Abstract

The purpose of this study was to determine and compare the optimal loads that would produce peak power output (PPO) in the hang clean and squat jump. Under-21 male rugby players (n = 59) from two rugby academies performed a maximal-strength test in the hang clean and squat, followed by a power test in the hang clean and squat jump with loads ranging from 30 to 90% of maximal strength (1RM). Pre-season and in-season testing was conducted. PPO for the hang clean was achieved at 90% 1RM during pre-season and at 80% 1RM during in-season. PPO forthe squat jump was achieved in a range from 60- 90% 1RM during pre-season and 50-90% 1RM during in-season. Optimal load for power production was 90% 1RM for the hang clean and 60-90% for the squat jump. Improvement in strength levels affected both peak-power production and the optimal load in both exercises. Results indicated that the more experienced the player was in strength training, the lower the percentage load that produced PPO. Load prescriptions would depend on the strength levels and training status of the players and should be monitored throughout the training year.
