Effects of Whole-Body Vibration on Functional Mobility, Balance, Gait Strength, and Quality of Life in Institutionalized Older People: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

The aim of this study was to quantify the effect of whole-body vibration on balance, functional mobility, gait, functional performance, and quality of life in institutionalized older people. Eight databases were systematically reviewed, as recommended by the Cochrane Collaboration. This systematic review was designed to answer the acronym set by the participants, interventions, comparators, and outcomes (PICO)-model. Ten randomized controlled trials were included in the meta-analysis. The analysis of the mean differences (MDs) of the functional mobility assessed with Time Up and Go test was MD = -2.49 s (95% confidence interval, CI, [-4.37, -0.61]; I2 = 68%). In 279 participants from five studies, the overall MD = 0.49 (95% CI [-0.13, 1.11]; I2 = 23%) for gait, and MD = 0.96 (95% CI [-0.45, 2.37]; I2 = 85%) for balance, which represents the total Tinetti score, MD = 1.59 (95% CI [-0.52, 3.70]; I2 = 82%). In summary, whole-body vibration could have benefits on functional mobility in institutionalized older people.

Exercise to treat psychopathology and other clinical outcomes in schizophrenia: A systematic review and meta-analysis.

BACKGROUND: Psychopathology and side effects of antipsychotic drugs contribute to worsening physical health and long-term disability, and increasing the risk of mortality in these patients. The efficacy of exercise on these factors is not fully understood, and this lack of knowledge may hamper the routine application of physical activity as part of the clinical care of schizophrenia. AIMS: To determine the effect of exercise on psychopathology and other clinical markers in patients with schizophrenia. We also looked at several moderators. METHOD: MEDLINE, Web of Science, Scopus, CINAHL, SPORTDiscus, PsycINFO, and Cochrane Library databases were systematically searched from inception to October 2022. Randomized controlled trials of exercise interventions in patients 18-65 years old diagnosed with schizophrenia disorder were included. A multilevel random-effects meta-analysis was conducted to pool the data. Heterogeneity at each level of the meta-analysis was estimated via Cochran's Q, I2, and R2. RESULTS: Pooled effect estimates from 28 included studies (1,460 patients) showed that exercise is effective to improve schizophrenia psychopathology (Hedges' g = 0.28, [95% CI 0.14, 0.42]). Exercise presented stronger effects in outpatients than inpatients. We also found exercise is effective to improve muscle strength and self-reported disability. CONCLUSIONS: Our meta-analysis demonstrated that exercise could be an important part in the management and treatment of schizophrenia. Considering the current evidence, aerobic and high-intensity interval training exercises may provide superior benefits over other modalities. However, more studies are warranted to determine the optimal type and dose of exercise to improve clinical outcomes in people with schizophrenia.

Optimal dose and type of exercise to improve cognitive function in older adults: A systematic review and bayesian model-based network meta-analysis of RCTs.

OBJECTIVE: To examine the dose-response relationship between overall and specific types of exercise with cognitive function in older adults. DESIGN: Systematic Review and Bayesian Model-Based Network Meta-Analysis. DATA SOURCES: Systematic search of MEDLINE, Web of Science, Scopus, PsycINFO and SPORTDiscus. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Randomized controlled trials of exercise interventions in participants aged 50 years or over, and that reported on at least one global cognition outcome. RESULTS: The search returned 1998 records, of which 44 studies (4793 participants; 102 different effect sizes) were included in this review with meta-analysis. There was a non-linear, dose-response association between overall exercise and cognition. We found no minimal threshold for the beneficial effect of exercise on cognition. The estimated minimal exercise dose associated with clinically relevant changes in cognition was 724 METs-min per week, and doses beyond 1200 METs-min per week provided less clear benefits. We also found that the dose-response association was exercise type dependent, and our results show that clinically important effects may occur at lower doses for many types of exercise. Our findings also highlighted the superior effects of resistance exercises over other modalities. CONCLUSIONS: If provided with the most potent modalities, older adults can get clinical meaningful benefits with lower doses than the WHO guidelines. Findings support the WHO recommendations to emphasise resistance training as a critical component of interventions for older adults.

Influência do nível de atividade física sobre a aptidão física e qualidade de vida relacionada à saúde em idosos portadores ou não de diabetes mellitus tipo 2 / Influence of physical activity level on physical fitness and health-related quality of life in elderly with and without type 2 diabetes mellitus / Influencia del nivel de actividades físicas sobre la aptitud física y la calidad de vida, vinculada a la salud, en ancianos portadores o no de diabetes mellitus tipo 2

INTRODUÇÃO: O exercício físico é considerado um dos componentes para melhoria das condições de saúde em diabéticos tipo 2. Além disso, alguns estudos têm sugerido que níveis mais elevados de aptidão física também podem melhorar a qualidade de vida relacionada à saúde (QVRS). No entanto, não existem estudos publicados que sejam especificamente concebidos para examinar esta relação. OBJETIVO: O objetivo do presente estudo foi avaliar o efeito do nível de atividade física sobre a aptidão física e QVRS e determinar se existem diferenças quando indivíduos com e sem diabetes mellitus tipo 2 são comparados. MÉTODO: Cinquenta e quatro participantes com diabetes tipo 2 e 54 participantes pareados por idade sem diabetes foram voluntários para participar deste estudo. A aptidão física (teste de levantar da cadeira de 30 segundos, teste de caminhada de seis minutos e teste de sentar e alcançar) e QVRS (VC-36) foram avaliadas. RESULTADOS: Os participantes com diabetes tipo 2 apresentaram menores escores médios para o teste de sentar e alcançar e uma maior pontuação em relação ao escore do componente mental do que os controles. Quando os dois grupos foram classificados quanto ao nível de atividade física, foram encontradas diferenças significativas em relação a função social, saúde mental, saúde geral e vitalidade, entre os pacientes insuficiente e minimamente ativos. CONCLUSÃO: Os participantes com maiores níveis de prática de atividade física também relataram melhor aptidão física, a qual, juntamente com as melhorias na QVRS, pode ter implicações clínicas na prevenção e tratamento do diabetes mellitus tipo 2.

INTRODUCTION: Physical exercise is considered to improve different health outcomes in type 2 diabetic patients. In addition, a few studies have suggested that higher levels of fitness might also enhance health-related quality of life (HRQoL). However, there are no published studies that were specifically designed to examine this relationship. OBJECTIVE: The aim of the current study was to assess the effect of physical activity level on physical fitness and HRQoL and determine whether differences existed when comparing people with and without type 2 diabetes mellitus. METHODS: Fifty-four participants with type 2 diabetes and 54 age-matched participants without diabetes volunteered to participate in this study. Physical fitness (30-second chair stand test, six-min walk test and sit-and-reach test) and HRQoL (36-item Short Form Health Survey) were assessed. RESULTS: Participants with type 2 diabetes had lower mean scores for sit and reach and higher mental component score than control participants. When both groups were categorized regarding their level of physical activity significant differences were found in relation to social function, mental health, general health and vitality between poorly and minimally active patients. CONCLUSIONS: Participants with the greater levels of physical activity also reported better physical fitness which together with the improvement in HRQoL may have clinical implications in the prevention and treatment of type 2 diabetes mellitus.

INTRODUCCIÓN: Los ejercicios físicos son considerados como siendo uno de los componentes para la mejoría de las condiciones de salud en diabéticos tipo 2. Además de eso, algunos estudios han sugerido que niveles más altos de aptitud física también pueden mejorar la calidad de vida relacionada con la salud (CVRS). No obstante, no hay estudios publicados que hayan sido planeados, específicamente, para examinar esta relación. OBJETIVO: El objetivo de este estudio fue evaluar el efecto del nivel de actividades físicas sobre la aptitud física y la CVRS, y determinar si hay diferencias cuando se comparan individuos con y sin diabetes mellitus tipo 2. MÉTODO: Cincuenta y cuatro participantes, con diabetes tipo 2, y 54 participantes, de edades comparables, sin diabetes, fueron voluntarios a fin de participar en este estudio. La aptitud física (prueba de 30 segundos para levantarse de la silla, prueba de caminata de seis minutos y prueba de sentarse y alcanzar algo) y la CVRS (VC-36) fueron evaluadas. RESULTADOS: Los participantes con diabetes tipo 2 presentaron menores puntuaciones en promedio para la prueba de sentarse y alcanzar algo, y una puntuación más alta en componente mental en comparación con los participantes de control. Cuando los dos grupos fueron clasificados con respecto al nivel de actividades físicas, se encontraron diferencias significativas con referencia a función social, salud mental, salud general y vitalidad, entre los pacientes insuficiente y mínimamente activos. CONCLUSIÓN: Los participantes con niveles más altos de prácticas de actividades físicas también mostraron mejor aptitud física, la cual, conjuntamente con las mejorías en la CVRS, puede tener implicaciones clínicas para la prevención y el tratamiento de la diabetes mellitus tipo 2.
