Comparação do equilíbrio postural de adultos jovens em função do sexo

Abstract

Different morphological characteristics of individuals affect performance in different physical abilities. Added to this, it is know that men and women do not have the same distribuitions of body tissues. Therefore, the physical capacity postural balance may be altered depending on the sex of the individual. Thus, this study aims to conduct a comparison of static postural balance between male and female young adults. Have participated in this study 29 active indivuduals (12 females and 17 males) aged between 18 and 28 years of age. For evaluation of postural balance used a force platform AMTI (Advanced Mechanical Technologies, Inc.), which measures where the three components of ground reaction force (vertical, mediolateral and anteroposterior) and also measures the moments around the axis (anteroposterior and mediolateral). For data analysis we used descriptive statistics. Normality of data distribuition was verified using the Shapiro-Wilk. Comparison between groups was performed using the Mann-Whitney U and Student t test. The statistical software used was SPSS 11.5 for windows. The level of significance for all tests was 5%. The results showed statistically significant differences in all variables, except as an eye open for the variable amplitude of center of pressure in the mediolateral direction. Thus, one can conclude that the postural balance of females had lower values of oscillation than the rates for males, and womens postural balance postural balance better than men.
