Purpose of this study is to determine the relationship between body mass index (BMI), body weight (BW) and height variables and staticdynamic balance of athletes specialized in different branches. Totally 160 active athletes (21,34 +/- 2,58 years), 78 female (21,10 +/- 1,63 years), 82 male (21,56 +/- 3,23 years) who did not have any health problems participated in the study voluntarily. Biodex Balance System was used for balance measurement. Static equilibrium measurements were performed on a fixed platform and dynamic equilibrium measurements were performed on 2 different levels (levels 1 and 6). Normal distribution indicators of the data were analyzed by Kolmogorov-Smirnov test, Q-Q Plots and histogramgraphs and it was found that the data did not comply with the normal distribution. Spearman-Rho test was used for statistical analysis of the data. While there was a positive correlation between BMI, BW and height and dynamic balance values (Level 1 and 6) of the participants (p<0,01), a significant negative correlation was found between BMI and BW. (p<0.05). According to the acquiredresults, it can be said that individuals with higher BW and BMI values can achieve postural balance better but have more difficulty in compensating when they lose balance. It is suggested that individuals with long stature should do more balance trainings in order to be successful especially in branches that include dynamic movements.
