BİLİŞSEL YORGUNLUĞUN EGZERSİZ VE SPOR PERFORMANSINA ETKİLERİ

Cognitive fatigue (CF) is considered as one of the factors affecting performance in exercise and sports. The purpose of this review is to explain the concept of cognitive fatigue, how cognitive fatigue is formed, how it is evaluated, and to discuss the results of studies related to the subject and thus to make suggestions for future research. For this reason, the studies in the literature have been searched in different databases and listed as effects on; “a) endurance performance, b) anaerobic power, maximal strength and speed performance, and c) sport-specific skills, motor and cognitive performance”.  According to the results, it was observed that BY had a negative effect on exercise and sports performance. In general, it caused impairments in endurance, motor performance, and sport-specific skills and decision-making, but did not affect performance in maximal or supramaximal activities. The negative effects of CF on performance are thought to be due to the increase in perception of effort, neurotransmitter distribution in the brain, and decreased level of motivation. In future studies, neurophysiological changes during cognitive tasks that lead to CF can be examined in more detail, and could be focused on how to eliminate the effects of BD.
