Why is a light dynamic warm-up recommended before stretching?

• A. It reduces blood flow
• B. It increases tissue temperature, improves muscle elasticity, and primes the nervous system for stretching
• C. It makes muscles stiffer
• D. It is optional and not beneficial

Answer: (B)

Light dynamic warm-up raises tissue temperature and increases blood flow, which makes muscles and connective tissues more pliable and ready for movement. As temperature and circulation rise, the muscles’ viscoelastic properties improve, so they stretch more safely with less resistance. It also primes the nervous system—enhancing neuromuscular activation and stretch tolerance—so you can perform stretches effectively and with reduced risk of injury. Thinking that this would make muscles stiffer or that it’s optional ignores the evidence: warming up prepares both the body and the nervous system for stretching, whereas not warming up or introducing factors that reduce blood flow would make stretching less safe and less effective.
