However, an understanding of modifiable and nonmodifiable factors that influence BOG is lacking, which limits the development of corrective strategies.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n To determine if BOG varies by sex and running speed and the influence of running kinematics and anthropometrics on BOG.<\/jats:p>\n <\/jats:sec>\n \n Design<\/jats:title>\n Cross-sectional study.<\/jats:p>\n <\/jats:sec>\n \n Setting<\/jats:title>\n Record review of routinely collected performance data from a National Collegiate Athletic Association Division I intercollegiate athletic program.<\/jats:p>\n <\/jats:sec>\n \n Patients or Other Participants<\/jats:title>\n A total of 166 Division I collegiate athletes (basketball, cross-country, football, soccer).<\/jats:p>\n <\/jats:sec>\n \n Main Outcome Measure(s)<\/jats:title>\n Running biomechanics (N = 166) and dual-energy x-ray absorptiometry-derived anthropometric data (n = 68) were extracted. Running variables were BOG, step rate, stride length, foot-inclination angle, center-of-mass vertical displacement, heel-to-center of mass anteroposterior distance, and peak stance-phase angles: hip flexion, hip adduction, pelvic drop, knee flexion, and ankle dorsiflexion. Extracted anthropometric variables were height; leg, femur, and tibia length; and anterior-superior iliac spine, hip-joint, and greater trochanter width. We calculated linear mixed-effects models to assess the influence of sex and running speed on BOG and identify the kinematic and anthropometric variables most associated with BOG.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n A significant interaction between sex and running speed on BOG was observed, with males demonstrating a smaller BOG than females at faster speeds and BOG decreasing overall with speed. The kinematic measures most associated with BOG at preferred running speed were foot-inclination angle at initial contact and peak stance-phase hip adduction and ankle dorsiflexion. Anterior-superior iliac spine width was the anthropometric variable most associated with BOG at preferred running speed.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Sex and running speed must be considered when determining the appropriateness of an individual's BOG. Additionally, BOG was associated with several potentially modifiable kinematic parameters.<\/jats:p>\n
