ACUTE EFFECT OF FOAM ROLLER APPLIED AT DIFFERENT FREQUENCY LEVELS ON FLEXIBILITY IN AMPUTEE PLAYERS

Öz

More than one method has been developed to increase flexibility. One of these methods is foam rolling applications. Although they have different forms, vibrating foam rollers have different frequencies. This study aims to determine the effects of foam roller application applied at different frequency levels on flexibility. Twenty male amputee athletes participating in the study were randomly divided into two groups. Then the flexibility levels of the players were evaluated. After the measurement, vibrating foam rollers with a frequency of 32 Hz and 62 Hz were applied to the 1st and 2nd groups, respectively. Finally, the flexibility measurement was repeated. For the data analysis, 2x2 repeated measures ANOVA was used. As a result of the analyses performed to determine the changes in the range of motion, the main time effect was found to be significant (p <0.001), while the time and group interaction were not significant (p= 0.75). Post Hoc analysis showed that the foam roller application with both frequencies was significant (p <0.001) in increasing range of motion. However, frequency differences do not affect flexibility levels (p= 0.52). The result of this study indicates that the application of vibration foam rolling at different frequency levels is an effective method to increase range of motion. It is also seen that increasing the frequency level does not affect flexibility.

AMPUTE FUTBOLCULARDA FARKLI FREKANS SEVİYELERİNDE UYGULANAN FOAM ROLLER’IN NORMAL EKLEM HAREKETİ ÜZERİNE AKUT ETKİSİ

Öz

Esnekliğin artırılması için birden fazla yöntem geliştirilmiştir. Bu yöntemlerden biri de foam rolling uygulamalarıdır. Değişik formları olmakla beraber titreşimli foam rollerin farklı frekansları bulunmaktadır. Bu çalışmanın amacı farklı frekans seviyelerinde uygulanan foam roller uygulamasının esnekliğe etkilerinin belirlenmesidir. Çalışmaya katılan 20 erkek ampute sporcu randomize şekilde 2 gruba ayrılmıştır. Daha sonra oyuncuların esneklik seviyeleri değerlendirilmiştir. Ölçüm sonrası 1. gruba 32 Hz, 2. gruba ise 62 Hz frekansa sahip titreşimli foam roller uygulanmıştır. Son olarak esneklik ölçümü tekrar edilmiştir. Verilerin analizi için 2x2 tekrarlı ölçümlerde ANOVA testi kullanılmıştır. Normal eklem hareketi değişimlerinin belirlenmesi için yapılan analizler neticesinde ana zaman efekti anlamlı bulunurken (p<0.001), zaman ve grup etkileşimi anlamlı bulunmamıştır. Post Hoc analizlerinde her iki frekansa sahip uygulamanın da normal eklem hareketini arttırmada anlamlı (p<0.001) olduğu görülmüştür. Ancak frekans farklılıkları esneklik seviyelerine etki etmemektedir (p=0.524). Bu çalışma sonucu farklı frekans seviyelerinde uygulanan foam rolling uygulamasının normal eklem hareketini arttırmada etkin bir yöntem olduğuna işaret etmektedir. Ayrıca frekans artırımının esneklik üzerine bir etki oluşturmadığı da görülmektedir.
