Chapter 16: Plyometric Training
Questions Correct Answers
New Update
plyometric exercise - answer -those activities that enable
a muscle to reach maximal force in the shortest time
possible
-a quick, powerful movement using a prestretch or
countermovement that involves the Stretch Shortening
Cycle
-purpose to increase power of subsequent movement by
using the natural elastic components of muscle, tendon,
and the stretch reflex
Mechanical Model of Plyometric Exercise - answer -Elastic
energy in the musculotendinous components is increased
with a rapid stretch and then stored
-If a concentric muscle action follows immediately, the
stored energy is released, increasing the total force
production
-uses the Series Elastic Component (SEC)
series elastic component (SEC) - answer -when stretched,
stores elastic energy that increases the force produced if
rapidly used or dissipates as heat
-workhorse of the plyometric exercise, particularly the
mechanical model
-tendons constitute majority of increased forced
production
, neurophysiological model - answer -involves potentiation
of the concentric muscle action by use of the stretch reflex
-rapid stretch activates the muscle spindles resulting in
increased forced production
potentiation - answer -part of neurophysiological model
of plyometrics
-change in the force-velocity characteristics of the
muscle's contractile components caused by stretch
stretch reflex - answer -part of neurophysiological model
of plyometrics
-the body's involuntary response to an external stimulus
that stretches the muscles
stretch-shortening cycle (SSC) - answer -employs both the
energy storage of the SEC and stimulation of the stretch
reflex to facilitate maximal increase in muscle recruitment
over a minimal amount of time
-broken into 3 phases: eccentric, amortization, and
concentric phases
eccentric phase - answer -first phase of SSC
-first stage of plyometric movement, classified as
eccentric phase, but also called deceleration, yielding,
counter movement. phase increases muscle spindle
activity by pre stretching the muscle before activation
