Abstract

Although the highest power output to elicit peak O 2 consumption ( V O 2 peak ) (aerobic limit power; ALP) is an important boundary which separates severe and extreme exercise domain and it needs several constant-load tests to estimate an athlete’s individual ALP. The purpose of this study was to suggest an approach to predict the athletes’ ALP in a single test session. 12 well-trained cyclists ( V O 2max : 64.7±4.1 mL∙min-1∙kg-1 and peak power output (PPO): 374.1±65.7 W) volunteered for this investigation. Ramp incremental test was performed (+1 W·2 s-1) to determine V O 2 peak , and the final power output at the end of the test (FP) was evaluated with and without mean response time correction ( FP MRT and FP MRT , respectively). Constant-load exercises were performed to identify V O 2 max and PPO. Then, athletes’ ALP (the highest power output giving a V O 2 value closer to V O 2 max more than 5%) levels were detected by 15-W intervals with constant-load exercises in separate days. Difference between FP MRT and ALP was not significant (435.2±50.8 vs. 435.4±62.5 W, p=0.968, respectively). Bland Altman showed high agreement between the methods (Bias=–0,20±17,6 W; p=0.968). FP MRT was corresponded to 117.7±8.8% of PPO, while ALP was corresponded to 117.1±7.37% of PPO (p=0.00). The highest 15-s V O 2 means revealed from ramp incremental test were similar to V O 2 responses obtained from the ALP (62.3±4.9 vs. 61.5±4.3 mL∙min-1∙kg-1; p=0.119; and 96.2% vs. 95% V O 2 max , respectively). In conclusion, instead of several exhausted test sessions in separate days, a ramp incremental test which underestimates the V O 2 max may be a practical method to predict the ALP and its V O 2 response in a single test session by a ramp incremental test.

Özet

Zirve O2 tüketim düzeyi ( VO 2pik ) veren en yüksek güç çıktısı (aerobik limit güç; ALG) şiddetli ve aşırı egzersiz alanlarını ayıran önemli bir eşiktir ve sporcularda bireysel bir ALG belirleyebilmek için çok sayıda sabit yüklü tüketici test yapmak gerekmektedir. Bu çalışmanın amacı; sporcuların ALG’lerini tek bir seansta belirleyebilecek bir yaklaşım önermektir. Araştırmaya iyi antrene 12 bisiklet sporcusu katılmıştır ( V O 2maks 64,7±4,2 mL∙dk-1∙kg-1; Zirve Güç (ZG): 374,1±65,7 W). VO 2pik düzeyinin belirlenmesi için lineer yük artışlı (ramp) testler uygulatılmıştır (+1 W·2 s-1) ve protokollerin sonunda ulaşılan final güç üretim değerleri (FG) ortalama yanıt zamanı ( mean response time : MRT) düzeltmesi uygulanmadan ( FG MRT ) ve uygulanarak ( FG MRT ) değerlendirilmiştir. Sporcuların V O 2maks ’ı ve bu değeri veren ZG değerleri, doğrulama testleri uygulanarak bulunmuştur. Devamında sporcuların ALG ( V O 2maks ’a %5’ten daha yakın V O 2 değeri veren en yüksek güç çıktısı) değerleri, 15 W’lık intervallerle bitkinlikle sonlanan sabit yüklü testler yoluyla ayrı günlerde taranmıştır. FG MRT ile ALG değerleri arasındaki fark anlamlı değildir ( FG MRT : 435,2±50,8; ALG: 435,4±62,5 W, p=0,968). Bland-Altman sonuçları yüksek uyum göstermiştir (Bias=0,20±17,6 W; p=0,968). FG MRT , gerçek ZG’nin %117,5±8,8’ine karşılık gelirken, belirlenen ALG değeri ZG’nin %117,1±7,37’sine karşılık gelmiştir (p=0,759). Diğer yandan ramp testinden elde edilen en yüksek 15-s V O 2 ortalamaları da ALG yükündeki V O 2 yanıtlarıyla benzerdir ( Ramp Test: 62,3±4,9 ml∙dk-1∙kg-1, %96,2; ALG: 61,5±4,3 ml∙dk-1∙kg-1, %95; p=0,119 ). Sonuç olarak, ALG’yi belirleyebilmek için ayrı günlerde çok sayıda bitkinlikle sonlanan test yapmak yerine, tek seansta bir ramp test uygulamasının V O 2maks ’ı düşük tahmin ettiği ancak ALG’yi ve bu değere karşılık gelen V O 2 yanıtını belirleyebilmenin oldukça pratik bir yöntemi olabileceği bulunmuştur.
