We studied the effects of fabric moisture and water transport properties on temperature regulation in women during both 30 min exercise (78 W) and 30 min recovery periods at an ambient temperature of 16℃. We found the fall of rectal temperatures significantly smaller, but that of mean skin temperatures and that of temperatures of clothing microclimate measured between back skin surface and the garments significantly greater during 30 min recovery period in the subject having worn the cotton garment (C) having good fibre moisture absorbency than in the subject having worn the acryl garments (A) and the acryl ones with hydrophile properties (At), which have poor fibre moisture absorbency. Five out of seven subjects preferred C to A and At as comfortable garments during 30 min recovery period. The reason for such differences occurring was discussed in view of thermal physiology and the differences of fabric moisture and heat transport properties.
