The significance of a cool-down period after exercise lies in its ability to facilitate recovery and prevent injury. During this phase, heart rate and blood pressure gradually return to normal levels, reducing the risk of dizziness or fainting. A cool-down also aids in clearing metabolic waste products from muscles, minimizing soreness and stiffness. Incorporating stretching during this period enhances flexibility and can improve overall performance in future training sessions. Thus, a proper cool-down is essential for comprehensive fitness and recovery.
