[Hemodynamic indicators in men during constantly increasing overloads].
The effect of acceleration on central hemodynamics was investigated in centrifugation experiments. Also examined was the protective effect of muscle tension, anti-G suit, and of an altered acceleration vector. It was demonstrated that visual disorders were caused by a decrease in cardiac output. The countermeasures diminished the rate with which cardiac output declined due to the higher values of stroke volume that were produced by the anti-G suit and a changed body position. Arbitrary muscle tension ensured the effect only as a result of increased heart rate.
