To determine the normal profiles for hip strength and range of motion (ROM) in a professional football league in Qatar, and examine the effect of leg dominance, age, past history of injury, and ethnicity on these profiles.
Cross-sectional cohort study.
Participants included 394 asymptomatic, male professional football players, aged 18-40 years. Strength was measured using a hand held dynamometer with an eccentric test in side-lying for hip adduction and abduction, and the squeeze test in supine with 45° hip flexion. Range of motion measures included: hip internal and external rotation in 90° flexion, hip IR in prone, bent knee fall out and hip abduction in side-lying. Demographic information was collected and the effect on the profiles was analysed using linear mixed models with repeated measures.
Strength values (mean±SD) were: adduction=3.0±0.6Nm/kg, abduction=2.6±0.4Nm/kg, adduction/abduction ratio=1.2±0.2, Squeeze test=3.6±0.8N/kg. Range of motion values: internal rotation in flexion=32±8°, external rotation=38±8°, internal rotation in prone=38±8°, bent knee fall out=13±4.4cm, abduction in side-lying=50±7.3°. Leg dominance had no clinically relevant effect on these profiles. Multivariate analysis demonstrated that age had a minor influence on squeeze strength (-0.03N/kg/year), external rotation (-0.30°/year) and abduction range (-0.19°/year) but past history of injury, and ethnicity did not.
Normal values are documented for hip strength and range of motion that can be used as reference profiles in the clinical assessment, screening, and management of professional football players. Leg dominance, recent past injury history and ethnicity do not need to be accounted for when using these profiles for comparison purposes.
确定卡塔尔某职业足球联赛中髋部力量和活动范围（ROM）的正常概况，并研究腿侧优势、年龄、既往受伤史和种族对这些概况的影响。
横断面队列研究。
参与者包括394名无症状的男性职业足球运动员，年龄在18至40岁之间。使用手持测力计测量力量，侧卧位时进行髋内收和外展的离心测试，仰卧位时进行45°髋关节屈曲的挤压测试。活动范围测量包括：90°屈曲时的髋内旋和外旋、俯卧位时的髋内旋、屈膝外展和侧卧位时的髋外展。收集人口统计学信息，并使用重复测量的线性混合模型分析对概况的影响。
力量值（均值±标准差）为：内收=3.0±0.6牛米/千克，外展=2.6±0.4牛米/千克，内收/外展比值=1.2±0.2，挤压测试=3.6±0.8牛/千克。活动范围值：屈曲时内旋=32±8°，外旋=38±8°，俯卧位时内旋=38±8°，屈膝外展=13±4.4厘米，侧卧位时外展=50±7.3°。腿侧优势对这些概况没有临床相关影响。多变量分析表明，年龄对挤压强度（-0.03牛/千克/年）、外旋（-0.30°/年）和外展范围（-0.19°/年）有轻微影响，但既往受伤史和种族没有影响。
记录了髋部力量和活动范围的正常值，可作为职业足球运动员临床评估、筛查和管理的参考概况。在使用这些概况进行比较时，无需考虑腿侧优势、近期受伤史和种族。
