The aim of this study was to investigate the effects of French contrast training applied during the in-season period on vertical jump, change of direction, and repeated sprint performance in professional soccer players. A total of 22 professional players competing in the Turkish Trendyol 1st League (2025–2026 season) participated in the study. Participants were randomly assigned to an experimental group (n=11) and a control group (n=11). The experimental group performed French contrast training twice per week for six weeks in addition to regular team training, while the control group continued their routine training program. Performance measurements were conducted before and after the intervention using countermovement jump (CMJ), Illinois agility test, and a 10×30 m repeated sprint test. Data were analyzed using two-way repeated measures ANOVA. The results indicated significant improvements in vertical jump and change of direction performance in the experimental group compared with the control group (p.05). In conclusion, French contrast training appears to be an effective method for improving explosive power and change of direction ability during the in-season period in professional soccer players, while its effects on repeated sprint performance may be limited.

Bu çalışmanın amacı, profesyonel futbolcularda sezon içi dönemde uygulanan Fransız kontrast antrenman metodunun dikey sıçrama, çeviklik ve tekrarlı sprint performansı üzerindeki etkilerini incelemektir. Araştırmaya Trendyol 1. Lig 2025–2026 sezonunda mücadele eden profesyonel futbolculardan oluşan 22 sporcu katılmıştır. Katılımcılar rastgele yöntemle deney (n=11) ve kontrol (n=11) gruplarına ayrılmıştır. Deney grubuna altı hafta boyunca haftada iki gün Fransız kontrast antrenman programı uygulanırken kontrol grubu rutin takım antrenmanlarına devam etmiştir. Performans ölçümleri müdahale öncesi ve sonrası countermovement jump (CMJ), Illinois çeviklik testi ve 10×30 m tekrarlı sprint testi ile gerçekleştirilmiştir. Verilerin analizinde iki faktörlü tekrarlı ölçümler varyans analizi kullanılmıştır. Bulgular, deney grubunun dikey sıçrama ve çeviklik performansında kontrol grubuna kıyasla anlamlı gelişim gösterdiğini ortaya koymuştur (p.05). Sonuç olarak, Fransız kontrast antrenmanının profesyonel futbolcularda sezon içi dönemde patlayıcı güç ve çeviklik performansını geliştirmede etkili olduğu, ancak tekrarlı sprint performansı üzerinde sınırlı etki oluşturduğu söylenebilir.
