On the other side, charged particles, or ions, line the muscle cell’s membrane: potassium on the inside, and sodium on the outside.
In response to a signal from the brain, the motor neuron releases acetylcholine, which triggers pores on the muscle cell membrane to open.
The flux of these charged particles is a crucial step for muscle contraction: the change in charge creates an electrical signal called an action potential that spreads through the muscle cell, stimulating the release of calcium that’s stored inside it.
This flood of calcium causes the muscle to contract by enabling proteins buried in the muscle fibers to lock together and ratchet towards each other, pulling the muscle tight.
This whole process repeats every time a muscle contracts.
Though muscle cells use up ATP as they contract repeatedly, they are always making more, so most of the time even heavily fatigued muscles still have not depleted this energy source.
But eventually, over the course of repeated contractions there may not be sufficient concentrations of potassium, sodium or calcium ions immediately available near the muscle cell membrane to reset the system properly.
So even if the brain sends a signal, the muscle cell can’t generate the action potential necessary to contract.
Even when ions like sodium, potassium or calcium are depleted in or around the muscle cell, these ions are plentiful elsewhere in the body.
So if you pause and rest, muscle fatigue will subside as these ions replenish throughout the muscle.
The more regularly you exercise, the longer it takes for muscle fatigue to set in each time.
