The impact of periodized core training program on accurate service velocity of male tennis players aged 11-13 11-13 yaş arası erkek tenisçilerde periyotlanmış core antrenman programının isabetli servis hızına etkisi

The purpose of this study is to examine the effect of periodized core training program on the serve velocity in male tennis players aged 11-13 years. 24 male nationally ranged (age 11.9±1.63, height 154.4±11.32, weight 43±8.76) participated to the study from a professional tennis club. Pre-post-training - control group design was applied and subjects were randomly assigned to Control Group and Training Group. Training Group participated to the core training program consisted of isometric and isotonic core stabilization exercises on stable and nonstable surfaces, three days in a week for 8 weeks in addition to tennis training sessions. Accurate service velocity, was assessed initially and at the end of the 8-week core program for both control and training groups. There was a significant improvement (6.6 %) in the serve velocity for the training group after the experiment, whereas there were no differences in the control group. Core stabilization training improved service velocity for young tennis players. It is recommended tennis coaches to apply periodized core stabilization exercises to young athletes and plan training programs in this way.

Ozet Bu calismanin amaci 11-13 yas arasi erkek teniscilerde periyodlanmis core antrenman programinin isabetli servis hizina etkisini incelemektir. Calismaya profesyonel bir tenis kulubunden ulusal musabik 24 erkek tenisci (yas 11.9±1.63, boy 154.4±11.32, agirlik 43±8.76) katilmistir. Arastirmada on-test son-test kontrol gruplu model uygulanmis, denekler iki gruba rastgele atanmistir. 12 sporcu Kontrol Grubunu, 12 sporcu ise Deney Grubunu olusturmustur. Deney Grubuna haftanin uc gunu yarim saatlik 8 hafta boyunca toplamda 24 antrenman birimi stabil ve stabil olmayan yuzeylerde izometrik ve izotonik core stabilizasyon egzersizlerinden olusan program, tenis antrenmanlarina ek olarak uygulanmistir. Program oncesi ve sonrasinda her katilimci maksimal hizda 10 servis kullanarak en hizli ve gecerli atislari kaydedilmistir. Core antrenman uygulamasi sonrasi Kontrol Grubunun servis atis hizi degismezken, Deney Grubu servis atis hizini ortalama 120.93 km/s hizdan 128.6 km/s hiza (% 6.6) cikarmistir. Core antrenman uygulamalarinin genc teniscilerde isabetli servis hizini olumlu etkiledigi tespit edilmistir. Tenis antrenorlerinin yuksek siddet icermeyen, core antrenmanlarini ve stabilizasyon uygulamalarini genc sporcularda uygulamasinin yararli olacagi dusunulmekte ve antrenman programlarini buna gore planlamalari tavsiye edilmektedir.
