Description

  The present invention relates to a training device in which an individual exercises to improve physical fitness.

Conventionally, various training devices for an individual to exercise with an appropriate load have been proposed. Among various training devices, there are devices that perform repeated exercises by applying a load to the muscles in order to train the target partial muscles. For example, Patent Document 1 discloses an apparatus for training by repetitive exercise. This training device uses a direct drive motor as a muscle load providing source, and describes a muscle load providing device that adjusts the load by controlling the rotation of the direct drive motor according to the torque or rotational speed of the direct drive motor. Yes.
Japanese Examined Patent Publication No. 7-41083

  The load control method described in Patent Document 1 is a method of adjusting the load by controlling the rotation of the direct drive motor in the same manner for any trainee. However, there are actually differences in the body shape of each individual trainee. The difference in body shape is, for example, a difference in amplitude and rotation width of repetitive motion. Therefore, the posture that the trainee takes when the rotational speed of the direct drive motor is a predetermined constant value V1 varies depending on the trainee. Nonetheless, if the load according to the torque or rotational speed of the direct drive motor is applied uniformly to any trainer, it will be just the right load control for a trainer of standard body type. For a trainer who is smaller than a standard body or a trainer who is large, the change in load becomes inappropriate. As a result, the trainee cannot exercise properly, resulting in the effect of exercise not being sufficiently improved or forced exercise.

  An object of the present invention is to provide a training device that allows a trainee to exercise with a load according to the body shape of each trainer in the forward and return trips of the repetitive exercise.

In order to solve the above-mentioned problems, the present invention 1 provides a training apparatus that is used for exercise by applying a load to a movable part capable of repetitive movement with an electric load generator. This apparatus has the following means.
A movable range determining means for determining a movable range that is a range in which the movable portion repeatedly moves according to a trainee;
An acquisition means for acquiring personal data of the trainee;
Reference load determination means for determining a reference load calculated based on a maximum of 1 RM included in the personal data of the trainee ,
Load control means for controlling the load applied to the movable part by the load generator according to the determined position within the movable range and a reference load so that the load is heavier than the reference load at the end of the movable range .

  Since the trainee's physique is reflected in the range of motion, by changing the load according to the position within the range of motion, it is possible to apply a load that suits the trainee's physique and allow the trainee to exercise effectively. The range of motion is preferably determined by measurement. This is because the range of motion obtained by measurement reflects the physique of the trainee and the softness of the joints. The range of motion according to the trainee is measured at least once for each trainer, preferably continuously and intermittently. For example, it may be measured every predetermined period, or may be measured before or at the start of each exercise. If measurement of the range of motion is performed before or at the start of exercise every time, it is possible to apply a load that suits the condition of the trainer who changes from day to day, and the appropriateness of the exercise is improved.

  The method for changing the load is not particularly limited. For example, in an abdominal muscle exercise in which the upper body is tilted forward, a reference load is applied at the start end of the forward path, and an end load (end load> reference load) is applied at the end of the forward path. At the end of the forward path of forward bending exercise, it is easy for the trainer to apply strength to the abdominal muscles, and training becomes easier, so by increasing the load by that amount, the training effect can be achieved throughout the repeated exercises. It can be maintained at approximately the same level, and trainers can perform effective training. In addition, for example, in the barbell exercise, it is possible to increase the load at the middle of the forward path. A reference load is applied at the start and end of the forward path, and a reference load × N (1 <N <2) is applied in the middle of the forward path. By applying a strong load at the sticking point in the barbell exercise, the target muscle can be stimulated effectively.

The invention 2 is the invention 1, wherein the load applied by the load control means is greater than or equal to the reference load determined by the reference load determination means and N times the reference load (1 <N <2). Adjust to gradually change between:
Since the load curve is determined based on the range of motion and the reference load, the reference load is preferably determined by measurement. For example, 1RM of the trainee is measured, and a value obtained by multiplying the measured 1RM by a predetermined coefficient is used as the reference load. Of course, instead of measurement, the weight, sex, age, body fat percentage, etc. of the trainee may be associated in advance with the reference load, and the reference load may be determined based on the physical personal data of the trainee. The above load curve includes a change in load that changes in a straight line. That is, a case where both the forward path and the return path of the movable part change linearly is included.

  A third aspect of the present invention provides the training apparatus according to the second aspect of the present invention, further comprising a long and variable power transmission member that transmits the load of the load generator to the movable portion. In this device, the load control means is movable at the same position on the return path of the reciprocating motion rather than the load generated by the load generator with respect to the movable portion at an arbitrary position on the forward path of the reciprocating motion. The load generated by the load generator is increased. The increase in the load on the return path is adjusted to correspond to the load reduced by the dynamic friction force generated by the power transmission member on the return path.

The magnitude of the load generated by the motor is changed between the forward path and the return path. For example, in a training apparatus for abdominal muscle exercises performed by tilting the upper body forward, consider a configuration in which a motor is used as a load generator and a load is applied to the movable part by connecting the motor and the movable part with a chain.
In the forward path, a dynamic frictional force f is generated at the connecting portion of the chain structure. The dynamic friction force f is generated when the trainee tries to tilt the movable part forward and is generated in a direction opposite to the direction in which the object is moved. Due to the dynamic friction force f, the total load F1 experienced by the trainee is the sum (M1 + f) of the load M1 applied to the movable part by the motor and the dynamic friction force f.

  On the return path, the trainee performs a motion of raising the upper body while gently pushing back the movable part to return to the near side. At this time, the total load F2 experienced by the trainee is lighter than the load M2 applied to the movable part by the motor. This is because the motor always applies a load in the direction of pushing up the movable part. Therefore, when the loads M1 and M2 applied to the movable part by the motor have the same value, the load on the return path becomes lighter than that on the outbound path. Therefore, the value of the load applied by the motor on the return path is, for example, M2 = (M1 + 2f), and the load applied by the motor is changed between the forward path and the return path. The magnitude of the load of 2f is, for example, about 5 kg. As a result, the trainee can experience a substantially uniform load on the forward path and the return path.

Invention 4 is the invention 2 or 3, wherein the load control means linearly increases the load of the movable part moving from the start end to the end of the repetitive motion in accordance with a change in the position of the movable part, There is provided a training device that linearly reduces the load of the movable part moving from the end of the repetitive motion to the start end in accordance with a change in the position of the movable part.
For example, in the abdominal muscle exercise, the load increases as the upper body is tilted forward, and the load decreases as the upper body is raised. Even in this case, when the motor and the movable part are connected by the chain structure, a load that is heavier in the forward path than the return path is applied to the movable part by the load generator in consideration of generation of the dynamic friction force f. Can do. Further, when the load change is linear in this way, the design of the load control can be facilitated. That is, as will be described in detail later, the change in the load can be uniquely determined based on the reference load, the final load, and the trainee's range of motion data.

A fifth aspect of the present invention relates to the first aspect of the present invention, wherein the load control means is configured such that a load that is substantially reduced by the weight of the trainee applied in a direction against the movement of the movable portion is a weight offset load. Provided is a training device that adds the weight-canceling load to a load applied to the movable part according to a position.
Appropriate stimulation can be applied to the target muscle by applying the load in consideration of the influence of the body weight in a posture where the weight can be a resistance to the load. For example, in the abdominal muscle exercise, the more the upper body is defeated, the more the weight of the upper body works as a resistance to the load. Therefore, if the angle from the horizontal position to the upper body (actually a movable part such as a bar) tilted upward from this position is θ, the weight offset load can be set to weight × a × cos θ. Yes (0 <a <1). Actually, the formula for calculating the weight offset load and its value vary depending on the training type and the structure of the training device.

  A sixth aspect of the present invention provides the training apparatus according to the first aspect of the present invention, further comprising selection receiving means for receiving a selection from among a plurality of training types of the invention. In this apparatus, the load control unit includes a load pattern storage unit that stores a training type and a load change pattern in association with each other, and the movable unit is based on the change pattern corresponding to the selected training type. Change the load applied to.

  Depending on the training type, the load can be changed. Thereby, in each kind of exercise | movement, a load can be changed effectively and an exercise effect can be improved. For example, in the case of the abdominal muscle exercise, the load is linearly increased on the forward path and the load is linearly decreased on the return path. In the case of barbell motion, the load is once increased linearly on the forward path and then decreased linearly, and the load is maintained at a constant value on the return path.

  Since the load can be changed according to the body shape of the trainee by using the present invention, the exercise effect of each trainer can be enhanced.

<Outline of the invention>
In the training apparatus according to the present invention, a load is applied to a bar (corresponding to a movable part) that repeatedly moves by the exercise of a trainee by a motor. The load applied by the motor varies rather than constant during repetitive movements. The repetitive motion width, that is, the width of the range of motion of the bar reflects the difference in the physique of individual trainees and the flexibility of the body. Therefore, by changing the method of changing the load according to the width of the range of motion, it is possible to apply a load that suits the trainee's physique and body and make the trainee perform an effective exercise.

<First Embodiment>
《Configuration of training device》
FIG. 1 is an explanatory diagram showing a hardware configuration and a functional configuration of a training apparatus 100 according to the first embodiment of the present invention. With reference to FIG. 1, the hardware configuration and the functional configuration of the training apparatus 100 will be sequentially described.

(1) Hardware Configuration (1-1) Overall Configuration The training device 100 is installed in a store, for example, and connected to the server 200 in the store. The server 200 accumulates the personal data of the trainee and transmits it in response to a request from the training apparatus 100. In the present embodiment, the server 200 is installed only in the store, but an off-store server (not shown) that connects in-store servers throughout the country or around the world may be provided. Member data may be stored in such a server outside the store, and the server of each store may access it.

  The training apparatus 100 includes a torque motor 15 (corresponding to a load generator), a motor signal processing unit 23, a sensor 24, a control unit 30, an input unit 50, a monitor 70, and a speaker 90. The torque motor 15 applies a load to a bar (described later). The motor signal processing unit 23 transmits the rotation direction, rotation speed, number of rotations, and the like of the torque motor 15 to the control unit 30. The sensor 24 is provided at a predetermined location of the training apparatus 100 and detects, for example, the orientation of a seat (described later). The control unit 30 is a computer including a CPU, a ROM, a RAM, a hard disk, and the like. Details of the function of the control unit 30 will be described later. The input unit 50 has a function of receiving data input, and can be realized by, for example, a transponder receiving unit, a numeric keypad unit, or a card reader. The monitor 70 and the speaker 90 function as a notification unit for information such as exercise guidance and announcement for the trainee, and output images and sounds according to programs stored in the control unit 30.

(1-2) Example of Training Device FIGS. 2 and 3 are examples of the appearance of the training device 100. In this example, in the training apparatus 100, a trainee sitting on the seat 16 causes the bar (corresponding to the movable portion) 11 to perform a repetitive motion centering on the rotation axis, so that the abdominal muscles, back muscles, and left and right flank muscles It has a structure that can be trained.

  The bar 11 is rotatable around a rotation axis and is connected to the chain 13. The chain 13 is hung on two pulleys 14a and 14b. The pulley 14b shares the rotating shaft with the torque motor 15. When the trainee rotates the bar 11, the chain 13 moves, thereby causing the pulleys 14a and 14b to rotate. At this time, the torque motor 15 applies a torque to the pulley 14 b and applies a load to the bar 11. A servo motor, a stepping motor, or the like can be used instead of the torque motor. Further, a load may be applied to the bar 11 using an electromagnetic brake or the like instead of the motor.

  The sheet 16 is rotatable between the A direction and the B direction in the drawing. In the figure, the A direction is perpendicular to the B direction. The trainee exercises in the direction A or B in the figure. In the first position in which the seat 16 faces the direction A as shown in FIG. 2, the trainee puts the foot on the footrest 17a, holds the bar 11 and moves forward with the upper body, or pushes the bar 11 back. Do the back muscle movement to push up. In the second position in which the seat 16 faces in the direction B in FIG. 2, the trainee puts his / her foot on the footrest 17b and holds the bar 11 under the left arm and pushes down or pushes the bar 11 under the right arm. Hold the right flank and hold it down.

A sensor 24 (see FIG. 1) is provided below the sheet 16, detects the direction of the sheet 16, and transmits a detection signal to the control unit 30.
The stopper 40 is provided for setting a limit point of mechanical movement of the bar 11 at each training. By setting a limit that can be mechanically moved with the stopper 40 for the range of motion assumed during training, avoid sudden movements of the trainee or avoid overloading the body due to excessive movement. can do. Although omitted in the drawing, the limit point of mechanical movement of the bar 11 is set in advance according to, for example, the abdominal muscle movement, the back muscle movement, and the left and right flank movement. Changing the limit point setting is done manually by the trainee. When the stopper 40 is pulled up, the fixed state of the stopper 40 is released. When the lever is moved to each limit point, the stopper 40 is pulled downward and fixed at that point. The position of the stopper 40 shown in FIG. 2 or FIG. 3 is a setting for training the back muscle exercise.

  In the abdominal muscle exercise and the left and right flank exercises, the more the body is tilted forward or laterally, the easier it is to apply force to the abdominal muscles or flank muscles. . Furthermore, as the upper body falls, the weight of the upper body becomes a resistance force that pushes down the bar 11, and works to help muscle strength. Therefore, in the abdominal muscle exercise and the left and right flank exercise, the load is changed so that the load increases as the bar 11 is pushed down. Details of how to change the load will be described later.

(2) Functional configuration (2-1) Control unit Next, functions of the training apparatus 100 will be described. The function of the training device 100 is realized by the control unit 30. Referring to FIG. 1 again, the control unit 30 will be described in detail. The control unit 30 has functions shown in the following (a) to (f).
(A) Detection signal processing unit 31: Processes detection signals from the motor signal processing unit 23 and the sensor 24 and sends them to the calculation unit 36.
(B) Receiving unit 32: Receives an input signal such as personal data input by the input unit 50 and sends it to the calculation unit 36.
(C) Communication control unit 33: Sends and receives personal data to and from the server 200.
(D) Image generation unit 34: Generates display data on the monitor 70.
(E) Audio control unit 35: Generates audio data to the speaker 90.
(F) Arithmetic unit 36: A program stored in a ROM (not shown) or the like is executed to control each unit in the control unit 30.

(2-2) Calculation Unit The calculation unit 36 includes a movable range determination unit 36a, a load control unit 36b, a reference load determination unit 36c, a selection reception unit 36d, and a training information processing unit 36e. The load control unit 36b further includes a load pattern storage unit 36b-1. Hereinafter, functions of each unit will be described.
(2-2-1) Personal Data FIG. 4 is a conceptual explanatory diagram of personal data acquired from the server 200 by the training information processing unit 36e. Since each function described later is realized based on the personal data, the personal data will be described prior to the function of each unit.

  The personal data includes a trainee ID, basic personal data, and additional personal data. The trainer ID is an identifier for identifying a trainee. Basic personal data is the physical information of the trainee such as gender, age, weight, and body fat percentage. The basic personal data includes information necessary for determining an estimated 1 RM (repetition maximum) described later. The additional personal data is, for example, 1RM (repetition maximum) and the movable range of the bar 11, and is stored for each training type. The additional personal data is acquired by the training device 100 by measurement and transmitted to the server 200. When the training type 1RM to be executed and the movable range are measured, the load curve is determined based on the reference load and the movable range obtained from the 1RM. Conversely, when there is no additional personal data of the training type to be executed, an estimated 1RM is calculated based on the basic personal data, and the range of motion is measured immediately after the start of training. Then, a load curve is determined based on the reference load and the range of motion obtained from the estimated 1RM. Details of the determination of the load curve will be described later.

(2-2-2) Selection Accepting Unit The selection accepting unit 36d accepts selection of various modes and training type described later. FIG. 5 shows an example of a menu screen output to the monitor 70 by the selection receiving unit 36d. The menu screen accepts selection of any of various modes. In this figure, the measurement mode (“muscle strength measurement mode” in the figure) is selected. In the measurement mode, 1RM, which is additional personal data, and a movable range are measured for each training type. In addition, the menu screen accepts selection of each mode of “rhythm shape”, “manual”, “circuit training”, “slow training”, and “muscular endurance measurement”. Furthermore, although not shown, in any of the “muscle strength measurement mode”, “rhythm shape”, “manual”, “circuit training”, and “slow training” mode, the selection receiving unit 36d selects the training type. Accept. In this training apparatus 100, the training type is abdominal muscle exercise, back muscle exercise, right flank exercise, or left flank exercise.

(2-2-3) Training Information Processing Unit The training information processing unit 36e executes input reception of basic personal data, explanation of training processing and training methods for each mode, and the like.
FIG. 6 is a personal data input acceptance screen output to the monitor 70 by the training information processing unit 36e. This screen accepts input of basic personal data input from the input unit 50. The input basic personal data is transmitted to the in-store server 200 and written in a storage area (not shown) of the server 200.

FIG. 7 is an instruction screen that the training information processing unit 36e outputs to the monitor 70 when “abdominal muscle exercise” is selected as the training type. In the figure, “crunch” indicates the training type “abdominal muscle exercise”.
FIG. 8 is an instruction screen that the training information processing unit 36e outputs to the monitor 70 when “back muscle exercise” is selected as the training type. In the figure, “back extension” indicates a training type “back muscle exercise”.

FIG. 9 is an instruction screen that the training information processing unit 36e outputs to the monitor 70 when “right flank exercise” is selected as the training type. In the figure, “right side bend” indicates the training type “right flank exercise”.
FIG. 10 is an instruction screen that the training information processing unit 36e outputs to the monitor 70 when “left flank exercise” is selected as the training type. In the figure, “left side bend” indicates the training type “left flank exercise”.

(2-2-4) Load Control Unit The load control unit 36b determines a load curve based on the movable range of the bar 11 and the reference load, and the load that the torque motor 15 applies to the bar 11 based on the determined load curve. Adjust the value of. The movable range is determined by the movable range determination unit 36a, and the reference load is determined by the reference load determination unit 36c (details will be described later). For ease of explanation, the following example will be described by taking the case where the training type is abdominal muscle exercise as an example.

  FIG. 11 is a diagram for explaining the principle of the load curve determination method. Here, the load curve includes a linear change. The load control unit 36b determines a load curve according to the width of the trainee's range of motion. The load curve defines a load value according to the position of the movable range. The load value is equal to or greater than the reference load, and a range that does not exceed twice the reference load is preferable. The method of changing the load can be appropriately set depending on the training type and the configuration of the training apparatus 100.

FIG. 11A shows different ranges of motion Wa and Wb according to different trainees A and B. FIG. In this figure, the position when the bar 11 is at the highest point is the 90 ° position, and the position where the bar 11 is rotated 90 ° downward from the 90 ° position is the 0 ° position. The range of motion Wa of the trainee A is 80 ° to 20 °, and the range of motion Wb of the trainee B is 60 ° to 15 °.
FIG. 11B shows an example of an abdominal muscle exercise load curve corresponding to the movable ranges Wa and Wb. In this example, for ease of explanation, it is assumed that the reference load serving as a reference load when the trainees A and B perform training is the same value “M1”. According to this load curve, when the bar 11 moves from the start end to the end of the range of motion, the load value increases linearly from M1 to M1 ′, and when the bar 11 moves in the reverse direction, the load Decreases linearly from M1 ′ to M1. Since the trainee A and the trainee B have different widths of the movable ranges Wa and Wb, that is, the amplitude of the bar 11, the slopes of the load curves are different. Therefore, even if the bar 11 is at the same position, the load value based on the load curve for the trainee A is different from the load value based on the load curve for the trainer B. In this way, by determining the load curve according to the width of the range of motion that varies depending on the trainee and controlling the load applied to the bar 11, it is possible to optimize the exercise of each trainer and improve the exercise efficiency. it can.

The load M1 ′ at the end of the movable range is called a final load. The final load value M1 ′ is N times the reference load M1 ( 1 <N <2 ). At the end of the forward path of forward bending exercise, it is easy for the trainer to apply strength to the abdominal muscles, and training becomes easier, so by increasing the load by that amount, the training effect can be achieved throughout the repeated exercises. It can be maintained at approximately the same level, and trainers can perform effective training. The same applies to the left and right flank exercises.

  In the above example, the load changes linearly. In this case, if the reference load M1, the final load M1 ′, and the movable range (Wa, Wb) are determined, a linear change line is simply obtained. The control design can be made easy. In cases other than such a linear change, for example, when the load changes in a curved line, or even if it is a linear change, the change in which the load is maximized at the center of the movable range, such as barbell motion, Data stored in the pattern storage unit 36b-1 can be cited and supported (see other embodiment (A) described later).

  FIG. 12 is a load curve in consideration of the dynamic friction force f generated in the chain 13. For ease of explanation, a load curve in which the dynamic friction force f is added to the load curve of the trainee A in FIG. 11A will be described. In the figure, a load curve indicated by a one-dot chain line is a forward load curve, and a load curve indicated by a two-dot chain line is a return load curve. The forward load curve coincides with the load curve shown in FIG. The return load curve is determined to be higher by a fixed value 2f than the forward load at the same position. As shown in this figure, the load curve may be different between the forward path and the return path.

It is preferable to consider the dynamic friction force f for the following reason. In the forward path, a dynamic friction force f is generated in the chain 13 when the trainee tries to tilt the bar 11 forward. For this reason, the total load F1 experienced by the trainee is the sum of the load M1 applied to the bar 11 by the motor and the dynamic friction force f, that is, F1 = (M1 + f).
On the return path, the trainee returns the upper body to the start end side while lightly pushing back the bar 11 to return to the near side. This is because the torque motor 15 always applies a load in the direction in which the bar 11 is pushed up. At this time, the total load F2 experienced by the trainee is lighter than the load M2 applied to the bar 11 by the torque motor 15. Actually, the value is obtained by subtracting the dynamic friction force f from the load M2, that is, about F2 = (M2-f). Therefore, when the loads M1 and M2 applied to the bar 11 by the torque motor 15 have the same value (M1 = M2), the load on the return path is lighter than that on the forward path (F2 <F1). Therefore, the load M2 = (M1 + 2f) applied by the torque motor 15 on the return path is set. Thereby, the total load F2 = (M2−f) = ((M1 + 2f) −f) = (M1 + f) = F1 experienced by the trainee on the return path. Thereby, the trainee can experience a uniform load on the forward path and the return path, and an effective load can be applied to the trainee's muscles on the return path. Note that the difference in load between the forward path and the return path can be set as appropriate depending on the structure of the training apparatus 100.

FIG. 13 is a load curve that takes into account the effects of weight and posture on training. Appropriate stimulation can be applied to the target muscle by applying the load in consideration of the influence of the body weight in a posture where the weight can be a resistance to the load. For example, in the abdominal muscle exercise in the present training apparatus 100, the more the upper body is tilted, the more the weight of the upper body works as a resistance to the load (that is, it becomes easier for the trainee). The same applies to exercises on the left and right flank. Therefore, in order to cancel out the resistance to the load, the load may be further increased as the bar 11 is lowered to the end side. This increase in load is referred to as a weight offset load. The weight offset load can be expressed by the following equation. The formula for calculating the weight-cancelling load and its value can be set as appropriate according to the type of exercise, the training mode, and the structure of the training device 100. (Weight offset load) = (weight) × a × cos θ
Where 0 <a <1
θ: Angle indicating the position of the bar (when the horizontal position is the basic position, the angle of the bar with respect to the basic position)
The load curve indicated by the alternate long and short dash line in FIG. 13 is the same as the load curve of the trainees A and B shown in FIG. In FIG. 13, the alternate long and two short dashes line indicates the weight cancellation load. In order to simplify the explanation, the weights of the trainees A and B are the same, and a single weight offset load curve is shown. The load curve indicated by the solid line is a load curve indicating the sum of the basic load and the weight-canceling load defined by the load curve shown in FIG.

  FIG. 14 is an explanatory diagram illustrating examples of specific values of loads. The basic loads of the trainees A and B are associated with the angle indicating the position of the bar 11. In this example, the reference load M1 = 25.0 kg and the final load M1 ′ = 37.5 kg. The weight offset load changes in the range of 0 to 10.0 according to the angle. As a result of adding the weight offset load, for the trainee A, when the bar 11 moves in the range of 80 ° to 20 °, the load changes in the range of 26.7 to 46.9 Kg. For the trainee B, when the bar 11 moves in the range of 60 ° to 15 °, the load changes in the range of 30.0 to 47.2 Kg.

(2-2-5) Range of motion determination unit The range of motion determination unit 36a determines the range of the range of motion necessary for determining the load curve by measurement. The range of motion is determined for each trainer and for each training type.
For example, the range of motion determination unit 36a can measure the range of motion in the measurement mode (“muscle strength measurement mode” in FIG. 5) prior to the start of training. The measured range of motion is written in the personal data of the server 200, and is used to determine a load curve when performing training. When measuring the range of motion in the measurement mode, it is preferable to measure the range of motion by applying a small load of about 3.0 kg to 5.0 kg to the bar 11 and monitoring the position where the bar 11 reciprocates at least once. The movable range data indicating the movable range measured in this way is transmitted to the server 200 and written in the additional personal data. If the range of motion data has already been written for the same training type, the latest range of motion data is overwritten.

  Further, for example, the range of motion determination unit 36a may measure the range of motion when the range of motion data for the training type is not included in the personal data at the start of training. Specifically, after the start of the repetitive motion, the start point S and the end point E are determined from the average values of the second and third start points S2, S3 and end points E2, E3 of the first three reciprocations. Good. A range between the determined start point S and end point E is a movable range. The measured range of motion data is transmitted to the server 200 and written in personal data. In other words, if an attempt is made to start training but the range of motion data for the training is not in the personal data, the range of motion is measured at the beginning of the started training. There is an advantage that the trainee can execute training without measuring the range of motion in the measurement mode (such as the “muscle strength measurement” mode in FIG. 5).

  As described above, the movable range determination unit 36a can perform the measurement of the movable range according to the trainee at least once for one training type of one trainer. Therefore, the range of the range of motion reflecting the difference between the trainee's physique and the flexibility of the body can be acquired, and the load curve suitable for each trainee's physique and body can be determined. In the case of a training device in which the range of motion cannot be set and the bar 11 is reciprocated within a certain range determined from the beginning, for example, elderly people or the like cannot sufficiently bend forward, and the bar 11 is tilted forward. In some cases, it is not possible to complete a given training menu (for example, the number of round trips I have made is not counted). In this regard, according to the present embodiment, the training apparatus side determines the range in which the elderly person can move the bar 11, and then performs training using the range as a round trip. Can be performed. In addition, some trainees want to perform a wide range of reciprocating motions rather than a wide range of reciprocating motions. However, if the motion range is determined from the beginning, such a motion cannot be handled. If the training device uses weight, it is possible for the trainer to reciprocate in a narrow range at his / her own discretion, but in this case, setting for increasing the final load is not possible and the number of reciprocating motions I can not count. On the other hand, in the present embodiment, the movable range can be set intentionally even in the “muscle strength measurement mode” or other training modes. You can also count the number of reciprocations that you have done.

The method for determining the movable range is not limited to this example. It is desirable to use an appropriate method according to the structure of the training device and the training type.
(2-2-6) Reference Load Determination Unit The reference load determination unit 36c calculates a reference load necessary for determining a load curve from a value of 1RM. The reference load is a value obtained by multiplying the value of 1RM included in the personal data by a predetermined coefficient, for example, 0.8, and is determined empirically according to the structure of the training apparatus 100. Similar to the range of motion, the reference load is determined for each trainer and for each training type. The reference load determining unit 36c can determine 1RM necessary for obtaining the reference load by measurement or calculation as follows.

  For example, the reference load determination unit 36c measures 1RM in the measurement mode (“muscle strength measurement mode” in FIG. 5) prior to the start of training. The measured 1RM is written in the personal data of the server 200, and is used to determine a load curve when training is executed. When measuring 1RM in the measurement mode, the reference load determination unit 36c calculates the estimated 1RM based on the basic personal data of the trainee and a predetermined formula.

FIG. 15 is an explanatory diagram illustrating an example of an equation for obtaining the estimated 1RM. In this example, the estimated 1RM is obtained by the following equation.
(Estimated 1 RM) = (weight) × (1−body fat percentage / 100) × (coefficient A) × (coefficient B)
Here, the coefficient A differs depending on the training type and gender, and is obtained empirically. The coefficient B varies depending on the age and gender and is obtained empirically.

  Further, the reference load determination unit 36c measures how many times the trainee has reciprocated the bar 11 with the measurement load, and converts the measurement load into 1RM based on a predetermined conversion table (not shown). Here, the measurement load is set to, for example, 75% of estimated 1 RM. If the in-store server 200 has 1RM data acquired for the trainee in the past, the size of the 1RM, for example, 75% is set as the measurement load. In the predetermined conversion table, the number of reciprocating motions in the measurement load is associated with a coefficient for obtaining 1RM. For example, when 10 reciprocations have reached the limit with the measurement load, 1RM is obtained from 1RM = measurement load ÷ 0.75. Further, for example, when four reciprocations are the limit in the measurement load, 1RM is obtained from 1RM = measurement load ÷ 0.9. The obtained 1RM value is transmitted to the server 200 and written in the additional personal data. If a value of 1RM has already been written for the same training type, the latest value is overwritten.

  Further, for example, when 1RM in the training type is not included in the personal data at the start of training not via the measurement mode, the reference load determination unit 36c calculates the estimated 1RM, and multiplies the calculated value by a predetermined coefficient as a reference. It may be a load. In other words, when the training is started but the value of 1RM for the training is not included in the personal data, the estimated 1RM may be determined by calculation prior to the start of the training, and the reference load may be directly obtained therefrom. There is an advantage that training can be performed even if the trainee does not perform 1RM measurement in the measurement mode.

  As described above, the reference load determination unit 36c determines the reference load corresponding to the trainee from 1RM or estimated 1RM. Therefore, individual characteristics of the trainee can be reflected in the reference load. A load curve suitable for each trainer can be determined by obtaining a load curve based on the reference load thus obtained and the range of motion reflecting the trainee's physique.

The method for determining the reference load is not limited to this example. It is desirable to use an appropriate method according to the structure of the training device and the training type.
<Process flow>
Next, the process executed by the calculation unit 36 of the training apparatus 100 will be described with a specific example. For ease of explanation, a case where abdominal muscle exercise is selected as the training type will be taken as an example. The calculation unit 36 broadly executes (1) main routine, (2) seat position confirmation serve routine, (3) measurement processing subroutine, and (4) training processing subroutine.

(1) Main Routine FIG. 16 is a flowchart showing an example of the flow of the main routine executed by the calculation unit 36. In the main routine, acquisition of personal data, acceptance of selection of mode and training type, distribution of processing according to the mode, and the like are performed.
Step S1: When the training device 100 is activated, the calculation unit 36 starts a demonstration showing an outline of the training method.

Step S2: The calculation unit 36 waits for an input of the enter button or the quick start button while executing the demonstration. The enter button and the quick start button are provided in the input unit 50 (not shown).
Steps S3 to S6: The calculation unit 36 acquires personal data from the server 200 or receives input from a trainee. Specifically, when a user ID is input by the transponder during the demonstration (S3), the calculation unit 36 acquires personal data corresponding to the input user ID from the in-store server 200. If the basic personal data is not missing from the acquired personal data (S4), the process proceeds to step S7. When there is no input from the transponder (S3), the calculation unit 36 outputs a notification that the trainee cannot be authenticated, and inquires about the intention to continue the process (S5). If there is an intention to continue, a data input screen (see FIG. 6) is displayed, and input of basic personal data is accepted (S6). Further, even when the basic personal data acquired from the in-store server 200 is missing, the input of the basic personal data from the data input screen is accepted (S4, S6).

Steps S7 to S8: When the determination button is pressed during the demonstration (S7), the calculation unit 36 accepts selection of a mode and a training type (denoted as a part in the figure) from the trainee.
Steps S9 to S10: When the quick start button is pressed (S9), the calculation unit 36 sets “manual mode” and accepts selection of a training type (denoted as a part in the figure) from the trainee (S10). . Further, the calculation unit 36 may accept settings such as a target number of times and a target time.

Step S11: The calculation unit 36 executes a sheet position confirmation subroutine which will be described later. By this process, the seat position corresponding to the part of the training to be performed is determined.
Step S12: The calculation unit 36 determines whether or not the mode received in Step S8 is the measurement mode (shown as “muscle strength measurement” mode in FIG. 5). If so, the process proceeds to step S14.

Step S13: Since the measurement mode has been selected, the calculation unit 36 executes a measurement processing subroutine to be described later. In this process, the calculation unit 36 measures 1RM and a movable range, and transmits a measurement result to the server 200.
Step S14: The calculation unit 36 executes a training processing subroutine described later except in the measurement mode. In this process, the calculation unit 36 performs training according to the mode. Moreover, the calculating part 36 performs the measurement of a range of motion, and the calculation of estimated 1RM as needed.

(2) Sheet Position Confirmation Subroutine FIG. 17 is a flowchart showing an example of the processing flow of the sheet position confirmation subroutine executed by the calculation unit 36. When the process proceeds to step S11 in the main routine, the following process is started.
Steps S201 and S202: The calculation unit 36 determines whether or not the seat position needs to be changed based on the part of the training to be performed, that is, the training type (S201). When the change is necessary, the process proceeds to step S202, and a screen for instructing the change of the sheet position is output to the monitor 70. If no change is required, the process returns to the main routine.

Steps S203 and S204: The calculation unit 36 waits for the seat position, specifically, the seat direction to be changed (S203), and instructs the trainee to sit when the seat is rotated and set to the correct position. The screen to be output is output to the monitor 70 (S204). The change of the sheet position is determined by detecting the signal from the sensor 24 described above.
Step S205: The calculator 36 waits for the trainee to press the enter button (S205), and returns to the main routine.

With the above processing, the trainee can be seated on the seat at a position suitable for the mode and training type selected by the trainee.
(3) Measurement Processing Subroutine FIG. 18 is a flowchart showing an example of the processing flow of the measurement processing subroutine executed by the calculation unit 36. When the process proceeds to step S13 in the main routine, the following process is started.

Step S301: When the personal data acquired from the in-store server 200 includes past 1RM data of the trainee, the calculation unit 36 employs the 1RM data.
Step S302: When the personal data acquired from the in-store server 200 does not include the past 1RM data of the trainee, the calculation unit 36 is based on the basic personal data of the trainee and the predetermined formula described above. Then, an estimated 1RM is calculated.

Step S303: The calculation unit 36 multiplies the past 1RM data or the calculated estimated 1RM by a predetermined coefficient (0 <coefficient <1), and sets the load set to a smaller value as the measurement load. In the present embodiment, 0.75 is adopted as an example of the coefficient.
Step S304: Subsequently, the calculation unit 36 applies a small load, for example, a load of 3.0 kg to 5.0 kg to the torque motor 15, and measures the movable range. Then, for example, the position of the start end and the end when the bar 11 reciprocates once is detected and used as the movable range data.

Step S305: The calculation unit 36 applies a measurement load to the bar 11 by the torque motor 15, and measures the number of repetitions by the trainee. The number of iterations can be detected by acquiring the rotation direction and the number of rotations of the torque motor 15 from the motor signal processing unit 23.
Step S306: The computing unit 36 converts past 1RM data or estimated 1RM into 1RM based on the number of iterations measured in step S303 and a predetermined conversion table (not shown).

Step S307: The calculation unit 36 transmits the obtained 1RM value and movable range data to the server 200 together with the trainee ID. As a result, 1RM of the corresponding training type of personal data and the range of motion data are accumulated in the server 200.
The above-described processing is performed for the training type specified in step S8 of the main routine. Through the above processing, it is possible to measure the 1RM and the movable range in the designated training type and accumulate the measurement results as personal data.

(4) Training Process Subroutine FIG. 19 is a flowchart showing an example of the processing flow of the training process subroutine executed by the calculation unit 36. When the process proceeds to step S14 in the main routine, the following process is started.
Steps S401 to S402: When a mode other than the measurement mode is selected, the calculation unit 36 determines whether 1RM and movable range data are included in the personal data for the selected training type prior to execution of the training (S401). ). If it is determined that there is, the reference load is obtained from 1RM, and the final load is obtained from the reference load. Further, a load curve is determined based on the reference load, the final load, and the width of the movable range (S402). If it is determined that there is no 1RM and movable range data for the selected training type, the process proceeds to step S406, which will be described later.

  Step S403: The calculation unit 36 activates a training program of the selected training type. The training program is executed independently of the main routine and this subroutine. For example, if the “slow training” mode or “circuit training” is selected, a training program for controlling the output of the screen and sound is started according to the settings such as the training part selected by the trainee and the target number of times. If the “rhythm shape” mode is selected, a screen or audio output program is started in accordance with a previously stored pattern corresponding to the selected part. After the training process, the calculation unit 36 stores the training result in the in-store server 200. In the above training program, a virtual training character performs an exercise operation on the monitor 70 so as to guide an actual trainee as shown in FIGS. At this time, the movement position of the training character is also changed corresponding to the set range of motion. Specifically, in the case of a trainee who has little forward tilt in abdominal muscle exercise, for example, the range of motion is only 90 ° to 45 °, the training character of the monitor 70 is also only in front of 90 ° to 45 °. I try not to take a tilted posture. As a result, the actual exerciser can check the pace of the exercise and the movement range of the exercise while watching the movement of the training character.

  Steps S404 to S405: The calculation unit 36 starts load control according to the load curve determined in step S402. That is, the position of the bar 11 is detected, the load value corresponding to the detected position is read from the load curve, and the torque motor 15 is controlled so as to apply the read value load to the bar 11 (S404). This process is continued until the training program ends (S405), and upon completion, the display returns to the demonstration screen (S1).

Steps S406 to S407: When the calculation unit 36 determines that there is no 1RM and range of motion data for the training type selected in Step S401, it calculates an estimated 1RM (S406) and multiplies the calculated value by a predetermined coefficient. A reference load is set (S407).
Step S408: The calculation unit 36 activates a training program of the selected training type. Similar to step S403, the training program is executed independently of the main routine and this subroutine.

  Step S409: The calculation unit 36 monitors the position of the bar 11, and after the start of the repetitive motion, the average values of the second and third start points S2, S3 and end points E2, E3 of the first three reciprocations. From the above, the start point S and the end point E are determined. Further, the calculation unit 36 determines a range between the determined start point S and end point E as a movable range.

Step S410: The calculation unit 36 obtains the final load from the reference load calculated in step S406. Further, a load curve is determined based on the reference load, the final load, and the measured range of motion (S402).
Step S411: The calculation unit 36 regards the estimated 1RM as 1RM, and transmits the movable range data to the server 200. Thereby, the movable range data of the corresponding training type of the personal data is accumulated in the server 200. Thereafter, the calculation unit 36 controls the load until the training program ends based on the determined load curve (S404, S405).

  By the above processing, when the 1RM value and the range of motion data for the selected training type are in the personal data, a load curve based on the value is determined. If not, a reference load is obtained by calculation, a range of motion is measured, and a load curve is determined. Therefore, even if the 1RM and the range of motion are not necessarily measured in the measurement mode, it is possible to control the load suitable for the characteristics of the trainee. In particular, the magnitude of the change in load with respect to the change in the position of the bar 11 can be changed according to the width of the movable range reflecting the difference in the physique of the trainee.

"effect"
The training device according to the present invention applies a load to the bar 11 according to a load curve determined based on the reference load and the measured range of motion. Therefore, the magnitude of the change in the load with respect to the change in the position of the bar 11 can be changed according to the width of the movable range reflecting the difference in the physique of the trainee. Finding the reference load by measurement is preferable because it can realize not only the difference in the trainee's physique but also the change in load considering the difference in muscle strength. Furthermore, if the load curve is determined in consideration of the weight offset load, the influence of the trainer's weight and posture on the training can be mitigated, and a load with a value suitable for each individual trainer should be applied at a suitable timing. Can do.

<Other embodiments>
(A) The method of changing the load is preferably changed according to the training mode even for the training type or the same training apparatus. Thereby, in each kind of exercise | movement, a load can be changed effectively and an exercise effect can be improved. For example, in the barbell exercise, the center of the range of motion is a sticking point where it is difficult for the trainee to put effort. As the barbell (movable part) moves from the start end of the forward path to the middle so that the load increases at that part, the load gradually increases and the barbell moves from the middle toward the end of the forward path. It is better to gradually reduce the load. Specifically, a reference load is applied at the start end and the end, and load = reference load × 1.3 times in the middle. Efficient barbell movement can be achieved. Further, when the load curve is changed according to each training mode prepared in the same training device, data relating to the load curve set in the load pattern storage unit 36b-1 corresponding to each training mode, that is, What is necessary is just to memorize | store a load pattern and to determine a load curve based on the load pattern according to the selected mode. Examples of data stored as a load pattern include a calculation formula for a load curve itself, a calculation formula for a weight-canceling load, and the like.

  (B) The range of motion is preferably determined by measurement, but the present invention can be applied even when determined based on personal data. For example, personal data such as the height / age / gender of the trainee and standard range-of-motion data are associated with each other and tabulated in advance. The range of motion can be determined by reading the range of motion data from the table based on the personal data of the trainee and the table, and used for determining the load curve.

  (C) A program for executing the above-described method on a computer and a computer-readable recording medium recording the program are included in the present invention. Here, the program may be downloadable. Examples of the recording medium include a computer readable / writable flexible disk, hard disk, semiconductor memory, CD-ROM, DVD, magneto-optical disk (MO), and others.

  The present invention can be applied to a training apparatus for an individual to exercise with an exercise load optimum for the individual.
