Sentences with phrase «fiber length increases»

A study performed on rats showed that the pelvic floor muscle fiber length increases between 21 - 37 % and the quantity of extracellular collagen matrix increases by 140 % in the pelvic floor muscles.

It's an average length and made with graphite fibers in the frame to increase control, flexibility, and durability as well.

Then, all of the hard work is for nothing, with significant reductions in muscle fiber length and potential increases in injury risk.

Thus, increasing muscle fascicle length will mean that you record a lower value of stiffness, even if the individual muscle fibers are themselves now made of stiffer material.

Muscle fascicle length increases more after eccentric training than after concentric training (Ema et al. 2016), probably through a larger increase in the number of sarcomeres in series within the myofibrils of a muscle fiber (Brughelli & Cronin, 2007; Butterfield, 2012).

Such adaptations include shifts in muscle fiber type, alterations in fascicle length and pennation angle, and alterations in factors at the extracellular and cellular level affecting specific tension, which cause an increase in the strength - to - size ratio.

Factors that shift the angle of peak torque to longer muscle lengths after normal strength training include increases in neural drive at long muscle lengths, increases in normalized fiber length, specific gains in regional muscle size, and increases in muscle stiffness.

Factors that shift the angle of peak torque to shorter muscle lengths after normal strength training include increases in neural drive at short muscle lengths, decreases in normalized fiber length, specific gains in regional muscle size, and increases in tendon stiffness.

When sarcomeres attempt to reduce length by increasing the amount of actin and myosin filaments that overlap, this produces tensile force within the muscle fiber that ultimately leads to muscle contractions.

This change in the optimal length at which torque is developed appears to occur because of an increase in length of the individual muscle fibers (sarcomerogenesis).

Currently, it is thought that muscle strains are produced when the energy absorbed during an eccentric contraction is greater than the muscle fibers can handle, but whether increased fascicle lengths enable greater energy to be absorbed is unclear.

This reduces the effective contractile length of muscle fibers, reducing the shortening velocity, and increasing force production (Erskine et al. 2011).
