Introduction: The high prevalence of osteoporosis in women (one in three) has caused concern in several health areas, which have sought to understand mechanisms for preventing this phenomenon, especially in childhood and adolescence. In this sense, gymnastics and ballet appear as a protective alternative, however there are still gaps in the literature about the effect of both on the bone health of girls, mainly because the articles do not involve relevant bone parameters such as geometry and do not compare both modalities. Objetive: Compare bone density and geometry between artistic gymnastics and ballet practitioners. Methods: Cross-sectional study conducted in the city of Presidente Prudente. Sample composed of 36 young females, classified as: Control (n=12), Artistic Gymnastics (n=12), Ballet (n=12). Bone mineral density was estimated using Dual-energy X-Ray absorptiometry in i) right femoral neck, ii) lumbar spine, and bone geometry was calculated using the encore software 2011 V13.60, Lunar iDXA, training variables were collected through a face-to-face questionnaire. Statistical analyzes were performed using the BioEstat program considering a significance level of p<0.05. Results: The weekly training volume of the gymnastics group is 41% greater than that of the ballet group, when correlating the areal bone mineral density and the weekly training volume, we observed that the gymnastics group presented a significant and moderate correlation only for the strength index (p= 0.023), and although the mean time of practice does not differ between the modalities, this variable seems to positively affect the results of aBMD of the femur and lumbar spine of gymnasts, as well as the modular section of ballerinas and the CSMI of gymnasts. Conclusion: It is believed that the weekly training volume and the practice engagement time have a positive influence on the gain in areal bone mineral density. Hypothesis: It is expected to find a higher aBMD in the femur region of gymnasts when compared to the other groups, as well as a hip geometry. (AU)
