  Purpose

Dietary intervention to prevent sarcopenia in elderly people. The objective of this study is to test whether combined nutrient intake plays an important role in stimulation of the muscle protein growth in elderly people; and whether it represent effective strategies to overcome the impaired muscle protein synthesis in elderly when compared with young subjects.

Primary Outcome Measures:
  • Muscle protein synthesis [ Time Frame: 6 h postprandial period ] [ Designated as safety issue: No ]
    Muscle protein synthesis will be expressed as fractional synthetic rate (FSR) by dividing the increment in enrichment in the product, i.e. protein-bound C13phe, by the enrichment of the precursor (=plasma availability).
