- Primary Outcome Measures
Name Time Method <p>The primary endpoint will be muscle protein synthesis. Muscle protein synthesis<br /><br>will be calculated by differences in plasma and muscle tracer enrichments.<br /><br>Phenylalanine and tyrosine enrichment in plasma samples and in the muscle free<br /><br>amino acid pool will be measured using gas chromatography-mass spectrometry,<br /><br>while the phenylalanine enrichment in muscle proteins will be measured with<br /><br>GC-combustion IRMS. We measure muscle protein synthesis after nocturnal protein<br /><br>ingestion by nasogastric tube. </p><br>
- Secondary Outcome Measures
