Stretching is essential for preventing injuries in athletes as it increases flexibility and range of motion. Proper stretching prepares muscles for activity by promoting blood flow and reducing stiffness. Dynamic stretches before exercise can activate muscles, while static stretches post-exercise help in recovery and muscle relaxation. Stretching also enhances overall athletic performance, allowing for smoother movements and better coordination. Regular stretching routines can decrease muscle soreness and the risk of strains, contributing to an athlete's long-term health and performance longevity.
