WO2002 / 043586 Publication JP 2004-329412 JP Japanese Patent Laid-Open No. 2004-180939

  All of the above conventional devices were devised in an era when the body composition measurement technology was still insufficient, and therefore, fat mass and muscle mass can be measured only for the entire body, and therefore based on it. The advice was only rough.

  The present invention has been made in view of these points. The first object of the present invention is to understand more detailed body composition information such as muscle mass for each part of the body, which can be measured by the new technology. It is easy to display and make it easy for the user to understand, and more detailed and specific advice is given based on such detailed information, and the user then trains (or conditions) with a clearer sense of purpose. ) To provide an apparatus and a computer program that provide a guideline for performing the above.

The physical training advice device according to the present invention made to solve the above problems,
a) ideal muscle mass calculating means for calculating ideal muscle mass corresponding to each actual muscle mass based on the actual muscle mass which is the muscle mass of each part of the subject's body;
b) Display control means for displaying the actual muscle mass and ideal muscle mass of each part on the same graph on the display screen;
It is characterized by providing.

  The physical training advice device may further include target muscle mass calculating means for calculating the target muscle mass, and the display control means may display the target muscle mass on the graph.

  Furthermore, a training menu calculation means for calculating various training menus to be performed by the subject based on the target muscle mass and the actual muscle mass of each part of the body is provided, and the display control means may display the calculated training menu. Good.

  The actual muscle mass of each part of the subject's body can be measured by the body composition measuring device or the like. With this device, it is possible to individually measure the muscle mass at nine locations of the trunk, left and right upper arms, left and right forearms, left and right thighs, and left and right lower legs. In this case, these muscle masses may be displayed in a graph with a pentagonal radar chart in which the trunk is the upper vertex and the left and right upper arms, left and right forearms, left and right thighs, and left and right lower legs are associated with the corresponding vertices.

  Further, based on the measured muscle mass at the nine locations, detailed muscle mass calculation means for calculating more detailed muscle mass of each part using the Aquis-type chain equation is provided, and the display control means calculates the calculated detailed muscle mass. A similar polygon radar chart may be displayed as a graph.

  According to the physical training advice device according to the present invention, the ideal value is calculated from the input muscle mass of each part of the subject's body, and these are displayed on the same graph on the display screen. -Doctors and the like can clearly grasp which part of the subject's muscles should be strengthened, and can easily plan future training. The physical training advice device according to the present invention provides training advice for general people and sportsmen, rehabilitation of people who have been hospitalized due to injury, etc., muscle weakness, setting exercise targets for people whose muscles are weakening due to aging, etc. It can also be used.

  A physical training advice device according to the present invention will be described with reference to the drawings. The physical training advice device according to the present invention requires the muscle mass of each part of the body as its basic data. For example, the method and apparatus described in Patent Document 1 can be used to measure the muscle mass of each part of the body.

The outline of the measurement of muscle mass of each part of the human body by the body composition measuring apparatus described in Patent Document 1 is as follows. In this device, as shown in FIG. 2, the left and right arms (excluding the tip of the hand) are divided into the upper arm and the forearm near the elbow, and the left and right legs (excluding the tip of the ankle) are each near the knee. Divide into thigh and lower leg. In this way, the limb is divided into a total of 8 segments, and the trunk including the chest and abdomen is added to it, and the entire body is divided into 9 segments (left upper arm, upper right arm, left forearm, right forearm, Left thigh, right thigh, left lower leg, right lower leg and trunk). Each of the nine segments is associated with an independent impedance Z _LFA , Z _LUA , Z _RFA , Z _RUA , Z _LFL , Z _LCL , Z _RFL , Z _RCL , Z _T , as shown in FIG. Assume a connected model. Then, current flows from two of the _four current supply points Pi _{1 to} Pi 4 of the subject lying in the supine posture, and the voltage is measured at two corresponding points of the eight voltage measurement points Pv _{1 to} Pv _8. Then, the impedance value of each part is calculated. Based on the impedance value of each part, the muscle mass of each part is calculated based on a predetermined configuration model.

  The physical training advice device according to the present invention performs calculation and display for various advices based on the muscle mass thus measured. Therefore, it is convenient for the user that the body training advice device according to the present invention is integrated with the body composition measuring device. However, of course, it is also possible to create a device separate from such a body composition measuring device or to create a device that can be operated on a general-purpose personal computer.

In the above body composition measuring device, thus using the measured nine segments of muscle mass _{MM LUA, MM RUA, MM LFA} , MM RFA, MM LFL, MM RFL, MM LCL, MM RCL, the value of MM _T Thus, the balance of each part of the body composition can be evaluated.

As a balance evaluation, first, the balance of the left and right muscle mass is evaluated. Here, the left and right muscle mass ratio of each part is expressed as a numerical value. For example, the left / right balance of the upper arm
[Upper arm left / right balance (%)] = [Left upper arm muscle mass] / [Upper right arm muscle mass] × 100
And The closer this value is to 100, the better the balance between the left and right muscles.

Next, the balance of the upper limbs is evaluated. For example, the balance between the left upper arm and upper limb is
[Left upper arm upper limb balance (%)] = [Left upper arm muscle mass] / ([Left upper arm muscle mass] + [Left forearm muscle mass]) × 100 × (Correction factor)
And A correction coefficient is provided so that the closer this value is to 100, the better the balance between the left and right muscles.

In addition, the balance of the lower limbs is evaluated. For example, the balance between the left thigh and the lower limb is
[Left thigh balance (%)] = [Left thigh muscle mass] / ([Left thigh muscle mass] + [Left thigh muscle mass]) x 100 x (Correction factor)
And

  In addition, assess the balance of the trunk. Here, the ratio is determined by the ratio of ideal trunk muscle mass and trunk muscle mass. The ideal trunk muscle mass can be determined from the total body muscle mass of the subject.

Hereinafter, the operation of the physical training advice device according to the present invention for performing various conditioning advices based on data such as muscle mass measured by the body composition measuring device will be described.
First, the ideal muscle mass is calculated at nine locations: left and right upper arms, left and right forearms, left and right thighs, left and right lower legs, and trunk. These values are determined from the total body muscle mass. For example, in the case of ideal upper arm muscle mass,
[Ideal upper arm muscle mass] = [total body muscle mass] / (constant KX _UA )
And calculate. The left and right ideal muscle mass is the same. Here, the constant KX _UA is a constant determined regardless of the subject. By performing such calculation for each part of the limb, a total of nine ideal muscle masses are obtained.

  Next, the target muscle mass is calculated. The ideal muscle mass is an amount calculated from the sex and height of the subject, and is the same value for a person who is the same sex and has the same height. However, the target muscle mass is 10% of the current muscle mass (total muscle mass in the body). For example, if you are a sportsman, you will set a higher value than the ideal value. Also, a low value will be set. Also, the value may be raised or lowered depending on the desire of the person.

  Using the measured muscle mass, ideal muscle mass, and target muscle mass values of each part of the subject's body calculated in this way, the muscle mass that is currently lacking can be known for each part of the body. Provide training menu to subjects. Details thereof will be described in the following examples.

  The configuration and operation of a body composition measurement / advice device according to an embodiment of the present invention will be described. FIG. 1 is an external view of a body composition measurement / advice device according to this embodiment. As described above, this apparatus has a function for body composition measurement and a function for providing advice to the subject based on the measurement result.

  As shown in FIG. 1, this apparatus mainly comprises a notebook personal computer (hereinafter referred to as “personal computer”) 1 for performing various controls and data processing, and a main body 2 for mainly measuring impedance. The electrode group necessary for the measurement is taken out from the back surface of the main body 2 via the cable 4. A commercial AC power supply cable is connected to the main body 2 via an AC-DC adapter 3. The electrode group includes an electrode for current supply (hereinafter referred to as “electrode for energization”) 10 and an electrode for voltage measurement (hereinafter referred to as “electrode for measurement”) 11. The main body 2 is connected via an inductive cable 4. Both the energizing electrode 10 and the measuring electrode 11 can be reliably and stably attached to the skin surface of the subject, and are planar sticky electrodes so as to reduce the impedance (contact resistance) of the electrode itself. It has become.

  In the impedance measurement by this body composition measurement / advice device, the voltages at a maximum of 16 voltage measurement points are measured as will be described later, but four energization electrodes 10 and four measurement electrodes are measured. 11 is adopted. That is, when measuring at 8 or 16 voltage measurement points as will be described later, the tester repositions the measurement electrode 11 on the body of the subject every time the measurement at 4 locations is completed. . This is because if the number of electrodes increases, the cost of the apparatus increases, the cables get tangled, the measurement preparation becomes complicated, and an attachment error to the subject tends to occur. Of course, if such a point does not become a problem, a configuration in which 8 to 16 measurement electrodes are prepared from the beginning may be employed.

  The hard disk drive (or built-in ROM) of the personal computer 1 is used to perform calculation processing for estimating various body composition information and various information related to health conditions as described above based on the measurement of impedance and the measured value. And a control program for executing these measurements are stored. More specifically, by measuring a large number of monitors with different body-specific information such as height, weight, age, sex, etc. by MRI in advance and calculating a reliable regression analysis constant based on the measurement results A highly accurate estimation formula is acquired in advance. Then, this estimation formula is stored in a hard disk (or a built-in ROM) as a part of the arithmetic program. Then, by executing the program in accordance with an instruction given from the outside via the operation unit 5, the impedance measurement as will be described later and the subsequent various calculation processes and display processes are realized. Note that the estimation formula for such calculation processing does not necessarily have to be stored in the form of a calculation formula, but is stored in the form of a table, for example, and impedance measurement values and body identification information are input to the table. By doing so, it can be transformed into various forms such as obtaining body composition information and health related information as an output result.

  The personal computer 1 is turned on and started up, and the body composition is measured by using software (application) for displaying training guidelines and an electrode group connected to the main body.

  FIG. 2 shows an impedance model of a human body when measurement is performed in the body composition measurement mode. As shown in this figure, consider a model in which the body of a subject is divided into a total of nine parts: left and right upper arms, left and right forearms, left and right thighs, left and right lower legs, and trunk. The subject inputs the body specific information and measures nine segments.

  The examiner attaches the energization electrode and the measurement electrode to the body of the subject with reference to FIG. 2 in which the body is divided into nine segments. After wearing the electrodes, the subject instructs to start measuring body composition. Measurement is automatically started in response to this operation. The energization electrode and the measurement electrode are appropriately switched so that the measurement site sequentially shifts to the left arm, right arm, left leg, right leg, and trunk. Then, a weak high-frequency current is passed between the two selected energization electrodes, and the potential generated by the current is sequentially measured by the two measurement electrodes.

  When the measurement is completed, the impedance value obtained by the measurement and the body specifying information are applied to a predetermined estimation formula or a conversion table corresponding to the calculation formula to calculate the limb muscle mass. As the calculation processing method at this time, an estimation formula using body composition information obtained by MRI as described above can be used, but the estimation method is not necessarily limited thereto.

  Various calculations are performed using these measured values or input values, and various advice screens (conditioning screens) are created and displayed based on the results. 11 to 13 show various calculation results for creating a conditioning screen. The program of the present invention does not show the contents of these calculations to the subject, and displays specific advice based on the results of these calculations in an easy-to-understand manner for the subject using numerical values and messages.

  An example of the screen displayed to the subject is shown in FIG. The conditioning screen A includes a subject data display unit A1, limb muscle mass evaluation display unit A2, limb muscle distribution balance evaluation display unit A3, upper and lower body balance evaluation display unit A4, limb muscle mass display unit A5, and limb muscle mass distribution balance radar. It consists of a chart A6 and an exercise item balance display section A7. Detailed screens of each part are shown in FIGS. Hereinafter, each screen will be described in detail.

First, the muscle mass values of the nine segments of the left upper arm, upper right arm, left forearm, right forearm, left thigh, right thigh, left lower leg, right lower leg and trunk ( MM _LUA , MM _RUA , MM _LFA , MM _RFA , MM _LFL , MM _RFL , MM _LCL , MM _RCL , MM _T ) are displayed on the left side of the limb muscle mass evaluation display section A2 (FIG. 5). When the same apparatus 10 is used, these values are displayed using values measured by body composition measurement. On the other hand, when another device is used, the input value is displayed.

  As shown in FIG. 4, the subject data display section A1 includes a subject's name and text of body specifying information such as gender, age, height, weight, muscle mass, body fat mass, body fat percentage, ideal muscle mass, etc. A box is displayed. On the initial screen, click “Read Body Composition Result” to reflect the body specific information read.

The general ideal muscle mass (TMM _I ) displayed on the subject data display unit A1 is obtained as follows.
TMM _I = (HT / KX ₁ ) + KX ₂
Here, HT is a subject's height (cm), and KX ₁ and KX ₂ are constants determined by sex. The ideal muscle mass of each part of the body is calculated based on this ideal whole body muscle mass TMM _I. That is, ideal forearm muscle mass MM _HFA , ideal upper arm muscle mass MM _HUA , ideal thigh muscle mass MM _HFL , ideal lower leg muscle mass MM _HCL , ideal trunk muscle mass MM _HT are
MM _HFA = TMM _I / KX _HFA
MM _HUA = TMM _I / KX _HUA
MM _HFL = TMM _I / KX _HFL
MM _HCL = TMM _I / KX _HCL
MM _HT = TMM _I / KX _HT
Is calculated. Here, KX _HFA , KX _HUA , KX _HFL , KX _HCL , and KX _HT are constants determined for each segment.

Next, upper limbs, lower limbs, and trunk balance are calculated. The upper limb balance is calculated by the following formula.
BL _LUA = MM _LUA / (MM _LUA + MM _LFA ) × KX _BUA × 100
BL _RUA = MM _RUA / (MM _RUA + MM _RFA ) × KX _BUA × 100
BL _LFA = MM _LFA / (MM _LUA + MM _LFA ) × KX _BFA × 100
BL _RFA = MM _RFA / (MM _RUA + MM _RFA ) × KX _BFA × 100
That is, for example, the upper limb balance BL _LUA of the left upper arm is a percentage of the ideal value of the muscle mass of the left upper arm with respect to the muscle mass of the entire left arm (= left upper arm muscle mass + left forearm muscle mass). The correction coefficient KX in the above formula is a value determined in advance according to height, weight, age, sex, and the like from a standard human body composition. The same applies to the upper limb balances BL _RUA , BL _LFA , BL _RFA of the upper right arm, the left forearm, and the right forearm.

The calculation method of the lower leg balance BL _LFL , BL _RFL , BL _LCL , BL _RCL is also the same for the left thigh, right thigh, left lower leg, and right lower leg.
BL _LFL = MM _LFL / (MM _LCL + MM _LFL ) × KX _BFL × 100
BL _RFL = MM _RFL / (MM _RCL + MM _RFL ) × KX _BFL × 100
BL _LCL = MM _LCL / (MM _LCL + MM _LFL ) × KX _BCL × 100
BL _RCL = MM _RCL / (MM _RCL + MM _RFL ) × KX _BCL × 100

Trunk balance BL _T is the ratio of the measured trunk muscle mass with respect to an ideal torso muscle mass MM _IT.
BL _T = MM _IT / MM _T × 100
The ideal trunk muscle mass MM _IT is calculated using the total body muscle mass (TMM) and the constant KX _T as described above.
MM _IT = TMM / KX _T
Can be obtained. Here, KX _T is a constant determined regardless of the subject. An example of these calculation results is shown in the lower part of FIG. As mentioned above, this table is not shown to the subject.

The subject is presented with the values of the left and right muscle balances BL _UA , BL _FA , BL _FL , BL _CL of the upper arm, forearm, thigh, and lower leg calculated by the following formula. These values are displayed on the left side of the limb muscle mass evaluation display section A2 (FIG. 5).
BL _UA = (MM _LUA / MM _RUA -1) x 100
BL _FA = (MM _LFA / MM _RFA -1) x 100
BL _FL = (MM _LFL / MM _RFL -1) x 100
BL _CL = (MM _LCL / MM _RCL -1) x 100

Next, a method for calculating the ideal muscle mass will be described. The ideal muscle mass of each segment is determined using the total muscle mass (TMM) of the subject calculated by the previous body composition measurement. The ideal muscle mass for each segment, that is, ideal upper arm muscle mass MM _IUA , ideal forearm muscle mass MM _IFA , ideal thigh muscle mass MM _IFL , ideal lower leg muscle mass MM _ICL , ideal trunk muscle mass MM _IT is calculated by the following formula: The
MM _IUA = TMM / KX _IUA
MM _IFA = TMM / KX _IFA
MM _IFL = TMM / KX _IFL
MM _ICL = TMM / KX _ICL
MM _IT = TMM / KX _IT
Here, KX _IUA , KX _IFA , KX _IFL , KX _ICL , KX _IT are constants determined for each segment.

Subsequently, the difference between the ideal muscle mass calculated above and the current muscle mass is calculated. For each segment, determining the ideal muscle mass and the measured muscle mass difference _{MD LUA, MD RUA, MD LFA} , MD RFA, MD LFL, MD RFL, MD LCL, MD RCL, the MD _T as follows.
MD _LUA = MM _IUA −MM _LUA
MD _RUA = MM _IUA −MM _RUA
MD _LFA = MM _IFA −MM _LFA
MD _RFA = MM _IFA −MM _RFA
MD _LFL = MM _IFL −MM _LFL
MD _RFL = MM _IFL −MM _RFL
MD _LCL = MM _ICL −MM _LCL
MD _RCL = MM _ICL −MM _RCL
MD _T = MM _IT −MM _T

Next, a method for calculating the target muscle mass will be described. The target muscle mass can be obtained as an increase of 10% of the actually measured muscle mass. That is, the target muscle mass for each segment, that is, target upper arm muscle mass MM _TUA , target forearm muscle mass MM _TFA , target thigh muscle mass MM _TFL , target lower leg muscle mass MM _TCL , target trunk muscle mass MM _TT ,
MM _TUA = MM _LUA × 1.1
MM _TFA = MM _LFA × 1.1
MM _TFL = MM _LFL × 1.1
MM _TCL = MM _LCL × 1.1
MM _TT = MM _LT × 1.1
Is calculated.

Subsequently, the difference between the target muscle mass calculated above and the actually measured muscle mass is calculated. For each segment, the difference between the target muscle mass and the actually measured muscle mass TD _LUA , TD _RUA , TD _LFA , TD _RFA , TD _LFL , TD _RFL , TD _LCL , TD _RCL , TD _T is obtained by the following equation.
TD _LUA = MM _TUA -MM _LUA
TD _RUA = MM _TUA -MM _RUA
TD _LFA = MM _TFA -MM _LFA
TD _RFA = MM _TFA -MM _RFA
TD _LFL = MM _TFL -MM _LFL
TD _RFL = MM _TFL -MM _RFL
TD _LCL = MM _TCL -MM _LCL
TD _RCL = MM _TCL -MM _RCL
TD _T = MM _TT −MM _T

  FIG. 11 shows the ideal muscle mass, the target muscle mass, the difference between the actually measured muscle mass and the ideal muscle mass, and the difference between the actually measured muscle mass and the target muscle mass calculated as described above. As noted above, these values are not shown to the subject.

Furthermore, the ratio between the ideal muscle mass and the actually measured muscle mass is calculated. The ideal muscle mass ratio and the measured muscle mass ratio for each segment are shown as the left upper arm ideal muscle mass ratio IR _LUA , the upper right arm ideal muscle mass ratio IR _RUA , the left forearm ideal muscle mass ratio IR _LFA , and the right forearm ideal muscle mass ratio IR, respectively. _RFA, left thigh ideal muscle mass ratio IR _LFL, right thigh ideal muscle mass ratio IR _RFL, left lower leg ideal muscle mass ratio IR _LCL, right lower leg ideal muscle mass ratio IR _RCL, and the trunk ideal muscle mass ratio IR _T,
IR _LUA = MM _LUA / MM _IUA × 100
IR _RUA = MM _RUA / MM _IUA × 100
IR _LFA = MM _LFA / MM _IFA × 100
IR _RFA = MM _RFA / MM _IFA × 100
IR _LFL = MM _LFL / MM _IFL × 100
IR _RFL = MM _RFL / MM _IFL × 100
IR _LCL = MM _LCL / MM _ICL × 100
IR _RCL = MM _RCL / MM _ICL × 100
IR _T = MM _T / MM _IT × 100
It becomes.

Using the data thus obtained, the muscle balance of the subject and the distortion of the ideal muscle balance are displayed as points. If this point is large, it indicates that the difference from the ideal muscle balance is large. Thus, the subject can recognize the balance of the body composition intuitively by converting it into a point and displaying it to the subject. Brachial strain point, forearm strain point, thigh strain point, lower leg strain point, respectively muscle mass strain _{point, PD UA, PD FA, PD} FL, PD CL, when the PD _T, they PD _UA = | (BL _LUA + BL _RUA -200) |
PD _FA = | (BL _LFA + BL _RFA -200) |
PD _FL = | (BL _LFL + BL _RFL -200) |
PD _CL = | (BL _LCL + BL _RCL -200) |
PD _T = | TMM-TMM _I | × 100
Is calculated.

Subsequently, the distortion of the left and right muscle mass is displayed as a point. Brachial left-right balance strain point, forearm left-right balance strain point, femoral lateral balance strain point, lower leg lateral balance strain point, each trunk strain _{point, PB UA, PB FA, PB} FL, PB CL, when the PB _T, they PB _UA = | (IR _LUA + IR _RUA ) / 2-100 |
PB _FA = | (IR _LFA + IR _RFA ) / 2-100 |
PB _FL = | (IR _LFL + IR _RFL ) / 2-100 |
PB _CL = | (IR _LCL + IR _RCL ) / 2-100 |
PB _T = | TMM / TMM _I -1 | × 100
Is calculated.

The total left / right balance is also converted into points as follows.
BL _SUM = BL _UA + BL _FA + BL _CL + BL _FL
PB _SUM = | BL _SUM |

The left-right distortion point PD _LR is obtained by rounding the BL _SUM obtained here to the second decimal place and converting it to a point.

These points are displayed on the right side of the extremity muscle mass evaluation display section A2 (FIG. 5). Displayed here are balance distortion points of left and right muscle mass, PB _UA , PB _FA , PB _FL , and PB _CL . In this example, the subject (or trainer or advisor) determines that there is a large difference between the current muscle mass and the ideal muscle mass, particularly in the forearm.

Next, the calculation method of comprehensive evaluation is demonstrated using FIG.11 and FIG.12. As shown in FIG. 12, the comprehensive evaluation is from “AAA” to “J”. In this example, the strain points of each body part, that is, the upper arm strain point PD _UA , the forearm strain point PD _FA , the thigh strain point PD _FL , the lower leg strain point PD _CL , the muscle mass strain point PD _T , and the left and right strain point PD _LR are totaled. The overall evaluation is determined by the number of points. Here, if the total distortion points are PD _ALL ,
PD _ALL = PD _UA + PD _FA + PD _FL + PD _CL + PD _T + PD _LR
It becomes. For example, assuming that the total number of balance points is 71 points, the determination “B” corresponding to the lower limit 60 and the upper limit 75 is displayed as a comprehensive evaluation as shown in FIG. Here, only the comprehensive evaluation determination method has been described. Similarly, a program for displaying the other display items in FIG. 5 in an easy-to-understand manner for the subject is provided and is appropriately determined using the above-described numerical values. The result is displayed.

FIG. 13 is an example of another program. Here, based on PD _ALL calculated as described above, a corresponding message is displayed. For example, if the total points are 71 points, the message corresponding to the lower limit 61 and the upper limit 81 “Slightly out of balance. Appropriate advice from the trainer is required” is selected, and the limb muscle distribution balance evaluation display part A3 (FIG. 6).

  FIG. 7 shows details of the upper and lower body balance evaluation display part A4. Here, as described above, from the balance points calculated from the muscle mass of each part of the body, the program makes an appropriate determination, and “balance evaluation”, “exercise evaluation”, “exercise attention”, “ A message about “exercise event” is displayed. From this message, the subject can objectively know his / her muscle balance, and can exercise to improve the ideal muscle balance while paying attention to the exercise method.

  FIG. 8 shows details of the extremity muscle mass display section A5. Thus, if the balance of the muscle mass of each body part is displayed with a body model diagram, it will be easier to understand. Moreover, as shown in FIG. 9, it can also be displayed in a radar chart diagram A6. In this radar chart, the body is displayed in a nine-sided shape with the trunk right above, the left and right upper arms, the left and right forearms, the left and right thighs, and the left and right lower legs as vertices. Is clearly understood at first glance.

Note that “self-evaluation” in FIG. 9 is the measured muscle mass of each part. The standard value is a value obtained by subtracting 10% from the ideal muscle mass. That is, when the standard muscle mass of each of the upper arm, forearm, thigh, lower leg and trunk is MM _SUA , MM _SFA , MM _SFL , MM _SCL , MM _ST ,
MM _SUA = MM _IUA × 0.9
MM _SFA = MM _IFA × 0.9
MM _SFL = MM _IFL × 0.9
MM _SCL = MM _ICL × 0.9
MM _ST = MM _IT × 0.9
It is.

The above is the result of performing various calculations using the 9 muscle masses measured by the body composition measurement / advice device, and this device displays more detailed muscle masses based on these values. Can be calculated. The muscle mass of these detailed parts is calculated using the “Aquis-type chain equation”. The Aquis-type chain equation is a series of equations created in consideration of the chain reaction of the muscle movement, the load on the entire posture, and the burden of each limb, and an example is shown below.
[1] Stopping equation When calculating the muscle mass of the pectoral muscle, it is approximated as a function of the muscle mass of the forearm, upper arm, and trunk.
[2] Anti-gravity muscle and antagonistic muscle type equations When calculating the muscle mass of the back muscle, approximate it as a function of the muscle mass of the trunk and pectoral muscles.

Here, four examples are used to explain the Aquis chain equation, but the approximate muscle mass can be calculated for the other muscle sites in the same combination.

FIG. 10 is a balance radar chart for each type of exercise. Based on the detailed muscle mass of the body obtained by the Aquis-type chain equation, the maximum muscle strength estimated from the current muscle mass and the maximum muscle strength estimated from the ideal muscle mass are calculated for each exercise item. Further, as shown in the following equation, a value obtained by dividing the estimated maximum muscle strength for each current exercise type by the estimated maximum muscle strength for each ideal exercise type is displayed on the radar chart diagram.
B = ([estimated maximum muscle strength by current exercise type] / [estimated maximum muscle strength by ideal exercise type]) × 100
Here, B is the balance value of [estimated maximum muscle strength by current exercise type] and [estimated maximum muscle strength by ideal exercise type].

  A method for creating an exercise menu that is advice to the subject based on the detailed muscle mass of the body and the estimated maximum muscle strength obtained by the Aquis-type chain equation will be described. FIG. 14 is an exercise menu creation screen. Detailed display contents of each part B1 to B5 of the exercise menu creation screen B are shown in FIGS.

  In the exercise menu, various muscle training devices (or methods) are specifically listed and their target values are described. For example, in the example of FIG. 15, training apparatuses / methods of a bench press, an upright, a rat machine F, a low pulley, a lek ix, and a 45-degree leg press machine are employed.

  The value of each item of these exercise menus is calculated based on the detailed muscle mass obtained above. Specifically, for each exercise category, the maximum muscle strength estimated from the current muscle mass, the maximum muscle strength estimated from the ideal muscle mass, and the maximum muscle strength estimated from the ideal muscle mass are estimated from the current muscle mass. A value obtained by dividing the value by dividing the muscle strength, the maximum muscle strength estimated from the target muscle mass, and the maximum muscle strength estimated from the target muscle mass by the maximum muscle strength estimated from the current muscle mass is calculated, and the exercise type shown in FIG. It displays on another estimated maximum strength table.

  When determining the training weight using general training theory, the first set is 30% of the estimated maximum strength for each current exercise type, the second set is 40% of the estimated maximum strength for each current exercise type, and the third set is It is calculated by the method of 50% of the estimated maximum muscular strength by the current exercise type and the fourth set by 60% of the estimated maximum muscular strength by the current exercise type. In the program using the method of the present invention, a training weight is calculated for each exercise type as a reference value by estimating from the estimated maximum muscle strength for each current exercise type and the estimated maximum muscle strength for each ideal exercise type. For this reason, it is possible to realize a training menu that does not apply excessive load on muscles by calculating as a low load for those exercise types where the estimated maximum muscle strength by current exercise type and the estimated maximum muscle strength by ideal exercise type are close. it can.

  The program calculates the training weight for each exercise item as a reference value. FIG. 21 shows a calculation example for calculating the weight for each exercise item. The calculation result is reflected in the weight of FIG. 15, and the subject may perform training according to the set weight.

  In the program of the present invention, not only the exercise type of the “basic enhancement menu” is selected, but also the exercise type such as “basic loosening menu” and “personal exercise flexibility” are displayed as shown in FIGS. By incorporating these exercises into the training, the subject can balance not only the muscle mass but also the muscle flexibility. As for the weight setting in the case of these exercise events, the result automatically calculated by the program is displayed as described above.

The balance radar chart B4 for each exercise type (FIG. 18) displays the result of calculating the strain value obtained from the above-described estimated maximum muscle strength for each current exercise type and the estimated maximum muscle strength for each ideal exercise type. This distortion value D is obtained by the following equation.
D = 1 − ([Estimated maximum muscle strength by ideal exercise type] / [Present maximum muscle strength by current exercise type])

  Such training is preferably performed twice a week for about 60 minutes, and it is desirable for the subject to be aware of the correct form during training. The body composition is measured approximately every one and a half months, and the effect of improving the balance of muscles in each part of the body can be confirmed. Based on this result, an exercise plan is created again and training is performed according to the plan. By repeating this cycle, the subject can realize an ideal balance of muscle mass in each part of the body without burdening the extra muscles.
