- Abstract
- Purpose: The purpose of this study is to find out the effect and chacrtaeristics of training according to the technical differences of drop jump by examining the effect of 6 weeks of depth jump & drop jump training on the isokinetic strength and agility performance.
Method: Nineteen collegiate Students participated in the present study and were randomly assigned to 6 weeks of depth jump (DEJ) or drop jump (DRJ) training twice a ewek. Data on the measured variables (isokinetic strength of knee flexion and extension, the height of avertical jump, and agility test) were collected before and after a 6-week training period. A 2×2 analysis varniace (two factors mixed-effects ANOVA) was used for the statical analyses. The significant level of hypothesis verification is set-up as α=.05.
Results: The results of this study are as follows. 1) The 6 weeks of edpth jump training significantly improved isokinetic strength & average power (60°/sec, 180°/sec, and 300°/sec speed condition), vertical jump performance, and agility (p<.05). 2). The 6-week drop jump training significantly improved agility (p<.05), but the isokinetic strength, average power, and vertical jump performance did not indicate significant improvement.
3) There were no significant differences between depth jmup (DEJ) & drop jump(DRJ) training on th e measured variables (isokinetic strength of knee flexion & extension, the height of vertical jump, and agility test) after 6 weeks of training (p<.05).
Conclusion: It is supported that depth jump (DEJ) and drop jump (DRJ) tirnaing is an optional and usefu l method that can be used to increase isokinetic strength, powe r,and agility in the final preparation phase o f athletes before the competition season.
