Neurophysiological mechanisms determining accuracy and stability of purposeful movements in archery

The achievement of the maximum result in archery is determined not only by a high accuracy, but also by its stability. The central organization mechanisms of purposeful movements of a high accuracy by electroencephalogram indicators have been studied in particular works. However, the stability of highly-accurate shots is not clarified until now. The purpose of this study was the determination of Физиология №4 l 2018 87 a structural and functional organization in archery depending on the accuracy and stability of its implementation. Four archery athletes at the age of 16-19of Master of Sports qualification took part in the study. Electroencephalogram (EEG) at rest, in preparation for the shot and its execution has been recorded by the electroencephalograph. The individual averaged topographic maps of power of EEG spectrum in the standing state with open eyes and in the aiming phase before the highly-accurate shot have been calculated. The significance of differences has been determined by the single-factor analysis of the variance...
