Chapter 8: Plyometric Training Concepts

Question 1

Stretch-shortening

cycle

Answer 1

An active stretch (eccentric contraction) of a muscle followed by an immediate shortening (concentric contraction) of that same muscle.

Question 2

Plyometric training

Answer 2

Exercises that utilize quick, powerful movements involving an eccentric contraction immediately followed by an explosive concentric contraction.

Question 3

Eccentric phase

Answer 3

This phase increases muscle spindle activity by pre-stretching the muscle prior to activation.

Question 4

Amortization

phase

Answer 4

The electromechanical delay a muscle experiences in the transition from eccentric (reducing force and storing energy) to concentric (producing force) muscle action.

Question 5

Concentric

contraction

Answer 5

Occurs immediately after the amortization phase and involves a concentric contraction.

Question 6

Plyometric-stabilization training

Answer 6

Plyometric exercises designed to establish optimum landing mechanics, postural alignment, and reactive neuromuscular efficiency.

Question 7

Plyometric strength training

Answer 7

Designed to improve dynamic joint stabilization,

eccentric strength, rate of force production, and neuromuscular efficiency.

Question 8

Plyometric-power

training

Answer 8

Plyometric exercises are performed as fast and as explosively as possible.

Question 9

PEC

Answer 9

Parallel elastic component

Question 10

SEC

Answer 10

Series elastic component

Question 11

CC

Answer 11

Contractile component
