Abstract Of Research The research aims to identify changes in the wave of electrical activity of the brain using a device (EEG) wave (alpha and beta) as an indicator for the selection and training of players fighting actual contest " kumite " the sport of karate, the researcher used the descriptive method using a screening method due to its relevance to the nature of the research, was selected sample purposively players Karate allocate an actual fight (kumite) Oriental Sports Club, Eastern district Karate, who achieved ahead of Republic Championship Karate center allocates an actual fight (kumite) in different weights for the sports season 2015, 2016, and who have not achieved an advanced position, so for (9) players, and the sample was exploratory number of (1) single-player, and reached basic sample number (8) players, The most important results are no statistically significant differences between the two players who have achieved an advanced position, and the players who have achieved ahead of Republic Championship Karate center differences allocate an actual fight (kumite) in a wave of electrical activity of the brain using a device (EEG) wave (alpha - beta) on both sides of the brain (the side right, left side) in favor of the players who have achieved an advanced position, electrical activity of the brain on the side (right side, left side) is considered a factor in the speed performance and pay punches and kicks and achievement and sporting excellence, is also considered a strong indicator for the selection and training of players fighting actual contest "kumite" the sport of karate. Key words: The electrical activity of the brain (EEG) - The Actual Fighting "Kumite".
