Before and after water immersion (for 3 days) tolerance of human volunteers to head-pelvis overload was evaluated on a centrifuge with a radius of 7.25 m. Neuro-muscular system functioning was studied by the H(Hoffman)-reflex and electromyography. The research conducted did not permit sufficient evaluation of the pathomechanism of secondary inhibition of the H-reflex. A simultaneous decrease in the amplitude of the pulse of vessels of the lobe of the floor of the auricle suggested a change in the level of supraspinal effects, caused by the state of cerebral blood flow.
