Sentences with phrase «eccentric muscle activity»

Known as «delayed onset muscle soreness» (DOMS), we typically experience these pains when eccentric muscle activity is involved and the contracting muscles are forcibly lengthened.1 This mechanical stress triggers an inflammatory response and the production of reactive oxygen species (ROS).

Not exact matches

There are 3 phases of muscle activity when doing an exercise: concentric (when the muscle shortens), isometric (when the muscle is static and held in place under tension) and eccentric (when the muscle lengthens).

During the leg press with low foot placement, both narrow and wide stances produced superior gastrocnemius muscle activity during the concentric portion compared to the eccentric portion.

Comparing the face - pull exercise, the researchers found no difference in trapezius muscle activity during the concentric or eccentric phases.

In contrast, there was no difference in gastrocnemius muscle activity between the concentric and eccentric phases when performing the narrow stance high foot placement.

In contrast, with the same absolute load (load lifted in both movements equal to 90 % of overhead squat), there was no difference in gastrocnemius muscle activity during the concentric phase yet greater muscle activity during the eccentric phase when performing the overhead squat.

During the eccentric phase, both the medial and lateral gastrocnemius displayed superior muscle activity during the lock - out and mid-range, compared to the lift - off position.

In agreement, Reid et al. (2011) compared eccentric plantar flexion with the knee fully extended and during a flexed position and reported superior gastrocnemius muscle activity during plantar flexion with full knee extension and no difference in soleus muscle activity.

However, upper trapezius muscle activity during the eccentric portion was superior during the 200 % compared to all conditions, as well as superior muscle activity during the 100 % condition compared with the 50 % condition.

No difference in muscle activity in the eccentric phase existed.

The eccentric component of muscular activity leads to much greater muscle damage / homeostatic disruption than the concentric aspect (which, just as an aside, might be why swimming doesn't tend to lead to significant soreness or conspicuous muscle development).

Stretching won't effect muscle elasticity during eccentric activities which is when most injury occurs.

Effect of eccentric and concentric muscle conditioning on tension and electrical activity of human muscle.

Sandhu et al. (2008) found that the triceps muscle activity was only greater during the eccentric rather than concentric portion of the press up with the hands on a swiss ball compared to on a bench.

Furthermore, Van den Tillaar & Ettema (2009) found that the anterior deltoid muscle activity increased more substantially from the eccentric action to the pre-sticking period of the concentric action in successful compared with unsuccessful 1RM attempts.

The researchers recorded a little more electrical activity in the muscles during both the concentric and eccentric movements.
