Sutton, PJ, Mumford, PW, and Sunderland, KL. Workloads in collegiate women's lacrosse athletes during a Division II national championship season. J Strength Cond Res 38(9): 1651-1657, 2024-A comprehensive examination of the external and internal workloads in collegiate women's lacrosse athletes has yet to be reported. Thus, the primary purpose of this study was to determine the absolute and relative external and internal training and game workloads of National Collegiate Athletic Association (NCAA) Division II women's lacrosse athletes throughout an entire season. Data from 19 Division II women's lacrosse athletes were analyzed, encompassing each training session and game across an entire competitive season (February-May). External workloads were assessed using a wearable global positioning system, whereas internal workloads were determined through heart rate (HR) variables and session rating of perceived exertion. Game days were associated with significantly ( p < 0.05) greater absolute external and internal workloads. However, when comparing workloads relative to session duration, relative workloads between training and games were no longer significant ( p > 0.05) for total distance, high-speed running (≥15 km·h -1 ), HR-derived training impulse, or caloric expenditure. Nonetheless, relative sprint distance (>19 km·h -1 ) was significantly lower during games, whereas high-intensity accelerations (>2 m·s -2 ) and decelerations (<-2 m·s -2 ) were significantly greater during training compared with games ( p < 0.05). Practical applications of these findings suggest that coaches can better prepare athletes for game day conditions by adjusting training plans to replicate the duration and intensity of games. Overall, this comprehensive examination of internal and external workloads provides valuable data for coaches and practitioners to support performance comparisons, rehabilitation protocols, and workload analyses in collegiate women's lacrosse athletes.
萨顿、PJ、芒福德、PW 和桑德兰德、KL。二级全国锦标赛赛季中大学女子长曲棍球运动员的工作量。J 强质研究 38(9)：1651-1657，2024-尚未报道对大学生女子长曲棍球运动员的外部和内部工作量进行全面检查。因此，本研究的主要目的是确定 NCAA 二级女子长曲棍球运动员整个赛季的绝对和相对外部和内部训练和比赛工作量。分析了 19 名二级女子长曲棍球运动员的数据，涵盖了整个比赛赛季（2 月至 5 月）的每次训练和比赛。使用可穿戴式全球定位系统评估外部工作量，而通过心率（HR）变量和训练感觉用力评分确定内部工作量。比赛日与绝对外部和内部工作量显著增加（p < 0.05）相关。然而，当将工作量与会话持续时间进行比较时，训练和比赛之间的相对工作量不再显著（p > 0.05），总距离、高速跑动（≥15 km·h -1 ）、HR 衍生的训练冲动或卡路里消耗。尽管如此，比赛中相对冲刺距离（>19 km·h -1 ）明显较低，而训练中高强度加速度（>2 m·s -2 ）和减速（<-2 m·s -2 ）明显高于比赛（p < 0.05）。这些发现的实际应用表明，教练可以通过调整训练计划来复制比赛的持续时间和强度，更好地为运动员准备比赛日的条件。总体而言，对内部和外部工作量的全面检查为教练和从业者提供了有价值的数据，以支持大学女子长曲棍球运动员的表现比较、康复方案和工作量分析。
