THE ROLE OF FATS AS THE MAIN SOURCE OF ENERGY IN THE PROCESS OF ADAPTATION TO AEROBIC PHYSICAL ACTIVITY

Summary. The article explores the role of fats in meeting the need for energy in the process of adaptation to the loads of aerobic exercise. Fats begin to play the role of the main source of energy, since when performing prolonged physical exertion in muscle activity, not very large reserves of carbohydrates are sharply reduced. To meet the energy needs of aerobic physical activity, the mobilization of lipid-derived metabolites accumulated in fat depots and inside skeletal muscle cells is important. Mobilization of lipolysis products (mainly triglycerides) from adipose tissue and skeletal muscles, the interdependence between them allows you to regulate fat metabolism. When exposed to single and systematic physical activity, it was also known that the formation and consumption of triglycerides as an energy substrate can be regulated with the help of activators taken with food. Since an increase in the intensity of aerobic exercise also accelerates the mobilization, transport and use of intracellular triglycerides, adaptive changes in energy capacity occur, resulting in increased activity of the lipase enzyme in both adipose tissue and skeletal muscle.
