Abstract
The aim of this study was to investigate the effect of electrical activity and information processing in the cerebral cortex on the electrical power of the brain between martial artists and inactive individuals.
Methodology: This causal study was performed on 20 female athletes aged 15-25 years (10 in the experimental group, 10 in the control group), the experimental group in terms of age and sex, height and weight, and some anthropometric features such as Body mass index was matched. From the subjects, first the CWT test was performed to evaluate the information processing in the brain. Then, electrical activity of the cerebral cortex was recorded using Brain mapping and EEG. It should be noted that subjects in both groups were relieved of daily pressures and brains by listening to brainwave refresher music for 15 minutes before the electrical activity of their cerebral cortex was recorded and their brain information processing was assessed.
Results: According to the information obtained, the results of independent t-test showed that strength exercise significantly reduced the P300 wave latency and the number of errors in the CWT test. It has also significantly increased the amplitude of the P300 wave (P≥0.05). Also, the results of the study for changes in the absolute power of brain waves in the whole brain and in different brain lobes showed that there is a significant difference between the two groups of athletes and inactive people. And the absolute power of brain waves in the whole brain and in the brain lobes of athletes was higher than inactive people. The relative changes of brain waves in the whole brain and in different brain lobes were significant and these changes showed a relative increase in brain waves in the brains of athletes. And the changes in latency and amplitude of P300 wave as well as CWT test factors (information component in brain processing) between the two groups were significant and these changes were in favor of the athlete group.
Conclusion: It can be concluded that chronic strength training improves the information processing process in the cortex of karatekas at rest.
