However, no studies have yet elucidated the precise effects of CFP shapes on the lower limb biomechanical characteristics subsequent to running-induced fatigue. The purpose of this study was to investigate the effects of different CFP shapes in running shoes on the lower limb biomechanics of runners following running-induced fatigue. 12 male runners (aged 21.8 \u00b1 1.3\u00a0years, mass 59.1 \u00b1 4.1\u00a0kg, height 168.9 \u00b1 2.2\u00a0cm, weekly running distance 68.8 \u00b1 5.5\u00a0km\/week) were recruited for this study. Two-way repeated measures ANOVA was used to compare kinematic and kinetic data, while SPM (Statistical Parametric Mapping) was used to assess the activation levels of lower limb muscles. Compared to wearing flat CFP shoes (\u201cFlat\u201d), wearing curved CFP shoes (\u201cCurve\u201d) resulted in a significant reduction in the hip (p = 0.034) and knee contact angle (p &amp;lt; 0.000), as well as a significant decrease in the hip flexion moment (p = 0.008). The activation level of the tibialis anterior (TA) was significantly higher when wearing \u201cCurve\u201d in pre-fatigue compared to \u201cFlat\u201d, whereas the opposite was observed post-fatigue. The curved CFP altered the bending angle of the forefoot, thereby significantly reducing the joint angles and joint moments of the hip and knee.<\/jats:p>","DOI":"10.3389\/fbioe.2025.1539976","type":"journal-article","created":{"date-parts":[[2025,2,11]],"date-time":"2025-02-11T02:02:22Z","timestamp":1739239342000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":13,"title":["The effects of different carbon-fiber plate shapes in shoes on lower limb biomechanics following running-induced fatigue"],"prefix":"10.3389","volume":"13","author":[{"given":"Yufan","family":"Xu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chengyuan","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yufei","family":"Fang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenghui","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Song","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen","family":"Hu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaodong","family":"Gu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,2,11]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"815675","DOI":"10.3389\/fspor.2022.815675","article-title":"Running injury paradigms and their influence on footwear design features and runner assessment methods: a focused review to advance evidence-based practice for running medicine clinicians","volume":"4","author":"Agresta","year":"2022","journal-title":"Front.
