The nervous system can make very quick changes in a fraction of a second by sending electrical impulses through the spinal cord to the muscles, or it can make slow changes by sending chemical messengers, called hormones, into the blood to reach the tissues and the organs.

Traditionally, it was thought that the there were three main factors that derived from CNS activity that subsequently affected EMG amplitude: the motor unit recruitment extent, the motor unit firing frequency, and the synchronisation of these electrical impulses (with greater synchronisation perhaps implying greater neural drive from the CNS)(see review by Behm, 1995).
