Abstract

Objectives: The aim of this study was to investigate the joint angle differences in successful and unsuccessful tennis serves of junior tennis players. Patients and methods: Nine healthy junior tennis players (5 girls, 4 boys; mean age 11.8±0.8 years; height 153.6±7.2 cm; body mass index 42.3±4.1 kg; playing experience 6.2±1.5 years) volunteered to participate in this study. They were asked to perform tennis serves as fast as they can as if they were in an actual game. Successful and unsuccessful serves were recorded using two high speed cameras and then analyzed using Pictran software. Angle changes in pre-impact, impact and postimpact phases were compared. Results: The results of paired sample t-tests revealed nosignificant differences between successful and unsuccessful tennis serves in all three phases. Conclusion: This study failed to show differences between successful and unsuccessful tennis serves in pre-impact, impact and post-impact phases. However, future research with more detailed analyses would be needed to reveal the possible changes in the joints while serving.

Özet

Amaç: Bu çalışmada genç tenisçilerin başarılı ve başarısız tenis servisi atışları arasındaki eklem açı farkları incelendi. Hastalar ve yöntemler: Dokuz sağlıklı tenisçi (5 kız, 4 erkek; ort. yaş 11.8±0.8 yıl; boy 153.6±7.2 cm; vücut kütle indeksi 42.3±4.1 kg; oyunculuk deneyimleri 6.2±1.5 yıl) çalışmaya katılmak için gönüllü oldu ve gerçek tenis maçında olduklarını varsayarak atabilecekleri kadar hızlı servis atışı yaptı. Başarılı ve başarısız servis atışları saniyede 60 resim kaydedebilen iki adet kamera ile kaydedildi ve daha sonra Pictran yazılımı ile analiz edildi. Topa vuruş öncesi, vuruş anı ve vuruş sonrasındaki eklem açıları karşılaştırıldı. Bulgular: Bağımlı değişkenler t-testi ile analizi yapılan bu üç vuruş safhasında başarılı ve başarısız servisler arasında anlamlı bir fark görülmedi. Sonuç: Çalışmanın bulguları servis atışının vuruş öncesi, vuruş anı ve vuruş sonrası safhalarında başarılı ve başarısız denemeler arasında bir fark olmadığını ortaya koydu. Servis atışı sırasında olası eklemsel değişikliklerin ortaya çıkartılması amacıyla daha detaylı incelemelerin yapılması gerekmektedir.
