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.


What are the types of any muscle fiber?

Slow oxidative fibers Fast oxidative-glycolytic fibers Fast glycolytic fibers


When might you use slow-oxidative fiber and when do you use fast-glycolytic fibers?

Slow Oxidative: These muscle fibers twitch at a very slow rate and are very resistant to fatigue. The peak force exerted by these muscles is also very low. Slow muscle fibers have a lot of oxidative enzymes but they are low in ATP activity. Slow oxidative fibers are used for aerobic activities Fast-glycolytic fibers: Some muscle fibers can contract at a fast rate and produce a large peak force while being resistant to tiring even after many cycles. These fibers are have a large ATP activity and are high in oxidative and glycolytic enzymes. These fibers are used for anaerobic activities that need to be sustained over prolonged intervals of time.

Which type of muscle fibers would be utilized for short periods of walking or jogging?

A combination of both depending on duration and intensity.


Which type of fibers are also called red oxidative?

Slow-twitch fibers are also called red oxidative fibers. These fibers are more efficient at using oxygen to generate energy and are suited for activities requiring endurance and sustained low-intensity effort.


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 is the type of muscle that is most resistant to fatigue?

SlowThe slow oxidative muscle fibers are more resistant to fatigue.Cardiac muscle is most resistant to fatigue. Cardiac muscle is constantly working involuntarily to keep us alive by pumping blood through our system. It must be resistant to fatigue for us to be healthy.Intermediate fibers


Which color fibers are slow oxidative fibers?

Slow oxidative fibers are typically red in color due to their high myoglobin content, which gives them their oxidative capacity for sustained contractions over long periods of time.


What are the three muscle fiber types?

Type 1 (slow twitch oxidative) , type 2a (fast twitch oxidative) and type 2b (fast twitch glycolytic).


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,...


Compare slow oxidative to fast glycolytic muscles fibers?

Slow twitch: These muscle fibers are also known as Type 1. Slow twitch muscle fibers are generally fatigue resistant and have a high capacity for aerobic energy supply, but they have limited potential for rapid force development. They are red because all of the blood that goes through them due to their high level capillarizention. They are not easily injured and they can handle extreme amount of work and do not fatigue easily. Slow twitch muscle fibers rely on oxygen as their main energy source. These muscle fibers contract slowly and can be used for longer periods of time before they fatigue. Therefore, slow twitch fibers are great at helping athletes run marathons and bicycle for hours.Fast glycolytic: Fast glycolytic or Type 2b are also fast twitch white muscle fibers but these muscle fibers have a very low tolarance to fatigue and need a high period of recovry after use. However, they are extremely powerful and explosive fibers and are the ones involved in activities like power lifting, the pitch of a baseball, javelin throwing, shot putting, the beginning of a sprint, etc.
