Effects of Passive Cycling Movement at Different Pedal Rotation Speeds on HR and Oxygen Pulse

[Purpose] The purpose of this study was to clarify the optimal pedal rotation speed of passive cycling movement (PCM). [Subjects] Twenty-one subjects (ten men and eleven women). [Methods] After sitting on a cycle ergometer for five minutes, PCM of the lower limb was performed for 5 minutes. Pedal rotation speed was randomly selected as 40, 60, or 80 rpm. [Results] Heart rate of PCM did not change from rest, but oxygen uptake and oxygen pulse significantly increased at each pedal rotation speed compared to rest. [Conclusion] These results suggest that the pedal rotation speed required in order to increase the oxygen pulse by PCM is 40 rpm or more.
