Subject: RE: Low back pain and swimming As a swimmer with a "bad back", my discomfort during & after the swim is significantly reduced by focusing on pelvic tilt, even when swimming. It seems natural that your body's bouyancy should suffice to keep your spine in line, but I find that unless I focus on bringing my pelvis up towards my belly button and engaging my abs, I endup with a hyperlordosis (swayback ), which irritates my low back and my sciatic nerve. Your body rotation should come not just from your "hips", but your entire abdominal core from your ribcage to your pelvis (my own opinion, based on what I know of anatomy ). Find an anatomy book and look at the attachments of the core muscles from your ribcage to your pelvis, including abdominus rectus, and the two layers of obliques. Maybe that visual will help.
Second tip: Ala Total Immersion, focus on "pressing your buoy". By pushing your buoyant chest down into the water, your hips will pop up, also decreasing the lower back curvature.
In order for one set of muscles to contract, the opposing set has to relax. If you engage your abs and push your chest down, your lower back muscles MUST relax. On many swims, these are the only two focuses that I concentrate on in order to eliminate back pain. Edited by AdventureBear 2005-08-07 2:51 PM
