The best sources of energy during exercise are carbohydrates and fats. Carbohydrates provide quick energy for high-intensity activities, while fats are used for longer, lower-intensity exercises. It's important to have a balanced diet to fuel your body effectively during physical activity.
After 3 hours of exercise, the main sources of energy utilized by the body are carbohydrates stored in muscles and liver, as well as fats stored in adipose tissue. These energy sources are broken down to provide fuel for the muscles to continue working during prolonged physical activity.
During exercise, the best forms of carbohydrates to consume are easily digestible sources such as sports drinks, energy gels, or bananas. These provide quick energy to fuel your workout without causing digestive issues.
During rest and low-intensity exercise, muscles rely on stored glycogen as a source of energy. Glycogen is broken down into glucose, which is used for fuel by the muscles. If glycogen stores are depleted, the body may turn to other sources of energy, such as fat.

During high intensity exercise, muscles primarily get their energy from stored glycogen in the muscles and glucose in the bloodstream.

Besides the obvious increased caloric expenditure during aerobic exercise, long-term aerobic exercise appears to change what sources of energy we use during such activity. Studies examining trained and untrained people exercising have found that trained participants will rely more on stored fat during exercise than untrained ones. Additionally, you will continue to burn an increased number of calories for about an hour or so after stopping exercise (as your body uses energy to help recover).
The utilization of glycogen in exercise is important for providing energy to muscles. When glycogen stores are depleted, performance and endurance can decrease as the body relies on other energy sources. Proper glycogen management through nutrition and training can help improve overall performance and endurance during exercise.
No. You get energy and nutrients by eating food. During exercise the energy is spent
During exercise, cellular respiration is the process by which cells break down glucose to produce energy in the form of ATP. This energy is used by muscles to contract and perform physical activities. The increased demand for energy during exercise leads to an increase in cellular respiration to meet the body's energy needs.
