• Takes advantage of the stretch shortening cycle → Uses energy stored
by eccentric muscle contraction (lengthening phase) quickly followed by concentric muscle contraction (shortening phase) to generate high amounts of power.
Not exact matches
This loads the leg
by rapidly forcing its
muscles to stretch and undergo rapid
eccentric contraction (Just think of compressing the coils of a strong and stiff spring).
The downward phase of a push - up involves an
eccentric contraction of the chest
muscles, which is immediately followed
by a strong concentric
contraction to push back up and clap the hands.
A plyometric exercise is one that has an explosive concentric
contraction (shortening of the
muscle) preceded
by an
eccentric contraction (lengthening of
muscle).
During the stretch - shortening cycle a
muscle gets stretched or lengthened (
eccentric contraction), followed
by an instant shortening (concentric
contraction).
Eccentric - specific gains produced
by peripheral mechanisms might be reasonably expected to transfer well to COD ability, because the stiffness of the passive elements within the
muscle is not expected to be affected
by the movement pattern, and may actually be increased
by the velocity of the
contraction (Rehorn et al. 2014), making the properties of the passive elements even more relevant for high - velocity
contractions, than for low - velocity
contractions.
Over the past several decades, numerous studies have established that
eccentric contractions can maximize the force exerted and the work performed
by muscle... that they can attenuate the mechanical effects of impact forces; and that they enhance the [good] tissue damage associated with exercise.
