The purpose of this study was to analyse the relationship between external load metrics with game performance for Division I collegiate female lacrosse. Data were collected using microtechnology during 26 games with 13 athletes (attackers = 5, midfielders = 8). External load variables included: total distance (TD), distance rate (DR), high-intensity (HI) distance, speed, HI sprints, accelerations, decelerations, metabolic equivalent distance (MED), and sprints. For attackers, goals, points, shots, and shots on goal (SOG) had low, positive associations with TD ( = 0.32 to 0.42) and MED ( = 0.39 to 0.45). For midfielders, goals, shots, and draw controls had low, positive relationships with TD ( = 0.34 to 0.41), DR ( = 0.33 to 0.45), and decelerations ( = 0.30 to 0.35). Points and SOG had low associations with TD ( = 0.35), DR ( = 0.33), accelerations ( = 0.31), and decelerations ( = 0.32 to 0.35). Turnovers demonstrated low, positive relationships with HI distance ( = 0.31) and HI sprints ( = 0.41). Though the correlations were low, they still revealed insights into workload metrics and offensive game statistics in the sport of lacrosse. Training for attackers should focus on agility and a training base for TD. Training for midfielders should focus on HI endurance and sprinting.
本研究的目的是分析美国大学体育协会（NCAA）一级联盟女子长曲棍球比赛中外部负荷指标与比赛表现之间的关系。在26场比赛中，使用微技术收集了13名运动员（5名攻击手、8名中场球员）的数据。外部负荷变量包括：总距离（TD）、距离速率（DR）、高强度（HI）距离、速度、HI冲刺、加速度、减速度、代谢当量距离（MED）和冲刺次数。对于攻击手，进球数、得分、射门次数和射正次数与TD（=0.32至0.42）和MED（=0.39至0.45）呈低强度正相关。对于中场球员，进球数、射门次数和争球控制次数与TD（=0.34至0.41）、DR（=0.33至0.45）和减速度（=0.30至0.35）呈低强度正相关。得分和射正次数与TD（=0.35）、DR（=0.33）、加速度（=0.31）和减速度（=0.32至0.35）呈低强度相关。失误次数与HI距离（=0.31）和HI冲刺次数（=0.41）呈低强度正相关。尽管相关性较低，但它们仍揭示了长曲棍球运动中工作量指标与进攻比赛统计数据之间的关系。对攻击手的训练应侧重于敏捷性和TD的训练基础。对中场球员的训练应侧重于HI耐力和短跑。
