Abstract

Bu araştırma, İstanbul Rumeli Üniversitesi'nde yüzme dersi alan öğrencilere uygulanan 4 haftalık Dinamik Nöromüsküler Stabilizasyon (DNS) egzersizlerinin serbest stil sprint hızına ve core stabilizasyonuna etkilerini incelemektedir. Çalışma, ön test-son test modeline dayanan deneysel bir tasarım kullanarak gerçekleştirilmiştir. Toplamda 10 kadın ve 18 erkek olmak üzere 28 öğrenci bu çalışmaya katılmıştır. Öğrencilerin atletik performanslarını ölçmek için "Prone Extension Test" ve "Leg Lowering Test" adlı iki farklı test uygulanmıştır. DNS egzersiz programı sonrasında, katılımcıların 25 metre serbest stil sprint süreleri ve core stabilizasyon kabiliyetleri değerlendirilmiştir. Veri analizi için SPSS 25.0 yazılımı kullanılmış ve Shapira-Wilk normallik testi ile başlanıp, sonrasında Wilcoxon testi ile devam edilmiştir. Anlamlılık düzeyi p<0.05 olarak belirlenmiştir. İstatistiksel analiz sonuçlarına göre, DNS egzersizlerinin core stabilizasyonu üzerinde "Prone Extension Test" ile ölçüldüğünde anlamlı bir etkisi görülmemiş, ancak 25 metre sprint süreleri ve "Leg Lowering Test" sonuçları üzerinde anlamlı iyileşmeler saptanmıştır (p<0.05). Bu bulgular, DNS egzersizlerinin yüzme performansı üzerindeki pozitif etkilerini göstermekte ve bu tür antrenmanların yüzücülerin serbest stil sprint yeteneklerini artırabileceğine işaret etmektedir. Araştırmanın sonuçları, yüzme branşında DNS egzersizlerinin kullanımının ve etkilerinin daha detaylı incelenmesini önermektedir. Bu sayede, antrenörler ve spor bilimcileri, atletik performansı artırmada daha etkili yöntemler geliştirebilir.

The Effects of a 4-Week DNS Exercise Program on Swimming Times and Core Stabilization of Students in the Faculty of Sports Sciences

Abstract

This study investigates the effects of a four-week Dynamic Neuromuscular Stabilization (DNS) exercise program on freestyle sprint speed and core stabilization among students enrolled in swimming courses at Istanbul Rumeli University. The research was conducted using an experimental design based on a pre-test and post-test model. A total of 28 students, comprising 10 females and 18 males, participated in the study. To measure the athletes' performance, two distinct tests, the "Prone Extension Test" and the "Leg Lowering Test," were administered. Following the DNS exercise regimen, the participants' 25-meter freestyle sprint times and core stabilization capabilities were evaluated. Data analysis was performed using SPSS 25.0 software, starting with the Shapiro-Wilk normality test, followed by the Wilcoxon test. The level of significance was set at p<0.05. Statistical analysis revealed that while the DNS exercises did not show a significant effect on core stabilization as measured by the "Prone Extension Test," there were significant improvements in the 25-meter sprint times and "Leg Lowering Test" results (p<0.05). These findings demonstrate the positive effects of DNS exercises on swimming performance, suggesting that such training could enhance swimmers' freestyle sprint capabilities. The results recommend further detailed examination of the use and effects of DNS exercises in the swimming discipline. This could enable coaches and sports scientists to develop more effective methods to enhance athletic performance
