The main purpose of the study is to determine the influence of exercise intensity on the level of tissue damage, and mechanism of tissue damage based on the free radicals concept. The subject of this study were 30 healty males, untrained and ages between 19 and 22 years, randomly assigned to anaerobic exercise and aerobic exercise. Level of tissue damage was measured by the activity of plasma lactate dehydrogenase (LDH) and creatine phosphokinase (CPK), plasma lipid preroxidation product was measured by the level of plasma malodialdehyde (MDA), and activity of antioxidant enzymes measured superoxide dismutase (SOD) and catalase (CAT) in erythrocytes before and after exercises. The results showed an increase of lipid peroxidation product the level of tissue damage, and the increase of antioxidant enzymes activity were significantly higher in anaerobic exercise compared to aerobic exercise subjetcs. The level of lipid peroxidation production was influenced by the level of lactic acid and the level of antioxidant enzymes (p < 0.05). This study proved that the free radicals concept had an influence on the mechanism of tissue damage in physical exercise, The risk of tissue damage was smaller in aerobic exercise than in anaerobic exercise subjects.
