Investigation of the Relationship Between Trunk Muscle Endurance and Static/Dynamic Balance in Healthy Adults

Abstract

Objective: The aim of this study was to investigate the relationship between trunk muscle endurance and static/dynamic balance. Material and Method: Fifty-one individuals (29K; 22E) were included in this study. Demographic information of the participants was recorded. Trunk flexor, extensor and lateral muscle endurance tests of the individuals were performed in accordance with the McGill trunk muscle endurance test guidelines. The static balance of the individuals was evaluated with the Single Leg Stance Test, and the dynamic balance was evaluated with the Y balance test. Results: According to hierarchical regression analysis results, it was found that more trunk flexor muscle endurance was associated with higher Y balance test performance in the anterior (model 2, p<0.001, R2=0.581) and posteromedial (model 2, p=0.004, R2=0.468) directions. More trunk flexor muscle endurance was associated with higher Y balance test performance in the posterolateral direction, while older age was correlated with lower Y balance test performance in the posterolateral direction (model 2, p <0.001 and p = 0.006, R2 = 0.436, respectively). It was determined that more trunk extensor muscle endurance was correlated with higher static balance test performance (model 2, p=0.001, R2=0.318). Conclusion: It was shown that higher trunk flexor and extensor muscle endurance times were associated with better dynamic and static balance test performance in healthy adults. In addition to trunk muscle endurance, older age was also found to be associated with lower dynamic balance test performance in the posterolateral direction.

Sağlıklı Erişkinlerde Gövde Kas Enduransı ve Statik/Dinamik Denge Arasındaki İlişkinin İncelenmesi

Abstract

Amaç: Bu çalışmanın amacı sağlıklı erişkinlerde gövde kas enduransı ile statik/dinamik denge arasındaki ilişkiyi incelemekti. Gereç ve Yöntem: Bu çalışmaya 51 birey (kadın=29; erkek=22) dahil edildi. Katılımcıların demografik bilgileri kaydedildi. Bireylerin gövde fleksör, ekstansör ve lateral kas endurans testleri McGill gövde kas endurans testi rehberine uygun olarak yapıldı. Bireylerin statik dengesi tek ayak üzerinde durma testi ile, dinamik dengesi ise Y denge testi ile değerlendirildi. Bulgular: Hiyerarşik regresyon analiz sonuçlarına göre, daha fazla gövde fleksör kas enduransının anterior (model 2, p<0,001, R2=0,581) ve posteromedial (model 2, p=0,004, R2=0,468) yönlerde daha yüksek Y denge test performansı ile ilişkili olduğu bulundu. Daha fazla gövde fleksör kas enduransı, posterolateral yönde daha yüksek Y denge test performansı ile ilişkili iken, ileri yaşın posterolateral yönde daha düşük Y denge test performansı ile ilişkili olduğu belirlendi (model 2, sırasıyla p<0,001 ve p=0,006, R2=0,436). Daha fazla gövde ekstansör kas enduransının daha yüksek statik denge test performansı ile ilişkili olduğu saptandı (model 2, p=0,001, R2=0,318). Sonuç: Sağlıklı erişkinlerde daha yüksek gövde fleksör ve ekstansör kas endurans sürelerinin daha iyi dinamik ve statik denge test performansı ile ilişkili olduğu gösterildi. Gövde kas enduransına ek olarak, ileri yaşın ise posterolateral yönde daha düşük dinamik denge test performansı ile ilişkili olduğu bulundu.
