The purposes of this study were to evaluate muscle fatigue by bench simulator to simulate a flexural vibration of ski plate, and the effect of using amino acid on muscle fatigue by bench simulator. To perform the first purpose, to investigate the evaluation of muscle fatigue, the vibration simulating in skiing was loaded to a subject during 10 minutes by the bench simulator using a treadmill and the grandeur. In this measurement, surface EMG was measured and the mean power frequency (MPF) was calculated. The result indicated, as vibration frequency increased, MPF decreased. To perform the second purpose, the effect of amino acid on muscle fatigue was investigated. A subject used amino acid, and the vibration simulating in skiing was loaded to a subject during 10 minutes by the bench simulator. From the experimental result it was not found that the effect of amino acid on muscle fatigue.
