Force-velocity profile (FVP) and repeated-sprint ability (RSA) tests are indicators of physical capacities in most team sport players. The purpose of this study was to examine the stride kinematics during a repeated-sprint ability (RSA) test and to analyze the relationship between Bosco's force-velocity profile (FVP) and RSA performance in elite female field hockey players. Thirteen elite-female players performed both RSA (six 30 m maximal sprints) and jumping (CMJ weighted and body weight) tests. Sprinting time fatigue indexes during a 30 m RSA test were correlated with step frequency fatigue indexes (r > 0.7; < 0.01). CMJ50 showed a large relationship with sprint time fatigue indexes. FV50 showed a very large relationship with sprint time fatigue indexes (r > 0.7; < 0.01), and a large relationship with the step frequency fatigue indexes (r > 0.5; < 0.05). This study highlighted two possible ways to improve fatigue indexes in RSA, with the aim of maximizing the distances covered at high-intensities during the matches: (a) strength training and (b) focusing on step frequency during speed training.
力量-速度曲线（FVP）和重复冲刺能力（RSA）测试是大多数团队运动运动员身体能力的指标。本研究的目的是检查重复冲刺能力（RSA）测试中的步幅运动学，并分析博斯科 FVP 与精英女子曲棍球运动员 RSA 表现之间的关系。13 名精英女运动员进行了 RSA（6 次 30 米最大冲刺）和跳跃（CMJ 加权和体重）测试。30 米 RSA 测试中的冲刺时间疲劳指数与步频疲劳指数（r>0.7；<0.01）相关。CMJ50 与冲刺时间疲劳指数呈很大关系。FV50 与冲刺时间疲劳指数呈很强关系（r>0.7；<0.01），与步频疲劳指数呈较大关系（r>0.5；<0.05）。本研究强调了两种可能的方法来提高 RSA 中的疲劳指数，目的是在比赛中最大限度地提高高强度运动的距离：（a）力量训练，（b）在速度训练中注重步频。
