Background and Study Aim: The ability to maintain postural stability under the variable conditions of randori and during judo tournaments is one of the most important determinants of a judoka´s performance. The aim of this study was to answer the question whether under the maximal anaerobic performance followed there are changes of postural stability (PS) among elite junior and senior male judo athletes. If so, whether the differences concern both visual control and then limb preference and the type of the test used.

Material and Methods : Nineteen judo athletes (9 junior, 10 senior category) were tested. The multi-sensorial platform was used for posturographic examination. Anaerobic variables were detected using the Wingate test with a Monark 824E mechanical ergometer.

Results: Senior judo athletes achieved significantly better values of PS in comparison to juniors (F_(1,34) = 11.24, p = 0.00, η² = 0.25). In the one leg stance test, both groups produced significantly higher values than in the bipedal test (F_(1,72) = 159.81, p = 0.000, η² = 0.69). In the monitored groups, we found a significant effect of the physical load in the bipedal test (F_(1,34) = 19.56, p = 0.00, η² = 0.37), as well as in the one limb test (F_(1,34) = 49.03, p = 0.00, η² = 0.59). Changes in PS after exercise are manifested more in the non-preferred limb than in the preferred one.

Conclusions: The effect of maximal anaerobic exercise applied in our study was reflected in both senior and junior participants. Adult athletes appeared to have significantly better postural stability in comparison to juniors
