The purpose of this study was to examine the possibility of estimating the optimal load of the Hang Power Clean (HPC), Hang High Pull (HHP), and Mid-thigh Clean Pull (MTP) based on a relative percentage of the subjects’ body mass (BM). Fifteen males with experience in weightlifting (age: 21.8 ± 1.9 years; BM: 83.2 ± 9.0 kg; height: 175.4 ± 6.0 cm; 1-repetition maximum [1RM]: 93.0 ± 12.7 kg; 1RM to BM ratio: 1.12 ± 0.13) performed HPC, HHP, and MTP at intensities of 30, 40, 50, 60, 70, 80, and 90% BM. Kinematic data were collected through a 16-camera infrared motion capture system and processed based on a three-dimensional lower-extremity model. Kinetic data were collected from two force plates. Peak power was found at 80, 80, and 90% BM for HPC, HHP, and MTP, respectively. Highest peak power output was found during the HHP for all intensities when compared to HPC and MTP. Power production was higher in the MTP from 30-70% BM when compared to HPC, but at 80-90% BM this shifted toward HPC prevalence over MTP. Results of the present study indicate that relative percentages of body mass presented as a reliable alternative for prescribing loads for the HPC, HHP, and MTP for healthy males with experience in resistance training. This information is relevant for load prescription for exercises without the catch phase (HHP, MTP) in which trainers and coaches rely on 1RM tests in exercises with more technical complexity such as the power clean (PC) and HPC.
