Abstract :Objective: Obesity, currently one of the important health issues, can be defined through Fat Tissue Mass insert ignore into journalissuearticles values(FTM); and Lean Body Mass insert ignore into journalissuearticles values(LBM);. The study aimed to investigate to what extent do FTM and LBM are associated with movement strategies of Sit-to-Stand insert ignore into journalissuearticles values(STS); task in individuals with obesity. Methods: Forty-nine obese individuals insert ignore into journalissuearticles values(52,83 ± 7,39); with no diagnosis of any health condition included in the study. The Balance Master System was used to evaluate the STS movement. STS task was analyzed by means of Weight Transfer Time insert ignore into journalissuearticles values(WTT); insert ignore into journalissuearticles values(second);, Rising Index insert ignore into journalissuearticles values(RI); insert ignore into journalissuearticles values(force exerted by legs-%Body Weight);, the Center of Gravity insert ignore into journalissuearticles values(COG); sway velocity insert ignore into journalissuearticles values(degrees per second);. The FTM and LBM were regressed against each STS parameter including age as a covariate. Results: The regression models could explain 10-21% of the variabilities in STS parameters: RI insert ignore into journalissuearticles values(21%);, COG sway velocity insert ignore into journalissuearticles values(11%);, WTT insert ignore into journalissuearticles values(10%);. FTM significantly related to RI insert ignore into journalissuearticles values(β: – 0.287, p=0.040);, but not with COG sway velocity insert ignore into journalissuearticles values(β: 0.270, p=0.073); and WTT insert ignore into journalissuearticles values(β: – 0.038, p=0.802);. LBM was significantly associated with RI insert ignore into journalissuearticles values(β: 0.435, p=0.003);; yet, not with COG sway velocity insert ignore into journalissuearticles values(β: – 0.100, p=0.066);, WTT insert ignore into journalissuearticles values(β: – 0.092, p=0.549);. Conclusion: This study revealed that FTM and LBM can explain the significant percent of the variation in RI during STS task, meaning a decrease in FTM and an increase in LBM provided support to rise during STS task. Moreover, an increase in FTM deteriorated postural stability. Improving LBM and decreasing FTM would be an effective strategy to improve STS in the obese population to increase their agility and could encourage physical activity participation.
