Final answer:
The purpose of the final cool down phase of an aerobic exercise session is to reduce heart rate and blood pressure, increase muscle flexibility, and improve recovery time.
Step-by-step explanation:
The purpose of the final cool down phase of an aerobic exercise session is to reduce heart rate and blood pressure, increase muscle flexibility, and improve recovery time. When you engage in aerobic exercise, your heart rate and blood pressure increase. Cooling down after exercise allows your body to gradually return to its resting state, helping to reduce heart rate and blood pressure. Additionally, cooling down includes stretching exercises that help to improve muscle flexibility, reducing the risk of injury. Finally, a cool down period helps improve recovery time by allowing your body to gradually transition from the intense exercise to a more relaxed state, reducing muscle soreness and promoting the removal of metabolic waste products.
