Normoksik ve Hipoksik Koşullarda Uygulanan Yüksek Şiddetli İnterval Antrenman Programının Kan Yağ Parametreleri Üzerine Etkisi

Amaç: Bu çalışmanın amacı normobarik ortamda, normoksik ve hipoksik koşullarda 8 hafta boyunca uygulanan yüksek şiddetli interval antrenmanın (HIIT) kan yağları üzerindeki etkisini incelemektir. Metod: 16 katılımcı rassal olarak normoksi ve hipoksi gruplarına ayrılmışlar ve sonrasında her iki grupta normobarik ortamda, normoksik ve hipoksik koşullarda (2500m) 8 haftalık yüksek şiddetli interval antrenmana tabi tutulmuşlardır. Hipoksik koşul, Hypoxicasubmit II egzersiz paketi (USA) ile sağlanmıştır. Antrenman programı öncesinde katılımcıların yaşları, boy uzunlukları ve vücut ağırlıkları tespit edilmiştir. HIIT, wingate stili bisiklet antrenmanı şeklinde 8 hafta, haftada 3 gün, gün aşırı olmak üzere, 4 tekrar x 30 sn. ile başlayıp her iki haftada 1 tekrar artırılarak 7 tekrar x 30 sn. ile sonlandırılacak şekilde ve 4 dk.’lık dinlenme aralıklarıyla uygulanmış ve katılımcılardan yapabileceğinin en iyisini yapması istenmiştir. Trigliserid (TG), yüksek yoğunluklu lipoprotein (HDL), düşük yoğunluklu lipoprotein (LDL), çok düşük yoğunluklu lipoprotein (VLDL) ve total kolesterol (TOTKOL) analizi için katılımcılardan antrenman öncesi, 4. ve 8. haftalarda kan örnekleri alınmıştır. İstatistiksel değerlendirmelerde SPSS 22 yazılım programıyla yapılmıştır. Hipoksinin ve HIIT’in etkileri Tekrarlı Ölçümlerde İki Yönlü ANOVA yöntemi ile değerlendirilmiş ve tüm veriler p<0.05 anlamlılık düzeyinde analiz edilmiştir.Sonuç: Çalışmanın en önemli bulgusu HIIT antrenmanlarının normoksik veya hipoksik şartlarda uygulanması kan yağları üzerinde herhangi bir farka neden olmadığını göstermiştir (p>0,05). Ayrıca HIIT antrenmanlarının, hem normoksik ve hemdehipoksik şartlarda uygulanması kan yağ profili üzerinde pozitif etkide bulunduğu tespit edilmiştir (p<0.05).

TheEffect of High Intensity Interval Training Programme in Blood Lipid Parameters on Normoxic and Hypoxic Conditions

Purpose :The aim of the present study was to examine the effect of 8-week high intensity interval training (HIIT) on blood lipid parameters on normoxic and hypoxic conditions in the normobaric environment. Methods :16 participants were randomly assigned to normoxic or hypoxic groups and then they were subjectsto 8-week highintensity interval training on normoxic and hypoxic conditions (2500 m.) in the normobaric environment. The hypoxic conditions were provided with Hypoxica Submit II exercise package (Made in USA). The heights, weights and blood samples of participants were taken before the training programme. HIIT completed 8 weeks of Wingate style cycling training, 3 days/week, consisting of incremental repeats 4 to 7 every two weeks × 30s all-out effort with 4 min rests.The blood samples were taken before the training and 4.week and 8.week of training for analizing triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), very low density lipoprotein (VLDL) and total cholesterol (TOTKOL). Statistical evaluation was conducted by using SPSS 22 software program. TheTwo-Way Repeated Measures ANOVA was used to determine the effects of hypoxia and HIITand all data were analyzed at significance level of p<0.05.Results : The main findings of the study was no differences applying HIIT training on hypoxic or normoxic conditions on blood lipids (p>0,05). Also, HIIT lead to positive effects on the blood lipid parameters on normoxic and hypoxic conditions (p<0.05).
