The purpose of this study was to investigate the potential correlation between forehand and backhand performance, as well as sweet-spot scores, among female recreational tennis players. Eighteen recreational female tennis players between the ages of 21 and 24 voluntarily participated in this study. The ZEPP-2 Tennis Sensor was used to assess Sweet-Spot performances, and the forehand and backhand strike performance was evaluated using the " Groundstroke Depth " and " Groundstroke Accuracy" sections of the ITN test administered by the International Tennis Federation. The SPPS 25.0 package programme was used in the analysis of data. As a result, no statistically significant relationship was found between forehand stroke and sweet spot score variables in ITN 1 (r=0.073; p>0.05) and ITN 2 (r=0.230; p>0.05) sections of the test. Similarly, there was also no correlation between backhand stroke and sweet spot variables in ITN 1 (r=0.265; p>0.05) and ITN 2 (r=0.408; p>0.05). According to the results of the study, although it has been suggested that the sweet spot score in tennis may have an impact on strikes, the findings indicate that the sweet spot score alone is not a sufficient parameter for accuracy in forehand and backhand strikes.

Rekreatif Seviye Kadın Tenis Oyuncularında Forehand ve Backhand Vuruş Performansları ile Sweet-Spot Skorları Arasındaki İlişkinin Belirlenmesi

Öz

Bu araştırma rekreatif seviye kadın tenis oyuncularında forehand ve backhand vuruş performansları ile sweet-spot skorları arasındaki ilişkinin belirlenmesi amacıyla yapılmıştır. Çalışmaya yaşları 21-24 arasında değişen toplam 18 kadın gönüllü olarak katılmıştır. Sweet-Spot performanslarının belirlenmesinde ZEPP-2 Tenis Sensörü, Forehand ve Backhand Vuruş performansının belirlenmesinde ise Uluslararası Tenis Federasyonu tarafından uygulanan ITN (International Tennis Number) testindeki “Yer Vuruşu Derinliği” ve “Yer Vuruş Hassasiyeti” bölümlerinde yer alan test prosedürü kullanılmıştır. Verilerin analizinde SPSS 25.0 paket programın kullanılmıştır. Test bölümlerinden; ITN 1 (r=0.073; p>0.05) ve ITN 2'de (r=0.230; p>0.05) forehand vuruş ve sweet spot skoru değişkenleri arasında istatistiksel olarak anlamlı bir ilişki bulunmamıştır. Benzer şekilde, ITN 1 (r=0.265; p>0.05) ve ITN 2'de (r=0.408; p>0.05) backhand vuruş ile sweet spot değişkenleri arasında da anlamlı bir ilişki bulunmamıştır. Sonuç olarak, teniste sweet-spot skorunun vuruşlar üzerinde etkili olabileceğinin düşünülmesine rağmen çalışmanın bulguları sweet spot skorunun forehand ve backhand vuruşlarında isabet için tek başına yeterli bir parametre olmadığı sonucunu göstermektedir.
