提出了5跳测试（5JT）来评价各项目运动员的下肢爆发力。虽然5JT的表现通常以绝对的形式表示，即所覆盖的总距离（即米），但受试者的大小在表现中起着重要作用。本研究的目的是测试5JT绝对性能与实验室爆炸威力测试的关系，并开发有助于提高5JT诊断价值的性能符号。对15名23岁以下突尼斯国家队优秀足球运动员进行5JT、力量平台垂直起跳（深蹲起跳[SJ]和手臂辅助反动作起跳[Arm-CMJ]）和同心圆等速腿伸/屈（90度）测试。S（-1）和240度。S (-1))5JT表现以绝对数字（米）、相对腿长（5JT-relative）和与体重相关的符号（body mass X 5JT, 5JT-body mass）表示。5JT性能与SJ高度和标度（W.kg(-0.67)）峰功率呈极显著相关（分别为0.72和0.77,p < 0.01）。5jt -相对值与SJ和Arm-CMJ高度（分别为0.61和0.71,p < 0.05）和缩放峰功率（分别为0.57和0.59,p < 0.05）显著相关。5jt -体质量与SJ （0.82, p < 0.0001）和Arm-CMJ峰值功率（0.54,p < 0.05）、SJ和Arm-CMJ峰值力（0.67,0.65,p < 0.05）显著相关。5JT-relative和5JT-body mass与膝关节伸肌240度显著相关。S (-1) （0.60, p < 0.05）和膝关节屈肌90度。S (-1) （0.67, p < 0.01）等速加速时间。本研究结果表明，5JT可作为精英足球运动员在野外条件下的爆发力诊断工具。使用考虑体型差异的表现符号可以提高5JT的诊断能力。
The 5-jump test (5JT) was proposed to evaluate lower limb explosive power of athletes competing in various disciplines. Although 5JT performance is usually expressed in absolute terms as the overall distance covered (i.e., in meters), subject size can play a significant role in the performance. The aims of the present study were to test the relationship of 5JT absolute performance with laboratory tests for explosive power and to develop performance notations useful to improve the diagnostic value of 5JT. Fifteen elite soccer players, members of the Under-23 Tunisian national team, were tested for 5JT, force platform vertical jumping ( squat jump [SJ] and arm-aided countermovement jump [Arm-CMJ]), and concentric isokinetic leg extension/flexion (90 degrees.s(-1) and 240 degrees.s(-1)). 5JT performance was expressed in absolute terms ( meters), relative to leg length (5JT-relative) and with body mass-dependent notations ( Body mass X 5JT, 5JT-body mass). 5JT performance was significantly correlated with SJ height and scaled (W.kg(-0.67)) peak power (0.72 and 0.77, respectively, p < 0.01). 5JT-relative values were significantly related to SJ and Arm-CMJ height (0.61 and 0.71, respectively, p < 0.05) and scaled peak power (0.57 and 0.59, respectively, p < 0.05). 5JT-body mass revealed significantly related of SJ (0.82, p < 0.0001) and Arm-CMJ peak power (0.54, p < 0.05) and to SJ and Arm-CMJ peak force (0.67 and 0.65, respectively p < 0.05). 5JT-relative and 5JT-body mass correlated significantly with knee extensors 240 degrees.s(-1) (0.60, p < 0.05) and knee flexors 90 degrees.s(-1) (0.67, p < 0.01) isokinetic acceleration time, respectively. The results of this study suggest that the 5JT may be regarded as an explosive strength diagnostic tool under field conditions in elite soccer players. The use of performance notation accounting for body size differences may improve the diagnostic ability of 5JT.
