Why is this relevant?: It has been hypothesized, that the gluteus maximus has two functionally distinct portions which may be selectively activated depending on the movement pattern. That is, the superior portion of gluteus maximus is more active in motions involving hip abduction, whereas the inferior portion is more active during hip extension. Knowledge of how the gluteus maximus is recruited may have an impact on exercise selection for performance and rehabilitation. The current study compared electromyographical (EMG) activation of the superior and inferior portions of the gluteus maximus muscle in 11 common therapeutic exercises using fine-wire electrodes.
