Cards

Term
stretch shortening cycle (SSC)
Definition
the coupling of an eccentric action with a concentric action; links sprinting, jumping, and changing direction
Term
mechanical model
Definition
describes contractile and noncontractile elements
Term
neuromuscular model
Definition
suggests that preactivation of a muscle or muscle group is partially responsible for the force and power potentiation during the concentric phase of a SSC
Term
contractile elements
Definition
contained within the sarcomere of a muscle; consist of actin and myosin
Term
noncontractile elements
Definition
consist of the series elastic component (SEC), also known as the muscle-tendon unit, and the parallel elastic component (PEC)
Term
muscle spindles
Definition
contain several intrafusal fibers that are arranged in parallel with extrafusal fibers; they provide information regarding muscle length
Term
golgi tendon organs (GTOs)
Definition
located in the muscle-tendon complex and monitor tension; this provides an inhibitory reflex on motor neurons of the agonist muscle
Term
reciprocal innervation
Definition
relfexes that stimulte agonists while simultaneously inhibiting antagonists
Term
plyometric exercises
Definition
include activities such as jumping, landing, hopping, leaping, bounding, galloping, and skipping
Term
jump
Definition
involves a takeoff from one or both feet and a landing on both feet simultaneously
Term
leap
Definition
occurs from taking off on one foot and landing on the other
Term
hop
Definition
when the takeoff and landing occur on the same single foot
Term

galloping and shuffling

Definition
a combination of a step and a leap
Term
skipping
Definition
requires combining a step with a hop
Term
throwing
Definition
when an overhead movement is used to propel an object
Term
toss
Definition
when an underhand action is employed to propel an object
Term
core exercises
Definition
classified as stability, anterior-posterior flexion and extension, rotation, and lateral flexion and extension
Term
three phases of plyometric exercise
Definition

eccentric (loading)

amortization (transition)

concentric (unloading)
