Document Summary
To list different components of energy expenditure. To compare contribution of different components of energy expenditure. To define basal metabolic rate (bmr) and name associated factors. To describe how to measure bmr and basal energy expenditure (bee) To compare resting metabolic rmr and bmr. To describe thermic effect of food (tef) and compare macronutrients tef. How to measure energy expenditure in physical activity. Energy intake = energy expenditure (carbohydrate, fats, proteins, alcohol) into body out of body (basal metabolic rate, thermic effect of food, physical activity, thermic regulation) = energy to sustain basic life processes including: Synthesis of proteins and other complex molecules. Liver (27%), brain (19%), kidney (10%), heart (7%) = almost 65% of bmr. Skeletal muscle = 18% of bmr (for protein synthesis and normal cell function) Many of these factors can be attributed the amount and proportion of lean mass. In aging fat mass increases while fat free mass increases.
