The combination of these angles leads to a contraction of the hamstrings at moderate - to - long muscle lengths, although obviously the important eccentric contraction of the hamstrings that occurs in the swing phase is at fairly long muscle lengths (Nagano et al. 2014)

Not exact matches

In contrast, Pilates emphasizes short reps focused on perfect form and the «eccentric» contraction of the muscle.

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).

Overexpression of Galgt2 in skeletal muscle prevents injury resulting from eccentric contractions in both mdx and wild - type mice.

Most people underestimate the importance of eccentric training because they don't know that there is more mechanical load per motor unit during the eccentric phase of an exercise, and the reason for this is that eccentric contraction involves fewer motor units.

An eccentric muscle contraction is generated when the fibers of the given muscle lengthen as they lower a load, which is often referred to as the down phase of the movement.

Multiple studies have found that eccentric contractions are an untapped source of insane muscle growth.

Eccentric contractions are much more challenging on the muscle and so should be used in the late stages of rehabilitation only.

There are two types of isotonic muscle contraction - Concentric and Eccentric.

So, the next time you train arms, target one of the exercises to lengthen the eccentric contraction.

A plyometric exercise is one that has an explosive concentric contraction (shortening of the muscle) preceded by an eccentric contraction (lengthening of muscle).

They also state that the goal of plyometric training should be to decrease the time needed between the eccentric muscle contraction and the «initiation of the overcoming concentric contraction.»

While all kinds of muscular contraction can cause soreness, eccentric contraction — where the muscle lengthens as it contracts — most often leads to DOMS, according to Mike.

Through 30s intervals of both compound and isolation movements, as well as rotation through focusing on eccentric, concentric, and isometric contractions, he designs training sessions that improve blood flow, strengthen connective tissue, and, of course, bulid muscle endurance in weak areas.

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.

Increasing muscle fascicle length through eccentric training could therefore be a valuable method for improving athletic performance in movements that have peak contractions at long muscle lengths, such as the terminal swing phase of sprinting, or the ground contact phase of sharp change of direction (COD) maneuvers.

And studies using functional MRI measures have shown that the amount of cortical brain area used is greater during eccentric contractions than in concentric contractions (Yao et al. 2014), while functional connectivity between the primary motor cortex and other parts of the brain is reduced (Yao et al. 2016).

And titin seems to be responsible for many of the unique behaviors of eccentric contractions, including residual force enhancement (Shalabi et al. 2016).

Some researchers have proposed that it could occur because of differences in the activation of different regions of a muscle between lengthening and shortening contractions (Hedayatpour & Falla, 2012), although the exact nature of the differences in neural control between eccentric and concentric muscle actions is unclear (Duchateau & Enoka, 2016).

Therefore, high - velocity strength may be more relevant than rate of force development in concentric contractions, compared to in isometric and eccentric contractions.

• 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.

An eccentric contraction is the lengthening of the muscle under load.

The underlying mechanism of the SSC is, that during the lengthening or eccentric contraction the muscle and tendons can store energy, often named as «elastic energy», and this energy can be released during the shortening or concentric contraction.

The 3 stages of contraction are Eccentric, Isometric, and Concentric.

Eccentric - specific gains produced by neural mechanisms might not transfer well to COD ability, because of differences between the strength training exercise and the COD maneuver in terms of both movement pattern, and contraction velocity.

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.

Although it is not well - known, strength training produces adaptations in the endomysium or extracellular matrix of the muscle fiber (Jakobsen et al. 2016), and it is possible that eccentric training could lead to greater changes in the collagen content of muscles than similar concentric contractions (Heinemeier et al. 2007; Holm et al. 2017), which could in turn alter the properties of the passive elements that underpin eccentric - specific strength.

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.

An example of an eccentric contraction is the downward phase of a biceps curl where your arms return to the resting position as you lower the weight in a controlled manner.

Since this is about primal - what is the primal justification for having more strength in eccentric phase of muscle contraction?

I just realized I had the wrong idea of what and eccentric contraction is, so nevermind the examples on the last paragraph.

«Eccentric training has been shown to produce greater muscle hypertrophy than concentric training as a result of greater ability for maximal force generating capacity during eccentric contractionEccentric training has been shown to produce greater muscle hypertrophy than concentric training as a result of greater ability for maximal force generating capacity during eccentric contractioneccentric contractions.»

Superslow encompasses the idea of slow and measured concentric and eccentric contractions.

It therefore showed that the aspects of an exercise that determine transfer to sport are not limited to the movement pattern, but include other factors such as the muscle group being trained (the hamstrings are key to sprinting ability), and the mode of the contraction (eccentric muscle actions are very important during sprinting).

When you train using only concentric and eccentric muscle contractions without out pausing at the end range of a movement (exercise) when the desired muscle is fully contracted, your joints don't get strong and stable at the end range of motion.

Although it is not often discussed, it is possible that eccentric training could lead to greater changes in the collagen content of muscles than similar concentric contractions (Heinemeier et al. 2007; Holm et al. 2017), which could in turn alter the properties of the passive elements that underpin eccentric - specific strength.

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.

Maybe we even got like mocji can put it to where like it will resist you so much that you're pretty much just doing like a max effort isometric contraction and you can program it to only have resistance when you're going to the negative portion of the lift or only have resistance when you're going to the positive effort of the lift and there's no eccentric contraction involve.
