“…These findings are particularly relevant considering the accelerated global warming in recent decades, the increased incidence of heat waves (Dosio et al, 2018;Kenney et al, 2022), and several sports competitions held in hot and humid environments (Mündel, 2020).…”

“…However, their predictive power was less robust than the analysis including non‐practical variables (i.e., T core ‐to‐ T skin difference and initial T core ). These findings are particularly relevant considering the accelerated global warming in recent decades, the increased incidence of heat waves (Dosio et al., 2018 ; Kenney et al., 2022 ), and several sports competitions held in hot and humid environments (Mündel, 2020 ).…”

“…Endurance running competitions are popular sporting events with increasing numbers of participants (Cushman et al., 2014 ; El Helou et al., 2012 ; Noakes, 2003 ). In these competitions, athletes experience significant thermoregulatory strain (Racinais et al., 2019 ) because they exercise at high intensities (associated with fast rates of metabolic heat production) for prolonged periods, often under environmental heat stress (Mündel, 2020 ; Vihma, 2010 ). Thus, under conditions of exercise‐heat stress, measuring body core temperature ( T core ) is paramount to determining the thermoregulatory strain of athletes (Eggenberger et al., 2018 ).…”

Measurement of body core temperature (T core ) is paramount to determining the thermoregulatory strain of athletes. However, standard measurement procedures of T core are not practical for extended use outside the laboratory environment. Therefore, determining the factors that predict T core during a self-paced run is crucial for creating more effective strategies to minimize the heat-induced impairment of endurance performance and reduce the occurrence of exertional heatstroke. The aim of this study was to identify the factors predicting T core values attained at the end of a 10 km time trial (end-T core ) under environmental heat stress. Initially, we extracted data obtained from 75 recordings of recreationally trained men and women. Next, we ran hierarchical multiple linear regression analyses to understand the predictive power of the following variables: wet-bulb globe temperature, average running speed, initial T core , body mass, differences between T core and skin temperature (T skin ), sweat rate, maximal oxygen uptake, heart rate and change in body mass. Our data indicated that T core increased continuously during exercise, attaining 39.6 ± 0.5 • C (mean ± SD) after 53.9 ± 7.5 min of treadmill running. This end-T core value was primarily predicted by heart rate, sweat rate, differences between T core and T skin , wet-bulb globe temperature, initial T core , running speed and maximal oxygen uptake, in this order of importance (β power values corresponded to 0.462, −0.395, 0.393, 0.327, 0.277, 0.244 and 0.228, respectively).In conclusion, several factors predict T core in athletes subjected to self-paced running under environmental heat stress. Moreover, considering the conditions investigated, heart rate and sweat rate, two practical (non-invasive) variables, have the highest predictive power.
