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.

Heat Preparation and Knowledge at the World Athletics Race Walking Team Championships Muscat 2022.

Purpose: To assess elite racewalkers' preparation strategies, knowledge, and general practices for competition in the heat and their health status during the World Athletics Race Walking Teams Championships (WRW) Muscat 2022.

Methods: Sixty-six elite racewalkers (male: n = 42; mean age = 25.8 y) completed an online survey prior to WRW Muscat 2022.

Association between thermal responses, medical events, performance, heat acclimation and health status in male and female elite athletes during the 2019 Doha World Athletics Championships.

Purpose: To determine associations between thermal responses, medical events, performance, heat acclimation and health status during a World Athletics Championships in hot-humid conditions.

Methods: From 305 marathon and race-walk starters, 83 completed a preparticipation questionnaire on health and acclimation. Core (T; ingestible pill) and skin (T; thermal camera) temperatures were measured in-competition in 56 and 107 athletes, respectively.

Hydration and cooling in elite athletes: relationship with performance, body mass loss and body temperatures during the Doha 2019 IAAF World Athletics Championships.

Purpose: To characterise hydration, cooling, body mass loss, and core (T) and skin (T) temperatures during World Athletics Championships in hot-humid conditions.

Methods: Marathon and race-walk (20 km and 50 km) athletes (n=83, 36 women) completed a pre-race questionnaire. Pre-race and post-race body weight (n=74), T (n=56) and T (n=49; thermography) were measured.

Daily running exercise may induce incomplete energy intake compensation: a 7-day crossover trial.

Understanding daily exercise effects on energy balance is important. This study examined the effects of 7 days of imposed exercise (EX) and no exercise (N-EX) on free-living energy intake (EI) and physical activity energy expenditure (PAEE) in 9 men. Free-living EI was higher in EX compared with N-EX.
