Abstract (2. Language): 
Hypoxia is a condition where partial oxygen pressure is low, that is why altitude creates a hypoxic environment. In response to hypoxic stress, mainly hypoxia inducable factor-1 alpha (HIF-1 a) level increases and carbohydrate related genes are activated by HIF-1 a mak¬ing the physiological adaptation to altitude easy. Understanding the effects of hypoxia oncarbohydrate metabolism and exercise performance would be useful in terms of using car¬bohydrates for the people who are exposed to altitude for various reasons (athletes, moun¬taineers, troops and tourists).
Abstract (Original Language): 
Hipoksi, oksijen parsiyel basıncının (PO2) düşük olduğu durumları tanımlar, bu yüzden yükselti hipoksik bir ortam yaratmaktadır. Hipoksik strese cevap olarak, başta hipoksi ile indüklenen faktör-1 alfa (HIF-1a, hypoxia inducable factor-1 alpha) düzeyi artmakta ve kar¬bonhidrat (CHO) metabolizması ile ilgili genleri de aktive ederek hipoksiye fizyolojik adapta¬syonu kolaylaştırmaktadır. Yükseltinin CHO metabolizması ve egzersiz performansı üzerindeki etkilerinin bilinmesi, değişik amaçlarla yükseltide bulunmak zorunda kalan kişilere (sporcular, dağcılar, işçiler, askerler, turistler) CHO'ların kullanımı ile ilgili yararlar sağlaya¬caktır.
