“…A number of MVIC positions have been used in the literature to assess the gluteus maximus, including the Biering-Sorenson position ( Cambridge et al, 2012 ; McGill, McDermott & Fenwick, 2009 ), the prone straight leg hip extension position ( Barton et al, 2014 ; Worrell et al, 2001 ), the prone bent leg position ( Jakobsen et al, 2013 ; Youdas et al, 2013 ), the prone straight leg position with 70° of hip flexion ( Simenz et al, 2012 ), and the standing bent leg position ( Boudreau et al, 2009 ). The most commonly used position, however, is the prone bent-leg (90°) hip extension with manual resistance applied to the distal thigh (PRONE) ( Choi et al, 2015 ; Emami, Arab & Ghamkhar, 2014 ; Hislop et al, 2014 ; Kang et al, 2013 ; Kendall , 2005 ; Oh et al, 2007 ).…”
