Thermoregulation in boys and men exercising at the same heat production per unit body mass

PurposeChild–adult thermoregulatory comparisons may be biased by differences in metabolic heat production (H˙p$$\dot{H}_{\text{p}}$$). We compared thermoregulatory responses of boys and men exercising at two intensities prescribed to elicit either a fixed H˙p$$\dot{H}_{\text{p}}$$ per unit body mass (BM) or a fixed absolute H˙p$$\dot{H}_{\text{p}}$$.MethodsTen boys (10–12 years) and 10 men (19–25 years) performed 4 × 20-min cycling at a fixed …
