Abstract
The purpose of this study is to examine the effects of ankle plantar and dorsal flexion on the rating of perceived exertion (RPE) in pedaling. Seven healthy men performed two kinds of ankle movement pattern, which took neutral position (NP) and dorsal flexion position (DP) in the crank top dead center. Heart rate, Vo 2, joint movement, joint torque, joint power and crank torque were measured. The electric goniometer was attached to the ankle outside in order to feed back the ankle angle, and the practice was carried out. Two kinds of pedaling were carried out for every 4 minutes by turns succeeding 12 minutes warm-up exercise by incremental loading. Consequently, although NP and DP did not have the significant difference in HR and Vo 2, RPE in NP was significantly lower than in DP. Two factors were considered as a reason of the difference; (1) the hip extension torque at the down stroke was larger, (2) there were few work on lower extremities' in NP.
