Can resistance training improve mental health outcomes in older adults? A systematic review and meta-analysis of randomized controlled trials.

Purpose This systematic review and meta-analysis aimed to analyze the effects of resistance training (RT) and to compare the different RT prescriptions, sample characteristics, and mental health outcomes (depressive and anxiety symptoms) in older adults. Methods All studies that were available on 28th April 2023. For the analysis of intervention effects on depressive and anxiety symptoms, standardized mean differences and standard errors were calculated. Meta-analyses using random-effects models, employing robust variance meta-regression for multilevel data structures, with adjustments for small samples. Results For depressive symptoms, the mean effect was - 0.94 (95 %CI: -1.45 - -0.43, P< 0.01, I2= 93.4 %), and for anxiety symptoms, the mean effect was -1.33 (95 %CI: -2.10 - -0.56, P< 0.01, I2= 92.3 %). The mean effect was -0.51 (95 %CI: -0.67 - -0.35, P< 0.01, I2= 36.7 %) for older adults without mental disorders, and those with mental disorders the mean effect was ES= -2.15 (95 %CI: -3.01 - - 1.29, P< 0.01, I2= 91.5 %). Conclusion RT was able to improve mental health outcomes in individuals with and without mental disorders, and some RT characteristics influenced the effect of RT on mental health.

Resistance Training for Older Women: Do Adaptive Responses Support the ACSM and NSCA Position Stands?

PURPOSE: The optimal intensity of resistance training (RT) to improve muscular, physical performance, and metabolic adaptations still needs to be well established for older adults. Based on current position statements, we compared the effects of two different RT loads on muscular strength, functional performance, skeletal muscle mass, hydration status, and metabolic biomarkers in older women. METHODS: One hundred one older women were randomly allocated to perform a 12-wk whole-body RT program (eight exercises, three sets, three nonconsecutive days a week) into two groups: 8-12 repetitions maximum (RM) and 10-15RM. Muscular strength (1RM tests), physical performance (motor tests), skeletal muscle mass (dual-energy X-ray absorptiometry), hydration status (bioelectrical impedance), and metabolic biomarkers (glucose, total cholesterol, HDL-c, HDL-c, triglycerides, and C-reactive protein) were measured at baseline and posttraining. RESULTS: Regarding muscular strength, 8-12RM promoted higher 1RM increases in chest press (+23.2% vs +10.7%, P < 0.01) and preacher curl (+15.7% vs +7.4%, P < 0.01), but not in leg extension (+14.9% vs +12.3%, P > 0.05). Both groups improved functional performance ( P < 0.05) in gait speed (4.6%-5.6%), 30 s chair stand (4.6%-5.9%), and 6 min walking (6.7%-7.0%) tests, with no between-group differences ( P > 0.05). The 10-15RM group elicited superior improves in the hydration status (total body water, intracellular and extracellular water; P < 0.01), and higher gains of skeletal muscle mass (2.5% vs 6.3%, P < 0.01), upper (3.9% vs 9.0%, P < 0.01) and lower limbs lean soft tissue (2.1% vs 5.4%, P < 0.01). Both groups improved their metabolic profile. However, 10-15RM elicited greater glucose reductions (-0.2% vs -4.9%, P < 0.05) and greater HDL-c increases (-0.2% vs +4.7%, P < 0.01), with no between-group differences for the other metabolic biomarkers ( P > 0.05). CONCLUSIONS: Our results suggest that 8-2RM seems more effective than 10-15RM for increasing upper limbs' muscular strength, whereas the adaptative responses for lower limbs and functional performance appear similar in older women. In contrast, 10-15RM seems more effective for skeletal muscle mass gains, and increased intracellular hydration and improvements in metabolic profile may accompany this adaptation.

Introdução: Políticas públicas intersetoriais em saúde são intervenções populacionais (e de cunho ecológico) muito utilizadas para a redução da carga global de doença e otimização de recursos tanto financeiros quanto humanos. Objetivo: O objetivo deste estudo foi analisar a situação de saúde de usuários idosos de uma política municipal de atividades físicas. Métodos: Trata-se de um estudo transversal com amostragem baseada em centros comunitários (N dispositivos comunitários=11), que disponibilizam práticas de movimentos corporais e outros, subsidiados pela Secretaria Municipal de Desenvolvimento Social e Esporte (SMDSE), Prefeitura Municipal de Porto Alegre (RS). A amostragem de usuários foi ponderada para o total de usuários atendidos por centro, adotando seleção aleatória simples. A coleta de dados ocorreu entre abril de 2018 e fevereiro de 2019, em que a equipe de coleta se deslocou ao território adscrito dos usuários para a condução de inquérito de saúde autoaplicado e a avaliação funcional; de forma contrária, os usuários compareceram a um centro de coleta para a série laboratorial (sem jejum). Resultados: Foram incluídos e analisados 351 usuários (média±desvio padrão, 70±6 anos). Para fatores de risco cardiovasculares, a prevalência de hipercolesterolemia foi de 54,2% e de 49,3% para hipertensão arterial sistêmica ­ as mais elevadas. O transtorno de sono foi prevalente em 55,3% da amostra. Entre as doenças autorrelatadas, os participantes listaram as cardiovasculares (14,3%), câncer prévio (14,6%), diabetes (13,2%), artrite reumatoide/ reumatismo (29,6%) e depressão (sem discriminador de depressão maior/ menor) (18,6%). A capacidade funcional, estimada pelo teste de caminhada em 6 minutos e a força de preensão manual, preditores de mortalidade cardiovascular e agravos, tiveram valores médios encontrados de 498,05±78,96 m e 27,08±8,14 kg, respectivamente. Conclusão: Os achados do presente estudo permitem contrastar prevalências estimadas em idosos participantes de um programa público de atividades físicas com outras estimativas em grupos de comparação, possibilitando a análise de situação de saúde com base em diferentes comportamentos e fatores de risco. Por fim, o trabalho viabilizou a monitorização de intervenções públicas para idosos em nível comunitário, sendo um ponto de base para acompanhamento futuro.

Introduction: Intersectoral public policies on health are population (and ecological) interventions widely used to reduce the global burden of disease and optimize both financial and human resources. Objective: The objective of this study was to analyze the health status of older adults users of a municipal policy on physical activities. Methods: This is a cross-sectional study with a sample based on community centers (N community centers=11), which provide body movement practices and others, funded by the Municipal Department of Social Development and Sports (SMDSE), City Hall of Porto Alegre (state of Rio Grande do Sul ­ RS, Brazil). The users' sample was weighted by the number of users of each center, by simple random sampling. Data collection took place between April 2018 and February 2019, in which the collection team went to the users' assigned territory to conduct a self-administered health survey and functional assessment; conversely, the users attended a collection center for laboratory tests (without fasting). Results: A total of 351 users (mean±SD, 70±6 years old) were included. For cardiovascular risk factors, the prevalence of hypercholesterolemia was 54.2% and 49.3% for systemic arterial hypertension ­ the highest levels. Sleep disorder was prevalent in 55.3% of the sample. Among the self-reported diseases, participants listed cardiovascular (14.3%), previous cancer (14.6%), diabetes (13.2%), rheumatoid arthritis/rheumatism (29.6%), and depression (without major/minor depression discrimination) (18.6%). Functional capacity, estimated by the six-minute walk test, and handgrip strength, predictors of cardiovascular mortality and injuries, had mean values of 498.05±78.96 m and 27.08±8.14 kg, respectively. Conclusions: The findings of this study allow contrasting prevalence rates estimated in older adults participants of a public physical activity program with other estimates in comparison groups, enabling the analysis of health status based on different behaviors and risk factors. All in all, our study enabled to monitor public interventions for older adults at the community level, serving as a baseline for future monitoring.

Body fat estimated by equations based on anthropometric parameters correlates with bioelectrical impedance in patients undergoing bariatric surgery / Gordura corporal estimada por equações baseadas em parâmetros antropométricos correlaciona-se com a bioimpedância elétrica em pacientes submetidos à cirurgia bariátrica

Introduction: predictive equations to estimate body fat based on simple anthropometric parameters are easy to use in the clinical practice.Objective: to evaluate the relationship between predictive equations based on anthropometric parameters and bioelectrical impedance to estimate body fat in individuals undergoing bariatric surgery.Methods: a prospective and longitudinal study carried out with individuals undergoing bariatric surgery. Body weight, body mass index, waist circumference and body fat percentage estimated by anthropometric parameters and by impedance were evaluated at three moments, one month before, two and six months after surgery. Data were analyzed by one-way ANOVA for repeated measures with Holm-Sidak ́s post hoc or Friedman test with Tukey ́s post hoc, and Pearson or Spearman correlations, according to data distribution. Significance level adopted 5%.Results: twenty-five subjects composed the final sample. All anthropometric parameters reduced significantly over time (p<0.001). Except for Lean et al equation before surgery, the body fat percentage estimated by other formulas showed a strong correlation with impedance in all moments, with the highest correlation strength observed in Gómez-Ambrosi et al. equation.Conclusion: in the present study, the equations used showed a good correlation with bioelectrical impedance, and the Gómez-Ambrosi et al. equation as a better option to the use of bioimpedance to assess changes in body fat percentage of patients undergoing bariatric surgery for the treatment of severe obesity.

Introdução: Objetivos: analisar o consumo alimentar e os fatores associados ao estado nutricional de crianças menores de dois anos de vida.Método: Estudo de corte transversal realizado com uma amostra de 344 lactentes menores de dois anos de idade e suas respectivas mães, acompanhadas em Unidades de Saúde da Família. As variáveis sociodemográficas, antropométrica das mães e dos lactentes e o consumo alimentar dessas crianças foram avaliadas por meio de questionário estruturado. A força de associação entre as variáveis dependente e as independentes foi avaliada pelo odds ratio, tanto na análise univariada quanto na múltipla, com nível de significância de 5%.Resultados: A prevalência do estado nutricional inadequado foi de 38,08%. Observou que 29,09% das crianças menores de seis meses de idade não chegaram a receber leite materno de forma exclusiva ou o tempo de oferta foi inferior a 30 dias. Notou-se o consumo de alimentos ultraprocessados, principalmente, do suco industrializado no último mês [OR:1,96, IC 95%: 1,05-3,65], baixa ingestão de frutas e o hábito de comer assistindo televisão nos lactentes maiores de seis meses. Após ajuste para variáveis de confusão, permaneceram associadas ao estado nutricional: anemia gestacional [OR: 3,58 IC: 1,46-8,77] e trabalho materno [OR, 0,38, IC 95%: 0,18-0,80].Conclusão: A presença do estado nutricional inadequado, caracterizado pelo baixo ou excesso de peso, associou-se ao fato de a mãe trabalhar e à anemia gestacional. Ademais, constatou-se a participação precoce de alimentos ultraprocessados na alimentação das crianças menores de 24 meses de idade, substituindo alimentos considerados naturais e saudáveis, evidenciando assim práticas alimentares inadequadas frente às recomendações para a faixa etária.

Atividade física para idosos: Guia de Atividade Física para a População Brasileira / Physical activity for older adults: Physical Activity Guidelines for the Brazilian Population

Por iniciativa do Ministério da Saúde, em colaboração com pesquisadores nacionais, elaborou-se o primeiro Guia de Atividade Física (AF) para a População Brasileira, incluindo recomendações para as várias fases da vida e populações especiais. O objetivo deste estudo é apresentar o processo me-todológico e os resultados do capítulo de recomendações de AF para idosos. O Grupo de Trabalho Idosos (GT Idosos) contou com a participação de 11 pesquisadores/profissionais que realizaram reuniões virtuais semanais, revisão sistemática de revisões, que incluiu 50 artigos ao final, e escutas com profissionais de Educação Física (n = 143), gestores (n = 17) e com idosos (n = 22), de todas as regiões do país, por meio de entrevistas telefônicas e formulários eletrônicos. Baseado nos resultados da revisão e das escutas, elaborou-se uma primeira versão das recomendações de AF para idosos, que foi submetida à consulta pública. No total foram recebidas 46 sugestões válidas, das quais 34 foram aceitas e incorporadas ao texto final por possuírem relevância técnica e/ou social. Como resultados, o Guia destaca os principais benefícios da AF para idosos, como melhora dos aspectos físicos, mentais e sociais, e recomenda um mínimo de 150 minutos por semana de AF de intensidade moderada, ou 75 minutos de intensidade vigorosa, considerando as AF no tempo livre, no deslocamento, no trabalho/estudo ou nas tarefas domésticas. Acredita-se que o Guia auxiliará os idosos e profissionais de saúde a conhecerem os benefícios da AF, a quantidade recomendada e as diversas possibilidades de prática, por meio de mensagens e exemplos culturalmente apropriados

At the Ministry of Health initiative, in collaboration with national researchers, the first Physical Activity (PA) Guidelines for the Brazilian Population was prepared, including recommendations for the various stages of life and special populations. This study aims to present the methodological process of the chapter on PA recommendations for the elderly. The Elderly Work Group had 11 researchers/professionals who held weekly virtual meetings, made a systematic review of reviews, which included 50 articles, and promoted a listening among elderly (n = 22), managers (n = 17) and professionals (n = 143) from all country regions, through telephone interviews and online forms. Based on the review and the listening results, a first version of the PA Guidelines for the elderly was elaborated, which was submitted to public consultation. Forty-six valid suggestions were received for the Guide's writing, of which 34 were accepted and incorporated into the final text since they had technical and/or social relevance. As results, the Guidelines highlight the major benefits of PA for the elderly, such as enhancement of the physical, mental and social aspects, and recommends a minimum of 150 minutes of moderate PA or 75 minutes of vigorous PA per week, considering PA in leisure time, commuting and domestic activities, as well as in work/study time. It is believed that these Guidelines will help the elderly and health professionals to get to know the benefits of PA, the recommended amount, and the different possibilities of practice through culturally appropriate messages and examples. Politically, it will reinforce the central role of PA in the prevention and control of chronic non-communicable diseases, boosting actions for its dissemination and implantation

Health profile of elderly users of a town public program of physical activity: a cross-sectional study / Perfil da situação de saúde dos idosos participantes de um programa municipal de atividades físicas: um estudo transversal

The assessment of health profile in users attending such public programs may optimize tailoring of interventions oriented to reduce the risk or incidence of lifestyle-driven diseases, resulting in a potential impact on public health. Therefore, this cross-sectional study aimed to characterize the health profile of the elderly participants in the physical activity public program in southern Brazil. Therefore, we included 11 community exercise centers managed by the city of Porto Alegre (Brazil). We used simple random sampling, with sample size weight by the number of participants in each individual center. Several health domains were measured by self-reported questionnaires (e.g., cardiovascular risk factors and quality of life), office blood pressure measurements, blood assessments (i.e., lipid profile and HbA1c) and functional tests (i.e., 6-minute walk test and handgrip strength) between April/2018 to February/2019. The results are mostly reported using descriptive statistics. We observed that high self-reported prevalences regarded to cardiovascular risk factors, more specifically for sleep disorder (55%), hypercholesterolemia (54%) and hypertension (49%). Among self-reported diseases, the participants listed cardiovascular diseases (14%), previous cancer (15%), diabetes (13%), arthritis (30%), and depression (19%). The results observed in the 6-minute walk test (mean±sd 498±78.95 m) and handgrip test (mean±sd 27±8.13 kg) showed the expected levels for active elderly. Overall, the prevalences presented herein allow to contrast the estimated prevalences of older adults using a public program of physical activity to other populational estimates or single studies, fostering the future monitoring of assessments and interventions in sensible conditions (e.g., hypertension, sleep disorder) for this population. 

O conhecimento do perfil de saúde dos usuários de programas públicos para promoção em saúde pode otimizar a elaboração e aperfeiçoamento de intervenções para controle doenças ou de eventos associados ao estilo de vida, com potencial impacto para a saúde pública. O objetivo deste estudo foi caracterizar o perfil da situação de saúde dos usuários idosos do programa público de atividade física, em 11 centros comunitários da cidade de Porto Alegre (RS, Brasil). Entre abril/2018 e fevereiro/2019, foram medidos domínios de saúde por questionários autoaplicados, avaliações sanguíneas e testes funcionais. O tamanho amostral foi ponderado pela quantidade de alunos atendidos por centro, com amostragem por aleatorização simples. As análises basearam-se em estatística descritiva. No total, 351 idosos (69±6 anos) foram incluídos. Houve elevadas prevalências de fatores de risco, sendo transtorno do sono (55%), hipercolesterolemia (54%), e hipertensão arterial (49%) as mais altas. Entre as doenças autorrelatadas, os participantes listaram condições cardiovasculares (14%), câncer prévio (15%), diabetes (13%), artrite reumatóide (30%) e depressão (19%). A capacidade de caminhada em 6 minutos e força de preensão manual estiveram em níveis de pessoas ativas. Este estudo possibilita contrastar as condições prevalentes dos idosos usuários de um programa público de atividade física com estimativas populacionais, servindo como levantamento inicial para futuro monitoramento de avaliações e/ou intervenções específicas às condições sensíveis nesta população.

Health Academy Program: correlation between noncommunicable chronic disease hospitalizations and program adherence in Brazilian municipalities, 2011-2017. / Programa Academia da Saúde: correlação entre internações por doenças crônicas não transmissíveis e adesão nos municípios brasileiros, 2011-2017.

OBJECTIVE: To analyze the correlation between municipalities adhering to the Health Fitness Center Program, noncommunicable chronic disease (NCD) hospitalizations and socioeconomic levels from 2011 to 2017. METHODS: This was an ecological study; HFCP adherence indicators for 2,837 municipalities were calculated, as were NCD hospitalization indicators, according to funding categories and the Firjan Socioeconomic Development Index. RESULTS: The HFCP adherence indicator was higher for municipalities that received Congress funding (1.18), had moderate to high Firjan Socioeconomic Development Indices (0.94) and high NCD hospitalization indicators (1.03) (p<0.001). There were positive correlations (p<0.05) between the two indicators in municipalities receiving Ministry of Health funding (r=0.14) and those receiving both Congress and Ministry of Health funding (r=0.12); whereas correlation was negative in municipalities with moderate to low Firjan Socioeconomic Development Indices (r=-0.09; p=0.013). CONCLUSION: The main form of adherence to the HFCP, according to population size, was through Congress funding. Municipalities with poorer socioeconomic and NCD indicators had lower adherence to the HFCP.

Programa Academia da Saúde: um olhar quantitativo das adesões entre 2011 a 2017 / The Health Academy Program in Brazil: a quantitative view of adhesions between 2011 to 2017

O objetivo foi analisar a distribuição das adesões municipais ao Programa Academia da Saúde (PAS) no território nacional e o impacto da alteração do tipo de financiamento das obras no quantitativo de adesões. Foram utilizados dados secundários disponibilizados pelo Ministério da Saúde (MS) referentes às adesões ocorridas de 2011 a 2017 para compor as variáveis do estudo. Foram realizadas análises descritiva e inferencial, empregando-se o teste t pareado de Student para verificar diferenças entre adesões em diferentes anos e modalidades de financiamento (emenda parlamentar ­ EP e MS). Os resultados mostram que a maioria das macrorregiões apresentou mais de 50% de municípios participantes (municípios-PAS). As regiões Nordeste e Sudeste tiveram mais adesões, mas a região Norte destacou-se com o maior quantitativo de municípios-PAS proporcionalmente ao total de municípios. O período de maior expansão foi de 2011 a 2013. O número de adesões e municípios-PAS nos cinco anos de financiamento exclusivo por EP não superou o quantitativo aprovado de 2011 a 2012. Nos primeiros anos de financiamento por EP, ocorreu concentração das adesões nos mesmos municípios. Todas as macrorregiões apresentaram mais de 60% de obras concluídas, entretanto foi baixo o percentual de academias com custeio federal dentre as adesões aptas ao recebimento. Concluímos que o PAS está bem distribuído em todo o país, com diferentes situações de implantação. O período de maior expansão do programa foi em 2011 e 2012, quando as obras eram financiadas com recurso do MS. De 2013 a 2017, com financiamento exclusivo por EP, o quantitativo de adesões não superou o observado nos dois primeiros anos

This study aimed to analyze the adhesions of the Health Academy Program (HAP) in the country and the impact of the funding type alteration for the facilities building. Secondary data provided by the Minis-try of Health regarding the adhesions from 2011 to 2017 were used to compose the variables. Descriptive and inferential analyses were conducted, using the Student's paired t-test to verify differences between the number of adhesions to the HAP in different years and funding types. Most regions had more than 50% of participating municipalities. Northeast and Southeast presented greater adhesions numbers concerning the other regions, but the North was highlighted with the largest quantity proportional to the number of municipalities. The greatest expansion was from 2011 to 2013. The number of facilities and municipalities enrolled in the HAP during the years of exclusive funding by parliamentary amendments did not exceed the amount approved from 2011 to 2012. There was a concentration of adhesions in the same municipalities in 2012 and 2013 when the parliamentary amendments were included. In all regions, the rate of facility building completion was above 60%, however the percentage of facilities with the maintenance funding among those able to receive it is low. In conclusion, the HAP has been largely implemented in the country, with a variety of implementation status. From 2011 to 2012 occurred the greatest expansion of the HAP, period that the facilities where financed with funds from the Ministry of Health. In the others hand, from 2013 to 2017, with exclusive funding by EP, the number of facilities did not exceed that observed in the first two years

Objetivo: Analisar a correlação entre adesão dos municípios ao Programa Academia da Saúde, internações por doenças crônicas não transmissíveis (DCNT) e níveis socioeconômicos, no período 2011-2017. Métodos: Estudo ecológico; foram calculados indicadores de adesão (IND-ADE) de 2.837 municípios brasileiros ao PAS, e de internações por DCNT (IND-DCNT), segundo categorias de financiamento e o Índice Firjan de Desenvolvimento Socioeconômico (IFDM). Resultados: O IND-ADE foi maior nos municípios financiados por emendas parlamentares (1,18), com IFDM moderado a alto (0,94) e IND-DCNT alto (1,03) (p<0,001). Houve correlação positiva (p<0,05) entre IND-ADE e IND-DCNT em municípios contemplados com recursos do Ministério da Saúde (r = 0,14) e de ambos os tipos, emendas parlamentares e programa ministerial (r=0,12); e correlação negativa em municípios com IFDM moderado a baixo (r=-0,09; p=0,013). Conclusão: A principal forma de adesão ao PAS, referenciada pelo porte populacional, foi emenda parlamentar. Municípios com piores indicadores socioeconômicos e de DCNT apresentaram menor adesão.

Objetivo: Analizar la relación entre adhesión de los municipios al Programa Federal Academia de la Salud y las hospitalizaciones por enfermedades crónicas no trasmisibles (ECNT) y niveles socioeconómicos entre 2011 y 2017. Métodos: Estudio ecológico; se calcularon los indicadores de adhesión (IND-ADH) de 2.837 municípios brasileños al PAS y de hospitalizaciones por enfermedades crónicas no transmisibles (IND-ECNT) según las categorías de financiación y el Índice Firjan de Desarrollo Socioeconómico (IFDM). Resultados: El IND-ADH fue alto en municipios financiados mediante enmiendas parlamentarias (1,18), el IFDM moderado a alto (0,94) y el indicador ECNT alto (1,03) (p<0,001). Hubo correlaciones significativas (p<0,05) entre los indicadores IND-ADH e IND-DCNT en municipios con financiamiento del Ministerio de Salud (r = 0,14) y mixtos (r=0,12); hubo correlación negativa para municipios con IFDM moderado a bajo (r=-0,09; p=0,013). Conclusión: La enmienda parlamentaria fue la forma principal de adhesión al PAS de los municipios, cuando ajustada por la población. Los municipios con los peores indicadores socioeconómicos y de ENT tuvieron un IND-ADH más bajo.

Physical Activity and Sitting Time Are Specifically Associated With Multiple Chronic Diseases and Medicine Intake in Brazilian Older Adults.

The purpose of the study was to clarify the independent association between sedentary behavior and physical activity with multiple chronic diseases and medicine intake in older individuals. Sedentary behavior and physical activity were measured by questionnaires. Diseases and medication use were self-reported. Poisson's regression was adopted for main analysis, through crude and adjusted prevalence ratio and confidence interval of 95%. For men, sedentary time >4 hr/day presented a 76% higher prevalence of ≥2 chronic diseases, while physical inactivity increases the likelihood of using ≥2 medicines in 95%. For women, sedentary behavior >4 hr/day presented an 82% and 43% greater prevalence for ≥2 chronic diseases and the intake of ≥2 medicines, respectively. Sedentary behavior represents an independent associated factor of multiple chronic diseases in older men and women. In addition, inactivity for men and sedentarism for women are associated with the amount of medicine intake.

Application of modified simplex on the development of a preconcentration system for cadmium determination in sediments, food and cigarettes.

A modified simplex algorithm was used to optimize a system of preconcentration for cadmium determination in samples of sediments, cigarettes and food using flame atomic absorption spectrometry. The preconcentration system is based on the sorption of cadmium in a minicolumn packed with Amberlite XAD-2 resin functionalized with 3,4-dihydroxybenzoic acid (DHB). The optimized variables were pH and sampling flow rate and the optimum conditions found for these variables were, respectively 8.7 and 8.8 mL min-1. The developed system showed a preconcentration factor of 15.3, detection limit of 0.49 µg L-1, quantification limit of 1.65 µg L-1 and precision expressed as relative standard deviation (% RSD, n=10) of 5.9. The accuracy of the method was checked by analysis of estuary sediment certified reference material (NIST 1646-1). The cadmium concentrations found in sediment samples ranged from 1.73 and 1.90 µg g-1. In cigarette samples the results were 0.085 and 0.193 µg g-1, and in food samples (coriander and lettuce) the concentrations found of this metal were, respectively, 0.33 and 0.12 µg g-1.

Fitness but not weight status is associated with projected physical independence in older adults.

Obesity and fitness have been associated with older adults' physical independence. We aimed to investigate the independent and combined associations of physical fitness and adiposity, assessed by body mass index (BMI) and waist circumference (WC) with the projected ability for physical independence. A total of 3496 non-institutionalized older adults aged 65 and older (1167 male) were included in the analysis. BMI and WC were assessed and categorized according to established criteria. Physical fitness was evaluated with the Senior Fitness Test and individual test results were expressed as Z-scores. Projected ability for physical independence was assessed with the 12-item composite physical function scale. Logistic regression was used to estimate the odds ratio (OR) for being physically dependent. A total of 30.1 % of participants were classified as at risk for losing physical independence at age 90 years. Combined fitness and fatness analysis demonstrated that unfit older adults had increased odds ratio for being physically dependent in all BMI categories (normal: OR = 9.5, 95 %CI = 6.5-13.8; overweight: OR = 6.0, 95 %CI = 4.3-8.3; obese: OR = 6.7, 95 %CI = 4.6-10.0) and all WC categories (normal: OR = 10.4, 95%CI = 6.5-16.8; middle: OR = 6.2, 95 %CI = 4.1-9.3; upper: OR = 7.0, 95 %CI = 4.8-10.0) compared to fit participants that were of normal weight and fit participants with normal WC, respectively. No increased odds ratio was observed for fit participants that had increased BMI or WC. In conclusion, projected physical independence may be enhanced by a normal weight, a normal WC, or an increased physical fitness. Adiposity measures were not associated with physical independence, whereas fitness is independently related to physical independence. Independent of their weight and WC status, unfit older adults are at increased risk for losing physical independence.

Efeitos de diferentes programas de exercícios físicos sobre a composição corporal e a autonomia funcional de idosas com risco de fratura / Effects of different exercise programs on body composition and functional autonomy in elderly women with fracture risk

Com o envelhecimento, ocorre um decréscimo da autonomia funcional dos indivíduos, predispondo-os a quedas, sendo o exercício uma ferramenta para atenuar tais efeitos e melhorar a qualidade de vida desses indivíduos. O objetivo deste trabalho foi analisar os efeitos de diferentes programas de exercícios físicos sobre medidas antropométricas (MA) e autonomia funcional (AF) de idosas com risco de fratura. Quarenta idosas (com risco de fraturas) foram submetidas a 35 sessões (1h, 2 vezes/semana) de treinos de musculação (GM, n= 13), ou ginástica funcional (GF, n= 12) ou ginástica aeróbica (GA, n= 15). Foram avaliadas as MA e a AF antes e após os treinamentos. Não foram observadas melhoras nas MA após 35 sessões nos três grupos. Já a AF apresentou melhoras nos testes de levantar da posição sentada (p<0,001; Δ%=-15; magnitude do efeito=-0,76), levantar da posição em decúbito ventral (p<0,001; Δ%=-20; ME=-0,62) e no índice geral (p<0,001; Δ%=-10; magnitude do efeito=-0,68) no GM. No teste de caminhar 10m houve interação entre tempo x treino (p= 0,048), demonstrando maior magnitude do efeito no GM (Δ%=-6,0; magnitude do efeito=-0,50). Conclui-se que a musculação é mais eficiente na melhora da AF, quando comparada a ginástica funcional e aeróbica em idosas com risco de fraturas.

Functional autonomy can decrease with aging, predisposing the individuals to falls, exercise being a tool to mitigate these effects and improve the quality of life of these individuals. The aim of this study was to analyze the effects of different exercise programs on anthropometric measurements (AM) and functional autonomy (FA) in elderly women with fracture risk. Forty women (with fracture risk) underwent 35 sessions (1 hour, 2 times/week) strength training group (STG, n= 13) or functional group (FG, n= 12) or aerobics group (AG, n= 15). We have measured the AM and FA before and after training. No improvements in AM after 35 sessions were observed in the three groups. Since the FA showed improvement standing from a sitting position (p<0.001, Δ%=-15, effect size= -0.76), up from prone position (p<0.001, Δ%=-20, effect size=0.62) and general index (p<0.001, Δ=-10%, effect size=-0.68)] in STG. In walking 10m test was interaction between time x training (p=0.048), showing a greater effect size on STG (Δ%=-6,0, effect size=-0.50). We conclude that strength training is more effective in improving the FA when compared to functional and aerobics in elderly women with fracture risk.

Efeito do treinamento aquático no perfil lipídico e na hipertrofia ventricular esquerda de camundongos hiperlipidêmicos / Effect of water training on the lipid profile and left ventricular hypertrophy in hyperlipidemic mice

O objetivo do presente estudo foi analisar os efeitos do treinamento aquático (TA) no perfil lipídico e nas estruturas ventriculares esquerdas de camundongos hiperlipidêmicos. Foram utilizados 28 camundongos LDLr-/-, machos, divididos aleatoriamente em 4 grupos: sedentários alimentados com ração padrão (C); treinados alimentados com ração padrão (C+TRE), sedentários alimentados com ração hiperlipídica (HL) e treinados alimentados com ração hiperlipídica (HL+TRE). Os animais dos grupos treinados praticaram TA em intensidade moderada, por 60 minutos durante 60 dias consecutivos. Após 48 horas do término do período de treinamento e 12 horas de jejum de repouso os animais foram eutanasiados, o sangue coletado e o soro utilizado para análises laboratoriais de triglicérides, colesterol total e suas frações (LDL, HDL, VLDL). O coração foi removido e o ventrículo esquerdo foi pesado a fresco para se calcular a proporção do peso ventricular esquerdo (mg)/ peso do animal (g). Os resultados mostraram que o TA sem cargas adicionais foi mais eficiente na melhora das concentrações plasmáticos de lipídeos quando acompanhado por uma dieta adequada, confirmando que a associação exercício físico com dieta equilibrada é essencial para obtenção de seus benefícios. O treinamento ocasionou hipertrofia ventricular esquerda excêntrica no grupo alimentado com dieta padrão e, principalmente, diminuiu o depósito de colágeno intersticial no miocárdio dos animais alimentados com dieta hiperlipídica, o que pode indicar uma melhora na função diastólica com consequente melhora da função sistólica. Concluiu-se que o treinamento aquático de intensidade leve a moderada induz adaptações benéficas e profiláticas ao coração, promovendo saúde e prevenindo doenças.

This study assessed the effects of Water training on the lipid profile and left ventricular structures in hyperlipidemic mice. Twenty-eight male LDLr-/- mice were randomly separated into 4 groups: sedentary, fed a standard diet (C); exercising, fed a standard diet (C+TRE); sedentary, fed a hyperlipidic diet (C+HL); and exercising, fed a hyperlipidic diet (E+HL). The exercising mice trained daily for 60 minutes during 60 days. After 48 hours of the end of the training period and 12 hours of rest fasting the animals were underwent euthanasia and the blood was collected for measuring the plasma levels of triglycerides, total cholesterol and its fractions (LDL, HDL, VLDL). The heart was removed and the left ventricle was weighed fresh to calculate the ratio left-ventricle weight (mg)/body weight (g). The results showed that the training was more effective in improving lipid plasma levels when combined with a balanced diet, thereby confirming that it is essential to associate physical exercise and diet. The training protocol resulted in eccentric left ventricular hypertrophy in the standard-diet group and decreased interstitial collagen deposition in the myocardium of the high-fat-diet animals, which may indicate an improved diastolic function with consequent improvement in the systolic function. It was concluded that regular moderate aerobic exercise induce beneficial and prophylactic adaptations to heart which promoted a better health condition and prevention to diseases.
