Abstract

Background/Objectives: This study compares muscle thickness with surface changes during bridge and plank exercises.


Methods/Statistical analysis: Twenty healthy adults participated in this study. All subjects performed plank and bridge exercises under three conditions: stable, trunk unstable, and lower extremity unstable. During the exercise, the thickness of the abdominal muscles was measured using ultrasonography. The muscle thickness in each condition was compared using repeated measures analysis of variance.


Findings: Transverse abdominis (TRA) thickness was higher in trunk unstable and lower extremity unstable than in stable, respectively (p<.05). TRA thickness was higher in trunk unstable and lower extremity unstable, respectively than in stable conditions (p<.05). In the case of internal oblique thickness, it was higher in trunk unstable compared to a stable condition (p<.05).


Improvements/Applications: The results of this study may provide information about unstable support surfaces that can be used to activate specific muscles when using plank and bridge exercises.
