Knee alignment and biomechanics significantly affect athletic performance. Proper alignment ensures that forces are distributed evenly across the joints, reducing the risk of injury and maximizing efficiency. Poor biomechanics can lead to >ineffective movement patterns, resulting in decreased power, speed, and agility as well as increased fatigue. In sports, optimal knee function allows for better force generation during activities like running or jumping. Athletes can benefit from proper training to correct alignment issues and improve their biomechanics, enhancing performance and longevity in their respective sports.
