HESPANHOL, Jefferson Eduardo; SILVA NETO, Leonardo Gonçalves; ARRUDA, Miguel de  and  DINI, César Augusto. Assessment of explosive strength-endurance in volleyball players through vertical jumping test. Rev Bras Med Esporte [online]. 2007, vol.13, n.3, pp.181-184. ISSN 1517-8692.

The aim of this study was to verify the differences between the continuous jump test of 60 seconds (CJ60 sec) and the intermittent jump test of 4 sets of 15 seconds (IJ4x15 sec). The sample was composed of 10 male volleyball players with 19.01 ± 1.36 years, 191.5 ± 5.36 cm height and 81.74 ± 7.45 of body mass, who participated in this research as volunteers. The variables studied were estimated as the peak power (PP), mean power (MP) and fatigue index (FI). These performances were measured through tests of vertical jump with duration the 60 seconds and with the performance of 4 sets of 15 seconds with 10 seconds of recovery between the sets. The data were analyzed through descriptive statistics and the Wilcoxon test. The significance level was of p < 0.05. It was possible to analyze that the continuous and the intermittent jump test presented significant differences in MP (p < 0.05), FI (p < 0.01), and in the number of the vertical jump in 60 seconds (p < 0.01), and the height in 60 seconds exercise (p < 0.05). The MP found in IJ4x15sec was significantly higher than in the CJ60 sec in volleyball players. In conclusion, the results suggest the existence of significant differences between the CJ60sec and IJ4x15 sec.
