Warm-up exercises are significant for injury prevention as they prepare the body for physical activity. Warming up increases blood flow to the muscles, enhancing flexibility and reducing stiffness, which can lower the risk of strains and sprains. It also helps to gradually elevate the heart rate, preparing the cardiovascular system for more intense activity. Additionally, a structured warm-up routine can improve overall performance by activating relevant muscle groups and enhancing coordination. Neglecting this practice may increase the likelihood of injuries during workouts or sports.
