AEROBIC VS ANAEROBIC

When we use our body for practising exercise or even for making the things that we do everyday, we need and energy to be able to have the capacity of actually doing it. For that, our body uses two types of different metabolism to provide the fuel needed to our muscles: AEROBIC and ANAEROBIC. There's some differences between them that we must understand if we want to know how our body works.
 
ANAEROBIC METABOLISM: 

- Is the one we use when a lot of effort is necesary but not for a very long time (short burst of energy); for example, when we go for an sprint.
- What occurs is that our lungs cannot put the amount of oxigen needed into the bloodstream to our body to keep working properly, so our body creates energy through the combustion of carbohydrates in the absence of oxygen.

AEROBIC METABOLISM:

- Other way, anaerobic metabolism is the one we use when we do a longer exercise, which also needs a big amount of enery, but that will be provided little by little during a longer time; for example, when we go running, cycling or walking.
- In this case, our body creates the energy we need by burning carbohydrates, amino acids and fats in the presence of oxygen.



When we practise a sport or we make excercise activities, our body changes from one metabolim to another depending on what it needs in that moment.
Anaerobic metabolism is not as efficent as aerobis metabolism is; but, on other way, the anaerobic one can only use glucose and glycogen, while aerobic can also use fats and protein.

But, after all, our body is able to choose between them and use the one that adapts better to what it needs at that moment, which is completly amazing! This is definitely a very extense and interesting topic with a lot of parts to know about, and in the end, knowing about this also means that we know about our own body.

Reading Vocabulary
