The article analyses the effects of classified jet lags on the lower-limb hemorheological and venous hemodynamic rates in the athletes specializing in speed-strength and cyclic sport disciplines, the athletes classified into those free of vascular pathologies and the diagnosed with functional or chronic disorders of venous blood circulation in lower limbs. Tests of the hemorheological and bio-impedance rates in the athletes specializing in speed-strength and cyclic sport disciplines and diagnosed with venous blood circulation versus the healthy ones found no statistically meaningful differences in the rates. Negative variation of the lower-limb hemorheological and bio-impedance rates were found to directly correlate with the flight time and have no correlation with the degree of venous circulation deficiency in the lower limbs. The flights up to 4 hours long were found to cause no meaningful health impairments as verified by the study data albeit the athletes diagnosed with functional or chronic lower-limb venous blood circulation disorders showed more expressed negative variations of the study rates. The flights above 4 hours were found to cause no meaningful health impairments as verified by the study data; albeit the detected variations were more expressed in the athletes diagnosed with functional or chronic lower-limb venous blood circulation disorders.
The study findings urge a set of reasonable therapeutic and preventive actions be taken to counter de-compensations of venous blood circulation in lower limbs.

Keywords: venous circulation deficiency in lower limbs, flight, elite athletes.
