To understand how long the benefits acquired from an exercise program can be maintained, the present study evaluated the detraining effects of a 4\u2013week exercise cessation period in older adults who performed combined training at various weekly frequencies for 12 weeks. Methods: This randomized controlled trial assigned participants to one of two training programs: a combined training program twice a week (CT2) or four times a week (CT4) over a period of 12 weeks, followed by a four\u2013week detraining period. The resistance training consisted of six bodyweight exercises, while the aerobic training involved either walking or running. Both the CT2 and CT4 groups completed the same total training volume and overload each week; the only difference was the number of training sessions per week. Assessments were conducted at baseline, after the training period, and after the detraining period, and included the 30\u2013s and five\u2013repetition chair\u2013stand tests, isometric handgrip strength, body mass index (BMI), waist circumference, and waist\u2013to\u2013height ratio. Results: Thirty\u2013one participants completed the study (CT2: 17 and CT4: 14). The groups presented similar attendance records during the training period (CT2: 96 \u00b1 18% versus CT4: 94 \u00b1 19%). After the 12\u2013week training period, CT2 and CT4 improved lower limb strength, CT2 improved upper limb strength, and CT4 reduced waist circumference and waist\u2013to\u2013height ratio compared to baseline. After the 4\u2013week detraining period, the lower limb strength remained improved in both groups (CT2: 4 \u00b1 1 repetition; p &lt; 0.001 and CT4: 4 \u00b1 1 repetition; p &lt; 0.001) when compared to the corresponding baseline values. The handgrip strength decreased in CT2 compared to post\u2013training values. And the body composition benefit in CT4 was not sustained after detraining. Conclusions: The effects of 4 weeks of detraining after 12 weeks of training performed two or four times per week are similar on some but not all health-related physical fitness parameters.<\/jats:p>","DOI":"10.3390\/ijerph21111433","type":"journal-article","created":{"date-parts":[[2024,10,29]],"date-time":"2024-10-29T06:29:57Z","timestamp":1730183397000},"page":"1433","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Effects of a 4\u2013Week Detraining Period After 12 Weeks of Combined Training Using Different Weekly Frequencies on Health\u2013Related Physical Fitness in Older Adults"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7387-3190","authenticated-orcid":false,"given":"Lucas Betti","family":"Domingues","sequence":"first","affiliation":[{"name":"Postgraduate Program in Cardiology, School of Medicine, Universidade Federal do Rio Grande do Sul, Porto Alegre 90035-903, RS, Brazil"},{"name":"Sports and Exercise Training Study Group, Clinical Research Center, Hospital de Cl\u00ednicas de Porto Alegre, Porto Alegre 90470-260, RS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vin\u00edcius Mallmann","family":"Schneider","sequence":"additional","affiliation":[{"name":"Postgraduate Program in Cardiology, School of Medicine, Universidade Federal do Rio Grande do Sul, Porto Alegre 90035-903, RS, Brazil"},{"name":"Sports and Exercise Training Study Group, Clinical Research Center, Hospital de Cl\u00ednicas de Porto Alegre, Porto Alegre 90470-260, RS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6776-3430","authenticated-orcid":false,"given":"Rodrigo Flores de","family":"Abreu","sequence":"additional","affiliation":[{"name":"Postgraduate Program in Cardiology, School of Medicine, Universidade Federal do Rio Grande do Sul, Porto Alegre 90035-903, RS, Brazil"},{"name":"Sports and Exercise Training Study Group, Clinical Research Center, Hospital de Cl\u00ednicas de Porto Alegre, Porto Alegre 90470-260, RS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1886-2517","authenticated-orcid":false,"given":"Leandro de Oliveira","family":"Carpes","sequence":"additional","affiliation":[{"name":"Postgraduate Program in Cardiology, School of Medicine, Universidade Federal do Rio Grande do Sul, Porto Alegre 90035-903, RS, Brazil"},{"name":"Sports and Exercise Training Study Group, Clinical Research Center, Hospital de Cl\u00ednicas de Porto Alegre, Porto Alegre 90470-260, RS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1043-821X","authenticated-orcid":false,"given":"Rodrigo","family":"Ferrari","sequence":"additional","affiliation":[{"name":"Postgraduate Program in Cardiology, School of Medicine, Universidade Federal do Rio Grande do Sul, Porto Alegre 90035-903, RS, Brazil"},{"name":"Sports and Exercise Training Study Group, Clinical Research Center, Hospital de Cl\u00ednicas de Porto Alegre, Porto Alegre 90470-260, RS, Brazil"},{"name":"Postgraduate Program in Human Movement Sciences, School of Physical Education, Universidade Federal do Rio Grande do Sul, Porto Alegre 90040-060, RS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"689","DOI":"10.1055\/s-0030-1261895","article-title":"Physiological Effects of Concurrent Training in Elderly Men","volume":"31","author":"Cadore","year":"2010","journal-title":"Int.
