Individual characteristics associated with the magnitude of heat acclimation adaptations.

ABSTRACT:

Purpose

The magnitude of heat acclimation (HA) adaptations varies largely among individuals, but it remains unclear what factors influence this variability. This study compared individual characteristics related to fitness status and body dimensions of low-, medium-, and high responders to HA.

Methods

Twenty-four participants (9 female, 15 male; maximum oxygen uptake [[Formula: see text]O_2peak,kg] 52 ± 9 mL kg^-1 min^-1) completed 10 daily controlled-hyperthermia HA sessions. Adaptations were evaluated by heat stress tests (HST; 35 min cycling 1.5 W  kg^-1; 33 °C, 65% relative humidity) pre- and post-HA. Low-, medium-, and high responder groups were determined based on tertiles (n = 8) of individual adaptations for resting rectal temp
