VERİLİ ANTRENMAN ŞİDDETLERİNDE YAPILAN EGZERSİZLERE VERİLEN METABOLİK YANITLAR

Öz

Bu çalışmanın amacı, verili antrenman şiddetlerinde yapılan egzersizlerde, kalp
atım hızı (KAH), kan laktat konsantrasyonu ([La]) ve oksijen tüketimi (VO ) 2
parametrelerinde ortaya çıkan farklılıkları saptamaktır. Çalışmaya, düzenli olarak
antrenman yapan yedi yol, dört dağ bisikletçisi katıldı (yaş: 25,2±6,2 yıl, boy: 175,1±5,1
cm, vücut ağırlığı: 70,4±7,3 kg). Denekler, test-tekrar test VO ve laktat testi (LT), birer 2maks
kez 2,0 (SŞE-2), 3,0 (SŞE-3) ve 4,0 (SŞE-4) mM kan [La] karşılık gelen sabit şiddetli
egzersizlerde (SŞE), [La] ±1 mM değişene kadar veya 30 dk egzersiz yaptılar. Testler
sırasında portatif O analizörü (Cosmed K4b2, Italy) ile VO ve KAH, her üç dakikada bir 2 2
kulak memesinden alınan kapiller kandan YSI 1500 laktik asit analizörü ile [La] ölçüldü.
Test, tekrar-test güvenirlik katsayısı tüm değişkenlerde 0,92'den büyüktür. Deneklerin
tümü SŞE-2 testini tamamladı, SŞE-3 testini dört denek, SŞE-4 testini iki denek
tamamlayabildi. SŞE-3'te yanıt (Y) KAH ile kestirim (K) KAH ve SŞE-4'te incelenen tüm
parametrelerde, egzersize verilen yanıt ve kestirilen değerler arasındaki fark anlamlı
bulundu (p < 0,05). Sonuç olarak, heterojen yapılı bir denek grubunda 3,0 ve 4,0 mM
[La]'na denk gelen antrenman şiddetlerinde yapılan uzun süreli egzersizlerdeki çalışma
süresi, KAH, VO ve VO'ın kullanılan yüzdesi bireysel olarak değişmekte ve bireyler 2 2maks
arasında farklı metabolik zorlanmalar yaratabilmektedir. Buradan hareketle, bireysel
cevaplar üzerinden iş yükü belirlenmesinde verili bir antrenman şiddetine verilen cevap
ve çalışma süresinin belirlenmesi önemlidir.
