Running-related injury occurs frequently in collegiate cross-country runners. Hip strength is one factor that may be important in the rehabilitation and training of cross-country runners. However, no normative values exist to inform these strategies.
To establish normative values for hip-abduction and external-rotation isometric strength in collegiate cross-country runners and explore the association between strength and previous injury.
Mixed methods using descriptive epidemiology and retrospective cross-sectional designs.
University laboratory.
Eighty-two National Collegiate Athletic Association Division III cross-country runners (38 males, 44 females).
MAIN OUTCOME MEASURE(S): Isometric hip strength and reported injury.
Males demonstrated greater absolute hip strength than females. Measures of hip strength were not different between sexes when normalized to height and mass. Hip-abduction asymmetry was associated with a previous injury in males. A combination of at least 1 leg with hip-abduction weakness and bilateral external-rotation weakness was associated with a previous injury in females.
Knowledge of normative values of hip strength may help inform rehabilitation strategies in collegiate cross-country runners. Males and females may demonstrate different strength profiles after running-related injury.
在大学生越野跑运动员中，经常会发生与跑步相关的损伤。髋关节力量是越野跑运动员康复和训练中一个重要的因素。然而，目前还没有用于指导这些策略的规范值。
建立大学生越野跑运动员髋关节外展和外旋等速力量的正常值，并探讨力量与既往损伤之间的关系。
采用描述性流行病学和回顾性横断面设计的混合方法。
大学实验室。
82 名美国大学生体育协会第三分部越野跑运动员（男性 38 名，女性 44 名）。
等速髋关节力量和报告的损伤。
男性的绝对髋关节力量明显大于女性。当按身高和体重进行标准化后，男女之间的髋关节力量测量值没有差异。髋关节外展的不对称性与男性的既往损伤有关。在女性中，至少有 1 条腿的髋关节外展力量减弱和双侧外旋力量减弱与既往损伤有关。
了解髋关节力量的正常值可能有助于为大学生越野跑运动员的康复策略提供信息。男性和女性在与跑步相关的损伤后可能表现出不同的力量特征。
