Abstract
Objectives: This prospective cohort observational study aimed to describe the prevalence of injuries among national-level female sprinters and to explore associations between event types (curved versus straight line) and other relevant factors.
Method: A total of 81 Japanese female sprinters competing at the national level participated in this study, of whom 41 (50.6%) specialized in straight‑line events. The Oslo Sports Trauma Research Center overuse injury questionnaire was distributed every other week for 6 months (overall response rate was 46.2%). Additionally, athletes completed a survey and performed a single-leg squat test once at the beginning.
Results: During the 6 months, 39 athletes (48.2%) experienced at least one substantial health problem, with 90% of these being injuries. Athletes with substantial health problems were significantly taller, slept less, and had more often specialized in curved events. Logistic regression analysis revealed shorter sleep duration was associated with higher odds of sustaining a substantial injury (OR = 0.60, 95% CI 0.37-0.97, p = 0.04). Furthermore, athletes specializing in straight‑line events had a lower risk of substantial injuries compared to those specializing in curved events (OR = 0.19, 95% CI 0.06-0.60, p <0.01).
Conclusion: Limited sleep and specialization in curved events were significant risk factors for substantial injuries among national-level female sprinters. These findings highlight potentially important factors for injury monitoring and prevention strategies in sprint athletes, while reflecting associations observed within this cohort.
目的：本前瞻性队列观察研究旨在描述国家级女短跑运动员的损伤发生率，并探讨事件类型（曲线与直线）与其他相关因素之间的关系。方法：对81名日本国家级女子短跑运动员进行研究，其中41名（50.6%）为直线项目专业运动员。奥斯陆运动创伤研究中心的过度使用性损伤问卷每隔一周分发一次，持续6个月（总应答率为46.3%）。此外，运动员完成了一项调查，并在开始时进行了一次单腿深蹲测试。结果：在6个月期间，39名运动员（48.2%）经历了至少一次实质性的健康问题，其中90%是受伤。有严重健康问题的运动员明显更高，睡眠更少，而且更多地专门从事弯曲项目。Logistic回归分析显示，较短的睡眠时间与较高的持续严重损伤的几率相关（OR =0.60, 95% CI 0.38-0.97, p = 0.04）。此外，专门从事直线项目的运动员与专门从事曲线项目的运动员相比，实质性伤害的风险更低（OR =0.20, 95% CI 0.07-0.60, p）。结论：有限的睡眠和专门从事曲线项目是国家级女短跑运动员实质性伤害的重要危险因素。这些发现强调了短跑运动员损伤监测和预防策略的潜在重要因素，同时反映了在该队列中观察到的关联。
期刊介绍：
The Physician and Sportsmedicine is a peer-reviewed, clinically oriented publication for primary care physicians. We examine the latest drug discoveries to advance treatment and recovery, and take into account the medical aspects of exercise therapy for a given condition. We cover the latest primary care-focused treatments serving the needs of our active patient population, and assess the limits these treatments govern in stabilization and recovery.
The Physician and Sportsmedicine is a peer-to-peer method of communicating the latest research to aid primary care physicians’ advancement in methods of care and treatment. We routinely cover such topics as: managing chronic disease, surgical techniques in preventing and managing injuries, the latest advancements in treatments for helping patients lose weight, and related exercise and nutrition topics that can impact the patient during recovery and modification.
