Abstract : In connection with the accumulations of physiol ogical information concerning the effects of cosmic flight on the human organism is felt the need of examining the tactics of experimental in vestigations. There are two possible ways of experimenting: (1) studying the relatively small number of standard physiological characteristics by imitating the effect of certain factors in condition of real cosmic flight; (2) investiga ting the physiological mechanism of the effect on the organism of the very same factors. The ne cessity and importance of experimentally inves tigating the physiological mechanisms are shown on examples from the field of lateral accelera tions. Results of investigating the hemodynamics of the small blood circulation circle, oxygen re quirement of heart muscles, O2 intensities in brain tissues and functions of the central nervous system in combination with literature data allow to formulate a chart of basic physiol ogical effects of lateral accelerations. Real appears to be the description (quantitative) of physiological displacements and construction of a model, reflecting the basic changes in the state of the organism at various situations of cosmic flight. The creation of such a model will allow to make a more basic evaluation and prog nosis of the state of the cosmonaut, to reduce the number of experiments of ''empirical'' type, and also to find effective means, increasing the resistance of the organism to various condinoons of flight.
