최대하 운동시 온도변화에 따른 운동복 형태가 인체에 미치는 영향 = Effects of uniform style and temperature change on physiological responses during submaximal exercise

다국어 초록 (Multilingual Abstract)

This study is aimed at finding out the effect of environmental temperature and uniform style on physiological responses by analysing variations of human temperatures(rectal temperature, mean skin temperature), perspiration(total perspiration, partial perspiration), heart-rate, oxygen intake depending on variations of environmental temperatures(each 50% RH per 25℃, 30℃, 35℃) and uniform styles(long sleeve, half-sleeve) during the long time(40min) sub-maximal exercise(50% V02max)
This experiment was performed on the subjects of 6 male university students by using the bicycle ergometer.
The change of human temperature and heart rata were measured by the interval of 10 minutes during exercise.
The total perspiration was measured by the difference of weight before/ after exercise, and the local perspiration by the difference of its filter's weight before / after exercise after a filter of 2.5cm diameter was attached on the back and the femoral.
The oxygen intake was measured by collecting aerobic gas for final one minute by the interval of 10 minutes during exercise, and then analysing gas.
The experimental results are as follows.
1. The skin temperature increased in proportion to the environmental temperature, and the rectal temperature continuously increased from at the beginning of exercise, and no meaningful difference was by uniform styles.
2. Perspiration increased in proportion to the environmental temperature, no meaningful difference was by uniform style, and there was more perspiration in the back than in the femoral.
3. Heart rate fast increased after exercise, and then gradually increased from after 10 minutes, increased in proportion to the environmental temperature, and no meaningful difference was by uniform styles.
4. The volume of oxygen intake fast increased early exercise, and then gradually increased up to 30 minutes, and was prone to keep in the constant level or decrease, and no meaningful difference was by environmental temperatures or uniform styles.
There generally was the meaningful difference by environmental temperatures under most conditions by the results above, but no meaningful difference was by uniform styles. Considering this results, under the intensity of exercise (50% V02max), the variation of environmental temperatures(25℃,30℃,35℃) influenced on physiological responses, whereas the variation of uniform styles did not influence on physiological responses.
