What is the role of a cooldown phase post-exercise?

The primary purpose of a cooldown phase after exercise is to gradually lower heart rate and blood pressure. During exercise, especially intense physical activity, the heart rate and blood pressure increase to supply more oxygen to the muscles and remove metabolic waste. A cooldown phase helps facilitate a smooth transition back to resting levels, which can prevent dizziness, reduce the risk of fainting, and help the circulatory system adapt.

Additionally, a proper cooldown can help in avoiding stiffness and soreness by allowing the body to recover more effectively. It typically involves lighter activity or stretching, but the key factor is the emphasis on letting the heart rate and blood pressure decrease gradually, promoting overall cardiovascular health. While stretching may be a component of a cooldown, the core function remains the progression back to a state of rest.
