“…Sabe-se que a disfunção da mobilidade em idosos geralmente está associada a uma combinação de fatores relacionados à idade, como declínio da massa muscular e redução da acuidade sensório-motora, que são fatores de risco para perda de autonomia durante as atividades de vida diária. [20][21][22][23] Também é conhecido que o tempo de execução do TUG está correlacionado à limitação nas AIVDs e ao risco de quedas 4 e que a força do joelho, o número de condições médicas, a idade, a função cognitiva e o estado de saúde são preditores independentes do desempenho do TUG. 24,25 Portanto, embora o avançar da idade tenha repercussões negativas na força e na mobilidade muscular, a manutenção de bons níveis de força em mulheres idosas prediz boa mobilidade funcional para enfrentar as dificuldades impostas pela idade.…”

To analyze the association between functional mobility and anthropometric and functional characteristics of older women after 12 weeks of resistance training. METHODS: Forty-seven community-dwelling older women underwent 12 weeks of supervised resistance training twice a week. The dependent variable (mobility measured by the Timed Up and Go test) and the independent variables (age, body mass index, fat-free mass of the lower limbs, waist circumference, peak knee torque at 60º/s, peak knee torque at 180º/s, functional reach test, and 30-second chair stand test) were measured before and after the intervention. RESULTS: A multivariate analysis showed that age, body mass index, waist circumference, and the 30-second stand test predicted 30% (R2 = 0.30; p = 0.001; F = 5.53) of the total variance regarding an improvement in mobility after resistance training (p < 0.0001; [95% CI 0.72–1.20]; the effect size was considered large [0.90]) when comparing women before and after the intervention. CONCLUSIONS: Age, body mass index, waist circumference, and the 30-second stand test predicted 30% of the increase in functional mobility.

Background: Home-based video exercise programmes might be a suitable alternative to traditional physi¬cal activity in older adults to preserve muscle health. The aim of this systematic review and meta-analysis was to examine the effects of home-based video exercise programmes on physical fitness in older adults. Methods: A systematic review and robust variance estimation meta-analysis with meta-regression were carried out according to the recommendations and criteria outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Results: Thirteen studies involving 1,056 participants were included. Meta-analysis showed statistically significant positive changes in balance (p = 0.023), upper extremity strength (p = 0.049, and strength overall (p = 0.042), there was also statistically significant positive effect based on all the 28 outcomes in eight studies, including 696 participants (p = 0.008). Conclusion: The present systematic review and meta-analysis indicate that home-based video exercise programmes positively affect essential components of physical fitness, such as balance and strength, to prevent falls in older adults. Promoting home-based video exercise in clinical practice and ideally sup¬porting it through supervision is vital to effectively combat the age-related physical decline, especially for those in home isolation.

The epidemiological demands of aging point to the need for characterizing older adults regarding health and disability. This systematic review aims to summarize the indicators (instruments) identifying different components of disability as a result of aging exposition in community-dwelling older adults, considering the International Classification of Functioning, Disability, and Health framework. Taking the PRISMA 2020 recommendations as a reference, studies with community-dwelling older adults, reporting the development and/or age disability modifications were included. Two reviewers analyzed the observational studies searched in the MEDLINE, CINAHL, Web of Science, Scopus, and Embase databases. Of the 137 potentially eligible studies, 49 were included in this review. Several indicators (instruments) demonstrated older adults’ disabilities according to the different domains of the ICF. Objective measures assessed Body Structures, Body Functions, and Environmental Factors and included handgrip strength (dynamometry, n = 8), cognitive function (Mini-Mental State examination, n = 7), gait speed (walk test, n = 6), and endurance (Chair stand-test, n = 4). Self-reported measures assessed Activities and Participation, but not the Body Structures, and included the basic and instrumental activities of daily living (ADL) (the Katz Index of ADL, n = 4 studies, the Lawton and Brody Instrumental ADL, n = 4 studies). The summary of the measures gathered can guide researchers and health professionals to select indicators (instruments) to assess and monitor older adults’ disabilities resulting from aging exposition, to support the development of new wearables, and to provide improvements to the existing ones, allowing the tailored assessment of different health and disability dimensions.
