LL + BFR elicited a significant (<em>p</em> = 0.025–0.046) increase in systemic pain pressure tolerance (0.77 ± 0.88 Δkgf) of the gastrocnemius as well as pain pressure threshold (0.53 ± 0.54 Δkgf) and tolerance (0.49 ± 1.02 Δkgf) of the biceps brachii, when collapsed across Time.</div></div><div><h3>Conclusions</h3><div>LL + BFR may be a repeatable, effective pain management intervention that can produce prolonged EIH.</div></div>","PeriodicalId":49698,"journal":{"name":"Physical Therapy in Sport","volume":"73 ","pages":"Pages 17-24"},"PeriodicalIF":2.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143563543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
