Slow twitch muscle fibers are resistant to what?
are very resistant to fatigue
Activities such as swimming and running are most likely to stimulate development of what type of muscle fibers?
Slow, fatigue-resistant 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
How are fibers used?
Synthetic fibers are used for home decorating purposes. They are easy to wash and dry up quickly. They are stain resistant and resistant to insects.
Inability of muscle fibers to contract after a long period of contraction?
muscle fatigue
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.

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.
What are PVC fibers?
PVC fibers are a form of synthetic fibers that are resistant to acids and bases. They are most commonly used for wigs, doll hair, water beds, and pool toys.
Why is the heart fatigue resistant?
Cardiac muscle is designed to continually work without tiring
What is a physical activity that is short explosive and depends solely on the enegry that is stored in a musle and not on oxygen intake?
You are thinking of muscle fibers types. Skeletal muscle fibers are grossly divided into two type; slow twitch (type I) and fast twitch (type II).Slow twitch fibers are capable of continuous extended contractions and therefore, do not fatigue quickly. Fast twitch fibers are used for short rapid bursts of energy and as such fatigue more quickly than slow twitch fibers.
What fibers are responsible for resistance in tendons?
Collagen Fibers, made up of fibrous protein, which are bundled together into thick collagen fibers. Collagen fibers are extremely tough and provides high tensile strength (which provides resistant property of tendons) Stress tests have show collagen fibers to be stronger than steel fibers of the same size.....EB
