目的:确定和比较流行病学,临床特征,和受伤的严重程度在不同的超跑距离的比赛参赛者训练。
方法:回顾性横断面研究。
方法:2022年MacUltra比赛前的六个月训练期(46公里,80公里,161公里和322公里)。
方法:在245名参赛者中,162人(66%的Mac超跑运动员)同意分析他们的数据。
方法:受伤率(每1000小时跑步受伤),点患病率(当前受伤参与者的百分比),损伤严重程度(时间损失),和频率(n,%)在比赛前六个月的赛前医疗筛查中报告的伤害。使用推理统计,我们比较了不同比赛距离类别(46公里,80公里,161公里,322公里)。所有测试均以5%的显著性水平进行。
结果:我们报告了46公里研究参与者的受伤率(每1000小时3.09次受伤),与80公里(每1000小时0.68次受伤;p=0.001)和161公里(每1000小时1.09次受伤;p=0.028)参与者的受伤率相比,差异有统计学意义。下肢(89%)是最受伤的解剖区域,只有46公里的研究参与者报告上肢,树干,头部受伤(11%)。肌肉/肌腱是报告最多的受伤组织类型(56%),肌肉损伤(31%)是报告最多的病理类型。短距离超跑运动员受伤严重程度最高。
结论:Ultra-trailrunner训练较短的超步道距离比赛具有较高的受伤率,更多样化的伤害特征,和更高的伤害严重程度。
OBJECTIVE: Determine and compare the epidemiology, clinical characteristics, and injury severity among race entrants training towards different ultra-trail race distances.
METHODS: Retrospective cross-sectional study.
METHODS: The six months training period before the 2022 Mac Ultra races (46 km, 80 km, 161 km and 322 km).
METHODS: Of the 245 race entrants, 162 (66% of Mac ultra-trail runners) consented to analyse their data.
METHODS: Injury rate (injuries per 1000 h of running), point prevalence (% of currently injured participants), injury severity (time loss), and the frequency (n, %) of injuries reported during pre-race medical screening in the six months before the race. Using inferential statistics, we compared the injury rates between the different race distance categories (46 km, 80 km, 161 km, 322 km). All tests were performed at a 5% level of significance.
RESULTS: We reported a statistically significantly higher injury rate among 46 km study participants (3.09 injuries per 1000 h) compared to the injury rates reported among 80 km (0.68 injuries per 1000 h; p = 0.001) and 161 km (1.09 injuries per 1000 h; p = 0.028) participants. The lower limb (89%) was the most injured anatomical region, with only 46 km study participants reporting upper limb, trunk, and head injuries (11%). Muscle/tendon was the most reported injured tissue type (56%), with muscle injuries (31%) the most reported pathology type. Shorter distance ultra-trail runners reported the highest injury severity.
CONCLUSIONS: Ultra-trail runners training towards shorter ultra-trail distance races presented with a higher injury rate, more diverse injury profile, and a higher injury severity.
