By measuring the load by each of the load sensors 14, it is possible to measure the load applied to the measuring table 11 and the balance (position of the center of gravity in the measuring table 11).
However, the number and arrangement of the load sensors 14 may be any as long as they can measure the load and the balance applied to the measuring table 11. For example, the three load sensors 14 may be arranged at positions surrounding the electrodes 12 so that the load applied to the measuring table 11 is supported by the three load sensors.
Based on the load measured by each of the load sensors 14, the processing device 20 calculates the weight of the user and the position of the center of gravity on the measuring table 11.

The interface circuit 24 includes a signal line connection terminal, and exchanges data with the interface circuit 15 of the measuring device 10 via the signal line. In particular, the interface circuit 24 receives the bioimpedance measured by the bioimpedance measuring circuit 13 and the load measured by each of the load sensors 14 from the interface circuit 15.

The storage device 28 stores various data. In particular, the storage device 28 stores the history of each of the muscle strength index, the muscle power index, the muscle quality index, and the muscle mass index calculated by the CPU 29. These histories stored in the storage device 28 are for the CPU 29 to calculate the rate of change of the muscle strength index, the rate of change of the muscle power index, the rate of change of the muscle quality index, and the rate of change of the muscle mass index.

The CPU 29 performs various processes by reading a program from the storage device 28 and executing the program.

FIG. 3 is a schematic block diagram showing a functional configuration of the processing device 20. In the figure, the processing device 20 includes a display unit 210, an operation input unit 220, a communication unit 230, a measured value acquisition unit 240, a storage unit 280, and a control unit 290. The control unit 290 includes a load calculation unit 291, a body composition index calculation unit 292, a change information acquisition unit 293, an estimated energy requirement calculation unit 294, a type determination unit 295, and a countermeasure determination unit 296.
The display unit 210 is configured by using the display device 21 and displays various images.
The operation input unit 220 is configured by using the input device 22 and receives a user operation.
The communication unit 230 is configured by using the communication circuit 23, and communicates with other devices.
The measured value acquisition unit 240 is configured by using the interface circuit 24, and receives the bioimpedance measured by the bioimpedance measuring circuit 13 and the load measured by each of the load sensors 14 from the measuring device 10.
The storage unit 280 is configured by using the storage device 28 and stores various information.

The control unit 290 controls each unit of the processing device 20 to perform various processes. The control unit 290 is configured by the CPU 29 reading a program from the storage device 28 and executing the program.
The load calculation unit 291 subtracts the weight of the measuring table 11 from the total of the loads measured by the four load sensors 14 to calculate the load applied to the measuring table 11. That is, the difference between the total of the four load sensors when the user is on the measuring table and the total of the four load sensors when the user is not on the measuring table is shown as the weight of the user.
The body composition index calculation unit 292 obtains a user's body composition index (for example, body fat percentage) based on the bioimpedance received from the measuring device 10 by the interface circuit 24.
The change information acquisition unit 293 acquires the change rate of the muscle strength index, the change rate of the muscle power index, the change rate of the muscle quality index, and the change rate of the muscle mass index. As mentioned above, these values correspond to the example of change information.

The change information acquisition unit 293 acquires the biometric information of the user whose input device 22 has received the input operation and stores it in the storage unit 280. Then, the change information acquisition unit 293 has muscle strength based on the bioimpedance acquired by the measured value acquisition unit 240 and the load calculated by the load calculation unit 291 and, if necessary, based on the user's biometric information. Each of the index, the muscle power index, the muscle quality index, and the muscle mass index is calculated, and the calculated value is stored in the storage unit 280.
Further, the change information acquisition unit 293 reads the past value (for example, the previous value) of the muscle strength index from the storage unit 280, subtracts it from the calculated current value, and divides the subtraction result by the past value to 100. By multiplying by, the rate of change of the muscle strength index is calculated. Similarly, the change information acquisition unit 293 calculates the rate of change for each of the muscle power index, the muscle quality index, and the muscle mass index.
As the past value used by the change information acquisition unit 293 (past value of muscle strength index, past value of muscle power index, past value of muscle quality index, and past value of muscle strength index), for example, 3 months. Past values from various periods, such as before, 6 months ago, or 1 year ago, can be used.
The estimated energy requirement calculation unit 294 calculates the estimated energy requirement. The estimated energy requirement here is a habitual daily energy intake estimated to have the highest probability that the energy balance will be zero.

The type determination unit 295 determines which of the 13 types shown in FIGS. 9 and 10 described later corresponds to the type of change in the muscle state based on the change information acquired by the change information acquisition unit 293.
However, the type determined by the type determination unit 295 is not limited to that shown in FIGS. 9 and 10. For example, as will be described later with reference to FIG. 11, the type determination unit 295 may determine the type of change in muscle condition for the elderly. Alternatively, as will be described later with reference to FIGS. 12 and 13, the type determination unit 295 may determine the type of change in muscle state based on the evaluation according to the age of the user.
The countermeasure determination unit 296 determines a countermeasure against the change in the muscle state based on the type of the change in the muscle state determined by the type determination unit 295. Specifically, the countermeasure decision unit 296 determines the recommended exercise, the recommended diet, or both.

Next, the processing performed by the motor function determination system 1 will be described.
FIG. 4 is an explanatory diagram showing an example of a processing procedure performed by the motor function determination system 1.
In the process of the figure, the operation input unit 220 receives input of biometric information about the user, such as a questionnaire about the height, age, gender, and the amount of activity of the user (step S101). Then, the change information acquisition unit 293 acquires the biological information and stores it in the storage unit 280. If the storage unit 280 has already stored the biometric information, in step S101, the change information acquisition unit 293 reads the biometric information from the storage unit 280 instead of inputting the biometric information to the operation input unit 220. You may do it. As a result, the user does not need to perform the input operation of the biometric information, and the burden on the user can be reduced in this respect.

Next, the bioimpedance measurement circuit 13 measures the bioimpedance of the user, and the load calculation unit 291 calculates the load such as the weight of the user (step S102).
FIG. 5 is an explanatory diagram showing the movement of the user when measuring the bioimpedance and calculating the load.
As shown in (1) of the figure, the user sits on a chair placed near the measuring device 10 with his / her foot resting on the measuring table 11 of the measuring device 10. At that time, the user becomes a bare foot and puts the foot so that both the left foot and the right foot are in contact with both the energizing electrode 12a and the measuring electrode 12b.

Next, as shown in (2) of the figure, the user stands up from the state of sitting on the chair. At that time, the user keeps both the left foot and the right foot in contact with both the current-carrying electrode 12a and the measuring electrode 12b.
Further, as shown in (3) of the figure, the user stands on the measuring table 11 and waits until the body becomes stable without wobbling. At that time, the user keeps both the left foot and the right foot in contact with both the current-carrying electrode 12a and the measuring electrode 12b.

In this way, while the user performs the standing up operation, the load calculation unit 291 obtains the load applied to the measuring table 11 and the position of the center of gravity of the measuring table 11 based on the load measured by the load sensor 14. Further, the bioimpedance measuring circuit 13 has a bioimpedance (impedance Z, resistance component R of impedance Z, and reactance) based on the current between the left and right energizing electrodes 12a and the potential difference (voltage) between the left and right measuring electrodes 12b. Find the component X).

FIG. 6 is a graph showing an example of the load calculated by the load calculation unit 291. The horizontal axis of the figure shows the time, and the vertical axis shows the load. Further, F in the figure shows the maximum value of the load calculated by the load calculation unit 291 in a series of operations, w indicates the weight of the user, and 0 is the value when nothing is on the measuring table. Is shown.
In the section at time T11, as shown in (1) of FIG. 5, when the user tries to stand up from the state of sitting on the chair, the load is first transferred to the buttocks, and the chair supports the load, so that the load calculation unit 291 The load calculated by is reduced once. After that, the load applied to the chair at the buttocks decreases, and the load calculated by the load calculation unit 291 increases. The load calculated by the load calculation unit 291 becomes maximum near the time when the buttocks are separated from the chair.

In the section at time T12, as shown in FIG. 5 (2), the user is in the process of getting up from the chair, and after the load increases at time T11, the load calculated by the load calculation unit 291 decreases.
In the section at time T13, when the user stands up as shown in FIG. 5 (3), the load calculated by the load calculation unit 291 converges on the weight w of the user.

After step S102 in FIG. 4, the change information acquisition unit 293 obtains an index of muscle strength, an index of muscle power, an index of muscle quality, and an index of muscle mass based on the load and bioimpedance obtained in step S102. Acquire (step S103).
Here, changes in muscle strength, muscle power, muscle quality, and muscle mass will be described with reference to FIG. 7.

FIG. 7 is an explanatory diagram showing an example of the process of muscle weakening.
As the first stage when a muscle weakens, the muscle strength decreases due to a neurological factor. Specifically, commands such as contraction to the muscle are transmitted to the muscle and it becomes difficult to reduce the muscle strength.

As the next second stage, muscle atrophy occurs and muscle quality deteriorates. At that time, the muscles that atrophy differ between aging and inactivity. Inactivity here indicates lack of exercise or lack of exercise.
With aging, fast muscle fibers atrophy. In this case, the muscle contraction rate decreases. On the other hand, in the case of inactivity, slow muscle fibers atrophy. In this case, the muscle contraction rate does not decrease.

As the next third stage, muscle mass decreases.
Then, as the fourth stage, the maximum muscle strength (muscle power) decreases.
In this way, by looking at the changes in muscle strength, muscle power, muscle quality, and muscle mass, it is possible to know which stage is in the process of the change in muscle state shown in FIG. 7, and measures can be taken according to the stage. Therefore, as described above, the change information acquisition unit 293 calculates the rate of change of each of the muscle strength index, the muscle power index, the muscle quality index, and the muscle mass index.

(Acquisition of muscle strength index)
The change information acquisition unit 293 calculates the maximum value weight ratio F / w obtained by dividing the maximum value F of the load calculated by the load calculation unit 291 in step S102 of FIG. 4 by the user's body weight w as an index of muscle strength. However, the index of muscle strength acquired by the change information acquisition unit 293 is not limited to the maximum weight ratio F / w. For example, the change information acquisition unit 293 may calculate a value obtained by dividing the difference between the maximum value of the load and the minimum value of the load by the weight of the user as an index of muscle strength. Alternatively, the change information acquisition unit 293 may acquire the measured value of the grip strength using the grip strength meter as an index of the muscle strength, or acquire the measured value of the muscle strength by the handheld dynamometer as the index of the muscle strength. You may try to do it.

When the change information acquisition unit 293 uses the maximum value weight ratio F / w as an index of muscle strength, it is more accurate than the case where the difference between the maximum value of the load and the minimum value of the load is divided by the user's weight. Is considered to be high. This is because it may not be possible to accurately specify the timing at which the load is minimized.
When it is difficult to specify the maximum value of the load, the change information acquisition unit 293 first reduces the load to a predetermined small load threshold value (for example, 20% of the body weight) or less, and then first sets a predetermined large load threshold value (for example, the body weight). The maximum value of the load in the region increased to 105%) or more may be detected.

(Acquisition of muscle power index)
The change information acquisition unit 293 divides the maximum value RFD of the load change rate calculated by the load calculation unit 291 in step S102 of FIG. 4 by the user's weight w into the maximum change rate weight ratio RFD / w of the muscle power. Calculated as an index.
FIG. 8 is a graph showing an example of the rate of change of the load. The horizontal axis of the figure shows the time, and the vertical axis shows the rate of change of the load. If the rate of change is greater than 0, the load is increasing. On the other hand, when the rate of change is less than 0, the load is decreasing. The RFD in the figure shows the maximum value of the rate of change of the load.
However, the index of muscle power acquired by the change information acquisition unit 293 is not limited to the maximum rate of change body weight ratio RFD / w. For example, the change information acquisition unit 293 may acquire the measured value obtained by performing the constant velocity muscle strength measurement at different exercise speeds as an index of muscle power. Alternatively, the change information acquisition unit 293 may acquire the measured value of the result of the vertical jump or the measured value of the result of the standing long jump as an index of muscle power.

(Acquisition of muscle quality index)
The change information acquisition unit 293 calculates an index of muscle quality based on the bioimpedance measured by the bioimpedance measuring circuit 13 in step S102 of FIG. For example, the change information acquisition unit 293 calculates R / X by dividing the resistance component R in the bioimpedance by the reactance component X as an index of muscle quality.
However, the index of muscle quality acquired by the change information acquisition unit 293 is not limited to R / X. For example, the change information acquisition unit 293 may calculate the ratio of the impedance Zhigh at high frequency and the impedance Zlow at low frequency as an index of muscle quality. Further, for example, the change information acquisition unit 293 may calculate the value obtained by dividing the impedance Zlow at 5 kHz by the impedance Zhigh at 250 kHz as an index of muscle quality.

(Acquisition of muscle mass index)
The change information acquisition unit 293 calculates an index of muscle mass based on the bioimpedance measured by the bioimpedance measuring circuit 13 in step S102 of FIG. For example, the change information acquisition unit 293 calculates muscle mass using bioimpedance, weight, height, age, gender, etc., and divides the calculated muscle mass by the square of the user's height (Ht ² ). It should be noted that the muscle mass is divided by the square of the user's height as an index of the muscle mass in order to exclude or reduce the influence of the height because there is a correlation between the height and the muscle mass. The index of muscle mass obtained by dividing the muscle mass by the square of the user's height is expressed as "muscle mass / Ht ² ".
However, the index of muscle mass acquired by the change information acquisition unit 293 is not limited to muscle mass / Ht ² . For example, the change information acquisition unit 293 may calculate a value obtained by dividing the limb muscle mass by the square of the user's height (limb muscle mass / Ht ² ) as an index of the muscle mass. Alternatively, the change information acquisition unit 293 may calculate the value obtained by dividing the lower limb muscle mass by the square of the user's height (lower limb muscle mass / Ht ² ) as an index of the muscle mass, or calculate the lower limb muscle mass. A value divided by the user's body weight w (lower limb muscle mass / w) may be calculated as an index of muscle mass.

Further, after step S102 in FIG. 4, the estimated energy requirement calculation unit 294 calculates the estimated energy requirement (step S104).
Specifically, the estimated energy requirement calculation unit 294 calculates the value obtained by multiplying the basal metabolic rate by the coefficient of the physical activity level as the estimated energy requirement. For example, the estimated energy requirement calculation unit 294 stores the age, sex, and body weight in advance in association with each other, and reads out the basal metabolic rate associated with the user's age, sex, and body weight. In addition, the estimated energy requirement calculation unit 294 classifies the physical activity level into three stages of high, medium, and low from the answers to the questionnaire to the user, and reads out the coefficient stored in advance for each level according to the age. .. Then, the estimated energy requirement calculation unit 294 calculates the estimated energy requirement by multiplying the obtained basal metabolic rate by a coefficient.

After steps S103 and S104, the type determination unit 295 determines the type of the change in the muscle state of the user (step S105).
FIG. 9 is an explanatory diagram showing an example of a processing procedure for type determination of a change in the muscle state of the user performed by the type determination unit 295. The figure shows an example of a processing procedure for type determination of a change in muscle state for a general standard person.
In the figure, the type determination unit 295 determines whether or not the rate of change Δ% F / w of the index of muscle strength is smaller than 0, that is, whether or not the muscle strength is reduced (step S201). Note that F / w is a value obtained by dividing muscle strength F by body weight w, and corresponds to an example of an index of muscle strength. Further, "Δ%" indicates the rate of change. For example, Δ% F / w indicates the rate of change of F / w.

After step S105 in FIG. 4, the type determination unit 295 determines the degree of muscle aging (step S106).
FIG. 12 is an explanatory diagram showing an example of an age-based evaluation processing procedure for a user's muscle condition performed by the type determination unit 295. The type determination unit 295 performs the process of FIG. 12 in step S106 of FIG.
In FIG. 12, the type determination unit 295 determines whether or not the user's age is less than 50 years old (step S401).
When it is determined in step S401 that the age of the user is less than 50 years old (step S401: YES), the type determination unit 295 indicates that the type determined in step S105 of FIG. 4 is an agile motion reduction type (type A) or agility. It is determined whether or not it is an operation deterioration caution type (type B) (step S402).

When it is determined in step S402 that it is an agile motion decrease type or an agility motion decrease attention type (step S402: Yes), the type determination unit 295 determines the daily volatility of muscle strength (that is, the volatility of muscle strength in days). The divided value) indicates weakness below the reference value (eg, 0.0022% decrease), or the daily volatility of muscle power (ie, the volatility of muscle power divided by the number of days) is the reference. It is determined whether or not muscle weakness is indicated rather than the value (step S403).
The daily volatility is expressed by the equation (1).

Volatility per day = {(Measured value this time-Past value) / Past value x 100 (%)} / Number of days from the day when the past value was measured to the day when the measured value this time was measured ... (1)

When it is determined in step S403 that all the volatility is lower than the reference value (step S403: Yes), the type determination unit 295 evaluates the muscle condition with a warning that the degree of muscle aging is high. Determination (step S404). In this case, the determination result in step S402 indicates aging of the muscle, and the determination result in step S403 indicates a rapid change in the state of the muscle. Therefore, the type determination unit 295 determines that special attention should be paid to muscle aging.

On the other hand, when it is determined in step S403 that at least one of the volatility does not show a decrease from the reference value (step S403: No), the type determination unit 295 evaluates the muscle state with a higher degree of muscle aging. (Step S405). In this case, the determination result in step S402 indicates aging of the muscle, while the determination result in step S403 indicates that the change in the muscle state is not rapid. Therefore, the type determination unit 295 determines that attention should be paid to muscle aging.

On the other hand, when it is determined in step S402 that it is neither the agile motion decrease type nor the agility motion decrease caution type (step S402: No), the type determination unit 295 determines that the type determined in step S105 of FIG. 4 is motion sustainability. It is determined whether or not it is a reduction type (type D) or an operation sustainability reduction caution type (type E) (step S406).
When it is determined in step S406 that it is a motion sustainability decrease type or an motion sustainability decrease caution type (step S406: Yes), the type determination unit 295 determines that the daily volatility of muscle strength is lower than the reference value. In addition, it is determined whether or not the daily volatility of muscle power indicates a decrease in muscle power than the reference value (for example, 0.0022% decrease) (step S407).

If it is determined in step S407 that any of the volatility is lower than the reference value (step S407: Yes), the type determination unit 295 warns that the muscle condition is evaluated with a high degree of muscle disuse. (Step S408). In this case, the determination result in step S406 indicates the non-utilization of the muscle, and the determination result in step S407 indicates a sudden change in the state of the muscle. Therefore, the type determination unit 295 determines that special attention should be paid to the disuse of muscles.

On the other hand, when it is determined in step S407 that at least one of the volatility does not show a decrease from the reference value (step S407: No), the type determination unit 295 evaluates the muscle state and the degree of muscle disuse is determined. It is determined that the caution is high (step S409). In this case, the determination result in step S406 indicates that the muscle is not utilized, while the determination result in step S403 indicates that the change in the muscle state is not rapid. Therefore, the type determination unit 295 determines that it is necessary to pay attention to the disuse of muscles.

On the other hand, when it is determined in step S406 that it is neither the motion sustainability decrease type nor the motion sustainability decrease caution type (step S406: No), in the type determination unit 295, the type determined in step S105 of FIG. 4 is muscular. Whether it is an atrophy type or a fat infiltration type is determined (step S410).
When it is determined in step S410 that it is a muscular atrophy type or a fat infiltration type (step S410: Yes), the type determination unit 295 determines that the evaluation of the muscle state is attention to the deterioration of the muscle structure (step S411).

On the other hand, when it is determined in step S410 that it is neither a muscle atrophy type nor a fat infiltration type (step S410: No), the type determination unit 295 determines that there is no problem in evaluating the muscle state (step S412).
On the other hand, if it is determined in step S401 that the age of the user is 50 years or older (step S401: NO), the process proceeds to step S421 in FIG.

FIG. 13 is an explanatory diagram showing an example of an age-appropriate evaluation processing procedure for a user's muscle condition, which is performed by the type determination unit 295 when it is determined that the user's age is 50 years or older. In the figure, the type determination unit 295 determines whether or not the type determined in step S105 of FIG. 4 is an agile motion reduction type (type A) or an agility motion reduction attention type (type B) (step S421).

When it is determined in step S421 that the type is agile motion weakness type or agile motion decline caution type (step S421: Yes), the type determination unit 295 changes the daily volatility of muscle strength to the first reference value (for example, 0. It is determined whether or not the muscle weakness is more than 0022% reduction) and the daily volatility of the muscle power is more than the first reference value (step S422).

When it is determined in step S422 that any volatility is lower than the first reference value (step S422: Yes), the type determination unit 295 determines that the daily volatility of muscle strength is the second reference value (step S422: Yes). For example, it is determined whether or not the muscle weakness is more than 0.0036%) and the daily volatility of the muscle power is more than the second reference value (step S423).
The administrator may be able to set and change either or both of the first reference value and the second reference value. Other reference values may also be set and changed by the administrator.

When it is determined in step S423 that any volatility is lower than the second reference value (step S423: Yes), the type determination unit 295 turns on the evaluation of the muscle state with a high degree of muscle aging. It is determined as a warning with caution (step S424). In this case, the determination result in step S421 indicates aging of the muscle, and the determination result in steps S422 and S423 indicate a rapid change in the state of the muscle. Therefore, the type determination unit 295 determines that special attention should be paid to muscle aging.

On the other hand, when it is determined in step S423 that at least one of the volatility does not show a decrease from the second reference value (step S423: No), the type determination unit 295 evaluates the muscle state and the degree of muscle aging. Is determined to be high caution (step S425). In this case, the determination result in step S421 indicates aging of the muscle, and the determination result in step S422 indicates a rapid change in the state of the muscle. On the other hand, the determination result in step S423 shows that the change in the muscle state is not abrupt as compared with the case of step S424. Therefore, the type determination unit 295 determines that attention should be paid to muscle aging.

On the other hand, when it is determined in step S422 that at least one of the volatility does not show a decrease from the first reference value (step S422: No), the type determination unit 295 evaluates the muscle state according to the age. It is determined that the muscles are reduced and the status quo will be maintained (step S426).

On the other hand, when it is determined in step S421 that it is neither the agile motion decrease type nor the agility motion decrease caution type (step S421: No), the type determination unit 295 determines that the type determined in step S105 of FIG. 4 is motion sustainability. It is determined whether it is a reduction type (type D) or an operation sustainability reduction caution type (type E) (step S427).
When it is determined in step S427 that it is a motion sustainability decrease type or an motion sustainability decrease attention type (step S427: Yes), the type determination unit 295 determines that the daily volatility of muscle strength is lower than the reference value. In addition, it is determined whether or not the daily volatility of muscle power indicates a decrease in muscle power than the reference value (for example, 0.0022% decrease) (step S428).

When it is determined in step S428 that any volatility is lower than the reference value (step S428: Yes), the type determination unit 295 evaluates the muscle condition and promotes the activity with a high degree of muscle disuse. It is determined as a warning that it is necessary to do so (step S429). In this case, the determination result in step S427 indicates the non-utilization of the muscle, and the determination result in step S428 indicates a sudden change in the state of the muscle. Therefore, the type determination unit 295 determines that special attention should be paid to the disuse of muscles.

On the other hand, when it is determined in step S428 that at least one of the volatility does not show a decrease from the reference value (step S428: No), the type determination unit 295 evaluates the muscle state and the degree of muscle disuse is determined. It is determined that the caution is high (step S430). In this case, the determination result in step S27 indicates that the muscle is not utilized, while the determination result in step S428 indicates that the change in the muscle state is not rapid. Therefore, the type determination unit 295 determines that it is necessary to pay attention to the disuse of muscles.

On the other hand, when it is determined in step S427 that it is neither the motion sustainability decrease type nor the motion sustainability decrease caution type (step S427: No), the type determination unit 295 indicates that the type determined in step S105 of FIG. 4 is a muscle. Whether it is an atrophy type or a fat infiltration type is determined (step S431).
When it is determined in step S431 that it is a muscular atrophy type or a fat infiltration type (step S431: Yes), the type determination unit 295 determines that the evaluation of the muscle state is attention to the deterioration of the muscle structure (step S432).

On the other hand, when it is determined in step S431 that it is neither a muscle atrophy type nor a fat infiltration type (step S431: No), the type determination unit 295 determines that there is no problem in evaluating the muscle state (step S433).
In this way, the type determination unit 295 evaluates the muscle state according to whether the user is under 50 years old or over 50 years old.

Further, after step S105 in FIG. 4, the countermeasure determination unit 296 makes an exercise action proposal (step S107). For example, the countermeasure determination unit 296 stores the 13 types of step S105 in advance in association with exercises such as walking. Then, the countermeasure determination unit 296 reads out the motion corresponding to the type determined by the type determination unit 295 in step S105 and presents it to the user. The exercise is presented to the user, for example, by displaying the exercise unit 210.

Further, after step S105 in FIG. 4, the countermeasure determination unit 296 makes a meal action proposal (step S108). For example, the countermeasure determination unit 296 stores the 13 types of step S105 in advance in association with the ingredients and the recipe plan. Then, the countermeasure determination unit 296 reads out the ingredients and the recipe plan corresponding to the type determined by the type determination unit 295 in step S105, and presents them to the user. This nutritional action proposal will be described with reference to FIGS. 14 to 17.

FIG. 14 is an explanatory diagram showing the relationship between muscle condition and the category of required nutrition. Each line in the figure shows the muscle condition, the criteria for determining the muscle condition, the cause and phenomenon of the muscle condition, and the category of nutrition required in the case of the muscle condition in association with each other.
For example, in the case of muscle weakness, the determination criterion is "Δ% F / w <0" as shown in step S201 of FIG. In addition, as causes and phenomena of muscle weakness, "decrease in information transmission amount", "nerve deterioration", "deterioration of muscle fiber composition ratio" and "many cells" are shown. It has also been shown that in the case of muscle weakness, brain nutrition is required.

FIG. 15 is an explanatory diagram showing the relationship between the 13 types of step S105 in FIG. 4 and the nutrition category shown in FIG. The rows in the figure correspond to 13 types from type A to type M, and the columns are (1) brain nutrition, (2) muscle contraction (nutrition required for muscle contraction), and (3) muscle. It corresponds to four nutrients: cells (nutrition required to prepare muscle cells) and (4) muscle glycogen.
The necessity of nutrition is indicated by the presence or absence of a pattern. For example, in the case of type B (awareness type for agility reduction), it is shown with a pattern that each of the above (1), (2), and (3) nutrition is required. On the other hand, it is shown without a pattern that nutrition (4) is not necessary as a countermeasure against type B.

FIG. 16 is an explanatory diagram showing the relationship between the nutrition categories shown in FIGS. 14 and 15 and specific nutrients. Each line in the figure shows the nutrition categories and specific nutrients in association with each other.
For example, with respect to brain nutrition, tryptophan (serotonin), phenylalanine, tyrosine (dopamine), GABA (γ-aminobutyric acid) and leucine have been shown as main nutrients. In addition, vitamin B6, vitamin B2 and magnesium have been shown as metabolic nutrients that promote the intake of tryptophan (serotonin).

FIG. 17 is an explanatory diagram showing the relationship between nutrients and foodstuffs. Each line in the figure shows the nutrients and the foodstuffs containing the nutrients in association with each other. For example, bananas, soymilk, milk, yogurt and processed cheese have been shown as ingredients containing tryptophan.
As shown in FIGS. 14 to 17, the type of change in muscle state can be associated with the foodstuff effective for the type.

Therefore, the countermeasure determination unit 296 stores in advance the 13 types of muscle states (types A to M), the ingredients effective for each type, and the recipes using the ingredients. Then, the countermeasure determination unit 296 reads out the ingredients and recipes associated with the type selected by the type determination unit 295 in step S105 of FIG. 4, and presents them to the user.

Alternatively, the countermeasure determination unit 296 stores in advance 13 types of muscle states and ingredients effective for each type. Then, the countermeasure determination unit 296 reads out the foodstuff associated with the type selected by the type determination unit 295 in step S105 of FIG. 4 and presents it to the user, and further searches for a recipe containing the foodstuff and presents it to the user. You may do so. Here, the countermeasure determination unit 296 searches for a recipe on the Internet, for example. Alternatively, the countermeasure determination unit 296 may search for recipes other than the Internet, such as searching for recipes in a dedicated database.

FIG. 18 is an explanatory diagram showing a first example of a display screen of a change in muscle state and a countermeasure displayed by the display unit 210. The figure shows an example of a display screen in the case of an agile motion reduction type (type A).
In the type display, in addition to the type name "Agile movement reduction type", changes in muscle strength, muscle power, muscle quality and muscle mass are indicated by arrows. Thick downward arrows indicate a large rate of decline, and thin downward arrows indicate a small rate of decline.
In addition, exercise proposals have shown effective training for agile motion-reducing types. In the nutritional proposal, ingredients and recipes that are effective for the agile hypoactivity type are shown for breakfast, lunch and supper.

FIG. 19 is an explanatory diagram showing a second example of the display screen of the type of change in the muscle state and the countermeasure displayed by the display unit 210. The figure shows an example of a display screen in the case of the operation sustainability reduction type (type D).
In the type display, in addition to the type name "movement persistence type", changes in muscle strength, muscle power, muscle quality and muscle mass are indicated by arrows. As in the case of FIG. 18, the thick downward arrow indicates a large reduction rate, and the thin downward arrow indicates a small reduction rate. On the other hand, the horizontal arrow indicates that the muscle mass has not decreased, that is, the muscle mass is maintained.
Also, as in the case of FIG. 18, the exercise proposal shows effective training for the agile motion-reducing type. In the nutritional proposal, ingredients and recipes that are effective for the agile hypoactivity type are shown for breakfast, lunch and supper.

The countermeasure determination unit 296 may also determine the timing of exercise and nutrition intake. For example, it is effective to take glycogen in the morning or after exercise. Therefore, the countermeasure decision unit 296 decides to take glycogen at breakfast or after exercise. Then, the display unit 210 displays exercise suggestions and recipes according to conditions such as ingesting glycogen at breakfast or after walking.

As described above, the change information acquisition unit 293 acquires change information indicating changes in a plurality of muscle indexes. Then, the type determination unit 295 determines the type of change in the muscle state based on the change information.
In this way, the type determination unit 295 determines the type based on the change in the muscle state, so that the type can be determined according to the problem that is occurring, and the type according to the cause such as aging or immobility. Judgment can be made. This makes it possible to present effective countermeasures for muscle conditions.

Further, the countermeasure determination unit 296 determines a countermeasure against the change in the muscle state based on the type of the change in the muscle state determined by the type determination unit 295.
