Sarcopenia and obesity have been independently associated with physical function decline, however little information is currently available on the relationship between sarcopenic performance, mainly in middle aged women. The present study aims to estimate prevalence of explore performance middle-aged women from Northeast Brazil. A cross-sectional (40–65 years) living Parnamirim, a city Brazil (n = 491). Physical was assessed by grip strength, knee extensor flexor strength (isometric dynamometry), gait speed, chair stands. Using bioelectrical impedance analysis (BIA), appendicular skeletal muscle mass divided height squared (kg / m2) used define sarcopenia. Waist circumference ≥ 88 cm defined as abdominal obesity. Sarcopenic coexistence outcomes were regressed four groups combinations sarcopenia obesity, adjusting for potential confounders (age, education menopausal status). Prevalence rates obesity-sarcopenia were: (7.1 %), (67.4 (12.4 %) normal (13 %). Women had significantly lower weaker extension flexion longer time raise compared non-obese non-sarcopenic (p.values < 0.001). Except stands, these statistically significant differences also found obese There no difference speed across (p 0.50). 7 % this population it poor performance. may occur limitations beyond pure sarcopenia-related or alone.
