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. The purpose of this study is to test how a force created by spinning the space craft could be used to replace gravity during long space flights. For this study, the "artificial gravity" will be created by spinning subjects on a human centrifuge and space flight will be simulated by prolonged bed rest. Bed rest with the head tilted down slightly below the feet is a good way for researchers to imitate the changes that occur in a person's body while traveling in space without gravity. In this study, subjects will be confined to 21 days of 24 hours a day bed rest, with the head tilted down slightly to experience some of the changes an astronaut's body goes through during 21 days of weightless space flight. During those 21 days subjects will not get out of bed; however, once a day they will be wheeled on a gurney to the centrifuge facility. There, treatment subjects will spend 1 hr spinning on the centrifuge and control subjects will spend 1 hr on the centrifuge without spinning. Scientists will measure the functioning of many of the body systems before, during, and after bed rest to learn how an astronaut's body will change in weightlessness during space flight in the future, and how artificial gravity might be used to protect astronauts from some of the changes their bodies go through.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目及 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 这项研究的目的是测试如何利用航天器旋转产生的力来代替长途太空飞行中的重力。在这项研究中，将通过在人体离心机上旋转受试者来产生“人造重力”，并通过长时间卧床休息来模拟太空飞行。卧床休息，头部略低于脚部，是研究人员模仿人在无重力太空旅行时身体发生变化的好方法。在这项研究中，受试者将被限制每天24小时卧床休息21天，头部稍微向下倾斜，以体验宇航员身体在21天失重太空飞行期间所经历的一些变化。在这 21 天里，受试者不能起床；然而，每天一次，他们将被放在轮床上送到离心机设施。在那里，治疗受试者将在离心机上旋转 1 小时，而对照受试者将在离心机上旋转 1 小时而不旋转。科学家将在卧床休息之前、期间和之后测量许多身体系统的功能，以了解未来太空飞行期间失重状态下宇航员的身体将如何变化，以及如何利用人工重力来保护宇航员免受身体所经历的一些变化的影响。
