Functional profile of assymetry in qualified athletes specializing in fencing

The profile of the lateral organization of a brain is recognized as one of the leading factors defining adaptation reserves of an organism, physical and intellectual working capacity. Interhemispheric asymmetry is one of fundamental regularities of a brain activity which is under the influence of sports training. The special attention is drawn by studying of the matter in relation to fencing where the influence of lateral preferences is obviously shown in technique and tactics of sports actions. The article shows the qualitative and quantitative analysis of specifics of the individual profile of asymmetry (IPA), and also its touch-sensitive and motor components in highly skilled athletes specializing in fencing. It was examined 15 qualified male athletes aged from 17 till 25 years old (the 1st grade, candidate of master of sports, master of sports) who are specializing in fencing, and 10 contemporaries with the right profile IPA ("pppp"), not playing sports. Touch- sensitive and motor asymmetries were tested in 43 tests. It was revealed that the right-handed athletes practicing fencing had increasing of activity of the left hemisphere of a brain that is naturally defined by specifics of a sport, its asymmetry and requirements imposed to the athlete when performing the techniques applied in a duel. The list of IPA options in fencers is considerably narrowed and specific to this sport. It was revealed a large number of "the hidden lefthanders", 2 athletes with the leading left hand.
