This study aimed to compare the effects of intermittent and continuous stretching for the same duration on the range of motion (ROM), passive resistive torque (PRT), and musculotendinous stiffness (MTS) of ankle plantar flexors. Eighteen healthy young men participated in the study. Intermittent (four sets \u00d7 30 s) and continuous stretching (one set \u00d7 120 s) were performed in random orders on two separate days. Both stretching protocols were conducted using a dynamometer with a constant torque applied. ROM and PRT were determined using a dynamometer, and MTS was calculated using the torque\u2013angle relationship measured before and after stretching. Two-way repeated measures analysis of variance was performed for all parameters. Both intermittent and continuous stretching significantly increased ROM and decreased PRT and MTS (p &lt; 0.05). Intermittent stretching led to greater changes in ROM and PRT than continuous stretching. However, the reduction in MTS did not differ between the two conditions. These results suggest that intermittent stretching is more effective in increasing ROM and changing the mechanical properties of the musculotendinous complex.<\/jats:p>","DOI":"10.3390\/ijerph182010632","type":"journal-article","created":{"date-parts":[[2021,10,11]],"date-time":"2021-10-11T09:16:42Z","timestamp":1633943802000},"page":"10632","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Effects of Intermittent and Continuous Static Stretching on Range of Motion and Musculotendinous Viscoelastic Properties Based on a Duration-Matched Protocol"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1224-3416","authenticated-orcid":false,"given":"Kensuke","family":"Oba","sequence":"first","affiliation":[{"name":"Graduate School of Health Sciences, Hokkaido University, Sapporo 060-0812, Japan"},{"name":"Department of Rehabilitation, Hitsujigaoka Hospital, Sapporo 004-0021, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4663-598X","authenticated-orcid":false,"given":"Mina","family":"Samukawa","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University, Sapporo 060-0812, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yosuke","family":"Abe","sequence":"additional","affiliation":[{"name":"Graduate School of Health Sciences, Hokkaido University, Sapporo 060-0812, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yukino","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation, Hokushin Orthopaedic Hospital, Sapporo 060-0908, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miho","family":"Komatsuzaki","sequence":"additional","affiliation":[{"name":"Graduate School of Health Sciences, Hokkaido University, Sapporo 060-0812, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2764-1927","authenticated-orcid":false,"given":"Satoshi","family":"Kasahara","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University, Sapporo 060-0812, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0174-7416","authenticated-orcid":false,"given":"Tomoya","family":"Ishida","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University, Sapporo 060-0812, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harukazu","family":"Tohyama","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University, Sapporo 060-0812, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"709","DOI":"10.1519\/JSC.0000000000002767","article-title":"Influence of Constant Torque Stretching at Different Stretching Intensities on Flexibility and Mechanical Properties of Plantar Flexors","volume":"35","author":"Oba","year":"2021","journal-title":"J.
