The purpose of this study was to compare normalized peak power (PP) and peak barbell acceleration (BA) between the power clean (PC) and power hang clean (PHC) exercises among eight male weightlifters (25.5 ℗ł 2.86 yr; 85.25 ℗ł 11 kg). Biomechanical comparisons were made between both exercises at 60%, 70%, and 80% of each subject⁰́₉s one repetition maximum (1RM). When comparing both exercises for normalized PP, there was no significant difference at 60% and 70% of 1RM. At 80% 1RM, the PHC demonstrated significance (p = 0.016) with higher normalized PP when compared to the PC. When comparing both exercises for peak BA, results demonstrate greater BA for the PHC when compared to the PC at 60% (p = 0.036) and 70% (p = 0.041) of 1RM, but no significance at 80%. Results offer strength and conditioning coaches greater insight with regard to exercise selection and relative resistance when designing resistance-training programs for athletic populations.
