[LBNP training of crew members of the Saliut-6 orbital station].

This paper describes the protocols of LBNP training of five prime crews that flew onboard Salyut-6. It is indicated that LBNP is one of the major constituents of countermeasures that must be performed inflight. LBNP may help adapt to weightlessness-induced blood redistribution and predict the level of postflight orthostatic tolerance.
