ObjectivesThis study evaluated the relationship between the skeletal muscle mass (SMM), obtained by predictive equations, and the body composition, nutritional aspects, functionality and physical performance in elderly people.MethodsThe sample consisted of adults aged 65 years or over from the cross-sectional study of the Brazilian Elderly Frailty Study Network, in Cuiabá, Mato Grosso State, Brazil. The anthropometric parameters, instrumental activities of daily living (IADL), Short Physical Performance Battery (SPPB), and handgrip strength (HGS) were evaluated. The SMM was estimated by 2 predictive anthropometric equations.ResultsBoth SMM equations correlated with age, anthropometric indices, SPPB, IADL, and HGS. However, only HGS and neck circumference strongly correlated in both equations, being higher in SMM II.ConclusionsIt seems that both equations are sensitive to obtain the SMM, contributing to the diagnosis of sarcopenia, nutritional status, and a physical performance condition.

Both protocols improved CVD and metabolic risk factors. The CWT presented favorable changes regarding lipid profile and flexibility; JOGG on glucose, waist/hip ratio and blood pressure. These results suggest that resisted exercise combined with aerobics should be considered for obese people. Nevertheless, regarding some basal differences between the groups , it was not possible to conclude that changes were due to exercise type or intra-group variability.
