Hip
extension angular velocity is
affected by gender, being higher in males than in females (Harbili, 2012), and some reports indicate that
knee extension angular velocity may also be
affected by gender, being higher in males than in females (Gourgoulis et al. 2002), although this has not been confirmed by all studies (Harbili, 2012).
Similarly, Fujisawa et al. (2014) found that hip flexion angle did not
affect gluteus medius muscle activity when the
knee was in full
extension during isometric hip abduction.
