IntroductionAgility training (AT) is used to improve neuromuscular performance and dynamic balance, which are crucial for the physical function of older adults. Activities of daily living, which decrease with age, involve tasks that simultaneously require motor, and cognitive abilities and can be considered dual tasks.MethodsThis study investigates a training program's physical and cognitive effects using an agility ladder on healthy older adults. This program consisted of 30-min sessions twice per week and lasted for 14 weeks. The physical training included four different sequences with progressive difficulty levels, while the cognitive training (CT) included different verbal fluency (VF) tasks for each physical task. Sixteen participants (mean age of 66.9 ± 5.0 years) were allocated to two groups: AT alone (AT) and dual-task training (AT combined with CT [AT + CT]). Assessments were performed before and after 14 weeks of interventions using physical functional tests (e.g., Illinois agility test, five times sit-to-stand test, timed up and go [TUG], and one-leg stand) and cognitive tests (cognitive TUG, verbal fluency, attention, and scenery picture memory test).ResultsAfter this period, both groups had significant differences in physical performance, muscle power, agility, static and dynamic balance, and short-term memory, whereas only the AT + CT group improved phonological verbal fluency, executive function (TUG combined with a cognitive task), attention (trail-making test-B), and short-term memory (scenery picture memory test).ConclusionIndicating that only the group that received direct cognitive training had better enhanced cognitive function.Clinical trial registrationwww.ClinicalTrials.gov, identifier: RBR-7t7gnjk.

Background and Objectives: Evidence suggests that the failure of epidemiological control impedes the resumption of socioeconomic activities. Therefore, this study aimed to describe epidemiological aspects and the pattern of mobility on each continent and to verify the association between the COVID-19 infection rate and time spent at home. Methods: We analyzed reports from Global Positioning System of 97 countries and their epidemiological indicators until May 27, 2020. Results: Cases of COVID-19 ranged from 22 to 1,745,803, and deaths ranged from 0 to 102,107. The highest rates per 100,000 population were observed in Europe and America. Approximately 54% of COVID-19 cases occurred in America and 51% of deaths in Europe. Countries reduced mobility in retail and recreation (-43.45%±20.42%), grocery and pharmacy (-17.95%±20.82%), parks (-18.77%±37.34%), transit stations (-43.09%±20.31%), workplaces (-21.74%±19.92%), and increased time spent at home (13.00%±8.80%). Linear regression showed that European inhabitants stayed at home less when compared those on the American continent (β=-4.933, SE=0.976, p

The aim of this experimental study was to evaluate acute responses to oxidative stress (OS) after a single session of two HIIT protocols. 24 Wistar rats were divided into three groups (n= 8): sedentary control (SC), HIIT with a 7-minute volume (LW) and HIIT with 14-min (HW). After the protocol, blood was collected for the measurement of uric acid (UA), and the liver and the gastrocnemius muscle were collected for OS assessment by measuring malondialdehyde (MDA) and total antioxidant capacity (FRAP). The LW and HW groups showed a reduction in hepatic MDA (51.9 and 29.9%; p< 0.05) compared to SC. However, the muscle of the HW group increased the MDA (12.6%; p< 0.05) compared to SC. As for FRAP, LW and HW reduced values (78.3 and 75.3%; p< 0.05, respectively) compared to SC. UA in the LW group was higher when compared to SC (64.7%; p< 0.05), HW group was similar to SC (p> 0.05). Among the different HIIT protocols, the LW group showed an increase in UA compared to the HW group (44%; p< 0.05). Compared to SC, the LW and HW groups did not promote acute OS in the liver tissue. However, HW caused OS in muscle tissue after a single exercise session.

O presente estudo teve como o objetivo analisar a frequência de atividade física, consumo alimentar e nível nutricional de servidores públicos. A amostra foi composta por 15 servidores públicos, com idades entre 18 e 60 anos, de ambos os sexos. Realizou-se a aferição do peso corporal (kg), estatura (m) e posterior cálculo do IMC (kg/m2). Foram medidas as seguintes circunferências: abdominal e quadril. Foi obtido o índice de relação entre os perímetros da cintura e quadril (circunferência de cintura /circunferência do quadril). Foi observado consumo de frituras semanalmente, doces e açúcares diariamente. Álcool semanalmente. Ingestão média diária de oito copos de água, sucos e refrigerantes. Em relação à atividade física: LEVE: cinco pessoas treinam 4 vezes/semana, 3 pessoas treinam 5 vezes/ semana, 2 pessoas treinam 2 vezes/semana. E apenas 2 treinam sete vezes/ semana. Nesses, média de 1 hora/dia. Apenas 2 pessoas treinam mais que duas horas/dia. Nenhuma amostra relatou atividade MODERADA. A composição corporal no início da análise foi verificada que apenas 01 amostra (7,14%) estava com IMC normal. 40% (n=6) apresentaram sobrepeso e aumento da relação cintura quadril. 42,85% (n=6) com IMC Obesidade Grau I. 7,14% (n=1) apresentou Obesidade Grau II. A amostragem é de risco pelo fato de ainda apresentarem IMC compatível com Sobrepeso/Obesidade. Recomenda-se um programa de intervenção nutricional, nesses indivíduos, atividades físicas regulares e moderadas para melhoria do perfil antropométrico.

O objetivo do estudo foi identificar as estruturas para atividades físicas (AF) nas escolas brasileiras e relacioná-las ao Índice de Desenvolvimento Humano (IDH), Índice de Desenvolvimento da Educação Básica (IDEB) e indicadores de qualidade do Report Card Brasil (RCB). Trata-se de estudo descritivo que utilizou dados secundários do INEP-Brasil para a identificação e classificação da estrutura para prática de AF nas escolas brasileiras, a partir da existência de “pátio”, “quadras” e “materiais esportivos”, organizadas por escolas do nível “fundamental” e “médio”. Os dados foram organizados por Região Macroeconômica e relacionados com os Índices IDH, IDEB e os Critérios de Classificação de Qualidade do RCB. Assim, para o “Ensino Fundamental”, verificou-se relação positiva entre o IDH e a existência de “pátio” (r=0,53; p=0,004), “quadra” (r=0,855; p

Objetivou-se identificar a evidência quanto às associações entre atividade física (AF) e saúde mental (SM) em adolescentes escolarizados brasileiros. Trata-se de um estudo de Revisão Sistemática. Os estudos foram selecionados em português e inglês e identificados por meio de uma busca sistemática em seis bases de dados eletrônicas: PubMed, Web of Science, SPORTDiscus/Ebsco, ScIELO, ERIC, e LILACS, que compreendeu publicações até o final de 2019. Os critérios de inclusão foram: estudos com um desenho de coorte, descritivo de caráter exploratório, transversal, ou qualitativos; realizados com crianças e adolescentes; estudos que analisaram a relação entre AF e SM; estudos que investigaram adolescentes que praticavam AF nas escolas; estudos realizados no Brasil e os que obtiveram a pontuação mínima estabelecida de 60% conforme os critérios da qualidade metodológica do instrumento STROBE. A Educação Física oferecida no currículo da educação básica tem um efeito protetor sobre a SM no ambiente escolar. Além disso, mais de 300 min/semana de AF foi associado positivamente com a SM. Algumas associações foram negativas entre a AF e a SM, tais como: tempo excessivo de TV; isolamento social; insatisfação com o peso corporal. A AF escolar está associada positivamente à SM por promover bem-estar físico e psicológico, impactando na redução dos índices de problema de insônia, atenuando a solidão e melhorando a aparência física.

The objective of this systematic review was to identify the association between overweight/obesity and level of physical activity in Brazilian children and adolescents in the school setting. For search strategy, the main reference databases (PubMed, LILACS, SciELO, SPORTDiscus, Web of Science, ERIC) were used. Baseline searches resulted in 3,265 potentially relevant titles (2,775 titles after removal of duplicate studies); 21 studies met all inclusion criteria and were included for analysis. Studies were carried out from 2007 to 2019; 47.6% of them were conducted in Southern Brazil, and only one study had nationwide approach. Prevalence from 5.4% to 21% was identified for overweight, 3.5% to 16.9% for obesity and 11.8% to 40.1% for overweight + obesity. According to results, 64.3% of overweight, 69.8% of obese and 37.7% of young overweight people were considered insufficiently active. The non-standardization of instruments to assess levels of physical activity and the lack of information regarding other Brazilian regions were classified as important limitations. The results reinforce the increase in the prevalence of overweight in Brazilian children and adolescents, and the high prevalence of physical inactivity among them. For every ten overweight children/adolescents, six are reported to be insufficiently active.

Resumo: Introdução: A educação interprofissional (EIP) desenvolve competências colaborativas, aprimora a segurança do paciente e melhora a qualidade da atenção à saúde. A disponibilidade para aprendizagem compartilhada relaciona-se diretamente com a EIP. Objetivo: Este estudo teve como objetivo analisar a disponibilidade dos estudantes para a EIP, de acordo com os ciclos e cursos. Método: Trata-se de estudo transversal, descritivo, de abordagem quantitativa. Utilizou-se a Readiness for Interprofessional Learning Scale (RIPLS) via formulário eletrônico. Os testes Mann-Whitney e qui-quadrado foram utilizados para analisar respectivamente variáveis contínuas e categóricas. Nas análises para verificar as diferenças nas pontuações dos fatores 1. trabalho em equipe e colaboração (TEC), 2. identidade profissional (IP) e 3. atenção à saúde centrada no paciente (ACP), além da pontuação global da RIPLS, os cursos e ciclos foram comparados por meio do teste Kruskal-Wallis. Resultado: Participaram do estudo 506 estudantes, com taxa de respostas de 32,6%, dos cursos de Enfermagem, Farmácia, Fisioterapia, Fonoaudiologia, Medicina, Nutrição, Odontologia e Terapia Ocupacional de uma universidade pública brasileira. As pontuações dos fatores 1, 2 e 3 e a pontuação global da RIPLS não apresentaram diferenças entre os sexos. Os estudantes do curso de Farmácia apresentaram menor disponibilidade para o fator 3 (ACP) quando comparados com os alunos de Enfermagem, Fisioterapia, Medicina, Odontologia e Terapia Ocupacional (p = 0,007). Os discentes de Fonoaudiologia e Nutrição apresentaram menor pontuação no mesmo fator em comparação com os de Odontologia e Terapia Ocupacional (p = 0,007). Os estudantes de Farmácia (p = 0,004) e Medicina (p = 0,016) foram menos propícios a obter maior pontuação no fator 1 (TEC), enquanto os de Terapia Ocupacional obtiveram maior chance para maior disponibilidade no mesmo fator (p = 0,024). No fator 2 (IP), os estudantes do quinto ciclo foram menos propensos a atitudes positivas (p = 0,046). Observou-se que os estudantes de Terapia Ocupacional apresentaram atitude mais favorável para a EIP expressa tanto no fator 3 (p = 0,034) quanto na pontuação global (p = 0,027), enquanto os alunos do curso de Farmácia apresentaram menor chance para melhor disponibilidade no fator 3 (p = 0,003) e na pontuação global (p = 0,003). Conclusão: Considerando a relevância da EIP no processo de reorientação da formação de profissionais de saúde para a construção da integralidade do cuidado e alinhamento com o Sistema Único de Saúde, este estudo pretende contribuir para a reflexão acerca das diferenças na disponibilidade para EIP entre cursos de graduação na área da saúde.

Abstract Aim: This study aimed to examine the association between physical activity (PA) indicators and TV viewing as a function of the Human Development Index (HDI). Method: This cross-sectional study was based on data from the National School Health Survey, which was composed of 102,072 students (14.28±1.03; 51.3% girls). Total PA, active commuting to school (ACS) and TV viewing were assessed by questionnaires and classified through a gradual scale ranging from “F” (low) to “A+” (high). The correlation between total PA, ACS, TV viewing and HDI was verified by Spearman’s Correlation and presented in rs. Results: HDI was positively associated with total PA [girls: rs = 0.572 (p < 0.001); boys: rs = 0.843 (p < 0.001)] and ACS [girls: rs = 0.433 (p < 0.001); boys: rs = 0.554 (p < 0.001)]; while a negative correlation was found between HDI and TV viewing [girls: rs = -0.330 (p < 0.001); boys: rs = -0.348 (p < 0.001)]. Conclusions: Brazilian adolescents from states with higher HDI were more active and spent more time watching TV than their counterparts from states with lower HDI.

The purpose of this study was to analyze the factors associated with negative Health Perception and Quality of Life (QoL) of older adults. This was a cross-sectional study composed of 224 older adults with a median age of 70.58±6.43 years old. A questionnaire was designed to incorporate ABEP (socioeconomic questionnaire), WHOQOL-BREF, IPAQ, and Senior Fitness Test (SFT). Binary logistic regression with p>0.05, organized in univariate and multivariate models in SPSS version 22. Variables upper extremities poor flexibility OR = 2.43 (1.37 – 4.31) and lower extremities poor flexibility OR = 2.69 (1.54 – 4.69) were significantly associated with negative health perception. Being not financial responsible OR= 0.33 (0.12 – 0.85) presented lower odds of negative QoL perception. The variable Lower extremities poor flexibility univariate OR= 2.52 (1.45 – 4.39) and multivariate model OR= 2.42 (1.38 – 4.24) showed almost three times higher probabilities of negative QoL perception.

Aging comprises a dynamic and progressive process, characterized by physiological and functional changes. Among these changes, increase in body fat is considered relevant, since it can leads to impaired physical fitness and augmented cardiometabolic risks. Considering this, the objective of this study was to evaluate the influence of overweight on functional capacity of physically active older women. A field survey was performed with 24 older women who practiced physical exercise. Participants were submitted to anamnesis, anthropometric measures (i.e., body mass and height); the Senior Fitness test; sit and reach flexibility test; and handgrip strength test. Pearson’s correlation test and multivariate logistic regression were used to verify the association between overweight and functional capacity. It was observed that hip flexibility (R=-0.494, p=0.014) and flexibility of the lower limbs (i.e., sit and reach test) showed negative correlation with the body mass index (R=-0.446, p=0.02); and after the multivariate logistic regression, negative correlation of lower limbs flexibility (B= -0,035, p=0,014) and the body mass index was observed. Thus, higher the body mass index among participants, lower hip flexibility they presented.

ABSTRACT CONTEXT AND OBJECTIVE: Sarcopenia is an emerging public health issue in Brazil. Because of its high prevalence and the lack of national data, the objective here was to identify cutoff points for appendicular skeletal muscle (ASM) and handgrip strength in relation to fear of falling among Brazilian older adults. DESIGN AND SETTING: Cross-sectional study; in the community. METHODS: Participants underwent morphological and functional evaluations; and were asked about previous falls and fear of falling. Different adjustments to ASM and handgrip strength were used. Slow walking speed was defined as < 0.8 m/s or 1.0 m/s. Gender and age groups were compared using t tests, analysis of variance (ANOVA), chi-square test or Fisher’s exact test. Receiver operating characteristic curves were used to identify cutoffs for ASM and handgrip strength in relation to fear of falling. RESULTS: 578 older adults participated in this study. Function levels decreased with increasing age, and body composition differed between the sexes. In relation to fear of falling, the cutoffs for ASM adjusted for body mass index (BMI) were < 0.85 for men and < 0.53 for women; the cutoffs for absolute handgrip strength and relative handgrip strength (adjusted for BMI) were 30.0 kgf and 21.7 kgf, and 1.07 and 0.66, for men and women, respectively. CONCLUSION: The values presented can be used as references in clinical practice and research. We recommend use of ASM adjusted for BMI and choosing between absolute and relative handgrip strength for men and women, according to study needs.

Introduction. Sarcopenia is a geriatric syndrome associated with impairment of muscle function, metabolism, and cognition in older women. Recent studies have shown a relationship between changes in muscle mass and the cardiovascular system. However, this relationship has not been fully elucidated. Methods. One hundred and thirty community-dwelling Brazilian older women (65.4 ± 6.3 years) were recruited to participate in this study. Data on body composition (via bioelectrical impedance measurements), cardiovascular parameters (using an automatic and noninvasive monitor), and muscle function (using a 3-meter gait speed test) were measured. Results. Sarcopenic older women (n=43) presented higher levels of pulse pressure (PP) (60.3 ± 2.6 mmHg) and lower muscle function (0.5 ± 0.0 m/s) compared with nonsarcopenic subjects (n=87) (53.7 ± 1.5 mmHg; 0.9 ± 0.0 m/s) (P

No exercício resistido (ER), a hipertrofia muscular pode ser estimulada pela tensão (caracterizados pelo uso de cargas elevadas, descansos maiores entre as séries e ênfase na fase excêntrica da contração) e pelas mudanças metabólicas (cargas e períodos de descansos menores, e maior número de repetições por série) impostas à fibra muscular. Assim, o objetivo deste estudo foi comparar em adultos jovens, as respostas agudas de frequência cardíaca (FC), pressão arterial sistólica (PAS), pressão arterial diastólica (PAD) e duplo produto (DP) entre duas sessões de ER, uma com característica tensional e outra metabólica. Quatorze homens (24,1 ± 3,43 anos; 172,9 ± 5,13 cm; 77,6 ± 7,9 kg; gordura relativa = 15,2 ± 4,3 %; força relativa = 5 ± 1,1), normotensos, aparentemente saudáveis e fisicamente ativos no ER foram submetidos à duas sessões de treinamento, ambas compostas por 3 séries realizadas no Leg Press 45º. A primeira sessão foi a metabólica (15 repetições com 2 seg para cada fase, 50% da carga máxima e 1 min de descanso) e 72 horas após, a tensional (6 repetições com 4 seg para a fase excêntrica e 2 seg para a concêntrica, 70% da carga máxima e 2 min de descanso). Por meio do Test “t” de Student não-pareado (p

ABSTRACT CONTEXT AND OBJECTIVE: In elderly people, measurement of several anthropometric parameters may present complications. Although neck circumference measurements seem to avoid these issues, the cutoffs and cardiovascular risk factors associated with this parameter among elderly people remain unknown. This study was developed to identify the cutoff values and cardiovascular risk factors associated with neck circumference measurements among elderly people. DESIGN AND SETTING: Cross-sectional study conducted in two community centers for elderly people. METHODS: 435 elderly adults (371 women and 64 men) were recruited. These volunteers underwent morphological evaluations (body mass index and waist, hip, and neck circumferences) and hemodynamic evaluations (blood pressure values and heart rate). Receiver operating characteristic curve analyses were used to determine the predictive validity of cutoff values for neck circumference, for identifying overweight/obesity. Multivariate analysis was used to identify cardiovascular risk factors associated with large neck circumference. RESULTS: Cutoff values for neck circumference (men = 40.5 cm and women = 35.7 cm), for detection of obese older adults according to body mass index, were identified. After a second analysis, large neck circumference was shown to be associated with elevated body mass index in men; and elevated body mass index, blood pressure values, prevalence of type 2 diabetes and hypertension in women. CONCLUSION: The data indicate that neck circumference can be used as a screening tool to identify overweight/obesity in older people. Moreover, large neck circumference values may be associated with cardiovascular risk factors.
