There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue.

They are mainly used for postural maintenance (such has holding the head upright), or endurance exercises (like marathon running).

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.
