Aims: The present study sought to analyze the effects of 6-month multicomponent training (MCT) combined with a 4-month detraining on metabolic syndrome (MetS) profile among older adults with decreased functional capacity., Methods: This quasi-experimental study included a total of 104 older adults (80.5 ± 6.0 years) and the sample was divided into a training (TRAIN, n = 55) or control group (CON). Harmonized definition was used to diagnose the MetS. Functional capacity, blood biochemical parameters, blood pressure, body composition and anthropometric measurements were assessed 3 times. Analysis of variance for repeated measures and Wilcoxon signed-rank test were used to check the differences within groups., Results: TRAIN decreased diastolic blood pressure (DBP), high-density lipoprotein cholesterol (HDLC) and total fat mass during training period, whereas CON did not show any significant changes. During detraining, TRAIN increased HDLC, systolic blood pressure (SBP), waist circumference (WC) and total fat mass; and decreased glucose and fat free mass, whereas CON increased the concentration of glucose and HDLC. From baseline to post-detraining assessment, CON increased the concentration of triglycerides and the WC, while TRAIN only increased the WC (all p < 0.05)., Conclusions: Exercise can be a key component in the treatment of the MetS, since MCT seems to be effective to decrease DBP and total fat mass. Nevertheless, 4-months of detraining could cause a drop of total fat mass, but no in DBP. To avoid reversibility of the benefits obtained, it could be beneficial to promote continuing exercise programs., Trial Registration: ClinicalTrial.gov identifier: NCT03831841., Competing Interests: Declaration of competing interest None., (Copyright © 2024 The Authors.

This systematic review was conducted to examine the cost-effectiveness of exercise interventions in community-dwelling older adults. A systematic search for articles published in English or Spanish was carried out in PubMed, Web of Science and Cochrane Library that covered the period from the respective start date of each database to October 2021. Methodological quality was assessed with the Physiotherapy Evidence Database scale and quality of economic evaluation with the Quality of Health Economic Studies and Consolidated Health Economic Evaluation Reporting Standards. A total of 12 out of 15 studies on exercise programmes for older adults reported cost-effective results. The most cost-effective training appears to be a multicomponent training programme, including aerobic exercise, muscle-strengthening of lower extremities, and balance and stretching training. The training methodology should be of progressive moderate or vigorous intensity performed at least twice per week with each session lasting 60 min for ≥6 months. The exercise programme should be delivered as a group-based intervention, doing extra exercise at home to increase the cost-effectiveness. These findings suggest that exercise interventions in non-institutionalized older people are a cost-effective tool. Sex, age, cognitive status, frailty, frequency and training duration could modify the cost-effectiveness of exercise interventions. Systematic review registration.
