Resumo Introdução: Estudos têm demonstrado a importância dos hábitos saudáveis em idosos, enfatizando a atividade física ou mobilidade como categoria para uma melhor qualidade de vida nas condições orgânicas e retardo da degeneração física nesse grupo populacional. Dentre diversas atividades físicas, o yoga é conhecido como um dos exercícios indicados e utilizados de forma terapêutica, que pode reduzir o risco de quedas, sendo este um evento prevalente nessa faixa etária. Objetivo: Sintetizar as evidências existentes quanto aos efeitos da prática de yoga na qualidade de vida e capacidade físico-funcional que possam contribuir para a prevenção de quedas em idosos. Métodos: Trata-se de uma revisão sistemática, cujas buscas foram realizadas em agosto de 2020 nas bases de dados Medline/Pubmed, LILACS, SCOPUS, Web of Science e PEDro, sem restrições linguísticas ou de ano de publicação. Seguindo os critérios de elegibilidade, foram incluídos estudos do tipo ensaio clínico randomizado ou quase randomizado. Resultados: Foram encontrados 1190 artigos, sendo incluídos 18 para a coleta dos dados, os quais tinham como amostra uma média de 16 a 120 participantes, sendo esses idosos de 62 a 85 anos e de ambos os sexos. Conclusão: A prática regular de yoga promove benefícios sobre a qualidade de vida e capacidade físico-funcional de idosos que contribuem para a prevenção de quedas. No entanto as evidências ainda são limitadas e sugerem-se novos estudos para melhor elucidação da abrangência dos efeitos do yoga como recurso terapêutico.

Abstract Introduction: Studies have shown the importance of healthy habits in older adults, emphasizing physical activity or mobility for a better quality of life and to delay physical degeneration in this population. Yoga is one of several exercises recommended for therapeutic purposes to reduce the risk of falls, a common occurrence in this age group. Objective: To synthesize the existing evidence regarding the effects of yoga on quality of life and physical-functional capacity and its contribution to fall prevention in older people. Methods: This systematic review was conducted in August 2020 on the Medline/Pubmed, LILACS, SCOPUS, Web of Science and PEDro databases, with no restrictions for language or year of publication. In line with the eligibility criteria, randomized or quasi-randomized clinical trials were included. Results: A total of 1,190 articles were found, 18 of which were included for data collection. The average sample size was between 16 and 120 participants, consisting of older individuals of both sexes ranging in age from 62 to 85 years. Conclusion: Regular yoga practice has a beneficial effect on the quality of life and physical-functional capacity of older adults, thereby contributing to fall prevention. However, evidence is still limited and further studies are suggested to better elucidate the scope of the effects of yoga as a therapeutic resource.

Evidence shows that metabolic syndrome (MS) is associated with a greater risk of developing Parkinson's disease (PD) because of the increase in oxidative stress levels along with other factors such as neuroinflammation and mitochondrial dysfunction. However, because some studies have reported that MS is associated with a lower risk of PD, the relationship between MS and PD should be investigated. This study aimed to investigate the effect of MS on PD. Two authors searched five electronic databases, namely, MEDLINE, PubMed, Scopus, PsycINFO, Web of Science, and Science Direct, for relevant articles between September and October 2020. After screening the title and abstract of all articles, 34 articles were selected for full-text review. Finally, 11 articles meeting the eligibility criteria were included in the study. The quality of articles was critically evaluated using the Joanna Briggs Institute. Overall, we evaluated data from 23,586,349 individuals (including healthy individuals, with MS and PD) aged 30 years or more. In cohort studies, the follow-up period varied between 2 and 30 years. MS contributed considerably to the increase in the incidence of PD. In addition, obesity, a component of MS, alone can increase the probability of developing neurodegenerative diseases. However, despite few studies on MS and PD, changes in cognitive function and more rapid progression of PD disease has been documented in patients with MS using methods commonly used in research.
