Post-exercise Protein Intake for Active Children

Today, there is an important lack of knowledge on the effects of dietary protein on protein metabolism after physical activity in children. Here, the investigators will measure changes in whole body protein metabolism using minimally invasive techniques and stable isotope methodology at rest and after physical activity with the intake of milk protein.

Primary outcomes

  1. Whole body protein balance

    Time frame: Participants will be followed for 10 days prior to assessment of whole body protein balance.

    Whole body protein balance will be measured by stable isotopes.

Secondary outcomes

  1. Whole body protein metabolism, metabolites

    Time frame: Participants will be followed for 10 days prior to assessment of whole body protein metabolism and metabolites

    Whole body protein metabolism by stable isotopes and metabolite concentrations in plasma and urine.
