Specifics of urgent adaptation of cardiovascular system in athletes at latitudinal displacement
The researchers applied the biorhythmological approach to estimate the effect of standard time shifts on the state of adaptive capabilities of the body of male athletes, residing and training in the conditions of the Khanty-Mansi Autonomous District, after the flight through several time zones. Physiological parameters were measured in 33 athletes of 16-18 years of age, specializing in sprint kinds of athletics. All of them were the members of the KhMAR-Yura team and had I-II sports categories. All of them flew from Surgut to the area of Kislovodsk at the same time as part of the general preparatory phase of the training camp and stayed there for 21 days. The authors suggest that hemodynamic and possibly regulatory (which are defined as a change of the key parameter of the LF order, showing the activity of the sympathetic centers of the oblongata) adjustments take place at strenuous physical loads, which are inevitable in a training camp.
