The players were classified into four different positions: goalkeepers (n=4), defenders (n=9), midfielders (n=12), and forwards (n=2). The lower extremity strength of the participants was assessed using the 6-Repetition Maximum (6RM) Leg Press and 6RM Squat tests, while their jumping performance was measured through the Squat Jump (SJ), Countermovement Jump (CMJ), and Horizontal Jump (HJ) tests. One-way analysis of variance (ANOVA) and Tukey post-hoc tests were applied for data analysis.

                            <p>Bu çalışma, futbolcularda oyun pozisyonlarına göre alt ekstremite kuvveti ve sıçrama performansındaki farklılıkları belirlemeyi amaçlamaktadır. Denizlispor Futbol Kulübü’nden 27 sağlıklı erkek futbolcu araştırmaya dahil edilmiştir (yaş: 20±3,74 yıl, boy: 181,22±11,12 cm, kilo: 67,78±13,97 kg). Oyuncular dört farklı pozisyona göre sınıflandırılmıştır: kaleci (n=4), defans (n=9), orta saha (n=12) ve forvet (n=2). Alt ekstremite kuvveti 6 Tekrar Maksimum (6TM) Leg Press ve 6TM Squat testleriyle değerlendirilmiş, sıçrama performansı ise Squat Jump (SJ), Countermovement Jump (CMJ) ve Horizontal Jump (HJ) testleriyle ölçülmüştür. Veriler tek yönlü varyans analizi (ANOVA) ve Tukey post-hoc testleri ile analiz edilmiştir. Bulgular, forvet ve orta saha oyuncularının kaleci ve defans oyuncularına kıyasla daha yüksek bacak kuvveti ve sıçrama performansına sahip olduğunu göstermiştir. Özellikle horizontal sıçrama mesafesinde forvetler belirgin üstünlük sergilemiştir. Kalecilerin ise tüm testlerde en düşük değerleri elde ettiği görülmüştür. Bu sonuçlar, oyun pozisyonlarının fiziksel kapasite üzerinde belirleyici olduğunu ve pozisyona özgü kuvvet ile sıçrama özelliklerinin geliştiğini ortaya koymaktadır. Çalışmanın sınırlılıkları arasında küçük örneklem büyüklüğü ve bazı pozisyon gruplarındaki dengesiz dağılım (özellikle forvetler) yer almaktadır. Bununla birlikte bulgular, antrenman planlamasında pozisyona özgü kuvvet ve kondisyon programlarının önemini vurgulamaktadır. Antrenörler, defans oyuncularına patlayıcı güç odaklı, forvetlere dikey sıçrama ve sprint hızına yönelik, orta sahalara ise kuvvet-endurans dengesini geliştiren programlar uygulamalıdır. Kaleciler için ise patlayıcı kuvvet ile çeviklik antrenmanlarının bütünleştirilmesi önerilmektedir.</p></trans-abstract>
