NASA FLIGHT ANALOGS/BED REST RESEARCH PROJECT CAMPAIGN 5

该子项目是利用 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来源获得主要资金， 因此可以在其他CRISP条目中表示。列出的机构是 中心，不一定是研究者的机构。 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。 头朝下卧床休息是一个很好的方式来模仿一个人在太空旅行没有重力。 头朝下卧床休息有助于研究人员研究地球上的人，这种方式会导致身体在没有重力的太空旅行中经历的一些变化。在这项研究中，科学家们将测试使用一个温和的振动平台，以保持骨骼质量，肌肉力量和平衡，在头向下卧床休息。 为了在研究过程中尽可能多地了解情况，科学家们将测量骨骼、肌肉、心脏、循环和神经系统的变化，以及营养和免疫状态。在研究期间，受试者将在90天内保持头部向下倾斜的状态。 沿着卧床休息，他们将进行精神和身体测试，以测量他们在卧床休息前、期间和之后的身心变化。在本研究的卧床休息部分，受试者每天将接受10分钟的振动程序。 当他们躺在床上时，受试者将被固定在适当的位置，他们的脚靠在一个温和振动的板上，弹簧连接到受试者将穿的背心上。科学家们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. 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 mimic a person traveling in space without gravity. Head-down bed rest helps researchers study people on earth in a way that causes some of the changes the body goes through while traveling in space without gravity. In this study scientists will test the use of a mildly vibrating platform to preserve bone quality, muscle strength, and balance during head down bed rest. In order to learn as much as possible during the study, the scientists will measure changes in bone, muscle, heart, circulation, and nervous system, as well as nutrition and immune status. During the study subjects will stay in bed with their head tilted downward for 90 of those days. Along with bed rest, they will have mental and physical testing to measure changes in their body and mind before, during and after bed rest. Every day during the bed rest part of this study subjects will undergo a ten minute vibration procedure. While they are lying in bed the subjects will be held in place with their feet against a mildly vibrating plate by springs attached to a vest that the subject will wear. Scientists hope to get information that will help keep astronauts healthy on future space flights.
