FUTBOLCULARDA SUPRAMAKSİMAL BACAK EGZERSİZİNDE FARKLI YÜKLERİN GÜÇ VE ZİRVE LAKTAT KONSANTRASYONUNA ETKİSİ.

Abstract

Bu çalışmanın amacı, genç futbolcu/arda farklı yüklerde yapılan supramaksimal bacak egzersizinin güç parametreleri ve zirve laktat (ZLA) konsantrasyonu metabolizması üzerine etkisini incelemektir. Çalışmaya 10 genç erkek futbolcu (yaş: 14,90 i 0,32 yıl, boy: 165, 5 i 8,55 cm, vücut ağırlığı: 52,40 i 9,37 kg, VOM": 49, 82 i 4,37 ml.kg".dk") gönüllü olarak katılmıştır. Deneklere iki gün arayla rastgele sıra ile üç kez farklı yüklerde (60 g.kgVA" (Y6.0), 67 g.kgVA" (Y6. 7) ve 74 g.kgVA" (Y7.4)) Wingate Testi (WanT) uygulanmıştır. Her test için zirve güç (Zgüç), ortalama güç (Ogüç) ve yorgunluk indeksi (Yİ) hesaplanmıştır. Dinlenik ve testler sonrasında 0. 1. ve 3. dk ve sonrasında her 3 dk'da bir LA ölçülmüştür. L6.0, L6.7 ve L7.4'de mutlak ve vücut ağırlığına oran/anmış Zgüç (sırasıyla; 514,24 i 125,47 W, 607,47 $ 186,89 W, 591,04 i 189,91 W;p>0, 05), Ogüç (sırasıyla, 372,57 :I: 89,88 W, 411,93 :I: 92,03 W, 396,97:ı: 91,22 W; p>0, 05) ve Yİ (sırasıyla, % 50,54 $ 12,43, % 50,53 $ 12,63, % 44,15 $ 22,50) değerleri benzer bulunmuştur (p>0,05). Egzersiz sonrası ZLa değerleri arasında anlamlı fark saptanmamıştır (sırasıyla; 10, 78 :l: 1,09 mmol.i’, 10,76 $ 1,97 mmol.i’, 10, 70 $ 0,89 mmol.i’,' p>0,05). Y6.0, Y6.7 ve Y7.4'de ZLA sürelen' arasında anlamlı fark saptanmamıştır (sırasıyla; 6,0 1- 1,5 dk, 4,66 $ 1,58 dk, 6,00 $ 2,13 dk; p>0, 05). Bu çalışmanın sonuçları, genç futbolcu/arda supramaksimal bacak egzersizlerinde güç parametrelerinin ve kas La metabolizmasının uygulanan yüke bağlı olmadığını göstermiştir
