Effect of whey protein supplementation combined with resistance training on body composition, muscular strength, functional capacity, and plasma-metabolism biomarkers in older women with sarcopenic obesity: A randomized, double-blind, placebo-controlled trial

Summary Backgrounds & aims Obesity and sarcopenia are independent illnesses associated with contemporary dietary and physical activity behaviors, aggravated by aging. Their coexistence is termed sarcopenic obesity (SO). Hence, increasing protein intake and resistance training (RT) are interventions that could counteract these illnesses. The objective of this investigation was to analyze the effects of whey protein (WP) supplementation associated with RT on body composition, muscular strength, functional capacity, and plasma-metabolism biomarkers in older women with SO. Methods Twenty six sarcopenic (appendicular lean soft tissue ALST  Results The WP group presented greater ( P P P Conclusion Whey protein combined with RT increased ALST, and decreased total and trunk fat mass, improving sarcopenia and decreasing SO in older women, with a limited impact on inflammation.
