title: Effects of inhalation of oxygen on free radical metabolism and oxidative, antioxidative capabilities of the erythrocyte after intensive exercise.
abstract: Two groups, each containing 10 young healthy male students, participated in the study. One group breathed 70% O2 after exercise (70% O2 group) while the other group breathed normal air (Normal air group) after exercise. The results of the study show the following: (1) in both groups, the Monodehydyoxygenbate (MDA) in erythrocyte (RBC) and serum, and superoxide dismutase (SOD) and glutathione Peroxidas (GSH-px) in serum were significantly higher immediately after exercise than at rest; (2) the MDA in RBC and serum were significantly higher in the Normal air group than in the 70% O2 group for 30 minutes after exercise; and (3) the SOD in serum and GSH-px in blood and serum were significantly higher in the 70% O2 group than in the Normal air group for 30 minutes after exercise. We suggest that the effects of inhaling 70% O2 could prevent fatigue from antagonizing free radicals damage, hastening removal of free radicals, which would facilitate recovery from fatigue.
