スポーツ自転車のサドル高さが下肢関節モーメントと筋電に及ぼす効果

抄録

Bicycles have been widely used in Japan. However, especially for younger people, bicycles are used in a setting that does not match their body geometry or riding environment. In this study, first, the authors examined the effects of riding position on output power using a power meter attached to pedals with various cadences conditions. Next, the effect of saddle height on the joint moments of lower limb were evaluated by using three dimensional motion analysis system and six axis type pedal sensor. Moreover, evaluate the muscle operation timing and EMG values for various saddle height settings.
