FUTBOLCULARDA BCAA VE KREATİN ALIMININ VÜCUT KOMPOZİSYONU ÜZERİNE ETKİSİ

Öz

Bu çalışmada, futbolcularda dallı zincirli amino asitler (BCAA) ve kreatin (KR) suplementasyonunun vücut kompozisyonu üzerine etkisinin incelenmesi amaçlanmıştır. Bu çalışmaya, yaşları 18-26 arasında olan, antrenmanlı 24 gönüllü erkek futbolcu katılmıştır. Futbolcular deney; BCAA (n=8) – KR (n=8) ve plasebo; (PLA) (n=8) grupları olmak üzere rastgele üç gruba ayrılmıştır. Deney gruplarına araştırmacı gözetiminde günlük kullanım şekli ve dozajı uygun olarak 7 gün boyunca 5000 mg BCAA ve 2000 mg kreatin suplemantasyonu yapılmıştır. Araştırmada, plasebo grubuna ise verilen besin desteğine eşit miktarda ve şekilde buğday kepeği verilmiştir. Çalışma tek kör uygulama olarak yapılmıştır. Analizler ön test-son test yöntemi kullanılarak deneklerin günlük yaşantı, beslenme ve antrenman programları bozulmadan 7 gün ara ile eşit fiziki şartlarda yapılmıştır. Vücut ağırlığı ve iskelet kası ağırlığı verilerine bakıldığında üç grupta da istatistiksel olarak anlamlı farklılık bulunamamıştır (p>0,05). Vücut yağ kütlesi ve yüzdesi değerlerinde hiçbir grupta anlamlı farklılık yoktur (p>0,05). Toplam vücut suyu, beden kitle indeksi (BKİ) ve metabolizma hızı parametreleri incelendiğinde gruplarda istatistiksel anlamlılık tespit edilmemiştir (p>0,05). Protein ve mineral seviyelerinde istatistiksel fark mevcut değildir (p>0,05). Tüm verilerin gruplararası karşılaştırmalarına bakıldığında istatistiksel olarak anlamlı bir farklılık bulunamamıştır (p>0,05). Futbolcularda beslenme stratejilerine bağlı olarak besin takviyesi kullanımı incelenmiştir. Bu doğrultuda, BCAA ve kreatin tüketiminin; sporcu sağlığı ile birlikte üst düzey sportif performans gösterebilmenin olmazsa olmazlardan biri olan ideal bir vücut kompozisyonu üzerine etkisine rastlanılmamıştır. Her ne kadar bazı parametrelerde olumlu veya olumsuz değişimler tespit edilmiş olsada, bu sonuçlarda anlamlı farklılıklar ortaya çıkmamıştır.
