**Question:**

Fast twitch fibers are

- ○ Rely on oxygen
- ● Fatigue faster and are best suited for activities requiring short bursts of power and energy
- ○ Best used for long distance running, swimming, or cycling
- ○ None of the above

**Explanation:**

Fast twitch fibers are muscle fibers that fatigue more quickly and are ideally suited for activities that involve short bursts of power and energy, such as sprinting or weightlifting. Unlike slow twitch fibers, they don't rely heavily on oxygen and are less suited for endurance activities such as long-distance running, swimming, or cycling.
