Cooling Different Body Surfaces During Upper and Lower Body Exercise,

摘要

The effect of varying the body surface area being cooled by a liquid microclimate system was evaluated during exercise heat-stress conditions. Six male subjects performed a total of six exercise tests in a hot environment while dressed in clothing having low moisture permeability and high insulation. Each subject completed two upper body exercise 1) with only the torso surface (T) cooled; and 2) with the surfaces of the torso and upper arms (TA) cooled. Each subject also completed four lower body exercise with torso, upper arm, and thigh surface (TAT0 cooled with TAT cooled. These data indicate that cooling arms during upper body exercise provides no thermoregulatory advantage, although cooling the thigh surfaces during lower body exercise does provide an advantage.
