Abstract

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 our laboratory, we have analyzed the cycling movement using the pedal sensor developed and the three dimensional motion analysis system(Vicon). In the previous study, the influence of the lower limb joint moment and the lower limb muscle myoelectric value(EMG value) on the change in saddle height was investigated for sports bikes and Japanese city-cycle. In this study, the authors investigated the influence on the lower limb joint moment, EMG value, EMG timing of lower extremeties during cycling motion on sports bicycle(road bike), mountain bike, Japanese city-cycle, recumbent cycle, which are different riding posture(different trunk angle).
