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.
