Intra-individual variations in resting metabolic rates of human subjects.

The resting metabolic rates (RMRs) of 5 male subjects of body mass index around 20 were estimated for 6 consecutive weeks on a 5 X 5 randomized Latin Square design. Analysis of variance (ANOVA) showed a distinct training effect with an exponential decline in RMR of all the subjects, while the mean of the coefficient of variation of intra-individual and inter-individual differences were of the order of 3.1 and 5.8 per cent respectively. The coefficient of variation of the measurement error was 2.93 per cent.
