Japanese Patent Laid-Open No. 11-128395 JP-A-6-154355

  In the conventional apparatus of this type, the exercise load is determined in consideration of the transient physical data of the exerciser, and an apparatus for determining the exercise load in consideration of the exerciser's current situation in more detail is desired.

  In addition, since it is basically designed for healthy individuals with normal limb movements, it is difficult for non-healthy people with paralysis or orthopedic disease to respond, and it is also desirable to support non-healthy people.

  An object of the present invention is to provide a control device for a fixed exercise load device and a control method therefor that determine an exercise load that is more suitable for the present situation of the exerciser from more diverse information of the exerciser.

  The present invention relates to a control device for a fixed exercise load device that allows an exerciser to exercise with a load generated by the exercise device, and is based on a database storing various standard data and exerciser information on the physical functions of the exerciser. An exercise intensity calculation unit for calculating exercise intensity indicating the magnitude of the exercise load of the exercise apparatus, exerciser information including information on exercise habits of the input exerciser and the corresponding standard data in the database. An exercise time calculation unit that calculates exercise time in the apparatus, and an exercise load control unit that sends a control signal to the load control device of the exercise apparatus based on the calculated exercise intensity and exercise time. It is in the control device of the fixed exercise load device.

  In the present invention, an exercise load more suitable for the current state of the exerciser is determined from more diversified information about the exerciser.

  First, in conventional exercise prescription and lifestyle guidance, exercise, lifestyle, and meals were often individually taught. However, in diversifying lifestyles, it is not always possible to easily carry out exercises according to the contents of each instruction, improvement of lifestyle, and improvement of the amount and quality of meals.

  Moreover, in the evaluation of the physical function used for exercise prescription, the cardiopulmonary endurance by the cardiopulmonary function (maximum oxygen intake) is examined exclusively by the exercise load test. However, in order to measure the maximum oxygen intake, for example, exercisers are equipped with a mask for measurement and exercise, and many measurement facilities are provided. It was very troublesome.

  That is, it is desired to perform exercise prescriptions taking into account comprehensive lifestyle habits including exercise and meals, and exercise prescriptions based on physical functions (physical fitness test indices) that can be obtained more easily. Furthermore, it is desired to provide an exercise prescription that takes into account the characteristics of motor functions of non-healthy individuals with paralysis and orthopedic diseases, and a control device for a fixed exercise load device that realizes exercise based on the exercise prescription. .

For example,
・ `` Estimation of workload for anaerobic threshold by maximal isokinetic leg extension power '', Yamada et al. (St. Marianna University School of Medicine, Department of Rehabilitation), Japan Cardiovascular Journal, The Japanese Circulation Society, 2005, Vol.56, Special Issue IA, 65th Annual Meeting of the Japanese Circulation Society, p112, OE043,
・ "Relationship between maximum effort exercise and ventilatory work threshold", Yuri et al. (Hokkaido University Hospital Rehabilitation Department), Hokkaido Physical Therapist Journal, 2005, Vol. 22,
For example, the optimal exercise work threshold obtained by measuring and evaluating cardiopulmonary function in an exercise test using an exhaled gas analyzer is the maximum leg extension force (ergometer) that can be measured easily compared to this exercise test. It is suggested that the optimal exercise work threshold is estimated from the maximum leg extension force.

  Therefore, in the present invention, based on the above-described research report, the maximum leg strength, which is the maximum leg extension force, is measured or input as a result of measurement by another device, and multiplied by a predetermined estimation coefficient considering the above-described research report. Set the value as the optimal exercise intensity.

  As for the exercise time, the product of the exercise intensity and the exercise time becomes the calorie consumption in the exercise, which is a measure of the exercise amount such as obesity elimination.

  Therefore, in the present invention, when the exerciser has a large amount of calories in view of the body fat percentage of the person who exercises and the degree of obesity such as BMI (Body Mass Index), the exercise time is lengthened and the extra intake calories are consumed. A judgment process is provided.

As another research report,
・ `` Effects of low-intensity aerobic training on the high-density cholesterol concentration in healthy elderly subjects ''), Y. Sunami et al., Metabolism, 1999, 48 (8): 984-8,
There is a correlation between the exercise time per week and the amount of immune substance in the blood (for example, anti-arteriosclerotic substance), and the target exercise time per week is estimated.

  Therefore, in the present invention, for those who have less exercise time per week and who do not have exercise habits, a determination process for increasing the exercise time to reach the target exercise time is provided.

Also, "One leg-driven exercise therapy by StrengthErgo240 for thigh amputees", Sakagami et al. (University of Tokyo Hospital), Physical Therapy, Japan Physical Therapists Association, 2004, Vol.31, Special Issue N0.2 , 2004, 39th Japan Physical Therapy Congress, Vol. 31, Special Issue No. 2, p160,
As described in this study, in the case of an exerciser who has a movement disorder that is difficult to exercise with a normal exercise device, such as a single leg thigh amputee, add a passive movement function as described in this research report. Can continuously exercise.

  Therefore, in the present invention, processing determination for automatically enabling the passive motion function is added by setting whether or not continuous motion is difficult by itself.

With the above functions, the optimal value for exercise intensity is determined by the strength of the maximum lower limb muscle strength, and the optimal value for exercise time is determined by the length of exercise time per week and the amount of calories consumed. Ask.
In addition, for exercisers who are unable to move smoothly due to the presence or absence of paralysis or orthopedic disease, the exercise prescription is determined to assist the movement by moving the exercise device to make it move dynamically. And set.
Furthermore, by providing a function that can determine the exercise intensity at which the effect of reducing body fat can be expected based on the results obtained in advance through research or the like, a function for calculating and determining that the minimum exercise intensity is higher than this, Provide an exercise prescription that can effectively reduce body fat.

Hereinafter, the present invention will be described according to specific embodiments.
Embodiment 1 FIG.
FIG. 1 is a block diagram schematically showing an example of the configuration of a fixed exercise load device provided with a control device according to the present invention. The exercise device 7 including an ergometer or a fitness exercise device includes a pedal device 7a provided with a pedal 70, and a motor 7b that applies a rotational load to the pedal device 7a or performs a rotation operation. The rotational speed of the pedal device 7 a is detected by a rotational speed detector 5 that is an operation state detector of the exercise device 7. The rotational load and rotational torque generated by the motor 7b are controlled by the load control device 6.

  The control device 1 constituted by a computer is operated from sensor equipment such as exerciser information input from the input device 2, exercise load calculation related information that is various reference data stored in the database 3, and the rotational speed detector 5. The exercise load is calculated and determined according to the state detection information to control the load control device 6 and various information is displayed on the display device 4. The control device 1 includes an exercise intensity calculation unit 101, an exercise time calculation unit 102, an exercise assist function addition determination unit 103, an exercise load control unit 104, a maximum lower limb muscle strength measurement unit 105, and an exercise effect estimation unit 106, which are shown as functional blocks. . The exercise intensity indicates the intensity of exercise load on the exercise device 7.

  The database 3 includes a standard exercise time data table 300, a standard intake calorie data table 301, a standard body weight / body fat percentage data table 302, and a driving intensity-time standard exercise effect data table 303. These databases statistically collect a large amount of data collected in advance by experiments or the like, and can search for desired data using predetermined factors (in some cases, a plurality of types) as key data.

  FIG. 2 shows a flowchart for explaining the operation according to the first embodiment of the present invention, and the operation will be described below. From the input device 2, for example, sex S, age A, weight WE, height H, body fat percentage F, maximum lower limb strength data Tmax (N.m) regarding physical functions, exercise habit data per week (exercise Time) tetc (sec), device usage frequency data per week (usage frequency) N (time), daily (meal) calorie intake data (calorie intake) K (kcal), physical motor function disease presence / absence data X Are input as exerciser information.

<Exercise intensity setting>
When the maximum lower limb strength Tmax (N.m), which is the exercise function information of the exerciser, is input to the exercise intensity calculation unit 101 (step S1), a predetermined coefficient k1 (for example, arbitrarily set to the maximum lower limb strength Tmax) (for example, Torque value multiplied by 20%) T1 (Nm) = Tmax (Nm) × k1
Alternatively, the work amount W1 obtained by multiplying the torque value by a predetermined rotation speed ω1 (for example, 50 rpm) arbitrarily set.
W1 (W) = T1 (N.m) × ω1 (rpm) /9.55
9.55: Exercise intensity calculation for obtaining a conversion coefficient is performed (step S2). Then, the obtained torque value T1 or work amount W1 (torque × rotational speed) is set as the exercise intensity, and is temporarily stored, for example, in the storage unit M (step S3). Both the torque value T1 and the work amount W1 may be set and selected according to the exercise load control mode of the fixed exercise load device.

  The maximum lower limb muscle strength Tmax can also be measured by the exercise device 7. This is performed by the maximum leg strength measurement unit 105. For example, when a maximum lower limb strength measurement instruction is input from the input device 2, the maximum lower limb strength measurement unit 105 displays on the display device 4 to urge the athlete to pad the pedal device 7 a with full power to measure the maximum lower limb strength. To do. For example, the exercise intensity (torque) in the exercise device 7 is gradually weakened, and the start of rotation of the pedal device 7 a is detected by the output of the rotation speed detector 5. The value of the torque command given to the load control device 6 at the start of rotation is taken as the maximum lower limb muscle strength Tmax.

<Exercise time setting>
The exercise time calculation unit 102 receives the exercise (cumulative) time tetc (sec) per week and the number N (times) of use of the exercise load device per week (steps S4 and S5). As an example, the target exercise time is set to 300 (minutes / week), and the exercise time tx per time by the load device is set,
tx = (300−tetc) ÷ N
Asking. As an example, set the minimum exercise time to 20 (minutes / times)
If tx ≦ 20, tx = 20 is set (step S6). When the addition time described later is not taken into consideration, this tx is set as an exercise time and is temporarily stored in the storage unit M, for example.

  As for the target exercise time, the exercise time calculation unit 102 obtains the standard exercise time tref from the standard exercise time data table 300 stored in the database 3 based on, for example, the sex S, age A, etc. of the exerciser similarly input. This may be the target exercise time.

  The above steps S4 to S6 relate to the setting of exercise time considering exercise habits, but the following steps S7 to S9 are performed when eating habits are also considered.

  When the calorie intake K (kcal) per day is further input to the exercise time calculation unit 102 (step S7), the standard calorie intake data table stored in the database 3 based on the same sex S and age A input in the same manner. It is determined whether or not the standard intake calorie Kref obtained from 301 is exceeded. If the calorie intake K exceeds the standard calorie intake Kref, the exercise addition time tex is obtained based on the exercise addition time for the unit intake calorie. The standard intake calorie data table 301 is a data table for searching for standard intake calories using gender S and age A as factors.

  When the intake calories are excessive, for example, it is assumed that the exercise time is added in advance for 5 minutes for every 500 kcal intake calories. If the calorie intake K> 2500 kcal while the standard calorie intake Kref = 2500 kcal, the exercise addition time tex = 5 (minutes) × (2500 ÷ 500) = 25 minutes. Further, an upper limit of the exercise addition time, for example, a maximum of 60 minutes is provided (step S8). Then, the exercise time tx = the exercise time tx + the exercise addition time tex obtained by adding the exercise addition time tex is set and stored (step S9).

<Exercise load control>
The exercise load control unit 104 controls the load while monitoring the rotation speed signal from the rotation speed detector 5 according to the exercise intensity (torque value T1 or work amount W1) set in the storage unit M and the exercise time tx. A control signal is sent to the device 6 to drive the exercise device 7 to cause the exerciser to exercise. When the exercise intensity is set by the work amount W1, the torque is adjusted with respect to the rotation speed.
Further, if necessary, the display device 4 displays the exercise intensity T1 or W1, the exercise time tx, the remaining exercise time, whether exercise is performed as set, and the like.

<Exercise support function addition judgment>
In addition, the exercise support function addition determination unit 103 notifies the exercise load control unit 104 of the addition of the exercise support function when the diseased physical motor function disease presence / absence data X is input. The exercise load control unit 104 causes the load control device 6 to rotate the motor 7b to rotate the pedal device 7a when the rotation speed signal from the rotation speed detector 5 becomes zero or less than a predetermined value within the set exercise time tx. Rotate and send a control signal that causes the exerciser to passively move until the set exercise time tx.

<Modification of exercise intensity and exercise time based on standard body weight / body fat percentage>
The standard body weight / body fat percentage data table 302 of the database 3 is a data table for searching for the standard body weight or body fat percentage using, for example, sex S, age A, and height H as factors. The exercise intensity calculation unit 101 and the exercise time calculation unit 102 search the standard body weight / body fat percentage data table 302 based on the input sex S, age A, and height H to obtain the standard body weight WEre or the standard body fat percentage Fre. When the input body weight WE or body fat percentage F is larger than the standard body weight WEre or standard body fat percentage Fre, respectively, the determined exercise intensity T1 or W1 and the exercise time tx are respectively multiplied by a predetermined coefficient k2 to exercise. You may make it increase intensity | strength and exercise time.

<Exercise intensity-Correction of exercise intensity and exercise time based on time standard exercise effect>
Further, the exercise intensity-time standard exercise effect data table 303 of the database 3 shows, for example, for each sex S and age A, the standard exercise effect for each set of exercise intensity and exercise time as a decrease rate of weight or body fat percentage. Database. The exercise load control unit 104 searches the exercise intensity-time standard exercise effect data table 303 for the standard exercise effect in the set of the entered sex S, age A, and the set exercise intensity and exercise time, and the weight or body. When the reduction rate of the fat percentage is less than a predetermined value, the exercise intensity may be increased to an exercise intensity at which the reduction rate is equal to or greater than a predetermined value, and exercise load control may be performed with the increased exercise intensity.

  The exercise load control unit 104 may increase exercise time instead of exercise intensity until an exercise time at which the decrease rate is equal to or greater than a predetermined value, and perform exercise load control with the increased exercise time.

<Exercise intensity-Time standard exercise effect display>
In addition, the exercise effect estimation unit 106 obtains a standard exercise effect based on the input sex S, age A, and the combination of exercise intensity and exercise time finally determined by the exercise load control unit 104, and exercise intensity-time standard exercise. Search the effect data table 303. In the exercise intensity-time standard exercise effect data table 303, the standard exercise effect is expressed as a decrease rate (for example, x% / 3 months) of the body weight or body fat percentage after a predetermined period when the exercise intensity-time exercise is continued as it is. Storing. The exercise effect estimation unit 106 multiplies the input weight WE and the body fat percentage F by the weight after the predetermined period or the decrease rate of the body fat ratio obtained in the standard exercise effect data table 303 to obtain the estimated weight after the predetermined period, Calculate the estimated body fat percentage. And this is made to display on the display apparatus 4 in order to improve an exerciser's motivation.

  In addition, the period regarding the exercise habit data per week and the daily calorie intake data is not limited to this, and a desired period may be set for each period.
