Abstract:
The aim of the research is to determine in which part of the brain the cerebral blood flow is concentrated during shooting and rest in biathletes. Method: The study was planned as two sessions. In the first session, body composition measurements were made in the laboratory, and in the second session, standing shot measurements were made with wheeled skis using real bullets on the Kandilli international biathlon track. The brain hemodynamics of the athletes were determined by examining the prefrontal region of the head with the fNIRS device during shooting and resting. Athletes were subjected to 5 repeated protocols with 30 sec rest sessions after each shot. A total of 25 shots were fired, including 5 shots within 30 seconds in each shooting period. Findings: As a result of the obtained data, oxyhemoglobin values obtained from channel 3 (p=0.021) located in the central part of the dorsolateral profontal cortex, channel 4 (p=0.020) located in the left part and channel 15 (p=0.024) located in the left part of the orbitofrontal cortex were found to be moderately significant. It was found that the oxyhemoglobin value obtained from channel 7 (p=0.013) located in the left part of the ventrolateral profrontal cortex was significant at a high level. No significant difference was found in the oxyhemoglobin values obtained from other channels. Result: It was found that the oxyhemoglobin values in the channels located in the middle and left dorsolateral, left orbitofrontal and left ventrolateral parts of the profrontal cortex were higher in the athletes participating in the study compared to resting during shooting. It can be said that this condition occurs as a result of the combined activation of physiological and mental processes during shooting.
