Sentences with phrase «twitch fibers require»

In order to be fully developed, slow - twitch fibers require to be put under tension for extended periods of time.

Not exact matches

Instead, it appears to be related to a much more fundamental metabolic constraint: the length of time required for the animal to reach its theoretical maximum speed, based on the number of «fast twitch» muscle fiber cells in the creature's muscles, as compared to the length of time it takes for those cells to run out of readily available energy.

This type of training demands high strength levels but doesn't require much endurance, which forces to body to use the fast - twitch muscle fibers.

This type of training doesn't require a lot of strength, but it does require endurance and mainly uses the slow - twitch fibers, but neglects the fast - twitch type.

In contrast, activities that require muscle endurance mainly target slow - twitch, or type 2 muscle fibers, those optimized for sustained activity.

Those with an abundance of slow twitch fibers would include athletes such as runners, cyclists, and swimmers, as those activities require intense aerobic activity.

Working on peak power output will help to improve your fast - twitch muscle fiber recruitment which plays a huge role in all athletic endeavors that require speed and power.

Others are more inclined to activities that require speed and intense bursts of power, traits which are equated with more fast - twitch fibers.

Running at a faster pace activates Slow Twitch + Fast Twitch A fibers because running faster requires more force to be generated.

Very fast running (i.e. intervals and sprints) and fast or steep uphill running activate the Slow Twitch + Fast Twitch A + Fast Twitch B fibers due to the high level of force required to run at very fast paces.

It requires the most energy and effort to activate the largest of the fast twitch fibers so it seems reasonable and most effective to me to train those fibers when your energy levels are the highest, enabling the heaviest weight to be lifted and training the highest number of fibers.

It requires a lot more energy and does a lot more damage doing say, 10 × 10 (or your 15 × 5), than it does doing one set of 25 - 50 or 50 - 100 reps.. In the end, you get less hypertrophy with high volume heavy lifting, because a) you still have all that myostatin buildup from heavy lifting suppressing hypertrophy, b) you don't sufficiently fatigue medium and fast twitch fibers, c) you don't get the increased IGF - 1 production and increased protein synthesis that you would get from high reps, and d) because the energy requirements of repairing the damage caused by heavy lifting are too high.

For example, running at a slow pace activates only Slow Twitch fibers because the force required to run slowly is small enough that the Slow Twitch fibers are strong enough to handle the job themselves.

If you pick up a heavy weight then both Slow Twitch + Fast Twitch A fibers will be activated because more force is required to lift the weight.

Low weight and a large number of reps will typically only need to recruit the type I slow twitch fibers, while heavier weights and greater intensity requires adding in the Type IIA and IIB faster twitch fibers.
