It has profound negative effects on overall health and quality of life, including reduced independence, mobility, and daily activity performance, osteoporosis, increased fall and fracture risks, metabolic issues, and chronic diseases like diabetes and cardiovascular conditions. Preventive strategies typically involve a combination of proper nutrition and regular physical activity. Among strength training exercises, high-intensity interval training (HIIT) stands out as the most effective approach for improving muscle function in older adults with sarcopenia. The current review identifies and summarizes the studies that have examined the effects of HIIT on muscle strength in older adults as an element of the prevention and treatment of sarcopenia. A systematic search using several computerized databases, namely, MEDLINE\/PubMed, Scopus, SPORTDiscus, and Web of Science, was performed on 12 January 2023, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 224 studies were initially retrieved. A total of five studies met the selection criteria. HIIT training shows improvements in body composition and functional and cardiorespiratory capacity, has benefits on muscle strength, increases muscle quality and architecture, and is associated with muscle hypertrophy in healthy older adults. Nonetheless, given the shortcomings affecting primary research in terms of the limited number of studies and the high risk of bias, further research is warranted.<\/jats:p>","DOI":"10.3390\/jcm13051299","type":"journal-article","created":{"date-parts":[[2024,2,26]],"date-time":"2024-02-26T03:34:04Z","timestamp":1708918444000},"page":"1299","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Effects of High-Intensity Interval Training on Muscle Strength for the Prevention and Treatment of Sarcopenia in Older Adults: A Systematic Review of the Literature"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0288-4394","authenticated-orcid":false,"given":"Jos\u00e9 Alfonso","family":"Morcillo-Losa","sequence":"first","affiliation":[{"name":"Department of Didactics of Corporal Expression, University of Ja\u00e9n, 23071 Ja\u00e9n, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-7629-5676","authenticated-orcid":false,"given":"Maria del Pilar","family":"D\u00edaz-Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Department of Didactics of Corporal Expression, University of Ja\u00e9n, 23071 Ja\u00e9n, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Halil \u0130brahim","family":"Ceylan","sequence":"additional","affiliation":[{"name":"Physical Education and Sports Teaching Department, Kazim Karabekir Faculty of Education, Ataturk University, 25030 Erzurum, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beatriz","family":"Moreno-Vecino","sequence":"additional","affiliation":[{"name":"Department of Physical Activity and Sport Sciences, Centre d\u2019Ensenyament Superior Alberta Gim\u00e9nez CESAG, Pontifical University of Comillas, 07013 Palma, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8409-868X","authenticated-orcid":false,"given":"Nicola Luigi","family":"Bragazzi","sequence":"additional","affiliation":[{"name":"Laboratory for Industrial and Applied Mathematics (LIAM), Department of Mathematics and Statistics, York University, Toronto, ON M3J 1P3, Canada"},{"name":"Human Nutrition Unit (HNU), Department of Food and Drugs, Medical School, University of Parma, 43125 Parma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0250-0717","authenticated-orcid":false,"given":"Juan","family":"P\u00e1rraga Montilla","sequence":"additional","affiliation":[{"name":"Department of Didactics of Corporal Expression, University of Ja\u00e9n, 23071 Ja\u00e9n, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"16","DOI":"10.1093\/ageing\/afy169","article-title":"Sarcopenia: Revised European consensus on definition and diagnosis","volume":"48","author":"Bahat","year":"2019","journal-title":"Age Ageing"},{"key":"ref_2","first-page":"177","article-title":"Clinical definition of sarcopenia","volume":"11","author":"Santilli","year":"2014","journal-title":"Clin.
