Twitch is a term used for:

Answer 1

Twitch:

1. Twitch or muscle twitch is a term used for muscle contraction.
2. Most muscles are composed of two types of muscle fibers that aid in movement: slow twitch and quick twitch fibers.

Slow-twitch muscle fibers:

1. Slow-twitch muscle fibers move more slowly yet let you stay active for longer.
2. Slow-twitch muscle fibers are powered by an aerobic energy source.
3. Slow-twitch muscle fibers are resistant to exhaustion and concentrate on modest, sustained motions and postural stability.
4. They have more mitochondria and myoglobin and are more aerobic than fast-twitch fibers.
5. Because of their blood supply, slow-twitch fibers are also known as type I or red fibers.

Fast-twitch muscle fibers:

1. Fast-twitch muscle fibers allow you to move quickly but for a shorter amount of time.
2. Fast-twitch muscle fibers use less blood since they generate their fast source of energy.
3. Fast-twitch muscle fibers produce larger and more strong forces for shorter periods and tire faster.
4. Because they are more anaerobic and have less blood flow, they are also known as white fibers or type II.
