Then in correcting a slump, we’re likely to thrust our ribs up, and tighten the lower back. Our abdominals aren’t doing their work, and this can lead to lower back pain. Over time, slumping can greatly affect the lungs (Jenkins et al. 1988, Lin et al. 2006) and other organs.
Maintaining good length in the front of the body can help restore the role of a critical abdominal muscle – the transverse abdominus which is an important stabiliser of the back and pelvis ( Hodges & Richardson 1996). More upright sitting postures also involve more recruitment of pelvic floor muscles in resting activity (Sapsford et al. 1997).
What posture are we looking for when sitting?
Here are some experiments and thought bubbles for you to try.
Now place a hand on top of your head, and now lighten your hand, and think about your head floating up towards the ceiling, slightly in front of you.
You can also do all of this while lying on the floor.
Experiment – lengthening upwards from our base
Thought bubble - Think about lengthening up from here to your forehead, but don’t allow your ribs to project forward as you do it.
Now take your hand up about a handspan, and find the point where the lower ribs meet (in the centre of the model’s black top).
Thought bubble - Now ask for length up from the pubic bone to where the lower ribs meet, and from there up to the forehead. Allow your head to float up towards the ceiling, slightly in front of you.
