Abstract

Provided is a control apparatus for an exercise therapy device to be used to carry out interval training where a high-intensity exercise and a low-intensity exercise, which have different exercise loads, are alternately carried out, including: an exercise load setting part for inputting an exercise load and exercise time period for the high-intensity exercise and low-intensity exercise from an input device of the exercise therapy device and setting the input exercise load and exercise time period in a storage part of the exercise therapy device as an exercise program; and a display control part for displaying a timing at which an exercise intensity of the exercise program is to change next during the interval training on a display device of the exercise therapy device.

Claims

1. An exercise therapy device, the exercise therapy device configured to be used by an exerciser to carry out interval training in which a high-intensity exercise corresponding to an anaerobic exercise and a low-intensity exercise corresponding to an aerobic exercise, which have different exercise loads, are alternately carried out, the exercise therapy device comprising:

a storage part in which an exercise program including set values of exercise loads and exercise time periods for the high-intensity exercise and the low-intensity exercise is stored;

a man-machine interface unit used by the exerciser and configured for selecting and setting the exercise program and displaying the exercise load proceeding along with a temporal change during the interval training;

a load control unit configured for controlling an exercise load to be applied to the exerciser according to the exercise program;

a load motor to be controlled by the load control unit to generate the exercise load;

a speed reduction mechanism for transmitting the exercise load generated by the load motor to the exerciser'"'"'s feet as an appropriate load torque and rotation speed; and

two pedals coupled to the speed reduction mechanism so as to be freely rotatable and used by the exerciser,

wherein the man-machine interface unit comprises;

a display control part configured for looking ahead to a time at which exercise intensity of the exercise program is to change next during the interval training in accordance with a descriptive content of the exercise program and displaying the exercise program graphically as the exercise load proceeding along with a temporal change on a display device of the exercise therapy device, the exercise program displayed graphically having a time axis as an abscissa axis including a past, present, and future time, and an exercise load axis as an ordinate axis, so that an exerciser is capable of carrying out training with the exercise load suited to a purpose while checking a next change of the exercise load, and displaying an exercise-finished portion that corresponds to a transition of the exercise load in the past time and a result of looking ahead that corresponds to a transition of the exercise load in the future time graphically using different lines.

2. The exercise therapy device according to claim 1, wherein the display control part displays the exercise program on the display device in a graph, and performs one of moving a marker indicating a current time on the displayed graph and scrolling the displayed graph so that a current time on the graph is displayed at the marker.

3. The exercise therapy device according to claim 1, wherein the display control part displays a period of time remaining until the exercise load is changed next on the display device.

4. The exercise therapy device according to claim 1, wherein when the interval training is finished, the display control part displays a ratio between a time ratio of the high-intensity exercise actually carried out by the exerciser and a time ratio of the high-intensity exercise on the exercise program on the display device as an achievement rate.

5. The exercise therapy device according to claim 1, wherein:

the pedals are operated by the exerciser to carry out the interval training; and

the display control part is configured to switch displaying between a temporal change of an average torque, which is an average value of rotation torques in one rotation of pedaling of the exerciser, and a temporal change of a peak torque, which is a maximum value of the rotation torques.

6. The exercise therapy device according to claim 5, wherein the display control part displays the peak torque on the display device during a period in which the interval training is the high-intensity exercise, and displays the average torque on the display device during a period in which the interval training is the low-intensity exercise.

7. A control method for an exercise therapy device executed by the man-machine interface unit in a control apparatus for the exercise therapy device according to claim 1, the control method comprising:

storing an exercise load and exercise time period for the high-intensity exercise and low-intensity exercise in a storage part of the exercise therapy device as an exercise program, input by the exerciser via an input device of the exercise therapy device; and

looking ahead to a time at which exercise intensity of the exercise program is to change next during the interval training in accordance with a descriptive content of the exercise program and displaying the exercise program graphically as the exercise load proceeding along with a temporal change on a display device of the exercise therapy device, the exercise program displayed graphically having a time axis as an abscissa axis including the past, present, and future time, and an exercise load axis as an ordinate axis, so that the exerciser is capable of carrying out training with the exercise load suited to a purpose while checking a next change of the exercise load, and displaying an exercise-finished portion corresponding to a transition of the exercise load in the past time and the result of looking ahead corresponding to a transition of the exercise load in the future time graphically using different lines.
