The Effect of Hurdling Performance on The Adaptive Profile of Cerebral Blood Flow in Vestibular Irritation

The reactions of the whole organism that occur under the action of accelerations of rectilinear and rotational motion are factors that have a systemic effect on the cerebral blood flow. The use of hurdling performance in the structure of human physical activity can have a significant impact on the tone of the brain vessels, their elasticity and venous outflow in the development of fatigue caused by statokinetic stimuli.

The research purpose is to investigate the adaptive profile of cerebral blood flow in the implementation of statokinetic reactions in individuals engaged in hurdling performance.

108 university students took part in the study on a voluntary basis. All students were randomly divided into two groups. The adaptive profile of the cerebral blood flow was evaluated using rheoencephalography under the conditions of stabilometric testing at the beginning of the school year, after three and six months.

It is shown that a more perfect adaptation of the cerebral blood flow to vestibular irritation when barrier running exercises are included in the structure of physical activity is due to adequate stimulation of ampullary receptors caused by head tilts and contralateral synchronization of the muscles of the upper and lower extremities, which determine the kinematic structure of movements to overcome the barrier bar in conditions of rectilinear and nonlinear accelerations.

Our study revealed the process of developing stable compensatory reactions of cerebral blood flow in students during systematic hurdling performance.
