What is ATP energy?
The only form of energy your body can use is in the form of a molecule called ATP, which stands for Adenosine-Tri-Phosphate.
Imagine your body is a car. ATP would be the gasoline that you constantly need to keep it running. That is unless you are driving an electric car...
What is ATP used for?
So, whether you are walking up the stairs, going for a jog or pumping some iron, your body will need ATP to fuel your activity.
ATP is a big and heavy molecule so we cannot carry a huge amount of it around. As a result, it has to be synthesized when we need it. Meaning our body has to create it through the combination of different elements.
How does ATP work during exercise?
The ATP synthesis can come from either, your body "burning" nutrients when there is oxygen present (aerobic) or from chemical reactions when no oxygen (anaerobic) is present.
The most ATP can be made from fat metabolism, but this process is very slow and therefore not ideal when working at moderate to higher intensities.
To give you an idea, the same amount of glucose/glycogen, which comes from carbohydrates, only provides about a quarter of the ATP compared to the ATP synthesis from fat.
While fat is more efficient at creating ATP, burning glucose/glycogen is roughly twice as fast.
This is where the "fat burning zone" idea comes from. At lower intensities, the muscle can re-synthesize enough ATP by primarily using fat, but as intensity increases, the rate at which ATP is used also increases. To keep working at the higher intensity, the rate of ATP re-synthesis has to match it.
This higher intensity will switch the energy turnover from fat towards the use of glucose/glycogen (carbohydrates), which again, re-synthesizes ATP faster than burning fat, but is not as "efficient".
Similair to a hybrid car. When needing to be more efficient, it will run off electricity, but when you slam on the peddle, it will use gas to get it moving faster. In this case, fat is the electricity, while glucose/glycogen is the gasoline.
However, it is well documented and known that the key factor when looking to burn or lose fat is the amount of work done (total amount of calories used) and not really where the energy is coming from. This is partially why there has been a shift from long, low-intensity exercise to shorter, moderate to higher intensity exercise.
The anaerobic (without oxygen) pathways are capable of regenerating ATP at high rates, yet are limited by the amount of energy that can be released in a single bout of intense exercise. In contrast, the aerobic (with oxygen) system has an enormous capacity but is somewhat hampered in its ability to deliver energy quickly.
