[서론] 본 연구의 목적은 Åstrand 자전거 검사를 이용하여 신뢰성 있는 최대산소섭취량을 추정할 수 있는 최적운동부하를 선정하고, 성, 연령, 운동부하와 평균심박수를 이용한 에너지 소비량 추정 공식을 개발하는데 있다. [방법] 연구대상은 20대 남․녀 총 34명이며 Åstrand 자전거 검사를 이용한 최대하운동부하검사를 하였으며, 최초 운동부하는 남자, 여자 각각 선행연구에서 제시한 2개의 기존 강도(부하1, 부하2)와 기존 강도에서 50W씩 강도를 낮춘 강도(부하3, 부하4)로 총 4가지의 강도로 실시하였다. 예측된 최대산소섭취량과 Bruce protocol을 이용한 트레드밀 최대운동부하검사를 통해 얻어진 실측값을 비교하여 최정운동부하를 선정하였다. 성, 연령, 운동부하, 평균심박수를 이용한 에너지소비량 회귀식을 도출하기 위하여 다단계방식의 다중회귀분석(multiple regression analysis)을 실시하였다. [결과] 4가지 방법 중 가장 상관관계가 높은 것은 기존 방법 중 하나인 A2로 초기 강도를 남자는 150W(3.0kp), 여자는 125W(2.5kp)로 추정하는 방법이었다(r=0.692, p< 0.001). 기존의 부하를 변형한 새로운 방법 중에서 가장 적합한 것은 N2로 초기 강도를 남자는 100W(2.0kp), 여자는 75W(1.5kp)로 추정하는 방법이었지만(p< 0.001) 기존 방법인 A1과 A2에 비해 표준상관계수는 다소 낮게 나타났다(r=0.555). Åstrand 자전거 검사를 이용한, 연령, 운동부하, 평균심박수를 통한 에너지소비량 추정 결과 모델의 적합성은 F=10.117(p< 0.001), 결정계수 R2=58.3%로 나타났으며, 이에 따른 추정회귀식은 다음과 같다.

Abstract
[INTRODUCTION] The purpose of this study was to establish the optimal exercise load for developing a reliable prediction model of O2max from sex, age, exercise load, mean heart rate, and energy expenditure using Åstrand Bicycle test. [METHOD] The subjects (20‘s men and women, n=34) were entitled Åstrand bicycle test as submaximal exercise test. The test was initiated with the intensities which had been suggested by previous study (intensity 1 or A1 and intensity 2 or A2) and that was 50W-lower than those each(intensity 3 or N1, the intensity 4 or N2). The optimal level of exercise load was obtained from both predicted O2max and measured O2max using Bruce protocol stress test. Multiple regression analysis was carried out to derive a regression equation for energy consumption using gender, age, exercise, mean heart rate. [RESULTS] The highest correlation(r = 0.692, p<0.001) between the four methods was the one of conventional methods, A2 which initiated 150W(3.0kp) for men and 125W(2.5kp) for women. Between the new methods, N2 was found to be the most appropriate (p<0.001), N2 which initiated 100W(2.0kp) for men and 75W(1.5kp) for women, but it showed lower correlation (r=0.555) than conventional methods(A1 and A2). For the precited model to estimate energy consumption using age, exercise, mean heart rate during Åstrand bicycle test, the suitability F = 10.117 (p<0.001) and coefficient of determination R2= 58.3% were found. The estimated regression equation was O2max(ml/kg/min)=78.764+(-13.915×gender)+(-0.861×age)+(0.053×exercise) +(-0.074×mean heart). [CONCLUSION] A2 is the most appropriate method for Åstrand bicycle test. Although they showed similar level of suitability, N2 was more appropriate within the newly modified methods. In addition, the prediction for O2max with four variables appears to be suitable as the coefficient of determination(variance) was reasonable, i.e., R2 = 58.3%.
