The effect of aquatic plyometric training with and without resistance on selected physical fitness variables among volleyball players

The purpose of this study is to analyze the effect of aquatic plyometric training with and without the use of weights on selected physical fitness variables among volleyball players. To achieve the purpose of these study 36 physically active undergraduate volleyball players between 18 and 20 years of age volunteered as participants. The participants were randomly categorized into three groups of 12 each: a control group (CG), an aquatic Plyometric training with weight group (APTWG), and an aquatic Plyometric training without weight group (APTWOG). The subjects of the control group were not exposed to any training. Both experimental groups underwent their respective experimental treatment for 12 weeks, 3 days per week and a single session on each day. Speed, endurance, and explosive power were measured as the dependent variables for this study. 36 days of experimental treatment was conducted for all the groups and pre and post data was collected. The collected data were analyzed using an analysis of covariance (ANCOVA) and followed by a Scheff'é post hoc test. The results revealed significant differences between groups on all the selected dependent variables. This study demonstrated that aquatic plyometric training can be one effective means for improving speed, endurance, and explosive power in volley ball players.
