The Effect of Nordic Hamstring Exercise on Sprint and Jumping Performance in Male Soccer Players

Öz

Purpose: The aim of this study is to investigate the effect of nordic hamstring exercise application on sprint and jumping performances in male football players. Method: A total of 20 athletes (15-16 years old) participating in the U-17 team of a professional football club participated in the study voluntarily. The athletes participating in our study were randomly divided into two groups as control group (n=10) and training group (n=10). With the anthropometric measurements of the athletes, the parameters of the 30m sprint and vertical jump were measured as a pre-test at the beginning of the study and as a post-test at the end. After the pre-test values are taken, the athletes in the training group are in addition to their usual weekly routine football training; They have been following the Nordic hamstring exercise protocol for eight weeks, 2-3 days a week. The control group, on the other hand, continued their normal routine football training and did not do any additional training. At the end of the eight-week application, the final test application was made and the study was terminated. In the comparisons of the data within the group, the t-test was used in the dependent groups and the t-test was used in the independent groups for the comparisons between the groups. Results: As a result of the statistical analysis of the data, it was determined that there were statistically significant improvements in the sprint time and vertical jump height values of the training group (p<0.05). In addition, it was determined that there was a significant difference between the pretest and post-test values of the sprint performance of the control group, but there was not the same significant difference in jumping performance. Conclusion: In this study, it can be said that the Nordic hamstring exercise protocol applied to young football players showed significant improvements in some performance parameters. It is recommended that coaches give more space to nordic hamstring exercises in their training programs, which have an important effect on both preventing athletes' injuries and improving athletic performance.

Erkek Futbolcularda Nordik Hamstring Egzersizinin Sprint ve Sıçrama Performansına Etkisi Sprint ve Sıçrama Performansına Etkisi

Öz

Amaç: Bu çalışmanın amacı, erkek futbolcularda nordik hamstring egzersiz uygulamasının sprint ve sıçrama performansları üzerindeki etkisini incelemektir. Yöntem: Çalışmaya, profesyonel bir futbol kulübünün U-17 takımında yer alan toplam 20 sporcu (15-16 yaş) gönüllü olarak katılmışlardır. Çalışmamıza katılan sporcular, kontrol grubu (n=10) ve antrenman grubu (n=10) olmak üzere randomize şekilde iki gruba ayrılmıştır. Sporcuların antropometrik ölçümleri ile 30m sprint ve dikey sıçrama parametreleri çalışmanın başında ön-test ve sonunda ise son-test olarak ölçülmüştür. Ön-test değerleri alındıktan sonra antrenman grubundaki sporcular, haftalık olağan rutin futbol antrenmanlarına ek; sekiz hafta, haftada 2-3 gün Nordik hamstring egzersiz protokolünü uygulamıştır. Kontrol grubu ise olagan rutin futbol antrenmanlarına devam etmiş ve bunun dışında ilave antrenman yapmamıştır. Sekiz haftalık uygulama sonunda son-test uygulaması yapılmış ve çalışma sonlandırılmıştır. Verilerin grup içindeki karşılaştırmalarında bağımlı gruplarda t testi, gruplar arasındaki karşılaştırmalarda ise bağımsız gruplarda t testi kullanılmıştır. Bulgular: Verilerin istatistiksel analizi sonucunda antrenman grubunun, sprint zamanı ve dikey sıçrama yüksekliği değerlerinde istatistiksel olarak anlamlı gelişmeler olduğu belirlenmiştir (p<0.05). Ayrıca kontrol grubunun sprint performansının öntest-son test değerleri arasında anlamlı bir fark olduğu fakat sıçrama performansında aynı anlamlı farkın olmadığı belirlenmiştir. Sonuç: Bu çalışmada, genç futbolculara uygulanan, Nordik hamstring egzersiz protokolünün bazı performans parametrelerinde anlamlı gelişmeler gösterdiği söylenebilir. Antrenörlerin gerek sporcuların sakatlıklarının önlenmesinde gerekse sportif performansın arttırılmasında önemli etkisi olan nordik hamstring egzersizlerine kendi antrenman programlarında daha fazla yer vermeleri önerilmektedir.
