MEDICAL PHYSIOLOGY

Detailed explanation-1: -Most muscles are made up of two kinds of muscle fibers that help you move your body: slow-twitch muscle fibers, which move more slowly but help to keep you moving longer. fast-twitch muscle fibers, which help you move faster, but for shorter periods.

Detailed explanation-2: -Fast oxidative muscles, also known as type II-A fast twitch also use aerobic respiration and contain a high amount of oxygen, myoglobin and mitochondria, but they break down ATP quickly and therefore contract quickly.

Detailed explanation-3: -Slow-twitch fibers tend to have a higher quantity of mitochondria, which means that it takes much longer for them to break down the ATP to create energy, allowing your muscle fibers to prolong its energy and power production over longer periods of time.

Detailed explanation-4: -The two types of skeletal muscle fibers are slow-twitch (type I) and fast-twitch (type II). Slow-twitch muscle fibers support long distance endurance activities like marathon running, while fast-twitch muscle fibers support quick, powerful movements such as sprinting or weightlifting.
