Abstract

  Symmetrical structure of human body allows to perform asymmetrical and symmetrical extremities movement. However, most people use mainly right hand, what could be an effect of social tradition and genetic background. Both factors probably causes a right - hand dominance in human motor. The problem what kind of movement, asymmetrical or symmetrical, is more profitable for man has not been solved yet. Since alternative attitudes to this problem not include many social, biological, physiological and psychological aspects of the human motor, a new concept has been developed to create the better movements of the upper extremities. In contrast to other theories the concept prefers interrelation between both asymmetrical and symmetrical elements in the human motor system. In practice, the interrelation is individually adjusted to the subject, according to his experience in movement. The concept is based, therefore, on a procedure of symmetrization of movements, that is on the equalizing process of efficiency for left and right hands with a preference for an individual dominance the one of it. Starosta (1975, 1984, 1990, 2008) and others authors showed that the symmetrization process improves the coordination of movement and its efficiency, quality and accuracy. It has also been showed that recovery of the exhausted hand can be accelerated, when the other hand performs some exercise. Recent cross- sectional study proved that 20% of judoist who were under symmetrization process during preparation for Olympic Games of 1980 won over 50% of medals, including 6 gold among 7 possible. I conclude, therefore, that the symmetrization process is beneficial for sport performance, working and everyday movements practice.
