Lipid peroxidation processes as influenced by aerobic loads

Aim: to study lipid peroxidation products, levels of antioxidant activity in saliva of women aged 20-39 engaged in aerobics. In women engaged in aerobics for three years long-term adaptation to physical loads was accompanied with significant increase in antioxidant system - by 6-57 %, decrease in content of isopropanol-soluble molecular products of lipid peroxidation by 6-12 %, increase in concentration of primary heptane-soluble lipid peroxides by 17-21 %. Submaximal physical loads for 20-39-year-old women were associated with significant decrease in levels of heptane-soluble lipid peroxides and increase in levels of isopropanol-soluble lipid peroxides. The results have discovered features of how ‘lipid peroxidation - antioxidant protection’ system is adapted to moderate physical loads in 20-39-year-old women that provides better understanding of particular and general features of physiological and biological principles of adaptation to physical loads. Parameters of ‘lipid peroxidation - antioxidant protection’ in saliva may be used as an available and informative criterion in estimation of performed muscular work intensity.
