Abstract

The purpose of this study was to examine the effect of exercise and diet control program on nitrogen balance in obese children. The subjects of this study were five obese boys aged from 8 to 12 participating in the control period(C) for 3 days, exercise without energy deficit period(EEN) for one week, and exercise with energy deficit period(EED) far another one week, consecutively. The intensity of the exercise was 60-70% of HRmax and the energy was restricted at 493 kcal/day. Daily mean total energy intake was 2,152 $\pm$ 138kca1, 1,861 $\pm$ 138kca1, and 1,368 $\pm$ 87kca1 for the period C, EEN and EED, respectively. The body weight for EEN and EED decreased compared with the period C by average 1.2 $\pm$ 0.2kg and 1.8 $\pm$ 0.3kg, respectively. Of the body weight loss, the fat mass decreased bur 1.0 $\pm$ 0.3kg and 1.5 $\pm$ 0.5kg and the lean body mass by 0.2 $\pm$ 0.4kg and 0.3 $\pm$ 0.4kg, respectively. Of the daily mean nitrogen consumption was 9.1 $\pm$ 0.7g, 9.1 $\pm$ 0.8g and 7.1 $\pm$ 0.5g, the daily mean nitrogen excretion from feces was 1.3 $\pm$ 0.2g, 0.9 $\pm$ 0.1g and 0.7 $\pm$ 0.1g, and from urine was 6.7 $\pm$ 0.6g, 6.6 $\pm$ 0.5g and 6.7 $\pm$ 0.6g, for the period C, EEN and EED, respectively. Daily mean nitrogen balance excluding nitrogen excretion firm feces and urine indicated + 1.1 $\pm$ 1.0, +1.6 $\pm$ 0.6 and - 0.3 $\pm$ 0.9 for the period C, EEN and EED, respectively. Despite the negative indication during EED, there was no statistical signifiranre. The daily mean creatinine excretion was 0.5 $\pm$ 0.0g, 0.7 $\pm$ 0.1g and 0.6 $\pm$ 0.0g and the creatinine-height index(CHl) was 85.1 $\pm$ 6.7%, 83.8 $\pm$ 6.6% and 81.0 $\pm$ 6.5%, for the period C, EEN and EED, respectively, indicating little significant difference among the periods. Taking above results into consideration, it seems the exercise program conducted for this study did not substantially affect the nitrogen balance of the obese children, and may be used far the body weight control. Howeever, the adequacy of the energy restriction and amount of exercise applied to this study need to be further investigated as the nitrogen balance indicated negative and increasing tendency of the creatinine excretion showed during the EED compared with period C, despite the statistical insignificance.

본 연구는 운동 및 식이 조절이 비만 아동의 질소 평형에 미치는 영향을 조사하기 위하여 8~12세의 비만한 초등학교 남자 아동을 대상으로 3일간은 대조기간 1주일간은 운동을 부하하되 에너지는 제한하지 않는 운동기간 및 그 후 1주일간은 운동부하와 동시에 에너지를 제한하는 에너지 제한 운동기간으로 나누어 대상자의 체중 및 체성분을 측정하고, 또한 에너지 섭취량, 질소 평형 및 CHI를 측정하여 상호 비교하였다. 1일 평균 총 에너지 섭취량은 대조기간, 운동기간 및 에너지 제한 운동기간별로 각각 평균 2,152 $\pm$ 138kca1, 1,861 $\pm$ 138kca1 및 1,368 $\pm$ 87kca1이었다. 체중은 대조기간에 비하여 운동기간 및 에너지 제한 운동기간 별로 각각 평균 1.2 $\pm$ 0.2kg 및 1.8 $\pm$ 0.3 kg 감소되었데, 이 중 지방 조직은 각각 평균 1.0 : 0.3kg 및 1.5 $\pm$ 0.5kg 감소되었고 무지방 조직은 각각 평균 0.2 $\pm$ 0.4kg 및 0.3 $\pm$ 0.4kg 감소되었다. 1일 질소 섭취량은 대조기간, 운동기간 및 에너지 제한 운동기간별로 각각 평균 9.1 $\pm$ 0.7g, 9.1 $\pm$ 0.8g 및 7.1 $\pm$ 0.5g 이었는데 대변으로의 질소 배설량은 기간별로 각각 평균 1.3 $\pm$ 0.2g, 0.9 $\pm$ 0.1g 0.7 $\pm$ 0.1 이었으며 소변으로의 질소 배설량은 기간별로 각각 평균 6.7 $\pm$ 0.6g, 6.6 $\pm$ 0.5g 및 6.7 $\pm$ 0.6g 이었다.
