Students who learn through methods that are appropriate to their cerebral dominance style achieve high results, unlike students who learn in ways that are inconsistent with their prevailing cerebral pattern, This research aims to know the effect of an educational program using the ( right-left-balanced) brain dominance on improving the level of performance of the fourth Poomse for taekwondo students, The researcher used the experimental method, through the experimental design of the three groups, after the measurement (tribal-dimensional). The sample included the third year students, Taekwondo, of the Faculty of Physical Education for girls Zagazig University, and they are (46) students, and their ages range between (20-21) years, and they were divided into three group experiments for each type of brain domination (12 right - 12 left). - 12 balanced women, a total of (36) female students, and (10) female students for exploratory study, The most important results indicated that the educational program using brain dominance had a positive effect in improving the skill performance of the three cerebral patterns (right - left - balanced), and the presence of statistically significant differences in the dimensional measurements of the three cerebral patterns (right - left - balanced) in the level of skill performance of the Poomse Fourth (Taeqeuk Sa Jang) in favor of balanced brain sovereignty, and that a balanced pattern is the most appropriate cerebral patterns to learn and practice Poomse, The researcher recommended the need to take advantage of the results of this study and conduct more studies regarding the use of brain dominance over other sports activities, And the need for more scientific studies of brain sovereignty that address other skills in taekwondo, and use the measure of sovereignty when selecting taekwondo players and directing them to appropriate activity for them, whether fighting or Poomse.
