RELATIONSHIP BETWEEN BODY MASS INDEX AND POSTURAL DYNAMIC BALANCE AMONG 35-45 AGED WOMEN ABSTRACTThe aim of this study was to evaluate the relationship between body mass index (BMI) and postural dynamic balance among 35-45 aged women (n=40). It was measured BMI using Tanita BC-418 and stability indices were obtained using Biodex Stability System (eyes open and eyes closed). Subjects were tested 60 seconds, starting level 8 and finished level 3. It was found that 20% of subjects were normal (n=8), 45% were overweight (n=18), 35% were obese (n=14). There were found that statistically significantly difference between groups (normally, overweight and obese) in the open-eyed balance test (F(2,37)= 7.845, p<0.05) and there was a significant positive correlation between BMI and open-eyed balance ability (r=0.533, n=40, p<0.001). There weren't found statistically difference between groups in the closed-eyed balance test (p>0.05). In conclusion, it can be state that a decrease in balance stability is strongly correlated to an increase in body weight among 35-45 aged healthy women. This suggests that women should be healthy weight before menopausal stage and keep it because of body weight may be an important risk factor for falling.
