The purpose of this study is to investigate the effect of wearing sweat suit on rectal temperature, oxygen uptake and sweating rate during ventilatory threshold exercise. 14 healthy students served as subjects in the experimental chamber which was controlled 22±1℃, 60±10%RH and no wind. The experimental clothes were Sweat Suit(SS) and General Suit(GS), SS was the product of R sports wear company which was consisted of long-sleeved jumper(100% polyester) and full length trousers(100% polyester) and GS were consisted of long sleeved shirt(100% cotton) and full length trousers(100% cotton). The subject were same socks and shoes in both experimental clothes SS and GS. The subject reported at the experimental chamber at the same time on each experimental day, exchanged their clothes to the experimental clothes SS or GS, wore all sensors for the physiological measurements and had a rest in a sitting posture about 10min. After rest, the subject carried out 20 min VT exercise on the treadmill and during the exercise rectal temperature, VO2, and evaporative weight loss were measured continuously and compared between two experimental clothes SS and GS.
The major findings were as follows;
Firstly, the increased in rectal temperature during 20min exercise was higher in experimental clothes SS than in GS.
Secondly, VO2 were a little bit higher SS and GS.
Thirdly, the evaporative weight loss(sweat rate) was greater in SS than GS.
These results indicate that the thermophysiological responses and sweating rate differs according to the wearing suit even though the subjects performed same exercise.
