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

Methods Subjects A total of 14 elite/preelite racewalking athletes participated in this study including 9 females (age

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

Despite this, early adaptations such as lowered core temperature ( T c ) and exercise heart rate (HRex) can be obtained in as little as a few days. 5 While prolonged HA protocols are understood to be the most effective in achieving the desired outcomes, team sport practitioners seeking heat

30°C to 35°C can increase acute repeated-sprint performance without deleterious heat stress. 10 This effect generally occurs if the core temperature (Tc) is kept below 38.5°C. However, it remains unclear how hypoxic exposure may affect these recommendations. The literature has independently
