摘要

In order to elucidate the relationship between ROS homeostasis and physical training, the ROS levels of blood were measured before, during and after a certain physical challenge by the method of chemiluminescence. The intensity of physical challenge is designed to make volunteers reach 85% of maximum heartbeat and sustain till the subject willing to rest. The female volunteers were categorized into three groups. SED Group: as a sedentary subjects group (n=12), STT Group: short term exercise training subjects group (n=11), and LTT Group: long term exercise training group.
Our study's results show that the ROS turnovers of these two groups are quite different during physical challenge. The ROS level seems to be consistent in the group of regular exercise, but increasing in the group of seldom exercise during physical challenge. All volunteers were capable to neutralize ROS after a two-hour rest. In spite of insignificant change in some clinical parameters of blood, the activities of some scavenger enzymes such as SOD、catalase、GPx, seem to be decreased in the group of regular exercise. By comparing before with after 6-weeks-aerobic training, the group of seldom exercise showed decreased but quite similar patterns of the ROS level during physical challenge. Even after 6-weeks training, the ROS level measured before, during and after the physical challenge were still higher than the group of regular exercise.
