Abstract
The purpose of this pilot study was to determine the functional roles of the lower extremity joints during a weightlifting exercise. One participant performed the power clean exercise with 75% of one-repetition maximum while 3D motion capture and force plate data were recorded. Net joint moments were calculated via inverse dynamics analysis and used as inputs to an induced acceleration analysis that calculated joint-specific contributions to ground reaction forces (GRF). Results showed that all joints exhibited to phase-specific contributions to vertical GRF. Interestingly, the ankle plantarflexors produced primarily anterior GRF, whereas the knee extensors produced primarily posterior GRF. The results underscore joint- and phase-specific contributions to the production of vertical and horizontal GRF during the power clean.
