Combined effect of plyometric training and weight training on muscular strength and cardiovascular endurance among university male athletes

This study was the find out the random group design. 80 male athletes (N=80) who represented their college in university level competitions were selected at random. The selected subjects were randomly divided into four groups and assigned into plyometric training group (Group-I), weight training group (Group-II) and combined training group (Group-III) and control group. Each group consisted of 20 subjects. The training period was 12 weeks and three sessions a week on alternative days. Prior to experimental treatments all the subjects were measured of the criterion variables selected for this study. After the completion of the experimental period, the all the subjects were again measured of the criterion variables selected. The differences between the initial and final means on criterion variables were considered as the effect of respective treatment among the subjects. To test statistical significance of the difference, the obtained data were analyzed using ANCOVA. In all cases 0.05 level.
