Ch. 16 Plyometric Training

Question 1

stretch-shortening cycle

Answer 1

the countermovement involved in plyometric exercise

Question 2

power

Answer 2

the force-speed relationship

Question 3

series elastic component (SEC)

Answer 3

it acts as a spring and is lengthened; as it lengthens, elastic energy is stored

Question 4

potentiation

Answer 4

change in the force-velocity characteristics of the muscle’s contractile components caused by stretch

Question 5

stretch reflex

Answer 5

the body’s involuntary response to an external stimulus that streches the muscles

Question 6

Muscle spindle

Answer 6

proprioceptive organs that are sensitive to the rate and magnitude of a stretch

Question 7

eccentric phase

Answer 7

thephase in which a muscle is relaxing

Question 8

amortization phase

Answer 8

the time between the eccentric and concentric phases

Question 9

concentric phase

Answer 9

the body’s response to the eccentric and amortization phases

Question 10

complex training

Answer 10

a combination of high-intensity resistance training followed by plyometrics

Question 11

balance

Answer 11

the maintenance of a position without moving for a given period of time
