Influence of sex and resistance training status on orofacial muscle strength and morphology in healthy adults between the ages of 18 and 40: A cross-sectional study.

Results from our cross-sectional study would suggest that exercise-stimulation to the facial muscles during resistance training of the limbs and trunk did not reach a level where orofacial muscle strength could be changed. Sex differences in facial muscle thickness are very unique, although the reasons are unclear.
