A comparison of the effects of depth jump training and squat jump training with weight on muscular performance development among male basketball players of Chulalongkorn University
Abstract:
The purpose of this research was to compare the effects of depth jump training and squat jump training with weight on muscular performance development among male basketball players of Chulalongkorn University. The subjects were 20 basketball players of Chulalongkorn University in academic year 2007 by purposive sampling. After three weeks of basic strength training, the subjects were randomly assigned into two groups, each group consisted of 10 basketball players: The first experimental group worked with depth jump training and the second experimental group did squat jump training with weight. Both groups trained two days a week for a period of six weeks. The data of leg muscular strength, leg muscular explosive power, speed and agility were taken before and after the experimental. The obtained data were analyzed in terms of means and standard deviations while t-test was also employed to determine the significant differences of the data before and after the experimental. After six weeks of experiment, the results indicated that: 1. Leg muscular strength, leg muscular explosive power, speed and agility in squat jump training with weight group were significantly better than before training at the .05 level and leg muscular explosive power in depth jump training group was significantly better than before training at the .05 level. 2. Leg muscular explosive power, speed and agility in squat jump training with weight group were significantly better than depth jump training group at the .05 level and leg muscular strength in both groups were not significant difference at the .05 level
