Maximal wheelchair linear velocity has previously been observed to be reached after the release of the handrims both during sports activities and daily life propulsion. This paper provides a combined analysis of linear velocity and trunk kinematics in elite wheelchair racing athletes during straight-line propulsion at stabilized speeds. MWC and trunk kinematics of eight athletes (level: 7 elite, 1 intermediate; classification: T54 (5), T53 (2) and T52 (1)) were monitored during 400 m races using inertial measurement units. An average propulsion cycle was computed for each athlete. The main finding of this article is the difference in propulsion patterns among the athletes, exhibiting either 1, 2 or 3 peaks in their velocity profile. A second peak in velocity is usually assumed to be caused by the inertia of the trunk. However, the presence of a second velocity peak among more severely impaired athletes with little to no trunk motion can either be associated to the inertia of the athletes\u2019 arms or to their propulsion technique.<\/jats:p>","DOI":"10.3390\/s23010058","type":"journal-article","created":{"date-parts":[[2022,12,22]],"date-time":"2022-12-22T02:31:11Z","timestamp":1671676271000},"page":"58","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Analyzing Intra-Cycle Velocity Profile and Trunk Inclination during Wheelchair Racing Propulsion"],"prefix":"10.3390","volume":"23","author":[{"given":"Yoann","family":"Poulet","sequence":"first","affiliation":[{"name":"Centre d\u2019\u00c9tudes et de Recherche sur l\u2019Appareillage des Handicap\u00e9s, Institution Nationale des Invalides, 75007 Paris, France"},{"name":"Arts et M\u00e9tiers Institute of Technology, Universit\u00e9 Sorbonne Paris Nord, IBHGC\u2014Institut de Biom\u00e9canique Humaine Georges Charpak, HESAM Universit\u00e9, 151 Bd de l\u2019H\u00f4pital, 75013 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8512-9879","authenticated-orcid":false,"given":"Florian","family":"Brassart","sequence":"additional","affiliation":[{"name":"Laboratoire IAPS, Universit\u00e9 de Toulon, 83130 Toulon, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emeline","family":"Simonetti","sequence":"additional","affiliation":[{"name":"Centre d\u2019\u00c9tudes et de Recherche sur l\u2019Appareillage des Handicap\u00e9s, Institution Nationale des Invalides, 75007 Paris, France"},{"name":"Arts et M\u00e9tiers Institute of Technology, Universit\u00e9 Sorbonne Paris Nord, IBHGC\u2014Institut de Biom\u00e9canique Humaine Georges Charpak, HESAM Universit\u00e9, 151 Bd de l\u2019H\u00f4pital, 75013 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H\u00e9l\u00e8ne","family":"Pillet","sequence":"additional","affiliation":[{"name":"Arts et M\u00e9tiers Institute of Technology, Universit\u00e9 Sorbonne Paris Nord, IBHGC\u2014Institut de Biom\u00e9canique Humaine Georges Charpak, HESAM Universit\u00e9, 151 Bd de l\u2019H\u00f4pital, 75013 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9399-6366","authenticated-orcid":false,"given":"Arnaud","family":"Faupin","sequence":"additional","affiliation":[{"name":"Laboratoire IAPS, Universit\u00e9 de Toulon, 83130 Toulon, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6196-2698","authenticated-orcid":false,"given":"Christophe","family":"Sauret","sequence":"additional","affiliation":[{"name":"Centre d\u2019\u00c9tudes et de Recherche sur l\u2019Appareillage des Handicap\u00e9s, Institution Nationale des Invalides, 75007 Paris, France"},{"name":"Arts et M\u00e9tiers Institute of Technology, Universit\u00e9 Sorbonne Paris Nord, IBHGC\u2014Institut de Biom\u00e9canique Humaine Georges Charpak, HESAM Universit\u00e9, 151 Bd de l\u2019H\u00f4pital, 75013 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,21]]},"reference":[{"key":"ref_1","first-page":"141","article-title":"Expert Users\u2019 Perceptions of Racing Wheelchair Design and Setup: The Knowns, Unknowns, and next Steps","volume":"34","author":"Bundon","year":"2017","journal-title":"Adapt.
