Performance Test Evaluation of the Short-Term Energy System "Sleeping" is one of these, but values of basal widely. For most types of activity, from rest up to mechanical efficiency is kept relatively constant. At age 55, it averages about 27% below values for 20-year-olds, Based on linear relationships between HR and VO2 during increasing exercise intensities Carbohydrates require 5% to 10%, and fat takes 0% to 3% at most.

The most accurate way of measuring either rate is by using a process called calorimetry. The total amount of calories an individual burns in a given day is known as total daily energy expenditure (TDEE) and it comes from several sources including RMR, the thermogenic effect of food (TEF), non-exercise activity thermogenesis (NEAT), excess post-exercise oxygen consumption (EPOC) and, of course, exercise (Ex).
