- Abstract
- Purpose – The main purpose of this study was to determine the effect of an 8-week jump training program, completed on either a hard or sand surface, on vertical jump performance in elite volleyball players. It was of major interest to determine if training on one surface yielded meaningful gains on the other surface. Further, this study sought to determine if the short term jump training program was effective for developing leg muscle function. Method – Eighteen elite national and state volleyball players were split into two groups and trained on either a hard surface (HS, n=10) or a sand surface (SS, n=8). The participants completed 1380 jumps during the 8-week training program progressing from 120-jumps/week to 240-jumps/week. Participants were assessed on both a hard and a sand surface, pre and post training, on volleyball performance tests the block jump (BJ), spike jump (SPJ), as well as leg muscle function via ground reaction force (GRF) data collected during countermovement jump (CMJ), squat jump (SJ) and drop jump (DJ) performance. Results – The HS group demonstrated significant gains in jump height for BJ on the hard surface (2.6%, p= 0.033) and sand surface (6.7%, p= 0.019) while the SS group only made significant gains in BJ on the sand surface (9.8%, p= 0.009). Neither group demonstrated significant (p<0.05) gains in SPJ performance. Strong correlations between pre intervention BJ and SPJ data suggested a level of consistency in the participants jumping ability regardless of the type of surface or skill (jump). GRF data demonstrated that leg muscle function predictors accounted for 86-89% of the variance associated with volleyball performance jump tests (BJ, SPJ). Conclusion – The 8-week jump training program did not greatly improve the overall vertical jump performance of elite volleyball players. It appears surface does impact performance directly but any gains made from training on either surface are not necessarily isolated to performance on the same surface being trained on. Interestingly, SPJ performance did not demonstrate a strong link to DJ variables, in fact, within this study it appears that the skill of performing a BJ and SPJ are closely related, both rely heavily upon concentric power and this is part of why such strong correlations were seen between the two jump types.; Masters of Human Movement
