The study was intended to examine the effect of thermoregulation on cardiorespiratory performance in view of the function of thermoregulation, and examined 10 students attending physical education departments in Jeonju University. I divided the subjects into the first group(the static rest-group) and the second group(the cool immersion rest-group)and checked them at weekly intervals. As a result, the variables such as exercise endurance time, heart rate, tympanic membrance temperature and blood lactic acid have changed as follows: 1. Maximal exercise stress test of those who experienced a static-rest has longer duration, about 15.96% up than maximal exercise stress test of those who experienced a cool immersion rest-group in exercise endurance time. It shows a significant difference statistically(P<.05). 2. In regard with the change of the tympanic membrance temperature, cool immersion rest-group has a result of low temperature-rising rate than static rest-group. It shows a significant difference statistically(P<.O5). 3. In regard with the change of the heart rate, the static rest-group than the cool immersion rest-group has the result of a larger difference in the rise of the heart rate, while in the recovery rate of the heart rate the cool immersion rest group than the static rest group has the result of a higher figure. It shows a significant difference statistically(P<.05). 4. In regard with the change of the blood lactic acid, the cool immersion rest-group indicates lower figures of the result in all of each of measures' time. It shows a significant difference statistically.(P.05). The conclusion comes from the above results. Summarizing the results the conclusion is that while taking a rest in an environment with high temperature, coming back to normal temperature from high temperature after exercises in a cool immersion rest than in a static rest, results in better effects that help to recover exercise endurance time, heart rate and blood lactic acid through control of the increased tympanic membrance temperature, as well as the primary medium of a hypothalamic and core temperature. Consequently, a cool immersion rest showed more positively effects on cardiorespiratory performance than a static rest does.
