ABSTRACT
Background: Changing in anthropometrics index can cause a reduction in the balance of body and may be considered as a contributing factor in falling down. Therefore, this study aimed to evaluate the correlation between body mass index [BMI] and static and dynamic postural balance among healthy subjects.
Materials and Methods: Fifty healthy male and female University students were selected through simple non-probability sampling. Static and dynamic stability index were measured by means of Biodex Balance System and also a tape measure and non-digital scale were used to examine Anthropometrics index. Obtained data were analyzed through Independent t-test and Pearson Correlation test[p<0.05].
Results: Results did not show a significant correlation between static stability index and BMI among male and female groups [p>0.05] [for example: the overall static stability index r= 0.21, p=0.30 in male group] while, there was observed a significant correlation between dynamic stability index and BMI, Weight and Height variables among male and female groups [p<0.05] [for example: the overall dynamic stability index r= 0.54, p= 0.005 in male group]. Besides, there was an adverse significant correlation between the range of stability index and BMI [for example: the overall limit of dynamic stability r=-0.45, p=0.02 in male group].
Conclusion: present results indicated that there are a direct relationship between dynamic stability and anthropometrics indexes and also, an indirect relationship between the range of stability and anthropometrics indexes.
