Abstract

The aim of the present study is to evaluate the effect of an experimental pedal system (EP) on maximal isokinetic power generation and pedalling technique during cycling of well trained cyclists. Compared to habitual pedals (HP), in EP the foot contact area with respect to the pedal axis was located more inferior and anterior, which affects the distance between the crank axis and the point of force application (Functional crankarm length, Fcal) during the pedalling cycle. Since Martin (2001) showed enhanced propulsive torque in the downstroke of the pedalling cycle with longer crankarm length, we hypothesized EP to improve maximal isokinetic power output (P) and that the improvement is related to Fcal.
