Abstract/OtherAbstract:
PURPOSE: The main aim of this study was to compare the freely chosen cadence (FCC) and the cadence, at which the blood lactate concentration at constant power output is minimized ("optimal cadence", Copt). The second aim was to examine the effect of a concomitant change of road incline and body position on FCC, the maximal external power output (Pmax) and the corresponding Copt. METHODS: FCC, Copt, and Pmax were analyzed under two conditions: 1) cycling on level ground in a dropped position (LGDP) and 2) cycling uphill in an upright position (UHUP). Seven experienced cyclists participated in this study. They cycled on a treadmill to test the two main hypotheses: 1) Experienced cyclists choose an adequate cadence close to Copt independent of the cycling condition and 2) FCC and Copt are lower and Pmax is higher for UHUP compared to LGDP. RESULTS: Most but not all experienced cyclists chose an adequate cadence close to Copt. Independent of the cycling condition FCC and Copt were not statistically different. FCC (82.1 ± 11.1 rpm, and 89.3 ± 10.6 rpm, respectively) and Copt (81.5 ± 9.8 rpm and 87.7 ± 10.9 rpm, respectively) were significantly lower and Pmax was significantly higher (2.0 ± 2.1%) for UHUP compared to LGDP. CONCLUSION: Most experienced cyclists choose a cadence near Copt to minimize peripheral fatigue at a given power output independent of the cycling condition. Furthermore, it is advantageous to use a lower cadence and a more upright body position during uphill cycling.
