Özet:
Giriş: Triatletlerin zorlandığı yarış bölümlerden olan bisiklet-koşu geçişinde gözlenen denge kayıplarını önlemek yarış başarısı için önemlidir.Amaç: Genç ve elit triatletlerde yorgunluk oluşturmayacak düzeyde yapılan submaksimal bisiklet egzersizinin denge üzerine etkisini değerlendirmekGereç ve Yöntem: Çalışmaya İzmir ilinde yaşayan 7 elit ve 8 genç triatlet katılmıştır. Sporculara VO2max ve anaerobik eşik testleri yapılmış ve buna göre belirlenen submaksimal düzeyde bisiklet egzersizi sonrasında Balance Master cihazıyla statik ve dinamik denge ölçümleri yapılmıştır.Bulgular: Elit sporcuların VO2max değerleri gençlerden anlamlı olarak yüksek bulunmuştur. ?Tek ayak üzerinde duruş? testi sol alt ekstremitede gözler açıkken yapıldığında gençlerde bisiklet egzersizi sonrasında gövde salınımının istatistiksel anlamlı olarak arttığı saptanmıştır (p<0,05). ?Tek ayak üzerinde duruş? testi sağ alt ekstremitede yapıldığında gençler ve elitler arasında; egzersiz öncesi ve sonrası değerlerde her iki grupta da anlamlı fark bulunmamıştır. Gençlerde sağ ve sol ekstremitelerle atılan öne adımın yerle temas zamanı istatistiksel anlamlı olarak azalmıştır (p<0,05). Elit sporcularda dinamik dengede istatistiksel olarak anlamlı bir farklılık saptanmamıştır. Bisiklet egzersizi sonrasında gençlerin sağ ve sol ekstremiteleriyle uygulamış olduğu kuvvet elitlerden anlamlı olarak az bulunmuştur (p<0,05).Sonuç: Bu çalışmadan elde edilen veriler yorgunluk oluşmaksızın görülen denge-koordinasyon kaybının var olan denge problemleri veya fiziksel özelliklerden kaynaklanabileceğini göstermektedir.Anahtar Kelimeler: elit triatlet, genç triatlet, denge, bisiklet-koşu geçişi, VO2max, anaerobik eşikABSTRACTAssesment of Balance in Junior and Elite Triathletes after Cycling ExerciseAslı BeğenIntroduction: Preventing balance problems in the cycle to run transition that is one of the hardest part of the triathlon race is important for race achievment .Purpose: The purpose of this study is to assest the effect of submaximal cycling exercise on balance in junior and elite triathletes.Material and Method: 8 junior and 7 elite triathletes who live in Izmir participated in this study.

When the unilateral stance test was performed for the right side, there is no significant values between junior and elite triathletes. In juniors, contact time values was decreased for right and left extremities after the cycling exercise significantly (p<0,05). There is no significant values for the forward lunge test in elite triathletes.
