Abstract
We studied the effects of season, wearing of garments with long-sleeves and clothing wettedness on temperatures of core, skin and clothing microclimate in sedentary and walking women at an ambient temperature of 28 °C and a relative humidity of 50 %. Our major findings are sum.marized as follows : 1) Mean skin temperature and clothing microclimate temperature were explicitly lower at end of November than at middle of September although the subject was exposed to same ambient temperature and wore same garments of either semi-nude or T-shirted training wear with long-sleeves. 2) Enlargement of body surface area covered by clothes due to wearing of T-shirted training wear induced increase of mean skin temperature and of clothing microclimate temperature, accompanying gradual decrease of 0.1-0.2 °C for 30 min in rectal temperature of the sedentary subject. 3) Wearing of wetted T-shirted training wear induced rapid decrease of mean skin temperature and made shorter the time for rectal temperature to begin to increase after beginning of walking on a level treadmill at a speed of 4 km/hr, compared with cases in regular T-shirted training wear. We discussed these phenomena in terms of thermal physiology.
