Neural Mechanisms of Intuitive Tactical Decision-making Predominance of High-level Fencing Athletes

Intuitive decision-making is a typical form of thinking in sports situation. The purpose of the study was to explore the neural mechanisms of tactical intuition predominance of elite fencing athletes. This study selected 39 subjects, including elite fencing athletes (N=8), level-1 fencing athletes (N=14), level-2 fencing athletes (N=11) and non-level fencing athletes (N=6). Event-related potential (ERP) recording was collected to compare between different level of fencing athletes. According to the operational standards of sports intuition, the responses of elite, level-1 and level-2 fencing athletes belonged to intuitive decision-making and that of non-level fencing athletes belonged to random guessing. ERP data showed that the mean amplitude of P1 and peak amplitude of P3, positives slow wave (PSW) of elite fencing athletes were higher than those of general (level-1 and level-2) fencing athletes. The peak latency of PSW was shorter than that of general fencing athletes at relevant cerebral cortex regions during the process of intuitive tactical decision-making. The results indicated that the tactical decision-making strategy of elite fencing athletes mainly aimed at the accuracy. Their anticipating speed was faster than the other general sport activities (1500 ms). The pointing focus degree of exogenous attention and the updating degree of mental token of judging tactics intention were higher. The neural mechanisms of performance predominance maybe the nerve activity levels of P1, P3 and PSW evoked at the special cerebral cortex being higher and the evoked time of P3 and PSW being earlier.
