Methodologically and Psychological Aspects in the Gymnastics Training

The author has created two gymnastic exercises on parallel bars on the basis of objective logical analysis. One of them (bent with side straddleturn and twist on 90 degrees to longitudinal angle swing) is performed by the author and some other gymnastics. The next one—the same with open legs is performed only by the author (1989), which makes the article innovative activity. By this moment no other gymnast has performed the exercise.The significance of the physical and the technical as well as the psychological preparation for successful learning of new and difficult gymnastic exercises is underlined
