A Relationship between Static and Dynamic Postural Stability Index and Anthropometrics Index in Healthy Men and Women with Normal BMI Index

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. 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 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). 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.
