The Energy Expenditure of Female Farmers in Kyungki Area

경기일부지역 농촌주부의 농작업에너지 대사

This study was carried out on 10 persons of female farmers to determine the energy expenditure of agricultural work. Their mean age was 44 year-old, mean daily urinary nitrogen excretion was 11.3g, and creatinine excretion was 0.183g. The energy metabolism was determined by indirect calorimetry using Douglas bag and Scholander's gas analyzer. The measured basal metabolism was 1,273 kcal per day and rest metabolism was 1,614 kcal per day. To remove seedling from the seedplot, they spent 2.479kcal per minute, to weed 2.805kcal/min, and to reap with sickle 4.58kcal/min. Energy expenditure of the same work, only sitting on the stool, was significantly reduced. Prolonged work did not change energy expenditure per minute significantly.

농업에 종사하는 여자농민 10명을 선택하여 기초대사량, 안정대사량 및 농작업대사량을 측정하였다. 평균연령은 44세로서 중년기였으며 신장 152.5cm, 체중 53kg, 하루중 뇨의 질소배설량은 11.39 및 creatinine 배설량은 0.783g이었다. 기초대사 측정시 Energy소비량은 0.884kcal/min이며 이를 하루로 환산하면 1,273kcal였다. 안정대사는 1.21Kcal/min를 쓰며 하루는 1,614Kcal를 나타냈다. 농작업에 따른 Energy 소비량은 모찌기 2.479Kca1/min 김매기 2.805Kcal/min 및 벼베기 4.582Kcal/mul 등이며 보조기구인 깔개를 사용할 때는 모찌기 2.099Kcal/min 폿트작업 1.646Kcal/min 및 마늘종자심기 2.242Kcal/min으로서 깔개를 사용치 않을 때보다 유의적으로 낮아졌다. 작업시간이 길어진다고 하여도 분당 Energy 소비량은 유의적인 변화가 없었다.
