Different hip muscles men and women use for soccer kicks affect ACL injury risk

Robert H. Brophy

Data have revealed that during the two most common soccer kicks, the instep and side-foot kicks, men activate different hip and leg muscles than women do, which may explain why women soccer players are more than twice as likely as men to suffer ACL injuries.

The data were obtained for a study published in the Journal of Bone and Joint Surgery. In it, Robert H. Brophy, MD, of Washington University School of Medicine in St. Louis, and colleagues analyzed the kicking motion in 13 male and 12 female college soccer players using special sensors and video cameras. This approach to studying lower extremity muscles provided new information that furthers the understanding of gender-based variations in athletes, particularly soccer players, according to an American Academy of Orthopaedic Surgeons press release.
