AHSG and sarcopenia: In brief, elevated levels are associated with lean muscle mass (Ahsg), prevention of oxidation muscle decline and sarcopenia (Alb), improved glucose uptake and reduced fat accumulation (Apoa1 and 4), regulation of oxidative stress (Arg1), maintenance of calcium levels for muscle contraction (Casq1), adaptive thermogenesis (Nnat), and muscle contraction (Serpina1d).
