Objective: It is know that gluteus medius and minimus muscle measures change according to gender and body mass index (BMI). It may differ anatomically between right and left sides. Accordingly the study was planned to investigate the differences between the right and left ventrogluteal (VG) regions according to the active and passive use of the individuals. Material and Methods: The study was planned in a descriptive, observational and cross-sectional manner to examine the anatomical structure of the VG site, as right and left. The study was performed on 93 healthy persons between the age of 18 and 35 years, who agreed to participate in the study. In the collection of the research data, the form including the indicative characteristics and the ultrasonographic measurement data of the individuals were used. Results: It was found that the differences of the gluteus medius in the right and left sides were statistically significant (p<0.05), when compared by gender there was a significant difference only in women (p<0.05), and there was a significant difference (p=0.002; p=0.004) with regard to BMI. When the correlation of the values measured according to BMI are examined, it was found that there was a high level of relationship and significant difference to the highest degree between the right and left VG site measurements in a positive way, in normal, mildly obese and obese individuals. Conclusions: It has been observed that there can be differences on the right or left side of the VG site. These differences also vary according to gender and BMI.
