This application claims the benefit of patent application number 2022-115535 filed in Japan on July 20, 2022, and the contents of that application are incorporated herein by reference.

The present technology relates to a fatigue evaluation device, a fatigue evaluation system, a fatigue evaluation program, and a fatigue evaluation method for evaluating fatigue of a subject.

Conventional technology

In recent years, attention has been paid to the management of athletes' condition. Assessing an athlete's fatigue is an important indicator when estimating the athlete's condition. Here, fatigue includes subjective fatigue based on the subject's subjectivity and objective fatigue obtained by measuring biological information of the subject. By considering subjective fatigue and objective fatigue, it is possible to decide on training menus and rest that are appropriate for the athlete, thereby making it possible to appropriately manage the athlete's condition. Specifically, for example, instead of deciding whether or not to practice based solely on an athlete's subjective level of fatigue, we can measure objective levels of fatigue such as autonomic nervous balance and changes in body water content. It is desirable to decide by considering the value.

As a conventional technique, a fatigue level evaluation system has been proposed that plots objective fatigue level and subjective fatigue level on two-dimensional coordinates and presents advice to the person being measured depending on where the coordinates are located in four quadrants. (For example, Japanese Patent No. 6535865). According to this fatigue level evaluation system, it is possible to evaluate the level of fatigue, which is an important index for estimating an athlete's condition.

In this embodiment, the biometric device 10 is a body composition meter that measures body composition, and the fatigue evaluation device 20 is a smartphone that executes the fatigue evaluation program of the embodiment. The device is not limited to a meter, and may be any device as long as it can acquire biological information for calculating an objective degree of fatigue, which will be described later. Further, the fatigue evaluation device 20 is not limited to a smartphone, and may be any information processing device that can execute a fatigue evaluation program, and may be any other type of computer device such as a tablet, laptop, or desktop. Furthermore, the fatigue evaluation system 100 may be configured by the biometric device 10 and the fatigue evaluation device 20 being integrated.

The fatigue evaluation system 100 may include multiple types of biomeasuring devices 10 that each measure different biometric information. For example, the biometric device 10 that measures body composition, that is, a body composition meter, and the biometric device 10 that measures heart rate, that is, a heart rate monitor, may be included in the fatigue evaluation system 100 as separate devices. Furthermore, other devices such as a sphygmomanometer that measures the blood pressure of the subject, an activity meter that counts the number of steps of the subject, and an automatic biochemistry analyzer that analyzes blood components serve as the biometric device 10 in the fatigue evaluation system. It may be included in 100.

The biometric device 10 and the fatigue evaluation device 20 can communicate with each other by short-range wireless communication. The biomeasuring device 10 transmits the biometric information of the subject acquired through measurement to the fatigue evaluation device 20 via short-range wireless communication. Note that instead of this, the biometric device 10 and the fatigue evaluation device 20 may each connect to the cloud and share the biometric information of the person to be measured via the cloud.

As shown in FIG. 1, the body composition meter, which is a biometric device 10, has a generally flat shape, and has a front electrode 101 for the left foot, a rear electrode 102 for the left foot, and a front electrode 102 for the right foot on its upper surface.

In this embodiment, the left foot front electrode 101 and the right foot front electrode 103 are used as current-carrying electrodes, and the left foot rear electrode 102 and the right foot rear electrode 104 are used as measurement electrodes. As described above, the body composition meter as the biometric device 10 of this embodiment is a BI type body composition meter equipped with four electrodes.

Furthermore, the biometric information acquired by the biometric device 10 is also displayed on the display unit 105.

FIG. 2 is a block diagram showing the configuration of the fatigue evaluation system according to the embodiment. The biomeasuring device 10 includes a weight measuring device 11, a bioelectrical impedance measuring device 12, and a communication device 13.

The weight measuring device 11 includes a load cell configured by a strain-generating body made of a metal member that deforms according to a load, and a strain gauge attached to the strain-generating body. When a person to be measured stands on the biomeasuring device 10, the strain body of the load cell is bent by the weight of the person to be measured, and the strain gauge expands and contracts. The resistance value (output value) of the strain gauge changes according to its expansion and contraction. The weight measuring device 11 calculates the weight from the difference between the output value (zero point) of the load cell when no load is applied and the output value when the load is applied. Note that the configuration for measuring body weight using a load cell may be the same as that of a general digital scale.

The bioelectrical impedance measurement device 12 passes a weak alternating current through the left foot front electrode 101 and the right foot front electrode 103, which are current-carrying electrodes, to connect the left foot rear electrode 103 and the right foot rear electrode, which are measurement electrodes. At 104, the potential difference is measured. Thereby, the bioelectrical impedance measuring device 12 acquires bioelectrical impedance consisting of the reactance component X and the resistance component R. The bioelectrical impedance measurement device 12 measures bioelectrical impedance at a plurality of frequencies, such as 5 kHz and 50 kHz. Note that when the biomeasuring device 10 is an eight-electrode type, the bioelectrical impedance measuring device 12 can measure the bioelectrical impedance of each part of the body.

Although not shown in FIG. 2, the biometric device 10 as a body composition meter measures the height, age, and gender of the subject, the weight measured by the weight measuring device 11, and the bioelectrical impedance measuring device. By applying the bioelectrical impedance measured in step 12 to a predetermined regression formula and calculating, fat percentage, fat mass, fat-free mass, muscle mass, visceral fat mass, visceral fat level, visceral fat area, subcutaneous It functions as a body composition measurement device that obtains body composition information such as fat mass, basal metabolic rate, bone mass, body water percentage, BMI (Body Mass Index), intracellular fluid volume, and extracellular fluid volume. .

In this embodiment, the biomeasuring device 10 measures the body weight and bioelectrical impedance of the subject as biological information, and the fatigue evaluation device 20 acquires the body weight and bioelectrical impedance as desired information of the subject. The biometric device 10 is not limited to this, but the biometric information includes heart rate (pulse rate), heart rate fluctuation (pulse rate fluctuation), life log such as activity level and sleep status, blood pressure, blood components, saliva components, and physiological activity. It may be a device that measures the concentration of a substance (hormone), the concentration of an antioxidant, the concentration of a metabolite, or information about a virus in the body. Alternatively, the number of biometric devices 10 is not limited to one, and a plurality of types of biometric devices 10 that acquire each of the above-mentioned biological information may be able to communicate with the fatigue evaluation device 20.

The fatigue evaluation device 20 includes a communication device 21, a storage device 22, an input device 23, an arithmetic device (processor) 24, and a display device 25. The communication device 21 establishes short-range communication with the communication device 13 of the biomeasuring device 10, and then receives the body weight and bioelectrical impedance sent from the communication device 13. The storage device 22 stores the degree of fatigue calculated by the calculation device 24. The input device 23 receives input by operation from the person to be measured.

By executing the fatigue evaluation program of this embodiment, the computing device 24 obtains a biological information acquisition section 241, an answer acquisition section 242, an objective fatigue degree calculation section 243, a subjective fatigue degree calculation section 244, a difference degree calculation section 245, It functions as a comprehensive fatigue degree calculation section 246, a correction section 247, a fatigue evaluation section 248, and a change calculation section 249. The fatigue evaluation program is provided as an application program to the fatigue evaluation device 20, which is a smartphone, via communication or a non-transitory computer-readable storage medium, and is executed by the arithmetic device 24.

The display device 25 is a device including a plurality of pixels such as a liquid crystal panel. The display device 25 displays the results of calculations performed by the calculation device 24.

The biological information acquisition unit 241 acquires the weight and bioelectrical impedance of the subject received from the biometric device 10 using the communication device 21. As described above, the biomeasuring device 10 may be a device that measures biometric information other than body weight and bioelectrical impedance, and in that case, the biometric information acquisition unit 241 measures the biometric information measured by such a device. Get information. Alternatively, these biometric information may be input via the input device 23.

The response acquisition unit 242 calculates a fatigue symptom score (CFQ11) (Tanaka M et al., Psychol Rep_2010, 106, 2, 567-575), a presenteeism questionnaire or VAS, and a fatigue questionnaire.

These answers are obtained by the subject inputting them using the input device 23. The answer acquisition unit 242 causes the display device 25 to display the question and answer input form, and acquires the answer input by the subject into the input device 23 in relation to the answer input form displayed on the display device 25. Alternatively, the response acquisition unit 242 may acquire responses input by the person using another device through communication or the like.

"Questions regarding fatigue-related disabilities" refer to questions that confirm the subject's subjective evaluation of the presence or absence of a causal relationship between fatigue and some type of disability. "Questions regarding disability due to fatigue" may include, for example, questions about whether the person feels that fatigue interferes with work, housework, or school work, and questions about illnesses that are thought to be the cause of fatigue. The ``fatigue questionnaire'' is a questionnaire that asks whether you are aware of any symptoms of fatigue, such as whether you feel tired or whether you feel tired even after a full night's sleep. It can be. As the presenteeism questionnaire, for example, WHO's Health and Work Performance Questionnaire (HPQ) or Work Limitations Questionnaire (WLQ) may be used.

The objective fatigue level calculation unit 243 calculates the objective fatigue level based on the biological information acquired by the biological information acquisition unit 241. Specifically, the objective fatigue level calculation unit 243 calculates the objective fatigue level based on the reactance X and resistance R of the subject acquired by the body composition measuring device 12 of the biometric device 10.

FIG. 3 is a diagram showing a graph for determining the objective fatigue level according to the embodiment. In FIG. 3, the vertical axis is reactance X, and the horizontal axis is resistance R. In this graph, a reference line 31 is set that indicates a criterion for evaluating that there is no fatigue. The reference line 31 is set as a straight line of a linear function of X and R. The objective fatigue level calculation unit 243 calculates the distances of the obtained reactance X and resistance R from the reference line as a first fatigue level.

That is, the objective fatigue level calculation unit 243 sets the value of the axis D perpendicular to the reference line 31 as the first objective fatigue level. For example, when bioelectrical impedance A of reactance XA and resistance RA is obtained as shown in FIG. 3, the value DA on axis D of bioelectrical impedance A becomes the objective fatigue level. The objective fatigue level calculation unit 243 sets the range of the axis D so that the objective fatigue level ranges from 0 points (minimum fatigue level) to 100 points (maximum fatigue level). Here, the minimum fatigue level is a state where fatigue is accumulated, and the maximum fatigue level is a state where fatigue is not accumulated.

The graph shown in FIG. 3 is prepared for each predetermined weight range. Therefore, the objective fatigue level calculation unit 243 selects a corresponding graph from among the plurality of graphs prepared based on the body weight acquired by the biological information acquisition unit 241, and plots the bioelectrical impedance on the graph. Calculate the objective fatigue level.

As mentioned above, biological information for calculating objective fatigue level is not limited to bioelectrical impedance. For example, the biological information for calculating the objective fatigue level may be heart rate. In this case, the objective fatigue level calculation unit 243 calculates the objective fatigue level by comparing the resting heart rate at the time of measurement with the resting heart rate when there is no fatigue. Alternatively, the objective fatigue level calculation unit 243 may calculate the objective fatigue level by subtracting the heart rate after 60 seconds from the average heart rate during the last 30 seconds during exercise where the heart rate increases to 160 to 180.

Further, when the biological information acquisition unit 241 acquires both bioelectrical impedance and heart rate, the objective fatigue level calculation unit 243 calculates a first objective fatigue level based on the bioelectrical impedance and a first objective fatigue level based on the heart rate. The objective fatigue level may be calculated by weighting and adding the second objective fatigue level. The objective fatigue level calculation unit 243 weights the first objective fatigue level and the second objective fatigue level so that the objective fatigue level ranges from 0 points (minimum fatigue level) to 100 points (maximum fatigue level). to add.

Additionally, the biological information acquisition unit 241 may acquire the body weight measured by the weight measuring device 11 as the biological information. Intense exercise can cause dehydration through sweating, which can lead to weight loss. Additionally, neglecting proper hydration and nutrition afterwards can cause fatigue. Therefore, when the body weight has decreased rapidly compared to the previous day, the objective fatigue level calculation unit 243 determines that fatigue has accumulated and calculates the objective fatigue level.

The subjective fatigue level calculation unit 244 calculates the subjective fatigue level based on the answers acquired by the answer acquisition unit 242. A score is defined in advance for each answer, and the subjective fatigue level calculation unit 244 totals the scores of the plurality of answers of the subject to the questionnaire. If the response acquisition unit 242 has acquired responses to a plurality of questionnaires, the subjective fatigue level calculation unit 244 further adds up the total scores of each questionnaire. The subjective fatigue level calculation unit 244 calculates the subjective fatigue level so that the subjective fatigue level ranges from 0 points (minimum fatigue level) to 100 points (maximum fatigue level).

FIG. 4 is a diagram showing a graph for explaining calculation of the degree of difference according to the embodiment. The graph of FIG. 4 represents two-dimensional coordinates in which the horizontal axis is the objective fatigue level DO and the vertical axis is the subjective fatigue level DS. Points corresponding to the objective fatigue level calculated by the objective fatigue level calculation unit 243 and the subjective fatigue level calculated by the subjective fatigue level calculation unit 244 are plotted on the graph of FIG. 4, but in the graph of FIG. The two-dimensional coordinates are defined such that the further to the right, the lower the objective fatigue level DO, and the higher the position, the lower the subjective fatigue level DS.

In the graph of Figure 4, the first quadrant is an area where both objective and subjective fatigue levels are low, the second quadrant is an area where objective fatigue levels are high and subjective fatigue levels are low, and the third quadrant is an area where objective fatigue levels are low. and the subjective fatigue level are both high, and the fourth quadrant is the area where the objective fatigue level is low and the subjective fatigue level is high. Each axis ranges from 0 points (minimum fatigue level) to 100 points (maximum fatigue level).

In the graph of FIG. 4, a line segment DO=DS connecting the points where the objective fatigue level DO and the subjective fatigue level DS match is set as the reference line 41. The difference calculation unit 245 calculates the amount of correction of the objective fatigue level DO and the objective fatigue level DS necessary to make the objective fatigue level DO and subjective fatigue level DS match, that is, the standard from the plotted points in the graph of FIG. The length of the perpendicular line drawn to the line 41 is calculated as the degree of difference d. As is clear from the graph of FIG. 4, the degree of dissimilarity d is calculated as d=(√2/2)×|DO−DS|.

In addition, in the graph of FIG. 4, a line segment connecting the points where the objective fatigue level DO and subjective fatigue level DS match is set as an example of a standard determined based on the objective fatigue level DO and subjective fatigue level DS. There is. When the fatigue level (DO, DS) of the subject is on this line segment, it means that the objective fatigue level DO and subjective fatigue level DS of the subject are in agreement. However, the criterion determined based on the objective fatigue level DO and subjective fatigue level DS does not have to satisfy the condition that the objective fatigue level DO and subjective fatigue level DS match. The standard determined based on the objective fatigue level DO and subjective fatigue level DS is, for example, expressed by a straight line or curve passing through the intersection of the objective fatigue level DO and subjective fatigue level DS, which improves the performance of the person being measured. Alternatively, it may be represented by a straight line or a curved line passing through an intersection point where at least one of the objective fatigue level DO and the subjective fatigue level DS is increased or decreased. Further, the reference may be obtained by shifting the reference line 41 of the graph of FIG. 4 in the vertical axis direction or the horizontal axis direction, or may be obtained by changing the slope of the reference line 41 of the graph of FIG. 4. . Alternatively, the reference may be represented by a plurality of discontinuous lines, for example, by a line that is discontinuous on the vertical axis and/or the horizontal axis of the graph in FIG.

The deviation between the objective fatigue level DO and the subjective fatigue level DS is evaluated from the distance between the plotted points and the reference line 41 (difference d). If the plotted point is located above the reference line 41, it indicates that the objective fatigue level DO is higher than the subjective fatigue level DS. On the other hand, if the plotted point is located below the reference line 41, it indicates that the subjective fatigue level DS is higher than the objective fatigue level DO, and the person is not feeling well or the impedance or pulse rate is low. It is possible that the patient is experiencing fatigue in areas that cannot be determined. Depending on the magnitude of this difference d and whether the resulting plot position is above or below the reference line 41, it becomes possible to quantitatively evaluate the deviation between the subjective fatigue level DS and the objective fatigue level DO. .

FIG. 5 is a diagram showing a graph for explaining another example of calculating the degree of difference according to the embodiment. The index for evaluating the deviation (difference) between the objective fatigue level DO and the subjective fatigue level DS is not limited to the orthogonal distance d between the coordinates where the results are plotted and the reference line, but also the distance from the plotted point to the coordinates that intersect with the reference line 41. A straight line parallel to the axis indicating the objective fatigue level DO or subjective fatigue level DS may be used. That is, the difference calculation unit 245 may calculate, as the difference, the amount of correction dO of the objective fatigue level DO necessary to match the objective fatigue level DO and the subjective fatigue level DS. Alternatively, the difference calculation unit 245 may calculate the correction amount dS of the subjective fatigue level DS necessary to make the objective fatigue level DO and subjective fatigue level DS match as the difference level.

The total fatigue level calculation unit 246 calculates the total fatigue level DT based on the objective fatigue level DO, subjective fatigue level DS, and difference degree d. Specifically, the total fatigue level calculation unit 246 calculates a value obtained by subtracting the difference degree d from the higher score of the objective fatigue level DO and subjective fatigue level DS as the total fatigue level DT. For example, if the objective fatigue level DO is 80 points and the subjective fatigue level DS is 60 points, d=(√2/2)×|DO-DS|=(√2/2)×|80-60|= 10√2, and the total fatigue level DT is calculated as 80-10√2≒66 points.

With this calculation method, it is possible to present a score that takes into account not only the respective scores of the objective fatigue level DO and subjective fatigue level DS, but also the degree of difference d between the objective fatigue level DO and subjective fatigue level DS. Another calculation method is to subtract the difference d from the average score of the objective fatigue level DO and subjective fatigue level DS, but this method calculates a low value, so the objective fatigue level DO It is desirable to set the total fatigue level DT as a value obtained by subtracting the difference degree d from the highest score of the subjective fatigue level DS.

By calculating the total fatigue level DT in this way, the total fatigue level calculation unit 246 can quantitatively evaluate the total fatigue level DT. Thereby, it is possible to grasp the fatigue level that combines the objective fatigue level DO and the subjective fatigue level DS. Moreover, this also makes it possible to evaluate the past changes in the overall fatigue level.

The fatigue evaluation unit 248 evaluates the subject's fatigue based on the objective fatigue level, subjective fatigue level, total fatigue level, and the degree of difference between the objective fatigue level and the subjective fatigue level. Ideally, the objective fatigue level and subjective fatigue level should match, but they may deviate from each other. Therefore, the fatigue evaluation unit 248 evaluates the subject's fatigue differently depending on whether the objective fatigue level is greater than the subjective fatigue level or the subjective fatigue level is greater than the objective fatigue level. Furthermore, the fatigue evaluation unit 248 evaluates the fatigue of the subject according to the magnitude of the degree of difference.

The fatigue evaluation unit 248 evaluates the fatigue of the subject as described above, and then determines advice according to the evaluation. The fatigue evaluation unit 248 determines advice by selecting advice according to the evaluation of fatigue from among a plurality of advices prepared in advance. This will be explained in detail below.

FIG. 6 is a table showing the relationship between fatigue degree evaluation and advice content according to the embodiment. The fatigue evaluation unit 248 determines the position of the objective fatigue level and subjective fatigue level (hereinafter simply referred to as "fatigue level") (DO, DS) with respect to the reference line 41 (whether they are above or below the reference line 41). , the distance between the fatigue level (DO, DS) and the reference line 41 (difference d), and the total fatigue level DT, and the advice to be presented to the subject is determined according to the table in FIG. 6. .

As mentioned above, if the fatigue level (DO, DS) is above the reference line 41, it indicates that the objective fatigue level DS is higher than the subjective fatigue level DO; If it is below, it indicates that the subjective fatigue level DS is higher than the objective fatigue level DO. If the objective fatigue level DO is relatively high, the person may feel less fatigued, but in reality, fatigue has accumulated, which may increase the amount of exercise and increase the risk of injury. Therefore, the fatigue evaluation unit 248 determines advice that informs that such a possibility may occur as the advice to be presented. On the other hand, if the subjective fatigue level DS is relatively high, the risk of injury due to carelessness such as lack of concentration may increase. Therefore, the fatigue evaluation unit 248 determines advice that refreshes the mood or improves attention as the advice to be presented.

The fatigue evaluation unit 248 uses the difference degree d to evaluate the difference between the objective fatigue degree DO and the subjective fatigue degree DS, and determines advice in response thereto. For example, if d<5, it can be evaluated that the actual physical fatigue almost matches the sensation, and if d>20, it can be evaluated that there is a considerable deviation.

Further, by using the comprehensive fatigue level DT, the fatigue evaluation unit 248 can evaluate the fatigue level taking into account the objective fatigue level DO and the subjective fatigue level DS. For example, if the total fatigue level DT is a value close to 100, the fatigue evaluation unit 248 can determine advice to the effect that there is almost no fatigue and good physical performance can be achieved, and even if the total fatigue level DT is a value close to 0, Advice such as encouraging rest can be determined.

Here, the setting of numerical values for determining the advice to be presented shown in FIG. 6 is merely an example, and the fatigue evaluation unit 248 may set numerical values different from the example of FIG. 6. Further, the content of the advice shown in FIG. 6 is merely an example, and the fatigue evaluation unit 248 may prepare advice different from the example shown in FIG. 6.

FIG. 7 is a graph showing changes in fatigue level in the embodiment. FIG. 8 is a table showing the relationship between changes in fatigue level and advice content according to the embodiment. The change calculation unit 249 calculates a change from the previously calculated objective fatigue level and subjective fatigue level to the subsequently calculated objective fatigue level and subjective fatigue level. The change calculation unit 249 generates a vector (hereinafter referred to as a "fatigue level change vector") whose starting point is the past fatigue level and whose end point is the current fatigue level.

The fatigue evaluation unit 248 determines the advice to be presented according to the direction and magnitude of the fatigue level change vector generated by the change calculation unit 249. Specifically, the fatigue level evaluation unit 249 indicates the degree of recovery of the body based on the magnitude of the horizontal axis component (objective fatigue level) of the fatigue level change vector, and the vertical axis component (subjective fatigue level) of the fatigue level change vector. ) is determined as the advice to be presented, which indicates the degree of refreshment.

Using the table shown in FIG. 8, the fatigue evaluation unit 248 selects adverbs expressing the degree according to the magnitude of the fatigue level change vector, and also determines whether the subjective fatigue level and objective fatigue level are increasing or decreasing, respectively. By selecting the contents of the advice accordingly, the advice to be finally presented is determined.

The fatigue evaluation unit 248 may further compare the past fatigue level change vector and the current fatigue level change vector. For example, when you exercise, the fatigue level change vector points in the direction of increasing fatigue level, but even though you are doing the same exercise, the magnitude of the fatigue level change vector is smaller than the previous fatigue level change vector. It can be smaller than a vector. At this time, especially when the change in the objective fatigue level becomes small, the fatigue evaluation unit 248 provides advice that the body is adapting to the exercise, advice that muscle mass is increasing, or advice that nutritional intake is insufficient. Advice that is effective for fatigue may be determined as the advice to be presented. Furthermore, when the change in the subjective fatigue level becomes small, the fatigue evaluation unit 248 may determine that the advice to present is that mental strengthening has occurred.

In addition, by taking a rest after exercise, the fatigue level change vector will point in the direction of decreasing fatigue level, but even if the fatigue level is the same, the magnitude of the fatigue level change vector will decrease. may be larger than the previous fatigue level change vector. At this time, especially when the change in the objective fatigue level becomes large, the fatigue evaluation unit 248 may determine that nutritional intake and rest are effective in preventing fatigue. Further, when the change in the subjective fatigue level becomes large, the fatigue evaluation unit 248 may determine that the advice to present is that mental strength has occurred.

In this way, the fatigue evaluation unit 248 compares the fatigue level change vector in the past with the current fatigue level change vector, and determines the advice based on the result as the advice to be presented, so that the subject can evaluate his/her own growth level. It becomes possible to understand.

If the absolute value of the fatigue level is biased, it is effective to perform relativization based on the individual's past data. Therefore, the correction unit 247 corrects the total fatigue level calculated by the total fatigue level calculation unit 246 based on the past total fatigue level of each subject.

FIG. 9A is a graph showing multiple past comprehensive fatigue levels of a certain subject. FIG. 9B is a graph showing multiple past comprehensive fatigue levels after correction. When the average value of the past data of the total fatigue level is 50 or more, the correction unit 247 fixes the total fatigue level plotted at the upper right corner, and when the average value of the overall fatigue level is less than 50, fixes the total fatigue level plotted at the lower left corner. Fix the overall fatigue level plotted in , and find a conversion formula that makes the average value of past data 50.

When the new total fatigue level is obtained, the correction unit 247 corrects the total fatigue level using the conversion formula obtained above. Thereby, when the overall fatigue level is calculated multiple times and if there is any bias, it is possible to correct it and obtain an unbiased overall fatigue level. As a result, for example, if the dispersion of fatigue level values is small for people, it is difficult to detect subtle changes in fatigue level due to the small dispersion, but by making corrections (intra-individual relativization), it is possible to It becomes easier to understand changes in

In the examples of FIGS. 9A and 9B, correction of the overall fatigue level has been described, but the correction unit 247 may correct the objective fatigue level calculated by the objective fatigue level calculation unit 243. In this case as well, the correction unit 247 fixes the objective fatigue level plotted on the far right when the average value of the past data of the objective fatigue level is 50 or more, and fixes the objective fatigue level plotted on the farthest right when the average value of the past data of the objective fatigue level is In this case, fix the objective fatigue level plotted on the far left and find a conversion formula that makes the average value of past data 50.

Alternatively, the correction unit 247 may correct the subjective fatigue level calculated by the subjective fatigue level calculation unit 244. In this case as well, the correction unit 247 fixes the objective fatigue level plotted at the top when the average value of the past data of the objective fatigue level is 50 or more, and fixes the objective fatigue level plotted at the top when the average value of the past data of the objective fatigue level is less than 50. In this case, fix the objective fatigue level plotted at the bottom and find a conversion formula that makes the average value of past data 50.

In these cases, the comprehensive fatigue degree calculation unit 246 calculates the difference degree d using the corrected objective fatigue degree DO and subjective fatigue degree DS, and calculates the difference degree d by using the thus calculated difference degree d and the corrected objective fatigue degree DO. The overall fatigue level DT may be calculated using the fatigue level DO and the subjective fatigue level DS. Alternatively, the fatigue evaluation unit 248 may determine advice to be presented to the subject using the corrected objective fatigue level and subjective fatigue level.

Furthermore, the correction unit 247 determines the threshold value of the dissimilarity degree d for determining advice in the fatigue evaluation unit 248 and the total fatigue level DT based on the past changes in the subject's objective fatigue level DO and subjective fatigue level DS. The threshold value (see FIG. 6) may be corrected. The fatigue evaluation unit 248 determines advice based on the difference degree d and the total fatigue degree DT using the corrected threshold value.

Additionally, the correction unit 247 may correct the reference line 41 based on past trends. For example, the correction unit 247 may shift the reference line downward in FIG. 4 for subjects who tend to report high levels of subjective fatigue.

Further, the correction unit 247 not only corrects at least one of the overall fatigue level, objective fatigue level, and subjective fatigue level based on the past trends of the subject, but also based on the correlation with the performance of the subject. , the overall fatigue level, the objective fatigue level, and the subjective fatigue level may be corrected. For example, if the performance of the subject is high, the correction unit 247 may correct at least one of the calculated subjective fatigue level DS and objective fatigue level DO of the subject to be lower. Furthermore, for example, the correction unit 247 may correct the calculated overall fatigue level to be low if the performance of the subject is high.

By correcting in this way, for example, it becomes easier to calculate the degree of fatigue that correlates with performance for each individual, and it becomes easier to aim for conditions that can improve performance. The performance of the person to be measured is a concept that includes the ability, achievements, achievements, results, etc. that the person to be measured can demonstrate through exercise, and the level of performance of the person to be measured is determined based on the results of competitions and selections. It may be determined based on the evaluation by the person being measured or the evaluation by people around the person (supervisor, coach, etc.). The fatigue evaluation system may further include means for determining whether the performance of the subject is high or low.

In addition, the correction unit 247 may shift the reference line 41 in FIG. 4 vertically or horizontally in accordance with the performance of a person whose performance is better if there is a slight deviation between the objective and subjective views. The slope may be corrected, or the reference line 41 may be formed as a curved line. For example, the correction unit 247 analyzes the past performance of the person to be measured and the past objective fatigue level DO and subjective fatigue level DS of the person to be measured, and determines the objective fatigue level that has a strong correlation with the performance. A straight line or a curved line passing through the combination of DO and subjective fatigue level DS may be re-formed as the reference line 41. Further, the correction unit 247 may reshape the reference line 41 every unit period.

The storage device 22 stores the objective fatigue level DO, subjective fatigue level DS, and total fatigue level DT calculated by the calculation device 24, as well as the fatigue level change vector generated by the change calculation unit 249.

The fatigue evaluation unit 248 further reads out the past objective fatigue level, subjective fatigue level, and total fatigue level stored in the storage device 22, and generates a graph showing their changes as presentation information.

FIG. 10 is a graph showing changes in past fatigue levels in the embodiment. In the graph of FIG. 10, the horizontal axis is the date, and the vertical axis is the objective fatigue level, subjective fatigue level, and total fatigue level. In addition, in the graph of FIG. 10, the vertical axis (fatigue level) indicates that the higher it goes, the less fatigue has accumulated, that is, the condition is better. This graph allows the person to be measured to intuitively understand changes in their respective fatigue levels. In addition, by setting match days, selection dates, etc. on the application's calendar on which you want to be in perfect condition, it will also be marked on the graph, encouraging you to condition yourself so that you are free of fatigue on that day. can.

FIG. 11 is a graph showing changes in past fatigue levels in the embodiment. The fatigue evaluation unit 248 generates presentation information that shows the transition of the objective fatigue level up to the present and also shows the transition of the objective fatigue level of past good examples as the target future objective fatigue level. To this end, the person to be measured first specifies on the application the past day on which he or she performed best and the future date on which he/she wishes to show best performance (for example, a match day or selection day).

The fatigue evaluation unit 248 calculates the number of days from the present to the specified future date, and reads the past objective fatigue level for the calculated number of days from the specified past date from the storage device 22. The fatigue evaluation unit 248 generates, as presentation information, a graph showing the read transition of the objective fatigue level in the past, together with the transition of the objective fatigue level up to the present, as the transition of the target objective fatigue level from the present to the future.

By checking such presented information, the person to be measured can plan conditioning such as training and rest so that the change in objective fatigue level will be similar to the past change from that day onwards. The fatigue evaluation unit 248 determines advice regarding conditioning based on the current objective fatigue level and the transition of the target objective fatigue level. For example, advice to increase the amount of exercise is determined when it is better to increase the fatigue level, and advice to encourage rest is determined when the user is entering the recovery period. Note that the fatigue evaluation unit 248 may correct the past favorable transition by converting it into the current actual value, instead of directly overlapping the past transition, and present the corrected value.

In the example of FIG. 11, the fatigue evaluation unit 248 generated the presentation information regarding the objective fatigue level, but instead of this, it may similarly generate the presentation information regarding the comprehensive fatigue level. In this case, the fatigue evaluation unit 248 reads out the past total fatigue level stored in the storage device 22, shows the transition of the total fatigue level up to the present, and uses the past total fatigue level as the target future total fatigue level. Generate presentation information showing the transition of the overall fatigue level for a good example.

Furthermore, since the subjective fatigue level can be easily manipulated by bias, it is desirable to use the objective fatigue level or the comprehensive fatigue level in order to determine advice regarding conditioning. By checking the changes in the overall fatigue level, you can confirm the rough target for the changes in the fatigue level. In addition, by checking the change in objective fatigue level, you can use it as a basis for making decisions, such as how much exercise load you should put on your practice menu that day, and how much sleep you should get.

The display device 25 displays the objective fatigue level, subjective fatigue level, and total fatigue level obtained by the calculation device 24, and also displays the advice determined by the fatigue evaluation unit 248 based on them. Furthermore, the display device 25 displays the fatigue level change vector generated by the change calculation unit 249 and the advice determined by the fatigue evaluation unit 248 according to the fatigue level change vector. Furthermore, the display device 25 displays information on the transition of each fatigue degree generated by the fatigue evaluation section 248, information on presentation of the transition of the target future fatigue degree, and advice related to the fatigue evaluation section 248. Display the determined advice.

FIG. 12 is a flowchart of a fatigue evaluation method using the fatigue evaluation system of the embodiment. The example in FIG. 12 shows an example in which advice is presented based on the overall fatigue level. First, the subject starts the fatigue evaluation program (step S121). The subject inputs answers to a plurality of questions for calculating the subjective fatigue level via the input device 23 (step S122). The answer acquisition unit 242 acquires the answer input into the input device 23. The subjective fatigue level calculation unit 244 calculates the subjective fatigue level based on the answers acquired by the answer acquisition unit 242 (step S123).

The person to be measured starts the biometric device 10 (step S124). The weight measuring device 11 of the biomeasuring device 10 measures the weight of the subject (step S125). The bioelectrical impedance measuring device 12 then measures the bioelectrical impedance of the subject (step S126). The objective fatigue level calculation unit 243 calculates the objective fatigue level based on the weight and bioelectrical impedance measured by the biometric device 10 and acquired by the biometric information acquisition unit 241 from the biometric device 10 (step S127).

The correction unit 247 corrects the subjective fatigue level by converting the subjective fatigue level calculated by the subjective fatigue level calculating unit 244 using a conversion formula based on a plurality of past subjective fatigue levels (step S128). The difference degree calculation unit 245 calculates the degree of difference between the objective fatigue degree calculated by the objective fatigue degree calculation unit 243 and the subjective fatigue degree calculated by the subjective fatigue degree calculation unit and corrected by the correction unit 247 (step S129). The overall fatigue level calculation unit 246 calculates the objective fatigue level calculated by the objective fatigue level calculation unit 243, the subjective fatigue level calculated by the subjective fatigue level calculation unit and corrected by the correction unit 247, and the difference level calculation unit 245. A comprehensive fatigue level is calculated using the calculated degree of difference (step S130).

The fatigue evaluation unit 248 determines advice to be presented based on the total fatigue level calculated by the total fatigue level calculation unit (step S131). The display device 25 presents the advice determined by the fatigue evaluation unit 248 to the subject by displaying it (step S132).

In the example of FIG. 12, answers for calculating the subjective fatigue level are first input (step S122), and then biological information is measured for calculating the objective fatigue level (steps S125, S126). However, the input of answers and the measurement of biological information may be performed at the same time, in parallel, or at different timings. Either the subjective fatigue level calculation (step S123) or the objective fatigue level calculation (step S127) may be performed first. However, as in the example of FIG. 12, by inputting the answer of the person to be measured (step S122) before calculating the objective fatigue level (step S127), the bias applied to the person to be measured can be removed. In other words, if the person being measured first knows the objective fatigue level and then inputs the answer for calculating the subjective fatigue level, the person being measured tends to enter a value close to the objective fatigue level for that day. Such biases will disappear.

As described above, according to the fatigue evaluation system 100 of the present embodiment, it is possible to evaluate the fatigue level and present advice by taking into account the degree of difference between the objective fatigue level and the subjective fatigue level.

Note that in the above embodiment, the fatigue evaluation system 100 has been described assuming the fatigue level management or conditioning of athletes, but the fatigue evaluation system 100 is also effective when applied to users other than athletes.
