Objective:
Evaluate the scapular movement of Crossfit® practitioners and identify whether they present an increased incidence of scapular dyskinesis (SD) compared to non-practitioners.
Method:
A transversal study was evaluated quantitatively and dynamically, using retro-reflective spherical markers, the scapular movements of ten volunteers composing the control group, and 11 Crossfit® practitioners. The control group's results were used as a normality parameter and compared to those of the Crossfit® practitioner's group.
Results:
It was identified that the superior scapular rotation in the ascending phase is inferior in the group of Crossfit® practitioners (p = 0.02).
Conclusion:
The regular practice of Crossfit® causes scapular dyskinesis (SD), with alteration in the scapular superior rotation movement. .
