A total of 38 participants were randomly assigned to either BDJ or BFR-BDJ training for 8 weeks. Quadriceps peak torque, total work, and single-leg stance stability under eyes-open and eyes-closed conditions were assessed using isokinetic dynamometry and force-platform measures. Compared with BDJ alone, BFR-BDJ produced significantly greater improvements in quadriceps strength and reductions in sway velocity during eyes-open stance. No between-group differences were observed under eyes-closed conditions, suggesting visual dependence in balance enhancement. No adverse events occurred. These findings indicate that integrating BFR with BDJ provides a low-intensity yet effective training strategy to improve lower-limb neuromuscular performance and functional stability in individuals unable or unwilling to engage in high-load exercise.<\/jats:p>","DOI":"10.1038\/s41598-026-53706-x","type":"journal-article","created":{"date-parts":[[2026,8,3]],"date-time":"2026-08-03T14:02:42Z","timestamp":1785765762000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of blood flow restriction\u2013augmented baduanjin training on quadriceps strength and postural stability in sedentary young men: a randomized controlled trial"],"prefix":"10.1038","volume":"16","author":[{"given":"Wenbo","family":"Ren","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuanpeng","family":"Liao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenhua","family":"Jin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiahuan","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenshi","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,8,3]]},"reference":[{"key":"53706_CR1","doi-asserted-by":"publisher","first-page":"365","DOI":"10.4082\/kjfm.20.0165","volume":"41","author":"JH Park","year":"2020","unstructured":"Park, J.
