Not exact matches
It may be argued that by
performing exercises in this manner one misses the benefit of a rapid
eccentric contraction, but a healthy athlete with a slightly reduced training effect always beats an injured athlete with any training effect.
Keeping in mind that the
eccentric portion (when the prime mover is stretching or lengthening) should be
performed slower, and
contraction performed explosively, to maximize strength and muscle building.
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.
Yet, force is greater than expected when isometric
contractions are
performed after
eccentric contractions.
The greatest difference in strength - favoring
eccentric contractions is seen when both
eccentric and concentric
contractions are
performed at a high velocity.
This greater stiffness of the passive elements may therefore allow for greater energy absorption (Kay et al. 2016) during
eccentric contractions, such as those
performed by the hamstrings during sprinting.
