Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heartbeat measuring device with a calorimeter, which simultaneously displays the measured heart rate and consumed calories.

[0002]

2. Description of the Related Art Considering current health, it is important from the viewpoint of preventive medicine to maintain a balance between calories consumed by humans by food and consumed by their daily lives. is there.

However, the amount of calorie consumption in human daily life is decreasing due to the current development of transportation facilities. On the other hand, the calorie intake by food is not decreasing but rather increasing, and the balance between calorie consumption and intake is becoming unbalanced. For this reason, it is important to actively exercise and increase calorie consumption,
The number of people exercising is increasing.

Considering this exercise, it is important for each individual to make an exercise menu from the standpoint of calorie consumption and manage it based on it, instead of doing it appropriately.

From this point of view, conventionally, there have been the following methods for calculating the calorie consumption by the exercise of each individual.

(1) Oxygen consumption is directly measured by an oxygen consumption measuring device, and this measured value is converted into calorie consumption.

(2) A heart rate and oxygen consumption are measured by an exercise load test or the like to calculate a correlation straight line with the calorie consumption, and the measured heart rate is substituted for this.

(3) The calorie consumption is calculated from a publicly available table in which how many calories are consumed by performing a certain exercise.

(4) As in the technique described in Japanese Patent Laid-Open No. 54-160280, only one typical correlation line is determined, and based on this, the heart rate is measured and the calorie consumption is calculated at the same time.

[0010]

However, the above-mentioned respective prior arts have the following problems.

(1) In the above methods (1) and (2),
Although the measured values are accurate, expensive measuring equipment and specialized knowledge are required, and the amount of exercise, type of exercise, etc. are regulated,
It is very difficult for an individual to use it on a daily basis.

(2) In the method of (3), since the type, method, and time of exercise are accurately managed, the degree of freedom for exercise is regulated, and the exercise performed by an individual in daily life is regulated. It has a strong feeling and does not fit.

(3) Furthermore, in the method of (4), since there is only one correlation straight line, when many subjects are measured and surveyed, the measured values may be greatly deviated due to individual differences (sex, physical strength, etc.). There is. That is, even if the same measured heart rate is used, the calorie consumption per unit weight may differ from the maximum to the minimum by three times or more due to individual differences, and there is a large error in calculating only one correlation line. It is too good for practical use.

The present invention has been made in view of the above problems, requires no specialized knowledge and complicated and expensive measuring equipment, is simple, and has less physical strength (maximum oxygen uptake capacity) of each individual. An object of the present invention is to provide a heartbeat measuring device with a calorimeter, which can calculate calorie consumption as an optimum approximate value for various exercises due to an error.

[0015]

In order to solve the above problems, the present invention obtains calorie consumption from measured heart rate,
In a heart rate measuring device with a calorimeter that displays calorie consumption as well as heart rate, it is a correlation line set by statistically analyzing the relationship between heart rate and calorie consumption with individual differences, and it is approximate to an unspecified number of individuals Correlation that selects the most suitable correlation line for the individual from the storage means that stores a plurality of correlation straight lines that can be adaptively stored and the plurality of correlation straight lines that are stored in this storage means by matching with the input personal information It is characterized by comprising straight line selecting means and calorie calculating means for calculating the calorie consumption corresponding to the measured heart rate based on the correlation straight line selected by the correlation straight line selecting means.

[0016]

The correlation straight line selecting means selects the optimum correlation straight line for the subject from the plurality of correlation straight lines stored in the storage means, and the calorie calculating means calculates the consumed calories corresponding to the heart rate based on the correlation straight line. , Display calories burned with heart rate.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

The heart rate measuring device with a calorimeter according to the present embodiment statistically analyzes the relationship between the heart rate and the calorie consumption which differ among individuals, and sets a plurality of correlation straight lines which can be adapted to an unspecified number of individuals. Then, an optimum correlation straight line for each individual is selected from the set plurality of correlation straight lines, and calorie consumption is calculated and displayed based on the selected correlation straight line.

Specifically, by an experiment conducted on a large number of people with different physical strengths, the correlation between heart rate and calorie consumption (converted from maximum oxygen intake) was detected and statistically analyzed. , A plurality of average correlation lines are obtained so that the correlation lines of individuals are within a certain error range. Note that this correlation line becomes a straight line.

Further, as means for selecting a correlation line close to the characteristics of an individual from among the plurality of correlation lines,
Refer to the following personal information.

(1) Resting heart rate (2) Score of question form (3) Numerical value of exercise test The relationship between these three pieces of information (details will be described later) of each individual and the plurality of correlation straight lines is statistically calculated. Then, it is set in advance so that a specific correlation straight line is selected for specific values of these numerical values. In addition, the basic energy consumption determined by age, sex, weight, etc. is also considered.

The personal information (1), (2),
Any one or more of (3), and the age, sex, and weight of the subject are input to the measuring device. With these input values, select a correlation line that is close to the correlation line specific to the subject, calculate the calorie consumption of the individual from the measured heart rate based on this correlation line, and at the same time as the heart rate, It displays the calorie consumption of.

Next, a specific configuration of the heartbeat measuring device with a calorimeter will be described.

FIG. 1 is a block diagram showing the overall configuration of a heart rate measuring device with a calorimeter, and FIG. 2 shows a state in which an exerciser (measured person) has attached the heart rate measuring device with a calorimeter to the body. FIG. 3 is a perspective view showing the heart rate display device.

This heart rate measuring device with a calorimeter is shown in FIG.
As shown in FIG. 2, the heart rate detector 1 and the heart rate display device 5 are mainly included.

The heartbeat detector 1 includes a band 2 wound around the body of the person to be measured, a pair of heartbeat detection electrodes 3 attached to the band 2 for detecting the heart rate, and a heartbeat signal detected by the electrodes 3 It is composed of a transmitter 4 for transmitting to the display device 5.

The heartbeat display device 5 mainly includes a receiver 6 that receives a weak electric wave of the heartbeat signal transmitted from the transmitter 4 of the heartbeat detector 1, and a heartbeat detection circuit 7 that detects the heartbeat from the received signal. And a calorie consumption calculation unit 8 for calculating calorie consumption from the received heart rate, and a display 9 for displaying the heart rate detected by the heart rate detection circuit 7 and the calorie consumption calculated by the calorie consumption calculation unit 8. It consists of and. This heart rate display device 5 is attached to the wrist with a band 10.

The calorie consumption calculation unit 8 is connected to a condition value input switch 12 for inputting condition values regarding various individuals, and is connected to each of the condition value input switches 12 and has a certain condition (corresponding to the inputted personal information). The first to third selection circuits 1 for selecting which of the logic storage circuits 16 to 20 to be activated, which will be described later, under this condition) will be described.
3, 14, 15 and a plurality of correlation lines that can be approximately applied to an unspecified large number of individuals set by statistically analyzing the relationship between heart rate and calorie consumption with individual differences are stored as logical expressions. First to fifth logic memory circuits 16 as memory means
20 and the logic storage circuit 16 by the selection circuits 13 to 15
Based on the comparison circuit 21 that specifies one logical storage circuit by comparing them when a plurality of .about.20 are selected and one circuit (correlation line) specified by this comparison circuit 21, the heartbeat detector 1 And a calorie calculating circuit 22 as a calorie calculating means for calculating calorie consumption from the detected heart rate. The selection circuit 13-
15 and the comparison circuit 21 constitute a correlation line selection means. Further, each logical storage circuit 16 to 20 has 1
Logical formulas (correlation lines) are stored for each.

As shown in FIG. 3, the condition value input switch 12 is composed of switches arranged on the surface of the heartbeat display device 5 together with the display 9. Specifically, set value input mode switch 25, age, resting heart rate,
It includes a setting item changeover switch 26 for selecting and switching items such as weight and sex, and a numerical value setting switch 27 for inputting numerical values of the selected items. Reference numeral 28 is a power switch of the heartbeat display device 5.

Next, the specific processing contents of the selection circuits 13 to 15, each of the logic storage circuits 16 to 20 and the comparison circuit 21 will be described.

The correlation straight line are respectively stored in the logical storage circuits 16 to 20 each logical storage circuits 16 to 20 is obtained as follows.

This correlation straight line is a straight line obtained by statistically estimating and calculating the population, and the measured values of a large number of subjects are statistically analyzed and divided into a plurality of populations according to the analysis result, and each individual is divided. The average correlation line approximated to each of the correlation lines is calculated.

First, the maximum oxygen uptake amount per 1 kg of body weight of each subject was obtained by an experiment, and this was divided into five evaluation groups as physical strength values (maximum oxygen uptake ability). The population of each group is statistically analyzed and the average regression line is obtained. This regression line obtained by the experiment is shown in FIG. In addition, FIG. 4 is a numerical value in the case of a man. Since there is a difference in physical strength between men and women, the regression line is calculated separately for men and women.

Further, this straight line is expressed by the following equation.

Evaluation 1 y = b1 + a1 * x Evaluation 2 y = b2 + a2 * x Evaluation 3 y = b3 + a3 * x Evaluation 4 y = b4 + a4 * x Evaluation 5 y = b5 + a5 * x y: Oxygen consumption x: Heart rate a1 to a5 : Constant b1 ~
b5: constant Here, b1 ... b5 correspond to the intercept of the first-order straight line, and this value is considered to be b1 = b2 = b3 = b4 = b5 in the population. Since there is no problematic error, b1 = b2 = b3 = b4
= B5.

Therefore, the difference in the physical strength (maximum oxygen uptake ability) of each individual becomes prominent depending on the slopes a1 to a5 of the linear line. Further, as the inclinations a1 to a5 increase, the physical strength (maximum oxygen intake capacity) increases.

Here, evaluation is made in order from the one having the largest physical strength.
> Evaluation 4> Evaluation 3> Evaluation 2> Evaluation 1

Then, the above five theoretical lines (theoretical formulas)
Is stored in advance in each of the logic storage circuits 16 to 20. That is, the theoretical line of evaluation 1 is stored in the first theoretical memory circuit 16, the theoretical line of evaluation 2 is stored in the second theoretical memory circuit 17, the theoretical line of evaluation 3 is stored in the third theoretical memory circuit 18, and the theoretical line of evaluation 4 is stored. The fifth theoretical memory circuit 20 stores the theoretical straight line of the evaluation 5 in the fourth theoretical memory circuit 19, respectively.

When the subjects are divided into the above-mentioned five grades and the number of subjects at any stage is too small to obtain statistics at that stage, the assessment value is calculated as follows. .. Here, it is assumed that the statistical value of evaluation 1 could not be obtained.

The resting heart rate of the subjects in the groups of evaluations 2 to 5 was averaged, and the average value and the slope a of each correlation line
When the relationship with is examined, it becomes as shown in FIG. As can be seen from this figure, the relationship between the average rest heart rate and the slope a of each correlation line is best represented by the quadratic curve shown. Quadratic equation representing the quadratic curve ^{a = d1 * c 2 + d2} * c + d3 a: is a constant: gradient c: resting heart rate d1, d2, d3.

From this equation, the value of evaluation 1 and the value of resting heart rate corresponding thereto are obtained. Specifically, at points F5 to F2 corresponding to evaluations 5-2 on the quadratic curve in FIG.
The distance between 5 and F4, the distance between F4 and F3, and the distance between F3 and F2
The point F1 of the evaluation 1 is obtained in consideration of the interval between and. For example,
An average value of these intervals is calculated, and a position deviated from F2 on the quadratic curve by the average value is defined as F1. As a result, the value of Evaluation 1 is obtained. This is the same when other statistical values of evaluations 2 to 5 are not obtained.

First Selection Circuit 13 The first selection circuit 13 carries out the following processing. That is, the relationship between the resting heart rate and the slopes a1 to a5 is determined.

The slopes a1 to a5, that is, the evaluations 1 to 5 are made to correspond to the widths of the resting heart rate p below.

Evaluation 1 p1 or more Evaluation 2 p2 to less than p1 Evaluation 3 p3 to less than p2 Evaluation 4 p4 to less than p3 Evaluation 5 p4 or less Note that p1 to p4 are set as follows. That is, in the graph of FIG. 4, the intermediate value of the heart rate of the evaluation 1 and the evaluation 2 at the oxygen consumption of 5.5332 ml / min · Kg (resting heart rate) is p.
1, the intermediate value between the evaluations 2 and 3 is p2, the intermediate value between the evaluations 3 and 4 is p3, and the intermediate value between the evaluations 4 and 5 is p4.

The resting heart rate is p1>p2> p3.
> P4 order. That is, the higher the heart rate, the smaller the physical strength (maximum oxygen uptake capacity) and the lower the evaluation. This relationship differs depending on the gender, so we ask for it separately for men and women.

The above conditions are stored in the first selection circuit 13, and the evaluation value is determined by the resting heart rate and the like inputted. For actual use, the sex, weight, and resting heart rate are input by the condition value input switch 12. The first selection circuit 13 selects the correlation straight line closest to the correlation straight line of the subject based on the input sex or the like, and one of the logic storage circuits 16 to 2 is selected.
Specify 0.

The values of p1 to p4 may be set using the graph of FIG. That is, on the quadratic curve of this graph, the points F1, F2, F corresponding to each evaluation are
It may be an intermediate point between 3, F4 and F5.

Second selection circuit 14 The second selection circuit 14 performs the following processing. That is, the relationship between the score and the slopes a1 to a5 in the question form is determined.

The behavior of the subject in his or her daily life determines the maximum oxygen uptake of the individual. People with low maximal oxygen uptake will improve their abilities with continuous training and will be able to get more oxygen with a lower heart rate. On the other hand, when athletes retire from active exercise and rest for a long period of time, maximum oxygen intake decreases. That is, the maximum oxygen intake of the person is almost determined by exercise in life.

This means that by investigating the exercise life in a question form, this can be used as a score to select the slopes a1 to a5.

An example of this question format is shown below.

1. How much exercise do you do for commuting and shopping? Walk: minutes, how many times / week Bicycle: minutes, how many times / week 2. Do you currently do any exercise? Kind of exercise, minutes, how many times / week 3. ...... Ask about 10 questions about oxygen consumption as above, and calculate the score based on the answers. The second selection circuit 14 records the relationship between the score obtained by the subject, the weight of the subject, the sex, and the oxygen consumption of the subject actually examined.

As a result, the subject inputs the weight and sex from the condition value input switch 12 and answers the question, thereby determining the oxygen consumption amount from the acquired points.
Then, the theoretical formula is specified from the oxygen consumption amount, and the correlation line adapted to each individual is called from each of the logical storage circuits 16 to 20.

Third Selection Circuit 15 The third selection circuit 15 performs the following processing. That is, the relationship between the numerical value of the exercise test and the inclinations a1 to a5 is determined.

The exercise test is performed by the Harvard step test which is open to the public.

This test requires the subject to test 20 inches (5
(0.8 cm) platform is moved up and down at a tempo of 30 times per minute for 5 minutes, and physical fitness is evaluated from the post-exercise recovery heart rate and exercise duration.

The subject moves up and down the platform once every 2 seconds for 5 minutes in accordance with the rhythm of the metronome, for example. Then, the pulse rate is measured three times from 1 minute to 1 minute 30 seconds, 2 minutes to 2 minutes 30 seconds, and 3 minutes to 3 minutes 30 seconds after the exercise. If the exercise is interrupted midway, the time is immediately recorded and the pulse rate after the exercise is measured in the same manner as described above.

Based on the measured value, the physical strength index is calculated by the following formula.

Physical fitness index = {exercise duration (seconds) × 10
0} / {2 × (total of 3 pulse rates)} This expression gives the score of each subject. The obtained scores of each subject are statistically calculated and divided into 5 grades according to the following evaluation criteria.

55 or less Evaluation 1 55 to 64 Evaluation 2 65 to 79 Evaluation 3 80 to 89 Evaluation 4 90 or more Evaluation 5 This relationship is recorded in the third selection circuit 15.

Note that this is an example, and a plurality of other relationships are recorded in the third selection circuit 15 depending on sex and the like.

According to the above relationship, when the person to be measured inputs the heart rate by the exercise test to the third selection circuit 15 with the condition value input switch 12 together with the sex, the evaluation value corresponding to the information input by the third selection circuit 15. Is determined, and a correlation line that approximates the correlation line unique to the person to be measured is selected.

Comparing Circuit 21 In the comparing circuit 21, the following processing is performed. In this processing, in each of the selection circuits 13 to 15, only one circuit is activated to specify one correlation line, and two or three circuits are activated to correlate each circuit. There are cases where a straight line is specified, and each case will be described separately.

First, the case where only one selection circuit is activated will be described.

A signal (specification signal) for specifying the correlation straight line selected by one of the selection circuits 13 to 15 is transmitted to the comparison circuit 21.

The comparison circuit 21 receives only the specific signal from one selection circuit, and if the specific signal from another selection circuit is not received, transmits a notification signal to that effect to the selection circuit. As a result, in the selection circuit, the correlation straight line is called from the corresponding logical storage circuits 16 to 20 and sent to the calorie calculation circuit 22.

Next, the case where the two or three selection circuits 13 to 15 are activated will be described.

When the correlation straight lines corresponding to the person to be measured are individually selected, the selection accuracy may not always be sufficient. For example, since the first selection circuit 13 is used, the measurement condition (physical condition, measurement environment, etc.) cannot be generalized when the measurement subject measures his / her resting heart rate without any knowledge or experience. The error may increase. Also, if the method of the motion test of the third selection circuit 15 is not accurately executed, the measurement error becomes large and the selection of the correlation line becomes inaccurate.

Therefore, in order to eliminate the incorrect selection of the correlation line and improve the selection accuracy, two or three of the selection circuits 13 to 15 are commonly used for the determination.

In this case, the person to be measured has his or her resting heart rate,
Since the number of inputs of personal information differs depending on the degree of knowledge as to whether or not the athletic ability or the like is known, only the selection circuit in which the personal information is input is used for comparison. Therefore, there are cases where two selection circuits are shared and cases where three selection circuits are shared.

When two circuits are shared, for example, when the resting heart rate in the first selection circuit 13 and the score in the question form of the second selection circuit 14 are shared, the user first
The above-mentioned numerical values required for the second selection circuits 13 and 14 are input. In each of the selection circuits 13 and 14, the correlation straight line is selected according to the input numerical value, and the comparison circuit 21 is notified.

Since the comparison circuit 21 receives the two specific signals, the notification signal is not transmitted to the selection circuits 13 and 14. As a result, the selection circuits 13 and 1
The correlation line is not independently selected in 4, and the comparison circuits 21 compare the correlation lines selected by the selection circuits 13 and 14, respectively.

When the correlation lines selected by the two circuits 13 and 14 coincide with each other, the evaluation is determined. When the two circuits 13 and 14 have different selections, the display 9 displays an instruction to redo the input. On the other hand, when the person to be measured re-enters the personal information and the judgment is different depending on the re-input, the slope of the correlation line that is intermediate between the correlation lines selected by the two circuits 13 and 14 is newly calculated. Create and determine this as a correlation line.

In the case of sharing three circuits, when at least two circuits select the same evaluation, the evaluation is determined as a correlation straight line. If all three are different, the display 9 is instructed to re-input. Then, the evaluations of the re-input personal information are compared, and when two or more circuits select the same evaluation, the evaluation is determined as a correlation straight line. Also, when the three selections differ due to re-input, the intermediate evaluation is determined as the correlation line.

As described above, the accuracy of measurement can be improved by sharing two or three circuits depending on the amount of knowledge and the degree of understanding of the numerical value related to calorie consumption such as oxygen intake, exercise, and resting heart rate of the subject. ..

Calorie calculating circuit 22 In the calorie calculating circuit 22, selection circuits 13 to 15 are provided.
Alternatively, the calorie consumption is calculated according to the following calculation formula from the correlation line selected by the comparison circuit 21.

Calorie consumption (per unit time) = maximum oxygen intake * E * body weight E: energy amount per liter of oxygen Substituting the theoretical formula into this equation, calorie consumption (per unit time) = (b + ax) * E *
Weight Based on this formula, calorie consumption is calculated from the measured heart rate x. Further, the calorie consumption per unit time is integrated and the total calorie consumption is displayed on the display unit 9.

As described above, the person to be measured inputs the resting heart rate, the score of the question form or the numerical value of the exercise test as the personal information from the condition value input switch 12 in advance, so that any one of the selection circuits 13 to 15 can be selected. When a single circuit or two or more circuits are activated, the comparison circuit 21 compares the results from any one of the circuits 13 to 15 and selects a specific logical storage circuit 16 to 20 (or takes an intermediate value). Since the calorie calculation circuit 22 calculates the calorie consumption from the measured heart rate based on the correlation line in the selected logical storage circuits 16 to 20, specialized knowledge and complicated and expensive measuring equipment are not required. , Calorie consumption can be calculated with a simple operation, and it will be easy to handle.

Also, the physical strength of each individual (maximum oxygen uptake capacity)
With less error, it is possible to calculate calorie consumption as an optimal approximation for various exercises.

In this embodiment, the case where the heartbeat display device 5 is attached to the arm has been described as an example, but it may be attached to the waist by a holder or attached to a training machine for use.

Further, in the present embodiment, the heartbeat detector 1 is wound around the body by the band 2, but other means may be used as long as the heartbeat rate can be detected. For example, the heart rate detection electrodes 3 may be provided in both hands, or an optical heart rate detector may be attached to the ear or fingertip.

Further, in the present embodiment, a plurality of correlation straight lines are stored in each of the logic storage circuits 16 to 20, but they may be stored in one logic storage circuit having a high storage capacity, high processing capacity and the like. Good.
