The objective of this study was to determine the effects of a high-intensity functional training (HIFT) program on the physical condition and functional capacity of an elderly Colombian population with mild cognitive impairment. This research corresponds to a blind randomized controlled clinical trial. A total of 169 men and women aged over 65 years were evaluated and distributed in two groups: the experimental group that received a 12-week HIFT intervention (n = 82) and the control group (n = 87) that received general recommendations on the benefits of physical exercise. The outcome variables included physical condition, assessed using the Senior Fitness battery (SNB); Fried\u2019s frailty phenotype was applied, and gait and balance were assessed using the Tinetti scale. For the functional variables, activities of daily living, instrumental activities of daily living, and advanced activities of daily living were evaluated. All variables were measured pre- and post-intervention. Statistically significant improvements were observed in the IG for gait stability and balance (p &lt; 0.001), as well as for independence in activities of daily living (p = 0.003), and instrumental and advanced activities (p &lt; 0.001). Likewise, greater functionality was found when assessed with the SNB (p &lt; 0.001), except for upper limb strength. The frailty classification did not show changes post-intervention (p = 0.170) nor in the group x time interaction. MANCOVA analysis showed that regardless of gender, health level, age, BMI, cognition, and health level, the HIFT intervention produced better results in functional capacity, balance, and gait (F = 0.173, p &lt; 0.001, Wilks\u2019 \u03bb = 88.231).<\/jats:p>","DOI":"10.3390\/life13051224","type":"journal-article","created":{"date-parts":[[2023,5,22]],"date-time":"2023-05-22T01:31:46Z","timestamp":1684719106000},"page":"1224","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Effects of High-Intensity Functional Training (HIFT) on the Functional Capacity, Frailty, and Physical Condition of Older Adults with Mild Cognitive Impairment: A Blind Randomized Controlled Clinical Trial"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6964-5304","authenticated-orcid":false,"given":"Yulieth","family":"Rivas-Campo","sequence":"first","affiliation":[{"name":"Faculty of Human and Social Sciences, University of San Buenaventura-Cali, Santiago de Cali 760016, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9386-9199","authenticated-orcid":false,"given":"Agust\u00edn","family":"Aibar-Almaz\u00e1n","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Faculty of Health Sciences, University of Ja\u00e9n, 23071 Ja\u00e9n, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7958-0751","authenticated-orcid":false,"given":"Diego Fernando","family":"Afanador-Restrepo","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences and Sport, University Foundation of the \u00c1rea Andina\u2013Pereira, Pereira 660004, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patricia Alexandra","family":"Garc\u00eda-Garro","sequence":"additional","affiliation":[{"name":"Faculty of Distance and Virtual Education, Antonio Jos\u00e9 Camacho University Institution, Santiago de Cali 760016, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gloria Cecilia","family":"Vega-\u00c1vila","sequence":"additional","affiliation":[{"name":"Faculty of Distance and Virtual Education, Antonio Jos\u00e9 Camacho University Institution, Santiago de Cali 760016, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos","family":"Rodr\u00edguez-L\u00f3pez","sequence":"additional","affiliation":[{"name":"Lecturer University Schools Gimbernat, University of Cantabria, 39005 Santander, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6233-6787","authenticated-orcid":false,"given":"Yolanda","family":"Castellote-Caballero","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Faculty of Health Sciences, University of Ja\u00e9n, 23071 Ja\u00e9n, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda del Carmen","family":"Carcel\u00e9n-Fraile","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Faculty of Health Sciences, University of Ja\u00e9n, 23071 Ja\u00e9n, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1295-1968","authenticated-orcid":false,"given":"Mar\u00eda Leyre","family":"Lavilla-Lerma","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Faculty of Health Sciences, University of Ja\u00e9n, 23071 Ja\u00e9n, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,21]]},"reference":[{"key":"ref_1","unstructured":"He, W., Goodkind, D., and Kowal, P.R.
