Explosive actions are integral to soccer performance and highly influenced by the ability to generate maximal power. The purpose of this study was to investigate the relationship between force-velocity profile, jump performance, acceleration and maximal sprint speed in elite female soccer players. Thirty-nine international female soccer players (24.3±4.7 years) performed 40-m sprints, maximal countermovement jumps and five loaded squat jumps at increasing loads to determine individual force-velocity profiles. Theoretical maximal velocity, theoretical maximal force, maximal power output, one repetition maximal back squat and one repetition maximal back squat relative to body mass were determined using the force-velocity profile. Counter movement jump, squat jump and maximal power output demonstrated moderate to large correlation with acceleration and maximal sprint speed (r=- 0.32 to -0.44 and -0.32 to -0.67 respectively, p<0.05). Theoretical maximal velocity and force, one repetition maximal and relative back squat demonstrated a trivial to small relationship to acceleration and maximal sprint speed (p>0.05). Vertical force-velocity profiling and maximal strength can provide valuable insight into the neuromuscular qualities of an athlete to individualize training, but the ability to produce force, maximal power, and further transference into sprint performance, must be central to program design.
爆发力是足球表现的重要组成部分，高度受产生最大力量的能力影响。本研究的目的是调查优秀女性足球运动员的力量-速度曲线、跳跃表现、加速度和最大冲刺速度之间的关系。39 名国际女性足球运动员（24.3±4.7 岁）进行了 40 米冲刺、最大反跳和 5 次递增负荷深蹲跳，以确定个体的力量-速度曲线。使用力量-速度曲线确定理论最大速度、理论最大力量、最大功率输出、一次重复最大深蹲和一次重复最大深蹲相对于体重。反跳、深蹲跳和最大功率输出与加速度和最大冲刺速度呈中度至高度相关（r=-0.32 至-0.44 和-0.32 至-0.67，p<0.05）。理论最大速度和力量、一次重复最大和相对深蹲与加速度和最大冲刺速度的关系较小（p>0.05）。垂直力量-速度分析和最大力量可以为运动员的神经肌肉素质提供有价值的见解，以实现个性化训练，但产生力量、最大功率的能力以及进一步转移到冲刺表现，必须是方案设计的核心。
