Relation between maximal power in sprint cycling, pedal force orientation and strength of the lower limb muscles in elite sprint cyclists

Abstract

The aim of this study was to determine, in a high-level population, how the maximal power produced during pedalling relates to the capacity to orient the pedal force, and to the force-generating capacity of the six main muscle groups of the lower limb, and whether this relationship is improved by using specific velocity conditions during single-joint strength measurements. 19 high-level cyclists performed two separated sessions : first, maximal power during pedalling was assessed while strength capacities were assessed in different force-velocity conditions. Results  suggest that assessing single-joint strength at specific velocities is more relevant, and this, particularly in the extension phase. In the flexion phase, the power produced is largely influenced by the capacity to effectively orientate the force on the pedals.
