Genç Voleybolcularda Sekiz Haftalık Kombine Kuvvet, Sprint, Pliometrik ve Yön Değiştirme Antrenmanı Öncesi ve Sonrası Sıçrama, Sürat ve Çeviklik Performansındaki Değişimler

Öz

Bu çalışmanın amacı, 8 haftalık kombine kuvvet ve sprint antrenman programının genç voleybolcularda vücut kompozisyonu, sıçrama, sürat ve çeviklik üzerindeki etkilerini incelemektir. Bölgesel liglerde mücadele eden otuz sporcu (U14: n = 15, U16: n = 15; 15 erkek, 15 kadın), kulüp antrenmanlarına ek olarak haftada iki antrenman seansı uyguladı. Çalışmada tek gruplu ön test–son test tasarımı kullanıldı. Vücut yağ yüzdesi, yağsız kütle, countermovement jump (CMJ), tek bacak sıçrama, 10 m ve 30 m sprint ve T-Test değerlendirildi. Veriler eşleştirilmiş t-testleri ile analiz edildi ve etki büyüklükleri Cohen’s d kullanılarak hesaplandı. Sekiz hafta sonunda vücut yağ yüzdesi %1.2–1.5 azaldı, yağsız kütle 1.2–1.3 kg arttı, CMJ yüksekliği 2.7–3.5 cm arttı, 10 m sprint süreleri 0.03–0.04 sn azaldı ve T-Test süreleri 0.15–0.35 sn azaldı (p < 0.05). Sonuçlar, kombine kuvvet ve sprint antrenmanının özellikle genç voleybolcularda ivmelenme, çeviklik ve sıçrama performansını geliştirme potansiyeline sahip olduğunu göstermektedir.

Changes in Jump, Speed, and Agility Performance Before and After Eight Weeks of Combined Strength, Sprint, Plyometric, and Change-of-Direction Training in Youth Volleyball Players

Öz

The aim of this study is to examine the effects of an 8-week combined strength and sprint training program on body composition, jump, speed, and agility in youth volleyball players. Thirty athletes competing in regional leagues (U14: n = 15, U16: n = 15; 15 males, 15 females) performed two training sessions per week in addition to club practices. The study employed a single-group pre–post design. Body fat percentage, lean mass, countermovement jump (CMJ), single-leg jump, 10 m and 30 m sprint, and the T-Test were evaluated. Data were analyzed with paired t-tests, and effect sizes were calculated using Cohen’s d. After eight weeks, body fat percentage decreased by 1.2–1.5%, lean mass increased by 1.2–1.3 kg, CMJ height increased by 2.7–3.5 cm, 10 m sprint times decreased by 0.03–0.04 s, and T-Test times decreased by 0.15–0.35 s (p < 0.05). The results indicate that combined strength and sprint training has the potential to improve acceleration, agility, and jump performance, particularly in youth volleyball players.
