NASM-CPT (7th Edition) Chapter 18

Plyometric Training

Exercises that generate quick, powerful movements involving an explosive concentric muscle contraction preceded by an eccentric muscle action.

Ground Reaction Force (GRF)

Reaction force imparted by the ground on the body when a body segment makes contact with it.

Rate Of Force Production

Ability of muscles to exert maximal force output in a minimal amount of time.

Stretch Shortening Cycle

Loading of a muscle eccentrically to prepare it for a rapid concentric contraction.

Integrated Performance Paradigm

To move with efficiency, forces must be dampened (eccentrically), stabilized (isometrically), and then accelerated (concentrically).

Amortization Phase

The transition from eccentric loading to concentric unloading during the stretch-shortening cycle.

Neuromuscular Efficiency

The ability of the nervous system to recruit the correct muscles to produce force, reduce force, and dynamically stabilize the body's structure in all three planes of motion.
