Question

What effect does fatigue have on the electrical activity of a muscle and what is the reason for this response?

Answer 1

Unless you heavily damaged your nerves or repeatedly over fired them, fatigue generally has nothing to do with the input nervous signal.

Fatigue is just a way of the nerves telling you that the muscle is over worked (due to either a lactic acid build up, stemming from too little oxygen to maintain it's function), but electrical signals don't directly stop as a result of that.
