The three energy systems fall into 2 groups: anaerobic and aerobic. There is 1 aerobic energy system, but 2 anaerobic systems, which are: the alactacid or ATP/PC system and the lactic acid system. It is vital in understanding these systems, that their interrelation is understood. Each energy system produces ATP used to create movement and [...]
The aerobic energy system is your diesel-powered semi-trailer. It takes a while to warm up, but once it is going, it goes the distance producing plenty of ATP with great efficiency. This energy system uses fats, carbs, and protein to produce plenty of ATP, but produces them at a slower rate compared to the two [...]
The lactic acid energy system can be likened to a powerful SUV that emits plenty of smog. This energy system is fast and maintains good power, with limited endurance and a whole lot of waste product that hurts. This system last 1-3min and produces ATP quickly, but uses a lot of carbohydrate (its fuel source) to [...]
The alactacid energy system also known as the ATP/PC system is the Ferrari of the energy systems. It has all the glamour of the 100m sprint and provides the energy used for power and strength. This system has lots of power, but uses its fuel without care. When used flat out it lasts no more than [...]
