What type of fibers are present in supraspinatus and infraspinatus muscles?
The supraspinatus muscle contains mostly type I (slow-twitch) muscle fibers, which are more fatigue-resistant and used for sustained contractions. The infraspinatus muscle contains a mix of type I and type II (fast-twitch) muscle fibers, which are used for more powerful and quick contractions.
What type of muscle fibers are found in higher proportion in weight lifters?
Type II (fast-twitch) muscle fibers are found in higher proportion in weight lifters. These fibers generate more force and are associated with explosive movements and short bursts of intense activity.
Does a nerve provided impulses for many muscle fibers or just few?
A nerve can stimulate impulses to several muscle fibers. When muscle fibers are grouped they form a single muscle group like the biceps.
What is it called when white muscle fibers that contract quickly?
Fast-twitch muscle fibers.
Which fibers in the skeletal muscle are stimulated only by the degree of stretch?
Muscle spindles are the fibers in skeletal muscles that are stimulated by the degree of stretch. These specialized sensory organs detect changes in muscle length and contribute to the stretch reflex, helping to maintain posture and control muscle contraction.
What type of muscle fibers used in strength training?
imcomplitory muscle fibers
Are Type II muscle fibers aerobic?
FALSE
What type of embryological cell gives rise to muscle fibers?
What type of embryological cell gives rise to muscle fibers
What are the three types of muscle fibers?
The three type of muscle fibers are fast-twitch, slow-twitch, and hybrid.
What type of muscle fibers does aerobic trainning chiefy work?
ng healthy and working out from besties
What kind of muscle tissue has the most mitochondria in it?
Type I muscle fibers
What type of fibers are present in supraspinatus and infraspinatus muscles?

Which of these is not a way of classifying muscles?
the type of muscle fibers
What type of muscle fibers are found in higher proportion in weight lifters?
Type II (fast-twitch) muscle fibers are found in higher proportion in weight lifters. These fibers generate more force and are associated with explosive movements and short bursts of intense activity.
Which type of muscle tissue is autorhythmic?
cardiac muscle
What type of muscle is a chicken leg?
Cardiac muscle.
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.
