Abstract

Objective of the study was to profile the cerebral blood flow variations in counting tests after the rated static and dynamic physical loads. Subject to the study were athletes of cyclic and acyclic sport disciplines (n=40, qualified at least Candidates for Master of Sport) split up into 2 equal groups, namely Track and Field Group (TFG) and Weightlifting Group (WLG). Two Reference Groups (RG1 and RG2) were composed of 40 university students qualified with the basic health group. All the subjects were 18-23 years old. Rheoencephalographs (REG) of the subjects were recorded in the relatively quiescent state, and then the subjects were offered cognitive (computing) tests with new REG being recorded in the process. Thereafter the subjects warmed up and performed the proposed physical exercises under surveillance of an instructor. Immediately after the required static and dynamic loads, new REG were recorded in the relatively quiescent state and in the cognitive test process. The study demonstrated that the post-static-load cerebral haemodynamic variations were more expressed in the Weightlifting Group versus that in the Track and Field Group after the cyclic loads. Moreover, the physical loads were found to cause a stabilizing effect on the cerebral blood flow rates in cognitive process. The cyclic loads were found to create favourable conditions for the cerebral activity being more efficient.
