There are many proposed core stability exercises in a variety of posi-tions; however, it is not clear that in which position, activation of trans-verse abdominis muscle is utmost. We aimed to compare the activation of transverse abdominis muscle in different core stability exercise posi-tions through ultrasound imaging. in a 20 subjects’ study we compared the effectiveness of drawing-in and bracing maneuvers on transverse abdominis in different core stability exercise positions (supine, hook ly-ing, supine with 90° flexed knee and hip, supine with stretched knees and 90° flexed hips, bridge, bridge with one stretched knee and Bird dog). We used activation ratio and preferential activation ratio as mea-surements of transverse abdominis activation. Abdominal Bracing in the bridge position showed the highest activation of transverse abdom-inis (P<0.05). The results showed significantly higher activation of trans-verse abdominis, measured by preferential activation ratio, in bridge position during abdominal bracing.
