Abstract (2. Language): 
The purpose of this study was to examine the validity and the reliability of the modified progressive shuttle run (MMK), which is designed to be used in measuring maximal aerobic power and anaerobic threshold running velocity.10 female handball players (Age: 21.2±1.5 years, height: 167.7±9.5 cm, body weight:65.3±7.1 kg) from a first division team were volunteered for the study. The subjects were taken to three measurements with one week interval between the measures During the first two weeks two measurements, namely MMK and Progressive Shuttle Run tests (MK) were given in random order. During the third week, the MMK was given second time to randomly chosen 7 subjects. MMK was run at 8, 10, 11, and 12 km/h velocities for 3 minutes at each speed with one minute rest in between them. Heart rate (HR) was recorded by Polar watches, and by having a drop of blood from an ear lobe whole blood lactic asid (LA) analysis was made. In MMK test retest measures there was no statistically significant difference between heart rate, lactic asid, anaerobic threshold (AT) and anaerobic threshold HR (AT-HR) values. Except for the LA, all the other test and retest results showed significant correlation (p<0.05). Although the test retest results showed high correlation at low velocities, the correlation was low at higher velocities. There was no correlation between the post test LA results of MK and MMK tests (r=0.14, p>0.05) AT velocity, and AT-HR values obtained from MMK showed no correlation with the number of shuttle runs obtained from MK (r=0.737, p>0.05 and r=0.532, p>0.05). Similarly the HR values obtained from MMK and MK at corresponding velocities, although there was no difference, there was no correlation between them. MMK can be used in determination of HR and LA at different running velocities. It has been concluded that although the MMK test was reliable the metabolic responses obtained were different than the MK test

Abstract (Original Language): 
Bu çalışmanın amacı, takım sporlarında maksimal aerobik gücün ve anaero¬bik koşu hızının belirlenmesinde kullanılması düşünülen Modifiye Mekik Koşusu (MMK) testinin güvenirliği ve geçerliğinin incelenmesidir. Birinci ligde oynayan 10 bayan hentbol oyuncusundan oluşan araştırma grubuna (yaş: 21.2±1.5 yıl; boy: 167.7±9.5 cm; vücut ağırlığı: 65.3±7.1 kg) birer hafta ara ile üç test yapılmıştır, ilk iki hafta sporculara rastgele sıra ile mekik koşusu (MK) ve MMK testleri uygulanmıştır Üçüncü hafta rastgele olarak seçilen 7 sporcu ikinci kez MMK testine girmişlerdir. MMK; 8, 10, 11 ve 12 km/s hızda, birer dakika dinlenme aralıklarıyla 3 dk'lık koşu hızlarında yapılmıştır 3 dk'lık koşularda kalp atım hızları (KAH) Polar saatleriyle kayıt edilmiş, dinlenme aralıklarına kulak memesinden alınan bir damla kanla tam kan laktik asit değerine bakılmıştır. MMK testinde ölçülen test-retest kalp atım hızı (KAH), laktik asit (LA), ana¬erobik eşik (AE) ve anaerobik eşik KAH (AE-KAH) değerleri arasında istatistiksel olarak anlamlı bir fark bulunmamıştır LA cevapları hariç, diğer tüm değişkenlerin test-retest korelasyon katsayıları önemli derecede yüksektir (p<0.05). Düşük hız-lardaki LA cevapları arasındaki korelasyon katsayısı yüksek iken, yüksek hızlarda düşük bulunmuştur. MK ile MMK egzersiz sonrası LA cevapları arasında anlamlı bir ilişki saptanmamıştır (r=0.14;p>0.05). MMK'dan elde edilen AE koşu hızı ve AE-KAH ile MK'-da ölçülen mekik sayısı arasındaki ilişkiler sırasıyla r=0.737; p>0.05 ve r=0.532; p>0.05 gibi orta derecede olmakla beraber anlamlı değildir. Aynı şekilde, MMK'-da her koşu hızında ölçülen KAH ile MK'da karşılık gelen hızlarda ölçülen KAH arasında fark olmamakla beraber, anlamlı bir ilişki saptanmamıştır. MMK, farklı hızlarda LA ve KAH tepkisini ölçmek için kullanılabilecek bir testtir. MMK testinin güvenilir ancak yarattığı metabolik cevaplar açısından MK'dan farklı olduğu söylenebilir.
