The Effect of Endurance Training in the Conditions of Normoxia and Hypoxia on Maximal Oxygen Consumption (VO2max) and Some Ventilator Parameters in Cross-Country Skiers

Abstract

Objective: Examination of the effect of endurance training in normoxia and hypoxia on maximal oxygen consumption (VO2 max) and some ventilator parameters in cross-country skiers. Materials and Methods: The study includes total 18subjects, 10 males and 8 females, who took part in the races at elite level, and practiced exercises for developing aerobic endurance on 6days a week. Totally 3 measurements were done during study, the first one of which was in Ankara (856 m), the second on the Mount Erciyes at the first day of acclimatization (2220 m, 4-6ºC) and the last one was again on Erciyes at the 7th day of acclimatization. All the tests were done at the same time of the day, 3hours after the lunch. Results: The conclusion statistical analysis; in the comparison three tests of females, significant differences were found among the first and the second VO2max scores at the level of p

Kayaklı- Koşucularda Dayanıklılık Egzersizlerinin Normoksi ve Hipoksi Koşullarında Maksimum Oksijen Tüketimi (MaxVO2) ve Bazı Solunum Parametreleri Üzerine Etkisi

Öz

Amaç: Kayaklı koşu sporcularında dayanıklılık egzersizlerinin, normoksi ve hipoksi koşullarında maksimum oksijen tüketimi (maxVO2) ve bazı solunum parametreleri üzerine etkisinin incelenmesidir. Gereç ve Yöntem: Çalışmaya, ulusal ve uluslararası düzeyde kayaklı koşu yarışmalarına katılan, haftanın 6 günü submaksimal şiddette aerobik dayanıklılığı geliştirici egzersiz yapan 10 erkek ve 8 bayan toplam 18 sporcu gönüllü olarak katılmıştır. Ölçümler toplam üç kez ve ilki Ankara'da (856 m rakımda), ikincisi Erciyes Dağında (2220 m. rakımda) ilk gün, üçüncüsü de dağda kalınan 7. günde öğleden sonra, hep aynı saatlerde ve yemekten ortalama 3 saat kadar sonra gerçekleştirilmiştir. Ölçümler Kayseri Erciyes Kayak Merkezinde 2220 m yükseklikte, 4-6 ºC hava sıcaklığında yapılmıştır. Verilerin istatistiksel analizi SPSS 10.0 programı kullanılarak yapılmıştır. Bulgular: Yapılan istatistiksel analiz sonucunda; kız sporcuların üç ölçümü karşılaştırıldığında sadece maxVO2 değerlerinde 1. ve 2. ölçümler arasında p
