Fitness levels contribute to our energy expenditure and weight control. As fitness improves it is possible to do more work at the same heart rate and level of perceived exertion; you are able to burn more energy for the same perceived effort. The term metabolism means the breakdown of foods to release energy. You can metabolise fat, carbohydrate or protein to release energy.
