The purposes of this study were to set up of a bench simulator to simulate a flexural vibration of ski plate, and to investigate the relationship between the flexural vibration of a ski plate and human fatigue. To perform the first purpose, the flexural vibrations of the center of a ski plate in skiing and a grandeur in skiing and on tredmill were measured using accelerometers. It was found from the experimental result that the bench simulator using tredmill and the grandeur offered the simulation of flexural vibration of ski plate. To perform the second purpose, to investigate the relationship between the flexural vibration of a ski plate and human fatigue, the vibration simulating in skiing was loaded to a subject during 2 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, vibration frequency increased, MPF decreased. This results led to the conclusion that flexural vibration of ski plate cause muscle fatigue of skier.
