Does gender relate to lower limb asymmetry in adolescent long-distance runners?

Gender differences have been reported for lower extremity running mechanics in healthy and injured adult runners. However, lower extremity asymmetry has been less frequently studied. Uninjured adolescent runners were stratified by gender and side-to-side limb symmetry was measured during the stance phase of running. Females demonstrated greater side-to-side asymmetry in sagittal knee and coronal ankle position than males. Prospective study is warranted to identify if gender asymmetries are related to running related injuries.
