Özet
Son yıllarda anaerobik metabolizmanın fiziksel performansa olan etkisi üzerine ilgi gittikçe artmaktadır. Anaerobik metabolizmanın değerlendirilmesinde kullanılan Wingate testi (WT) non-invaziv olması, fazla donanım ve beceri gerektirmemesi ve güvenilirliğinin yüksek olması nedeniyle birçok laboratuvarda kullanılmaktadır. Bu çalışmada yaşlan 19-25 arasında olan 30 sağlıklı sedanter erkek tıp öğrenci sine 75 gr/kg ve 95 gr/kg yüklerde iki farklı WT uygulandı. Test sırasındaki oksijen tüketimleri (V02) "breath by breath" metodu ile ölçüldü, ölçülen V02 değerlerinden test süresince tüketilen toplam 02 miktarı ve yapılan toplam işteki aerobik katkılar hesaplandı. WT 75 için PP, MP ve Fi değerleri sırasıyla 592.5 ± 67.7 Watt, 466.4 ±51.7 Watt ve % 41.1 ± 8.7 bulundu. WT 95'de elde edilen güç değerleri ise sırasıyla 684.1 ± 94.8 Watt, 484.8 ± 61.7 Watt ve % 47.7 ± 10.4 idi. îki testin güç değerleri arasındaki farklar istatistiksel olarak anlamlı bulundu (sırasıyla p<0.001, p<0.05, p<0.01). Aerobik katkılar, mekanik verimlilik % 25 kabul edildiğinde, WT 75 için % 24.5 ± 4.7, WT 95 için % 23.7 ± 4.7 olarak hesaplandı. Aradaki fark istatistiksel olarak anlamlı bulunmadı. Bu denek grubu için en yüksek güç değerlerini veren optimal yükün 75 gr/kg ve 95 gr/kg arasında olduğu ve yüksek güç değerlerinin elde edildiği testlerdeki aerobik katkının daha düşük olabileceği düşünüldü.
The effect of the anaerobic metabolism to physical performance has received much deserved attention in recent years. Wingate test (WT) is non-invasive, need not much equipment and high skill to administer and reliable; so that, various laboratories have used it for the evaluation of anaerobic metabolism. In this study, 30 healthy and sedantery male medical students (aged 19-25 year- old) performed two different WT at 75 gr/kg and 95 gr/kg loads (WT 75, WT 95 respectively). Breath by breath oxygen consumption of the subjects was measured during the tests. The amount of total oxygen consumption and the aerobic contributions to the total work were evaluated for both tests. In WT 75, the values of peak power (PP), mean power (MP) and fatigue index (FI) were 592.5 ± 67.7 Watt, 466.4 ±51.7 Watt and % 41.1 ±8.7.respectively. Power outputs that obtained from WT 95 were 684.1 ± 94.8 Watt, 484.8 ± 61.7 Watt and % 47.7 ± 10.4, respectively. Difference between power outputs of the WT 75 and WT 95 were statistically significant (p<0.001, p<0.05, p<0.01, respectively). Assuming mechanical efficiency as 25 %, the aerobic contributions were evaluated as 24.5 ± 4.7 % for WT 75,and 23.7 ± 4.7 % for WT 95. Difference between aerobic contributions was found statistically insignificant. It was suggested that optimal load for eliciting maximal power outputs was between 75 gr/kg and 95 gr/kg for this subject group and much lower aerobic contribution values could be evaluated from the tests which maximal power outputs were obtained from.
