摘要

目的:本研究旨在描述参加 2024 年 3 公里世界游泳大师公开水域游泳锦标赛的游泳运动员的核心体温(Tc)反应:在横断面观察研究设计中,游泳运动员(n = 48 [23 名男性,25 名女性])在比赛前 4 小时摄入遥测 Tc 药片。水温分别为 20.9 ℃(男性;平均湿球温度 25.9 ℃)和 20.5 ℃(女性;平均湿球温度 25.4 ℃)。线性混合模型确定了雄性和雌性在比赛开始温度、赛中平均温度和峰值温度方面的差异。随机系数模型确定了(1)性别、比赛时间、体重指数(BMI)、体质量变化或年龄与 Tc 峰值之间的关系;(2)性别、比赛时间、BMI、体质量变化或年龄与 Tc 低点之间的关系;(3)性别、Tc 峰值、BMI、体质量变化或年龄与比赛时间之间的关系;以及(4)性别、Tc 峰值、BMI、体质量变化或年龄与比赛名次之间的关系:赛中热卡平均值为 37.8 °C(36.1-38.8 °C);然而,个人热卡反应差异很大(-3.1 至 +2.7°C)。一名游泳运动员出现轻度体温过低(Tc ≤ 35.0 °C),5 名运动员体温超过 39.0 °C,这是导致热相关疾病的危险因素。男性和女性在比赛开始、平均和峰值 Tc 方面没有统计学差异(P ≥ .243)。较高的热卡峰值与较快的比赛时间(P = .05)、较高的比赛名次(P = .027)和较高的体重指数(P = .001)有关:结论:观察到的 Tc 反应差异很大(-3.1 至 +2.7 °C),这表明大规模公开水域游泳赛事的组织者应时刻做好准备,并提供设施来治疗游泳运动员在比赛期间出现的与冷/热相关的健康问题。

Core-Temperature Responses at the 3-km World Aquatics Open-Water Swimming Masters Championships in Doha 2024.

Purpose: This study aimed to characterize core-temperature (Tc) responses of swimmers competing at the 2024 3-km World Aquatics Masters Open Water Swimming Championships.

Methods: Within a cross-sectional observational study design, swimmers (n = 48 [23 male, 25 female]) ingested a telemetric Tc pill 4 hours before their race. Water temperatures were 20.9 °C (male; mean wet-bulb-globe temperature 25.9 °C) and 20.5 °C (female; mean wet-bulb-globe temperature: 25.4 °C). Linear mixed models determined differences between males and females for race-start, mean in-race, and peak Tc. Random coefficient models determined relationships between (1) sex, race time, body mass index (BMI), body-mass change or age, and Tc peak; (2) sex, race time, BMI, body-mass change or age, and Tc nadir; (3) sex, Tc peak, BMI, body-mass change or age, and race time, and (4) sex, Tc peak, BMI, body-mass change, or age and race ranking.

Results: The mean in-race Tc was 37.8 °C (36.1-38.8 °C); however, there were highly variable individual Tc responses (-3.1 to +2.7 °C). One swimmer experienced mild hypothermia (Tc ≤ 35.0 °C), and 5 exceeded 39.0 °C, a risk factor for heat-related illness. There were no statistical differences between males and females for race-start, mean, and peak Tc (P ≥ .243). Higher peak Tc was associated with faster race time (P = .05), higher race rank (P = .027), and higher BMI (P = .001).

Conclusions: Highly variable Tc responses (-3.1 to +2.7 °C) were observed, demonstrating that organizers of mass-participation open-water swimming events should always be prepared for, and provide facilities to treat, swimmers experiencing cold-/heat-related health incidents during competition.
