NCT ID:
NCT00175968
Brief Summary:
Aim of the study is to assess the impact of the factors ´bed rest´ and ´hypocaloric nutrition´ on endothelium-dependent vasoreactivity in healthy volunteers.
Detailed Description:
In a randomized, four-phase cross-over study the effect of simulated microgravity (13 days of bed rest), energetic restriction (-25%, fat reduced), and their combination on endothelium-dependent and -independent vasodilation will be compared with ambulatory control conditions. Using venous occlusion plethysmography cumulative intraarterial dose-response curves to endothelium-dependent (acetylcholine) and -independent (sodium nitroprusside) vasodilators will be constructed in 10 healthy male volunteers before and on day 13 of each of the four intervention periods.
