Abstract Purpose The objective of this study was to assess whether artificial gravity attenuates any long-duration head-down 60 bed rest (HDBR)-induced alterations in motor unit (MU) properties. Methods Twenty-four healthy participants (16 men; 8 women; 26–54 years) underwent 60-day HDBR with (n = 16) or without (n = 8) 30 min artificial gravity daily induced by whole-body centrifugation. Compound muscle action potential (CMAP), MU number (MUNIX) and MU size (MUSIX) were estimated using the method of Motor Unit Number Index in the Abductor digiti minimi and tibialis anterior muscles 5 days before (BDC-5), and during day 4 (HDT4) and 59 (HDT59) of HDBR. Results The CMAP, MUNIX, and MUSIX at baseline did not change significantly in either muscle, irrespective of the intervention (p > 0.05). Across groups, there were no significant differences in any variable during HDBR, compared to BDC-5. Conclusion Sixty days of HDBR with or without artificial gravity does not induce alterations in motor unit number and size in the ADM or TA muscles in healthy individuals.

Human spaceflight is a multiteam effort requiring the coordination and collaboration not only of individuals within a team (mission control or space crew) but importantly also between teams. In this chapter, the strategies and procedures these expert teams have established to ensure common task and team models, and to facilitate their communication and joint performance, will be discussed. The chapter also includes a discussion of the component teams of the mission control/space crew multiteam system, highlighting important features of their (intra)teamwork. The teamwork challenges of future long-duration space exploration are discussed, as are ongoing efforts and research needs to address them.

The problem of creation and application of artificial gravity for people in space is considered as a short history of ideas, technologies, projects of the XIX-XXI centuries in the paradigm of space exploration and life outside the Earth. A general definition, the description of ways to create artificial gravity, its modes are given. A brief analysis of history, periodization, classification are made. Important examples of ideas, technologies, projects are proposed. The realities and prospects are described. The main conclusions and recommendations are formulated.

A manned space mission to Mars might take as long as 1 year each way. Consequently, artificial gravity is being considered as a way of preventing the debilitating effects of long-duration exposure to microgravity on the human hotly. The present article discusses some of the problems associated with adapting to the rotation levels that might be used to generate artificial gravity. It also describes how exposure to background-force levels greater or less than the 1-G force of Earth gravity affects orientation and movement control. The primary emphasis of the article is that human movement and orientation control are dynamically adapted to the 1-G force background of Earth and that accommodation to altered force levels or to rotating environments requires a wide range of adaptive changes.
