Chapter 18: Lesson 1

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

Amortization phase

Answer 6

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

Question 7

Neuromuscular efficiency

Answer 7

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.
