Gluteus Medius Muscle Activities during Standing Hip Abduction Exercises in the Transverse Plane at Different Angles.

Objective: To examine gluteus medius (GMed) muscle activity while performing standing hip abduction exercise in the transverse plane at different angles.

Material And Method: Muscle activity of both sides of the GMed was measured by electromyography (EMG) with a sampling frequency of 1,500 Hz. Participants were asked to perform standing hip abduction exercise in the transverse plane at different angles including 0 degrees, 15 degrees, 30 degrees, 45 degrees, 60 degrees, 75 degrees, and 90 degr Percent maximum voluntary isometric contraction (MVIC) of average EMG of GMed muscles was reportedfrom three trials for each limb.
