  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same components are denoted by the same reference numerals, and description thereof will not be repeated.

  In the following description, each component of the measuring apparatus 10 is not a configuration of a hardware unit but a block of a functional unit. For example, the measurement unit 120 includes a sensor and an arithmetic processing device. The processing unit included in the selection unit 140 and the measurement unit 120 includes, for example, a CPU or microcomputer of any computer, a memory, a program loaded in the memory, a storage medium such as a hard disk storing the program, and a network connection. It is realized by an arbitrary combination of hardware and software with a focus on the interface for software. There are various modifications of the method and apparatus for realizing the method.

  FIG. 1 is a block diagram illustrating a functional configuration of the measuring device 10 according to the embodiment. The measurement device 10 according to the embodiment includes a measurement unit 120 and a selection unit 140. The measurement unit 120 measures at least one of a carbohydrate concentration and a lipid concentration in a body fluid (for example, blood) of the exerciser. The selection unit 140 selects one of the first exercise and the second exercise with respect to the measurement result of the measurement unit 120, and outputs the selection result. Here, the first exercise is, for example, an anaerobic exercise, and the second exercise is, for example, an aerobic exercise. The output information may be a specific example of anaerobic exercise or a specific example of aerobic exercise. The measuring device 10 is, for example, a portable device, but may be a stationary device. The details will be described below.

  As described above, the measurement unit 120 measures at least one, and preferably both, of the carbohydrate concentration and the lipid concentration in the body fluid of the exerciser. The measurement unit 120 measures the carbohydrate concentration and the lipid concentration non-invasively. The measurement unit 120 has, for example, a light emitting unit and a light receiving unit. The light receiving unit receives the light from the light emitting unit via the body of the exerciser. Then, the measuring unit 120 measures at least one of the carbohydrate concentration and the lipid concentration in the body fluid using the intensity of the light received by the light receiving unit. For example, saccharides absorb light having a wavelength of around 1.6 μm and light having a wavelength of around 0.8 μm. Lipids absorb light having a wavelength of around 1.2 μm and light having a wavelength of around 0.6 μm. Therefore, the measuring unit 120 can measure the carbohydrate concentration and the lipid concentration in the body fluid by measuring the amount of light absorbed in these wavelength ranges. The operation timing of the measurement unit 120 is controlled by the selection unit 140, for example. The detailed configuration of the measurement unit 120 will be described later.

  The selection unit 140 selects one of the first exercise and the second exercise based on the measurement result of the measurement unit 120, and outputs the selection result. In the example shown in this figure, the measuring device 10 has an output unit 160. The output unit 160 is, for example, a display or a speaker, and outputs the result of selection by the selection unit 140 as text, video, audio, or both. Thereby, the user of the measuring device 10 can easily determine what kind of exercise he or she should do now.

  FIG. 2 is a diagram illustrating a first example of the measurement unit 120. In the example shown in the figure, the measuring unit 120 has a light emitting unit 122, a light receiving unit 124, a spectrum analyzing unit 126, and a density calculating unit 129. The light emitting unit 122 emits light toward the body F of the exerciser. The spectral distribution of this light includes, for example, the range of 1 μm to 2 μm, or the range of 0.5 μm to 1 μm, and includes both wavelengths absorbed by lipids and wavelengths absorbed by carbohydrates. The light source of the light emitting unit 122 is, for example, an LED or an organic EL element. The light receiving unit 124 detects light transmitted through the body F or light reflected by the body F among the light emitted by the light emitting unit 122. The light receiving unit 124 has, for example, a wavelength tunable filter, and can detect the intensity of light in a wide band, that is, the spectral distribution of light. Then, the spectrum analysis unit 126 detects at least one of the magnitude of the absorption spectrum due to the saccharide and the magnitude of the absorption spectrum due to the lipid from the spectrum distribution detected by the light receiving unit 124. Then, the concentration calculator 129 calculates at least one of the lipid concentration and the carbohydrate concentration from the magnitude of the absorption spectrum.

  FIG. 3 is a diagram illustrating a second example of the measurement unit 120. In the example shown in the figure, the measuring unit 120 includes a light emitting unit 122, a first wavelength filter 127, a second wavelength filter 128, a first light receiving unit 132, a second light receiving unit 134, and a density calculating unit 129. . The configurations of the light emitting unit 122 and the density calculating unit 129 are the same as those in the example shown in FIG. The first wavelength filter 127 transmits light having a wavelength absorbed by the saccharide, and cuts light having other wavelengths. The second wavelength filter 128 transmits light having a wavelength absorbed by the lipid and cuts light having other wavelengths. The first light receiving unit 132 detects the intensity of the light transmitted through the first wavelength filter 127, and the second light receiving unit 134 detects the intensity of the light transmitted through the second wavelength filter 128. Then, the concentration calculation unit 129 calculates the carbohydrate concentration in the body fluid based on the detection value of the first light receiving unit 132, and calculates the lipid concentration in the body fluid based on the detection value of the second light reception unit 134.

  Note that the measurement unit 120 may not include the first wavelength filter 127 and the first light receiving unit 132. In this case, the measurement unit 120 calculates only the lipid concentration in the body fluid. Further, the measuring section 120 may not have the second wavelength filter 128 and the second light receiving section 134. In this case, the measurement unit 120 calculates only the carbohydrate concentration in the body fluid.

  Further, the first light receiving unit 132 and the second light receiving unit 134 may be arranged not between the body F and the first light receiving unit 132 and the second light receiving unit 134 but between the body F and the light emitting unit 122. Furthermore, the first light receiving unit 132 and the second light receiving unit 134 may be provided both between the body F and the first light receiving unit 132 and the second light receiving unit 134 and between the body F and the light emitting unit 122. .

  FIG. 4 is a diagram illustrating a third example of the measurement unit 120. The measurement unit 120 shown in the figure has a first light emitting unit 131, a second light emitting unit 133, a light receiving unit 124, and a density calculating unit 129. The first light emitting unit 131 emits light having a wavelength absorbed by the saccharide, and the second light emitting unit 133 emits light having a wavelength absorbed by the lipid. The first light emitting unit 131 and the second light emitting unit 133 may have a laser element as a light emitting element. Note that the selection unit 140 shifts the light emission timing of the first light emitting unit 131 and the second light emitting unit 133.

  Then, the concentration calculation unit 129 calculates the carbohydrate concentration in the body fluid using the detection value of the light receiving unit 124 at the timing when the first light emitting unit 131 is operating. The concentration calculation unit 129 calculates the lipid concentration in the body fluid using the detection value of the light receiving unit 124 at the timing when the second light emitting unit 133 is operating.

  Here, when the selection unit 140 causes the first light emitting unit 131 to emit light, it is preferable that the first light emitting unit 131 be turned on in a first cycle. Further, when making the second light-emitting unit 133 emit light, it is preferable that the selection unit 140 cause the second light-emitting unit 133 to emit light at a second cycle different from the first cycle. In this case, the detection value of the light receiving unit 124 when detecting a carbohydrate has a first period, and the detection value of the light receiving unit 124 when detecting a lipid has a second period. Become. Therefore, a frequency filter (for example, a digital filter) that transmits a signal of the first cycle and a frequency filter (for example, a digital filter) that transmits a signal of the second cycle are provided in the signal processing circuit of the selection unit 140. When the carbohydrate concentration and lipid concentration are calculated using the detected values after passing through the filter, measurement errors of the carbohydrate concentration and lipid concentration can be reduced.

  The information received by the light receiving unit 124 when only the first light emitting unit 131 emits light is proportional to the carbohydrate concentration. Next, the first light emitting unit 131 is turned off, and only the second light emitting unit 133 is turned off. The information received by the light receiving unit 124 when is emitting light contains information proportional to the lipid concentration. For this reason, it is also an effective usage to make the first light emitting unit 131 and the second light emitting unit 133 emit light alternately.

  FIG. 5 is a diagram illustrating a fourth example of the measurement unit 120. The measurement unit 120 shown in the figure has the same configuration as the measurement unit 120 shown in FIG. 4 except that it has a first wavelength filter 127 and a second wavelength filter 128. The first wavelength filter 127 is arranged between the first light emitting unit 131 and the light receiving unit 124, and the second wavelength filter 128 is arranged between the second light emitting unit 133 and the light receiving unit 124. By doing so, the accuracy of the detection value of the light receiving unit 124 is increased, and as a result, measurement errors of the carbohydrate concentration and the lipid concentration are reduced.

  FIG. 6 shows a first example of the selection logic in the selection unit 140. In the example shown in the figure, the selection unit 140 selects one of the anaerobic exercise and the aerobic exercise using only the carbohydrate concentration. Specifically, the selecting unit 140 selects anoxic exercise when the carbohydrate concentration is equal to or higher than the first reference value, and selects aerobic exercise when the carbohydrate concentration is lower than the first reference value. This is because anaerobic exercise is suitable for consuming carbohydrates.

  FIG. 7 illustrates a second example of the selection logic in the selection unit 140. In the example shown in the figure, the selection unit 140 selects one of the anaerobic exercise and the aerobic exercise using only the lipid concentration. Specifically, the selection unit 140 selects aerobic exercise when the lipid concentration is equal to or higher than the second reference value, and selects aerobic exercise when the lipid concentration is less than the second reference value. This is because aerobic exercise is suitable for consuming lipids.

  FIG. 8 shows a third example of the selection logic in the selection unit 140. In the example shown in the figure, the selection unit 140 selects one of the anaerobic exercise and the aerobic exercise using both the carbohydrate concentration and the lipid concentration.

  Specifically, when the carbohydrate concentration is less than the first reference value and the lipid concentration is less than the second reference value, the selection unit 140 outputs an instruction to stop exercising and eat. When the carbohydrate concentration is equal to or higher than the first reference value and the lipid concentration is lower than the second reference value, the selection unit 140 selects anoxic exercise. When the carbohydrate concentration is lower than the first reference value and the lipid concentration is equal to or higher than the second reference value, the selection unit 140 selects aerobic exercise.

  When the carbohydrate concentration is equal to or higher than the first reference value and the lipid concentration is equal to or higher than the second reference value, the selection unit 140 outputs the following. First, when the value obtained by normalizing the carbohydrate concentration by the first reference value (first specified value) is larger than the value obtained by normalizing the lipid concentration by the second reference value (second specified value), When the concentration is higher than the concentration, the selection unit 140 selects the anaerobic exercise. On the other hand, when the first standard value is equal to or less than the second standard value, that is, when the lipid concentration is higher than the carbohydrate concentration, the selection unit 140 selects the aerobic exercise.

  Each drawing in FIG. 9 is a diagram illustrating an example of a display performed by the output unit 160. FIG. 9A is an example of a screen that recommends aerobic exercise, and FIG. 9B is an example of a screen that recommends anaerobic exercise. FIG. 9C is an example of a screen that recommends a meal when both the carbohydrate concentration and the lipid concentration are low (particularly when the carbohydrate concentration is low).

  As described above, according to the present embodiment, the measurement unit 120 measures at least one of the carbohydrate concentration and the lipid concentration in the body fluid. Then, the selection unit 140 selects one of the first exercise and the second exercise based on the measurement result of the measurement unit 120, and outputs the selection result. Therefore, the user of the measuring device 10 can easily determine what kind of exercise he or she should do now.

(Example 1)
FIG. 10 is a plan view of the measuring device 10 according to the first embodiment. In this embodiment, the measuring device 10 is a mobile phone or a smartphone, and has a housing 150. On the surface of the housing 150, a display unit as an example of the output unit 160 is provided.

  In addition, a recess 154 is provided on a side surface of the housing 150. The concave portion 154 is fitted with the user's finger when the user of the measuring device 10 holds the measuring device 10. The finger is, for example, an index finger, but may be a thumb, a middle finger, a ring finger, or a little finger.

  The light emitting unit 122 and the light receiving unit 124 are arranged in a region corresponding to the inner surface of the concave portion 154 on the side surface of the housing 150. Note that a first light emitting unit 131 and a second light emitting unit 133 may be arranged instead of the light emitting unit 122, and a first light receiving unit 132 and a second light receiving unit 134 are arranged instead of the light receiving unit 124. Is also good. The arrangement of the light emitting unit 122 and the light receiving unit 124 is not limited to the example shown in FIG.

  In this embodiment, the user recognizes the exercise to be performed by using the measurement device 10 before starting the exercise. Thereby, the user can perform an appropriate exercise.

(Example 2)
FIG. 11 is a cross-sectional view illustrating the configuration of the measuring device 10 according to the second embodiment. In this embodiment, the measuring device 10 is a clock-type device. The light emitting unit 122 and the light receiving unit 124 are arranged on the inner surface of the measuring device 10. Further, a display unit and an audio output unit as the output unit 160 are provided on the outer surface of the measuring device 10. Note that the first light emitting unit 131 and the second light emitting unit 133 may be arranged instead of the light emitting unit 122, and the first light receiving unit 132 and the second light receiving unit 134 are arranged instead of the light receiving unit 124. Is also good.

  In the present embodiment, the user wears the measuring device 10 on his / her arm before starting exercise. Then, both before starting the exercise and during the exercise, the user recognizes the exercise to be performed by using the measuring device 10. For example, when the time has not passed after eating, the user should perform anoxic exercise because the carbohydrate concentration in the body fluid is high. On the other hand, if the anaerobic exercise is continued, the carbohydrate concentration in the body fluid decreases due to the anaerobic exercise, and it is more preferable to switch to the aerobic exercise. The user can recognize the switching timing by using the measuring device 10. For example, the selection unit 140 of the measurement device 10 continues to periodically determine whether aerobic exercise or anaerobic exercise is preferable according to the criteria shown in FIG. Then, when it is time to switch from anaerobic exercise to aerobic exercise, the selection unit 140 causes the output unit 160 to output that effect. This allows the user to switch from anaerobic exercise to aerobic exercise at an appropriate timing.

  In addition, the selection unit 140 of the measurement apparatus 10 outputs an output indicating that exercise is stopped and a meal is taken when the carbohydrate concentration is equal to or less than the first reference value and the lipid concentration is equal to or less than the second reference value. The output unit 160 can also perform the processing.

  FIG. 12 is a diagram illustrating a first example of a transition of a screen displayed by the measuring device 10. In the example shown in the figure, the user exercises while wearing the measuring device 10. The measurement result by the measurement unit 120 before exercise corresponds to FIG. 8B of the embodiment. For this reason, the measurement apparatus 10 first displays a screen recommending anoxic exercise, as shown in FIG. Then, as the user of the measuring device 10 performs anaerobic exercise, the carbohydrate concentration (blood sugar level) decreases, and instead, the lipid dissolves into the blood and the lipid concentration increases. Then, when the measurement result of the measurement unit 120 corresponds to FIG. 8C, the measurement device 10 switches to a screen recommending aerobic exercise as shown in FIG. 12B. Then, when a predetermined condition is satisfied (for example, when the exercise time reaches a predetermined time), the measuring device 10 switches to a screen recommending that the exercise be ended, as shown in FIG.

  FIG. 13 is a diagram illustrating a second example of the transition of the screen displayed by the measuring device 10. Also in the example shown in this figure, the user exercises while wearing the measuring device 10. The measurement result by the measurement unit 120 before exercise corresponds to FIG. 8C of the embodiment. Therefore, the measuring apparatus 10 first displays a screen recommending aerobic exercise, as shown in FIG. Then, as the user of the measurement device 10 performs aerobic exercise, the lipid concentration decreases. Then, the measurement apparatus 10 switches to a screen for prompting to continue the aerobic exercise, as shown in FIG. Then, when the aerobic exercise is continued for a certain period of time, a screen prompting to end the exercise is displayed as shown in FIG. However, when the user continues the exercise further and the measurement result of the measuring unit 120 becomes equivalent to FIG. 8A, the measuring device 10 ends the exercise as shown in FIG. Switch to a screen prompting you to eat.

  In addition, when it is difficult to eat a normal meal, such as during a marathon or triathlon, it is also effective to display a method for easily raising the blood sugar level, such as candy, yokan, and sports drinks. In this way, it is possible to prevent the player from falling due to a lack of blood sugar level during the competition. In that case, assuming that the individual cannot recognize the insufficient blood sugar level, the measuring device 10 worn on the arm is equipped with a lighting device or a device that emits a sound, and flashes or sounds to notify the person and the surrounding people of danger. You may do it.

  FIG. 14 is a diagram illustrating a third example of the transition of the screen displayed by the measuring device 10. In these figures, a picture and a character (for example, a pig, a bird, a rice ball, etc.) are displayed on the screen of the measuring device 10 along with the text. And the number of the characters is proportional to the carbohydrate concentration and the lipid concentration. As a result, the user can intuitively grasp his or her current carbohydrate concentration and lipid concentration, that is, the results of exercise. At this time, the measuring device 10 may output sound. For example, when a change occurs in the lipid concentration, a sound “boooooo” may be output, and when a change occurs in the sugar concentration, the word “sweet” may be output as a voice.

(Example 3)
FIG. 15 is a diagram illustrating a method of using the measuring device 10 according to the third embodiment, together with its use environment. In the present embodiment, the plurality of measurement devices 10 are connected to the same information processing device 20 via the communication network 30. The plurality of measurement devices 10 are used by different users. Then, the use result of the measuring device 10 (for example, the time spent exercising using the measuring device 10) is transmitted to the information processing device 20. In the example shown in this figure, the measuring device 10 also has a function of acquiring the weight of the user.

  The information processing device 20 generates statistical data using the transmitted data. The statistical data is transmitted to the measurement device 10 via the communication network 30.

  FIG. 16 shows an example of a screen displayed by the measuring device 10 in the present embodiment. As described above, the measurement device 10 receives the statistical data from the information processing device 20. The measurement device 10 displays the statistical data together with the measurement result of the user of the measurement device 10. In the example shown in this figure, the statistical data shows the correlation between the cumulative average exercise time per day and the weight loss. By viewing this display, the user of the measuring device 10 can easily grasp the position of himself / herself as compared with other people.

  In FIG. 16, the vertical axis may be the amount of decrease in the body fat percentage. In this case, the body fat percentage is input to the measuring device 10.

  In addition, when the weight loss or the body fat percentage reduction does not satisfy the standards, the measuring device 10 may display a countermeasure method for reducing these, for example, foods and habits for improving these. The information displayed here is transmitted to the measurement device 10 by the information processing device 20, for example. The information processing device 20 transmits, to the measuring device 10, foods and habits whose effects have been proven by other users, for example. This proof is performed, for example, based on the result of a questionnaire to the user.

  As described above, according to the present embodiment, the user recognizes the exercise to be performed by using the measuring device 10 before starting the exercise. Thereby, the user can perform an appropriate exercise. In addition, since the measurement device 10 is operating even during the exercise, the user can switch from the anaerobic exercise to the aerobic exercise at an appropriate timing or end the exercise.

  As described above, the embodiments and examples have been described with reference to the drawings. However, these are examples of the present invention, and various configurations other than those described above can be adopted.
