초록/요약
The necessity of a 12-h fast before resting metabolic rate (RMR) is measured is often a barrier to measuring RMR. To investigate the relationship between resting metabolic rate (RMR) and thermic effect of food (TEF; 4 hour after a 316.6kcal meal) were measured by indirect calorimetry (TrueOne2400, USA) in 32 young subjects. In addition, the influence of body composition on this relationship was studied. RMR measurements were made in the morning (after a 12-h fast and 12 h postexercise) and in the afternoon (after a 4-h fast and 12 h postexercise). Body composition was assessed by Inbody720. The average age of the subjects was 4.5 ± 0.8 years. Average height, weight, body fat(kg), body fat(%), fat free mass, Rohrer index, Kaup index and Obesity index of subjects were 107.8 ± 6.8 cm, 19.1 ± 4.1 kg, 3.9 ± 2.4 kg, 19.7 ± 7.8%, 15.2 ± 2.4 kg, 151.1 ± 15.4, 16.3 ± 1.9 and 104.9 ± 12.0%, respectively. Mean afternoon RMR (743.2 ± 147.1 kcal/day) was significantly higher than morning RMR(893.0 ± 181.1 kcal/day). The mean difference between the morning and afternoon measurements was 150 kcal/day. RMR correlated best with fat free mass (r= 0.390, r= 0.400), muscle mass (r= 0.381, r= 0.396), height (r= 0.362), body surface area (r= 0.360, r = 0.398), weight (r= 0.396). RMR measured in the afternoon after a 4-h fast and exercise was 150 kcal/day higher than RMR measured in the morning. As a result of this research it could be conclude that the accuracy of a measurement of RMR 4 h later.
