Abstract

BACKGROUND

Cheerleaders suffer nearly half of catastrophic injuries observed in female scholastic athletes in the United States. However, incidence of noncatastrophic injury in this population has not been described.

HYPOTHESIS

Coach, athlete, and injury circumstance variables may predict the injury rate among cheerleaders.

STUDY DESIGN

Prospective cohort.

METHODS

The authors investigated injury incidence in a sample of North Carolina female cheerleaders who competed inter-scholastically from 1996 to 1999. Injury, exposure, and demographic data were collected from squads that participated in the North Carolina High School Athletic Injury Study.

RESULTS

Cheerleaders suffered 133 injuries during 1701 athlete seasons. More than 21% of the injuries were ankle sprains. The injury rate was 8.7; the 95% confidence interval (CI) was 6.5 to 11.7 per 10,000 athlete exposures. In a multivariate Poisson regression model, cheerleaders supervised by coaches with the most education, qualifications, and training (coach EQT) had a nearly 50% reduction in injury risk (rate ratio [RR], 0.5; 95% CI, 0.3-0.9), and cheerleaders supervised by coaches with medium coach EQT had a nearly 40% reduction in injury risk (RR = 0.6; 95% CI, 0.3-1.2) compared to cheerleaders supervised by coaches with low coach EQT.

摘要

背景

在美国女子学校运动员中，啦啦队队员遭受的灾难性损伤占近一半。然而，这一人群中非灾难性损伤的发生率尚未得到描述。

假设

教练、运动员和损伤情况变量可能预测啦啦队队员的损伤率。

研究设计

前瞻性队列研究。

方法

作者调查了1996年至1999年在北卡罗来纳州参加校际比赛的女子啦啦队队员样本中的损伤发生率。从参与北卡罗来纳州高中体育损伤研究的队伍中收集损伤、暴露和人口统计学数据。

结果

在1701个运动员赛季中，啦啦队队员共遭受133次损伤。超过21%的损伤为脚踝扭伤。损伤率为8.7；每10000次运动员暴露的95%置信区间（CI）为6.5至11.7。在多变量泊松回归模型中，由受教育程度、资质和训练最高的教练（教练EQT）指导的啦啦队队员损伤风险降低近50%（率比[RR]，0.5；95%CI，0.3 - 0.9），与由低教练EQT的教练指导的啦啦队队员相比，由中等教练EQT的教练指导的啦啦队队员损伤风险降低近40%（RR = 0.6；95%CI，0.3 - 1.2）。
