Abstract (in Japanese) (See Japanese page) 
(in English) To evaluate the muscular activity in the ski jumping take-off motion of ski-jumping, the frewuency analysis of EMG with the wavelet transform has been applied to different athletes. The effectiveness of the proposed technique was confirmed in the measurement of EMG’s of a sprinter, a middle and a long distance runners. The analyzed results agreed well with their specialties. The frequency spectra of EMG’s were analyzed and compared between the athletes of special jumping and Nordic combined jumping. The results indicated that the athletes of special jumping used the fast twitch fibers effectively leading to the quick movement. Through this study, the applicability of the proposed technique to the objective evaluation of the take-off has been verified.
