The purpose of this study was to examine whether or not heat and moisture transport properties of fabrics correspond to thermo- regulatory responses during exercise in men wearing suits made of fabrics. Four kinds of fabrics (cotton (C), cotton/polyester (CP), wool (W), rubberized fabric (R)) were chosen and measured their properties. The air permeability, heat conductance and thermal insulation were affected by the moisture content in the fabrics and the extent was different between each fabric.
　Experimental suits with similar thermal resistance of clothing were made by using the fabrics mentioned above. Four men wearing each of them ran on a treadmill at 3 different intensities. Significant differences were observed for the local sweating rate and skin temperature (R >C CP >W), although the extent was different by the exercise intensity. Those differences may be the result of the air permeability of the fabrics.
