호흡가스 분석시스템의 신뢰성과 타당성의 정확한 평가를 위해서 동일한 목적을 가진 분석 기기이지만 분석방법이 다른 기기에서 분석된 자료들이 어느 정도 일치성이 있는지를 연구해 가스분석기의 타당성과 신뢰도를 검정하여 좀더 정확한 분석의 지표를 마련하고자 안정 시 결과와 트레드밀 2.0, 3.0, 4.0mph에서 호흡가스 결과의 타당도 및 검사-재검사 신뢰도를 조사하기위해 Y대학교에 제학중인 남자 15명을 대상으로 측정한 자료로 ...
호흡가스 분석시스템의 신뢰성과 타당성의 정확한 평가를 위해서 동일한 목적을 가진 분석 기기이지만 분석방법이 다른 기기에서 분석된 자료들이 어느 정도 일치성이 있는지를 연구해 가스분석기의 타당성과 신뢰도를 검정하여 좀더 정확한 분석의 지표를 마련하고자 안정 시 결과와 트레드밀 2.0, 3.0, 4.0mph에서 호흡가스 결과의 타당도 및 검사-재검사 신뢰도를 조사하기위해 Y대학교에 제학중인 남자 15명을 대상으로 측정한 자료로 대응표본 t-test를 실시한 결과 다음과 같은 결론을 얻었다. 첫째, 기기간의 타당도는 측정 및 판단 가능한 변동계수(RV)가 5%보다 낮았다. 둘째, 기기간의 타당도 차이는 운동 강도가 증가할수록 낮은 결과를 나타내었다. 셋째, 안정 시 폐쇄형인 breath by breath system기기가 개방형인 mixing chamber system기기에 비하여 낮은 신뢰도를 나타내었다. 2.0mph의 결과는 개방형인 mixing chamber system기기에 비하여 폐쇄형인 breath by breath system기기가 높은 신뢰도를 나타내었다. 넷째. 강도별 검사-재검사 신뢰도는 운동 강도가 증가 할수록 낮은 설명력을 나타내었다.

Respiratory gas analysis has been acknowledged as the most suitable factor to determine the intensity of exercise when exercise and rest metabolic rate is prescribed. However it is hard to be applied to the field due to the difficulty of measurement. Gas analysis is often utilized instead in pretilinealy proportional to energy expenditure and provides information about the heart. But heart rate and energy expenditure are easily affected by various factors such as temperature, humidity, the rate of activity of muscle utilization, psychological variables, weight and physical strength. Therefore, it is thought that the relationship between mixing chamber system and breath by breath system for energy expenditure observed by a gradual multi-step exercise load test may be changes are actually found, relation between mixing chamber system and breath by breath system may not be applicable to continuous exercise. In the experiment, 15 male in university were tested by the graded exercise test, and an equation of regression to output for each student were derived from her gas analysis as an independent variable and energy expenditure as a dependent variable. The following are results of these experiments. 1. At the intensity of staffs working, validity of mixing chamber system and breath by breath system were higher correlations in gas exchange. 2. At the intensity of 2.0mph exercise, validity of mixing chamber system and breath by breath system were lower correlations in gas exchange. 3. At the intensity of 3.0mph exercise, validity of mixing chamber system and breath by breath system were lower correlations in gas exchange. 4. At the intensity of 4.0mph exercise, validity of mixing chamber system and breath by breath system were lower correlations in gas exchange.
