A dynamic warm-up is known to increase which physiological factors?

• A. Delays heart rate increase
• B. Decreases blood flow to muscles
• C. Reduces range of motion
• D. Increases muscle temperature, mobility, and nerve conduction.

Answer: (D)

Dynamic warm-ups prepare the body by raising muscle temperature, increasing blood flow to active muscles, and speeding up nerve conduction. These changes make muscles more pliable, joints more mobile, and neural signals travel faster, so you get higher muscle temperature, greater mobility, and faster nerve conduction. That description best captures what a dynamic warm-up achieves. It doesn’t delay heart rate, decrease blood flow to muscles, or reduce range of motion—the opposite of what actually happens.
