To survey injury/illness in the National Basketball Association over a 25-year period and examine the relationship of injury/illness to team performance.
A retrospective correlational design.
Trends were examined in reported numbers of players injured/ill during a season and games missed due to injury/illness from seasons ending in 1986 through 2005. This period was compared to years 2006-2010, when NBA teams were allowed to increase the total number of players on the team from 12 to 15.
There was a highly significant trend (p<0.0001) of increasing numbers of players injured/ill and games missed from 1986 through 2005. After the team expansion in 2006, these rates fell abruptly by 13% and 39% respectively (both p<0.0001 compared to the previous 5-year period). We also found a significant inverse association between games missed due to injury/illness and percent games won (r=-0.29, p<0.0001).
Results demonstrate an increased rate of injury in the National Basketball Association up until the expansion of team size in 2006. Following 2006, team expansion was positively associated with decreased injury/illness rates. The latter finding suggests the importance of maintaining a healthy roster with respect to winning outcomes.
调查美国职业篮球联赛25年间的伤病情况，并研究伤病与球队表现之间的关系。
回顾性相关设计。
对1986年至2005年赛季期间报告的受伤/患病球员数量以及因伤病错过的比赛场次的趋势进行了研究。将这一时期与2006 - 2010年进行比较，2006 - 2010年美国职业篮球联赛球队的球员总数从12名增加到了15名。
从1986年到2005年，受伤/患病球员数量和错过的比赛场次呈高度显著的上升趋势（p<0.0001）。2006年球队扩军后，这些比率分别突然下降了13%和39%（与前一个5年时期相比，p均<0.0001）。我们还发现因伤病错过的比赛场次与获胜比赛百分比之间存在显著的负相关（r = -0.29，p<0.0001）。
结果表明，在美国职业篮球联赛中，直到2006年球队规模扩大之前，伤病率一直在上升。2006年之后，球队扩军与伤病率下降呈正相关。后一项发现表明保持健康的球员阵容对于获胜结果的重要性。
