-연구배경 심폐지구력은 운동 처방을 할 때 매우 중요한 요소로서 이의 평가를 위해 현재 최대 또는 최대하 운동부하 검사를 이 용하고 있다. 그러나 일정한 장비와 시간 그리고 노력이 요구되는 운동부하 검사를 피검자 모두에게 시행하기가 용이하지 않아 다른 간편한 측정법의 도입이 요구되는 실정이다 . 본 연구는 젊은 성인 남자를 대상으로 트레드밀 검사를 이용한 최대 운동부하 검사에서 실측한 최대 산소섭취량으로 운동부하 없이 안정시 측정하는 Polar??Fitnes Test로 추정한 최대 산소섭취량을 비교하여 이의 타당도를 평가하고자 하며 이의 신뢰도도 평가하고자 한다 . 또한 최대하 운동부하를 이용하는 전자식 에르고미터 검사의 타당도도 아울러 평가하고자 한다 .방 법 21명의 젊고 건강한 성인 남자 (평균연령±SD=25±2.3)를 대상으로 Polar??F i t n e s T e s t를 일정한 간격으로 2회 반복 시행하여 추정된 최대 산소섭취량을 구하였고 동일한 대상에게 트레드밀 검사를 시행하여 최대 산소섭취량을 실측하였다 . 반복 시행한 Polar??Fitnes Test의 결과로 재검사 신뢰도를 평가하였고 Polar??Fitness Test와 트레드밀 검사 결과의 상관계수로 타당도를 평가하였다. 그리고 최대하 운동부하 검사인 전자식 에르고미터 검사를 동일한 대상에게 시행하여 추정된 최대 산소섭취량을 구하였고 실측된 최대 산소섭취량과의 상관계수로 타당도를 평가하였다 .결 과 실측한 최대 산소섭취량 (49.9±5.1ml/kg/min)과 비교하여 Polar??F i t n e s T e s t ( 4 2 . 4±2.0ml/kg/min)와 전자식 에르고미터 검사(38.5±7.2ml/kg/min)는 모두 최대 산소섭취량을 낮게 추정하였다 . 실측한 최대 산소섭취량과의 스피어만 상관계수는 Polar??Fitness Test의 경우 0.03(P=0.91), 전자식 에르고미터 검사의 경우 0.33(P=0.14) 이었으며 반복 시행한 Polar??F i t n e s T e s t의 피어슨 상관계수는 0.99(P<0.01) 였다.

Background Exercise load tests have been used for evaluation of cardiorespiratory fitness. However, they are not applicable to everyone because of special equipments to conduct and considerable time and efforts from testees. Therefore, simpler yet accurate ways of evaluation are being badly in need and Polar Fitness Test can be one of them. In this study predicted VO2max values during resting state with the Polar Fitness Test are being compared with measured VO2max values(criterion VO2max) determined during the maximal treadmill test in order to assess the validity and the reliability of the Polar Fitness Test. In so doing, the validity of the Electronic Ergometer is assessed as well. Methods Twenty one of healthy young-aged males(M±SD=25±2.3years) were volunteered for this study. Criterion VO2max values were determined during the maximal treadmill test while predicted values were achieved twice with the Polar Fitness Test at an interval of fifteen minutes. Then the correlation coefficients were calculated with the SPSS 11.0 program whether the Polar Fitness Test is valid and reliable. Same protocol was applied for the Electronic Ergometer as well. Results All the predicted VO2max values were lower than the measured values (Treadmill test: 49.9±5.1ml/kg/min; Polar Fitness Test: 42.4±2.0ml/kg/min; Electronic Ergometer: 38.5±7.2ml/kg/min). The correlation coefficients between the measured and predicted VO2max values with the Polar Fitness Test and the Electronic Ergometer were 0.03(P=0.91) and 0.33(P=0.14) respectively. The correlation coefficient between two repeated values with the Polar Fitness Test was 0.995(P<0.01).
