This study investigated the resting levels of malondialdehyde plus 4-hydroxy 2-(E)-nonenal (MDA+4-HNE) in plasma, erythrocyte superoxide dimutase (SOD) and glutathione (GSH) in 12 long-distance runners (LR), 12 weight lifters (WL), and 12 age match sedentary nonathletes (SN). The subjects were asked to maintain the lifestyle and original training (Monday to Friday) and were requested not to take any medicines and supplementation two weeks ago before sampling. No significant differences were found in MDA+4-HNE levels among three groups. The LR group had lower erythrocyte SOD activities than SN group (p <0.05). Additionally, the erythrocyte GSH concentrations in WL group was significantly lower than LR and SN groups (p <0.05). The results indicated that the adaptation and changes in resting antioxidant status would be different due to various exercise training modes. Furthermore, athletes should take the antioxidant supplementation appropriately to overcome the high oxidative stress cause by heavy training.
