Abstract :
The purpose of this study was to find out the effect of isolated and combined resistance and plyometric training on explosive power of volleyball players. Sixty male volleyball players from Kanyakumari District, Tamilnadu, India were randomly selected as subjects for the purpose of the study. Their age ranged from 18 to 23 years. The selected subjects (N=60) were classified into four equal groups of fifteen each (n=15) at random. Group-I underwent resistance training, group-II underwent plyometric training, group-III underwent combined resistance and plyometric training, and group-IV acted as control. The selected dependent variable explosive power was assessed by vertical jump test. The subjects were tested on criterion variables before and after the completion of 12 weeks training programme. The data collected from the four groups prior to and post experimentation on selected dependent variables were statistically analyzed to find out the significant difference if any, by applying the analysis of covariance (ANCOVA). Since four groups were involved, whenever the obtained ‘F’ ratio value was found to be significant for adjusted post test means, the Scheffe’s test was applied as post hoc test to determine the paired mean differences, if any. Due to the effect of resistance training, plyometric training and combined resistance and plyometric training the selected power parameter vertical explosive power, have significantly improved. The results of the study also reveals that combined training is better than isolated plyometric and resistance training in improving vertical explosive power of the subjects.
