ASYMMETRIC LOADING DURING THE HANG POWER CLEAN - THE EFFECT THAT SIDE DOMINANCE HAS ON BARBELL POWER SYMMETRY

Abstract

The vertical ground reaction force (GRF) of both feet and bar end kinematics were recorded using force platforms and high speed video simultaneously during hang power clean (HPC) performance with typical training intensities, in order to determine whether perceived handedness and ground kinetic asymmetry influenced bar end kinematics. There were significant differences between the GRF when side dominance was determined from GRF asymmetries (p≤0.05), but not when determined by perceived handedness. Similarly, there were significant differences between bar end power outputs when they were determined according to bar end asymmetries but not when determined by perceived handedness or GRF asymmetry. These results suggest mechanisms other than ground kinetic asymmetries influence bar end power output symmetry.
