Objective To analyse associations between feels-like temperatures measured with the universal thermal climate index (UTCI) and injury rates during international athletic championships. Methods During 10 international outdoor athletic championships from 2007 to 2022, in-competition injuries were collected by medical teams and local organising committees. UTCI was extracted hourly from a global reanalysis of observed atmospheric conditions during each championship. We performed Poisson regressions with incidence rates (number of injuries per 1000 athlete starts) as outcomes and UTCI as a predictive variable adjusted for sex, for all and time-loss injuries, for different injured tissue types (ie, muscle, tendon, ligament, articular, bone and skin) and specific discipline (ie, sprints, hurdles, jumps, throws, middle distance, long distance, marathon and race walking). Results A total of 1203 in-competition injuries were reported for 29 579 athlete starts. For all in-competition injuries (ie, all injured tissue types and all disciplines), higher UTCI was associated with lower incidence rates for time-loss injuries (IRR=0.98, 95% CI 0.97 to 0.98) but not for all injuries (IRR=1.00, 95% CI 1.00 to 1.01). Based on injured tissue type with all disciplines included, higher UTCI was associated with lower incidence rates for all (IRR=0.97, 95% CI 0.97 to 0.98) and time-loss (IRR=0.96, 95% CI 0.96 to 0.96) muscle injuries. Based on the specific discipline, higher UTCI was associated with lower incidence rates for all and time-loss muscle injuries for sprints (IRR=0.95, 95% CI 0.95 to 0.96, and IRR=0.94, 95% CI 0.93 to 0.94, respectively), hurdles (IRR=0.97, 95% CI 0.96 to 97, and IRR=0.95, 95% CI 0.94 to 0.96, respectively) and throws (IRR=0.97, 95% CI 0.97 to 0.98). Conclusions Higher feels-like temperatures were associated with a decreased risk of time-loss and muscle injuries, particularly in sprints, hurdles and throws. Although the precise mechanism for lower injury rates with higher feels-like temperatures requires further investigation, adapting preparations such as warm-up or clothing to forecasted weather conditions may be of benefit.

国际户外运动锦标赛期间感觉温度与受伤风险之间的关联：一项对 29 579 名运动员在 10 届锦标赛期间开始的前瞻性队列研究


目的 分析用通用热气候指数 （UTCI） 测量的类似感觉的温度与国际田径锦标赛期间受伤率之间的关联。方法 在 2007 年至 2022 年的 10 届国际户外田径锦标赛期间，由医疗团队和当地组委会收集赛内损伤。UTCI 每小时从每届锦标赛期间观测到的大气条件的全球再分析中提取。我们进行了泊松回归，以发生率（每 1000 名运动员出发的受伤次数）作为结局，将 UTCI 作为预测变量，针对性别、所有和时间损失损伤、不同的受伤组织类型（即肌肉、肌腱、韧带、关节、骨骼和皮肤）和特定学科（即短跑、跨栏、跳跃、投掷、中距离、长距离、马拉松和竞走）。结果 29 579 名运动员首发共报告了 1203 例赛中损伤。对于所有赛中损伤 （即所有受伤组织类型和所有学科），较高的 UTCI 与较低的时间损失损伤发生率相关 （IRR=0.98,95% CI 0.97 至 0.98），但并非与所有损伤相关 （IRR=1.00,95% CI 1.00 至 1.01）。根据包括所有学科的损伤组织类型，较高的 UTCI 与所有 （IRR=0.97,95% CI 0.97 至 0.98） 和时间损失 （IRR=0.96,95% CI 0.96 至 0.96） 肌肉损伤的发生率较低相关。根据特定学科，较高的 UTCI 与短跑（分别为 IRR=0.95,95% CI 0.95 至 0.96 和 IRR=0.94,95% CI 0.93 至 0.94）、障碍（IRR=0.97,95% CI 0.96 至 97，IRR=0.95,95% CI 0.94 至 0.96）和投掷（IRR=0.97,95% CI 0.94 至 0.96）和投掷（IRR=0.97， 95% CI [0.97， 0.98]）。 结论 较高的感觉状温度与时间损失和肌肉损伤的风险降低相关，尤其是在冲刺、障碍和投掷中。尽管在较高感觉温度下降低受伤率的确切机制需要进一步研究，但根据预测的天气条件调整热身或服装等准备工作可能会有所帮助。数据可根据合理要求提供。气象数据来自 ERA5 HEAT（迪那不勒斯，2022 年），特别是 2024 年在 Navarro 和 Klöwer 举行的锦标赛。纳瓦罗，L和克洛沃，M（2024）。milankl/AthleticsChampionshipsHeat：BJSM 2024 出版物 （v2.0） 的气象数据和分析脚本。芝诺多。.可根据合理要求提供伤害数据。将根据具体情况考虑相关研究人员和实体的数据共享请求。有兴趣的人请联系通讯作者 Pascal Edouard （pascal.edouard@univ-st-etienne.fr）。
