Regular aerobic training increases the size and number of mitochondria making the body more efficient at burning fat.

By improving the utilisation of fatty acids, the body is able to use less glycogen which is in much shorter supply.

These are held together by high energy bonds, which when broken, produce energy.

During exercise, energy is needed at a faster pace – muscles contract more frequently, the heart beats faster, etc. ATP is made up of one molecule of adenosine and three phosphates.

ATP is stored in small amounts in the muscle fibres and when one of its phosphate bonds is broken, , is formed together with energy and heat production (this is why people get hot when exercising).

ATP → ADP energy for contraction Muscle stores of ATP are limited.

There are 2 anaerobic systems: (also called the creatine phosphate or PC or phosphocreatine system) Muscular contractions need ATP (stored in muscles).

Energy is immediately available but stores are very small and will only give enough energy for a few seconds.

This extra oxygen is known as the oxygen debt, and it helps to remove the build-up of lactic acid, replenish the stores of oxygen in the body, and build up the ATP and creatine phosphate stores in the muscles.

Bioenergetic Systems and Training As athletes, we know that our bodies need energy to function.
