Abstract

Background: Energy production is a necessary process to continue physical activities, and EXERCISE is associated with more oxygen consumption and increase of oxidative stress. what seems important is the numerical relationship between antioxidant and FREE RADICALS. Although the activity of some enzymes increases with physical activities, but it is possible that gene expression of this enzyme is not changed during EXERCISE.Objectives: The aim of the present study is to investigate the ANTIOXIDANT ENZYMEs gene expression and changes in malondialdehyde (MDA) and total antioxidant capacity (TAC) levels in men and women affected by a session of incremental EXERCISE and to carefully and numerically assess the relationship between MDA changes and gene expression and activity of ANTIOXIDANT ENZYMEs.Materials and Methods: 12 active men and 12 active women (21 - 24 years old) participated voluntarily in this study. Peripheral blood samples were taken from the subjects in three phases, before and after graduated EXERCISE test (GXT) and 3 hours later (recovery).Results: The gene expression of manganese superoxide dismutase (MnSOD) enzyme increased significantly in women in the recovery phase (P<0.05). Catalase gene expression significantly increased in men in both phases (immediately & recovery) (P<0.05).But the changes in active women were only significant immediately after the EXERCISE. TAC levels increased significantly in men in the recovery phase and in active women immediately after the EXERCISE (P<0.05). MDA activity also increased significantly in men in both phases (P<0.05). However, in women the increase was significant only in the recovery phase (P<0.05). There was a reverse relationship between changes in MnSO Dand copper- and zinc-containing superoxide dismutase (Cu/ZnSOD) levels and MD Ainmen (P<0.05). In active women there was also a significant relationship between changes in MD Aand gene expression of Cu/ZnSOD and TAC (P<0.05).Conclusions: The increase in FREE RADICALS during incremental EXERCISEs challenges gene expression and activity of ANTIOXIDANT ENZYMEs. However, despite the negative effects of FREE RADICALS, in women, activity and gene expression of ANTIOXIDANT ENZYMEs respond appropriately to FREE RADICALS.
