Values are presented as mean ± standard deviation or number. %MVIC, %maximum voluntary isometric contraction; GMa, anterior subdivision of gluteus medius; GMm, middle subdivision of gluteus medius; GMp, posterior subdivision of gluteus medius; TFL, tensor fasciae latae; QL, quadratus lumborum; PD, pelvic drop exercise; PDE, pelvic drop exercise with an isometric hip extension of non-weight bearing leg; PDF, pelvic drop exercise with an isometric hip flexion of non-weight bearing leg; CI, confidence intervals.
