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.
