Objective: The purpose of this study was to investigate the relationship between body composition, agility and vertical jump performance in young female volleyball players. Material and Methods: For this purpose, 23 healthy young female volleyball players (Age: 14.79±0.58 years, height: 169.70±5.62 cm, body weight: 61.44±7.92 kg.) voluntarily participated in this study. The volleyball team was assessed for total body and regional estimates of body composition by using dual-energy X-ray absorptiometry. Vertical jump performance was analyzed by using the Squat Jump (SJ) and Counter Movement Jump (CMJ) tests and agility performance was measured using the Tagility test. The normality of the data was tested with the Shapiro-Wilk test. The relationship between body composition, agility and vertical jump performance was analyzed with Pearson correlation coefficient. Significance level was ≤0.05. Results: According to the statistical analyses, there was a significant negative correlation between SJ and CMJ percentage of body fat (BF%) leg fat (LF%) arm fat (AF%), trunk fat (TF%) and fat mass (kg) (p˂0.05). There was also a significant correlation between agility test percentage of BF, LF and TF. No significant correlation was found among agility, SJ and CMJ with total/regional body composition. Conclusion: The results indicated that increased total/regional BF might be a detriment to the SJ, CMJ and agility performance in young female volleyball players. It is recommended that coaches should not allow female volleyball players to increase their BF so that physical performance loss can be avoided.

Amaç: Bu çalışmanın amacı, genç kadın voleybol oyuncularında vücut kompozisyonu, çeviklik ve dikey sıçrama performansı arasındaki ilişkiyi araştırmaktır. Gereç ve Yöntemler: Bu amaçla, 23 kadın voleybol oyuncusu (yaş: 14,79±0,58 yıl, boy: 169,70±5,62 cm, kilo: 61,44±7,92 kg.) araştırmaya gönüllü olarak katılmıştır. Dual enerji X-ışını absorptiometrisi yöntemi ile tüm ve bölgesel vücut kompozisyonu belirlenmiştir. Dikey sıçrama performans testleri squat sıçrama (SS) ve aktif sıçrama (AS) ve çeviklik performansı T-çeviklik testi kullanılarak ölçülmüştür. Verilerin normallik sınaması, Shapiro-Wilk testi ile test edilmiştir. Tüm vücut ve bölgesel vücut kompozisyonu, çeviklik testi yeteneği ve sıçrama parametreleri arasında ilişki olup olmadığı Pearson korelasyon analizi ile belirlenmiştir. Anlamlılık düzeyi ≤0,05 alınmıştır. Bulgular: İstatiksel analizler sonucunda kadın voleybol oyuncularında SS ve AS testi ile vücut, bacak, kol ve gövde yağ yüzdesi ve kütlesi (kg) arasında negatif ilişki bulunmuştur (p˂0,05). Aynı zamanda çeviklik test ile vücut, bacak ve gövde yağ yüzdesi arasında ilişki bulunmuştur. Çeviklik, SS ve AS ile diğer toplam/bölgesel vücut kompozisyonu arasında önemli bir ilişki görülmemiştir. Sonuç: Bu araştırma sonuçlarına göre artan tüm/bölgesel vücut yağının genç kadın voleybol oyuncularında SS, AS ve çeviklik performansını olumsuz etkileyebileceğini göstermiştir. Antrenörlerin yıllık periyot planlamasında fiziksel performans kaybını önlemek için bayan voleybolcuların vücut yağlanma artışına izin vermemesi önerilir.
