To understand muscles, you have to know about H2O, water, and oxygen and hydrogen, gases in water.
You also have to know what fats and types of sugar are for. Fats and sugar separate H2O and keep oxygen and hydrogen separated in gaseous form and when insulin is released, it could form water for the blood plasma.
With oxygen and hydrogen separated, the muscles absorb these gases in different types of cells and the force of attraction, which the hydrogen field generates with oxygen, to form H2O or water, is the force of contraction that the muscle will generate.
For example, with hydrogen-rich cells and oxygen-rich cells, the force is greater, depending on the amount of gases added together, but there are several factors.
Muscle cells contain proteins that form microscopic tendons and slide one layer over another and then contain other proteins, which empty the muscle cell of oxygen and the proteins dissolve often, emptying the cell of oxygen, many times repetitively and sending it to the blood, to then pick it up again. This effect reduces the field of attraction of H2O and the muscle relaxes, but this effect is caused by two factors, chromosomes and chemical messengers.
Proteins do this, but it is important to know that high doses of proteins can suffocate the muscle cell and reduce its performance and also to say that viral infections can cause it, such as phages
Then, there is the nervous section, where acetylcholine acts, a neurotransmitter, which the brain sends and reaches the chromosomes, through nerve channels, where it activates the genes, to absorb gases, such as oxygen. The neurotransmitter acetylcholine activates the genes of the muscle cell and it fills with oxygen and causes the field of attraction, with other hydrogen cells and when it relaxes, the muscle and the protein, empty the cell of oxygen again and so, again, for a new movement.
In these images I leave you an example of a high intensity exercise with my data.
