Amaç: Bir tekrar maksimalin (1 TM) %90'ında 5 tekrarlı 'leg press' hareketi ile yapılan ısınma uygulamalarının erkek futbolcularda çeviklik performansı üzerine olan etkisinin incelenmesidir. Gereç ve Yöntemler: Çalışmaya, yaş ortalaması 22,87±1,51 yıl, boy ortalaması 178,70±7,89 cm ve vücut ağırlığı ortalaması 74,54±8,75 kg olan 39 erkek futbolcu gönüllü olarak katıldı. Çalışmaya katılan futbolcular, rastgele örneklem yöntemi ile Çalışma Grubu (ÇG) (n=21) ve Kontrol Grubu (KG) (n=18) olmak üzere 2 farklı gruba ayrıldı. Tüm futbolcuların çeviklik performansını belirlemek için yapılan ilk test, koşu bandı üzerinde 8 km/saat hızda 5 dk'lık ısınmayı takiben 5 dk'lık pasif dinlenme sonrasında alındı. ÇG ve KG'yi oluşturan futbolcuların, 2. çeviklik testleri ilk testten 48 saat sonra yapıldı. İkinci testte, ÇG'deki futbolculara ilk testteki ısınma protokolünü takiben 1 TM'nin %90'ında 5 tekrarlı 'leg press' egzersizi yaptırıldı. 'Leg press' uygulamasından sonra 5 dk pasif dinlenme verildi ve futbolcular çeviklik testine tabi tutuldu. KG'deki futbolcular ise 2. çeviklik testinde de ilk testteki protokolün aynısını uyguladılar. Bulgular: Araştırmaya katılan futbolcuların, çeviklik testine ait sonuçlarının analizinde tekrarlı ölçümlerde ANOVA testi kullanıldı. Yapılan analiz sonucunda, farklı ısınma protokolüne tabi tutulan futbolcuların zamana bağlı çeviklik testine ait değerlerinde anlamlı farklılığa rastlandı (p=0,016). ÇG ve KG'deki futbolcuların ön-test-son-test değerleri arasındaki farklılığı belirlemede, basit etkiler analizine başvuruldu. Analiz sonucunda, ÇG ve KG'deki futbolcuların ön-test değerleri arasında anlamlı bir farklılığa rastlanmazken, ÇG'deki futbolcuların son-teste ait performans değerlerinde anlamlı bir artış görüldü (p=0,238; p=0,024). Sonuç: Bir TM'nin %90'ında 5 tekrarlı 'leg press' hareketi ile yapılan ısınmaların, futbolcuların çeviklik performansında anlamlı artışa neden olabileceği ifade edilebilir.

Objective: The effect of 5 repetitions of 90% of 1 repeated maximal voluntary contraction leg press-based warm-up protocol on agility performance in soccer players. Material and Methods: Thirty-nine soccer players (age: 22.87±1.51 yrs; height: 178.70±7.89 cm; weight: 74.54±8.75 kg) were volunteered to participate in this investigation. The athletes who participated in this study were randomly divided into two groups; Leg Press Warm-up Group (LP) (n=21) and Control Group (CG) (n=18). initial measurement values of agility test for all athletes was made followed by 5 minutes passive rest after 5 minutes warm-up at 8 km/h on treadmill. The second measurements of the soccer players were performed 48 hours after the first measurements. In the second measurement, leg press warm-up group were subjected to 5 repetitive leg press exercises at 90% of one-repetition maximum (1 RM) following the first measurement warm-up protocol. After leg press implementation, 5 minutes passive rest was given and the athletes were subjected to agility test again. The second measurements of the CG was obtained followed by 5 minutes passive rest after 5 minutes warm-up at 8 km/h on treadmill. Results: In analyzing the data, repeated measure analysis of variance (ANOVA) was conducted. The results indicated that significant time interactions were observed for agility test scores in the soccer players subjected to different warm-up protocols (p=0,016). Simple effects analysis were used to determine the difference between groups following by pre- and post-measurement process. As a result of analysis, while there was no significant difference between LP and CG group following by pre-test scores (p=0,238), a significant increase was observed in the LP group after the post-test scores (p=0,024). Conclusion: It can be stated that 5 repetitions of 90% of maximal voluntary contraction leg press-based warm-up may cause a significant increase in agility performance of soccer players.
