Before in the water, the rectal temperature was 37.9 degree C and after the test, the rectal temperature was 36.8 degree C. The difference of rectal temperature between the two phases was 1.1 degree C. The baseline of skin temperature was 34.4 degree C and the final skin temperature was 28.3 degree C. The difference of skin temperature was 6.1 degree C. The baseline of body temperature was 36.9 degree C and the final body temperature was 32.5 degree C. The gradient of temperature was 4.4degree C. The higher the gradients of temperature between body temperature and skin temperature, the more heat dissipation from body to skin. There was a difference between baseline and final stage on VO2, rectal temperature, skin temperature, and body temperature. However, there was no difference between baseline and final stage in heart rate. After 10 minutes exercise, the hemoglobin and hematocrit increased, however, the other variables, such as plasma volume percentage, cell volume percentage and blood volume percentage, decreased. In 20 minutes, hemoglobin decreased but hematocrit decreased. The others, for example, plasma volume percentage, cell volume percentage and blood volume percentage, decreased. Thirty minutes later, hemoglobin increased but hematocrit decreased. The other variables of blood were in a constant. After 40 minutes exercise, hemoglobin still increased, and the others were the same as in 30 minutes situations. According to the results of data, in cold water, not only did the body maintain the body temperature in a steady state, but also dissipated heat of metabolism from body to skin.
