Poor core stability is believed to increase vulnerability to uncontrolled joint displacements throughout the kinetic chain between the foot and the lumbar spine.
To assess the value of preparticipation measurements as predictors of core or lower extremity strains or sprains in collegiate football players.
Cohort study.
National Collegiate Athletic Association Division I Football Championship Subdivision football program.
All team members who were present for a mandatory physical examination on the day before preseason practice sessions began (n = 83).
MAIN OUTCOME MEASURE(S): Preparticipation administration of surveys to assess low back, knee, and ankle function; documentation of knee and ankle injury history; determination of body mass index; 4 different assessments of core muscle endurance; and measurement of step-test recovery heart rate. All injuries were documented throughout the preseason practice period and 11-game season. Receiver operating characteristic analysis and logistic regression analysis were used to identify dichotomized predictive factors that best discriminated injured from uninjured status. The 75th and 50th percentiles were evaluated as alternative cutpoints for dichotomization of injury predictors.
Players with ≥2 of 3 potentially modifiable risk factors related to core function had 2 times greater risk for injury than those with <2 factors (95% confidence interval = 1.27, 4.22), and adding a high level of exposure to game conditions increased the injury risk to 3 times greater (95% confidence interval = 1.95, 4.98). Prediction models that used the 75th and 50th percentile cutpoints yielded results that were very similar to those for the model that used receiver operating characteristic-derived cutpoints.
Low back dysfunction and suboptimal endurance of the core musculature appear to be important modifiable football injury risk factors that can be identified on preparticipation screening. These predictors need to be assessed in a prospective manner with a larger sample of collegiate football players.
人们认为核心稳定性差会增加整个足-腰椎动力链中关节不受控制的位移的易感性。
评估参赛前测量值作为预测大学橄榄球运动员核心或下肢拉伤或扭伤的指标的价值。
队列研究。
美国全国大学体育协会一级足球分区锦标赛足球项目。
所有在季前训练开始前的某一天参加强制性体检的队员（n=83）。
参赛前进行的调查，以评估下腰痛、膝痛和踝关节功能；记录膝关节和踝关节受伤史；确定身体质量指数；4 种不同的核心肌肉耐力评估；以及测试后恢复心率的台阶测试。所有损伤均在季前训练期间和 11 场比赛赛季中记录。使用受试者工作特征分析和逻辑回归分析来确定最佳区分受伤和未受伤状态的二分预测因素。第 75 和 50 百分位数用于评估二分化损伤预测因素的替代切点。
与核心功能相关的 3 个潜在可改变的危险因素中，≥2 个危险因素的运动员受伤的风险是危险因素<2 个的运动员的 2 倍（95%置信区间=1.27，4.22），并且增加高水平的比赛条件暴露会使受伤风险增加 3 倍（95%置信区间=1.95，4.98）。使用第 75 和 50 百分位数切点的预测模型得出的结果与使用受试者工作特征衍生切点的模型非常相似。
下腰痛功能障碍和核心肌肉耐力不足似乎是重要的可改变的足球损伤危险因素，可以在参赛前筛查中确定。这些预测因素需要在更大的大学生橄榄球队员样本中进行前瞻性评估。
