Phospcreatine
Every time this reaction series is complete one atp is created, however the recovery period can take any where between 30secs and 5 mins this depends on the altheas, this can be trained to recover quicker.
Lactic acid system
The recovery period for the lactic acid system time also depends on the athlete and how much they have trained as it can vary from in between 20-120mins.
Aerobic energy
Electron transports system-oxgyen combines with the hydrogen this creates water, the water has to leave the body it doe this throught sweat and other methods.
Depending on the rescores is how much energy is created, with fatty acids it can be 129atp and with glucose it is 38atp. The recovery period depends on how you keep your body rest is needed so the fibres in the muscles can repair, the replenishment of fluids and food.
This energy system is a quick sudden burst and provides immediate energy If this energy system is full it will provide energy for maximal intensity, and a very short duration only last around 10-15s, this cant only be trained a bit and will not have much effect.
Initially ATP stored in the body is broken down to release energy for movment. This leaves the secondly products of ATP breakdown: adenosine diphosphate (ADP) and one single phosphate (Pi) all on its own.
Phosphocreatine (PC) is then broken up into Creatine and Pi this is done by creatine kinase.
Energy is then released in the breakdown this allows ADP and Pi to rejoin forming more ATP.
