Abstract

The purpose of this study was to develop the mathematic algorithm for energy expenditure calculation during cycling as a part of the development of a higher value-added cycle. Participants were 60 university students (male 30, female 30). Energy expenditure was measured with breathing gas at 10 sec intervals by gas analyzer connected with stationary cycle ergometer. Values presented by commercial speedometer and preceding researches were used for verification of actual measurement values in this study. In conclusion, the mathematic algorithms for energy expenditure calculation during cycling were as follows. For male, energy expenditure(Kcal)=5.048×cycling time(min)-2.258, energy expenditure(Kcal)=(0.05×cycling velocity(kph))×(4.750×cycling time(min)+0.091). For female, energy expenditure(Kcal)=4.466×cycling time(min)-1.605, energy expenditure(Kcal)(cycling velocity≤20kph)=(0.05×cycling velocity(kph))×(4.151× cycling time(min)-0.736), energy expenditure(Kcal)(cycling velocity>20kph)=(0.04×cycling velocity(kph)) ×(4.151×cycling time(min) -0.736). And it is suggested that the developed algorithm with cycling time and velocity should be applied for the development of a higher value-added cycle.

본 연구는 자전거 운동 시 소비되는 에너지량 계산을 위한 알고리즘을 개발하고자 하는 목적으로 수행되었다. 대학에 재학 중인 60명(남자 30명, 여자 30명)을 대상으로 자전거 운동 시 10초 간격으로 배출하는 호흡가스를 분석하고 에너지소비량을 측정하였으며, 시판 유선속도계로 측정된 결과 및 선행연구에서의 추론식과 비교 검증하였다. 남자의 자전거운동 시 시간에 따른 소비되는 에너지량을 추정하는 알고리즘은 '에너지소비량(Kcal)=5.048×(시간(분))-2.258(r2=0.998)'로 계산되었다. 여자의 자전거 운동 중 시간에 따른 에너지소비량 추정 회귀식은 '에너지소비량(Kcal)=4.466×(시간(분))-1.605(r2=.999)'로 계산되었다. 남자의 자전거운동 시 시간과 속도에 따른 에너지소비량 추정 회귀식은 '에너지소비량(Kcal)=(0.05×속도(kph))×(4.750×시간(분)+0.091)'로 계산되었다. 여자의 자전거 운동 시 시간과 속도에 따른 소비되는 에너지량 추정 회귀식은 속도 20kph 이하 조건에서는 '에너지소비량(Kcal)=(0.05×속도(kph))×(4.151×시간(분)-0.736)'으로 계산되었고, 속도 20kph 초과 조건에서는 '에너지소비량(Kcal)=(0.04×속도(kph))×(4.151×시간(분)-0.736)'으로 계산되었다. 결론적으로 자전거 운동 시 소비되는 에너지량을 계산하기 위한 알고리즘개발에는 시간 및 속도에 따른 에너지소비량 추론식 적용이 적절한 것으로 제언된다.
