Abstract
Volleyball conditioning during off season training focuses on developing core and leg strength. Due to its success in causing hypertrophy, weight training is the primary strategy for building the muscle in the legs. More recently, plyometric exercises have been implemented into the conditioning regimen of many sports. This study aimed to compare the effectiveness of a primarily plyometric schedule versus a primarily weightlifting schedule. It was hypothesized that the weight lifting-based conditioning would improve vertical jump height the most. For this study, a 30 to 70 percent ratio of weight lifting to plyometrics and vice versa was installed into the off season conditioning of a high school volleyball player. The participants´ standing jump and approaching jump was recorded. For the control, the preconditioning vertical jump height of each participant was taken. Group 1 (70% plyometric training) displayed the greatest improvement with an increased height of 3.0004 cm standing and 2.8702 cm approaching. There was only a 0.9144 cm increase in the standing and approaching jump height after training for Group 2 (70% weight lifting group). A dependent t-test (t(14) = -3.25, a=0.05 > p = 0.006) showed that there was a significant difference between the average vertical jump height before and after training for the standing jump of Group 1. Another dependent t-test (t(14) = -3.53, a = 0.05 > p = 0.003) revealed that there was also a significant difference between the average vertical jump height before and after training for the approaching jump of Group 1. The t-test (t(14) = -1.02 a = 0.05 > p = 0.351) used to analyze the difference in the means of the pre- and post- training of the average standing jump and approaching jump (t(14) = -0.95 a = 0.05 > p = 0.361) of Group 2 showed there was no significant difference. These results suggests that a primarily plyometric training regimen will improve a volleyball player’s vertical jump height more efficiently.
