Tenis Antrenmanında Pointer Raket Kullanımının, Oyun Seviyesi, Koordinasyon ve Yer Vuruşları Mekaniğine Etkisinin İncelenmesi

Öz

Bu araştırmanın amacı, tenis antrenmanlarında eğitim ve gelişim materyali olarak kullanılan tahtadan yapılmış dar bir vuruş alanına sahip, popüler bir raket olan ve ismi dilimizde kaşık raket olarak adlandırılan pointer raket ile antrenman yapmanın, normal raket ile yapılan antrenmanlara oranla, el-göz koordinasyonu, yer vuruşları oyun seviyesi, vuruş hızı ve ağırlığı, döngü seviyesi ve sweet spot düzeyi gibi parametrelerin gelişimine olan etkisinin incelenmesidir. Çalışma 6 hafta olarak planlanmış ve başlangıç öncesi ön test ve 6 hafta sonunda son test ölçümleri alınmış ve istatistiki olarak işlenmiştir. Çalışmaya yaş ortalamaları 21,47 yıl, boy ortalamaları 172,07 cm ve vücut ağırlığı ortalamaları 68,13 kg olan 15 erkek 15 kadın toplam 30 üniversite öğrencisi katılmıştır. Antrenmanlar 6 hafta boyunca haftada 3 gün sıklığında ve her antrenman 90 dakika olacak şekilde planlanmıştır. Deney grubu ve kontrol grubu aynı antrenman içeriğine maruz kalmışlardır. Fakat deney grubu, antrenmanların 30 dakikalık bölümünde pointer raket kullanırken kontrol grubu ise aynı süre için normal raket kullanmıştır. Çalışmada gerçekleştirilen ön test ve son testlerden elde edilen verilerin karşılaştırılması için, grup içi tekrarlayan ölçümlerde bağımlı örneklem t testi, gruplar arası farkın belirlenmesinde ise bağımsız örneklem t testi kullanılmıştır. Her iki grupta da grup içi tekrarlayan ölçüm sonuçları arasında oyun seviyesi, vuruş hızı ve vuruş ağırlığı başlıklarında istatistiksel olarak anlamlı fark tespit edilmiştir. Gruplar arası karşılaştırma sonuçlarında ise; oyun seviyesi, vuruş hızı ve vuruş ağırlığı başlıklarında ön testlerde anlamlı fark çıkmazken son testlerde deney grubu lehine anlamlı farklılıklar bulunmuştur. Ayrıca, sadece deney grubunun ön test ve son test sonuçlarına göre el-göz koordinasyon skoru ve sweet spot düzeyinde anlamlı artış olmuştur. Sonuç olarak; ITN yer vuruş skorları orta seviyenin altında olan bireylerde, pointer raket kullanılarak yapılan antrenmanların el-göz koordinasyonu, yer vuruşları oyun seviyesi, vuruş hızı, vuruş ağırlığı ve sweet spot düzeyini anlamlı seviyede geliştirdiği söylenebilir.

Investigation of the Effect of Pointer Racket Use in Tennis Training on Tennis Level, Coordination and Ground Stroke Mechanics

Öz

The aim of this study was to examine the effects of training with a pointer racket—a wooden racket with a narrow hitting surface, commonly known as a “spoon racket”—on various tennis performance parameters. Specifically, the research evaluated its influence on hand-eye coordination, groundstroke level of play, stroke velocity, stroke heaviness, spin level, cycle level, and sweet spot performance, compared to training with a normal racket. The study lasted six weeks and included pre- and post-test measurements. A total of 30 university students (15 male, 15 female; mean age = 21.47 years; mean height = 172.07 cm; mean weight = 68.13 kg) participated. Training sessions were conducted three days per week, each lasting 90 minutes. Both the experimental and control groups performed the same training program; however, the experimental group used the pointer racket for 30 minutes of each session, while the control group used a normal racket. To analyze the data, dependent sample t-tests were applied for within-group comparisons, and independent sample t-tests were used to determine differences between groups. Significant improvements were observed in both groups for game level, stroke velocity, and stroke heaviness in repeated measures. Between-group comparisons showed no significant differences in pre-test results; however, post-test results revealed significant advantages in favor of the experimental group. Additionally, only the experimental group showed significant increases in hand-eye coordination and sweet spot performance. In conclusion, training with a pointer racket significantly enhances hand-eye coordination, groundstroke level, stroke velocity, stroke heaviness, and sweet spot performance among individuals with ITN groundstroke scores below the medium level.
