BACKGROUND
Load management is a sports science concept describing the execution of well-established training principles to measure athletic workloads and enhance performance. The term 'load management' has become common in sports media to refer to a much wider range of scenarios, including the idea that by limiting regular season workload for athletes, their health and playoff performance will improve. Varying links between load and performance have been demonstrated in baseball and soccer. The purpose of this study was to objectively assess the impact of regular season workload on postseason performance among National Hockey League (NHL) goalies.
HYPOTHESIS
NHL goalies with lighter regular season workloads will perform better in postseason appearances.
STUDY DESIGN
Retrospective cohort.
LEVEL OF EVIDENCE
Level 3.
METHODS
NHL goalies with a minimum of 20 regular season games played and 3 playoff game appearances in the same season since 2013-2014 were eligible for inclusion. All regular season and postseason workload and performance metrics were collected from publicly available statistical databases. Workload outcomes included games started, minutes played, and shots faced. Performance outcomes included goals against average, save percentage, goals saved above average, and quality start percentage. Multivariable linear regression was used to determine whether regular season workload predicted postseason performance, when controlling for age and injury status.
RESULTS
A total of 51 goalies contributed 111 goalie-seasons to the analysis. The results of the primary model indicated that regular season workload explained only 6.8% of the variance in postseason performance, and that this relationship was not significant ( = 0.068; (5,92) = 1.335; = 0.26).
CONCLUSION
Based on data from 6 full seasons, there is no evidence to support a specific regular season game limit among NHL goalies with the aim of improved performance.
CLINICAL RELEVANCE
Individualized workload plans may be more appropriate than a single league-wide standard.
背景
负荷管理是一个体育科学概念，描述了运用成熟的训练原则来衡量运动员的工作量并提高成绩。“负荷管理”一词在体育媒体中已很常见，但其所指的场景范围要广泛得多，包括这样一种观点，即通过限制运动员常规赛的工作量，他们的健康状况和季后赛表现将会得到改善。在棒球和足球运动中，负荷与表现之间存在着不同的联系。本研究的目的是客观评估国家冰球联盟（NHL）守门员常规赛工作量对季后赛表现的影响。
假设
常规赛工作量较轻的NHL守门员在季后赛中的表现会更好。
研究设计
回顾性队列研究。
证据级别
3级。
方法
自2013 - 2014赛季以来，在同一赛季中至少参加20场常规赛且有3次季后赛出场的NHL守门员符合纳入标准。所有常规赛和季后赛的工作量及表现指标均从公开的统计数据库中收集。工作量指标包括首发场次、上场时间和面对的射门次数。表现指标包括平均失球数、扑救成功率、高于平均水平的救球数和优质开局率。在控制年龄和伤病状况的情况下，使用多变量线性回归来确定常规赛工作量是否能预测季后赛表现。
结果
共有51名守门员为该分析贡献了111个守门员赛季的数据。主要模型的结果表明，常规赛工作量仅解释了季后赛表现中6.8%的方差，且这种关系不显著（ = 0.068；(5,92) = 1.335； = 0.26）。
结论
基于6个完整赛季的数据，没有证据支持为提高表现而对NHL守门员设置特定的常规赛比赛场次限制。
临床意义
个性化的工作量计划可能比单一的全联盟标准更为合适。
