Abstract
Load body mass in people with normal weight leads to an increase in posture sways and a decrease in balance. In this research, the aim is to compare the effects of load body mass on the stability of normal-weight men with obese men Under three bases of support and two vision conditions. For this purpose, 15 normal-weight and 15 obese male teachers and volunteers were selected, and the body mass of the normal-weight group was increased by weight loading until the average body mass index of the obese group was reached. The results of the analysis of variance for repeated data showed that the difference in the mean volume of posture sways between the normal weight group and the obese group after load body mass was significant (P<0.05). Also, the mean volume of posture sways of the normal weight group before and after load mass was not significant (P<0.05). Therefore, it can be concluded that men with normal weight do not suffer significant balance fluctuation due to load mass and under conditions of lack of access to vision and reduced base of support. Therefore, load mass does not affect the fast dynamics of static stability. Also, compared to the obese group, the normal weight group has a higher level of balance, which indicates that load mass does not affect the slow dynamics of static posture stability.
