Objective: To investigate the effects of lower extremity plyometric training programme on jumping height, aerobic power, anaerobic power, sprint performance and balance in young female volleyball players. Materials and methods: 35 female adolescent volleyball players were included in the study. The participants were separated in two study groups: a study group (lower extremity plyometric training combined with jump rope exercises; n=18) and a control group (standard volleyball training; n=17). All subjects were evaluated before and after 12-week training. A vertical jump and reach test (VRJT) was performed to assess jump height. Anaerobic capacity was calculated using a formula by VRJT. 20 meters shuttle run test, Y-balance test (YBT) and 20 meters sprint test were performed to assess aerobic capacity, dynamic balance and sprint performance, respectively. Statistical comparison was performed using an analysis of variance test. Results: Comparisons showed that aerobic capacity was improved in two groups (p<0.05). Jumping height, anaerobic power, sprint time and YBT distance to anterior direction was improved in study group (p<0.05), whereas no improvement was seen in control group (p>0.05). YBT distances to posteromedial and posterolateral directions were more improved in study group than control group (p<0.05). Conclusion: Results of this study showed benefits of addition of plyometric exercises to standard training in young female volleyball players. This study will be a basis for developing training programmes.

Amaç: Genç bayan voleybol oyuncularında alt ekstremite pilometrik eğitimin sıçrama yüksekliği, aerobik güç, anaerobik güç, sprint performansı ve denge üzerine etkisini araştırmak. Gereç ve Yöntemler: Bu çalışmaya 35 bayan adölesan voleybol oyuncusu dahil edildi. Katılımcılar iki gruba ayrıldı: çalışma grubu (alt ekstremite pilometrik eğitimi+standart voleybol eğitimi; n=18) ve kontrol grubu (standart voleybol eğitimi; n=17). Bütün katılımcılar 12 haftalık eğitimin öncesinde ve sonrasında değerlendirildi. Sıçrama yüksekliğinin değerlendirilmesi için dikey sıçrama testi yapıldı. Anaerobik kapasite dikey sıçrama testi sonucuna göre formül kullanılarak tahmin edildi. Aerobik kapasite, dinamik denge ve sprint performansını değerlendirmek için sırasıyla 20 metre mekik koşu testi, Y-denge testi (YDT) ve 20 metre sprint testi yapıldı. İstatistiksel karşılaştırma varyans analizi testi kullanılarak yapıldı. Bulgular: Aerobik kapasite iki grupta da gelişti (p<0.05). Sıçrama yüksekliği, anaerobik güç, sprint süresi ve anterior yönde YDT mesafesi kontrol grubunda gelişmezken (p>0.05), çalışma grubunda gelişti (p<0.05). Posteromedial ve posterolateral yöndeki YDG mesafeleri çalışma grubunda kontrol grubundan daha çok gelişti (p<0.05). Sonuç: Bu çalışmanın sonuçları genç bayan voleybol oyuncularında pilometrik eğitimin standart eğitim programına eklenmesinin yararlarını göstermiştir. Bu çalışma antreman programlarının geliştirilmesinde temel oluşturacaktır.
