“…Prior studies have reported the effects of breathing in the abdominal muscles’ thickness, with similar findings in TrA and IO but different results in RA and EO [ 14 , 15 , 19 , 24 , 25 ], which suggest different activations probably due to the position. Moreover, a recent study analyzed the abdominal muscle thickness during breathing in subjects with and without CLBP [ 20 ], reporting thicker TrA and EO and greater IO and RA in subjects with pain. These results are contrary to our findings in subjects with CLBP, suggesting that TrA and IO increased the muscle thickness during breathing, but RA decreased its muscle thickness in these subjects with pain.…”

“…These results are contrary to our findings in subjects with CLBP, suggesting that TrA and IO increased the muscle thickness during breathing, but RA decreased its muscle thickness in these subjects with pain. These different results could be due to differences in measuring, in the type of breathing or in the sample size, but the most remarkable difference is that Arab et al [ 20 ] only included males in their sample. CLBP has been reported as a prevalent disfunction, with a higher incidence in women in comparison with men [ 1 , 2 , 26 ].…”

“…The sample size was calculated with the G*Power software (version 3.1, HHU, Düsseldorf, Germany), with a power of 0.95 and an α error of 0.05. Data from Arab et al [ 20 ] were selected, using the variable “thickness at the end of expiration” in the internal oblique (IO) and comparing the groups with (9.53 ± 1.35 mm) and without (8.35 ± 1.63 mm) CLBP. A sample of 20 subjects was estimated as the minimum per group to obtain consistent results.…”

“…Nevertheless, these studies did not consider subjects with lumbar disorders and thus the effects of CLBP on the thickness of abdominal muscles appears to be unclear. In this context, a recent investigation analyzed the activity of the abdominal muscles during breathing with ultrasonography in males with and without CLBP [ 20 ]. Findings of this investigation suggested that abdominal muscles change differently in males with and without CLBP, with less activity of the external oblique (EO) and greater activity of the rectus abdominis (RA).…”

Chronic low back pain (CLBP) is a prevalent disfunction in the spine, affecting both women and men. The implication of the abdominal muscles in this disfunction has been studied, including wrong breathing patterns or inactivity of this area. However, there is a lack of studies examining changes in thickness of abdominal with ultrasonography. Thus, the aim of this study is to analyze the differences in the thickness of abdominal muscles at rest and during breathing between subjects with and without CLBP. A total of 72 subjects were divided in two groups: participants with CLBP (n = 36) and participants without CLBP (n = 36). In both groups, the thickness of the four abdominal muscles was measured and compared at rest and during breathing with ultrasonography. In TrA and IO there were no significant differences between groups, but those subjects with CLBP increased the muscle thickness more than participants without pain during breathing. In EO there were no differences in muscle thickness between groups and between rest and breathing. In RA, subjects with CLBP showed less muscle thickness than subjects without pain during breathing, but no changes were found at rest. In conclusion, the deepest abdominal muscles, TrA and IO, appear to increase their thickness and RA appear to decrease more in subjects with CLBP, in comparison with healthy participants.

“…Muscle thickness was defined as the distance between the inside edges of each muscle border [15]. To assess the muscle at the end of inspiration and expiration, patients were instructed to inhale/exhale normally and hold their breath until the examiner took the images [29]. To assess the contraction time of the abdominal muscles, patients were asked to perform isometric ipsilateral hip flexion whilst lying in supine [30].…”

Coronavirus disease (Covid-19) is a highly infectious disease caused by the SARS-CoV-2 virus and is associated with a decrease of respiratory, physical, and psychological function, subsequently affecting quality of life. The aim of the present pilot study was to use ultrasound imaging (USI) to evaluate and compare the thickness of the diaphragm and abdominal muscles between individuals recently diagnosed with moderate Covid-19 infection and healthy individuals. Methods: A cross-sectional observational pilot study was performed. A total sample of 24 participants were recruited from a private medical center (Madrid, Spain): Covid-19 (n = 12) and healthy controls (n = 12). The external oblique (EO), internal oblique (IO), transversus abdominis (TrA), rectus abdominis (RA), interrecti distance (IRD) and diaphragm thickness were assessed using USI during inspiration, expiration and during contraction. Results: USI measurements of the thickness of EO, IO, TrA, RA, IRD and the diaphragm did not differ significantly between groups during inspiration, expiration or during contraction (all P > 0.05). Conclusions: These preliminary results suggest that the morphology of the abdominal muscles and diaphragm is not altered in people with a recent history of moderate Covid-19 infection.

We aimed to assess the effects of interaction between several breathing patterns and postures on abdominal muscle activation and intra-abdominal pressure (IAP). This comparative cross-sectional study enrolled fourteen healthy university students majoring in sports science and/or physical education. They performed four active breathing tasks: quiet nasal breathing (Q-Bre), nasal deep breathing (Deep-Bre), completely forced expiration (Forced-Expi), and exertional nasal inhalation with abdominal muscles with isometric contraction (Exertion-Inspi) in the elbow-toe plank and supine postures. Breathing volume; IAP; and transverse abdominis-internal oblique muscle (TrA-IO) and external oblique muscle (EO) activities were recorded. Abdominal muscle activity and IAP significantly interacted with breathing pattern and postures during the expiratory phase (p < 0.05). In the inspiratory phase, TrA-IO activity was significantly affected by breathing pattern and EO activity with posture (p < 0.05). TrA-IO activity significantly increased during Forced-Expi in the supine posture (47.6% of the maximum voluntary contraction) and Exertion-Inspi in the elbow-toe posture (35.7%), whereas no differences were found during Deep-Bre or Q-Bre (< 20%). EO activity increased in the elbow-toe posture (22.5–30.6%) compared with that in the supine posture (< 5%) during all breathing tasks. IAP values were low during all tasks (< 15%) except for Forced-Expi (24.9%). Abdominal muscle activation and IAP interacted with the breathing pattern and posture.
