Dear student
The neural response of the body to this charge is to recruit muscle fibres to complete the task, but muscle fibers get tired very quickly. This is due to the major source of energy for the muscle tissue, called adenosine triphosphate, or ATP. As the muscles make use of this supply of energy, they get tired and fatigue.
