Abstract
The purpose of this study was to evaluate the effect of 7-week plyometric training (PT) on dynamic balance (DB) and sports-related performance in basketball players. Twenty-eight high school basketball players were equally assigned into PT or control groups by S method (jumping height). All the players were underwent regular basketball practice, 5 times per week for 7 weeks, but the PT group underwent extra PT (180 ~ 228 jumps) 3 times per week during this period. The DB was evaluated by the 8-direction limits of stability (LOS) test. The sports performance was evaluated by the height of vertical jumping (Hv) and the time of T-test (Tt). A two-way mixed analysis of variance (ANOVA) was used to compare the different change between groups before and after training for each parameter. The study results indicated that PT group showed significant improvements not only in the Hv and Tt performance, but also in the performance of LOS overall, right, forward-left, backward-left directions than control group after training. It is concluded that 7 weeks PT can improve the DB and sports-related performance in high school basketball players. Therefore, it is strongly recommended to take PT in the pre-season conditioning program.
