To investigate lower extremity muscle strength as risk factor for an acute ankle injury in youth athletes.
Cohort study.
Basketball and floorball clubs.
188 youth (≤21) male and 174 female athletes.
1RM leg press, maximal concentric isokinetic quadriceps and hamstrings as well as maximal isometric hip abductor strength were measured and athletes were followed for an acute ankle injury up to three years. Cox regression models were used in statistical analyses.
In males, greater 1RM leg press and maximal quadriceps strength increased the risk of any type of acute ankle injury (Hazard ratio [HR] for 1 SD increase, 1.63 [95% CI, 1.12-2.39] and 1.43 [95% CI, 1.01-2.01], respectively). In females, greater 1RM leg press and difference between legs in hip abduction strength increased the risk of acute non-contact ankle injury (HR for 1 SD increase, 1.44 [95% CI, 1.03-2.02] and 1.44 [95% CI, 1.03-2.00], respectively). However, ROC curve analyses showed AUC:s of 0.57-0.64 indicating "fail" to "poor" combined sensitivity and specifity of these tests.
Greater strength in both sexes along with asymmetry in hip abductor strength in females increased the risk of acute ankle injury.
探究下肢肌肉力量是否为青年运动员急性踝关节损伤的风险因素。
队列研究。
篮球和地板球俱乐部。
188 名男性和 174 名女性青年（≤21 岁）运动员。
1 次最大重复腿部按压、最大向心等速股四头肌和腘绳肌力量以及最大等长髋关节外展力量进行测量，并随访运动员 3 年内是否发生急性踝关节损伤。采用 Cox 回归模型进行统计分析。
在男性中，1RM 腿部按压和最大股四头肌力量的增加会增加任何类型的急性踝关节损伤风险（1SD 增加的风险比[HR]，1.63[95%CI，1.12-2.39]和 1.43[95%CI，1.01-2.01]）。在女性中，1RM 腿部按压和髋关节外展力量的双腿差异会增加急性非接触性踝关节损伤的风险（1SD 增加的 HR，1.44[95%CI，1.03-2.02]和 1.44[95%CI，1.03-2.00]）。然而，ROC 曲线分析显示 AUC 为 0.57-0.64，表明这些测试的综合灵敏度和特异性为“失败”至“较差”。
两性的力量增加以及女性髋关节外展力量的不对称性会增加急性踝关节损伤的风险。
