EFFECT OF LATERALLY MOVEABLE PEDALS (BIUS) ON KINEMATICS, PEDAL FORCES AND MUSCLE ACTWIN IN RECREATIONAL CYCLING

Abstract

The purpose of this study was to investigate the effect of a laterally moveable pedal on the kinematics, kinetics and muscle activity in recreational cycling compared to cycling with a standard pedal on an ergometer. Four healthy participants cycled at 100 W and 200 W at 80 rpm with a standard and the BIUS pedal. Kinematics, kinetics and muscle activation have been measured in both conditions. No differences were found regarding the joint angles and in the lateral movement of the pedal. Some differences were partly observed for the ground reaction forces and the muscle activation pattern. In the ergometer setting the BIUS pedal does not lead to kinematic changes of the cycling movement, but causes effects on pedal forces and muscle activation.
