Abstract

Hungarian University of Physical Education, Budapest, Hungary A gymnast's high-level performance consists of several factors. The neuromuscular and cardio-respiratory systems are burdened to extreme. Proprioreceptors, visual receptor and their reliable mobilization have an important role fro111 the beginning of the exercise to its end. Restoring and maintaining equilibrium in different elements of gymnastics have dominant significance in certain phases. Posturography interests coaches of gymnastics being a type of sports requiring high accuracy equilibrium. The aim of our present study is to examine equilibrium in model-situations: in traditional and sharpened Romberg position. The examination included the situation with closed feet, too. The circle of subjects in the experiment is the Hungarian national male team of gymnastics: 10 persons. (Age 18-24.) Measurements were carried out with a force platform hype Adam/, whose output signals were used to determine continuously the centre of mass ofthe subject. Excerpts of results After exercise, traditional Romberg test with closed feet: R-s: 11, 11, 9, - 9, 8 - 19, 10 - 9,8,7 nun. Sharpened Romberg test: R-s: 20, 14, 13 - 18, 19, 13 - 15, 10 - 18, 16 mm. 'Mean values: for R1 = 10,l nun and for R2 = 15,6 nun /Closed eyes/
