Paired-sample t-tests assessed changes in discrete parameters of joint stiffness, loading rates, and time-varying parameters were compared with one-dimensional statistical parametric mapping.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Fatigue significantly reduced the range of motion (ROM) during landing, with significant differences in angles, specifically the dorsi-plantar flexion of right ankle, flexion-extension of left hip, rotation of left knee, and adduction-abduction of right knee (P&lt;0.001). The first loading rate at touchdown decreased by 10%, and the time intervals between the first and second peak and the second and third peak reduced by 40% and 80%, respectively. Joint loading increased and the sagittal joint stiffness of left hip, right knee, and right ankle exhibited significant differences post-fatigue (P&lt;0.001). Knee joint reduced the flexion angle (P&lt;0.001) and the load of knee joint (P&lt;0.001) during post-fatigue, with the role compensated by hip and ankle joints to achieve balance in the lower limb kinetic chain.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>These findings provide pilot evidence that running fatigue may lead to changes in lower limb joint loadings and provide a scientific foundation for fatigue prediction and injury assessment.<\/jats:p><\/jats:sec>","DOI":"10.37190\/abb\/209529","type":"journal-article","created":{"date-parts":[[2025,8,21]],"date-time":"2025-08-21T21:00:30Z","timestamp":1755810030000},"page":"61-75","source":"Crossref","is-referenced-by-count":2,"title":["Alterations of landing biomechanics from an inclined treadmill running-induced fatigue protocol"],"prefix":"10.37190","volume":"27","author":[{"given":"Hanhui","family":"Jiang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kui","family":"Wan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1113-877X","authenticated-orcid":false,"given":"Qichang","family":"Mei","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zixiang","family":"Gao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justin","family":"Fernandez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaodong","family":"Gu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"23140","published-online":{"date-parts":[[2025,8,21]]},"container-title":["Acta of Bioengineering and Biomechanics"],"original-title":[],"link":[{"URL":"https:\/\/actabio.pwr.edu.pl\/fcp\/xGBUKOQtTKlQhbx08SlkTUARAUWRuHQwFDBoIVURNWHxSBlhnRlUuWTISTnoYDxMe\/302\/public\/publikacje\/v27-3-2025\/46.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/actabio.pwr.edu.pl\/fcp\/xGBUKOQtTKlQhbx08SlkTUARAUWRuHQwFDBoIVURNWHxSBlhnRlUuWTISTnoYDxMe\/302\/public\/publikacje\/v27-3-2025\/46.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T20:12:34Z","timestamp":1760991154000},"score":1,"resource":{"primary":{"URL":"https:\/\/actabio.pwr.edu.pl\/fcp\/xGBUKOQtTKlQhbx08SlkTUARAUWRuHQwFDBoIVURNWHxSBlhnRlUuWTISTnoYDxMe\/302\/public\/publikacje\/v27-3-2025\/46.pdf"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,8,21]]},"references-count":0,"journal-issue":{"issue":"**3","published-print":{"date-parts":[[2025]]}},"alternative-id":["209529"],"URL":"https:\/\/doi.org\/10.37190\/abb\/209529","relation":{},"ISSN":["1509-409X"],"issn-type":[{"value":"1509-409X","type":"print"}],"subject":[],"published":{"date-parts":[[2025,8,21]]}}}
