Background and Objectives: The purpose of this investigation was to examine the potential effects of eight weeks volleyball specific plyometric training on lower limbs power, vertical jump and spike performances in university female volleyball players which are considered specific to volleyball success. Methods: Twenty university female volleyball players were randomly assigned to an intervention group (INT= 10) or an active control group (CONT= 10). INT completed an eight weeks specific plyometric training program with three sessions per week while CON continued their regular training. Training volume was similar between groups. Before (T0) and after (T1) the intervention, the two groups were evaluated for the squat jump (SJ) countermovement jump (CMJ) test, the spike jump test (SP), the five time-jump test (FJT) and Standing long jump test (SLJ). Results: For SJ, post-hoc tests revealed significant pre-to-post improvements for both groups [INT (p =0.001, ES=0.45, small); CONT (p =0.002, ES=0.51, small)]. For CMJ, post-hoc tests revealed a significant pre-to-post improvement for INT (p = 0.001, ES = 0.72, moderate), and a significant lower improvement for CONT (p = 0.016, ES = 0.63, moderate). For SP, post-hoc tests revealed a significant pre-to-post improvement for INT (p = 0.004, ES = 0.78, moderate), and a significant lower improvement for CONT (p = 0.011, ES = 0.67, moderate). For FJT, post-hoc tests revealed only a significant pre-to-post improvement for INT (p = 0.002, ES = 0.85, moderate). For SLJ, post-hoc tests revealed a significant pre-to-post improvement for INT (p = 0.001, ES = 0.74, moderate). Conclusions: Eight weeks specific plyometric training program had a positive impact on improving lower limbs power, vertical jump and spike performances in university female volleyball players.
