Strength training may achieve higher adherence rates, but its preventive effect has not been sufficiently evaluated in randomized clinical trials. The objective of this trial is to evaluate the effect of a strength training program in pregnant women with overweight or obesity on the incidence of gestational diabetes mellitus and other outcomes (obstetric and quality of life).<\/jats:p>\n <\/jats:sec>\n \n Material and Methods<\/jats:title>\n \n A randomized clinical trial including 209 pregnant women (body mass index \u226525\u2009kg\/m\n 2<\/jats:sup>\n ). The intervention group followed a strength training program from gestational weeks 12\u201314 until week 36 or delivery, combining supervised and home\u2010based sessions. The primary outcome was gestational diabetes incidence; secondary outcomes included gestational weight gain, macrosomia, physical activity, quality of life, and pregnancy symptoms. Trial Registration\n ClinicalTrials.gov<\/jats:ext-link>\n NCT05840497.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Forty\u2010eight per cent of participants in the intervention group achieved the adherence target. The intervention group showed lower incidences of gestational diabetes and hydramnios, with absolute risk differences of \u22125.3% (95% CI: \u221212.5 to 0.5;\n p<\/jats:italic>\n \u2009=\u20090.07) and \u22124.5% (95% CI: \u221211.0 to 2.0;\n p<\/jats:italic>\n \u2009=\u20090.05), respectively. No significant differences in fetal macrosomia were observed in the intention\u2010to\u2010treat analysis. In the per\u2010protocol analysis, the incidence of GDM was 0% in the adherent intervention group and 7.3% in the control group (risk difference \u22127.3 [95% CI: \u221214.3, 3.0];\n p<\/jats:italic>\n \u2009=\u20090.09), and no cases of macrosomia were recorded in the adherent intervention group, compared with 6.3% in the control group (difference \u22126.3 [95% CI: \u221213.1 to 4.5];\n p<\/jats:italic>\n \u2009=\u20090.1).\n <\/jats:p>\n \n The intervention group showed significant improvements in quality of life (mean difference: 8.4; 95% CI: 4.9\u201311.9;\n p<\/jats:italic>\n \u2009<\u20090.001) and reported lower frequency and impact of pregnancy symptoms. No differences were observed in adverse events, including preterm birth.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Strength training during pregnancy improved maternal quality of life and reduced pregnancy\u2010related symptom burden. Although the primary outcome did not reach statistical significance, consistent trends toward lower rates of gestational diabetes and related outcomes, particularly among adherent women, suggest a potential preventive effect that should be confirmed in larger trials.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/aogs.70336","type":"journal-article","created":{"date-parts":[[2026,8,19]],"date-time":"2026-08-19T07:01:29Z","timestamp":1787122889000},"page":"2315-2324","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Strength training during pregnancy for the prevention of gestational diabetes: A randomized trial in women with overweight or obesity"],"prefix":"10.1111","volume":"105","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-0520-1906","authenticated-orcid":false,"given":"Teresa E.","family":"Santa Cruz","sequence":"first","affiliation":[{"name":"Department of Gynecology and Obstetrics Hospital Universitario de Donostia San Sebastian Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8631-9981","authenticated-orcid":false,"given":"Cristina","family":"Sarasqueta","sequence":"additional","affiliation":[{"name":"Department of Clinical Epidemiology Donostia University Hospital San Sebasti\u00e1n Spain"},{"name":"Biogipuzkoa Health Research Institute San Sebasti\u00e1n Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan Carlos","family":"Muruz\u00e1bal","sequence":"additional","affiliation":[{"name":"Department of Gynecologic and Obstetrics Hospital Universitario de Navarra Pamplona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olga","family":"Sanz","sequence":"additional","affiliation":[{"name":"Department of Gynecology and Obstetrics Hospital Reina Sof\u00eda Tudela Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,19]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.7717\/peerj.13067"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2458-7-168"},{"key":"e_1_2_13_4_1","doi-asserted-by":"publisher","DOI":"10.1089\/met.2006.4.84"},{"key":"e_1_2_13_5_1","volume-title":"Obesity in pregnancy: complications and maternal management","author":"Lockwood CJ","year":"2022"},{"key":"e_1_2_13_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/14651858.CD012394.pub3"},{"key":"e_1_2_13_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/birt.12396"},{"key":"e_1_2_13_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/aogs.13087"},{"key":"e_1_2_13_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/ijgo.14741"},{"key":"e_1_2_13_10_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12884-024-07021-w"},{"key":"e_1_2_13_11_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjdrc-2021-002622"},{"key":"e_1_2_13_12_1","doi-asserted-by":"publisher","DOI":"10.1177\/19417381231189730"},{"key":"e_1_2_13_13_1","doi-asserted-by":"publisher","DOI":"10.1080\/14767058.2024.2421278"},{"key":"e_1_2_13_14_1","doi-asserted-by":"publisher","DOI":"10.7326\/M17-0046"},{"key":"e_1_2_13_15_1","volume-title":"EPIDAT: program for epidemiological data analysis [In Spanish].
