Fast-twitch fibers can deliver a quick burst of power. Slow-twitch fibers can maintain a contraction for a longer time.
Because of the higher energy demands of slow-twitch fibres (due to their more frequent and prolonged usage) they have a higher density of mitochondria for energy and myoglobin to provide oxygen. Meanwhile, fast-twitch fibres tend to have larger stores of glycogen so that vast quantities of energy can be provided at short notice.
Slow twitch
Fast twitch fibers
Yes Such as in weight traning if you train your fast twitch you will recover faster but fast is more muscle strength not really size if your looking for size in muscles go with slow twitch
I think you are thinking of fast twitch muscles. There are two kinds fast twitch and slow twitch.
fast-twitch NOT slow-twitch
They are different type of muscle fibres (US spelling Fibers). Fast twitch are good at contracting fast but fatigue quickly. Slow twitch contract more slowly but do not fatigue as fast. In athletes, sprinters tend to have a dominance of slow twitch fibres while insurance competitors have a dominance of slow twitch.
Slow twitch and fast twitch A muscle fibers.
slow twitch and fast twitch
Strength and power exercise like weight lifting requires the explosive release of energy yielded by fast-twitch muscle fibers. Slow-twitch muscles are involved in endurance activity.
They tend to have more fast-twitch or slow-twitch fibers, depending on what kind of athlete they are.
Fast twitch muscle fibres are ones used for sudden bursts of physical activity, such as sprinting or weight lifting. Slow twitch muscle fibres meanwhile are designed for extended periods of contraction, such as keeping a person's head supported or maintaining a standing posture. Physiological differences between the two fibres are largely down to their different energy requirements. Slow twitch fibres have more surrounding capillaries, more mitochondria and a larger amount of myoglobin within the muscle (causing them to be red in color). Meanwhile fast twitch fibres have a store of glycogen to provide a quick burst of energy when the muscles come into action.
