“…Regarding waist circumference, we did not find statistically significant differences in the ADIM group with respect to EFCD group. Choi et al [27] reported that there is a relationship between abdominal muscle training and decreased waist circumference; however, it would be necessary to study in more depth the relationship between the type of contraction or exercise and the decrease in waist circumference. In addition, Rostami et al [28] reported that waist circumference might be assumed as a good parameter to evaluate the abdominal muscles.…”

“…Waist circumference was measured with the participant in supine decubitus with a 45 • hip flexion; the measuring tape was placed at the level of the bellybutton, taking as reference the midpoint between the last rib and the upper edge of the iliac crest [27], passing it behind the back and around the waist [28]. The following measurements were obtained: (1) Three measurements at rest, at the end of normal expiration [27]; (2) Three measurements at the end of each ADIM, with each maneuver lasting 10 s; (3) Three measurements at the end of expiration through the EFCD, with each expiration lasting 10 s. The mean of each of the 3 measurements in the different situations was later analyzed, and the percent of change between rest and activation was calculated.…”

Background and Objectives: The purpose of the present study was to quantify and compare lateral abdominal musculature thickness, including the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) muscles, via rehabilitative ultrasound imaging (RUSI) during the use of the expiratory flow control device (EFCD) versus the classic abdominal drawing-in maneuver (ADIM). Materials and Methods: A cross-sectional observational pilot study. Twenty-one women were recruited and assessed the thickness of each muscle (TrA, IO, and EO) by ultrasound imaging at rest, during the ADIM, and during expiration with the EFCD. Waist circumference was also measured under the same circumstances. Results: Statistically significant differences were observed between ADIM, EFCD, and at rest condition for the thickness of the TrA (p = 0.001) and IO (p = 0.039). Moreover, statistically significant differences for TrAb at rest compared with the ADIM (p = 0.001, Cohen’s d = 2.183) and at rest and with the EFCD (p = 0.001, Cohen’s d = 2.843). In addition, between ADIM and EFCD were not statistically significant, although a moderate effect size was found (p = 0.055, Cohen’s d = 0.694). For the IO muscle thickness, significant differences were reported between the EFCD and at rest (p = 0.038), Cohen’s d = 0.081). Conclusions: Significant differences in the increase of the thickness of the TrA and IO muscles during the use of the EFCD and the ADIM with respect to rest. In addition, for the TrA, statistically significant differences were found during expiration with the EFCD with respect to the ADIM. Expiration with EFCD can be a useful method for the activation of the TrA.
