Fast-twitch fibers are the most vulnerable to denervation and then reinnervation by slow-twitch motor neurons [22].
When the frequency is set within the muscle fiber fast-twitch frequency, the mechanical energy content of the vibration input plus the contraction energy of fast-twitch fibers will be exerted on the bone.
Fast-twitch fibers contract faster and more explosively than other muscle fibers, giving a racehorse power to gain speed quickly.
7] This is in contrast to other evidence that suggests that fast-twitch fibers in the thyroarytenoid and lateral cricoarytenoid muscles are reinnervated more rapidly and to a greater degree than slow-twitch fibers.
The fast-twitch fibers contract more forcefully than the slow-twitch but have no blood supply and can only fire for a relatively short period of time before fatiguing from physiologic acidic (lactic) build-up and adenosine tri-phosphate (ATP) depletion.
We will simply refer to them as slow-twitch and fast-twitch fibers.
The machines, originally designed for use in rehabilitating injuries, train the fast-twitch fibers in the muscle and relieve any strain normal training would put on muscles and joints.
Skeletal muscles are a mix of slow-twitch fibers, designed to resist fatigue, and fast-twitch fibers, which enable intense periods of work.
Generally, slow-twitch muscle fibers have greater oxidative metabolism and fast-twitch fibers have greater glycolytic metabolism.
Fast-twitch fibers don't depend on oxygen for energy.
