[Preventive effect of acute thermal exposure during hypokinesia]. / Profilakticheskoe znachenie ostrykh teplovykh vozdeistvii pri gipokinezii.

Rat experiments have shown that adaptation to acute thermal effects increases the functional ability of the heart and blood circulation. This results in an increased thermal tolerance and hypoxic resistance of the myocardium. The prophylactic effect of acute thermal exposures during hypokinesia is related to a significant reduction of the level of metabolic and functional changes in the heart and skeletal muscles during diminished motor activity.

[Change in blood circulation in the orthostatic posture during hyperthermia]. / Izmenenie krovoobrascheniia v ortostaticheskom polozhenii pri gipertermii organizma.

It has been shown that orthostatic tolerance does not deteriorate if the level of hyperthermia and weight losses are controlled. Orthostatic intolerance develops at a critical level of hyperthermia and water losses. The mechanisms of this effect are described. The results obtained can be used to improve the aerospace expertise quality.
