Abstract
Amaç: Bu çalışmada PPAR-? geni intron 7 G/C ve PPARGC1A geni Gly482Ser polimorfizmlerinin, elit düzeydeki dayanıklılık sporcularının aerobik performansına etkisiniincelemeyi amaçladık. Materyal ve Metot: 60 elit dayanıklılık sporcusu ve 110 sedanter gönüllü kontrol üzerinde çalışıldı. Sporcu ve sedanter kontrol gruplarının aerobik performansı maksimum oksijen tüketim kapasitesi (VO2max) ile belirlendi. Periferik kandan GeneJet Genomik DNA Pürifikasyon kiti kullanılarak sporcu ve sedanterlerin DNA?ları elde edildi. PPAR-? intron 7 G/C ve PPARGC1A Gly482Ser polimorfizmleri PCR-RFLP yöntemleri uygulanarak genotiplendi. Sonuçlar Ki-kare analizi ve korelasyon yapılarak değerlendirildi. Bulgular: Sporcuların yaş ortalaması 21,38±2,83 (18-29) yıl ve sedanterlerin yaş ortalaması 25,92±4,88 (18-35) yıldı. Sporcuların VO2max ortalaması 42,14±7,6 ml/kg/dk iken, sedanterlerin VO2max ortalaması 34,33±5,43 ml/kg/dk bulundu. PPAR-? intron 7 G/C ve PPARGC1A Gly482Ser genotipleri sporcu ve sedanter grubunda karşılaştırıldığında genotip dağılımları (p=0,006, p<0,001) ve alel sıklıkları (p<0,001, p<0,001) bakımından istatistiksel olarak anlamlı bir fark saptandı. Ayrıca grupların aerobik performans değerlendirmesi sonucunda test parametreleri olan hız, süre ve VO2max değerleri bakımından sporcu ve kontrol gruplarının PPAR-? ve PPARGC1A genotip dağılımları arasında istatistiksel olarak anlamlı farklılıklar saptandı (p<0,001). Sonuç: Türkiye?de ilk kez yapılan bu çalışma neticesinde PPAR-? intron 7 G/C ve PPARGC1A Gly482Ser gen polimorfizmlerinin sporcularda aerobik performansı önemli derecede etkilediği saptanmıştır. Anahtar Kelimeler: aerobik performans; dayanıklılık sporcusu; peroksizom; polimorfizm
Aim: The purpose of this study was to investigate the effect of PPAR-? intron 7 G/C and PPARGC1A gene Gly482Ser polymorphisms on elite level endurance athletes aerobic performance. Material and Method: This study was carried out on 170 inviduals (60 elite level endurance athletes and 110 sedentary controls). Aerobic performance of athletes and sedentary control groups are defined by maximal oxygen uptake capacity. DNA was extracted from peripheral blood using GeneJet Genomic DNA Purification kit. Genotyping of the PPAR-? intron 7 G/C and PPARGC1A Gly482Ser polymorphisms was performed using PCR-RFLP methods, and satistical evaluations were carried out using SPSS 15.0. Results: Mean age of athletes were 21.38±2.83 (18-29) and control mean age were 25.92±4.88 (18-35). Mean maximal oxygen consumption of athletes were 42.14±7.6 ml/kg/min and controls were 34.33±5.43 ml/kg/min. We found significant differences between the athlete and control groups with respect to both PPAR-? and PPARGC1A genotype distributions (p=0.006, p<0.001, respectively) and allele frequencies (p<0.001, p<0.001, respectively). Additionally, when we examined PPAR-? and PPARGC1A genotype distributions according to the aerobic performance test parameters, we observed a statistically significant assoc ation between velocity, time and maximal oxygen consumption and PPAR-? and PPARGC1A genotypes (p<0.001). Conclusion: This is the first study in Turkey examined PPAR-? intron 7 G/C and PPARGC1A Gly482Ser gene polymorphisms in elite level endurance athletes. Our results suggest that PPAR-? and PPARGC1A genes have strong effect on aerobic performance of elit level athletes. Keywords: aerobic performance; endurance athletes; peroxisome; polymorphism
