Fascial flossing\u2014a compressive myofascial technique\u2014has gained attention as a potential intervention; however, evidence on its role in post-fatigue recovery remains limited.<\/jats:p>\n Hypothesis\/Purpose: To determine whether lower-leg fascial flossing improves fascial gliding, flexibility, perceived tightness, and jump performance following running-induced fatigue.<\/jats:p>\n <\/jats:sec>\n \n Study Design<\/jats:title>\n Randomized controlled cross-over study.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Nationally competitive male collegiate long-distance runners were recruited from a university track and field team via institutional and verbal announcements. Participants completed a treadmill fatigue protocol followed by unilateral lower-leg fascial flossing, with the contralateral leg serving as control. Pre- and post-intervention assessments included ankle dorsiflexion range of motion (Weight-Bearing Lunge Test), perceived tightness (Visual Analog Scale), myofascial gliding via ultrasound cross-correlation analysis, and Reactive Strength Index from repeated rebound jumps. Statistical analysis was performed using a mixed-model repeated-measures analysis to examine condition \u00d7 time interactions.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Seventeen nationally competitive male collegiate distance runners (mean age 20.1 \u00b1 0.8 years) completed the protocol. Significant condition \u00d7 time interactions were observed for all outcomes. Perceived tightness decreased in the flossed leg but increased in the control leg (p = 0.0499, partial \u03b7\u00b2 = 0.101). Both legs improved dorsiflexion ROM, with greater gains in the flossed leg (p = 0.0084, partial \u03b7\u00b2 = 0.085). RSI declined in the control leg, while the flossed leg maintained performance levels (p = 0.0043, partial \u03b7\u00b2 = 0.109). Myofascial gliding improved only in the flossed leg (p = 0.0093, partial \u03b7\u00b2 = 0.091), suggesting enhanced tissue mobility.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Lower-leg fascial flossing enhanced flexibility, reduced tightness, and preserved jump performance after running-induced fatigue. This technique may represent a practical, low-cost, and time-efficient recovery strategy for endurance athletes and practitioners seeking to optimize post-exercise recovery.<\/jats:p>\n <\/jats:sec>\n \n Level of Evidence<\/jats:title>\n Level 2.<\/jats:p>\n <\/jats:sec>","DOI":"10.26603\/001c.158518","type":"journal-article","created":{"date-parts":[[2026,4,1]],"date-time":"2026-04-01T01:06:35Z","timestamp":1775005595000},"source":"Crossref","is-referenced-by-count":0,"title":["Effects of Lower-Leg Fascial Flossing on Flexibility and Performance in Collegiate Distance Runners: Ultrasound Evaluation of Fascial Gliding"],"prefix":"10.26603","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4748-7293","authenticated-orcid":true,"given":"Yuki","family":"Nakai","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0510mg863","id-type":"ROR","asserted-by":"publisher"}],"name":"Reiwa Health Sciences University","department":["Department of Physical Therapy, Faculty of Rehabilitation"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasufumi","family":"Takeshita","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02v6fyw83","id-type":"ROR","asserted-by":"publisher"}],"name":"Daiichi Institute of Technology","department":["Department of Information, Artificial Intelligence and Data Science"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryota","family":"Shibusawa","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02v6fyw83","id-type":"ROR","asserted-by":"publisher"}],"name":"Daiichi Institute of Technology","department":["Department of Information, Artificial Intelligence and Data Science"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katsutoshi","family":"Oe","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02wp4vw89","id-type":"ROR","asserted-by":"publisher"}],"name":"Nippon Bunri University","department":["Department of Mechanical and Electrical Engineering, Faculty of Engineering"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"11140","published-online":{"date-parts":[[2026,4,2]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"666129","DOI":"10.3389\/fphys.2021.666129","article-title":"Effects of tissue flossing on the healthy and impaired musculoskeletal system: a scoping review","volume":"12","author":"A.
