3. Points of Caloric Expenditure Calorie: A unit of measure for energy. The body’s energy needs depend on factors such as body size, body composition, age, and type and amount of exercise. The heart rate during exercise is a direct reflection of the intensity of the activity and the increased energy expenditure over that expended during rest. An increase in heart rate is an increase in caloric output. The energy released during muscle contraction is known as the energy expenditure.

4. Points of Caloric Expenditure The more time you spend at an activity the more energy you use. Higher intensity activities require more energy than lower intensity activities. Larger people tend to require more energy for the same task than smaller people do. Activities involving a large amount of muscle mass burn more calories than those involving limited muscle mass.
