adenosine triphosphate or ATP, a molecule found in all living things and is the main energy source used by cells to carry out their activities. This molecule is used by the muscles when they need to perform a contraction that is the source movement. The energy required is produced or released from the rupture of the links on this molecule.
The muscle cell contains a very small amount of ATP action at the contraction - relaxation can not be sustained beyond 7 seconds. In order to continue with this activity you should get a constant regeneration of ATP.
How can we get this feedback? Simple, through the foods that are metabolized into new molecules of ATP through what are called pathways energy.
ATP is a metabolic intermediate in the energy flow between the substrates of energy and energy processes at the cellular level. The muscle cell has the ability to adapt the production of ATP to the energy needs of each moment, so that it can increase several times the energy requirements in a short time depending on the type of physical activity.
The ATP concentration or cell reserve is low and does not change with training, so that in the human muscular agility for energy as needed, lies the success or failure of the activity matter physics. It is important to note that if the ATP needs are greater than their availability, one must resort to other metabolic pathways such as carbohydrates, fats and proteins, both to replenish ATP to create it.
