What is the purpose of a cool-down after exercise?

The purpose of a cool-down after exercise is to prevent dizziness and aid recovery. This phase of physical activity is essential for gradually lowering the heart rate and allowing the body to transition safely from the heightened state of exertion back to a resting state. During intense physical activities, blood can pool in the muscles being used, and a proper cool-down helps to maintain blood flow, preventing issues such as dizziness or faintness as the body adjusts.

Additionally, the cool-down period supports the body's recovery processes, helping to reduce muscle stiffness and soreness that might occur after vigorous exercise. It promotes a steady return to baseline physiological conditions, thereby minimizing the risk of complications associated with abrupt cessation of activity.

The other options do not align with the benefits of a proper cool-down. Keeping the heart rate elevated is contrary to the goal of a cool-down, while promoting muscle soreness and increasing the risk of injury directly oppose the intention to recover and stabilize the body post-exercise.
