Abstract：
OBJECTIVE: To describe the frequency, type, and severity of health problems in long-track speed skating to inform injury prevention strategies.
METHODS: We prospectively collected weekly health and sport exposure data on 84 highly trained Dutch athletes aged 15-21 years during the 2019/2020 season using the Oslo Sports Trauma Research Centre questionnaire on Health Problems and the trainers\' documentation. We categorised health problems into acute or repetitive mechanisms of injury or illness and calculated incidences (per 1000 sports exposure hours), weekly prevalence and burden (days of time loss per 1000 sports exposure hours) related to the affected body region.
RESULTS: We registered 283 health problems (187 injuries, 96 illnesses), yielding an average weekly prevalence of health problems of 30.5% (95% CI 28.7% to 32.2%). Incidence rates were 2.0/1000 hours for acute mechanism injuries (95% CI 1.5 to 2.5) and 3.2/1000 hours for illnesses (95% CI 2.6 to 3.9). For acute mechanism injuries the head, shoulder and lumbosacral region had the highest injury burden of 5.6 (95% CI 4.8 to 6.5), 2.9 (95% CI 2.3 to 3.5) and 2.2 (95% CI 1.7 to 2.8) days of time loss/1000 hours, respectively. For repetitive mechanism injuries, the knee, thoracic spine, lower leg and lumbosacral region had the highest injury burden, with 11.0 (95% CI 9.8 to 12.2), 6.8 (95% CI 5.9 to 7.7), 3.9 (95% CI 3.2 to 4.6) and 2.5 (95% CI 1.9 to 3.1) days of time loss/1000 hours, respectively.
CONCLUSIONS: Our study demonstrated a high prevalence of acute and repetitive mechanism injuries in speed skating. These results can guide future research and priorities for injury prevention.

摘要：
目的：为了描述频率，type,以及长道速滑中健康问题的严重性，以告知伤害预防策略。
方法：我们前瞻性地收集了2019/2020赛季期间84名训练有素的15-21岁荷兰运动员的每周健康和运动暴露数据，使用奥斯陆运动创伤研究中心关于健康问题的问卷和培训师的文件。我们将健康问题分类为急性或重复的损伤或疾病机制，并计算发生率（每1000个运动暴露小时），与受影响的身体区域相关的每周患病率和负担（每1000个运动暴露小时的时间损失天数）。
结果：我们记录了283个健康问题（187人受伤，96种疾病），健康问题的平均每周患病率为30.5%(95%CI28.7%至32.2%)。急性机制损伤的发生率为2.0/1000小时（95％CI1.5至2.5），疾病的发生率为3.2/1000小时（95％CI2.6至3.9）。对于头部的急性机制损伤，肩部和腰骶部的损伤负担最高，为5.6（95%CI4.8～6.5），2.9（95％CI2.3至3.5）和2.2（95％CI1.7至2.8）天的时间损失/1000小时，分别。对于重复性机制损伤，膝盖,胸椎,小腿和腰骶部的损伤负担最高，11.0（95%CI9.8至12.2），6.8（95%CI5.9至7.7），3.9（95％CI3.2至4.6）和2.5（95％CI1.9至3.1）天的时间损失/1000小时，分别。
结论：我们的研究表明，速滑运动中急性和重复机制损伤的患病率很高。这些结果可以指导未来的研究和损伤预防的重点。
