1. **Identify Muscle Types**: Understand that there are different types of muscle fibers in the human body, primarily classified into two categories: slow-twitch (red) fibers and fast-twitch (white) fibers.

2. **Focus on Fast Contraction**: The question specifically asks about muscles capable of fast contraction. This indicates a focus on fast-twitch muscle fibers.

3. **Define White Muscle Fibers**: White muscle fibers, also known as fast-twitch fibers, are the type of muscle fibers that are capable of rapid and powerful contractions.
