Definitions:

Muscle Fatigue

Muscle fatigue is the decline in ability of a muscle to generate force, often experienced after prolonged activity or strain.

Motor Units

A motor unit consists of a single motor neuron and all the muscle fibers it innervates, essential for muscle contraction.

All Or None

A principle stating that a neuron either fires with a full response or does not fire at all, depending on stimulus strength.

Contraction

The process in which a muscle becomes shorter and tighter, producing movement or exerting force.
