Abstract
In this study, we tested the hypothesis that, during the regular in-seasonal basketball training, an additional 7-week plyometric training program improves lower extremity strength, balance, agility, and jump performance in adolescent female basketball players. Eighteen female basketball players less than 17 years of age were randomly assigned into an experimental group (plyometric training) and a control group. Both groups underwent the same basketball training program. Pre- and post-training test periods included quadriceps and hamstring strength, balance, jump performance, and agility measurements. Illinois agility test time (p = 0.000) and quadriceps strength (p = 0.035) increased uniformly in the two groups. Significant group by test period interaction was found for countermovement jump (p = 0.007), and countermovement height reduced significantly in the plyometric training group (p = 0.012), while it remained unchanged in controls. No significant change was found for T agility test, balance, hamstring strength or H:Q ratio. This study shows that the training program used in-season did not improve the measured variables, except for knee extensor strength. It is possible that regular basketball trainings and games combined with high-volume plyometric training did not show positive functional effects because of the fatigue caused by incomplete recovery between sessions.
