DO PNF EXERCISES HAVE ACUTE EFFECT ON BALANCE AND JUMPING PERFORMANCE IN VOLLEYBALL PLAYERS?

Öz

In this study, it was aimed to determine the acute effect of PNF exercises on balance and jump performance. The sample group of the study was Sports Science students 12 male (age: 20.83±1.11 years, Height: 184.41±5.45 cm, Body weight: 72.16±8.03 kg), 12 female (age: 19 years old) .83±0.71years, Height: 168.00±7.95cm, Body weight: 58.66±5.24kg) constituted a total of 24 participants. 5 minutes of jogging and proprioceptive neuromuscular facilitation (PNF) exercise were applied to the participants, and then CMJ (Countermovement Jump) test for vertical jump performance and SJ (Squad Jump) test were applied to determine balance performance, static and dynamic balance test were applied. SPSS 25 statistical package program was used to evaluate the obtained data. According to the results of the evaluation, a significant difference was found at the level of p<0.05 in the intragroup comparisons of the CMJ and SJ values of female volleyball players, and at the level of p<0.05 in the SJ value of male volleyball players. In the static balance in-group comparisons of female volleyball players, a significant difference was found at the p<0.05 level in the mean right-left swing speed, and at the p<0.05 level in the standard right-to-left swing value of the male volleyball players. In the dynamic balance data, in women; A significant difference was found at p<0.05 level in dynamic balance performance, right swing area, right external swing area and right swing reaction time values. As a result, it can be said that PNF exercises contribute positively to the vertical jump and balance performance, and the implementation of these exercises in training and competitions will contribute to the performance of the athletes.

PNF EGZERSİZLERİNİN VOLEYBOLCULARDA DENGE VE SIÇRAMA PERFORMANSI ÜZERİNE AKUT ETKİSİ VAR MIDIR?

Öz

Bu çalışmada PNF egzersizlerinin denge ve sıçrama performansına akut etkisinin belirlenmesi amaçlandı. Araştırmanın örneklem grubunu Spor Bilimleri öğrencileri 12 erkek (yaş: 20.83±1.11 yıl, Boy: 184.41±5.45 cm, Vücut ağırlığı: 72.16±8.03 kg), 12 kadın (yaş: 19.83±0.71yıl, Boy: 168.00±7.95cm, Vücut ağırlığı: 58.66±5.24kg) toplam 24 katılımcı oluşturdu. Katılımcılara 5 dakika hafif tempo koşu ve Proprioseptif Nöromusküler Fasilitasyon (PNF) egzersizi uygulandı ve sonrasında dikey sıçrama performansı için CMJ (Countermovement Jump) testi ve SJ (Squad Jump) testi denge performansını belirlemek için statik ve dinamik denge testi uygulandı. Elde edilen verileri değerlendirmesinde SPSS 25 istatistik paket programı kullanıldı. Değerlendirme sonucuna göre kadın voleybolcuların CMJ ve SJ değerlerinin grup içi karşılaştırmalarında p<0.05 düzeyinde, erkek voleybolcularda SJ değerinde ise p<0.05 düzeyinde anlamlı farklılık bulunmuştur. Kadın voleybolcuların statik denge grup içi karşılaştırmalarında sağa-sola ortalama salınım hızında p<0.05 düzeyinde, erkek voleybolcuların sağa sola standart salınım değerinde p<0.05 düzeyinde anlamlı farklılık bulunmuştur. Dinamik denge verilerinde ise Kadınlarda; dinamik denge performansı, sağ salınım alanı, sağ dış salınım alanı ve sağa salınım reaksiyon zamanı değerlerinde p<0.05 düzeyinde anlamlı farklılık bulunmuştur. Sonuç olarak PNF egzersizlerinin dikey sıçrama ve denge performansına olumlu katkı yaptığı antrenör ve sporculara bu egzersizlerin antrenman ve müsabakalarda uygulanması sporcuların performansına katkı sağlayacağı söylenebilir.
