Predicting the volleyball spike jump height by the force-time curve variables of countermovement and volleyball spike jump

Popis výsledku v původním jazyce

Problem statement: Given the importance of achieving optimal performance in sports, monitoring, predicting, and enhancing sports performance is an important element for coaches and trainers. This study aimed to investigate the correlation between the force-time (F-T) curve variables of the concentric phase of the countermovement jump (CMJ) and the volleyball spike jump (VSJ) with the VSJ height in young female volleyball players. Material and Methods: Forty-two sub-elite young female volleyball players performed three VSJ and three CMJ in game-simulated circumstances on two 40cm×60cm Kistler force platforms (9290AD, Winterthur, Switzerland). Results: Pearson’s product-moment correlations showed no significant correlation between the height of the VSJ and the F-T curve variables (rmax = .25) of the CMJ. The results of the multiple regression analysis showed no significant contribution of F-T variables of the CMJ in the prediction of the VSJ height (p = .835). Peak Force (r = .46, p = .002), Relative Peak Force (r = .31, p = .049), Peak Power (r = .56, p < .001), Relative Peak Power (r = .50, p = .001), and RSImod (r = .39, p = .010) of the VSJ had significant correlation with VSJ height. Discussion: The findings of this study support the importance of selecting an appropriate sport-specific jump test for assessment, monitoring, and predicting jump performance. Conclusions: Specifically, to the results of this study, coaches and trainers may use the F-T curve variables of the CMJ to assess the explosive strength of the lower limbs, but not for the prediction of VSJ height. In addition, measures of peak force and peak power during the VSJ, whether absolute or relative, were found to contribute significantly to the VSJ height.
