To address this, this study aimed to investigate movement variability and stability in moderate, heavy, and severe intensity domains, and to examine how these dynamics evolve over time. Twenty\u2010one male runners performed treadmill trials at speeds corresponding to these domains, with lower limb joint angles and centre of mass displacement recorded using 3D motion analysis and analysed at the start, middle, and end of each trial. Non\u2010linear dynamics of joint angles and centre of mass displacement including local dynamic stability, dimensionality, and variability were assessed using Lyapunov exponent (LyE), correlation dimension (CoD), and MeanSD, respectively. Repeated\u2010measures ANOVAs revealed a significant effect of intensity across most parameters, including CoD and LyE at the ankle, knee, and hip (all\n                    <jats:italic>p<\/jats:italic>\n                    \u00a0&lt;\u00a00.05), as well as MeanSD at the hip (\n                    <jats:italic>p<\/jats:italic>\n                    \u00a0&lt;\u00a00.05). Furthermore, a significant effect of intensity was observed in 6 out of the 9 parameters measured at the centre of mass. Effects of time were sparse,\u00a0with interaction effects largely confined to centre of mass variability. Post hoc analyses indicated that higher intensity domains were associated with reduced local dynamic stability, lower dimensionality, and increased variability at some sites. Changes over time were not exclusive to the severe intensity domain, suggesting that metabolic stress does not play an exclusive role in regulating movement dynamics during running. Collectively, these findings suggest that between\u2010domain differences in gait dynamics were more consistent with speed\u2010related task constraints than with cumulative fatigue or metabolic stress alone.\n                  <\/jats:p>","DOI":"10.1002\/ejsc.70236","type":"journal-article","created":{"date-parts":[[2026,8,13]],"date-time":"2026-08-13T19:09:15Z","timestamp":1786648155000},"source":"Crossref","is-referenced-by-count":0,"title":["Movement Dynamics of Treadmill Running Within the Different Exercise Intensity Domains in Male Runners"],"prefix":"10.1002","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4190-4543","authenticated-orcid":false,"given":"Ben","family":"Hunter","sequence":"first","affiliation":[{"name":"School of Human Sciences London Metropolitan University  London UK"},{"name":"School of Health Medicine and Life Sciences University of Hertfordshire  Hatfield UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7336-9472","authenticated-orcid":false,"given":"Bettina","family":"Karsten","sequence":"additional","affiliation":[{"name":"CBS University of Applied Sciences Faculty of Health &amp; Education  Cologne Germany"},{"name":"Institute of Lifecourse Development, Centre for Exercise Activity and Rehabilitation University of London, University of Greenwich  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3407-561X","authenticated-orcid":false,"given":"Mark","family":"Burnley","sequence":"additional","affiliation":[{"name":"School of Sport Exercise and Health Sciences Loughborough University  Loughborough UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Greenhalgh","sequence":"additional","affiliation":[{"name":"School of Health Medicine and Life Sciences University of Hertfordshire  Hatfield UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6748-9870","authenticated-orcid":false,"given":"Daniel","family":"Muniz\u2010Pumares","sequence":"additional","affiliation":[{"name":"School of Health Medicine and Life Sciences University of Hertfordshire  Hatfield UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,13]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1103\/RevModPhys.65.1331"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/J.HUMOV.2019.05.025"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.3389\/fphys.2021.646042"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0021\u20109290(99)00133\u20105"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/J.1748\u20101716.1995.TB09943.X"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/0021\u20109290(90)90054\u20107"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/J.2517\u20106161.1995.TB02031.X"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1152\/japplphysiol.00942.2016"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/apha.13533"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1098\/rsif.2012.0999"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1152\/japplphysiol.00475.2006"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1080\/17461390701456148"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00421\u2010001\u20100556\u20102"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2009.04.012"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.4324\/9780203771587"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1063\/1.1324008"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1115\/1.1336798"},{"key":"e_1_2_9_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2004.12.014"},{"key":"e_1_2_9_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gaitpost.2006.03.003"},{"key":"e_1_2_9_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/J.JSAMS.2010.03.006"},{"key":"e_1_2_9_22_1","doi-asserted-by":"publisher","DOI":"10.1123\/ijspp.2015\u20100618"},{"key":"e_1_2_9_23_1","doi-asserted-by":"publisher","DOI":"10.1016\/0167\u20102789(83)90298\u20101"},{"key":"e_1_2_9_24_1","volume-title":"A Mathematical Model of the Human body(AMRL\u2010TR\u201064\u2010102).
