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 unilateral jump performance, and between-leg asymmetries, on multidirectional speed has not been widely researched. This study analyzed how speed was related to unilateral jumping. Multidirectional speed was measured by 20-m sprint (0-5, 0-10, 0-20-m intervals), left- and right-leg turn 505, and modified T-test performance. Unilateral jump performance, and between-leg asymmetries, was measured by vertical (VJ), standing broad (SBJ), and lateral (LJ) jumping. Thirty male team-sport 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 speed and jump performance relationships; stepwise regression ascertained jump predictors of speed (p ≤ 0.05). Subjects were divided into lesser and greater asymmetry groups from each jump condition. A 1-way analysis of variance found between-group differences (p ≤ 0.05). Left-leg VJ correlated with the 0-10 and 0-20-m intervals (r = -0.437 to -0.486). Right-leg VJ correlated with all sprint intervals and the T-test (r = -0.380 to -0.512). Left-leg SBJ and LJ correlated with all tests (r = -0.370 to -0.729). Right-leg SBJ and LJ related to all except the left-leg turn 505 (r = -0.415 to -0.650). Left-leg SBJ predicted the 20-m sprint. Left-leg LJ predicted the 505 and T-test. Regardless of the asymmetry used to form groups, no differences in speed were established. Horizontal and LJ performance related to multidirectional speed. Athletes with asymmetries similar to this study (VJ = ∼10%; SBJ = ∼3%; LJ = ∼5%) should not experience speed detriments.
团队运动运动员单侧跳跃能力与多向速度不对称性之间的关系。《力量与体能研究杂志》28(12): 3557 - 3566, 2014年——单侧跳跃表现以及双腿间不对称性对多向速度的影响尚未得到广泛研究。本研究分析了速度与单侧跳跃之间的关系。多向速度通过20米短跑（0 - 5米、0 - 10米、0 - 20米区间）、左右腿505转身以及改良T检验表现来测量。单侧跳跃表现以及双腿间不对称性通过垂直跳跃（VJ）、立定跳远（SBJ）和侧向跳跃（LJ）来测量。招募了30名男性团队运动运动员（年龄 = 22.60 ± 3.86岁；身高 = 1.80 ± 0.07米；体重 = 79.03 ± 12.26千克）。皮尔逊相关性（r）确定速度与跳跃表现的关系；逐步回归确定速度的跳跃预测因素（p≤0.05）。根据每种跳跃条件将受试者分为较小和较大不对称性组。单向方差分析发现组间差异（p≤0.05）。左腿VJ与0 - 10米和0 - 20米区间相关（r = -0.437至 -0.486）。右腿VJ与所有短跑区间和T检验相关（r = -0.380至 -0.512）。左腿SBJ和LJ与所有测试相关（r = -0.370至 -0.729）。右腿SBJ和LJ与除左腿505转身外的所有测试相关（r = -0.415至 -0.650）。左腿SBJ预测20米短跑。左腿LJ预测505转身和T检验。无论用于分组的不对称性如何，均未发现速度差异。水平和LJ表现与多向速度相关。与本研究不对称性相似（VJ = ∼10%；SBJ = ∼3%；LJ = ∼5%）的运动员不应出现速度下降。
