The influence of bicycle lean on maximal power output during sprint cycling

Competitive cyclists typically sprint out of the saddle and alternately lean their bikes from side to side, away downstroke pedal. Yet, there is no direct evidence as whether leaning bicycle or conversely, attempting minimize lean, affects maximal power output during cycling. Here, we modified a cycling ergometer so that it can but also be locked prevent lean. This made possible compare 1-s crank non-seated, under three different conditions: (no lean), ad libitum minimal We found did not enhance compared condition. However, trying decreased by an average 5% . IMU-derived measures provided subjects leaned pedal ad-lib condition, in overground finding suggests our provides suitable emulation bicycle-lean dynamics. Overall, find cycle does output, impairs output.
