Abstract

Objective: To identify strength and flexibility measures that are associated with the risk of running-related overuse injuries.

Design: Prospective observational study.

Setting: Secondary analysis of a previously reported cohort of runners.

Participants: Runners registered for the 2019 New York City Marathon.

Independent variables: Participants were asked to complete a baseline strength and flexibility self-assessment 16 weeks before the marathon date.

Main outcome measure: Participants were asked to respond to surveys on running-related injuries occurring within 4-week "training quarters" at 16, 8, 4, and 1 week(s) before the marathon date.

Results: Of the n = 867 runners included in our final analytic sample, 36.1% sustained a running-related overuse injury while preparing for the marathon. The only significant difference in odds and/or hazard of injury was found in the single-leg glute bridge test. Participants who reported that they could hold a single-leg glute bridge on their weaker side for 20 to 29 seconds had 64% lower risk of running-related overuse injury (aHR: 0.36; 95% CI, 0.18-0.72; P = 0.0036) than those who could only hold for 0 to 9 seconds on their weaker side. In addition, participants who reported that they could hold a single-leg glute bridge on their weaker side for 30 seconds or more had 49% lower risk of running-related overuse injury (aHR: 0.51; 95% CI, 0.29-0.92; P = 0.0245).

Conclusions: Strength training programs, particularly targeting hip abductors and related muscle groups, may provide benefits for distance runners, though more rigorous research is needed.

纽约马拉松选手力量柔韧性自我评估及后续训练损伤。
目的:确定与跑步相关的过度使用损伤风险相关的力量和柔韧性措施。设计:前瞻性观察研究。背景:对先前报道的跑步者队列进行二次分析。参与者:报名参加2019年纽约市马拉松赛的选手。独立变量:参与者被要求在马拉松赛前16周完成基线力量和柔韧性自我评估。主要结果测量:参与者被要求在马拉松日期前16、8、4和1周的4周“训练季度”内对与跑步相关的伤害进行调查。结果:在我们最终分析样本的n = 867名跑步者中,36.1%的人在准备马拉松比赛时遭受了与跑步相关的过度使用损伤。损伤几率和/或危险的唯一显著差异是在单腿臀肌桥试验中。参与者报告说,他们可以在较弱的一侧保持单腿臀肌桥20到29秒,与跑步相关的过度使用损伤的风险降低了64% (aHR: 0.36;95% ci, 0.18-0.72;P = 0.0036)比那些只能用弱侧保持0到9秒的人要好。此外,参与者报告说,他们可以用弱侧支撑单腿臀肌桥30秒或更长时间,与跑步相关的过度使用损伤的风险降低了49% (aHR: 0.51;95% ci, 0.29-0.92;P = 0.0245)。结论:力量训练计划,特别是针对髋关节外展肌群和相关肌肉群,可能对长跑运动员有益,尽管需要更严格的研究。
