This study examined the feasibility and physiological (heart rate, blood pressure, blood lactate, and rate of perceived exertion) and psychological (enjoyment) response resulting from an acute progressive sled-push (SLP) exercise session using the novel XPO Sled Trainer in older adults and compared that with walking (WKC) condition. The exercise session comprised six exercise bouts at 75%, 85%, 100% (2\u00d7), and 125% (2\u00d7) of normal velocity with a 2-min rest between bouts. Thirty-six older adults were randomly allocated into either the SLP or WKC conditions. No adverse events were observed during the exercise session, and all participants completed the exercise protocol as prescribed. One-third of the participants in the SLP group reported minimal body discomfort. Significantly higher responses were observed for all physiological variables as the intensity of the exercise increased in the SLP group compared with the WKC group (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001). The SLP group presented a decline in enjoyment as the intensity of the exercise increased (during), but similar enjoyment level than the WKC group for the overall exercise session (<jats:italic>p<\/jats:italic>\u2009=\u2009.711). Our findings support the viability and safety of SLP exercise using the XPO Sled Trainer in older adults. Such exercise demonstrated an intensity-driven modality that may have potential to elucidate positive adaptations in the cardiovascular system of older adults with acceptable levels of enjoyment.<\/jats:p>","DOI":"10.1123\/japa.2023-0071","type":"journal-article","created":{"date-parts":[[2024,2,10]],"date-time":"2024-02-10T18:05:44Z","timestamp":1707588344000},"page":"416-427","source":"Crossref","is-referenced-by-count":0,"title":["An Investigation of the Sled-Push Exercise Using a Resisted Sled Machine in Apparently Healthy Older Adults: An Exploratory Study"],"prefix":"10.1123","volume":"32","author":[{"given":"Micheal","family":"Baumann","sequence":"first","affiliation":[{"name":"Department of Kinesiology and Physical Education, Northern Illinois University, DeKalb, IL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0043-8753","authenticated-orcid":true,"given":"Christopher","family":"Hill","sequence":"additional","affiliation":[{"name":"Department of Kinesiology and Physical Education, Northern Illinois University, DeKalb, IL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Clayton","family":"Camic","sequence":"additional","affiliation":[{"name":"Department of Kinesiology and Physical Education, Northern Illinois University, DeKalb, IL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Chomentowski","sequence":"additional","affiliation":[{"name":"Department of Kinesiology and Physical Education, Northern Illinois University, DeKalb, IL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1806-1584","authenticated-orcid":true,"given":"Vitor","family":"Siqueira","sequence":"additional","affiliation":[{"name":"Department of Kinesiology and Physical Education, Northern Illinois University, DeKalb, IL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7102-4163","authenticated-orcid":true,"given":"Steven","family":"Petruzzello","sequence":"additional","affiliation":[{"name":"Department of Kinesiology and Community, University of Illinois at Urbana-Champaign, Urbana, IL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6320-7784","authenticated-orcid":true,"given":"Emerson","family":"Sebasti\u00e3o","sequence":"additional","affiliation":[{"name":"Department of Kinesiology and Physical Education, Northern Illinois University, DeKalb, IL, USA"},{"name":"Department of Kinesiology and Community, University of Illinois at Urbana-Champaign, Urbana, IL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","reference":[{"issue":"10","key":"r1","series-title":"Archives of Surgery,","doi-asserted-by":"publisher","first-page":"1068","DOI":"10.1001\/archsurg.138.10.1068","article-title":"Physiological features of aging persons","volume":"138","author":"Aalami, O.O.","year":"2003","unstructured":"Aalami, O.O., Fang, T.D., Song, H.M., & Nacamuli, R.P.
