Dynamics of antioxidant status indices in orienteering team members

Abstract

The present research is devoted to the study of the dynamics of antioxidant status indices in sportsmen going in for orienteering in the state of their maximum tiredness (right after competition) and after rest. The article presents the results of the research of malondialdehyde (MDA), catalase (C), superoxide dismutase (SOD) andglutathione-S-transferase (GST) content in venous blood erythrocytes. We revealed significant differences in the activity of enzymes of antioxidant defense system and malondialdehyde content depending on the previous level of physical activity. It was determined that restoration processes of an organism after the period of intensive physical activity were characterized by the decrease of MDA content and increase of the activity of enzymes of antioxidant defense system.
