초록
본 연구의 목적은 21% 농도의 산소와 비교하여 30%의 고농도 산소 흡입이 사이클 등속 운동 중에 심박동률(heart rate)과 혈중 산소 포화도(SPO2)에 미치는 영향을 분석하는 것이다. 21%와 30% 농도의 산소를 각각 8liter/min의 양으로 일정하게 공급할 수 있는 산소 공급 장치를 이용하였다. 신체 건강한 10명의 남자 대학생(25.2±2.2세)이 21%와 30%의 두 종류의 산소 농도를 대상으로 각각 두 번의 실험에 참여하였다. 실험은 안정(2분), 20±1km/h의 사이클 등속 운동(10분), 회복(6분)의 세 구간(총 18분)으로 구성되어 있고, 21% 또는 30%의 산소는 등속 운동과 회복 구간에만 공급되었다. 21%에 비해 30% 산소를 흡입했을 때 사이클 등속 운동과 회복 기간 중에 심박동률은 감소하였고, 혈중 산소 포화도는 차이가 없었다. 21%와 30% 두 그룹 사이에 동일한 운동 부하가 주어졌기 때문에 혈중 산소 포화도는 차이가 없는 것으로 판단되고, 30%의 고농도 산소 흡입으로 동일 운동 부하에 필요한 산소 요구량이 원활히 공급되고 있기 때문에 심박동률은 감소한 것으로 판단된다.
Abstract
The purpose of this study is to analyze the effects of the inhalation of 30% oxygen on heart rate and oxygen saturation (SPO2) during cycle isokinetic exercise, in comparison with the inhalation of 21% oxygen. This study used oxygen supply equipment that can supply each of 21% and 30% oxygen constantly at a rate of 8 liter/min. Ten healthy male college students (25.2±2.2 years) participated in the experiment twice, one for 21% oxygen and the other for 30% oxygen. Each experiment was composed of three sections (a total of 18 minutes), which were composure (2 minutes), cycle isokinetic exercise at a speed of 20±1km/h (10 minutes) and recovery (6 minutes). 21% or 30% oxygen was supplied only during the sections of isokinetic exercise and restoration. Heart rate during isokinetic exercise and recovery was lower with the inhalation of 30% oxygen than with that of 20% oxygen but no difference was observed in SPO2. SPO2 was not different possibly because the same work load was applied to the group of 21% oxygen and that of 30% oxygen. Heart rate was reduced with the inhalation of 30% oxygen possibly because a larger quantity of oxygen was supplied at the same work load.
