이 연구는 유산소 운동 수행시 운동 환경이 인체에 미치는 영향을 알아보기 위해 임의적인 산소농도 23%산소농도와 실내 환 경농도인 19%산소농도로 조성하여 변화양상을 규명하여, 환경에 따른 인체에 미치는 영향을 제시하고자 한다. 연구의 대상은 대 학에 재학 중인 신체 건강한 남학생 16명을 대상으로 선정하여, 이들을 19% 산소농도에서의 환경과 23% 산소농도의 환경에서 60%VO2R 강도로 30분 운동수행을 실시하도록 하였으며, 혈액변인은 운동전, 운동직후, 회복후 5분간 측정을 하였고, 호흡 변인은 운동직후 측정을 하였다. 측정된 결과를 토대로 통계검정을 하여 나온 결과는 다음과 같다. 산소섭취량(VO2), 동맥혈 산소분압 (PaO2), 이산화탄소 생성량(VCO2), 환기량(VE), 그리고 동맥혈 이산화탄소분압(PaCO2)에서 19% 산소농도와 23%산소농도 집단간 모두에서 운동직후 유의한 차이가 나타났다(p<0.001)(p<0.05). 또한 ACTH, Cortisol 그리고 Lactic acid는 19% 산소농도집단과 23% 산소농도 집단간 운동직후, 회복기에서 통계적 유의한 차이가 나타났다. 그러나 Ammonia에서는 통계적인 유의한 차이가 나타나지 않았다. 이상의 결과를 종합해 보면 23% 산소농도에서는 산소섭취효율이 효율적이었으며, 스트레스가 저하되고 피로물질이 적게 쌓이며 지방연소와 에너지소비 측면에서도 효과적으로 나타났다. 따라서 건강 증진을 위한 유산소 운동 수행시 대기 산소농도를 유지시키는 것이 효과적인 운동방법이 될 것이다.

The purpose of this study was to examine the effects of exercise environment on body through aerobic exercise. For the purpose, oxygen concentration was voluntarily controled to 23% which was exercise environment in outdoor and to 19% which was exercise environment in indoor, and the process of physical change was observed, effect of Metabolic in environment. 16 subjects were selected who were in good health and university student. All subjects performed the exercise in voluntarily controled environment both in 19% and 23% oxygen concentration with 60%VO2R for 30 minutes. Blood variables were measured in three times: pre-exercise, post-exercise, and recovery. respiratory variables were measured in post-exercise. The main results of this study were as follow: There was significantly different in VO2, PaO2, VCO2, VE, PaCO2, at post-exercise and recovery time between 19% oxygen concetration group and 23%oxygen concetration group(p<0.001)(p<0.05). And then there were significantly different in ACTH, Cortisol and Lactic acid at post-exercise and recovery time between 19% oxygen concetration group and 23%oxygen concetration group. But there were no significant different in Ammonia. In conclusion, The oxygen uptake efficiency of 23% oxygen concentration was more efficient, decreases stress and fatigue substances accumulate less fat burning and was effective in terms of energy consumption. Therefore, when performing aerobic exercise for health promotion to keep the concentration of atmospheric oxygen that would be an effective way of exercise.
