Abstract: Regional differences in thermal sensation to a hot or cold stimulus are often limited to male participants, in a rested state and cover minimal locations. Therefore, magnitude sensation to both a hot and cold stimulus were investigated during rest and exercise in 8 females (age: 20.4±1.4years, mass: 61.7±4.0kg, height: 166.9±5.4cm, VO<inf>2max</inf>: 36.8±4.5ml·kg<sup>-1</sup>·min<sup>-1</sup>). Using a repeated measures cross over design, participants rested in a stable environment (22.3±0.9°C, 37.7±5.5% RH) whilst a thermal probe (25cm<sup>2</sup>), set at either 40°C or 20°C, was applied in a balanced order to 29 locations across the body. Participants reported their thermal sensation after 10s of application. Following this, participants cycled at 50% VO<inf>2max</inf> for 20min and then 30% VO<inf>2max</inf> whilst the sensitivity test was repeated. Females experienced significantly stronger magnitude sensations to the cold than the hot stimulus (5.5±1.7 and 4.3±1.3, p<0.05, respectively). A significant effect of location was found during the cold stimulation (p<0.05). Thermal sensation was greatest at the head then the torso and declined towards the extremities. No significant effect of location was found in response to the hot stimulation and the pattern across the body was more homogenous. In comparison to rest, exercise caused a significant overall reduction in thermal sensation (5.2±1.5 and 4.6±1.7, respectively, p<0.05). Body maps were produced for both stimuli during rest and exercise, which highlight sensitive areas across the body.
