Abstract
The supply of ATP is critical for ongoing skeletal muscle contractile activity during exercise. The metabolic pathways in muscle that ensure continual ATP supply are PCr degradation, glycolysis, and the oxidative metabolism of CHO (muscle glycogen and blood glucose) and fat (muscle triglyceride and plasma fatty acids). The relative contributions of these metabolic pathways are primarily determined by exercise intensity and duration but also influenced by training status, preceding diet, sex, and age. Various interventions designed to enhance sporting performance target the availability and utilization of metabolic substrates. In addition, metabolic perturbations and metabolic communication during exercise play key roles in the acute and adaptive responses to exercise.
