NAJERA LONGORIA, Raúl Josué et al. Analysis of repeated vertical jump in basketball players. Educ. fís. cienc. [online]. 2015, vol.17, n.2, pp.00-00. ISSN 2314-2561.

In order to analyze the effectiveness of explosive maximal strength related to repeated vertical jump (SVR by its abbreviations in Spanish) with short periods of passive recovery in basketball players, 12 athletes were evaluated in a protocol of four series (S) of 15-s jumps with 10-s recovery between S. Initial (ASI) and final jump height (ASF) were measured in each S. One-way ANOVA and Bonferroni post hoc analysis were used to identify ASF-ASI differences by S and a Student t test was used to analyze fatigue index between first and final S. The difference between ASF-ASI was progressively incremental from S1 to S4 (-2,8 ±6,2 cm, -6,8 ±4,9 cm, -8,4 ±5,6 cm y -9,3 ±5,9 cm, respectively), but only in S4 the difference was significantly higher than in S1 (p=0.014). It is possible that the recovery periods between each S influenced the maintenance of explosive muscular strength (FME by its acronym in Spanish) during the first 45-s of exercise, however, the sum of these executions led to an increased fatigue at the end of the test. FME may be affected by the amount of executions of SVR even with the inclusion of short recovery periods, between series. Work-recovery relationship is a factor to be considered in training of basketball players.
