SUMMARY
Background: Understanding the brain function and how it coordinate the motor activity, means to have a map of brain using a lot of modern technologies which can give us information about the role and functions of different brain areas. Objective: The aim of our study is to explore the brain activity using electroencephalography (EEG) and make the evaluation of differences in brain functions depend on specific sport activity. Methods: We make the study on two lots of athletes from judo (12subjects) and volleyball (11subjects), yrs. 22. All of them have a great sport activity experience and the anthropometric characteristics are similar. For recording the brain activity we use Nihon EEG product. The protocol of the research includes recording of brain activity during muscle contraction and relax of hand flexors. The parameters that we follow up are alpha1, alpha2 and theta waves. The information have been analysed using statistic methods and Pearson coefficient. Judo players present a little bit increase values of theta waves and we observe also a correlation between alpha waves for dominant hemisphere. For the second lot the values of theta waves are highest. Conclusions: Analyse the behaviour of EEG waves could help the trainer and staff for approach the training results in term of build the brain and motor pattern. This is the result of professional approach of training based on neurophysiologic assessment using the brain mapping.
