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

The main purpose of a cool-down after exercise is to gradually lower heart rate and improve recovery by promoting circulation. Engaging in a cool-down period allows the body to transition from a state of high activity to rest, helping to prevent cardiovascular complications and dizziness that can arise from abruptly stopping intense physical activity.

During the cool-down, lower-intensity activities, such as walking or gentle stretching, help to maintain blood flow to the muscles, thereby facilitating the removal of metabolic waste products like lactic acid. This process can enhance recovery by mitigating soreness and aiding in muscle repair.

In contrast, abruptly stopping all physical activity can put stress on the cardiovascular system, leading to adverse effects. While muscle growth and anaerobic capacity are important in the context of training adaptations, they are not the primary focus of a cool-down phase; instead, the cool-down primarily serves to stabilize the body's physiological state post-exercise.
