What is the primary purpose of cool down exercises after physical activity?

The primary purpose of cool down exercises after physical activity is to return the heart rate to normal. During vigorous exercise, the heart rate increases to supply more oxygen to the muscles, and a cool down helps to gradually reduce this heart rate back to its resting level. This gradual decrease is important because it helps prevent dizziness, lightheadedness, and reduces the risk of injury or complications that can arise from abruptly stopping intense physical activity. Cool down exercises also assist in promoting circulation, facilitating recovery, and can help alleviate muscle stiffness and soreness by allowing lactic acid and other metabolic wastes to be cleared from the muscles more effectively.

Other options might focus on aspects related to different phases of exercise; however, they do not address the specific physiological benefits that a cool down provides in terms of heart health and stability following exercise.
