Fischer and Houtz (1968) also reported greater gluteus maximus EMG amplitude in full hip extension compared to greater degrees of hip flexion, during hip extension. (strengthandconditioningresearch.com)
Gluteus maximus EMG amplitude is greater in full hip extension compared to flexion (Worrell et al. 2001), in abduction compared to neutral (Kang et al. 2013; Suehiro et al. 2014), in external rotation compared to neutral (Sakamoto et al. 2009; Suehiro et al. 2014), and in posterior pelvic tilt compared to anterior pelvic tilt (Queiroz et al. 2010; Tateuchi et al. 2012; Tateuchi et al. 2013; Choi et al. 2014).
