Gluteus maximus EMG amplitude is higher when muscle fibers are shorter (in full hip extension compared to flexion, in hip abduction compared to neutral, in hip external rotation compared to neutral, and in
posterior pelvic tilt compared to anterior pelvic tilt).
In this apparatus, gluteus maximus EMG amplitude was significantly higher in
posterior pelvic tilt compared anterior pelvic tilt (41 % of MVIC vs. 18 % of MVC).
There was a trend towards higher rectus abdominis muscle activity in the long lever plank with
posterior pelvic tilt compared to the long lever plank without posterior pelvic tilt (109 % vs. 90 % of MVIC).
There was a trend towards greater external oblique muscle activity in the long lever plank with
posterior pelvic tilt compared to the long lever plank without posterior pelvic tilt (148 vs. 111 % of MVC).

Comparing plank exercises, Schoenfeld et al. (2014) assessed the plank, the long lever plank (greater shoulder flexion), the plank with
posterior pelvic tilt, and the long lever plank with
posterior pelvic tilt.
The long lever plank variations resulted in higher rectus abdominis muscle activity
compared to the standard plank variations, irrespective of
posterior pelvic tilt.
Comparing the curl up and the
posterior pelvic tilt exercise, Sarti et al. (1996) measured rectus abdominis muscle activity.
Comparing isolation exercises, Schoenfeld et al. (2014) assessed variations of the plank exercise including the traditional plank, long lever plank (greater flexion of the shoulder), traditional plank with
posterior pelvic tilt, and long lever plank with
posterior pelvic tilt.
