| Related to oxygen free radical theory has been research in the field of sports medicine is a hot issue. The so-called oxygen free radicals, that is, when the body for metabolism, they can take away an electronic oxygen, the oxygen atoms become free radicals. As human waste, free radicals can promote the occurrence of certain diseases and the aging body. Also known as superoxide dismutase SOD. Specificity of this enzyme can remove the body of harmful free radicals and free radical oxidation to remove certain components of the body caused by damage to the body. Prove that a large number of modern medical research, SOD is the body of one of the most important protective enzyme, both radiation damage, can effectively resist peroxide anion radical, anti-aging in order to regulate the body metabolism and improve the body's own immune function. However, is what kind of exercise intensity in the body after exercise will antioxidant capacity, but also to be further studied. Through this experiment, rats of different intensities of exercise training and psychological stress intervention to explore the different exercise and psychological stress on the body of rats SOD antioxidant capacity.Experimental use of swimming on body weight of 350g-400g of Wistar rats to moderate-intensity (training day 30min), high-intensity (training day 60min), high intensity and psychological stress (daily in containers for movement 60min after stimulation ) campaign training were killed after 8 weeks. From rat peritoneal blood, centrifuged extract serum, liver, kidney, heart tissue homogenate preparation, using colorimetry (kit) Determination of the serum and tissue samples of SOD.The results showed that: different exercise intensity and psychological stress on the ability of antioxidation in rats will produce different effects. Compared with the control group, moderate-intensity, high-intensity, high-intensity campaign intervention psychological stress increases the body's antioxidant capacity were improved; but in different parts of different levels of SOD. |
