식이제한과 운동 트레이닝이 흰쥐의 에너지 대사와 체성분에 미치는 영향

다국어 초록 (Multilingual Abstract)

This study investigated the effect of food restriction combine with endurance exercise training on lipogenic enzymes activities and resting energy expenditure in female rats. Fourty Sprague-Dawley female rats 10 wk of age were grouped as CN-SED, CN-EX, FR-SED, and FR-EX in the present study. The CN continued to receive the average amount of meal and water ad libitum. FR was restricted 70% of CN intake. Exercise training was gradually increased as 8% incline, 28 m/min, 30 min/d, and 5d/wk for 9 wks. Resting energy expenditure (REE), serum glucose, free fatty acid (FFA), insulin and lipogenic enzymes, malic enzyme (ME), glucose-6- phosphate dehydrogenase (G6PD) and lipoprotein lipase (LPL) activities, were analyzed. Body fat accumulation in abdomen was significantly lower in FR than CN (p<.05). Carcass fat showed lower accumulation in FR than CN (p<.05). REE during 6 h of pre and postprandial was shown in Fig. 3. FR-SED was significantly lower energy expenditure 2-4 h after the meal (p<.05). CN-EX was significantly higher 1 h after the meal than FR-SED (P<.05). FR and/or exercise training affected preprandial REE. Lipogenic enzymes, G6PD, ME, were significantly higher in FR-EX than the other groups (p<.05). This result suggesting that FR and/or exercise training increased lipogenic enzyme activity, especially with exercise training, even though body fat was reduced.
