Answer:

Explanation:

Muscle is one of the most important tissue of the body that helps in the control and the coordination of the body movements. Three different types of muscle are smooth muscle, cardiac muscle and skeletal muscle.

The red fibers are the slow twitch fibers that contains large amount of stored oxygen in their muscles. These fibers can generate ATP by the fat and the glycogen metabolism. This fiber will help the swimmers to obtain energy at the end of the race to overcome the oxygen deficiency.
