What is the Origin of Neurological Potentiation?

The term combines 'neurological,' relating to the nervous system, with 'potentiation,' derived from the Latin potentia meaning 'power' or 'ability to do something.' This concept originated from neurophysiological studies demonstrating that a brief, intense stimulus can temporarily enhance a reflex or response. In exercise science, it is applied to the temporary performance boost after a heavy lift.

What is the Mechanism of Neurological Potentiation?

The primary mechanism involves the phosphorylation of myosin regulatory light chains within the muscle, which increases the muscle's sensitivity to calcium, thereby improving the efficiency of the excitation-contraction coupling. Additionally, a preceding maximal effort stimulus can enhance the efferent neural drive to the motor neuron pool, resulting in greater recruitment and a higher firing frequency in the subsequent effort. This enhanced neural readiness translates directly into a higher peak force output.

Neurological Potentiation

Meaning

Neurological Potentiation is a transient or sustained increase in the excitability of the central and peripheral nervous system, leading to a temporary enhancement of force production capability. This acute phenomenon, often referred to as Post-Activation Potentiation (PAP), can be harnessed clinically to improve subsequent high-intensity performance. It represents a temporary optimization of the neuromuscular system’s readiness to generate maximal efferent neural output. This state allows for a momentary expression of supra-maximal strength.
