This study aimed to evaluate VO2 max which is known as an important criteria of the aerobic performance by field and laboratory tests. Thirty athletes (15 female and 15 male) who have a current athletes license were recruited for this study. All of the athletes performed treadmill test (TT) which is known as the golden standard in evaluating VO2 max, a 20- m shuttle run test (SRT), and 12 minute Cooper test (CT), respectively. The VO2 max determined by a telemetrical portable ergospirometer in TT and SRT, on the other hand it was determined by a nomogram in CT. Also, blood lactate was taken before, right after, and 3 minutes after the tests. Paired sample t test and Pearson correlation coefficients test showed no statistical difference in VO2 max mean values of the TT, SRT and CT tests (p>0.05), but there was perfect positive correlation. Also, there were statistical differences on the blood lactate values taken right after the tests (p>0.05). This was valid for the blood lactate values which were taken in the 3rd minute after the tests of the men (p<0.05). With regards to women, statistical differences were found in blood lactate between TT - SRT, and also TT - CT tests (p<0.05), but no statistical difference was found between SRT- CT tests (p>0.05). Field tests which require low cost and do not need advanced equipment may be an alternative to laboratory tests which are costly and which require sophisticated equipment. However, it should be taken into consideration that laboratory tests are more preferable to validity and reliability of the field tests than the others.

Bu çalışmanın amacı, aerobik performansın önemli kriteri olan maksimal oksijen tüketiminin (MaksVO2) sporcularda, saha ve laboratuvar testleriyle değerlendirilmesidir. Çalışmaya aktif sporcu lisansına sahip 15 erkek ve 15 kadın sporcu katıldı. Tüm sporculara MaksVO2 belirlemede altın standart olarak kabul edilen laboratuvarda kademeli artan koşu bandı testi (KBT), sahada 20 m mekik koşusu testi (MKT) ve yine sahada 12 dakika Cooper testi (CT) yaptırıldı. KBT ve MKT’de maksVO2, telemetrik taşınabilir ergospirometre vasıtasıyla belirlenirken, CT’de nomogram yardımıyla elde edildi. Ayrıca, tüm testlerden önce, hemen sonra ve test bitiminden üç dakika sonra kan laktat değerleri ölçüldü. KBT, MKT ve CT sonucu elde edilen MaksVO2 değerleri ortalamalarının ikili karşılaştırılması sonucu istatistiksel olarak anlamlı fark gözlenmezken (p>.05), güçlü pozitif korelasyon tespit edildi. Tüm testlerden hemen sonra ölçülen kan laktat değerleri ortalamaları protokoller arası ikili karşılaştırıldığında istatistiksel olarak anlamlı bir farka rastlanmadı (p>.05). Test bitiminden üç dakika sonra erkek sporcuların kan laktat değerleri ortalamalarının ikili karşılaştırılması sonucu istatistiksel olarak anlamlı fark tespit edildi (p<.05). Kadın sporcularda ise, KBT ve MKT, KBT ve CT kan laktat değerleri ortalamalarının ikili karşılaştırılması sonucu istatistiksel olarak anlamlı fark tespit edilirken (p<.05), MKT ve CT kan laktat değerleri arasında istatistiksel olarak anlamlı fark bulunmadı (p>.05). Az maliyet gerektiren, gelişmiş donanıma ihtiyaç duymayan saha testleri, maliyetli ve gelişmiş donanım gerektiren laboratuvar testlerine alternatif olabilir. Ancak, saha testlerinin geçerlilik ve güvenirlilik çalışmaları için laboratuvar testlerinin daha çok tercih edildiği göz önünde bulundurulmalıdır.
