Verrelst R, et al. - Using data from healthy 89 female physical education students aged 19.53 ± 1.07 years, researchers prospectively investigated hip strength related risk factors contributing to the development of lower extremity (LE) injury. They conducted this study in the institution of the University of Ghent. They found that, LE injury was remarkably predicted by decreased average power (AP) of the hip external rotator (ER) muscles, however, no predictive ability was shown by any of the hip abduction weakness or peak torque parameters. More challenged LE extremity movements might be seen in a dynamic measure such as AP than in a point measure such as peak torque owing to the fact that controlling LE extremity movements is an important function of the hip muscles. Therefore, concentric AP of hip ER muscles can be seen as an interesting factor to include in LE injury screening protocols.
