In order to produce mechanical energy through muscular activity, the body must oxidize chemical energy, carbohydrate, fat, or protein through metabolic processes, which then results in the production of ATP as mechanical energy through exercise. Total body metabolism, specifically skeletal muscle depends on factors such as the intensity and duration of exercise, substrate availability, and Training status. During exercise at low intensities (25% of VO2 max) fat is the primary macronutrient that is oxidized for energy. As the exercise intensity progresses, (65% of VO2 max) there is an alteration in skeletal muscle utilization, which results in mainly the use of ...
