In previous research, few studies have mentioned the influence of trunk muscles relates to a bicycle pedaling. In this study, we therefore intended to construct a measurement system for estimate the trunk muscle force using inverse dynamics calculations in bicycle pedaling. This system consist of measurement devices, (1) reacting force of the bicycle (pedal force, saddle force, handle force), (2) Pedaling action (pedaling posture, crank angle) and (3) Electromyogram (EMG) of right leg. As a result, these measured value obtained from the system were equivalent to previous research, and the data from this system can be used in the inverse dynamics problem.
