  • Background and Study Aim: Volleyball is a sport with a high demand for explosive actions of the lower extremities, where vertical jump is a key determining factor. The aim of this study was to determine the effects of plyometric training on vertical jump in female players aged 12-18 years. Material and methods: A quasi-experimental, prospective, longitudinal design was used (n=32 intervention, n=12 control). Squat Jump, Counter Movement Jump, and Abalakov jumps were measured before and after 5 weeks of plyometric training using the MyJumpLab application. The intervention consisted of two weekly sessions of jumping exercises (e.g., pogo jump, depth jump, and unilateral jumps) with moderate-to-high intensity and progressive volume. Results: Significant improvements were showed in the intervention group for all three types of jumps (p < 0.001; Cohen’s d ranging from 0.82 to 1.14), with increases from 9.4% to 10.1%. The control group showed heterogeneous performance: it decreased in CMJ (-11.3%; p < 0.001; d = -1.51), remained stable in ABK (-0.4%; p = 0.956; d = -0.02), and improved in SJ (+13.4%; p < 0.001; d = 1.57). The comparison between groups showed significant differences in favor of the intervention group in CMJ (p < 0.001) and ABK (p = 0.002), but not in SJ (p = 0.263). Conclusions: Plyometric training positively influences vertical jump capacity. These findings support the implementation of plyometric training programs to optimize performance in young female volleyball players, which should be taken into consideration by coaches and practitioners of this sport.
