Original Article : Effects of endurance exercise training on antioxidants activities in rats
Abstract
Prolonged endurance exercise training is known to lowering oxidative damage during exercise. Therefore, we examined the effects of endurance exercise training on antioxidants enzymes activities in rats. Rats were trained on the treadmill with 1 % incline, 28m/min, 1h/day, and 5d/wk for 6 wks in the trained group (TR). Sedentary group did not perform the endurance exercise training (NT). They were decapitated at before and after exercise. Then, liver, heart, soleus muscle, gastrocnemius red and white muscle samples were collected for malondialdehyde (MDA) and superoxide dismutase (SOD) analysis. Students t-test was performed as the statistical analysis. Endurance exercise training has significantly reduced MDA concentrations in liver, heart, and gastrocnemius muscle. In addition, SOD concentration was significantly increased in liver, heart, soleus muscle, gastrocnemius red and white muscle. These results suggest that endurance exercise training reduced the risk of lipid peroxidation during exercise in rats.
