Question
The following rates of energy expenditure (in kcal/day) obtained using 1) indirect calorimetry (resting energy expenditure), 2) the Harris Benedict equation (basal metabolic rate) 3) daily energy need based on the Harris Benedict equation and the subject's activity 1. How did the measured resting energy expenditure compare to the estimation of Basal Metabolic Rate fronm the Harris Benedict method? Would you expect BMR to be greater or smaller than RMR? Why? 2. What factors influence basal metabolic rate in individuals? Which factor is the most important? What factors can affect the accuracy of your resting metabolic rate measurement (i.e. things that might introduce error)? Give at least 3 factors (i.e. environmental, physiological and psychological)Explanation / Answer
Resting energy expenditure-Whole body metabolism of any living being under strict resting conditions determined by biological equilibrium.
Basal metabolic rate- The body metabolism of living being under normal physiological state.
Eventhough both RMR and BMR represent the same metabolic rate the BMR is very accurate and slightly greater when compared to RMR.
The RMR is influenced by Biological factors like age, sex, and the BMR is influenced by both biological, physiological and psychological factors like age, sex, environment, activity, rest, behaviour, stress, fear, etc.
