Injury management is critical in the National Basketball Association (NBA), as players experience a wide variety of injuries. Recently, it has been suggested that game schedules, such as back-to-back games and four games in five days, increase the risk of injuries in the NBA. The aim of this study was to examine the association between game schedules and player injuries in the NBA.
Descriptive epidemiology study.
The present study analyzed game injuries and game schedules in the 2012-13 through 2014-15 regular seasons. Game injuries by game schedules and players' profiles were examined using an exact binomial test, the Fisher's exact test and the Mann-Whitney-Wilcoxon test. A Poisson regression analysis was performed to predict the number of game injuries sustained by each player from game schedules and injured players' profiles.
There were a total of 681 cases of game injuries sustained by 280 different players during the three years (total N=1443 players). Playing back-to-back games or playing four games in five days alone was not associated with an increased rate of game injuries, whereas a significant positive association was found between game injuries and playing away from home (p<0.05). Playing back-to-back games and away games were significant predictors of frequent game injuries (p<0.05).
Game schedules could be one factor that impacts the risk of game injuries in the NBA. The findings could be useful for designing optimal game schedules in the NBA as well as helping NBA teams make adjustments to minimize game injuries.
在国家篮球协会（NBA）中，伤病管理至关重要，因为球员会遭遇各种各样的伤病。最近，有人提出诸如背靠背比赛以及五天内打四场比赛等赛程安排会增加NBA球员受伤的风险。本研究的目的是检验NBA赛程安排与球员伤病之间的关联。
描述性流行病学研究。
本研究分析了2012 - 13赛季至2014 - 15赛季常规赛中的比赛伤病情况和赛程安排。使用精确二项式检验、费舍尔精确检验以及曼 - 惠特尼 - 威尔科克森检验，对按赛程安排和球员资料划分的比赛伤病情况进行了检查。进行了泊松回归分析，以根据赛程安排和受伤球员资料预测每名球员遭受的比赛伤病数量。
在这三年间，280名不同球员共出现了681例比赛伤病（总球员数N = 1443）。单独的背靠背比赛或五天内打四场比赛与比赛伤病率增加并无关联，然而，比赛伤病与客场比赛之间存在显著的正相关（p < 0.05）。背靠背比赛和客场比赛是频繁出现比赛伤病的显著预测因素（p < 0.05）。
赛程安排可能是影响NBA比赛伤病风险的一个因素。这些研究结果对于设计NBA的最佳赛程安排以及帮助NBA球队进行调整以尽量减少比赛伤病可能会有所帮助。
