NASA BED REST PROJECT CAMPAIGN 3

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。背景：NASA科学家正在努力寻找方法，让宇航员在长时间呆在太空时更健康、更安全。头朝下卧床休息是假装一个人在没有重力的情况下在太空旅行的好方法。具体目标和程序：这项研究的受试者将在加尔维斯顿医院的特殊研究单元生活114天。他们将在其中的90天里卧床休息。除了卧床休息，这些研究还将进行名为综合测试方案(ITR)的心理和身体测试，以及对5名科学家的其他研究。这些测试测量了睡前、卧床期间和卧床后身体和精神的变化。目前，这些测试中的许多都是在宇航员太空飞行之前和之后进行的，以观察长途太空旅行的变化。实验设计(总结)：为了在研究中尽可能多地了解情况，NASA的科学家们将进行他们多年来为评估宇航员而开发的一套测试。此外，还有另外五组测试将帮助所有科学家学习新的、更好的方法来帮助保持宇航员的健康意义(摘要)：NASA的科学家希望获得有助于在未来的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.
