Assessment of the Brain Cortical Activity of Professional Cavers

The brain, as an influential organ in athletic performance, specializes in each sport according to the form of its activity. Depending on the type of exercise and the basic processing needs of the brain in that sport, the brain takes a specific form of activity. In the sport of caving, some characteristics such as orientation can play a key role in a person s success. The aim of this study was to investigate the working form of the cerebral cortex in professional caving athletes.Thirty-two male and female players underwent electroencephalography (EEG) at the professional level. EEG was measured in both closed and open eyes conditions. The player was sitting passively on a chair, and data were recorded for each player for at least ten minutes. The mean and standard deviation of the absolute and relative power of the cortex of nineteen brain regions in the beta band was calculated through descriptive statistical methods.In the closed eyes condition, the mean absolute power at frequencies of ۸ to ۲۵ Hz in the central and left peritoneal areas (P۳-Pz) of all subjects was reported higher than normal. Also, at these points, the standard deviation of absolute power at frequencies of ۸ to ۲۵ Hz in these subjects was higher than normal.According to the results, such a form of brain processing may be an advantage. Adaptation of these areas to the orientation areas in the brain raises the possibility that these changes are a new arrangement of brain activity to improve orientation, or that people with this type of processing are more successful in this area.
