Is there a link between physical inactivity and long term musculoskeletal complaints?  A recent large-scale prospective population-based study was designed to investigate the association between self-reported physical exercise at baseline and the prevalence of chronic musculoskeletal complaints.

The results of this study indicate that, physical exercise was associated with lower prevalence of chronic musculoskeletal complaints.   The study is clear to state that the results are not absolutely conclusive, and the results may be an indication of the chronic musculoskeletal complaints limiting the ability to perform physical activity.  Not necessarily the lack of physical activity causing musculoskeletal complaints.

I will go out on a limb and say that in my experience, the more physically active patients are;  the less likely they are to have chronic musculoskeletal problems.  And the ones that do have problems seem to respond better to treatment.
