Forty individuals were subjected to functional tests of body stability using the Biodex Balance System, and the resulting indices were correlated with bodymass, height, and bodymass index, and also compared between genders. Body mass was the main anthropometric factor that in�uenced variations in postural balance, with a high correlation between groups and with all variables. A linear regression analysis showed that body mass associated with BMI explained 66% of the overall stability, and body mass explained 59 % of the anteroposterior stability index and 65 % of the mediolateral stability index. In the female group, body mass explained 72 % of the overall balance, 66 % of the anteroposterior, and 76 % of the medio-lateral stability index. Increased body mass requires greater movements to maintain postural balance. Height and BMI presente
