The purpose of this study was to determine the relationship between measures of unilateral and bilateral jumping performance and 10- and 25-m sprint performance. Fifteen division I women soccer players (height 165 ± 2.44 cm, mass 61.65 ± 7.7 kg, age 20.19 ± 0.91 years) volunteered to participate in this study. The subjects completed a 10- and 25-m sprint test. The following jump kinematic variables were measured using accelerometry: sprint time, step length, step frequency, jump height and distance, contact time, concentric contact time, and flight time (Inform Sport Training Systems, Victoria, BC, Canada). The following jumps were completed in random order: bilateral countermovement vertical jump, bilateral countermovement horizontal jump, bilateral 40-cm drop vertical jump, bilateral 40-cm drop horizontal jump, unilateral countermovement vertical jump (UCV), unilateral countermovement horizontal jump, unilateral 20-cm drop vertical jump (UDV), and unilateral 20-cm drop horizontal jump (UDH). The trial with the best jump height or distance, reactive strength (jump height or distance/total contact time), and flight time to concentric contact time ratio (FT/CCT) was recorded to analyze the relationship between jump kinematics and sprint performance. None of the bilateral jump kinematics significantly correlated with 10- and 25-m sprint time, step length, or step frequency. Right-leg jump height (r = -0.71, p = 0.006, SEE = 0.152 seconds), FT/CCT (r = -0.58, p = 0.04, SEE = 0.176 seconds), and combined right and left-leg jump height (r = -0.61) were significantly correlated with the 25-m sprint time during the UCV. Right-leg FT/CCT was also significantly related to 25-m step length (r = 0.68, p = 0.03, SEE = 0.06 m) during the UDV. The combined right and left leg jump distance to standing height ratio during the UDH significantly correlated (r = -0.58) with 10-m sprint time. In comparison to bilateral jumps, unilateral jumps produced a stronger relationship with sprint performance.
本研究旨在确定单侧和双侧跳跃表现与 10 米和 25 米冲刺表现之间的关系。15 名一级女子足球运动员（身高 165 ± 2.44cm，体重 61.65 ± 7.7kg，年龄 20.19 ± 0.91 岁）自愿参加本研究。受试者完成了 10 米和 25 米冲刺测试。使用加速度计测量以下跳跃运动学变量：冲刺时间、步长、步频、跳跃高度和距离、接触时间、向心接触时间和飞行时间（Inform Sport Training Systems，维多利亚，BC，加拿大）。以下跳跃以随机顺序完成：双侧反向垂直跳跃、双侧反向水平跳跃、双侧 40cm 垂直下落跳跃、双侧 40cm 水平下落跳跃、单侧反向垂直跳跃（UCV）、单侧反向水平跳跃、单侧 20cm 垂直下落跳跃（UDV）和单侧 20cm 垂直下落跳跃（UDH）。记录最佳跳跃高度或距离、反应强度（跳跃高度或距离/总接触时间）和飞行时间与向心接触时间比（FT/CCT）的试验，以分析跳跃运动学与冲刺表现之间的关系。双侧跳跃运动学与 10 米和 25 米冲刺时间、步长或步频均无显著相关性。右腿跳跃高度（r = -0.71，p = 0.006，SEE = 0.152 秒）、FT/CCT（r = -0.58，p = 0.04，SEE = 0.176 秒）和左右腿联合跳跃高度（r = -0.61）与 UCV 期间的 25 米冲刺时间显著相关。右腿 FT/CCT 也与 UDV 期间的 25 米步长显著相关（r = 0.68，p = 0.03，SEE = 0.06m）。UDH 期间双腿联合跳跃距离与站立高度比与 10 米冲刺时间显著相关（r = -0.58）。与双侧跳跃相比，单侧跳跃与冲刺表现的关系更强。
