Influence of exercise-heat acclimation protocol characteristics on adaptation kinetics: A systematic review with meta-analysis

Introduction: Exercise-based heat acclimation (HA: repeated bouts of exercise in artificially hot environments), induces adaptations that attenuate physiological strain during exercise in the heat. Several factors influence the kinetics of adaptation (i.e. magnitude and time course), including the environmental characteristics, number and duration of exposures, and exercise intensity. However, the extent to which these factors influence the adaptive response is not fully understood. The aim of this review was to systematically assess the influence of HA protocol characteristics (ambient temperature: Ta, partial pressure of water vapour in air: Pa, number of exposures and exposure duration), on end-exercise core temperature (Tc) and heart rate (HR), and whole-body sweat rate (WBSR).
