NASA BED REST PROJECT CAMPAIGN 3

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 背景：美国宇航局的科学家们正在努力寻找方法，使宇航员在太空中度过长时间时保持健康和安全。 低头卧床休息是一个很好的方式来假装一个人在没有重力的太空旅行。 具体目的和程序：本研究中的受试者将在加尔维斯顿医院的特殊研究单位生活114天。 他们将在床上呆90天。 沿着卧床休息，这些研究将进行精神和身体测试，称为综合测试方案（ITR）和其他5名科学家的研究。 这些测试测量在卧床休息之前，期间和之后身体和精神的变化。 现在，许多这些测试都用于宇航员在太空飞行前后观察太空长途旅行的变化。 实验设计（总结）：为了在研究过程中尽可能多地了解情况，美国宇航局的科学家们将进行他们多年来开发的一系列测试， 航天员 此外，还有五组其他测试，将帮助所有的科学家学习新的和更好的方法，以帮助保持宇航员的健康 意义（摘要）：美国宇航局的科学家希望获得有助于在未来太空飞行中保持宇航员健康的信息。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Background: NASA scientists are working to find ways to keep astronauts healthier and safer when they spend a long time in space. Head down bed rest is a good way to pretend a person is traveling in space without gravity. Specific Aims and Procedures: Subjects in this study will live at the special research unit at the hospital in Galveston for 114-days. They will stay in bed for 90 of those days. Along with bed rest, these studies will have mental and physical tests called the Integrated Testing Regimen (ITR) and other studies of 5 scientists. These tests measure changes in the body and mind before, during and after bed rest. Right now, many of these tests are used on astronauts before and after space flight to watch the changes from long trips into space. Experimental Design (summary): In order to learn as much as possible during the study the scientists at NASA will do the set of tests that they have developed over many years for evaluating astronauts. In addition, there are five other sets of tests that will help all of the scientists learn new and better ways to help keep the astronauts healthy Significance (summary): NASA scientists hope to get information that will help keep astronauts healthy on future space flights.
