What is the role of slow muscle fibers and fast muscle fibers in the response of a muscle to different types of exercise?
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.
Which turkey meat is made of slow twitch muscle fibers?
Muscle fibers when cooked are dark meat.
What are the three types of muscle fibers?
The three type of muscle fibers are fast-twitch, slow-twitch, and hybrid.
Does slow muscle fibers or fast muscle fibers have a higher catalase concentration?
Fast muscle fibers have the greater metabolic activity and have the higher concentration of catalase enzyme.
Which muscle fibers are best suited for running a marathon?
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.
Why do slow twitch muscle fibers have more mitochondria compared to fast twitch muscle fibers?
Slow twitch muscle fibers have more mitochondria compared to fast twitch muscle fibers because they rely more on aerobic metabolism for energy production, which requires a higher number of mitochondria to generate ATP efficiently.
Twitch muscle fibers are used for prolonged activity and have?
____ twitch muscle fibers are used for prolonged activity and have ___ mitochodria. Slow; many
What are the types of any muscle fiber?
Slow oxidative fibers Fast oxidative-glycolytic fibers Fast glycolytic fibers
Which type of muscle fibers would be utilized for short periods of walking or jogging?
A combination of both depending on duration and intensity.
Can you convert swimming laps into walking steps?
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
What motor unit has the fewest muscle fibers?
One that isn't needed for precise movement. Muscles that need precise control have motor units with more muscle fibers.
What type of muscle fiber are used in long distance running?
Slow twitched fibers. The slow muscles are more efficient at using oxygen to generate more fuel (known as ATP) for continueous, extended muscle contractions over a long period, eg long endurance athletes, triathlon, marathon,...
