How do warmups and warmth affect exercise-induced muscle soreness and performance?

• A. Warmups do not affect flexibility.
• B. Warmups and warmth can improve flexibility and reduce stiffness.
• C. Warmups worsen stiffness.
• D. Warmups only affect power, not flexibility.

Answer: (B)

Warmups and warmth raise muscle and tissue temperature, which makes muscles, tendons, and ligaments more pliable. That increased elasticity helps joints move through a larger range of motion with less resistance, so you feel less stiff and can stretch and move more freely. With warmer muscles, nerve signals travel faster and muscles can generate force more efficiently, improving coordination and performance in activities that require speed, power, and dynamic movement. So the result is better flexibility and reduced stiffness at the start of exercise, which often translates to smoother, more efficient performance. Heat after activity can ease lingering stiffness by increasing blood flow and tissue pliability, but it doesn’t prevent the delayed soreness that comes from micro-damage after exercise.
