Tennis elbow, or lateral epicondylitis, is a common overuse injury affecting approximately 50% of regular tennis players at some point in their careers. It is caused by repetitive stress on the forearm tendons, leading to inflammation and pain around the outer elbow. Studies show that players over 40 years old and those who frequently use stiff racquets and high-tension polyester strings are at a higher risk. To prevent tennis elbow, players should focus on proper technique, strength training, and equipment adjustments. Research indicates that using a racquet with a lower stiffness rating (below 65 RA), combined with multifilament or natural gut strings at lower tension (50-54 lbs), can reduce impact forces by up to 30%. Additionally, incorporating forearm strengthening exercises (such as wrist curls and reverse curls) can decrease the risk by 60%. Finally, wearing a properly fitted elbow brace and ensuring adequate rest and recovery are key to avoiding long-term damage. By combining the right equipment with proper conditioning, players can minimize strain and stay on the court pain-free.
