Despite a growing interest in handcycle sports, little is known about how to configure a recumbent handcycle to optimise performance. The aim of this study was therefore to examine the effect of different fore-aft positions in recumbent handcycling on mechanical efficiency and force application. Twelve able bodied participants were measured in four different fore-aft positions, which were configured to be at 94%, 97% 100% and 103% of the participant’s arm length. Kinematics, kinetics and oxygen consumptions were measured to 1) calculate the joint angles, 2) measure the distribution of force and work and 3) to determine the efficiency of each configuration. We found a significant increase in elbow extension and significantly more shoulder protraction in the larger fore-aft positions than in the shorter positions. Moreover, the participants demonstrated a more equal distribution of work and force in the closer fore-aft positions. However, the different configurations did not lead to a change in efficiency. The kinetic data thus suggest that a shorter fore-aft position is better, but since no significant changes were found for efficiency, and a relatively low power output was used, more research is needed to explore if a close fore-aft position is the most efficient under a racing load.
