What Is The Best Source Of Energy During Exercise

What summarizes the relationship best is moderate exercise like a 10 or 15 minute walk has the primary effect of increased energy while very intense exercise like working out at the.

What is the best source of energy during exercise.

The process by which fatty acids and other sources are converted to energy during low intensity exercise. And anaerobic glycolysis the breakdown of glucose which is the primary energy source for high intensity exercise of one to three minutes say an 800 meter race. As exercise intensity increases the number of calories burned also increases. During exercise there are four major endogenous sources of energy.

Nutrients provide the energy sources for all forms of exercise. During physical exercise stored carbohydrate or glycogen is converted into energy to fuel the muscles but this supply is not endless. Phosphocreatine as with all out 100 meter sprints exercise under 30 seconds. Muscle carbohydrate stores glycogen blood sugar blood fatty acids and intramuscular triacylglycerols.

High intensity exercise of a short duration requires anaerobic sources of atp. While at rest and during low intensity exercise free fatty acids are the predominant energy sources. The extent to which these substrates contribute energy for exercise depends on the intensity and duration of exercise the level of exercise training the initial muscle. Fat is your body s preferred source of energy for low intensity exercise.

The amount of carbohydrate that can be stored in the body as glycogen depends on diet and the athlete s conditioning level. An alternative energy source to protein being used for energy.
