Muscles that are better at providing long term physical activity
Muscle fibers when cooked are dark meat.
slow-twitch muscle fibers
There are two broad types of voluntary muscle fibers: slow twitch and fast twitch. Slow twitch fibers contract for long periods of time but with little force while fast twitch fibers contract quickly and powerfully but fatigue very rapidly.
The three type of muscle fibers are fast-twitch, slow-twitch, and hybrid.
Fast muscle fibers have the greater metabolic activity and have the higher concentration of catalase enzyme.
Type I (red) muscle fibers, which have slow oxidative characteristics, are those primarily called on for long-distance running. These are more commonly referred to as 'slow-twitch' muscle fibers.
____ twitch muscle fibers are used for prolonged activity and have ___ mitochodria. Slow; many
Slow oxidative fibers Fast oxidative-glycolytic fibers Fast glycolytic fibers
A combination of both depending on duration and intensity.
are very resistant to fatigue
no, within your muscles are slow and quick twitch muscle fibers, activities such as running and walking use quick twitch muscle fibers while swimming uses slow twitch muscle fibers
One that isn't needed for precise movement. Muscles that need precise control have motor units with more muscle fibers.
