What type of muscle fibers used in strength training?
imcomplitory muscle fibers
Twitch muscle fibers are used for prolonged activity and have?
____ twitch muscle fibers are used for prolonged activity and have ___ mitochodria. Slow; many
What is the difference between fast twitch and slow twitch muscle fibers?
Fast twitch muscle fibers are Type II muscle fibers. These muscle fibers have high explosive power and are anaerobic. They have a fast contractile speed and can reach peak tension in 50ms. They have a high glycolytic capacity and have low to moderate resistance to fatigue. Their motor unit strength is high.Slow twitch muscle fibers are Type I muscle fibers. These muscle fibers have steady power and are aerobic. The have a slow contractile speed and needs 110ms to reach peak tension. They have a low glycolytic capacity and a high resistance to fatigue. Their motor unit strength is low.
Which type of muscle fiber has a large quantity of glycogen and mainly used glycolysis to synthesize ATP?
white fast twitch fibers
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 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,...
The word used in muscle names that means diagonal to the midline is?
Oblique fibers
What exercise best represents the use of red muscle fibers?
Basically the time under stress brings in red muscle or the slow twitch fibers into action. If the movement is controlled and the set goes longer the red fibers are used.. If the movement is explosive and heavy then the white fibers are used. For example squatting for 15 rep range incorporates red fibers of the thighs very well
What skeletal muscle fibers that are used for endurance activities have a large quantity of a-creatine-phosphate b-glycogen c-mitochondria d-anaerobic enzymes c-stored APT?
The creatine phosphokinase is the skeletal muscle fibers that are used for endurance activities.
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.
When a muscle is not used and it grows smaller that is called?
Disuse of a muscle causes atrophy, which is a shrinking of muscle fibers leading to weakness. With use, the atrophy can be reversed.
What are the 7 criteria that are used in naming muscles?
Action of the muscle Shape of the muscle Location of the muscle's origin and or insertion Number of origins Location of muscle relative to a bone or body region Direction in which the muscle fibers run relative to some imaginary line Relative size of the muscle
