Dietary Interventions for Muscle Mass

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
Maastricht University Medical Center
ClinicalTrials.gov Identifier:
NCT01145131
First received: June 15, 2010
Last updated: September 13, 2011
Last verified: September 2011
  Purpose
Dietary intervention to prevent sarcopenia in elderly people. The objective of this study is to test whether meat structure plays an important role in protein digestion, to maximise the amino acid availability and to stimulate the muscle protein growth in elderly people.

Condition Intervention
Aging Other: Intact or minced beef meat

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Open Label
Primary Purpose: Prevention
Official Title: Dietary Interventions for Muscle Mass

Further study details as provided by Maastricht University Medical Center:

Primary Outcome Measures:
  • Muscle protein synthesis [ Time Frame: 6 h postprandial period ]
    Muscle protein synthesis will be expressed as fractional synthetic rate (FSR) by dividing the increment in enrichment in the product, i.e. protein-bound D5phe tracer, by the enrichment of the precursor (=plasma availability).


Secondary Outcome Measures:
  • Dietary amino acid plasma availability [ Time Frame: 6h postprandial period ]
    The exogenous rate of phenylalanine appearance will be used to assess the bio-availability of dietary-protein derived amino acids in the circulation during the 6h postprandial period following meat intake


Enrollment: 12
