Aim of the study was the measure of the modifications of total MM sex, age, and BMI-related; body composition was valued with DEXA in 717 healthy and autonomous subjects. It was estimated the district lean mass (MM) of superior limbs (As), inferior limbs (Ai) and of truncus (Tr), and calculated percentual distribution of the MM between Ai and Tr. Aging acts on body composition as a factor unbalancing force ratios between limbs and troncus, penalizing muscular representativeness of inferior limbs and favoring, on the contrary, an axial cargo progressively more onerous. That offers a possible bio-mechanical interpretation of motor frailty of aging
