Postactivation Potentiation Effects From Maximal Isometric Contractions Performed At Different Hip Joint Angles, Kyle Derosia
Masters Theses
The purpose of this study was to investigate the differences in vertical ground reaction force (VGRF) production and myoelectric activity after performing maximal isometric contractions at different hip joint angles. 10 healthy, experienced participants reported to the lab on two separate occasions where they performed 3 power cleans at baseline, then 4 maximal isometric deadlifts at either ~50° hip flexion angle (Max) or ~90° hip flexion angle (Min). Following the isometric deadlifts, another 3 power clean trials at 70% 1 repetition maximum were performed and used as a post-test. The isometric deadlifts served as the conditioning contraction (CC) to induce …
