Energy Balance 3.0 / 5 based on 1 rating ? AllUniversityNone Created by: RuthCreated on: 08-05-13 10:42 What is BMR? Basal metabolic rate, energy expenditure in post absorptive state measured under standardised conditios of thermal neutrality awake but at rest. 1 of 9 What is RMR? Resting metabolic rate is the energy expenditure at rest nots under strict conditions. 2 of 9 What is PAR? Physical activity ratio is the cost of physical activity as a ratio of BMR 3 of 9 What is PAL? Physical activity level is the sum of PAR*time, expressed as a ratio of BMR. Desirable is 1.7 however average is 1.4 4 of 9 What is DIT? Diet induced thermogenesis is the increased energy expenditure after a meal which may be 10-15% energy yield of teh meal. 5 of 9 What is TEE? Total energy expenditure= (PAL*BMR)+DIT 6 of 9 What is direct calorimetry? Measurement of heat output. 7 of 9 What is indirect calorimetry? Measurement of oxygen consumption using dual isotonically labeled water. 8 of 9 What values does BMR vary between? 5.07MJday-1 to 8.67MJday-1 9 of 9
