While DRA usually resolves post-childbirth, some women experience persistent issues. Exercise may help reduce the inter-rectus distance, though more research is needed.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Objectives<\/jats:title>\n<jats:p>Analyze the immediate and long-term effects of hypopressive and conventional abdominal exercises on inter-rectus distance (IRD) in postpartum women, focusing on parity differences.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Methods<\/jats:title>\n<jats:p>Twenty-eight women who met specific inclusion criteria were randomly assigned to either the hypopressive group (n = 14) or the conventional group (n = 14). The exercise programs for both groups lasted 6 weeks. Ultrasound measurements were taken of the IRD at two locations above the umbilicus, 2 cm (AB2) and 5 cm (AB5), before and after exercise programs.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Results<\/jats:title>\n<jats:p>The IRD decreased after both exercise programs compared to baseline measurements in AB2 (mean difference: 3.06 mm, 95% CI: 1.06 to 5.05) and in AB5 (mean difference: 2.88 mm, 95% CI: 1.59 to 4.17), confirming the long-term effect of exercise. No differences were found between the application of the conventional exercise program or the hypopressive exercises, indicating that both had a similar positive effect.<\/jats:p>\n<jats:p>Regarding the immediate effect, after the performance of both programs, the IRD was greater during rest compared to abdominal contraction. This effect was more pronounced at AB5 location (mean difference: 1.00mm, 95% CI: 0.97 to 1.89). Conventional exercises result in a reduction during resting condition (mean difference: 4.52mm, 95% CI: 2.62 to 6.79), whereas with hypopressive exercises, the reduction occurs during muscle contraction (mean difference: 3.43mm, 95% CI: 1.21 to 5.65).<\/jats:p>\n<jats:p>With regard to parity, multiparous women benefit most from the application of exercise programs.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec005\">\n<jats:title>Conclusion<\/jats:title>\n<jats:p>A reduction in IRD has been achieved with the implementation of both exercise programs in postpartum women, with multiparous women benefiting the most. Specifically, at 5 cm above umbilicus, conventional exercises result in a reduction during the rest condition, whereas with hypopressive exercises, the reduction occurs during muscle contraction.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec006\">\n<jats:title>Trial registration<\/jats:title>\n<jats:p><jats:bold>Clinical trial registration<\/jats:bold>: <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/clinicaltrials.gov\/ct2\/show\/NCT05439668\" xlink:type=\"simple\">NCT05439668<\/jats:ext-link>.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0314274","type":"journal-article","created":{"date-parts":[[2024,12,12]],"date-time":"2024-12-12T18:39:23Z","timestamp":1734028763000},"page":"e0314274","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":8,"title":["Effect of hypopressive and conventional abdominal exercises on postpartum diastasis recti: A randomized controlled trial"],"prefix":"10.1371","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6541-988X","authenticated-orcid":true,"given":"Mercedes","family":"Soto-Gonz\u00e1lez","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9507-789X","authenticated-orcid":true,"given":"Iria","family":"Da Cu\u00f1a-Carrera","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5625-7628","authenticated-orcid":true,"given":"Eva Mar\u00eda","family":"Lantar\u00f3n-Caeiro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7389-1452","authenticated-orcid":true,"given":"Augusto Gil","family":"Pascoal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2024,12,12]]},"reference":[{"key":"pone.0314274.ref001","doi-asserted-by":"crossref","first-page":"163","DOI":"10.3109\/2000656X.2013.859145","article-title":"Rectus abdominis diastasis","volume":"48","author":"J Akram","year":"2014","journal-title":"J Plast Surg Hand Surg"},{"key":"pone.0314274.ref002","doi-asserted-by":"crossref","first-page":"97","DOI":"10.5603\/GP.a2018.0016","article-title":"Diastasis recti abdominis\u2014a review of treatment methods","volume":"89","author":"A Michalska","year":"2018","journal-title":"Ginekol Pol"},{"key":"pone.0314274.ref003","doi-asserted-by":"crossref","first-page":"59","DOI":"10.2174\/157340481101150914201735","article-title":"Diastasis Recti Abdominis in Pregnancy and Postpartum Period.
