Lower Limb Power in Young Volleyball Players

The aim of the study is to assess the level of specific lower limb power and reactive force in young volleyball players. The 15 female subjects were involved in three pre-tests: 15s jumps, 30s jumps and stiffness test performed according to the Bosco Protocol by using the Optojump Next System. After a 10-week plyometric training programme, a post-test was applied. Compared to the pre-test, the flight times, contact time, height jumps and power revealed significantly higher scores post-test for 15s and 30s jumps test. No significant differences were observed on any variables for the stiffness test. We conclude that the 10-week plyometric training programme increases the anaerobic power in terms of contact time, flight times, height jumps and power jumps. (C) 2015 The Authors.
