Explanation:
There are three types of skeletal muscles in the body
Slow oxidative muscles have a high supply of oxygen and use aerobic respiration, contain a high supply of myoglobin; use triglycerides as the main supply of fuel and fatigue very slowly, have a low contractile velocity and break down ATP slowlyThey have a small muscle fiber diameter and therefore produce a low contractile forceSlow oxidative muscles are used mainly in long-distance activities such as running a marathonThey are found in places in the body that require a great deal of support, such as back and upper legsFast oxidative muscles use aerobic respiration and contain a high amount of oxygen, myoglobin and mitochondria, but they break down ATP quickly and therefore contract quicklyThey have a medium diameter, which means that that the contraction force is greater than in slow oxidative musclesThe main fuel source is glycogenFast oxidative muscles fatigue a bit more quickly then slow oxidative and are used in middle distance events, such as running or swimming Fast glycolytic fibers primarily use anaerobic glycolysis as their ATP sourceThey have a large diameter and possess large volumes of glycogen which is used in glycolysis to generate ATP quicklyFast glycolytic fibers fatigue quickly, permitting them to only be used for short periodsSo,during sprint skeletal muscles follow the order as: There are three types of skeletal muscles in the body
