0 used to describe a type of muscle that is used for sudden, fast movements such as sprinting (= running fast over short distances): --
This does not mean that athletes with lower fast-twitch fiber can not jump higher, but they tend to do it a little slower and with a deeper knee bend.
The power of the bending motion comes from fast-twitch muscle fibers located in the central region of the fish.
In this path, a fast motoneuron can convert any muscle fiber into a fast-twitch muscle fiber.
The 90% number signals that there has been a significant change in the recruitment of the fast-twitch muscle fibers.
Chronaxie varies across different types of tissue: fast-twitch muscles have a lower chronaxie, slow-twitch muscles have a higher one.
The latter two losses are dependent on the type of exercise and the type of muscle fibers being used (fast-twitch or slow-twitch).
He did not run very much, but this is rather typical of people with fast-twitch muscle fibers - they rely on short bursts of speed.
At higher loads, the muscle will recruit all muscle fibres possible, both anaerobic (fast-twitch) and aerobic (slow-twitch), in order to generate the most force.
