Why is a warm-up important before sport and what should it typically include?

• A. Increases body temperature, elasticity and mental readiness; should include light aerobic work, dynamic stretches and sport-specific drills.
• B. Decreases heart rate and cools muscles; should include heavy lifting.
• C. Only important for flexibility; should include static stretching only.
• D. Not necessary; should start with maximal effort exercise.

Answer: (A)

A warm-up before sport helps prepare both body and mind. It raises core and muscle temperature, which makes muscles more elastic and nerves faster, improving movement efficiency and reducing injury risk. It also increases blood flow and oxygen delivery to working muscles and sharpens focus and readiness.

The best choice includes a progression: light aerobic work to gradually elevate heart rate, dynamic stretches to enhance range of motion and muscle preparedness, and sport-specific drills to rehearse the exact movements you’ll use. This combination primes the body for performance without fatigue from heavy lifting, and avoids static stretching as the sole or primary method, since static stretching before activity can temporarily reduce strength and power. Starting with maximal effort or skipping preparation won’t provide the gradual, targeted preparation your body needs.
