Variations in abdominal muscle activities of obese females during abdominal bracing exercise in different body positions.

Aims: This study evaluated the activities of the Rectus Abdominis (RA) and Transversus Abdominis (TrA) muscles during abdominal bracing exercises (ABE) in different body positions.

Methodology: Electrical activities of both components of the RA and TrA muscles were assessed respectively in 25 obese females via surface electromyography during ABE in four (4) different body positions (crook lying, side lying, standing, and sitting). Each trial lasted for five (5) seconds with an hour rest period between trials.
