from the plurality of frames for each stage. However, the present invention is not limited to this, and it may be selected and changed in units of exercise content. In the embodiment, the frame changing process is performed at the timing when the stage is switched. However, the frame may be changed during the stage.

  Furthermore, as a device for displaying athletic content, a stationary display device using a CRT or a liquid crystal may be used. However, when a user lays down and performs stretching exercises, exercise while observing the display device while maintaining a predetermined pose. Therefore, a head-mounted display device may be used. In addition, the shape and size of the display device are not particularly limited.

In addition, the system configuration, the configuration of the user terminal and the center device, the procedure and contents of exercise support control, and the like can be variously modified without departing from the scope of the present invention.
In short, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment.
