Çeşitli dayanıklılık protokollerine verilen metabolik cevapların karşılaştırılması

Çalışmanın amacı laboratuvar ve saha ortamında uygulanan çeşitli dayanıklılık protokollerine verilen metabolik cevapların karşılaştırılması ve testlerden elde edilen maksimum oksijen tüketimi $(VO_{2maks})$ değerlerinin testlerde kat edilen toplam mesafe ile ilişkilerinin incelenmesidir. Çalışmaya genç takımlarda oynayan toplam 30 futbolcu katılmıştır. Araştırma grubundaki sporculara koşu bandı (KB), mekik (M), dairesel mekik (DM), modifiye mekik (MM) ve dairesel modifiyemekik(DMM) olmak üzere beş farklı dayanıklılık protokolü uygulanmıştır. Protokollere submaksimum ve maksimum koşu hızlarında verilen kan laktat (LA), oksijen tüketimi $(VO_{2}),$ kalp atım hızı (KAH) ve algılanan zorluk düzeyi (AZD) değerleri belirlenmiştir. Protokollere verilen metabolik cevaplar tekrarlı ölçümlerde varyans analizi ile karşılaştırılmıştır. İkili grup karşılaştırmalarında ise LSD testi kullanılmıştır.Protokoller arasındaki ilişkiler ise Pearson korelasyon katsayısıyla incelenmiştir. Submaksimum koşu hızlarında M ve MM testlerine yerilen LA, V02, KAH ve AZD cevaplan KB, DM ve DMM testlerinden yüksek bulunmuştur (p

Comparison of metabolic responses to various endurance protocols

The purpose of this study was to compare metabolic responses to various endurance tests administered in laboratory and field conditions, and to consider relationship between maximal oxygen consumption $(VO_{2max})$ and distance covered during tests. Thirty-players playing at young-teams participated to study. The players were performed treadmill (T), shuttle-run (SR), circular shuttle-run (CSR), modified shuttle-run (MSR) and circular modified-shuttle-run (CMSR) tests. Blood lactate (LA), oxygen consumption $(VO_{2}),$ heart rate (HR) and rate of perceived exertion (RPE) responses to protocols were determined. Comparison of metabolic response differences between protocols were made using repeated measures ANOVA. LSD test was applied to identify the point of differences. Relationships between protocols were considered using Pearson Correlation. LA, V02, HR and RPE responses to SR and MSR at submaximal running speeds were higher than T, CSR and CMSR (p
