RESUMO
The article deals with the development and correction of acute jet lag in a flight across several time zones. The investigation had the purpose to study dynamics of subjective and objective psychophysiological parameters and demonstrate methods of prophylaxis and correction of acute jet lag due to transmerdian flights. Subjects were 8 normal volunteers (experimental group) at the age of 26-55 years flying eastward over 7 times zones. The investigation included 3 stages: baseline, preparatory (21-d course of Euricoma longifolia extraction) and main (intake of donormil, cirkadin and artificial sleep during the flight). Functional diagnostics was performed on the baseline stage, on completion of the preparatory stage and on the next day after the flight (21-22 days from the beginning of the preparatory stage). Objective and subjective methods were used to evaluate the autonomic and cardiovascular systems and mental performance. In the control group (n = 4) functional diagnostics was performed on the same days. The investigations showed the benefit of preparation for transmeridian air travel and experimentally demonstrated positive effects of the proposed pharmacological correction of acute transmeridian jet lag.
