Sentences with phrase «as eccentric contractions»

Not exact matches

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.

In particular eccentric muscular contractions (where the muscle lengthens as it contracts) such as in hopping, bounding and other plyometric exercise, running downhill, squatting and the lowering phase when lifting weights, can cause DOMS.

This helps to develop power in the quadricep muscles (amongst others) as landing into a squat position involves an eccentric contraction of the quads to decrease rapid knee bending, before a concentric contraction to straighten the knees and jump up.

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.

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.

Cal Dietz explains the isometric phase as the energy station that transfers absorbed eccentric energy to explosive concentric contractions.

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.

However, it is important to recognize that when studying lengthening (eccentric) contractions, we observe that the force - velocity relationship is the opposite way around, as can be seen in the chart below.

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.

«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.»

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).

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.
