Final answer:
The statement is True as a lack of proper warm-up can lead to a significant percentage of sports injuries. Warm-ups increase blood flow, prepare muscles and tendons for activity, and prevent strains and tendinitis.
Step-by-step explanation:
The statement that more than 30% of sports injuries seen are due to a lack of a warm-up is True. A proper warm-up is critical in preparing the body for physical activity. Warming up gradually increases the intensity of the activity which boosts blood flow to the muscles and elevates the heart rate. Muscles and tendons that are warmed up are less susceptible to injuries. On the other hand, not warming up can lead to strains, which involve the tearing of muscles or tendons, and tendinitis, the irritation of tendons. Both can effectively be prevented by a proper warm-up and stretching routine.
Preventing injuries through warm-up and cool-down exercises is not only easier but also far less painful than treating an injury after it occurs. Additionally, using the correct safety equipment for sport activities, engaging in stretching, proper rest, and recovery, all contribute to reducing the risk of sustaining sports injuries.
