Energy systems
-
ATP-PC (alactic)
-
Muscle cell has a small amount of ATP in it that can be used immediately, there is only enough for about 3 seconds.
High intensity,low duration
-
When a high energy bond is broken, the energy it releases it transferred to ADP to resynthesise ATP
-
If exercise continuous at a high intensity these stores will only partially replenish, not enough energy available for creatine and phosphate.
-
-
Lactate system
Short-term energy systemand is used to meet energy requirements of higher internsity over alonger period
Anaerobic process that does not require oxygen and therfore is not sustainable over a long duration.
