ÖZET
 Amaç: Bu çalışma, potansiyel renal asit yükünün [potential renal acid load (PRAL)] taekwondo sporcularında diz ekstansör kaslarının izokinetik kuvveti ve anaerobik performansa etkisini incelemek amacıyla gerçekleştirildi. Gereç ve Yöntemler: Çalışmaya 27 erkek, 19 kadın olmak üzere toplam 46 taekwondo sporcusu dâhil edildi. Sporcuların beslenme durumu 7 günlük 'Besin Tüketim Kaydı Formu' doldurularak değerlendirildi. Vücut kompozisyonu, Biyoelektrik İmpedans Ölçümü ile diz ekstansör kaslarının kas kuvveti izokinetik dinamometre ile anaerobik performans Wingate testi ile değerlendirildi. Çalışmaya katılan sporcuların besin tüketim kaydı değerlendirilerek diyet PRAL değerleri hesaplandı ve sporcular diyet PRAL değeri negatif [PRAL (- )] olanlar (n=14) ve diyet PRAL değeri pozitif [PRAL (+)] olanlar (n=32) olarak ayrıldı. İstatistiksel analizlerde anlamlılık düzeyi p0,05); kadın sporcuların hayvansal protein alım düzeylerinin PRAL (+) grubunda daha fazla olduğu (p0,05). Kadın ve erkek sporcularda PRAL (+) ve (-) olan gruplarda diz ekstansör kaslarının izokinetik kas kuvvetinin benzer olduğu, grupların anaerobik performansları arasında fark olmadığı belirlendi (p>0,05). Sonuç: Çalışma sonucunda PRAL değeri negatif ya da pozitif olan kadın ve erkek sporcuların diz ekstansör kasının izokinetik kuvvetinin ve sporcuların anaerobik performansının benzer olduğu belirlendi.

Anahtar Kelimeler: Diyet asit yükü; izokinetik kas kuvveti; anaerobik performans
ABSTRACT
 Objective: This study was carried out to examine the effect of potential renal acid load (PRAL) on the isokinetic strength of knee extensor muscles and anaerobic performance in taekwondo athletes. Material and Methods: A total of 46 taekwondo athletes, 27 males and 19 females, were included in the study. Body composition was evaluated by bioelectrical impedance measurement, muscle strength with isokinetic dynamometer, anaerobic performance was evaluated by Wingate test. Food intake records of athletes were evaluated, their PRAL values were calculated and athletes were separated to groups: those with negative PRAL value [PRAL (-)] (n=14) and those with positive PRAL value [PRAL (+)] (n=32). The statistically significance value was accepted as p0.05); It was determined that animal protein intake levels of female athletes were higher in the PRAL (+) group (p0.05). In female and male athletes, in the PRAL (+) and (-) groups, the isokinetic muscle strength of the knee extensor muscles was similar, and there was no difference between the anaerobic performances of the groups (p>0.05). Conclusion: As a result of the study, it was determined that the isokinetic strength of the knee extensor muscle and the anaerobic performance of the athletes were similar for male and female athletes with a negative or positive PRAL value.

Keywords: Dietary acid load; isokinetic muscle strength; anaerobic performance
