Study Notes

Types of Muscles

There are three types of muscles in the body: smooth, cardiac, and skeletal.

Smooth Muscle

Found in internal organs and blood vessels.
Involuntary muscle, meaning it's not under conscious control.

Cardiac Muscle

Found only in the heart.
Involuntary muscle, meaning it's not under conscious control.

Skeletal Muscle

Attached to the skeleton.
Voluntary muscle, meaning it's under conscious control.

Muscle Fibers

Type I Fibers

Needed for endurance activities, such as long-distance cycling.
Muscles are red in color due to the high amount of capillaries transporting oxygenated blood.
Allow muscles to work for a long duration without getting tired.

Type IIx Fibers

Needed for high-intensity, short-duration activities, such as sprinting.
Muscles contract quickly and produce a lot of force.
Muscles tire quickly, limiting the duration of high-intensity activity.
