Shoulder/Neck and Bodybuilding

Hi Yarok

Interesting........I'd be keen to see if anyone else agrees with you or if you are alone with this theory. I can't quite see how a pec muscle which is overstretched can pull a humeral head forward?? I do however agree that the "rear part" is stiff but it isn't usually the muscular component causing the stiffness but the intervertebral and costovertebral joints causing the stiffness so some mobilisation here would help. The original question was about complaints of shoulder instability which is why I mentioned strengthening the scapular stabilisers.....of coarse this has to be done in conjunction with rotator cuff at a later stage but I believe working on the scapula initially to provide a stable base and then bringing in the dynamic stabilisers of the rotator cuff later is a better approach. I'd be interested to hear more about your theory.

I just thought I'd make another comment as I'm wondering if there may be some confusion here over anterior shoudler instability which is atraumatic and dynamic instability. I was under the impression we were talking about dynamic instability caused by muscle imbalances brought on by body building and overtraining some muscle groups vs others. On reflection, Yarok's comments about overstretched anterior structures would fit with an overstretched anterior capsule leading to instability in which case posterior structures often are stiff. This may be where some confusion has crept in. My understanding though is that atruamatic anterior instability is more common in athletes who are engaged in repetitive activities involving extremes of range of movement which overstress the capsule such as tennis, throwing as in baseball pitching etc.
