What kind of muscle tissue has the most mitochondria in it?
Type I muscle fibers
What type of muscle is rich in ATP?
Muscle fibers are rich in ATP. All muscle fiber types are rich in ATP (having many mitochondria).
How many mitochondria are there in skeletal muscle?
It depends on the type of skeletal muscle. Slow and fast oxidative fibers (type I and type IIa) may have many mitochondria. Fast glycolytic fibers (type IIx/IIb) have very few mitochondria. This is because in fast glycolytic fibers (type IIx/IIb) ATP can be produced outside of the mitochondrion in the cytosol of the cell due to high concentrations of glycolytic enzymes present in these fibers. In contrast, in oxidative fibers ATP is produced mostly within the mitochondrion, so more mitochondria are needed to to produce large amounts of ATP. Also, the number of mitochondria in these cells can increase with adaptations to exercise conditioning.
What type of muscle fibers are there?
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.
What type of muscle fibers used in strength training?
imcomplitory muscle fibers
Are Type II muscle fibers aerobic?
FALSE
What type of muscle fibers you need to develop for weight lifting competition?
Mary needs to develop her fast muscle fibers. In order to do this, she will need to have frequent, brief and intensive workouts. She also needs to create muscle hypertrophy which will create an enlargement of the stimulated muscle. She can gain this by repeated and exhaustive stimulation which will create more mitochondria.
What type of embryological cell gives rise to muscle fibers?
What type of embryological cell gives rise to muscle fibers
Activities such as swimming and running are most likely to stimulate development of what type of muscle fibers?
Slow, fatigue-resistant fibers
What muscle fiber type typically constitutes the largest percentage of the total muscle fibers in most human muscles?
Skeletal muscles are the largest percentage of total muscle fibers in the human body.
What is a fast fiber?
A Fast Oxidative Fiber is a type of muscle fiber with many mitochondria and capillaries. This type has a high myoglobin content. This type of muscle tires more quickly than the slow oxidative fibers and is an intermediate sized muscle. This muscle is good for sprinting and other short, fast-paced activities.
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.
