And are arranged. Further, the seat portion 2 is provided with a triaxial acceleration sensor 41 (see FIG. 3) that detects accelerations in the triaxial directions of the longitudinal X axis, the lateral Y axis, and the vertical Z axis.

  As the drive unit, one that swings the seat 2 at least in the front-rear direction can be used, but when the front-rear direction is the X axis and the left-right direction is the Y-axis, not only the front-rear swing θy, It is preferable to be able to perform swinging in the left-right direction θx from the viewpoint of training of the balance function and exercise function of the body, and further, the movement in the front-rear direction X and the left-right direction Y, the movement in the vertical direction Z, and the vertical axis θz You may use what can also be made to move.

  FIG. 3 shows a schematic configuration of the exercise intensity sensing system according to the present invention. The three-axis acceleration sensor 41, and a low-pass filter circuit 42 that removes frequency components other than the operation of the oscillating motion device from the acceleration detection output of each axis (X-axis, Y-axis, Z-axis) of the three-axis acceleration sensor 41; The A / D conversion circuit 43 for A / D converting the acceleration detection output of each axis outputted through the low-pass filter circuit 42, the data processing, the arithmetic processing, the control processing, and the time management of the swing type exercise device Processing unit 45 formed by a microcomputer that is a computing means for controlling the display, display means such as a liquid crystal display for displaying various data such as results of computation processing and displaying a menu screen for input operation, and data An operation panel 22 having a switch for performing input and a memory 44 for storing calculation processing results and input data are provided.

  FIG. 4 shows the operation panel 22. Power switch S0, automatic and manual operation switches S1 to S5, operation speed adjustment switches S6 and S7, hip joint stretch switch S8, seat inclination adjustment switches S9 and S10, seat height adjustment switches S11 and S12, liquid crystal display A changeover switch S13, a personal body information setting switch S14, data input scroll switches S15, S16 and the like are arranged, and a liquid crystal display LCD0 is arranged in the center. In the figure, L0 to L13 are operation display lamps.

  The basic operation will be described with reference to the flowchart of FIG. 1. When the power switch S0 is turned on (ST1), the lamp L0 is lit and becomes operable. Then, the body weight is input using the personal body information setting switch S14 and the data input scroll switches S15 and S16 (ST2). FIG. 5 shows a liquid crystal display LCD0 display at this time.

  When the automatic or manual operation switches S1 to S5 are operated while the power switch S0 is turned on, the swing type exercise device starts the operation of swinging the seat 2 (ST3). The acceleration in each direction of the X-axis, Y-axis, and Z-axis of the seat 2 at this time is detected by the triaxial acceleration sensor 41, and this acceleration measurement output is a frequency other than the operation of the oscillating exercise device by the low-pass filter circuit 42. After the component is cut, it is A / D converted by the A / D conversion circuit 43 and input to the arithmetic processing unit 45.

  The arithmetic processing unit 45 samples and captures the acceleration detection output in each axis direction that has been A / D converted at a predetermined time interval (ST4), obtains the combined acceleration of the acceleration output of each captured axis, and further calculates the mean square Is derived (ST5).

  And exercise intensity (METs) is calculated | required based on the approximated curve of the maximum oxygen uptake shown in FIG. 6, and the square mean of the introduced synthetic acceleration.

At this time, in view of the fact that the exercise intensity changes depending on how the user swings the swing type exercise device, the level of how the arithmetic processing unit 45 gets on the basis of the change in the integrated power or drive current value of the drive unit 11 is determined. By determining and introducing a correction value based on the determination result, exercise intensity (METs) is calculated in consideration of how to ride (ST6).

Further, the arithmetic processing unit 45 obtains the calorie consumption from the previously input weight, the operating time of the swing type exercise device, and the exercise intensity (ST7). The formula is as follows.
Calorie consumption (kcal) = exercise intensity (METs) x body weight (kg) x time (h)
Then, after obtaining exercise intensity (METs) and calorie consumption, a process of temporarily storing them in the memory 44 in time series is performed (ST8). The stored exercise intensity (METs) and calorie consumption are displayed on the display unit LCD0 of the operation panel 22 in accordance with the switching operation by the display switching switch S13. In addition, each display is updated to the latest calculation result at regular time intervals.

  The determination result of how to ride the swing type exercise device is displayed as the level of riding by the display lamps L11 to L13 of the operation panel 22. For this reason, the user knows the current state of riding and learns how to use it on the spot.

  As shown in FIG. 7, a heart rate monitor 51 or a pulse meter 52 is connected to capture the heart rate or pulse during the user's exercise, and the heart rate or pulse value is displayed on the display LCD0 of the operation panel 22 as shown in FIG. May be displayed. Note that the output of the heart rate monitor 51 or the output of the pulse rate monitor 52 may be captured wirelessly instead of wired. J1 in FIG. 9 indicates a receiving unit for receiving the radio (including optical communication).

In addition, it is preferable to display not only the current heart rate (pulse rate) but also the processing shown in FIG. That is, the power switch S0 is turned on (ST10), the personal physical information setting switch S14 and the data input scroll switches S15 and S16 are used to input age / weight / resting metabolism (ST11), and the heart rate monitor 51 or pulse meter 52 is further input. Is put on the body (ST12) and then the swing motion is started (ST13), the measured heart rate (pulse rate) HR and the target heart rates HRa and HRb obtained by the following formulas A comparison is made, and the operation speed of the drive unit 11 of the swing type exercise device is changed based on the comparison result.
Target heart rate HRa = [(220−age) −resting heart rate] × a + resting heart rate target heart rate HRb = [(220−age) −resting heart rate] × b + resting heart rate a, Each b is a coefficient representing the exercise load.

  In the case of the illustrated example, when the measured heart rate (pulse rate) HR is larger than the target heart rate HRa, the operation speed of the drive unit 11 is controlled to be reduced (down) (ST15), with a certain time interval. After that, the target heart rate HRa and the measured value are compared again (ST14). When the measured heart rate HR is larger than the target heart rate HRa, this is repeated.

  If the measured heart rate HR is smaller than the target heart rate HRa, the operation shifts to comparison with the target heart rate HRb. Control is performed (up) (ST17), and after a predetermined time interval, the target heart rate HRb and the measured value are compared again (ST16). When the measured heart rate HR is smaller than the target heart rate HRb, this is repeated.

  When the measured heart rate HR is larger than the target heart rate HRb, the operation speed of the drive unit 11 is maintained as it is (ST18).

  In this case, the measured heart rate HR is controlled so as to maintain the relationship of HRa ≧ HR ≧ HRb between the target heart rates HRa and HRb. The target heart rate HRa, HRb is not derived from the above formula, but may be a value set by the user himself / herself.

  And the operation | movement (ST19, ST20) which calculates | requires exercise intensity | strength (METs) from the 3-axis acceleration sensor 41 mentioned above and calorie consumption, and the process (ST21) which preserve | saves temporarily in the memory 44 in time series are also performed. The stored exercise intensity (METs) and consumed calories are displayed on the display LCD0 of the operation panel 22 (ST22).

  On the operation panel 22, the display of the heart rate HR, exercise intensity (METs), and calorie consumption can be switched and displayed from the display changeover switch S <b> 13. In addition, each display is updated and displayed with the latest calculation result at regular time intervals.

  10 and 11 show a connection slot 23 for a storage medium (memory card) 24 arranged in the vicinity of the operation panel 22 for inputting data from the outside. When the storage medium 24 is inserted into the connection slot 23, the personal body information contained in the storage medium 24 is taken into the swing type exercise device, and based on the information, the arithmetic control unit 45 is effective and safe for the user. Control the swing motion so that you can move.

  If the exercise history / results are written in the storage medium 24 after use, the efficiency of exercise management can be improved.

  Although the storage medium 24 is used for data input from the outside, an external device connected by communication may be used.
