Fields, JB, Kuhlman, NM, Jagim, AR, Dulak-Sigler, C, and Jones, MT. Analysis of accumulated workloads and performance testing across a collegiate women's lacrosse season. J Strength Cond Res 37(11): 2213-2221, 2023-Monitoring accumulated workloads, acute:chronic workload ratios (ACWR), and training monotony (TM) are practical methods for monitoring athlete physical stress. Performance testing provides useful information about the changing nature of physical abilities. Therefore, the purpose was to examine differences in accumulated workloads based on session type, explore seasonal trends in ACWR and TM, and assess changes in performance assessments in collegiate women's lacrosse athletes. Athletes, who were identified as starters ( n = 12), wore positional monitoring technology during training sessions ( n = 61) and games ( n = 17) and completed preseason and postseason assessments of speed, agility, power (jump tests), strength, aerobic capacity, and body composition. Separate 1-way analyses of variance were used to determine differences in accumulated workloads for session type and differences in performance assessments from preseason to postseason ( p < 0.05). When compared with games, practice sessions elicited greater ( p < 0.001) accumulated total distance, player load, repeated high-intensity efforts, accelerations, change of direction, explosive efforts, high-speed efforts ( p = 0.002), and high-speed distance ( p = 0.002). Throughout the season, ACWR and TM ranged from 0.16 to 1.40 AU and 0.68-1.69 AU, respectively. The 40-yd sprint ( p < 0.001) and pro-agility ( p < 0.001) improved from preseason to postseason, whereas no changes in aerobic capacity, lower-body power, or strength were observed ( p > 0.05). The monitoring of accumulated loads, ACWR and TM, and performance tests revealed novel information about the seasonal demands of collegiate women's lacrosse. Women lacrosse players are able to improve speed and agility throughout the season, while maintaining strength, power, and endurance, with minimal reductions in fat-free mass.
菲尔兹，JB，库尔曼，NM，贾吉姆，AR，杜拉克-西格勒，C，琼斯，MT。对大学女子长曲棍球赛季中累积工作量和性能测试的分析。J 力量与体能研究 37（11）：2213-2221，2023-监测累积工作量、急性：慢性工作量比（ACWR）和训练单调（TM）是监测运动员身体压力的实用方法。性能测试提供了有关身体能力不断变化的有用信息。因此，目的是根据会话类型检查累积工作量的差异，探讨 ACWR 和 TM 的季节性趋势，并评估大学女子长曲棍球运动员的性能评估变化。确定为首发球员的运动员（n=12）在训练课（n=61）和比赛（n=17）中佩戴位置监测技术，并完成速度、敏捷性、力量（跳跃测试）、力量、有氧能力和身体成分的赛季前和赛后评估。使用单向方差分析来确定会话类型的累积工作量差异和赛季前到赛季后的性能评估差异（p<0.05）。与比赛相比，练习课产生了更大的累积总距离（p<0.001）、球员负荷、重复高强度努力、加速度、变向、爆发力、高速努力（p=0.002）和高速距离（p=0.002）。在整个赛季中，ACWR 和 TM 的范围分别为 0.16 至 1.40 AU 和 0.68 至 1.69 AU。40 码冲刺（p<0.001）和职业敏捷性（p<0.001）从赛季前到赛季后都有所提高，而有氧能力、下半身力量或力量没有变化（p>0.05）。累积负荷、ACWR 和 TM 以及性能测试的监测揭示了关于大学女子长曲棍球赛季需求的新信息。女子长曲棍球运动员能够在整个赛季中提高速度和敏捷性，同时保持力量、爆发力和耐力，而脂肪量减少很少。
