Resistance exercise augments the acute anabolic effects of intradialytic oral nutritional supplementation

Abstract

There were no differences in metabolic hormones, plasma amino acid and whole-body protein balance between the interventions. During the post-HD phase, PO + EX retained a positive total amino acid (TAA) balance (primarily due to essential amino acid) while PO returned to a negative TAA balance although this difference did not reach statistical significance (78 +/- 109 versus -128 +/- 72 nmol/100 ml/min, respectively; P = 0.69). In the post-HD phase, PO + EX had significantly higher net muscle protein balance when compared to PO (19 +/- 16 versus -24 +/- 10 microg/100 ml/min, respectively; P = 0.036) We conclude that a single bout of resistance exercise augments the protein anabolic effects of oral intradialytic nutritional supplementation when examining skeletal muscle protein turnover.
