Classic ballet is a type of sport that requires specific body characteristics like a lean figure, with low fat percentage and body weight. Thus, assessing body composition demonstrates great importance for maintaining body fat at healthy levels and compatible with dance. This study aimed to evaluate the body composition of classical ballet practitioners through the Electric Bioimpedance (BIA), as well as to compare their results with athletes and sedentary. A cross-sectional study was conducted, with data collection between June 2016 and May 2018 in the city of Natal-RN. The sample consisted of 37 dancers. The body composition was evaluated by a tetramer BIA apparatus. Ten predictive equations of BIA were selected to evaluate the fat-free mass (MLF) between the groups and compare them to each other. The ANOVA test was used followed by the Tukey post-test to compare the MLG averages of the three groups studied and then compare the results between the different predictive equations of MLG. Most of the dancers presented BMI within the eutrophic range, as well as the other groups. When comparing the% MLG of the dancers with sportsmen and sedentary women, it was possible to observe that the dancers had a higher% MLG (72.87%) when compared to the sportsmen group (69.86%) and sedentary (60.38%). In relation to the predictive equations of BIA for MLG that showed similarity among themselves in the three groups evaluated were eq. 1 (RJL systems - manufacturer), eq. 3 (Segal et al., 1988), eq. 7 (Houtkooper et al., 1992) and eq. 9 (Sun et al., 2003). Therefore, it is observed the positive impact that the classic ballet provides the health of its practitioners, promoting greater MLG and lower MG. As for the results obtained by the predictive equations of BIA, it is not ruled out that a previous validation was done with a reference method in order to choose the best equation for this population.
