TENİSÇİLERDE PLİOMETRİK ANTRENMANLARIN SERVİS ATIŞINDA TOPUN HIZINA VE İSABETİ YÜZDELERİNE ETKİSİNİN İNCELENMESİ

Öz

ÖZET Bu çalışmada, tenisçilerde pliometrik antrenmanların servis vuruş süratleri ve vurulan hedefe isabet yüzdelerine etkisi araştırılmıştır. Çalışmaya, yaşları 20-25 arasında 40 erkek tenisçi gönüllü olarak katıldı. Katılımcılar yaşlarına göre karşılıklı olarak dengelendi ve yansız atama yolu ile deney n=20 ve kontrol n=20 grubuna ayrıldı. Deney grubu üyeleri sekiz haftalık klasik tenis antrenmanlarına ilave olarak pliometrik antrenman programına katılırken haftada 3 gün, günde 2 set , kontrol grubu bu süreçte sadece klasik tenis antrenmanına devam etti. Bağımlı değişkenlere ilişkin ölçümler çalışmanın başlangıcında, 4. haftanın ve 8. haftanın sonunda yapıldı. Antrenman programının bağımlı değişkenler üzerindeki etkilerini değerlendirmek için Mixed between-within subjects ANOVA kullanıldı. Ortalama pik tork skorlarındaki anlamlı değişimlerin alt vücut için özellikle 600/sn ve 1200/sn deki direnç hızlarında sağ ekstansiyon / sağ fleksiyon , üst vücut için 600/sn deki direnç hızında dış rotasyon deney grubundan kaynaklandığı görülmüştür p≤.05 . Serviste sağ ve soldan kullanılan vuruşlardaki maksimum hız gelişimleri deney grubunda anlamlı olarak daha fazla olmuş, isabet skorlarındaki gelişim tüm servis atışlarında deney grubunda ortaya çıkmıştır p≤.05 . Sonuç olarak, klasik tenis antrenmanına ilave olarak uygulanan pliometrik egzersizlerin tenisçilerin omuz ve bacak kuvveti üzerinde olumlu etkiler yaptığı, atış ve vuruş hızları ile birlikte isabet oranlarınıda geliştirdiği görülmüştür.

EVALUATION OF THE EFFECT OF PLYOMETRIC EXERCISES ON THE SPEED OF THE BALL AND THE HITTING PERCENTAGE DURING A SERVICE

Öz

In this study, the effect of the plyometric exercises on the speed and the hittingpercentages of the services in tennis players was investigated. 40 male volunteer tennisplayers aged between 20-25 were included the study. The participants were balanced anddivided into the study n=20 and the control n=20 groups via unbiased allocation. Theparticipants in the study group attended the plyometric exercise programme in addition to theclassical eight-week tennis exercise 3 days in a week, 2 sets in each day while theparticipants in the control group continued only the classical tennis exercise. Themeasurements of the dependent variables were done at the beginning of the study, at theend of the fourth and the eighth weeks. The mixed between-within subjects ANOVA was usedto evaluate the effects of the exercise programme on the dependent variables. It was seenthat the significant differences in the mean peak torque scores was originated from the studygroup and it was particularly in the resistance velocity of 600/second and 1200/second rightextension/right flexion for the lower body and in the resistance velocity of 600/second external rotation for the upper body p
