Continuous data were recorded and filtered (Butterworth filter; cut-off = 10Hz) for the thoracohumeral (HRt) and glenohumeral axial rotation (HRs).
Relationship between thoracohumeral angle and glenohumeral angle and scapular variables were also analyzed by means of bivariate correlations.
The thoracohumeral angles (humerus angle with respect to thorax, HRt) at the extreme range-of-motion of shoulder ER were significantly smaller in the athletes group.
Concerning the extreme range-of-motion of shoulder IR, the athletes group showed a significantly greater range-of-motion thoracohumeral angle, and positioned the dominant scapula more in retraction and anterior tilt.
In our study, and concerning ER ROM, athletes showed less thoracohumeral (range-of-motion) than non-overhead athletes.
There was positive correlation seen in the athletes group between the thoracohumeral angles and scapular spinal tilt rotation at the extreme position of shoulder external rotation.
In the athletes group the thoracohumeral IR ROM was higher (~18[degrees]).
