The Effects of Growth Hormone (GH) on Lipid Depots

Summary

This study aims at investigating the effect of growth hormone on lipid-content of muscle and liver as well as visceral fat mass in relation to insulin sensitivity. In addition, hormonal regulation and free fatty availability is assessed during a physical exercise at 50-60% VO2max. Finally, the value of physical exercise in diagnosing growth hormone deficiency is investigated. Hypothesis: 1) Lipid content of muscle and liver change with physical exercise and exercise capacity and free fatty availability will influence these changes. 2)Growth hormone replacement therapy will predominantly reduce visceral fat mass and increase free fatty availability. 3)Free fatty availability during exercise will be reduced in growth hormone deficient patients 4)Physical exercise may be an alternative way to diagnose growth hormone deficiency
