Evaluation of the Relationship Between Trunk Muscle Endurance, Spinal Mobility and Lower Extremity Stabilization in Volleyball Players (Pilot Study)

Öz

This study aimed to investigate the physical performance, balance characteristics, and interrelationships between core endurance and dynamic balance parameters in female volleyball players. Fifteen athletes participated in this cross-sectional study. Demographic and training characteristics were recorded, and physical performance was assessed using abdominal endurance, Sorenson, lateral bridge, and lateral lumbar flexion tests. Dynamic balance was evaluated with the Y Balance Test, and postural stability was assessed using the Tetrax posturography system. Descriptive data were presented as median and interquartile range, while relationships between variables were analyzed using Spearman’s correlation test. The participants had a median age of 20 years and a median volleyball experience of 9 years. Significant positive correlations were found between abdominal endurance and the Sorenson test (r = 0.745, p = 0.001) and lateral lumbar flexion test (r = 0.722, p = 0.002). The Sorenson test was strongly associated with lateral lumbar flexion (r = 0.764, p = 0.001) and moderately correlated with the lateral bridge test (r = 0.558, p = 0.031). Additionally, abdominal endurance showed a moderate correlation with right posterolateral Y Balance performance (r = 0.531, p = 0.042). No significant associations were observed between balance performance in the left posterolateral direction and core endurance measures (p > 0.05). These findings indicate that core endurance, particularly trunk extensor and abdominal strength, is closely related to dynamic balance performance in female volleyball players.

Voleybolcularda Gövde Kas Enduransı, Spinal Mobilite ile Alt Ekstremite Stabilizasyon Arasındaki İlişkinin Değerlendirilmesi (Pilot Çalışma)

Öz

Bu çalışmanın amacı, kadın voleybolcularda fiziksel performans, denge özellikleri ve core enduransı ile dinamik denge parametreleri arasındaki ilişkilerin incelenmesidir. Bu kesitsel çalışmaya toplam 15 sporcu dahil edilmiştir. Katılımcıların demografik ve antrenman özellikleri kaydedilmiş; fiziksel performans abdominal endurans, Sorenson, lateral köprü ve lateral lomber fleksiyon testleri ile değerlendirilmiştir. Dinamik denge Y Denge Testi ile, postüral stabilite ise Tetrax postürografi sistemi kullanılarak analiz edilmiştir. Tanımlayıcı veriler medyan ve çeyrekler arası aralık olarak sunulmuş, değişkenler arasındaki ilişkiler Spearman korelasyon testi ile değerlendirilmiştir. Sporcuların medyan yaşı 20 yıl, voleybol oynama süresi ise 9 yıl olarak belirlenmiştir. Abdominal endurans testi ile Sorenson testi (r = 0.745, p = 0.001) ve lateral lomber fleksiyon testi (r = 0.722, p = 0.002) arasında güçlü pozitif ilişkiler saptanmıştır. Sorenson testi, lateral lomber fleksiyon testi (r = 0.764, p = 0.001) ve lateral köprü testi (r = 0.558, p = 0.031) ile anlamlı düzeyde ilişkili bulunmuştur. Ayrıca abdominal endurans ile sağ posterolateral Y Denge Testi performansı arasında orta düzeyde anlamlı bir ilişki gözlenmiştir (r = 0.531, p = 0.042). Sol posterolateral denge performansı ile core endurans ölçümleri arasında anlamlı ilişki saptanmamıştır (p > 0.05). Bu bulgular, kadın voleybolcularda özellikle trunk ekstansör ve abdominal kas enduransının dinamik denge performansı ile yakından ilişkili olduğunu göstermektedir.
