The purpose of this study was to investigate about effect of Graded Exercise Test(GXT) on respiratory gas variables in acute normobaric hypoxic chamber. Further more, we tried to secure a data for development of a new LH-TL training medel. The subjects of this study were sixteen male in university tennis players. We observed differences in respiratory gas variables between sea level and hypoxia(2,200m; 16.2% O2) during maximal exercise test. All observed respiratory gas variables were expressed by mean and standard deviation and were analyzed by independent t-test to verify between groups differences. The results are as follows. There were significant reduction(P<.01, P<.05)) in exercise duration time and VO2max at normobaric hypoxia maximal exercise test. But, there were no significant differences in maximal breathing capacity(VE) and maximal heart rate(HRmax) between sea level and acute hypoxia condition. Therefore, we found that training exercise method in normobaric hypocia has the possibility to improve exercise performace. We put forward the several suggestions that later study will have to approach with more detailed and accurate method and try to find the causality between hypcoxia condition and decrement of SaO2, heart rate and gas exchange in pulmonary alveolus.

현대사회에 있어서 신체활동 연구의 주요 탐구과제는 ‘신체활동을 통한 교육’으로부터 ‘인간의 기본적인 움직임’을 목표로 하는 스포츠적인 움직임을 중심으로 한 생명 활동의 개념으로 급속히 변화되고 있는 추세이다. 이러한 환경변화에 대응하기 위하여 본학회는 ‘체육’적인 요소에서 ‘스포츠’적인 요소를 중심으로 한 학문적 정체성을 견고히 하고, 정기적인 학술지 발간과 학술활동을 통해 한국스포츠츠 문화의 발전과 학문적인 발전에 기여하는데 그 목적이 있다.
