Ten untrained men (21\u201039\u00a0years) performed two bouts of 10 sets of 6 maximal isokinetic eccentric contractions of the elbow flexors in the supinated position for one arm and neutral position for the other arm separated by 2\u00a0weeks in a randomized order. Biceps brachii myotendinous junction (MTJ) movements during eccentric contractions were recorded by B\u2010mode ultrasonography, and the displacement from the start to end of each contraction was quantified. Peak torque (supinated: 367.8\u00a0\u00b1\u00a0112.5 Nm, neutral: 381.5\u00a0\u00b1\u00a0120.4 Nm) and total work (1816\u00a0\u00b1\u00a0539\u00a0J, 1865\u00a0\u00b1\u00a0673\u00a0J) produced during eccentric contractions were similar between conditions. The average MTJ displacement increased (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.05) from the 1st set (8.0\u00a0\u00b1\u00a02.0\u00a0mm) to 10th set (15.8\u00a0\u00b1\u00a01.9\u00a0mm) for the supinated condition, but no such increase was found in the neutral condition (1st set: 5.1\u00a0\u00b1\u00a01.0\u00a0mm, 10th set: 5.0\u00a0\u00b1\u00a00.8\u00a0mm). Changes in indirect muscle damage markers (maximal voluntary isometric contraction torque, range of motion, serum creatine kinase activity, and muscle soreness) after exercise were greater (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.05) for the supinated than neutral condition. These results suggest that the greater muscle damage marker changes for the supinated than neutral wrist position was associated with the greater muscle lengthening (strain).<\/jats:p>","DOI":"10.1111\/sms.13936","type":"journal-article","created":{"date-parts":[[2021,2,12]],"date-time":"2021-02-12T17:54:02Z","timestamp":1613152442000},"page":"1290-1300","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Effects of wrist position on eccentric exercise\u2010induced muscle damage of the elbow flexors"],"prefix":"10.1111","volume":"31","author":[{"given":"Wing Yin","family":"Lau","sequence":"first","affiliation":[{"name":"Centre for Exercise and Sports Science Research School of Medical and Health Sciences Edith Cowan University Joondalup WA Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1664-1614","authenticated-orcid":false,"given":"Anthony J.","family":"Blazevich","sequence":"additional","affiliation":[{"name":"Centre for Exercise and Sports Science Research School of Medical and Health Sciences Edith Cowan University Joondalup WA Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael J.","family":"Newton","sequence":"additional","affiliation":[{"name":"Centre for Exercise and Sports Science Research School of Medical and Health Sciences Edith Cowan University Joondalup WA Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sam Shi Xuan","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Health and Medical Sciences Faculty of Health, Arts and Design Swinburne University of Technology Hawthorn Vic.
