Comparing the Effects of Plyometric Depth Jump and Rim Jump Training on the Explosive Power of Leg Muscle and the Level of Creatine Phosphokinase of Basketball Players

摘要

This experimental study was aimed at comparing plyometric depth jump and plyometric rim jump training on the explosive power of leg muscle and the level of Creatine Phosphokinase (CPK) of basketball players. 28 male basketball players were involved in this study and were randomly divided into two groups. Measurement on the explosive power of the leg muscles were carried out before and after training and the level of CPK was measured after 24 hours of the first training. And after having the training for 6 weeks, same measurements like the first ones were taken. From the results, it was discovered that the final measurement of group A showed a great increase in the explosive power of leg muscles (54.71 ± 5.40 vs. 60.50 ± 5.35), leg muscle strength (136.21 ± 152.71 ± 12.45 vs. 13.77), and levels of CPK (237.6 ± 146.1 vs. 329.4 ± 182.9). In group B, it was also discovered that there was an increase in the explosive power of leg muscles (54.86 ± 6.62 vs. 58.86 ± 6.33), and but a decrease in the level of CPK (356.3 ±214.2 vs. 226.4 ± 148.6). This study concludes that, plyometric depth jump training is more effective in increasing the explosive power of leg muscles and the level of CPK compared with plyometric rim jump training.
