Abstract

G-loads tolerance following hypodynamia during extended flights and effectiveness of countermeasures against possible negative impacts were studied. Subjects performed 5-hr simulated flights after which they were centrifuged with a g-gradient of 0.1 u/s in the relaxed state, and with a g-gradient of 1.0 u/s at complex-profiled 2 to 9 units in anti-g suit VKK-15. Tested were three sets of countermeasures (A, B, C) combining the following methods: physical exercises, VKK-15 provided massage of the lower body, 30-s exposure to 5 g, use of the profiled stiff and cushioned seats, electrical stimulation of the back and waist, and an air-cushion. The countermeasures were applied every hour on flight. Hypodynamia during the five-hour fighter flight was shown to have a weak detrimental effect on the pilot's functional state, performance and g-tolerance which were tempered by the proposed combinations of countermeasures.
