Basketball is a popular sport worldwide that requires a high level of physical ability, coordination, and speed. However, due to sudden movements and jumps, basketball players are often exposed to injuries, especially in the lower extremities. Injuries to the lower extremities that occur in professional basketball can result in a basketball player being absent from the court, which is not desirable during major competitions as a high number of injuries in a team signifies a lack or absence of results. It is extremely important to include preventive programs for the most common lower extremity injuries as well as for general injuries that can occur.
