dc.description.abstract The purpose of this study is to assess the effects of the Rotor (ROT), a new pedaling system that makes each pedal independent from the other so that cranks are no longer fixed at 180°, on endurance cycling performance. Following a randomized design, eight subjects (noncyclists; age (mean ± SEM): 22 - ± 1 yr; V̇O2max: 51.8 ± 1.0 mL·kg-1·min-1) performed two bicycle-ergometer tests on separate days, one with the conventional pedaling system (CON) and the other one with ROT. Starting at 75 W, the power output was increased by 25 W at 3-min intervals until volitional exhaustion. Gas exchange parameters and blood lactate were measured for every 3-min interval. At exercise intensities between 60 and 90% V̇O2max, delta efficiency (DE) was significantly higher in ROT than in CON (24.4 ± 1.9% vs 21. ± 1.1%, respectively). Although more research is needed, especially with trained riders, the Rotor system might improve delta efficiency during endurance cycling. Other performance determinants (V̇O2max, maximal power output) do not seem to be changed compared with the conventional system. spa
