Estimating Resting Core Temperature Using Heart Rate

David P. Looney, Mark J. Buller, Andrei V. Gribok, Jayme L. Leger, Adam W. Potter, William V. Rumpler, William J. Tharion, Alexander P. Welles, Karl E. Friedl, and Reed W. Hoyt

In healthcare and in general living conditions body core temperature (CT) is considered one of the most informative indicators of thermal stress ( Montain, Sawka, Cadarette, Quigley, & McKay, 1994 ; Sawka et al., 2001 ), a key indicator in thermal comfort ( Gagge et al., 1967 ), and has a wide

Core Temperature Responses to Elite Racewalking Competition

Christopher John Stevens, Megan L. Ross, Julien D. Périard, Brent S. Vallance, and Louise M. Burke

investigation were to present a brief summary of the core temperature responses of elite race walkers during competition, as well as the use of cooling strategies, and symptoms of heat illness. Methods Subjects A total of 14 elite/preelite racewalking athletes participated in this study including 9 females (age

Thermal Sensation After the 10-km Open-Water Swimming in Cool Water Depends on the Skin’s Thermal Sensitivity Rather Than Core Temperature

Tomomi Fujimoto, Yuiko Matsuura, Yasuhiro Baba, and Reira Hara

maintenance of body temperature is important for safety and performance improvement. Core temperature ( T core ) is determined by the balance between heat production and heat loss, specifically during exercise in water, the former being exercise-related heat production and shivering and so on, 2 and the

Limiting the Rise in Core Temperature During a Rugby Sevens Warm-Up With an Ice Vest

Lee Taylor, Christopher J. Stevens, Heidi R. Thornton, Nick Poulos, and Bryna C.R. Chrismas

During World Rugby Sevens Series (WRSS) match play in temperate (wet bulb globe temperature range: 14–19.2°C) and warm (wet bulb globe temperature range: 25–27°C) conditions, peak player core temperatures ( T c ) of 39.6°C and 39.9°C, respectively, have been observed. 1 When T c is >39°C

attributed the enhanced recovery of maximal voluntary contraction force to faster return of central activation, which is the result of larger CWI-induced reductions in core temperature ( T c ). 3 With hyperthermia-mediated fatigue being a key fatiguing factor for many forms of exercise, 1 a greater

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

Chris J. Esh, Valentin Dablainville, Feriel Dalansi, Sayyam Kathuria, and Marco Cardinale

the thermal conductivity of water is ∼25 times that of air and submersion in water compromises thermoregulation, 1 , 3 athletes participating in OWS are likely to experience large and potentially accelerated increases/decreases in core temperature (Tc) compared with land-based sport. 3 This poses a

production combined with environmental heat and humidity challenges the body’s heat dissipation mechanisms. In addition, in summer months, heat dissipation during the swim phase may be affected by the warm water temperature (>29 °C) ( 11 ), which may lead to dangerous elevations in core temperature ( T c
