Whole-body and splanchnic protein metabolism were determined in six young (mean age: 22.7 y) and six old (68.2 y) men before and during a standardized meal (41.8 kJ/kg) containing 15.6% protein, by using a combination of intravenous ([13C]leucine) and oral ([2H3]leucine) tracers. In the postabsorptive state, leucine flux and oxidation were similar in both groups when corrected for lean body mass (mean +/- SEM: 1.80 +/- 0.09 compared with 1.79 +/- 0.07 mumol.kg-1.min-1 and 0.55 +/- 0.02 compared… CONTINUE READING
