The purpose of this study is to investigate the effects of the bike exercise by confirming the conductive response of the thigh muscles. In this study, two types of experiments, HPLT (high pedal rate low torque) and LPHT (low pedal rate high torque), were performed at almost equal work rates. both types of bicycle exercise were performed for a total of 25 minutes, with power varying every 5 minutes for each. This experiment was conducted on one subject (Age : 28 years old, Height : 173 cm, Skeletal muscle mass : 29.5kg) who has no history of musculoskeletal or neurological disease. We acquired the conductivity distribution images of the right thigh before experiment and after the bike exercise by using electrical impedance tomography (EIT). EIT measurement was conducted using sixteen electrodes which has placed on the right thigh at regular intervals. We divided thigh muscles into three muscle compartments T1, T2, and T3. And then, we confirmed how the conductivity changed in each muscle compartment. As a result, T1 showed the largest conductivity change and after that T2 and T3 followed. Also, at almost equal work rates, the increase in conductivity was greater for HPLT than for LPHT.
