Abstract

Summary: The aim of this study was to evaluate the postural control of obese young adults with normal body mass index during different static (bipedic and unipedic support) and dynamic postural conditions (gait velocity and limits of stability) in order to compare the static and dynamic balance of these individuals. A cross‐sectional quantitative study was carried out to evaluate static and dynamic balance in 25 sedentary individuals. The sample was divided into two groups, 10 in the normal‐weight group (24.70 ± 3.89 years and 21.5 ± 1.66 kg m −2 ) and 15 in the obese group (26.80 ± 5.16 years and 35.66 ± 4.29 kg m −2 ). Postural evaluation was performed through visual inspection, and balance analyses were performed using the Timed Up & Go test (TUGT) and Balance System (Biodex). Descriptive analyses, Fisher's exact test and Mann Whitney U ‐tests were performed using the Statistical Package for Social Sciences (SPSS – 20.0, Armonk, NY) software. Most of the obese volunteers presented postural alterations, such as head protrusion (47.6%), hyperkyphosis (46.7%) and hyperlordosis (26.7%). Medial–lateral dynamic displacement, risk of falls and mean time to perform the limits of stability test and TUGT were higher for obese subjects ( P < 0.05), while there were no significant differences between the groups ( P > 0.05) for static balance tests for either bipedal or unipedal tasks. The disadvantage presented by the young obese subjects occurs in dynamic activities, representing worse balance and an increase in time needed to accomplish these activities.
