Abstract (2. Language): 
The purpose of the study is to analyse the fitness and the biomechanical factors which determine the velocity of the ball during serve in tennis (VBTS). The subjects of the study were fifteen male tournament level tennis player between the ages of sixteen and twenty five (18,8 2,70 age/year). The physical fitness measurement of the study were; length, body weight, skinfold, diameter, circumference and length of the body, body composition, isometric handgrip strength, vertical jump, upper extremity range of motion (ROM) and isokinetic strength. The angular velocity of racket head, racket handhold, middle finger, wrist, elbow, shoulder and hip joints on three axis during serve shoot were used for the biomechanical measurement. The relationship between VBTS with physical fitness and biomechanical factors were measured with Pearson Correlation. The analysis showed that there was significant positive relation between VBTS and length, negative relation with mesomorphy; positive relation between ROM of shoulder dominant internal and external rotation, trunk hyper-extension, left lateral flexion and right rotation, negative relation in dominant wrist flexion, positive relation between isokinetic strength characteristics such as shoulder and elbow extension, shoulder internal and external rotation, wrist flexion, handgrip isometric strength, also in biomechanical measures, positive relation between in Y axis elbow, wrist, finger and head of the racket. As a result, fitness and biomechanical parameters that are intensively used in tennis determine VBTS. We think trainers may speed up VBTS by improved parameters and accelerated training programmes.

Abstract (Original Language): 
Bu çalışma teniste servis atışında top hızı (SATH) ile fiziksel uygunluk ve biyomekaniksel faktörler arasındaki ilişkiyi incelemek amacıyla yapılmıştır. Yaşları on altı ile yirmi beş (18,8 2,70 yaş/yıl) arasında değişen toplam on beş turnuva seviyesi erkek tenis oyuncusu araştırmaya alınmıştır. Çalışmada fiziksel uygunluk ölçümleri olarak boy, beden ağırlığı, deri kıvrım kalınlığı, çap, çevre, uzunluk, beden kompozisyonu, el izometrik kuvvet, dikey sıçrama, üst ekstremite eklem hareket genişlikleri (EHG) ve izokinetik kuvvet parametreleri değerlendirmeye alınırken, biyomekaniksel ölçümlerde de servis atışı esnasında raket başı, raket sapı, orta parmak, el bileği, dirsek, omuz ve kalça eklemlerinin üç eksen üzerindeki açısal hızları değerlendirmeye alınmıştır. SATH ile fiziksel uygunluk ve biyomekaniksel faktörler arasındaki ilişki Pearson Korelasyon analizi ile hesaplanmıştır. Yapılan bu çalışmada SATH ile boy uzunluğu pozitif, mezomorfi negatif yönde; EHG’ den omuz iç ve dış rotasyon, gövde hiperekstansiyon, sol lateral fleksiyon, sağ rotasyon pozitif yönde, dominant el bileği fleksiyon negatif yönde; izokinetik kuvvet özelliklerden omuz ve dirsek ekstansiyon, omuz iç ve dış rotasyon, el bileği fleksiyon, dominant el izometrik kuvvet pozitif yönde; biyomekanik ölçümlerden Y eksen üzerindeki dirsek, el bileği, parmak, raket başı arasında pozitif yönde ilişki bulunmuştur. Sonuç olarak; teniste yoğun olarak kullanılan fiziksel uygunluk ve biyomekaniksel parametrelerin servis atış hızını belirlediği gözlenmiştir. Antrenörler bu parametreleri geliştirebilecekleri ve hızlandırabilecekleri antrenman programları ile servis atışında top hızını arttırabilecekleri düşüncesindeyiz.
