Objective: to study the dynamics of the alpha rhythm after local alpha stimulating training, as well as its preservation for twelve months by persons engaged in physical culture and sports.
Materials and Methods: the study involved 46 students engaged in physical culture and sports, sports qualifications of II level to the master of sports. The study group consisted of 25 young men who were local alpha stimulating training. The control group consisted of 21 people. Evaluation of the functional state of the athlete is to record EEG background with the two hemispheres with bipolar leads in 5 minutes with your eyes open, and then 5 minutes with your eyes closed (electrodes placed according to the international system «10-20» in the frontal and parietal regions). The survey was conducted throughout the year in certain time intervals.
Results: it was found that the safety indicators «background» electroencephalogram after passing local alpha stimulating training (LAST) depends on the initial power-rhythm students. The young men with low «initial» power-rhythm changes in the power of the alpha rhythm during the course, immediately after the LAST return to the «original» value. The young men with high «source» power of the alpha rhythm was identified set aside the effect is to increase the power of the alpha rhythm during the six months after the course LAST preserving posttreningovogo values one year after the course LAST.
Conclusions: irrespective of the value and the «original» power-rhythm for the students is characterized by increasing the power of the alpha rhythm after the passage of local alpha stimulating training. Timeframe safety indicators «background» electroencephalogram after local alpha stimulating training depend on the «original» level value of the alpha rhythm.
