    The purpose of this study was to investigate the effects of the existence of silt ventilation system on physiological responses and subjective sensation. We measured rectal temperature, local skin temperature, blood pressure, heart rate, energy metabolism, body weight loss, clothing climate and subjective sensation during 70 minute, 50 min exercise period and 20 min rest period. The five women subjects randomly wore sportswear without slit ventilation system(NS sportswear) and sportswear with slit ventilation system(S sportswear) under environmental condition of 25±1℃, 50±5%RH, 10cm/sec. The results of this study are as follows; 1. Core temperature which was measured in rectum membrane began to rise rapidly in the period of exercise, and began to drop in the rest period with significant lower level in 'NS sportswear' than in 'S sportswear'. With correlation to the homeostasis of core temperature, we could find out that the 'S sportswear' was physiologically more effective comparing to 'NS sportswear'. 2. The skin temperature was generally lower in 'S sportswear' than 'NS sportswear'. Forearm and thigh skin temperatures indicated that 'S sportswear' with slit ventilation system has advantage in exercise. Bellow effect which makes an air current between the skin and the clothing let the skin temperature down with exercise. 3. Blood pressure rises with exercise which requires much more blood conveyance. Systolic pressure and diastolic pressure were significantly lower in 'S sportswear', especially the period of exercise. It has shown that 'S sportswear' lightened the load of heart and had advantage in physiological function. 4. The heart rate was lower in 'S sportswear' than in 'NS sportswear'. The heart rate means the amount of work accomplished by heart that satisfies increased requirement from body. It has shown that the 'S sportswear' reduces the load of body during exercise. 5. The energy metabolism supplies the energy for the growth of body, the maintenance of an organism, the operation of muscles. In our research, energy metabolism was lower in 'S sportswear'. With slit ventilation system, energy metabolism was reduced in exercise period. It has shown that the wearing of 'S sportswear' is more effective at the time of body movement. 6. The sweat rate was lower in 'S sportswear' than in 'NS sportswear'. It showed that the skin temperature and the rectal temperature were lower in 'S sportswear' than in 'NS sportswear' due to the slit ventilation system. The ventilation of 'S sportswear' was better than that of 'NS sportswear,' so it didn't need to control the skin temperature through the sweat in 'S sportswear'. In addition the amount of discharged moisture in 'S sportswear' was more than 'NS sportswear', 'S sportswear' was better during exercise. 7. Clothing microclimate temperature shown in the forearm was lower in 'S sportswear' than in 'NS sportswear', affecting by the silt ventilation system. On the other hand, clothing microclimate in humidity shown in forearm was higher in 'S sportswear' than in 'NS sportswear', due to the increase of air inflow under the environmental condition of 50±5%RH. 8. In subjective ratings, subjects felt more hot, more comfortable and more wet in condition of 'S sportswear'. It could be regarded that the wearing comfort is better in 'S sportswear' than 'NS sportswear', the 'S sportswear' is more effective to maintain the homeostasis at the time of exercise. From this investigation on slit ventilation system, it could be concluded that the ventilation system as the part of the functional sports wear is advantageous to physiological responses and improvement of record, and it can be applied to other fields as well as sportswear. Based on the result of this study, the following study could be investigated the application of the slit ventilation system with a point of design.
