高溫環境中最大衰竭運動之溫度調節現象探討

The Investigatin of Thermal Regulation during Maximal Exercise in Hot and Humid Environment

摘要


The purpose of this study was to compare the differences between hot-accommodated athletes (HA) and non-athletes (NA) on maximal exercise of lower extremities in hot and humid environment (35℃, 60% RH, wind speed: 0.8-1m/sec). The subjects, 5 male cyclists (experimental group-age 23.2±10.62 Y/O) and 5 healthy male (control gropuage25±2.12 Y/O), accetoed the progressive electrical bicycle test to be exhausted in hor and humid environment. During the testing, we recorded the values of(1)central temperature(CT); (2)skin temperature (ST) and nean skin temperature(MST); (3) skin blood flow(SB); (4)heart rate(HR)and(5)oxygen consumption(VO2). Before and after testing, we weighted the weight to understand the lost volume of water. The results were: (1) the elevation of CT and MST accompanied the increasing of exercise intensity. Between the experimental and control groups, CT had significant difference (P<.001), but there was no significant difference in BT. (2) the skin temperature of selected parts was elevated when the exercise intensity increased. Both the experimental and control groups had the same tendency. (3) the skin bolld flow was changed when the exercise intensity increased. No matter the changing ratio of SB on lower extremities or upper extremities, both groups had the same tendency.(4)during the same absolute exercise intensity, the HR and VO2 of experimental group were less than control group's, but there was no significant difference(P>.05). (5) during the maximal exercise, the VO2 of control group was less than experimental group's (P<.001). The HRmax had the same tendency, but there was no singificant difference. (6)the loss of weight after exercise was no significant difference between these two groups(P>.05). (7) the performance between both groups had significant difference(P<.01). We could find that experimental group had better physiological function and sports performance than control group.
