Effects of Abdominal Bracing Versus Abdominal Hollowing on Abdominal Muscle Thickness and Activation During Static and Dynamic Trunk Stabilization Tasks in Healthy Adults

Key Points

• This research aims to compare the effects of abdominal bracing and abdominal hollowing on muscle thickness and activation during stabilization tasks.
• Conducted experiments on healthy adults
• Compared effects of two techniques: bracing and hollowing
• Evaluated muscle activation and thickness during both static and dynamic tasks
• Abdominal bracing resulted in greater muscle activation than hollowing
• Increased muscle thickness observed with bracing during stabilization tasks
• Dynamic tasks showed varied activation levels between both techniques
