Description

  The present invention relates to an exercise assisting device that expands and contracts a user's muscles without intentionally moving the body by giving a passive motion stimulus to the user.

  In recent years, exercise assistance devices (for example, refer to Patent Document 1) that automatically swing a boarding board on which a user rides, exercise assistance devices that automatically rotate a pedal on which a user puts both legs, and the like have been proposed. . This type of exercise assisting device gives the user passive movement stimulation, and the user can expand and contract muscles without consciously actively moving the body. Even with such other dynamic exercise stimuli, if the muscle stretches and contracts, glucose is taken into the muscle and glucose metabolism is increased, so that glucose is consumed, which is considered to contribute to the improvement of diabetes. That is, as a result of improvement of hyperglycemia and hyperinsulinemia, it can be said that it contributes to improvement of lifestyle-related diseases (diabetes, obesity, hyperlipidemia, etc.).

In order to efficiently perform glucose metabolism by muscle contraction, it is desirable to cause muscle contraction in muscles with large volumes (especially red muscles (slow muscles) that contribute to aerobic exercise). It is considered effective to contract muscles. As an exercise assisting device that promotes muscle contraction of thigh muscles, there is a configuration in which a support base that supports a user's buttocks in a state where the user is wearing a foot is provided and the support base is tilted ( For example, see Patent Document 2).

(Embodiment 1)
FIG. 1 shows the overall configuration of this embodiment. There is a pedestal 1 installed on an installation surface such as a floor, and a support base 2 on which a user M places a buttock and a pair of footrests 3 on which the user M places a foot F (see FIG. 2). Provided on the gantry 1. The upper surface of the footrest 3 is inclined downward from the heel side toward the toe side. The support base 2 includes a columnar columnar body 21 erected on the gantry 1, a casing 22 that houses the drive mechanism section 4, and a seat section 23 that is disposed on the casing 22 and on which the user M places a buttocks. Become. The seat portion 23 is connected to the drive mechanism portion 4, and the seat portion 23 is moved by the drive mechanism portion 4 to change the tilt angle with time. Each of the left and right footrests 3 is supported by the gantry 1 using a pantograph-like mechanism that expands and contracts in the vertical direction and a spring, and can be displaced in the vertical direction with respect to the gantry 1.

  When using the exercise assisting apparatus of the present embodiment, the user M places his / her feet on the footrest 3 so that the soles of bare feet are in close contact with the upper surface of the footrest 3, and places the buttocks on the seat 23. The drive mechanism unit 4 changes the magnitude of the load acting on the leg by the weight of the user M by changing the inclination angle of the upper surface of the seat 23 with respect to the upper surface of the gantry 1. Now, the load acting on the seat 23 when the upper surface of the seat 23 is substantially parallel to the upper surface (horizontal plane) of the gantry 1 is G11, the load acting on the footrest 3 is G12, and the gantry 1 If the load acting on the seat portion 23 when the upper surface of the seat portion 23 is inclined with respect to the upper surface is G21 and the load acting on the footrest 3 is G22, then G11 / G12> G21 / G22. In short, as the seat portion 23 is tilted, the user M approaches a standing state, and the load acting on the leg portion by the weight of the user M increases accordingly. Thus, the load acting on the leg (especially the thigh) of the user M changes according to the inclination angle of the seat 23.

  Although the specific structure of the drive mechanism unit 4 is not shown here, one or two motors as a drive source are provided, and the seat 23 is located between the position parallel to the gantry 1 and the position inclined with respect to the gantry 1. And a gear mechanism and a crank mechanism so as to incline within a plane including the column body 21 and each one of the footrests 3. Of course, other appropriate mechanical elements such as links and cams may be combined. Moreover, the inclination direction to the leg on one side substantially coincides with the bending / extending direction of the knee. Thereby, even a person with pain in a knee joint can use it. When the angle of the upper surface of the seat 23 with respect to the gantry 1 changes, the load acting on the leg of the user M increases and decreases, and consequently the load acting on the footrest 3 also increases and decreases, so the footrest 3 is displaced in the vertical direction. To do. At this time, since the relative distance between the position of the buttocks of the user M placed on the seat 23 and the position of the sole placed on the footrest 23 is kept substantially constant, the bending angle of the knee joint hardly changes. That is, even if the user M has pain in the knee joint as an isometric muscle contraction state, the occurrence of pain in the knee joint can be suppressed. Note that a drive source may be used for raising and lowering the footrest 3. The control of the drive source is performed by a control unit 10 mainly composed of a microcomputer via a drive circuit 12. The drive circuit 12 is an interface between the control unit 10 and the drive mechanism unit 4, and receives power from the control unit 10 and supplies power to the drive source of the drive mechanism unit 4. The configuration of the control unit 10 will be described later.

  The reason why the seat portion 23 is configured to be tilted in a plane including the column body 21 and each one of the footrests 3 is to prevent the lateral force from acting on the knee joint, Even a user M who has pains can be used. Moreover, since the load due to the weight of the user M acts on each leg, it is possible to apply a larger load than when the loads are applied to both legs simultaneously. In addition, when the knee joint is painful, it is known that the pain increases when the bending angle from the extended position of the knee joint is increased to a predetermined angle (for example, 40 degrees) or more. The angle is limited so that the bending angle of the knee joint is kept below a predetermined angle. In order to set the knee joint bending angle to a predetermined angle, the initial position of the seat 23 (that is, the height position of the seat 23) and the position of the footrest 3 with respect to the gantry 1 can be adjusted.

  A gasket spring can be used to adjust the height position of the seat portion 23. In addition, the structure of the support body 21 is similar to the structure in which the saddle of the automobile is raised and lowered, and a structure in which two cylinders are connected in a nested manner is used, and a split groove is formed in the cylinder opening of the outer cylinder. The width of the split groove is adjustable with a lever. Or it is good also as an electrically driven structure which raises / lowers the seat part 23 with a motor. Furthermore, a configuration may be adopted in which the seat portion 23 is detachably attached to the drive mechanism portion 4 and the seat portions 23 having various heights are connected in a replaceable manner.

  In the gantry 1, a pole 5 a is erected at a portion between the two footrests 3, and a handle 5 b protruding from the pole 5 a to the left and right is provided at the upper end of the pole 5 a. That is, the pole 5a and the handle 5b form a T shape. A grip portion 5 that can be gripped by the user's hand is provided at both ends in the longitudinal direction of the handle 5b, and a touch panel type input portion 6 is attached to an intermediate portion in the longitudinal direction of the handle 5b. Therefore, the input unit 6 has not only a data input function but also a display function. The grip portion 5 can be gripped by the user M as needed during operation of the exercise assisting device, but is usually used without gripping the grip portion 5.

  As shown in FIG. 2, each footrest 3 is provided with a pair of electrodes 8a and 8b, and each grip 5 is provided with a pair of electrodes 8c and 8d as shown in FIG. These electrodes 8a to 8d are provided for supplying a weak high-frequency current to the user M and measuring the impedance of the living body. That is, the electrodes 8a and 8c are provided for supplying a high-frequency current, and the electrodes 8b and 8d are provided for detecting a voltage. Hereinafter, the electrodes 8a and 8c are referred to as signal electrodes and the electrodes 8b and 8d are referred to as measurement electrodes.

  The biological impedance is obtained in order to obtain the body fat percentage of the user M, and this technique is known as a biological impedance method. That is, the amount of fat is estimated using the fact that the fat in the body has a lower water content than other parts, and the impedance increases as the amount of fat in the body increases. Specifically, a high-frequency current is passed between appropriate two appropriate signal electrodes 8a and 8b, and a potential difference between the two measurement electrodes 8b and 8d adjacent to the signal electrodes 8a and 8c is detected. Thus, the impedance of the living body is detected.

  Therefore, the signal electrodes 8a and 8c and the measurement electrodes 8b and 8d are connected to the estimation unit 11, and the estimation unit 11 supplies a high-frequency current that is a constant current to the appropriate signal electrodes 8a and 8c, and the measurement electrodes 8b and 8c The impedance of the living body is estimated based on the voltage detected in 8d. When there are a plurality of combinations of the signal electrodes 8a and 8c and the measurement electrodes 8b and 8d, the frequency of the high-frequency current is made different in order to identify which electrode the impedance is measured.

  For example, if the impedance between both hands, the impedance between both feet, and the impedance between the limbs are obtained, the impedance of the trunk can be obtained by subtracting the impedance between both hands and both feet from the impedance between the limbs. Since the impedance has a correlation with the amount of fat, the estimation unit 11 estimates the amount of body fat of the trunk from the obtained impedance.

  Further, if the amount of body fat in the body weight is small, it can be estimated that the muscle mass is large. That is, muscle mass can be estimated using body fat mass and body weight measured between limbs as parameters. Except for specific athletes, the muscle mass of the legs is considered to have a correlation with the estimated muscle mass. Therefore, if the muscle mass is estimated by the above method, the muscle mass of the leg is estimated. Here, in order to estimate fat mass and muscle mass in the estimation unit 11, not only impedance but also at least body weight as height, weight, sex, and age is required as a physical feature quantity. Enter physical features. Since the input unit 6 has a data display function as described above, the estimated fat mass and muscle mass may be displayed on the input unit 6. Here, if the weight and height are given as the physical feature amount, the estimation accuracy of the fat amount becomes high, but the fat amount can be estimated even if only the weight is known.

  When the fat amount and muscle mass of the user M estimated by the estimation unit 11 as described above are given to the control unit 10, the control unit 10 can perform appropriate exercise according to the fat mass and muscle mass. The drive mechanism unit 4 is controlled. In the control unit 10, the drive mechanism unit 4 is operated so that the amount of exercise is almost equal regardless of the user M, or the drive mechanism unit 4 is operated so as to increase the amount of exercise as the fat amount of the user M increases. Since the momentum is the product of the operating time for operating the support base 2 and the operating speed for operating the support base 2, the momentum increases as the operating time increases and the operating speed increases.

  Here, the exercise amount of the user M is obtained as, for example, glucose consumption or energy metabolism. That is, since the posture of the user M during exercise is almost determined, the load acting on the leg can be estimated based on the operation speed of the seat 23 and the weight of the user M. Since the muscle mass of the leg is obtained by the estimating unit 11 as described above, the consumption of glucose per unit time can be obtained using the load acting on the leg and the muscle mass. Actually, in the energy metabolism calculation unit 10 a provided in the control unit 10, the seat 23 is obtained using the target energy metabolism per unit time, the muscle mass obtained by the estimation unit 11, and the weight of the user M. Determine the operating speed. By instructing the drive control unit 4 of this operation speed, the seat portion 23 can be driven so as to obtain a target energy metabolism per unit time.

  In the present embodiment, the control unit 10 controls the drive mechanism unit 4 according to the fat mass and the muscle mass estimated by the estimation unit 11, but the drive mechanism unit 4 uses only one of the fat mass and the muscle mass. It is also possible to control. Further, as a simple configuration, a configuration in which the drive mechanism unit 4 is controlled without being interlocked with the fat mass or the muscle mass estimated by the estimation unit 11 may be used. If not interlocked, the configuration of the control unit 10 is simplified. In this case, the user M may set the amount of exercise by looking at the estimated values of fat mass and muscle mass displayed on the input unit 6.

(Embodiment 2)
In the first embodiment, the configuration in which the height and the weight are input from the input unit 6 is adopted. However, the user M does not always store the height and the weight correctly, and may input an incorrect value. . Therefore, in the present embodiment, an example in which a function for automatically measuring the height and weight of the user M is added, and data input of the height and weight from the input unit 6 is unnecessary is shown.

  First, a technique for measuring body weight will be described. In this embodiment, in order to measure the weight of the user M, the load sensor 7a (refer FIG. 4) is provided in both the footrests 3. As the load sensor 7a, a load cell including a piezoelectric element or a sensor that detects a tension amount of a spring with a differential transformer is used.

  Therefore, when the user M stands on the footrest 3 before sitting on the seat 23, the load acting on the footrest 3 can be measured by the load sensor 7a provided on the footrest 3, and both load sensors can be measured. The added value of the load measured in 7a can be used as the weight of the user M. The addition of the measurement value of the load sensor 7a is performed by the weight estimation unit 11a provided in the estimation unit 11. Needless to say, the grip portion 5 is not gripped when measuring the weight.

  However, it may be a burden for the user M who has pain in the knee to place the grip 5 on the footrest 3 without gripping the grip 5. Therefore, a configuration in which the load sensor 7a is provided in the seat portion 23 in addition to the footrest 3 may be employed. In this configuration, the weight of the user M is supported at three points by placing the foot on the footrest 3 and sitting on the seat portion 23 in the same way as during exercise when measuring the weight. If the user sits on the seat 23, the burden on the knee of the user M is reduced without gripping the grip 5, so that the weight of the user M acts on the footrest 3 and the seat 23. If the measurement values obtained by the individual load sensors 7a are added, the weight of the user M can be measured.

  On the other hand, the height of the user M is estimated by making the bending angle of the knee joint of the user M a predetermined angle during exercise. As described in the first embodiment, the height position of the seat portion 23 can be adjusted in order to keep the bending angle of the knee joint of the user M at a predetermined angle. Further, the height position of the seat portion 23 is detected by the length sensor 7b. The position where the foot is placed on the footrest 3 is defined by an appropriate mark or the like. Therefore, if the height position of the seat part 23 is adjusted and the bending angle of the knee joint is set to a predetermined angle (for example, 40 degrees), the user can use the height position of the seat part 23 detected by the length sensor 7b. The leg length of M can be obtained. This calculation is performed by the height estimation unit 11 b provided in the estimation unit 11. Here, although the exact height cannot be estimated from the leg length, the height is obtained because the muscle mass of the leg is estimated, so the object can be achieved by the leg length instead of the height.

  Since the height (leg length) can be automatically estimated by adjusting the device as well as the weight, there is no need to separately measure the height and leg length, as in the case of inputting the height from the input unit 6. The possibility of erroneous input can be prevented. Other configurations and functions are the same as those of the first embodiment.

(Embodiment 3)
In each of the embodiments described above, weight, height, sex, and age are input from the input unit 6 to estimate muscle mass. However, if another biological profile is input from the input unit 6 for the user M, The momentum can be determined more appropriately. The configuration shown in FIG. 5 is obtained by adding a function for generating an exercise menu suitable for the user M in the configuration of the second embodiment. However, the function of generating an exercise menu may be added to the configuration of the first embodiment.

  For example, assuming that the presence / absence and type of disease, physical condition such as blood pressure, exercise history, and the like are input as a biometric profile, the magnitude of the load (that is, the operation speed) can be adjusted with the same amount of exercise. . For example, for a user M with high blood pressure, an exercise menu is created so that the desired load (exercise amount) can be achieved by reducing the load and extending the exercise time, and this exercise menu is driven. The control unit 4 is instructed. A standard exercise menu is stored in the menu storage unit 9a for each type of biometric profile, and when the user M inputs a biometric profile, an exercise menu corresponding to a similar biometric profile is stored from the menu storage unit 9a. Extract and use. Here, when an attribute such as blood pressure in the biometric profile is input from the input unit 6, classification is performed such as low blood pressure, normal blood pressure, and high blood pressure, and then collation is performed with the menu storage unit 9 a.

  By increasing the amount of information regarding the biometric profile of the user M input from the input unit 6 as described above, an exercise menu suitable for the user M can be set in detail, and the operation speed corresponding to the user M can be set. And the operation time can be set.

  By the way, the history storage unit 9b may be provided separately from the menu storage unit 9a, and the history of changes in fat mass and muscle mass for each user M may be stored. That is, since fat mass and muscle mass are estimated for each exercise, the estimated fat mass and muscle mass are stored in the history storage unit 9b together with the date and time (clocked by a clock unit not shown). From the history stored in the history storage unit 9b, the exercise effect is evaluated by the evaluation unit 13 every appropriate period such as one month. For example, the evaluation unit 13 obtains the difference in fat mass between the start point and the end point of the period, and corrects the exercise menu so as to increase the amount of exercise for one time when the difference in fat mass is smaller than a specified target value. Since the momentum is the product of the movement speed and the movement time of the seat 23 as described above, when the momentum is determined to be insufficient by the evaluation by the evaluation section 13, the control section 10 determines the movement speed or movement. An instruction is given to the drive control unit 4 to increase the time. Although the target value is set for the fat mass here, it may be set for the muscle mass or for both the fat mass and the muscle mass.

  The history of changes in fat mass and muscle mass stored in the history storage unit 9b can be called up and displayed on the input unit 6. By showing the change in fat mass and muscle mass to the user M, it is possible to motivate exercise. The menu storage unit 9a and the history storage unit 9b can be realized by a single storage device. Other configurations and operations are the same as those of the above-described embodiment.

  In addition, in each embodiment mentioned above, although the structure which supports the user's M buttocks was illustrated, the technical thought of this invention is applicable if it is a structure which can support not only a buttocks but a part of the user's M body. Thus, for example, a configuration in which the user M is suspended from above by a harness can be employed.
