<P>PROBLEM TO BE SOLVED: To provide a mechanism allowing those who carry out the training of the exercising form of sports to objectively perceive the degree of upgrade of the same. Ž<P>SOLUTION: An acoustic processing section 14 and a sound generating section 15 emits first to third guiding sounds showing the rhythm of the exercising form of a subject from a loudspeaker 16. An acceleration sensor 11 detects the acceleration while the subject does the exercise according to the guiding sounds. The sample of the accelerating is fed to an evaluation section 22 through signal processing by an ADC 17, a delay section 18, and a filter 20. The evaluation section 22 obtains the time interval between the time obtaining the sample in the specific point of the time waveform of the acceleration and the time obtaining the sample of the moment when shooting balls and shows the displacement amount between the time interval and the exemplified time interval shown by the ideal value parameter as the evaluation result.
