摘要: Relationship between unilateral jumping ability and asymmetry on multidirectional speed in team-sport athletes. J Strength Cond Res 28(12): 3557-3566, 2014-The influence of jump performance, between-leg asymmetries, has not been widely researched. This study analyzed how was related to jumping. Multidirectional measured by 20-m sprint (0-5, 0-10, 0-20-m intervals), left- right-leg turn 505, modified T-test performance. Unilateral vertical (VJ), standing broad (SBJ), lateral (LJ) Thirty male athletes (age = 22.60 ± 3.86 years; height 1.80 0.07 m; mass 79.03 12.26 kilograms) were recruited. Pearson's correlations (r) determined performance relationships; stepwise regression ascertained predictors (p ≤ 0.05). Subjects divided into lesser greater groups from each condition. A 1-way analysis variance found between-group differences Left-leg VJ correlated with the 0-10 intervals (r -0.437 -0.486). Right-leg all -0.380 -0.512). SBJ LJ tests -0.370 -0.729). except left-leg 505 -0.415 -0.650). predicted sprint. T-test. Regardless used form groups, no established. Horizontal speed. Athletes asymmetries similar this (VJ ∼10%; ∼3%; ∼5%) should experience detriments.
