The aging process is associated with a decline in physiological functions, including a reduction in muscle quality, as well as changes in cardiometabolic risk factors. Thus, the aim of this study was to verify if a correlation exists between muscle strength and quality and cardiometabolic risk markers in older women. Thirty older women (66.13+ or -5.26 years, 67.33+ or -12.45 kg, 1.54+ or -0.07 m, body mass index: 28.20+ or -4.72) were submitted to the evaluation of muscle thickness and strength and blood analysis of cardiometabolic risk markers (glucose, basal insulin, C-reactive protein, total cholesterol, HDL-cholesterol, LDL-cholesterol, VLDL-cholesterol, triglycerides, and HOMA-IR). No significant correlations were found between muscle phenotypes and markers of cardiometabolic risk, even after adjustment for confounding factors. The present study indicates that muscle strength or quality is not correlated with markers of cardiometabolic risk.Original Abstract: O processo de envelhecimento esta associado a um declinio nas funcoes fisiologicas, refletindo em reducoes na qualidade muscular, bem como em alteracoes de marcadores de risco cardiometabolico. Nesse sentido, o objetivo do estudo foi verificar a associacao entre qualidade muscular e marcadores de risco cardiometabolico em mulheres idosas. Trinta mulheres idosas (66,13+ or -5,26 anos, 67,33+ or -12,45 kg, 1,54+ or -0,07 m, 28,20+ or -4,72 IMC) foram submetidas a avaliacao da espessura e forca musculares do quadriceps, e a analise sanguinea de marcadores de risco cardiometabolico (glicemia, insulina basal, proteina C-reativa, colesterol total, HDL-colesterol, LDL-colesterol, VLDL-colesterol, triglicerideos, e indice HOMA-IR). Nao foram encontradas correlacoes significativas entre os fenotipos musculares e os marcadores de risco cardiometabolico estudados, mesmo com controle para fatores de confusao. A presente pesquisa indica nao haver correlacao entre forca e qualidade muscular com os marcadores de risco cardiometabolico estudados.
