Energy Intake, Expenditure and balance 0.0 / 5 ? Physical EducationExercise physiologyA2/A-levelAQA Created by: Grace Bowman WHSCreated on: 02-07-19 17:00 Energy intake, expenditure and balance Exercise Physiology 1 of 7 What is energy expenditure? The sum of basal metabolic rate, the thermic effect of food and the energy expended through physical activity. 2 of 7 What is the basal metabolic rate? The minimum amount of energy required to sustain essential physiological function at rest (75% of total energy expenditure) 3 of 7 What is the thermic effect of food? The energy required to eat, diges, absorb and use food taken in, which accounts for a very small percentage of the total energy expenditure. 4 of 7 What is the physical activity energy expenditure? The total number of calories required to perform daily tasks, which can be estimated using MET values (30% of total energy expenditure). 5 of 7 What is the metabolic equilvalent (MET) value? The ratio of a performer's working metabolic rate to their resting metabolic rate. 6 of 7 What is MET value 1? The amount of energy expended in one hour at rest. Calculated by dividing BMR by 24. 7 of 7
