Preliminary study : the effect of biomechanical foot orthotics in bilateral pedalling asymmetry in three cyclists affected by an anatomic asymmetry

International audienceThe optimization of the cyclist's position aims to increase performance and may prevent injuries. To find the optimum posture, taking into account anthropometry of the cyclist is essential [1] because an anatomic asymmetry (short leg) could alter the cyclist's balance causing a decrease of power output for one of the two lower limbs. Bilateral pedalling asymmetry may amplify the risk of premature fatigue and injuries [2]. Biomechanical foot orthotics (FO) are used to reduce injuries [3] and to increase performance [4] improving left/right balance between the two legs. The aim of this study was to analyse the effect of the installation of a new FO (just after the laying) on a bilateral pedalling asymmetry in cyclist affected by an anatomic asymmetry (short leg)
