Performing back squats with
greater stance width seems to involve greater gluteus maximus EMG amplitude (McCaw & Melrose, 1999; Paoli et al. 2009).
Greater stance width and faster bar speed were found to increase adductor longus muscle activity.
Not exact matches
In a nutshell, the anatomic traits that are associated with a more upright squatting posture include:
greater heel elevation,
greater ankle dorsiflexion mobility, shorter femur length, longer torso length, wider
stance width, more abduction, a higher bar position on the back,
greater quadriceps strength and increased intent to target the knee extensors.
Comparing the effect of squats with different
stance widths, Escamilla et al. (2001a) reported no differences in hip moment arm lengths between the narrow, medium, and wide
stance width squats at any point in the lowering and lifting phases, except at 45 degrees of knee flexion in the lifting phase, when the medium and wide
stance width squats displayed
greater hip moment arm lengths than narrow
stance width squats.
Comparing different
stance widths, both McCaw and Melrose (1999) and Paoli et al. (2009) found that muscle activity was
greater during squats with a wide
stance width compared to those with a narrower
stance width.
Although
stance width appears to have no effect,
greater hip external rotation angles (up to 30 degrees) appear to cause increased hip adductor muscle activity.
Comparing squats with different
stance widths, Escamilla et al. (2001b) found that muscle activity was
greater in narrow
stance width squats compared to wide
stance width squats.
A lower, wider front clip — enlarged to provide
greater engine cooling — adds visual volume to the lower half of the Sportage's face, resulting in a planted and aggressive
stance, though it keeps the same overall
width, 73.0 inches, as its predecessor.
