摘要: Objective To investigate how experience and feedback influence pacing performance during time trial cycling. Design Twenty-nine cyclists performed three 20 km cycling trials using a Computrainer. The first two (TT1 TT2) were (1) without any (n = 10), (2) with accurate 10) or (3) false showing the speed to be 5% greater than actual 9). All participants received full third (TT3), their data compared against TT2. Results Completion time, average power did not change among group, but strategy as indicated by lower cadence, 89.2 (SD 5.2) vs 96.4 (6.8) rpm, p Conclusions Pacing is influenced an interaction between previous experience. Conscious cognitive processes that lead ratings of perceived exertion appear
