Muscle damage responses to resistance exercise performed with high-load versus low-load associated with partial blood flow restriction in young women
The aim of this study was to compare if an acute exercise session of high-load resistance training (HL-RT, e.g. 70% of 1 repetition-maximum, 1 RM) induces a higher magnitude of muscle damage compared with a RT protocol with low-loads (e.g. 20% 1 RM) associated with partial blood flow restriction (LL...

| description | The aim of this study was to compare if an acute exercise session of high-load resistance training (HL-RT, e.g. 70% of 1 repetition-maximum, 1 RM) induces a higher magnitude of muscle damage compared with a RT protocol with low-loads (e.g. 20% 1 RM) associated with partial blood flow restriction (LL-BFR), and investigate the recovery in the days after the protocols. We used an unilateral crossover research design in which 10 young women (22(2) y; 162(5) cm; 66(11) kg) performed HL-RT and LL-BFR in a randomized, counterbalanced manner with a minimum interval of 2 weeks between protocols. Indirect muscle damage markers were evaluated before and once a day for 4 days into recovery. Main results showed decreases of 8-12% at 24-48 h in maximal voluntary isometric and concentric contraction torques (P |

Moreover, delayed onset muscle soreness increased only after LL-BFR (P < 0.001). We conclude that an acute bout of low volume HL-RT or LL-BFR to failure resulted in edema-induced muscle swelling, but do not induce major or long-lasting decrements in muscle function and the level of soreness promoted from LL-BFR was mild. </description><identifier>ISSN: 1746-1391</identifier><identifier>EISSN: 1536-7290</identifier><identifier>DOI: 10.1080/17461391.2019.1614680</identifier><identifier>PMID: 31043129</identifier><language>eng</language><publisher>England: Routledge</publisher><subject>muscle soreness ; musculoskeletal ; Occlusion training ; physiology ; recovery ; strength</subject><ispartof>European journal of sport science, 2020-02, Vol.20 (1), p.125-134</ispartof><rights>2019 European College of Sport Science 2019</rights><rights>European College of Sport Science</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c4219-3d923bfc4e791241ef1c5fcfae264fc8bbf95bf345bd5dc43394d686611317d73</citedby><cites>FETCH-LOGICAL-c4219-3d923bfc4e791241ef1c5fcfae264fc8bbf95bf345bd5dc43394d686611317d73</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://www.tandfonline.com/doi/pdf/10.1080/17461391.2019.1614680$$EPDF$$P50$$Ginformaworld$$H</linktopdf><linktohtml>$$Uhttps://www.tandfonline.com/doi/full/10.1080/17461391.2019.1614680$$EHTML$$P50$$Ginformaworld$$H</linktohtml><link.rule.ids>314,780,784,27924,27925,59647,60436</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/31043129$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Alvarez, Ieda Fernanda</creatorcontrib><creatorcontrib>Damas, Felipe</creatorcontrib><creatorcontrib>Biazon, Thaís Marina Pires de</creatorcontrib><creatorcontrib>Miquelini, Maiara</creatorcontrib><creatorcontrib>Doma, Kenji</creatorcontrib><creatorcontrib>Libardi, Cleiton Augusto</creatorcontrib><title>Muscle damage responses to resistance exercise performed with high-load versus low-load associated with partial blood flow restriction in young women</title><title>European journal of sport science</title><addtitle>Eur J Sport Sci</addtitle><description>The aim of this study was to compare if an acute exercise session of high-load resistance training (HL-RT, e.g. 70% of 1 repetition-maximum, 1 RM) induces a higher magnitude of muscle damage compared with a RT protocol with low-loads (e.g. 20% 1 RM) associated with partial blood flow restriction (LL-BFR), and investigate the recovery in the days after the protocols.
