Substantial shifts in the relative alignment of the body parts will ultimately effect efficiency and where load is absorbed.
A common habitual posture is one in which the hip and pelvis is translated forward relative to the line between the ankle and the shoulder (see picture below) often a standing posture know and described as “sway posture”.
The line of gravity now falls behind the hip joint, resulting in a forward that increases load at the front of the hip. The muscles, tendons and ligaments at the front of the hip and/or pelvis will be exposed to greater stretching loads, while the lower back is relatively more compressed. In order to resist gravity now, higher muscle activity around the front of the thighs and hips and at the back of the lower legs, in the calves, is usually needed.
This posture is then not so efficient and enough time spent in such postures may over time contribute to fatigue, overload and ultimately pain at the front of the hip and/or in the lower back.
