The effect of amino acid administration on skeletal muscle blood flow

A protein meal increases renal and splanchnic blood flow and this study was undertaken to assess the effect of amino acids on skeletal muscle blood flow. In one group of ten subjects oral water was compared with oral amino acids and in a second group intravenous saline was compared with intravenous amino acids. Oral water produced no change in muscle blood flow while oral amino acids produced a significant increase. Neither intravenous saline nor intravenous amino acids had any significant effect.
