Abstract

Bu çalışmanın amacı, bölgesel lig kadın voleybolcularda antrenman öncesinde yapılan dinamik germe (DG) ve dinamik germeye ek olarak yapılan foam roller (FR) egzersizlerinin squat jump (SJ) ve countermovement jump (CMJ) değerlerine akut etkisinin incelenmesiydi. Çalışma grubu 15 kişilik, (yaş ortalaması 21,5±3,5 yıl, boy uzunluğu ortalaması 170,5±6,7cm, vücut ağırlığı ortalaması 58,25±6,57 kg) tek gruptan oluşmaktaydı. Çalışmanın ilk günü öğrenme etkisini ortadan kaldırmak amacıyla sporculara Squat Jump ve Countermovement Jump egzersizlerinde deneme alıştırmaları yaptırıldı. Çalışmanın ikinci günü tüm sporculara 10 dakikalık düşük tempo ısınma koşusunun ardından belirlenen dinamik germe egzersizleri uygulatıldı. Sonrasında My Jump 2 aplikasyonu ile Squat Jump ve Countermovement Jump egzersizlerinde sporcuların dikey sıçrama verileri toplandı. Sporculara üçüncü günü ölçüme başlanmadan önce 48 saatlik bir dinlenme süreci verildi. Üçüncü gün ölçümlerinde ise sporcular aynı ısınma protokolü uygulattırıldı ve ek olarak Foam Roller uygulaması yaptırıldı. Ardından sporcuların tekrar Squat Jump ve Countermovement Jump ölçümleri alındı. Uygulama öncesi ve sonrası grup içi değişimler Wilcoxon Test ile değerlendirildi. Ön test ve son test bulgularının grup içi istatistiksel analizinde; FR uygulamasının, SJ ve CMJ egzersizlerinde anlamlı farka neden olduğu tespit edildi (p<0,05). Kadın voleybolcularda FR uygulamasının, SJ ve CMJ sonuçlarında artış sağlayarak olumlu yönde etkisi olduğu gözlemlendi. Antrenman ve müsabaka öncesi ısınma periyotlarında gerçekleştirilen germe egzersizlerine ek olarak FR uygulamasına da yer verilmesinin yararlı olabileceği düşünülmektedir.

Investigation of the Acute Effect of Dynamic Stretching and Foam Roller Exercise Performed Before Training on Countermovement Jump and Squat Jump Values in Regional League Women Volleyball Players

Abstract

The aim of this study was to examine the acute effects of dynamic stretching (DG) and foam roller (FR) exercises performed in addition to dynamic stretching before training on squat jump (SJ) and countermovement jump (CMJ) values in regional league female volleyball players. The study group consisted of a single group of 15 individuals (mean age 21.5±3.5 years, average height 170.5±6.7 cm, average body weight 58.25±6.57 kg). In order to eliminate the learning effect on the first day of the study, the athletes were given trial exercises in Squat Jump and Countermovement Jump exercises. On the second day of the study, dynamic stretching exercises were applied to all athletes after a 10-minute low-tempo warm-up run. Afterwards, vertical jump data of the athletes were collected in the Squat Jump and Countermovement Jump exercises with the My Jump 2 application. A rest period of 48 hours was given to the athletes before starting the measurement on the third day. In the third day measurements, the same warm-up protocol was applied to the athletes and an additional Foam Roller application was made. Then, the athletes' Squat Jump and Countermovement Jump measurements were taken again. Intra-group changes before and after the application were evaluated with the Wilcoxon Test. In the statistical analysis of the pre-test and post-test findings; It was determined that FR application caused a significant difference in SJ and CMJ exercises (p<0.05). It was observed that FR application in female volleyball players had a positive effect by increasing the results of SJ and CMJ. It is thought that it may be beneficial to include FR practice in addition to the stretching exercises performed during the warm-up periods before training and competition.
