The Relationship Between Lower Extremity Strength, Anaerobic Power, and Change of Direction Speed in Female Basketball Players

Abstract

The purpose of this study is to examine the relationship between lower extremity strength, anaerobic power, and change-of-direction speed in female basketball players. Twenty-nine well-trained young female basketball players aged 14-20 (mean ± SD; age: 15.48 ± 1.81 years; body weight: 65.70 ± 12.48 kg; and height: 175.90 ± 7.50 cm) voluntarily participated in the study. This study was conducted during a period when there were no competitive games (off-season). The study was conducted in 3 different sessions, each 48 hours apart. Participants underwent measurements of body composition, isokinetic knee extension and flexion strength, anaerobic power (Wingate Test, WAnT), and change of direction speed (CoDs, T-test). Normality analysis (Shapiro-Wilk) was performed for data analysis. The relationships between lower extremity isokinetic strength, anaerobic power, and change of direction speed were analyzed using Pearson's correlation test. A significant relationship was found between right knee extension, right knee flexion, left knee extension, and left knee flexion isokinetic values and absolute peak power (p < 0.05). A significant relationship was observed between absolute peak power and CoDs (p < 0.05). In conclusion, the isokinetic strength of female basketball players provides a prediction of their anaerobic performance. These findings and the results of this study are thought to make important contributions to coaches in improving and monitoring athlete performance.

Kadın Basketbolcularda Alt Ekstremite Kuvveti, Anaerobik Güç ve Yön Değiştirme Hızı Arasındaki İlişki

Abstract

Bu çalışmanın amacı, kadın basketbolcularda alt ekstremite kuvveti, anaerobik güç ve yön değiştirme hızı arasındaki ilişkinin incelenmesidir. Çalışmaya, 14-20 yaş arasında iyi antrenmanlı yirmi dokuz genç kadın basketbolcu (ortalama ± SD; yaş: 15.48 ± 1.81 yıl; vücut ağırlığı: 65.70 ± 12.48 kg; ve boy: 175.90 ± 7.50 cm) gönüllü olarak katılmıştır. Bu çalışma rekabetçi maçların olmadığı bir zamanda (devre arası dönemde) yapılmıştır. Çalışma her biri arasında 48 saat olan 3 farklı seansta gerçekleştirilmiştir. Çalışmada katılımcılara vücut kompozisyon, izokinetik diz ekstansiyon ve fleksiyon kuvveti, anaerobik güç (Wingate Testi, WAnT) ve yön değiştirme hızı (T testi) ölçümleri uygulandı. Verilerin analizinde normallik analizi (Shapiro-wilk) yapıldı. Alt ekstremti izokinetik kuvveti, anaerobik güç ve yön değiştirme hızı arasındaki ilişkiler Pearson korelasyon testi ile analiz edilmiştir. Sağ diz ekstansiyon, sağ diz fleksiyon, sol diz ekstansiyon ve sol diz fleksiyon izokinetik değerleri ile mutlak zirve güç arasında anlamlı ilişki tespit edilmiştir (p < 0.05). Mutlak zirve güç ile yön değiştirme hızı arasında anlamlı ilişki olduğu görülmüştür (p < 0.05). Sonuç olarak, kadın basketbolcuların izokinetik kuvvetlerinin anaerobik performansları ile ilgili bir öngörü sunmaktadır. Bu bulguların ve çalışma sonucunun, antrenörlere sporcu performansının artırılması ve takip edilmesinde önemli katkılar sunabileceği düşünülmektedir.
