Rationale: Age-related diseases and consequent decreased physical activity are main contributors to lean body mass (LBM) loss associated to aging. We hypothesize that total body potassium (TBK), an index of metabolically active LBM, would be decreased in healthy, physically active, elderly volunteers over a 3-year period. Method: LBM was measured by DEXA (Hologic QDR-4500) and TBK by whole body counter at time 0 (T0) and 3 years later (T3). Physical activity (PA) was evaluated by means of a validated frequency questionnaire (1). Statistical analysis between T0 and T3 data were done by means of paired t-test. Res…
