What is it called when white muscle fibers that contract quickly?
Fast-twitch muscle fibers.
How do you know if you have white or red muscle fibers?
Humans have both in their bodies.
Why are endurance athletes able to exercise longer than non-endurance athletes?
There are basically two types of muscle fibers in our bodies that we have voluntary control over. One is called "red" muscle, and the other is called "white". Red muscle fibers have the ability to perform work over longer periods of time without fatigue. White muscle fibers are able to work hard, but for a shorter period of time than red fibers. An endurance athlete will have exercised his or her red muscle fibers (through long exercise sessions), so that they grow stronger and bigger. This means that their body will have the ability to do work for much longer than a person who only exercises for shorter periods (and exercises their white muscle fibers).
What fiber type of muscle fiber is pink in color?
Pink-colored muscle fibers are typically classified as Type IIa fibers, also known as fast oxidative fibers. These fibers have a moderate resistance to fatigue and are capable of both aerobic and anaerobic energy production. They are well-suited for activities that require both strength and endurance, such as middle-distance running or swimming. The pink color is due to a higher myoglobin content compared to Type IIb fibers, which are more white and primarily anaerobic.
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 is the name given to the large white central expansion that binds the fibers of the internal abdominal oblique muscle to the linea Alba?

What system does White matter refer to myelinated fibers?
White matter refers to the parts of the central nervous system that are primarily composed of myelinated nerve fibers. These fibers are responsible for transmitting information between different areas of the brain and spinal cord. White matter appears white because of the high lipid content of the myelin sheaths.
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 some differences between muscle cell and a white blood cell?
A white blood cell has no nucleus and haemoglobin. They are part of the immune system of the body. They are differentiated into five distinct types based on their shape. Muscle cells are rod shaped and are packed with thin fibers called myofibrils. They are nucleated and have haemoglobin. Muscle cells can contract and expand.
