The purpose of this study was to compare the power production of the hang clean (HC), jump shrug (JS), and high pull (HP) when performed at different relative loads. Seventeen men with previous HC training experience, performed 3 repetitions each of the HC, JS, and HP at relative loads of 30%, 45%, 65%, and 80% of their 1 repetition maximum (1RM) HC on a force platform over 3 different testing sessions. Peak power output (PPO), force (PF), and velocity (PV) of the lifter plus bar system during each repetition were compared. The JS produced a greater PPO, PF, and PV than both the HC (p < 0.001) and HP (p < 0.001). The HP also produced a greater PPO (p < 0.01) and PV (p < 0.001) than the HC. PPO, PF, and PV occurred at 45%, 65%, and 30% 1RM respectively. PPO at 45% 1RM was greater than PPO at 65% (p = 0.043) and 80% 1RM (p = 0.004). PF at 30% was less than PF at 45% (p = 0.006), 65% (p < 0.001), and 80% 1RM (p = 0.003). PV at 30% and 45% was greater than PV at 65% (p < 0.001) and 80% 1RM (p < 0.001). PV at 65% 1RM was also greater than PV at 80% 1RM (p < 0.001). When designing resistance training programs, practitioners should consider implementing the JS and HP. To optimize PPO, loads of approximately 30% and 45% 1RM HC are recommended for the JS and HP, respectively.
