Chapter 18 - Plyometric (Reactive) Training Concepts

Question 1

Plyometric training

Answer 1

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

Question 2

Ground reaction force

Answer 2

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

Question 3

Rate of force production

Answer 3

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

Question 4

Stretch-shortening cycle

Answer 4

loading of a muscle eccentrically to prepare it for a rapid concentric contraction

Question 5

Integrated performance paradigm

Answer 5

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

Question 6

Eccentric phase

Answer 6

Preloading/stretching of agonist muscle

Question 7

Amortization phase

Answer 7

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

Question 8

Concentric phase

Answer 8

shortening of agonist muscle

Question 9

Neuromuscular efficiency

Answer 9

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
