Acesso em: 01 ago. 2023.2045-2322http://www.repositorio.ufop.br/jspui/handle/123456789/17905To test whether heart rate variability (HRV) biofeedback training benefts older adults with diferent social interaction levels. Methods. 32 older adults (16 were institutionalized and 16 were not). Both groups received 14 sessions, 15 min, 3 times a week, with half of the individuals receiving HRV biofeedback training and the other half receiving control training. The following parameters were assessed immediately before and after training, and 4.5 weeks after the last session (follow-up period): aerobic conditioning, anthropometric data, emotional scores, and HRV components. Results. Before the training, the institutionalized individuals had higher scores of loneliness (p< 0.01) and depression (p< 0.0001) and lower social touches (p< 0.0001), body mass (p= 0.04), and body fat percentage (p= 0.002) than the non-institutionalized individuals. HRV biofeedback improved symptoms of depression in both groups. HRV improved only in the non-institutionalized group, and loneliness only in the institutionalized group. Lastly, all changes persisted after the follow-up period. Conclusions. HRV biofeedback training was efective in improving symptoms of depression in older adults. Improvement of HRV and loneliness was dependent on the level of social interaction.en-USabertoArtigo publicado em periodicoTis article is licensed under a Creative Commons Attribution 4.0 International License, which permits use, sharing, adaptation, distribution and reproduction in any medium or format, as long as you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons licence, and indicate if changes were made.
