스쿠버 운동 시 서로 다른 호흡 산소 분압 차이가 헤마토크리트 변화에 미치는 영향

초록

This research examined the effect of oxygen partial pressure o nhematocrit changes in SCUBA diving exercise Ten male university students divers performed cycle execrise on immersion at 5 m and a pedaling o f stationary bike for 20 min. Blood was drown from ante cubitale vin at resting, immediately after exercise, and 30min after that. No significant differences was found in circulating red blood ecll, mean corpuscular volume and mean co-r puscular hemoglobin concentration among the three experimental conditions. There were significant differences in hematocrit levels, hemoglobin, and mean corpuscular hemoglobin among the three different experimental conditions. In conclusion, The hyperbaric hyperoxia condition during cyclee xercise on immersion was found to effec t the hematocrit and hemoglobin. The phenomenon maybe related to hyperbaric hyperoxia condition. The hyperbaric hyperoxia condition can lead to improve diffusive oxyegn transport as indicated by the improvement of local tissue oxygen partial pressure in the absence of a snigificant change in total oxygen delivery capacity . Our results indicate that exercise in the hyperbaric hyperoxiac ondition like scuba diving might be play a rol e in the change the blood profile and hemodynamics.
