OPTIMIZING THE PERFORMANCES OF SWIMMERS CHILDRENS, IN SWIMMING, BY EDUCATION OF COUPLING, COMBINING AND REGULATION OF THE SPECIFIC STROKES

The ability to combine and couple the movements makes possible the coordination of different motor structures. It confers the global movement fluency, removing the possible interferences, which can arise between the partial actions the complex activity is made up of. The rhythmicity is a fundamental physiological phenomenon, expression of some specific characteristics of the nerve cell. Due to it, even the arrhythmic movements can become rhythmic actions. Based on this characteristic a gradual concentration of the stimulus in the active muscles is produced, which ensures the saving of effort.
