Abstract
Purpose: The purpose of this study is to determine the proper load as a percentage of the subject's 1 lift maximum or bodyweight to train for power on the plyo-press using the 3PQ system.
Methods: Sixty-seven college athletes were tested for maximal lower body strength (1 Lift Maximum (LM) plyo-press), and power output with various plyopress loads to determine if differences exist in power output between loads. The study consisted of a two week testing process, and during the two weeks the athletes participated in five different testing sessions. In session one body composition and maximal strength were recorded, in the four subsequent testing sessions the athletes performed plyo-press jumps at selected percentages of body mass (BM) (508M, 758M, 1 00BM, 1258M) or 1 LM (30LM, 50LM, and ?OLM). Power output was then analyzed using the 3PQ system.
Results: The Pmax occurred at a load of 50% of the subject's bodyweight (50%BM) for females with a peak power output of 41.8 ± 10.3 watts/kg. The Pmax for males occurred at a load of 75% of the subjects' bodyweight (75%BM) with a peak power output of 39.3 ± 9.2 watts/kg. The Pmax for 30%LM (35.7 ± 8.7 watts/kg) was not significantly different from 75%BM. Conclusion: The highest power output was achieved with a load of 50% of the subject's bodyweight for females. However, for men the optimal load was 30% of the subjects 1 LM and 75% of each subject's bodyweight. For strength training professional who are wishing to maximize their athlete's power outputs, the gender of the athlete needs to be considered.
