This scoping review was conducted in accordance with the PRISMA statement. Articles were searched in MEDLINE by PubMed, ELSEVIERby SCOPUS and SciELO. The MeSH terms «Exercise», Exercise Therapy» and «Aged» were used between 2015 and 2020. We searched for articles inSpanish, English, and Portuguese carried out in people aged 65 years and over.101 out of 4,642 randomized controlled trials (RCT) were included. A totalsample of 5,013 older adults (79% women), with an average age of 68.2 years started their studies and 4,312 finished it, presenting an adherence to theinterventions of 86%. Most of the studies were carried out in healthy older adults, in places enabled for the practice of physical activity, in charge of aphysical activity professional, and the interventions were performed carried out through group therapeutic exercise. No article reported information onthe minimum time of participation to the session to be considered as carried out. Only 30% of the articles reported the minimum participation of olderadults in the intervention to include them in the study analysis, and 21% reported the average number of sessions attended to the intervention. The mainreasons for abandonment were personal causes unrelated to the intervention. Only 5% of the articles reported injury of one of the participants (in twoof them the injury was related to the intervention applied). This review characterized the physical exercise programs in older adults in Latin America, aswell the adherence characteristics and the main reasons for abandonment to physical exercise-based interventions, by summarizing available evidencederived from RCTs.
