Ocena procesow oksydacyjno-redukcyjnych u mlodziezy z obnizona aktywnoscia ruchowa

The aim of the study was to assess oxidation-reduction processes in peripheral blood of adolescents with decreased motor activity. Motor activity was estimated in a group of subjects, aged 15 - 18 years. Exemption from physical education classes (PE) longer than 6 months was treated as low motor activity in the estimation of motor activity. Decreased motor activity /↓MA/ was observed in 27 cases, whereas normal motor activity was found in 42 subjects. The following evaluations were performed: lipid peroxidation process - malondialdehyde concentration in erythrocytes /MDAe/ and in plasma /MDAp/; antioxidative enzymatic system - superoxide dismutase activity /SOD/, catalase activity /CAT/ in erythrocytes. Very beneficial changes were observed after individual consideration of all exemptions from PE classes which, as it appeared, had not always been justified. Re-evaluation of physical activity demonstrated a marked increase of the group of physically active adolescents in the investigated population. Beneficial effect - 24,6% of girls and boys became physically active. The obtained results of investigations point to the weakening of antioxidative protection in adolescents with ↓MA as compared to adolescents with normal MA. Higher concentrations of MDAe and MDAp in adolescents with ↓MA prove intensified lipid peroxidation.
