Research highlights the benefits of regular traditional multicomponent training in older adults. The potential effect of exergames on perceptive-cognitive and physical function in prefrail older adults is still little explored. The study aimed to compare the effects of two physical exercise training programs (exergaming vs. traditional multicomponent) on perceptive-cognitive and physical functions of prefrail older adults. This study was a randomized controlled trial having 66 prefrail older adults assigned to two groups (exergame group [EG]: n = 32, 70.84 -4.53 years; multicomponent group [MG]: n = 34, 70.76 -5.60 years). Frailty phenotype, fall history, basic and advanced cognition, perceptual, physical (mobility, gait speed, and balance), and muscle (strength and power) functions were evaluated. Intervention was conducted during 12 weeks. The EG and MG performed similar exercise routines involving the main lower limb muscle groups required in daily activities. A mixed model analysis of variance (ANOVA) and effect size (d) revealed that both programs were effective in postponing frailty status, reducing the fear of falling (EG:

The aims of this study were to compare the effects of a multicomponent exercise program provided at a center (CB) versus done part at home and part at a center (H+CB) on frailty status, strength, physical function, and gait of prefrail older women. Twenty-five women were randomly allocated into the CB (n = 14; 69 ± 6 years) and the H+CB (n = 11; 69 ± 7 years) groups. Both groups completed an exercise program including strengthening, balance, and gait exercises. The program was 12 weeks long, done three times per week, for 60 min per session. Frailty, knee and hip muscle strength, spatiotemporal parameters of the usual and maximum speed dual-task gait, and physical function were assessed at baseline and after program completion. The exercise program reversed the prefrail status of most participants independently of the mode of delivery. Strength increased in both groups, but the CB group had more pronounced improvements in gait and physical function. H+CB exercise programs are good options for prefrail older women.

Objetivamos comparar a função muscular e a funcionalidade entre idosas com OA de joelho (GOA=15) e idosas assintomáticas (GAS=18). Foram mensurados dados antropométricos, funcionalidade e qualidade de vida por meio de um questionário específico para OA, Western Ontario and Mc Master Universities Osteoarthritis Index e um conjunto de testes funcionais: Short Physical Performance Battery,TimedUpand Go Teste Teste de Caminhada de 6 minutos. A normalidade dos dados foi verificada pelo teste de Kolmogrov-Smirnov. Para as variáveis com distribuição normal foi aplicado o teste "T" de Student para amostras independentes e o teste não paramétrico "U" Mann-Whitney para os dados que não apresentaram normalidade (p<0,05).Os resultados indicam que não há diferenças entre os grupos nas variáveis antropométricas, na idade e no desempenho físico e funcional. Podemos concluir que idosas com osteoartrite de joelho em grau leve e moderado apresentam desempenho físico e funcional semelhante a idosas assintomáticas.

Background Multicomponent physical exercise programs are a viable strategy for treating physical decline resulting from the aging process in older populations and can be applied in supervised and home-based modalities. However, the magnitude of the intervention effects in terms of physical function development may vary according to the modalities application due to different supervision degrees. Objective This study aims to compare the effects of supervision in a multicomponent exercise program in different application modalities (supervised vs. home vs. supervised+home) in neuromuscular adaptations, muscle strength, gait, physical function, and quality of life, analyzing the differences between intensity, volume, and density of home and supervised sessions in community older adults. Methods This protocol is a randomized controlled clinical trial with a sample of 66 older adults divided into three groups: supervised exercise (SUP = 22), home-based exercise (HB = 22), and supervised plus home-based exercise (SUP+HB = 22). The multicomponent exercise program will last 12 weeks, three times per week, for 60 min per session and include warm-up, balance, muscle-strengthening, gait, and flexibility exercises. The study’s primary outcomes will be neuromuscular function, composed of the assessment of muscle isokinetic strength, muscle architecture, and neuromuscular electrical activation. The secondary outcome will be physical function, usual and maximum gait speed with and without dual-task, and quality of life. All outcomes will be assessed at baseline and post-intervention (week 12). Conclusion This study will be the first clinical trial to examine the effects of different supervision levels on home-based exercises compared to supervised protocols. The results of this study will be essentials for planning coherent and viable home-based programs for older adults. Trial registration Brazilian Registry of Clinical Trials.
