1

Stretch-Shortening Cycle (SSC)

The series of three phases that explains the mechanical and neurophysiological reactions to a plyometric movement. (NSCA CPT, pg. 430)

2

Series Elastic Component (SEC)

The structures that, when stretched, have the ability to store energy that may be released upon an immediate concentric muscle action. (NSCA CPT, pg. 430)

3

Stretch Reflex

The immediate contraction of a muscle caused by a rapid stretch of that muscle. (NSCA CPT, pg. 430)

4

Potentiation

The increase in activity of the agonist muscle caused by the reflexive response of the muscle spindles and the release of stored elastic energy. (NSCA CPT, pg. 431)

5

Deceleration

A decrease in velocity. (NSCA CPT, pg. 431)

6

Amortization Phase

The time between the eccentric and concentric phases. (NSCA CPT, pg. 432)

7

Eccentric Phase of the SSC

Stretch of the Agonist muscle. (NSCA CPT, pg. 432)

8

Amortization Phase of the SSC

Pause between phases I and III. (NSCA CPT, pg. 432)

9

Concentric Phase of the SSC

Shortening of Agonist muscle fibers. (NSCA CPT, pg. 432)

10

Speed-endurance

The ability to maintain running speed over an extended duration. (NSCA CPT, pg. 446)

11

Speed-strength

The application or development of maximum force at high velocities. (NSCA CPT, pg. 446)

12

Sprint-assisted Training

A method to increase stride frequency by having the client run at speeds greater than he is able to independently achieve. (NSCA CPT, pg. 448)

13

Resisted Sprinting

A method to increase stride length and speed-strength by increasing the cli- ent’s ground force production during the support phase. (NSCA CPT, pg. 449)

14

Complex Training

A combination of resistance and plyometric training. (NSCA CPT, pg. 451)

15

Sprinting Technique variables

Posture, Leg action, Arm action, Acceleration. (NSCA CPT, pg. 446)

16

Mechanical Model of Plyometric Exercise

Elastic energy is stored following a rapid stretch and then released during a sub- sequent concentric muscle action, thereby increasing the total force production. (NSCA CPT, pg. 430)

17

Neurophysiological Model of Plyometric Exercise

A change in the force–velocity characteristics of the muscle’s contractile components caused by stretch. (NSCA CPT, pg. 430)

18

Frequency

The number of plyometric training sessions per week and depends on the client’s age, ability, and goals. (NSCA CPT, pg. 442)

19

Plyometric Volume

The total work performed during a single workout session and is typically expressed as the number of repetitions and sets performed during a session. Often plyometric volume is expressed as the number of contacts, but may also be expressed as distance, as with plyometric bounding. (NSCA CPT, pg. 443)

20

Extended Duration

Typically longer than 6 seconds. (NSCA CPT, pg. 446)
