From the present study, it is concluded that the increase in the thickness of the supraspinatus tendon is directly related to the practice of volleyball since the highest values of tendon thickness were found in volleyball practitioners. Regarding the relationship between the measurements of the thickness of the supraspinatus tendon and gender, it was concluded that this presented higher values for the male gender.

Regarding the relationship between the measurements of the thickness of the supraspinatus tendon and age, it was concluded that the thickest tendons were found in individuals between the ages of 26 and 29 and the thinnest in those between the ages of 18 and 21, which allowed us to conclude that the thickness of the supraspinatus tendon increases with increasing age. This trend in age may lead to the conclusion that volleyball players also present an increase in the thickness of the supraspinatus tendon due to overstrain when compared to non-practitioners.

Ultrasound elastography enables qualitative as well as quantitative assessment of the tissue elastic properties, aiding in differentiation between the diseased and normal tissue. It seems that the older the practitioners, the thicker the tendon, and consequently the loss of elasticity. More studies are needed in different sports to better understand these relations.
