PROBLEM TO BE SOLVED: To obtain a training support system by which a subject can work on improvement of athletic ability with high motivation. The acceleration sensor can be mounted on a trunk of a subject, and when the left-right direction of the subject is the X-axis direction and the front-back direction of the trunk is the Z-axis direction, accelerations in the X-axis direction and the Z-axis direction are detected. Acceleration sensor 12, a control unit 2 that generates acceleration data in the X-axis direction and the Z-axis direction from the output signal of the acceleration sensor 12, and the acceleration data in the X-axis direction and the Z-axis direction are analyzed to determine the X-axis direction. An evaluation unit 31 that obtains the sum of the X-axis acceleration and the Z-axis acceleration at the timing when the acceleration becomes maximum and evaluates the exercise capacity of the subject by the maximum value of the sum of the accelerations obtained by a plurality of trials. ..
