The Effect of Unilateral Plyometric Training on Dynamic Balance and Knee Proprioception in Elementary School Students

Abstract

The aim of this study is to investigate whether unilateral plyometric training has an effect on dynamic balance ability and knee proprioception, and if so, to what degree. Sixteen female volleyball players aged 12-14 participated in the study. These 16 athletes, randomly selected from elementary school students, were divided into two groups: 8 in the experimental group and 8 in the control group. The experimental group underwent an 8-week unilateral plyometric training program. The control group continued their volleyball training. Pre-test and post-test measurements were taken before and after the study. Measurements included the Y balance test for dynamic balance and knee joint extension measurements at 30°, 45°, and 60° using a digital goniometer for knee prop-rioception. The groups were found to be normally distributed. The Independent Samples T-test was applied for two variables, and the One-Way ANOVA test was applied for more than two variables. There was a statistically significant difference in the Y Balance test values in the study group (p<0.05). There was a statistically significant difference in the knee proprioception 45° test values (p<0.05). The final test results for knee proprioception 45° were significantly higher. There is no statistically significant difference between the pre/post-test levels of the other variables (p>0.05). In light of the findings obtained in the study, it was concluded that the unilateral plyometric training protocol is effective on dynamic balance and knee proprioception, as the dynamic balance and knee propri-oception measurement results detected in the pre-tests showed improvement in the post-tests.

İlköğretim Çağındaki Öğrenciler Üzerinde Yapılan Unılateral Pliometrik Antrenmanın Dinamik Denge ve Diz Propriosepsionu Üzerine Etkisi

Abstract

Bu çalışmanın amacı, tek taraflı pliometrik antrenmanın dinamik denge yeteneği ve diz propriyosepsiyonu üzerinde bir etkisi olup olmadığını ve varsa, bu etkinin ne derece olduğunu araştırmaktır. Çalışmaya 12-14 yaşları arasında 16 kadın voleybolcu katılmıştır. İlkokul öğrencilerinden rastgele seçilen bu 16 sporcu, 8'i deney grubu ve 8'i kontrol grubu olmak üzere iki gruba ayrılmıştır. Deney grubu 8 haftalık tek taraflı pliometrik antrenman programına tabi tutuldu. Kontrol grubu voleybol antrenmanlarına devam etti. Çalışma öncesinde ve sonrasında ön test ve son test ölçümleri yapıldı. Ölçümler arasında dinamik denge için Y denge testi ve diz propriyosepsiyonu için dijital gonyometre kullanılarak 30°, 45° ve 60°'de diz eklemi ekstansiyon ölçümleri yer aldı. Grupların normal dağılım gösterdiği tespit edildi. İki değişken için Bağımsız Örneklemler T-testi, ikiden fazla değişken için Tek Yönlü ANOVA testi uygulanmıştır. Çalışma grubunda Y Denge testi değerlerinde istatistiksel olarak anlamlı bir fark vardı (p<0,05). Diz propriyosepsiyonu 45° test değerlerinde istatistiksel olarak anlamlı bir fark vardı (p<0,05). Diz propriyosepsiyonu 45° için son test sonuçları anlamlı olarak daha yüksekti. Diğer değişkenlerin test öncesi/sonrası düzeyleri arasında istatistiksel olarak anlamlı bir fark yoktur (p>0,05). Çalışmada elde edilen bulgular ışığında, tek taraflı plyometrik antrenman protokolünün dinamik denge ve diz propriyosepsiyonu üzerinde etkili olduğu sonucuna varılmıştır, zira test öncesi ölçümlerde tespit edilen dinamik denge ve diz propriyosepsiyonu ölçüm sonuçları test sonrası ölçümlerde iyileşme göstermiştir.
