To identify whether baseline differences in hip and knee isometric strength exist among female runners who sustained a running related injury (RRI) and those that remained injury-free during a 16-week formalized training program.
Prospective Cohort.
Laboratory Setting.
54 healthy female recreational runners enrolled in a formalized training program for half or full marathon. At the conclusion of the program, 50 female runners (age: 39.1 ± 9.4 years; height: 165.3 ± 7.4 cm; mass: 64.8 ± 11.9 kg) were included in analysis.
Peak isometric torque of knee flexion and extension, hip flexion and extension, and hip abduction and external rotation were compared between runners who sustained an RRI and injury-free (INJF) runners.
15 of the 50 participants developed an RRI during the observational period, no between groups differences existed for any demographic variable. Hip and knee isometric strength was not different prior to the start of a 16-week formalized training program between runners who sustained an RRI and those that remained injury-free.
Hip and knee weakness does not appear to be a baseline characteristic among female recreational runners who sustained an RRI or remained uninjured while training for a half or full marathon.
确定在一项为期16周的正规训练计划中，遭受跑步相关损伤（RRI）的女性跑步者与未受伤的女性跑步者之间，髋部和膝部等长肌力在基线时是否存在差异。
前瞻性队列研究。
实验室环境。
54名参加半程或全程马拉松正规训练计划的健康女性休闲跑步者。在该计划结束时，50名女性跑步者（年龄：39.1±9.4岁；身高：165.3±7.4厘米；体重：64.8±11.9千克）纳入分析。
比较遭受RRI的跑步者与未受伤（INJF）的跑步者之间，膝部屈伸、髋部屈伸以及髋部外展和外旋的等长扭矩峰值。
50名参与者中有15名在观察期内发生了RRI；在任何人口统计学变量上，两组之间均无差异。在为期16周的正规训练计划开始前，遭受RRI的跑步者与未受伤的跑步者之间，髋部和膝部等长肌力并无差异。
髋部和膝部力量不足似乎并非遭受RRI的女性休闲跑步者的基线特征，她们在进行半程或全程马拉松训练时或者未受伤。
