What is the primary cause of tennis elbow?

  1. Genetic predisposition

  2. Overuse of lower arm muscles

  3. Improper lifting technique

  4. Injury from a fall

The correct answer is: Overuse of lower arm muscles

Tennis elbow, or lateral epicondylitis, is primarily caused by the overuse of the lower arm muscles, particularly those that extend the wrist and fingers. This repetitive strain leads to microtears in the tendons attached to the elbow, resulting in pain and inflammation. Activities that involve repetitive gripping, wrist extension, and forearm rotation—common in sports like tennis as well as in certain occupational tasks—can significantly stress these muscles and tendons. In this context, factors like genetic predisposition, improper lifting technique, and injury from a fall may contribute to elbow pain or other types of injuries but are not the primary cause of tennis elbow. The specific mechanism of overuse is key to understanding how this condition develops, making it essential for personal trainers and athletes to address proper technique, strength, and conditioning to prevent it.
