Which Exercises Target the Gluteal Muscles While Minimizing Activation of the Tensor Fascia Lata? – 2013
– Selkowitz et al
– To compare hip abductor muscle activity and to determine which exercises are best for activating the gluteus medius and the superior portion of the gluteus maximus, while minimizing activity of the tensor fascia lata (TFL).
– 20 healthy persons participated. Electromyographic signals were obtained from the gluteus medius, superior gluteus maximus, and TFL muscles using fine-wire electrodes as subjects performed 11 different exercises
