Detection of Minor Changes in Fluid Volume or Tonicity in Healthy Volunteers.

Detection of Minor Changes in Fluid Volume or Tonicity in Healthy Volunteers.

This study is aimed at detecting minor changes in hydration volume and tonicity. We will use healthy students of both sexes who will ingest fluids and nutrition that should lead to specific changes in both intracellular and extracellular volumes. The protocol is based on laboratory exercises previously carried out at The Arctic University of Norway (UiT).
