A comparison between two training programs and their effects on fatigue rates in women

This study investigated the effects of a plyometric training program and a traditional weight-training program on the onset rate of fatigue in the vertical jump in women. Twenty-five untrained college women ranging in age from 18-35 were randomly separated into 3 groups: a plyometric group, a traditional weight-training group, and a control (untrained) group. For the purpose of this study, the traditional weight-training group was defined as performing 3 sets of 10 repetitions at 70% of the subject's 1 repetition maximum (1RM). Training took place over a 10-week period for both the plyometric and traditional weight-trained groups. The plyometric group prolonged the onset of fatigue by 3.85 seconds as compared with their pretest data. The traditional weight-training group fatigued 0.55 seconds faster after training was implemented as compared with their pretest data. These results showed a significant difference between the groups in their onset rates of fatigue (p < 0.05). The results of this study show that a plyometric training program prolongs the onset rate of fatigue in the vertical jump in women as compared with a traditional weight-training program.
