【 摘 要 】

The purpose of this study is to evaluate the stability and reliability of the Session Rating of Perceived Exertion (sRPE) method compared to objective physiological measures of exercise intensity. Methods: Twelve moderately trained male and female college student performed an initial VO2max test to determine appropriate workloads for the training sessions. During the first week subjects performed steady-state exercise bouts on a cycle ergometer. The second week subjects performed steady-state at the same intensity but longer duration on a cycle ergometer. Heart rate, Rating of Perceived Exertion (RPE), sRPE and blood lactate (HLa) were recorded during all sessions. Results: There was no significant difference between the HLa of the 30-minute sessions 1 and 2. There were differences within the 60 minute sessions 4 and 8, but when there was adequate recovery there were no between day differences in the two sessions. Discussion: During exercise bouts of constant duration sRPE stays constant. sRPE is a reliable marker of internal training load and may reflect how hard one is working compared to objective markers indicating training intensity.
