title: [Fundamental and applied objectives of investigations in immersion].
abstract: The results of extended comparative investigations into the hypogravity effects on the human motor system in space flight and ground-based experiments evidenced that dry immersions (DI) is the most adequate model of microgravity as time of development, degree and depth of structural and functional motor disorders in DI are very close to what is observed in real microgravity. High intensity and speed of the hypogravity effects during immersion as compared with bed rest hypokinesia the only difference from which is the level of support removal provided insight into the leading (trigger) role of support removal in genesis of the microgravity-induced syndromes of muscular deconditioning and hypogravitational ataxia. Involvement and paths of support afferentation within the muscular system were experimentally studied and verified. Much less understood are processes changing the system mechanisms. These issues as well as some nontrivial approaches to elimination of the negative effects of hypogravity were the subject of the multisided immersion experiment the results of which are presented in this book of the journal.
