title: [Effects of enriched oxygen on human free radical metabolism during exercise at 5 380 m plateau].
abstract: OBJECTIVE
  To study the effect of enriched oxygen on free radical metabolism at high altitude.
  
  
  METHODS
  SOD, GSH-Px and MDA were measured in 10 health young men after step in a room with or without oxygen enrichment at high altitude of 5 380 m.
  
  
  RESULTS
  After exercise in the oxygen-enriched room, SOD and GSH-Px increased significantly while MDA decreased notably (P<0.01) than those after exercise in the room without oxygen enrichment (P<0.05 or P<0.01).
  
  
  CONCLUSIONS
  Enriched oxygen can decrease damage from free radical at high altitude.
