The purpose of this study was to compare the effects resistance training (RT) on body composition, muscle strength, and functional capacity in elderly women with without sarcopenic obesity (SO).A total 49 (aged ≥60 years) were divided two groups: SO (non-SO, n=41) (n=8). Both groups performed a periodized RT program consisting weekly sessions for 16 weeks. All measures assessed at baseline postintervention, including anthropometry composition (dual-energy X-ray absorptiometry), strength (one repetition maximum) chest press 45° leg press, (stand up, elbow flexion, timed "up go").After intervention, only non-SO group presented significant reductions percentage fat (-2.2%; P=0.006), waist circumference (-2.7%; P=0.01), waist-to-hip ratio (-2.3; P=0.02), neck (-1.8%; P=0.03) as compared baseline. Muscle biceps curl increased (12.9% 11.3%, respectively), while (50.3%) (40.5%) Performance chair stand up go" improved (21.4% -8.4%, whereas flexion performance (23.8%) (21.4%). Effect sizes motor tests higher magnitude group, general, considered "moderate" "trivial" group.Results suggest that adaptations induced by weeks are attenuated woman SO, compromising improvements adiposity indices gains capacity.
