Head down tilt (-6 degrees HDT) examinations are commonly used simulation models for various microgravity induced changes in body functions. Body fluid distribution (by means of dye dilution and two independent multifrequency impedance techniques), water- and sodium-handling, and the plasma/serum concentrations of fluid balance related hormones have been determined in a randomized, controlled, cross-over study in 8 healthy test subjects. The comparison of responses to HDT and an upright control position with respective experiences from space shows some similarities but also various discrepancies between the terrestrial simulation and real microgravity.
头低位倾斜（-6度HDT）检查是用于模拟各种微重力引起的身体功能变化的常用模型。在一项针对8名健康受试者的随机、对照、交叉研究中，测定了体液分布（通过染料稀释和两种独立的多频阻抗技术）、水和钠的处理以及与体液平衡相关激素的血浆/血清浓度。将HDT和直立对照位置的反应与太空飞行的相应经验进行比较，结果显示地面模拟与实际微重力之间既有一些相似之处，也存在各种差异。
