Dynamic stretching is used to practice and refine motor skills and prime the motor system.

• A. Practice and refine motor skills, priming the motor system
• B. Hold static positions
• C. Cool down
• D. Increase passive stiffness

Answer: (A)

Dynamic stretching prepares the body by actively moving joints through their full range of motion, which allows you to rehearse movement patterns and wake up the neuromuscular system. By actively engaging muscles and tendons in sport- or task-specific motions, you improve coordination, timing, and motorUnit recruitment, so your movements become smoother and more controlled when the main activity begins. The process also raises body temperature and enhances neural activation, helping the nervous system respond more quickly and efficiently during performance. That combination—practice of movement patterns plus neuromuscular priming—is why dynamic stretching is used to refine motor skills and ready the motor system.

Holding static positions doesn’t train movement patterns or prime neuromuscular control in the same way; it’s more about flexibility and is often used after activity. Cooling down serves recovery after exertion, not pre-performance preparation. Increasing passive stiffness would hinder quick, elastic movements, which runs counter to what dynamic stretching aims to achieve.
