ENERGY SYSTEMS

There is only a limited store of ATP - PC in each person. ATP - PC breaks down into smaller things and there is a chemical reaction. ATP - PC can only work for activities that last 10 seconds or less so for example 100 metre sprinters would rely on this energy source and so would long jumpers. In ATP - PC the C is creatine, creatine can be found in foods and when we eat foods its like a charger. We did a activity in the gym where we did the leg press weights, where

we had to try and lift the heaviest weight that we could, we also had to do press ups and pull ups. the reason why we did these exercises was because they are activities where we use short and quick bursts of energy.

 

 

Glucose is sugar and it could be in are muscles, the chemical reaction is called Glycolysis. The glucose is broken dwon and frees up the molecules - PC. This allows the ATP system and PC system to take place again. The bad thing is the latic acid, the glycolysis takes up to 40 - 60 seconds for it to take place.

The latic acid can cause it to hurt the muscles and can also cause people to fatigue, this sort of energy system would most likely be used in the 400 metres and 200 metres swimming.
