ÖZET
 Sporcularda bilişsel fonksiyon ve mental yorgunluk kavramı, spor performansında önemli bir rol oynamaktadır. Beyin fonksiyonunun beslenme ve diyet faktörlerinden etkilendiği düşünüldüğünde, beslenme uygulamalarının mental yorgunlukla başa çıkmada, sporcular için önemli bir çözüm olabileceği düşünülmektedir. Bu derlemede, sporcularda bilişsel performansı ve mental yorgunluğa karşı direnci geliştirmek için uygulanan beslenme stratejilerinin bilimsel kanıtları gözden geçirilmiştir. Karbonhidrat ve kafein, bilişsel fonksiyon ve mental yorgunlukta sporcular için en fazla sayıda raporun yayımlandığı besin ögeleri/bileşenleridir. Bulgular, bozulmuş bilişsel işlev durumları ve mental yorgunluk için karbonhidrat ve kafein alımının performansa olumlu etkileri olduğunu göstermiştir. Ancak güvenilir ve tutarlı faydaları ortaya koymak için gereken karbonhidrat ve kafein alımının optimal dozunu ve zamanlamasını belirlemek gerekmektedir. Omega-3 takviyesi ile hidrasyon durumunun mental yorgunluğu önlemede faydalı olabileceğine dair kanıtlar mevcuttur. dallı zincirli amino asitler [branched-chain amino acid (BCAA)], tirozin ve kreatin ile ilgili olarak bazı potansiyel fayda mekanizmalarına rağmen bulguların çelişkili olduğu görülmektedir. BCAA ve tirozinin, özellikle sporcularla yapılan çalışmalarda son yıllarda çok sınırlı olduğu da göze çarpmıştır. Polifenollerin sporcuların bilişsel fonksiyon ve mental yorgunluğuna etkisine yönelik sonuçlar değişkenlik göstermesine karşın, bilişsel performansta açık ve orta derecede bir iyileşme ile ilişkili olduğu belirlenmiştir. Sonuç olarak bilişsel fonksiyonun gelişimi ve mental yorgunluğu önlemede kanıtları güçlendirmek için farklı sporcu gruplarıyla bilişsel ve fizyolojik ölçümleri birleştiren tutarlı ve güvenilir sonuçlara dayalı bilimsel çalışmaların yapılmasına ihtiyaç vardır.

ABSTRACT
 The concept of cognitive function and mental fatigue in athletes play an important role in sports performance. Considering that brain function is affected by nutrition and dietary factors, it is thought that nutritional practices can be an important solution for athletes to overcome mental fatigue. In this review, scientific evidence of nutritional strategies applied to improve cognitive performance and resistance to mental fatigue in athletes was examined. Carbohydrates and caffeine are the nutrients/components with the largest number of reports published for athletes in mental fatigue. The findings revealed that carbohydrate and caffeine intake for impaired cognitive function and mental fatigue have positive effects on performance. However, it is necessary to determine the optimal dose and timing of carbohydrate and caffeine intake for reliable and consistent benefits. There is evidence that omega-3 supplementation and hydration status may be beneficial in preventing mental fatigue. Despite some potential mechanisms of benefit with regard to branched-chain amino acid (BCAA), tyrosine, and creatine, the findings appear to be inconsistent. Also, it has been observed that BCAA and tyrosine are very limited in recent years, especially in studies with athletes. Although the effects of polyphenols on cognitive function and mental fatigue of athletes vary, it was determined that they were associated with a clear and moderate improvement in cognitive performance. Consequently; there is a need for scientific studies based on consistent and reliable results combining cognitive and physiological measurements with different groups of athletes to strengthen the evidence in improving cognitive function and preventing mental fatigue.
