The purpose of warm-ups before a sports event is to prepare the body for physical activity and reduce the risk of injuries. Warm-ups typically include light aerobic exercises, dynamic stretches, and sport-specific movements that increase heart rate and blood flow to muscles. This process enhances flexibility and coordination, making athletes more agile for competition. Additionally, warm-ups help athletes mentally prepare by focusing on their game strategies. Proper warm-ups can significantly improve performance and ensure athletes are ready to compete at their best levels.
