Associação entre declínio cognitivo, sintomas depressivos e do medo de cair com a velocidade da marcha confortável em idosos comunitários / Association between cognitive decline, depressive symptoms and the fear of falling with the speed gait in community-dwelling older adults

Diminuições na velocidade da marcha (VM) estão associadas a desfechos adversos na saúde física e mental em idosos. Assim, torna-se relevante identificar fatores que podem associar-se com a VM confortável em idosos, de forma a propor estratégias para prevenção de alterações na mobilidade. Objetivo: verificar a associação entre declínio cognitivo, sintomas depressivos e do medo de cair com a VM confortável em idosos comunitários. Métodos: tratou-se de um estudo transversal, com amostra probabilística, incluindo 308 idosos comunitários. O desfecho do estudo foi a VM confortável, sendo considerado como baixo desempenho VM < 0,8m/s. As variáveis preditoras foram 1) declínio cognitivo avaliado pelo Mini Exame do Estado Mental, 2) sintomas depressivos avaliados com a Escala de Depressão Geriátrica Abreviada e 3) medo de cair avaliado pela Falls Efficacy Scale ­ Brasil. Para analisar a associação entre as variáveis foi utilizada a Regressão Logística Multivariada. Resultados: idosos tiveram chances significativamente maiores de apresentar baixo desempenho na VM confortável quando apresentaram declínio cognitivo (OR: 4,67; IC95%: 1,68; 12,94), sintomas depressivos (OR: 2,90; IC95%: 1,42; 5,92) e medo de cair (OR: 4,08; IC95%: 1,72; 9,71) quando comparados aos que não tiveram essas condições. Conclusão: o declínio cognitivo, sintomas depressivos e medo de cair foram associados ao baixo desempenho na VM confortável nos idosos amostrados. Esses achados podem servir para identificação precoce dos fatores que estão associados a alterações na VM confortável, contribuindo para a proposição de estratégias públicas em saúde e no direcionamento de atividades de promoção em saúde para idosos comunitários.(AU)

Decreases in gait speed (GS) are associated with adverse outcomes in the physical and mental health of the elderly. Thus, it is relevant to identify factors that can be associated with comfortable GS in community-dwelling older adults, to propose strategies to prevent changes in mobility. Objective: To verify the association between cognitive decline, depressive symptoms, and fear of falling with comfortable GS in community-dwelling older adults. Methods: This was a cross-sectional study with a probabilistic sample, including 308 community-dwelling older adults. The study outcome was comfortable GS, being considered as low-performance MV < 0.8m/s. Predictive variables were 1) cognitive decline assessed by the Mini-Mental State Examination, 2) depressive symptoms assessed by the Abbreviated Geriatric Depression Scale, and 3) fear of falling assessed by the Falls Efficacy Scale - Brasil. Multivariate Logistic Regression was used to verify the association between the variables. Results: Community-dwelling older adults were significantly more likely to have poor performance in comfortable GS when they presented cognitive decline (OR: 4.67; 95%CI: 1.68; 12.94), depressive symptoms (OR: 2.90; 95%CI: 1 .42; 5.92), and fear of falling (OR: 4.08; 95%CI: 1.72; 9.71) when compared to those who did not have these conditions. Conclusion: Cognitive decline, depressive symptoms, and fear of falling were associated with poor performance in comfortable GS in the community-dwelling older adults sampled. These findings can serve for early identification of factors that are associated with changes in comfortable GS, contributing to the proposition of public health strategies and in directing health promotion activities for community-dwelling older adults.(AU)

Functional Classification Spaces according to walking speed in self-sufficient Chilean older adults: A complement to the Periodic Physical Examination / Espacios de Clasificación Funcional según velocidad de marcha aplicada a adultos mayores autovalentes chilenos: Un complemento al Examen de Medicina Preventiva

Introduction Walking speed is related to functionality in daily activities. Preventive Medicine Examination of the Chilean older adults is a vital prevention program for Chilean community- dwelling older adults. However, this evaluation does not include speed in its battery of tests. Objective To evaluate the functional classification spaces for threshold, reference, and categorization val-ues of self- selected and maximum walking speed applied to self- sufficient older adults. Methods Seventy- two self- sufficient older adults participated in this observational, exploratory, and cross- sectional study. Each participant was asked to walk naturally and then at full speed for three minutes. Through a dispersion graph between self- selected walking speed (axis "x") and maximum walking speed (axis "y"), functional classification spaces were constructed according to documented values for i) thresholds of basic functionality, ii) referential for the instrumental spectrum and iii) functional categorization for "household walker" (< 0.4 meters per second, m/s), "limited community ambulator" (0.40 to 0.80 m/s), "community ambulator" (0.81 to 1.3 m/s), and "cross street safely" (> 1.3 m/s). The relative frequency (%) of older adults who meet each established quadrant was determined. Results The threshold was reached by 100% of the participants (basic daily activities). About 80% of the older adults have a functional classification space below the reference limit (instrumental and advanced daily activities). It was also found that 81% of women and 69% of men are "efficient in the community", and 31% of men and 14% of women reach the minimum value for "effec-tive street crossing" (advanced daily activities). Conclusions The exploration of functional classification spaces according to self- selected walking speed and maximum walking speed applied to a group of self- sufficient older adults reveals that this pop-ulation is at risk of deteriorating instrumental and advanced activities of daily living.

Introducción La velocidad de marcha se relaciona con la funcionalidad en actividades cotidianas. El Examen de Medicina Preventiva del Adulto Mayor es un hito relevante en la prevención de adultos mayores chilenos de la comunidad. Sin embargo, no incorpora a la velocidad dentro de su batería de pruebas. Objetivo Evaluar una propuesta complementaria al Examen de Medicina Preventiva del Adulto Mayor según Espacios de Clasificación Funcional para valores umbrales, referenciales y de categorización de velocidad de marcha confortable y máxima aplicada a personas mayores autovalentes. Métodos Participaron en este estudio observacional, exploratorio y transversal 72 adultos mayores autovalentes. Se solicitó a cada participante caminar naturalmente y luego a máxima velocidad durante 3 minutos. A través de un gráfico de dispersión entre velocidad de mar-cha confortable (eje "x") y máxima (eje "y"), se construyeron Espacios de Clasificación Funcional según valores documentados para i) umbrales de funcionalidad básica, ii) referenciales para el espectro instrumental y iii) categorización funcional para actividades "dentro del hogar" (< 0,4 m/s), "limitadas en la comunidad" (0,40 a0,80 m/s), "eficiente en la comunidad" (0,81 a1,3 m/s) y "cruce seguro de calles" (> 1,3 m/s). Se determinó la frecuencia relativa (%) de adultos mayores que cumplen con cada cuadrante establecido. Resultados El umbral fue sobrepasado por el 100% de los participantes (actividades cotidianas básicas). Cerca del 80% de los participantes presenta un Espacio de Clasificación Funcional bajo el límite de referencia (actividades cotidianas instrumentales y avanzadas). El 81% de las mujeres y el 69% de los hombres, se encuentran dentro del Espacio de Clasificación Funcional "eficiente en la comuni-dad". El 31% de los hombres y el 14% de las mujeres alcanzan el valor mínimo para el "cruce efectivo de calles" (actividades coti-dianas avanzadas). Conclusiones La exploración de Espacios de Clasificación Funcional según de velocidad de marcha confortable y máxima aplicada a un grupo de adultos mayores clasificados como autovalentes, resulta en individuos con riesgo para desarrollar actividades instrumentales y avanzadas.

Efeito do treinamento de força com diferentes velocidades de movimento sobre a capacidade funcional e qualidade de vida em idosos: uma revisão sistemática / Effect of resistance training with different movement speeds on functional capacity and quality of life in elderly: a systematic review

Uma das alternativas para manter o idoso ativo a fim de melhorar as capacidades funcionais e a qualidade de vida (QV) é o treinamento de força (TF). Porém, existem variáveis que devem ser consideradas na prescrição do TF como a velocidade de movimento. O objetivo do presente estudo foi realizar uma revisão sistemática para verificar o impacto de programas de TF realizados com diferentes velocidades de movimento na capacidade funcional e qualidade de vida em idosos saudáveis. Após seleção de artigos nas bases de dados Pubmed, Scopus e Web of Science foram encontrados 282 artigos, contudo, após a aplicação dos critérios de inclusão e exclusão foram considerados elegíveis 13 artigos para a revisão. Desses, 10 evidenciaram melhora na funcionalidade do grupo treinamento de força em alta velocidade (TFAV) ou resultado similar comparado ao treinamento tradicional (TT), dois encontraram resultados inalterados para ambos os grupos e um indicou que o grupo TT teve melhoras nos testes funcionais comparado ao TFAV. Quanto à QV, somente dois artigos avaliaram esta variável e foi observado resultado positivo utilizando o TFAV. Assim, foi observado que grande parte dos estudos sugere a realização do TFAV em detrimento do TT visando melhora ou manutenção da funcionalidade e QV. (AU)

One of the alternatives to keep the elderly active in order to improve functional capacities and quality of life (QL) is resistance training (RT). However, there are variables that should be considered in the prescription of RT as the speed of movement. The aim of the present study was to carry out a systematic review to verify the impact of RT programs carried out with different movement speeds on functional capacity and quality of life in healthy elderly people. After selecting articles in the Pubmed, Scopus and Web of Science databases, 282 articles were found, however, after applying the inclusion and exclusion criteria, 13 articles were considered eligible for review. Of these, 10 showed improvement in the functionality of the high-speed resistance training group (HSRT) or similar result compared to traditional training (TT), two found results unchanged for both groups and one indicated that the TT group had improvements in functional tests compared to HSRT. As for QL, only two articles evaluated this variable and a positive result was observed using HSRT. Thus, it was observed that most studies suggest the performance of HSRT at the expense of TT in order to improve or maintain functionality and QL. (AU)

RESUMO Objetivo analisar a relação entre insuficiência familiar e a condição e os marcadores de fragilidade física de idosos acompanhados em ambulatório de Geriatria e Gerontologia. Método estudo quantitativo e transversal realizado com 384 idosos (≥ 60 anos) selecionados por critérios pré-estabelecidos de inclusão e exclusão. Avaliaram-se a fragilidade física segundo o fenótipo da fragilidade e a insuficiência familiar pelo APGAR de Família. Analisaram-se os dados mediante a estatística descritiva e a análise univariada mediante o teste de qui-quadrado com nível de significância estatístico de p≤0,05. Resultados não houve associação entre insuficiência familiar e fragilidade física (p=0,344), entretanto, observou-se percentual de idosos frágeis com elevada Disfunção Familiar (22,2%) e moderada Disfunção Familiar (19,4%), maior que o observado entre os idosos com boa funcionalidade familiar (12,2%). Entre os idosos frágeis para o marcador "fadiga/exaustão", houve proporcionalidade direta ao grau de Disfunção Familiar e relação estatisticamente significativa ao escore total do APGAR de Família (p=0,001). Conclusão e implicações para a prática a insuficiência familiar no idoso está relacionada a outros fatores intrafamiliares e não exclusivamente à fragilidade física, no entanto, pode-se afirmar que o grau de fragilidade física entre os idosos é diretamente proporcional ao nível de Disfunção Familiar.

ABSTRACT Objective to analyze the relationship between family insufficiency and the condition and the markers of physical frailty of elderly people followed up in a Geriatrics and Gerontology outpatient clinic. Method a quantitative and cross-sectional study conducted with 384 elderly (≥ 60 years) selected by pre-established inclusion and exclusion criteria. Physical frailty was assessed according to the frailty phenotype and family insufficiency by the Family APGAR. Data was analyzed using descriptive statistics and univariate analysis using the chi-square test with a statistical significance level of p≤0.05. Results there was no association between family insufficiency and physical frailty (p=0.344), however, it was observed a percentage of frail elderlies with high Family Dysfunction (22.2%) and moderate Family Dysfunction (19.4%), higher than that observed among the elderly with good family functioning (12.2%). Among the frail elderly for the marker "fatigue/exhaustion", there was a direct proportionality to the degree of Family Dysfunction and a statistically significant relation to the total score of the Family APGAR (p=0.001). Conclusion and implications for the practice family frailty in the elderly is related to other intra-family factors and not exclusively to physical frailty, however, it can be stated that the degree of physical frailty among the elderly is directly proportional to the level of Family Dysfunction.

Prevalence of Frailty in Patients Undergoing Cardiac Valve Surgery: Comparison of Frailty Tools

Abstract Background There is no consensus among tools for assessing frailty. Objective To evaluate the prevalence of frailty according to different tools in patients referred for elective valve cardiac surgery. Methods This is a cross-sectional study. All patients were ≥ 18 years of age, clinically stable. The following patients were excluded: those unable to perform the tests because of physical, cognitive, or neurological limitations; those requiring non elective/emergency procedures or hemodynamic instability. During the preoperative cardiology visit, frailty was assessed by the Short Physical Performance Battery (SPPB), the Frailty Deficit Index (FDI), handgrip strength, and gait speed 3m. For the entire analysis, the statistical significance was set at 5%. Results Our cohort consisted of 258 subjects. From the total cohort, 201 were ≤ 70 years of age (77.9%), the predominant etiology according to rheumatic disease (50.7% vs 8.8%; p=0.000) with double mitral lesion (24.9% vs 0%; p=0.000). Frailty was present in 32.9% according SPPB, 29.1% with reduced muscular strength. and 8.9% with FDI. Handgrip strength was weaker in elderly patients (26.7 vs 23.6; p=0.051) and gait speed was lower in the younger group, in which 36% were considered frail (36% vs 14%; p=0.002). Variables associated with frailty were age ≥ 70 years, female gender, aortic stenosis, and regurgitation. Conclusion Frailty in adult patients who will have elective heart valve surgery is present even in the younger groups, although the older group with comorbidities are more frail. Frailty was more clearly shown by the SPPB than by the FDI and handgrip tests.

Correlaciones entre el test de velocidad en 4 metros y el test de caminata en 6 min en enfermos respiratorios crónicos / Correlations between the 4 meter speed test and the 6-minute walking test in chronic respiratory patients

Resumen La prueba de velocidad de marcha en 4 metros (T4M) es considerada sustituto de la caminata en 6 min (TC6M) en EPOC. Sin embargo, no ha sido bien investigada en otras enfermedades respiratorias. Durante un año estudiamos pacientes que concurrieron a nuestra Unidad para realizar el TC6M midiendo la velocidad alcanzada en 4 metros, 2 h previo a realizar el TC6M. De 162 pacientes 99 eran mujeres. La edad media fue de 65 años, peso de 73 kg, talla de 158 cm, IMC 29,4 kg/m2. 36% tenían fibrosis pulmonar idiopática, 17% EPOC, GOLD IV,11% EPOC, GOLD III, 12% apnea de sueño y 12% otras enfermedades. No hubo diferencia para los distintos diagnósticos en ambos tests. La distancia media en TC6Mfue 368,5 m la velocidad: 1,01 m/s en T4M.Hubo una correlación positiva significativa entre ambos test: alto rendimiento en T4M es equivalente a un alto rendimiento en el TC6M. Hubo correlación negativa con la edad y positiva con la estatura. Al año de seguimiento 16 pacientes habían fallecido, siendo estos los que habían obtenido los más bajos rendimientos en ambos tests (T4M: 0,69 m/s y 248,1 m en TC6M) La posibilidad de sobrevida cayó a 20% en aquellos individuos que alcanzaron una velocidad inferior a 0,69 m/s. Es posible sustituir el TC6M por el T4M en pacientes con diferentes patologías respiratoria, podemos predecir la muerte por cualquier causa si un sujeto camina a una velocidad ≤ 0,69 m/s, T4M es barato y fácil de realizar en atención primaria, sirviendo como evaluación de riesgo para referir a un centro más complejo.

4-Meter Gait Speed Test (4MGST) a frailty test, is considered a surrogate for the 6-Minute Walk Test (6MWT) in COPD. However, it has not been investigated in other respiratory conditions. Over a year, we studied patients attending our Unit for evaluation with 6MWT, measuring the speed they achieved walking 4 m, 2 h before performing 6MWT. 162 patients (99 women) were studied; series' mean values were: age 65 years-old; body weight, 73 kg; height, 158 cm and BMI, 29.4 kg/m2. 36% of them had idiopathic pulmonary fibrosis, 17% GOLD IV COPD, 11% GOLD III COPD, 12% pulmonary arterial hypertension, 12% obstructive apnea-hypopnea syndrome, and 12% other conditions. ANOVA showed no difference between diagnostic categories for both test. Average score in 6MWT was 368.5 m and 1.01 m/s in 4MGST. Pearson correlation coefficient revealed significant positive correlation between results of both tests: high score in 4MGST is equivalent to high score in 6MWT. There was negative correlation with age and positive correlation with height. At one year follow-up, 16 patients had died. They obtained significantly lower scores in both tests (4MGST: 0.69 m/s and 6MWT: 248.1 m) Survival chance fell to 20% for patients walking slower than 0.69 m/s. It is possible to replace TC6M with T4M in patients with different respiratory pathologies, we can predict death for any cause if a subject walked at ≤ speed at 0.69 m/s. T4M is cheap and easy to perform in primary care, serving as a risk assessment to refer to a more complex center.

Efeitos do método pilates sobre a capacidade funcional, fatores antropométricos, marcadores inflamatórios e qualidade de vida em idosas sedentárias / Effects of the pilates method on functional capacity, anthropometric factors, inflammatory markers and quality of life in sedentary elderly women

O objetivo do presente estudo foi investigar os efeitos de exercícios físicos baseados no método Pilates solo sobre a capacidade funcional, fatores antropométricos, níveis de marcadores inflamatórios circulantes e a qualidade de vida em idosas sedentárias. Trata­se de um delineamento quase experimental com pré e pós teste. A amostra foi constituída por 33 mulheres idosas com idade igual ou superior a 60 anos. Para avaliar a capacidade funcional (CF) foram utilizados os testes de velocidade de caminhada (VC) e de força de preensão manual (FPM). Para avaliar a presença de marcadores inflamatórios foram realizados exames laboratoriais a fim de quantificar os níveis séricos de proteína C reativa ultrassensível (PCR-us) e fibrinogênio. E para avaliar a qualidade de vida (QV) foi utilizado o questionário SF ­ 36. Na análise estatística utilizou-se o teste de normalidade Shapiro Wilk. Para os dados paramétricos teste t pareado e ANOVA one Way e, para os dados não paramétricos, o teste Wilcoxon e Kruskal-Wallis. O teste Qui-Quadrado foi utilizado para analises de associações. Os dados foram analisados pelo no programa SPSS-IBM, versão 22.0 devidamente registrado. O nível de significância adotado foi de p≤0,05. O grupo Pilates não apresentou alterações estatisticamente significativas em relação à CF (p>0,05), porém as demais variáveis apresentaram diferença significativa. Para variáveis antropométricas, PCR e fibrinogênio (p < 0,05); e QV, dois domínios apresentaram alterações significativas: limitações por aspectos físicos (p=0,045) e dor (p=0,011). Conclui-se que a prática do método Pilates solo promoveu redução significativa sobre a composição corporal, sobre os níveis séricos de marcadores inflamatórios, sobre a qualidade de vida e manutenção da capacidade funcional de idosas sedentárias. (AU)

The aim of the present study was investigate the effects of exercises based on the Pilates method on functional capacity, anthropometric factors, levels of circulating inflammatory markers and quality of life in sedentary elderly women. It is an almost experimental design with pre and post-test. The sample considered of 33 elderly individuals, aged 60 years and female. In order to evaluate the functional capacity (FC), the tests of walking speed (WS) and manual grip strength (MGS) were used; to evaluate the presence of inflammatory markers, laboratory tests were performed to quantify the serum levels of C-reactive protein and fibrinogen, and the SF-36 questionnaire was used to evaluate the quality of life. For statistical analysis, Shapiro Wilk normality test was used. For parametric data, paired t- test and one-way ANOVA were used, and for nonparametric data, the Wilcoxon and Kruskal -Wallis test. Chi-square test was used for association analysis. All data were analyzed by SPSS-IBM, version 22.0 duly registered and the significance level of p ≤0.05 was stipulated. The Pilates group did not present significant alterations in relation to CF (p> 0.05), but the other variables presented. Anthropometric variables (total body mass, BMI, waist and hip circumference), C-reactive protein and fibrinogen (p< 0,05); and in relation to QV, two domains presented significant changes: limitations by physical aspects (p = 0.045) and pain (p = 0.011). It was concluded that the Pilates solo practice promoted a significant reduction in body composition, serum levels of inflammatory markers, quality of life and maintenance of functional capacity

Changes in executive function and gait in people with mild cognitive impairment and Alzheimer disease / Alterações na função executiva e na marcha em pessoas com comprometimento cognitivo leve e doença de alzheimer

ABSTRACT. Changes in executive function and motor aspects can compromise the prognosis of older adults with mild cognitive impairment (MCI) and favor the evolution to dementia. Objectives: The aim of this study was to investigate the changes in executive function and gait and to determine the association between changes in these variables. Methods: A 32-month longitudinal study was conducted with 40 volunteers: 19 with preserved cognition (PrC), 15 with MCI and 6 with Alzheimer disease (AD). Executive function and gait speed were assessed using the Frontal Assessment Battery, the Clock-Drawing test and the 10-meter walk test. For data analysis, the Pearson product-moment correlation, two-way repeated-measures ANOVA, and chi-square were conducted. Results: After 32 months, an improvement in the executive function was found in all groups (p=0.003). At baseline, gait speed was slower in individuals with MCI and AD compared to those with PrC (p=0.044), that was maintained after the follow-up (p=0.001). There was significant increase in number of steps in all groups (p=0.001). No significant association was found between changes in gait speed and executive function. Conclusions: It should be taken into account that gait deteriorates prior to executive function to plan interventions and health strategies for this population.

RESUMO. Alterações na função executiva e nos aspectos motores podem comprometer o prognóstico de idosos com comprometimento cognitivo leve (CCL) e favorecer a evolução para demência. Objetivos: O objetivo deste estudo foi investigar alterações na função executiva e na marcha e determinar a associação entre alterações nessas variáveis. Método: Foi realizado um estudo longitudinal de 32 meses com 40 voluntários: 19 com cognição preservada (PrC), 15 com CCL e 6 com doença de Alzheimer (DA). A função executiva e a velocidade da marcha foram avaliadas por meio de bateria de avaliação frontal, do teste de desenho do relógio e do teste de caminhada de 10 metros. Para a análise de dados, o coeficiente de correlação produto-momento de Pearson, ANOVA de medidas repetidas bidirecional e o qui-quadrado foram realizados. Resultados: Após 32 meses, houve melhora na função executiva em todos os grupos (p=0,003). No início do estudo, a velocidade da marcha foi mais lenta nos indivíduos com CCL e DA em comparação com os PrC (p=0,044), que foi mantida após o acompanhamento (p=0,001). Houve aumento significativo no número de etapas em todos os grupos (p=0,001). Não foi encontrada associação significativa entre alterações na velocidade da marcha e função executiva. Conclusões: Deve-se levar em consideração que a marcha se deteriora antes da função executiva para planejar intervenções e estratégias de saúde para essa população.

Muscle function, physical function, and gait in older women with and without knee osteoarthritis

Abstract Aim: To compare muscle function of knee extensors, gait parameters, and physical function in older women with and without knee osteoarthritis (KOA) and to associate these parameters to the KOA incidence in this population. Methods: Sixteen older women with KOA (66.9 ± 5.5 years; 74.9 ± 10.0 kg; 157.9 ± 0.9 cm; 30.2 ± 5.0 kg/m2) and fourteen healthy counterparts (control group: CG; 68.8 ± 5.8 years; 68.9 ± 10.5 kg; 158 ± 0.06 cm; 27.4 ± 4.0 kg/m2) participated in this study. Muscle function, physical function, and gait parameters were evaluated in both groups. The Western Ontario and McMaster Index (WOMAC) questionnaire was answered only by the KOA group. A correlation was performed to verify if KOA incidence was associated with muscle function, physical function, and gait parameters. Results: KOA group showed lower peak torque at 60°/s (30%; p = 0.003) and 180°/s (37%; p < 0.001), greater acceleration time at 60°/s (382%; p < 0.001), lower cadence (12.2%; p = 0.002), slower gait speed (19.5%; p < 0.001) and greater stride time (12.5%; p = 0.001) than CG group. However, there was no difference between groups in physical function (p < 0.0045). The KOA incidence presented a negative correlation with peak torque (rho = −0.602; p < 0.001), cadence (rho = −0.533; p = 0.002), gait speed (rho = −0.633; p < 0.001), stride length (rho = −0.517; p = 0.003) and a positive correlation with stride time (rho = 0.533; p = 0.002) and acceleration time (rho = 0.655; p < 0.001). Conclusion: Our findings suggest that knee osteoarthritis may impair the function of the knee extensors muscles and gait parameters. An association between the ability to produce force rapidly and gait speed with the KOA incidence in older women was also observed.

Effects of a backward running training on backward peak velocity running, V̇O2max, vVO2max and 3 km forward running performance in male adults: a pilot study

Abstract Aims: The study aimed to evaluate the effects of a backward running (BR) training program prescribed by the peak backward running velocity (Vpeak_BR) on physiological variables and a 3 km forward running (FR) performance. Methods: Eight untrained running male adults in running took place in the study. All the participants underwent five weeks of BR training prescribed based on Vpeak_BR. They performed a maximal incremental test on the treadmill to determine the maximal oxygen uptake (V̇O2max) and the velocity associated with V̇O2max (vV̇O2max). The participants were also tested on the track field to determine the Vpeak_BR and undertook a 3 km FR performance. All initial assessments were also performed after the training period. Results: The results showed statistically significant improvements in 3 km FR performance (14.2 ± 1.2 min vs. 13.5 ± 1.0 min) and Vpeak_BR (8.0 ± 0.8 km·h−1 vs. 8.5 ± 0.5 km·h−1) after the training period. Conclusion: BR training effectively improved 3 km FR performance and Vpeak_BR, demonstrating that Vpeak_BR determined according to the protocol proposed in this study can be used for the prescription of BR training. Further, BR training represents an effective training method that can be inserted into an FR running training program.

Associação entre cognição, velocidade da marcha e habilitação veicular em idosos / Relación entre cognición, velocidad de la marcha y licencia de conducir en adultos mayores / Association between cognition, gait speed and vehicle habilitation in elderly people

Resumo Objetivo: Investigar a associação entre cognição, velocidade da marcha e resultado final da habilitação veicular de idosos candidatos à Carteira Nacional de Habilitação. Métodos: Estudo quantitativo de corte transversal desenvolvido em 12 clínicas de trânsito de Curitiba/Paraná/Brasil. A amostra do tipo probabilística foi constituída por 421 idosos (≥ 60 anos). Para a coleta de dados foram aplicados o Mini-Exame do Estado Mental (MEEM), teste de velocidade da marcha e realizadas consultas ao formulário Registro Nacional de Condutores Habilitados. A relação entre as variáveis foi identificada por meio do teste de regressão linear múltipla, método stepwise, utilizando-se o programa estatístico R versão 3.4.0. Resultados: Observou-se que, ao aumentar o escore no MEEM em uma unidade a chance do idoso ser considerado inapto temporariamente para dirigir diminui em 54,96% (95%; IC 28,47% - 92,69%; p<0,0001), e ao aumentar uma unidade no escore do MEEM houve um aumento na velocidade da marcha (VM) de 0,0091 (95%; IC 0,0005 - 0,0174; p=0,0366). Conclusão: O elevado escore no MEEM diminuiu a probabilidade do idoso ser considerado inapto temporariamente para dirigir veículos automotores e houve uma tendência de aumento da VM com o aumento dos escores do MEEM. A VM é um importante indicador a ser avaliado em idosos motoristas, logo, é um tópico a ser incluído nas avaliações das clínicas de trânsito, assim como o rastreamento cognitivo, fundamental para avaliar um conjunto de atividades mentais necessárias à direção veicular segura.

Conclusión: La puntuación del MEEM elevada redujo la probabilidad de que el adulto mayor sea considerado no apto temporalmente para conducir automóviles y hubo una tendencia de aumento de la VM con un aumento de la puntuación del MEEM. La VM es un indicador importante que debe ser evaluado en adultos mayores conductores. Por lo tanto, es un tema que deberá ser incluido en las evaluaciones de los centros médicos de evaluación de tránsito, así como también el rastreo cognitivo, fundamental para analizar un conjunto de actividades mentales necesarias para una conducción vehicular segura.

Abstract Objective: To investigate the association between cognition, gait speed and the result of vehicle habilitation of elderly candidates for the National Driver's License. Methods: Quantitative cross-sectional study developed in 12 traffic agencies in Curitiba, state of Paraná, Brazil. The probabilistic sample consisted of 421 elderly people (≥ 60 years). The Mini-Mental State Examination (MMSE), gait speed testing and consultations to forms of the National Qualified Drivers Registration were used for data collection. The relationship between variables was identified through the multiple linear regression test, stepwise method, using the statistical program R, version 3.4.0. Results: When increasing a unit in the MMSE score, the chance of the elderly person being considered as temporarily unfit to drive decreased by 54.96% (95% CI; 28.47% - 92.69%I; p<0.0001). When increasing a unit in the MMSE score, there was an increase in gait speed (GS) of 0.0091 (95% CI: 0.0005 - 0.0174; p=0.0366). Conclusion: The high MMSE score decreased the probability of the elderly participant being considered temporarily unfit to drive motor vehicles. There was a trend of higher GS with the increase in MMSE scores. As GS is an important indicator to be assessed in elderly drivers, this topic should be included in evaluations of traffic agencies, as well as cognitive screening, which is essential to assess a set of mental activities necessary for safe driving.

Differences of body composition and physical strength among Japanese and Thai older adults living in Chiang Mai, Thailand: an inter-ethnic cross-sectional study

BACKGROUND@#The number of adults aged over 65 years is rapidly increasing in several Southeast Asian countries. Muscle mass decreases with age, leading to sarcopenia. The primary objective of this study was to determine whether differences exist in the body composition and physical strength, according to ethnicity, among community-dwelling Japanese and Thai older adults living in Chiang Mai Province, Thailand.@*METHODS@#A survey was conducted in February and March 2019. Japanese and Thai adults aged ≥ 60 years living in Chiang Mai Province were recruited through community clubs. Participants completed a self-administered questionnaire that enabled collection of data on age, sex, educational background, marital status, annual income, current medical conditions, smoking and alcohol consumption, and exercise habits. Measurements were collected on height, weight, body composition, blood pressure, hand grip, and walking speed for 6 m. Body composition was measured using a standing-posture 8-electrode multifrequency bioimpedance analysis analyzer. Hand grip of each hand was measured with the patient in the standing position using a digital grip dynamometer. Multivariable logistic regression was used to determine factors associated with skeletal muscle mass index (SMI).@*RESULTS@#Of the total 119 participants, 47 were Japanese (26 men, 21 women) and 72 were Thai (16 men, 56 women). The prevalence of a low SMI was 3/26 (12%), 1/21 (5%), 6/16 (38%), and 5/56 (9%) among Japanese men, Japanese women, Thai men, and Thai women, respectively. The prevalence of low muscle strength was 2/26 (8%), 2/21 (10%), 3/16 (19%), and 13/56 (23%) among Japanese men, Japanese women, Thai men, and Thai women, respectively. There were significant differences between ethnic groups in body mass index for both sexes, percentage body fat in women, SMI in men, and average grip strength in men. Ethnic group, sex, age, and body mass index were independent predictors of SMI.@*CONCLUSIONS@#Ethnicity had a clinically important effect on body composition and physical strength among older Japanese and Thai adults living in a similar environment.

Predictors of walking speed in older people after stroke / Preditores da velocidade de marcha em idosos comunitários pós acidente vascular encefálico

Introdução: as medidas de desempenho da função física podem prever incidência futura de incapacidade, dependência em atividades de vida diária, institucionalização e morte em idosos após Acidente Vascular Encefálico. Embora existam estudos verificando o efeito da idade na velocidade de marcha e na incapacidade, ainda existem lacunas significativas na literatura com idosos após Acidente Vascular Encefálico. Objetivo: verificar quais são os possíveis preditores da velocidade de marcha em idosos após Acidente Vascular Encefá- lico. Métodos: estudo transversal, em que foi avaliada: velocidade de marcha (teste de caminhada de 10 metros ­ TC10m), força de flexores plantares e extensores de joelho do lado parético (Teste do Esfigmomanômetro Modificado ­ TEM), mobilidade (Time up and Go ­ TUG) e depressão (Escala de Depressão Geriátrica ­ GDS). Foi utilizada a regressão linear para verificar quais preditores explicariam a velocidade de marcha. Resultados: 60 indivíduos foram incluídos, idade média de 71 ± 7 anos, com TC10m de 0,7 ± 0,3 m/s, força de flexores plantares de 133 ± 66 mmHg e força de extensores de joelho de 198 ± 62 mmHg, TUG de 19 ± 10 s e GDS 6 ± 3 pontos. A força de flexores plantares do lado parético explicou 33% da variação da velocidade de marcha. Quando a mobilidade foi incluída, a variância aumentou para 43%. Conclusão: a força dos flexores plantares do lado parético e a mobilidade são preditores e influenciam diretamente a velocidade de marcha nos idosos após o Acidente Vascular Encefálico.(AU)

Introduction: performance-based measures of physical function can predict the future incidence of disability, dependence in activities of daily living, institutionalization, and death in older people after stroke. Although there have been previous studies examining the effect of age on walking speed and disability, significant gaps still exist in the literature with older people after stroke. Purpose: to verify the possible predictors of the walking speed in elderly individuals after stroke. Methods: cross-sectional study, where it was evaluated: walking speed (10-meter walking test ­ 10 MWT), plantar flexor and knee extensor strength of the paretic side (Modified Sphygmomanometer Test ­ MST), mobility (Time up and Go ­ TUG), and depression (Geri- atric Depression Scale ­ GDS). It was used linear regression to verify which predictors would explain the walking speed (α=0,05). Results:60 individuals were included with a mean age of 71±7 years, with 10MWT of 0.7±0.3m/s, plantar flexor strength of 133±66mmHg and knee extensor strength of 198±62mmHg, TUG of 19±10s, and GDS 6±3 points. The plantar flexor strength of the paretic side explained 33% of the variance of the walking speed. When mobility was included, variance increased to 43%. Conclusion: plantar flexors strength of the paretic side and mobility are predictors and have a direct influence on the walking speed in older people after stroke.(AU)

Therapeutic effects of virtual reality video gaming on functional mobility, balance, and gait speed in individuals with tropical spastic paraparesis: A randomized crossover clinical trial

Abstract INTRODUCTION: Individuals with human T-cell lymphotropic virus 1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) experience sensorimotor alterations, which can affect functional performance. Virtual reality (VR) videogaming is a therapeutic option, though there is scarce evidence for its use in this population. We aimed to investigate the therapeutic effects of a VR video game on functional mobility, balance, and gait speed in individuals with HAM/TSP. METHODS: We conducted a blinded, crossover clinical trial comprising 29 individuals with HAM/TSP and randomized them into two groups: (1) early therapy: rehabilitative protocol started immediately after the initial evaluation and (2) late therapy: rehabilitative protocol started 10 weeks later. We assessed all participants for balance using the Berg Balance Scale (BBS) scores, functional mobility using the Timed Up and Go (TUG) test, and gait speed using video camera and CvMob software. Differences were considered significant if p<0.05. RESULTS: The early therapy group individuals presented with higher BBS scores (p=0.415), less TUG times (p=0.290), and greater gait speed (p=0.296) than the late therapy group individuals. CONCLUSIONS: VR videogaming is a useful option for rehabilitative therapy in individuals with HAM/TSP; it positively affects balance, functional mobility, and gait speed.

Concordância na velocidade da marcha de mulheres diabéticas tipo 2 em diferentes testes de caminhada / Agreement in the gait speed of type 2 diabetic women from different walking tests

O objetivo desse estudo foi verificar a concordância na velocidade da marcha (VM) a partir dos testes de caminhada de seis minutos (6MWT) e de quatro metros (4MWT) em mulheres diabéticas tipo 2 (DM2). Os testes foram realizados antes e após intervenção de 12 semanas com exercícios físicos. O 4MWT foi realizado em espaço de quatro metros, sendo o resultado do teste medido como o tempo gasto (segundos) no percurso. O 6MWT foi realizado em modelo de ir e vir em uma distância de 15 metros e o resultado foi a distância total (metros) percorrida. Os resultados foram padronizados para velocidade de deslocamento (m/s). Para avaliar a concordância (6MWTpré x 4MWTpré) e (6MWTpósx 4MWTpós), utilizou-se o teste de Bland-Altman (B-A) e o coeficiente de concordância de correlação de Lin. O nível de significância aceito para o estudo foi α 5%. Foram medidas 39 mulheres, com idade média de 58,79 ± 10,03 anos e diagnóstico de DM2 a 8,64 ± 8,53 anos. Verificou-se, pelo teste de B-A, diferenças na VM dos testes de -0,001 ± 0,19 m/s (IC95%: -0,37 a 0,37 m/s) no início e 0,02 ± 0,21 m/s (IC95%: -0,39 a 0,42 m/s) ao final e concordância de 0,60 (IC95%: 0,41 a 0,79; p < 0,001) e 0,52 (IC95%: 0,31 a 0,73; p < 0,001) pré e pós, respectivamente, pelo coeficiente de concordância de correlação Lin. Através dos dados obtidos, sugere-se que os dois testes podem ser utilizados para avaliar a VM das mulheres DM2, porém o 6MWT apresentou maior reprodutibilidade para detectar mudanças na VM ao longo do tempo

This study aimed to test the agreement in the gait speed (GS) between the 6-minute walk test and the 4-me-ter gait speed (6MWT - 4MWT) in type 2 diabetic women (T2DM). The tests were performed before and after a 12-week physical exercise intervention. The 4MWT was performed in a space of four meters, with results based on the time spent (seconds) to complete a 4-meter distance. The 6MWT was carried out similar to a yo-yo test in 15 meters and the result was operationalized by the total distance (meters) covered. The results of the tests were standardized as speed (m/s). To evaluate agreements (6MWTbefore x 4MWTbefore) and (6MWTafter x 4MWTafter), Bland-Altman (B-A), and Lin's agreements were used. The level of significance was set at 5%. A total of 39 women were evaluated, mean age 58.79 ± 10.03 years, diagnosis of diabetes at 8.64 ± 8.53 years.The B-A test showed a mean difference in GS of -0.001 ± 0.19 m/s (95%CI: -0.37 to 0.37 m/s) before and 0.02 ± 0.21 m/s (95%CI: -0.39 to 0.42 m/s) after, and Lin's agreements of 0.60 (95%CI: 0.41 to 0.79; p < 0.001) and 0.52 (95%CI: 0.31 to 0.73; p < 0.001) before and after, respectively. Based on our data it is suggested that the two tests can be used to evaluate the GS of T2DM women, but the 6MWT was more reproductible to detect changes in GS over time

Speed and heart rate variation during marathon running in a hot environment / Variación de la velocidad y la frecuencia cardiaca durante un maratón en un ambiente caluroso

Abstract The purpose of the study was to analyze the variation of running speed and heart rate in amateur runners during a marathon in a hot environment. Eighteen runners (weight: 65.2 ± 12.21 kg, height: 168.4 ± 10.6 cm, VO2max: 52.9 ± 7.1 ml/kg/min) took part of a beach-side marathon (42195 m) under a temperature of 27.8 ± 3.52 ºC and at 0-80 m altitude. Pearson's correlation showed a significant linear relationship between the increase in thermal stress index (WGBT) and the speed variation (r= 0.168, p= 0.049). In this respect, the total duration of the race revealed a direct relationship with speed (r= 0.675, p= 0.003) and heart rate (r= 0.631, p= 0.007) variation. Multiple regressions analysis showed that 61.6% of the final race time was explained by the speed variation in the 26 to 30 km course section (r 2 = 0.61; F= 26.17; p< 0.001) and 37% by the heart rate variation in the 31 to 35 km section (r 2 = 0.37; F= 10.38; p< 0.001). In conclusion, an increase in the environmental temperature provoked a decrease in running pacing, with a stronger effect in the second half of the race. Therefore, coaches should take these aspects into account in training and strategies to mitigate the impact of these conditions on the physical and physiological performance of amateur runners.

Resumo O presente estudo teve como objetivo analisar a variação da velocidade da corrida e a frequência cardíaca em corredores amadores durante uma maratona em um ambiente de alto índice térmico. Dezoito corredores amadores (peso: 65,2 ± 12,21 kg, altura: 168,4 ± 10,6 cm, VO2max: 52,9 ± 7,1 ml/kg/min) correram uma maratona (42195 m) em proximidade ao mar, sob um índice térmico de 27,8 ± 3,52 ºC e com percurso de 0-80 metros acima do nível do mar. O teste de Pearson apresentou uma correlação significativa entre o aumento do índice de estresse térmico (IBUTG) e a variação da velocidade (r= 0,168, p= 0,049). Neste sentido, a duração total da corrida apresentou uma relação direta com a velocidade (r= 0,675, p= 0,003) e a variação da frequência cardíaca (r= 0,631, p= 0,007). O tempo final da corrida se interpretou em 61,6% e 37% pela variação da velocidade de 26 a 30 km (r 2 = 0,61; F= 26,17; p< 0,001) e pela variabilidade da frequência cardíaca no lapso de 31 a 35 km (r 2 = 0,37; F= 10,38; p< 0,001), respectivamente. Em suma, o índice térmico provoca uma diminuição no ritmo da velocidade, sendo esse efeito maior na segunda metade da corrida. Devido a isso, os preparadores devem planejar treinamentos e estratégias para mitigar o impacto dessas condições no desempenho físico e fisiológico dos corredores amadores.

Resumen El objetivo del presente estudio fue analizar la variación de la velocidad de carrera y la frecuencia cardíaca en corredores aficionados durante un maratón en un entorno de alto índice térmico. Dieciocho corredores aficionados (peso: 65.2 ± 12.21 kg, altura: 168.4 ± 10.6 cm, VO2max: 52.9 ± 7.1 ml/kg/min) corrieron un maratón (42 195 m) en cercanía al mar bajo un índice térmico de 27.8 ± 3.52ºC y con recorrido de 0-80 m.s.n.m. La prueba de Pearson mostró una correlación significativa entre el aumento del índice de estrés termal (TGBH) y la variación de la velocidad (r = 0.168, p = 0.049). En este sentido, la duración total de la carrera presentó una relación directa con la velocidad (r = 0.675, p = 0.003) y la variación de la frecuencia cardíaca (r= 0.631, p = 0.007). El tiempo final de carrera se explicó en un 61.6% y 37% por la variación de la velocidad de 26 a 30 km (r 2 = 0.61; F = 26.17; p < 0.001) y por la variabilidad de la frecuencia cardíaca en el lapso de 31 a 35 km (r 2 = 0.37; F= 10.38; p < 0.001) respectivamente. En conclusión, el índice térmico provoca una disminución en el ritmo de la velocidad, este efecto mayor en la segunda mitad de la carrera. Por lo anterior, entrenadores deben planificar entrenamientos y estrategias para mitigar el impacto de estas condiciones en el desempeño físico y fisiológico de los corredores amateur.

Auto reporte de la velocidad de marcha y su asociación con marcadores de adiposidad y riesgo cardiovascular en Chile / Association of self-reported walking speed with markers of adiposity and cardiovascular risk in Chile

Background Walking speed is a strong predictor of non-communicable diseases and mortality. Aim To investigate the association of self-reported walking pace with adiposity, metabolic and cardiovascular markers in the Chilean population. Material and Methods Analysis of data from 5,077 participants of the 2009-2010 National Health Survey (ENS 2009-2010). Walking speed was self-reported as average or slow pace. Body mass index (BMI), waist circumference (WC), blood pressure, blood glucose, glycosylated hemoglobin and lipid profile were the outcome. Results In Chile, 11% (95% confidence intervals [CI]: 10.0; 12.7) of the population reported a slow walking pace. Compared with average walking people, those reporting a slow pace had a higher body weight (difference (∆) 5.65 kg [95% CI: 3.22; 8.09], p < 0.01), BMI (D 2.48 kg/m 2 [95% CI: 1.53; 3.44], p < 0.01), WC (D 6.23 cm [95% CI: 4.12; 8.34], p < 0.01), serum triglycerides (D 30,9 mg/dl [95% CI: 5,31; 57,5], p = 0.018), and lower HDL cholesterol (D -2.32 mg/dl [95% CI: -4,24; -0,34], p = 0.022). Those reporting a slow pace had also a higher odd of being obese (odds ratio (OR): 2.46 [95% CI: 1.82; 3.33], p < 0.01), being diabetic (OR: 1.54 [95% CI: 1.02; 2.40], p = 0.018) and having metabolic syndrome (OR: 2.03 [95% CI: 1.30; 3.18], p = 0.002). Conclusions In Chilean adults, slow walking pace is associated with and unfavorable adiposity and lipid profile, including a higher probability of being obese, diabetic and having metabolic syndrome.

Sintomas depressivos e funcionalidade em idosos da atenção primária de Porto Alegre (RS) / Depressive symptoms and functionality in older adults of the Porto Alegre's Primary Care

OBJETIVO: Determinar a prevalência de sintomas depressivos (SD) e a sua relação com aspectos funcionais, sociodemográficos e antropométricos em idosos da Estratégia Saúde da Família de Porto Alegre (RS). MÉTODOS: Trata-se de um estudo transversal prospectivo e analítico com amostra aleatória de 509 idosos de 30 unidades básicas de saúde. Analisaram-se idade, faixa etária, sexo, estado civil, escolaridade, peso, altura, índice de massa corporal, funcionalidade, atividades básicas e instrumentais de vida diária e presença de SD. Para análise estatística, utilizou-se o teste χ2 (bivariada) e de regressão logística (multivariada). RESULTADOS: A prevalência de SD na amostra foi de 35,4%. O modelo final apresentou associação estatisticamente significativa de SD com sexo feminino (odds ratio ­ OR = 2,87; intervalo de confiança de 95% ­ IC95% 1,92­9,23), analfabetismo [(OR = 2,13; IC95% 1,89­5,12), baixa escolaridade (OR = 1,23; IC95% 1,05­2,74), dependência em atividades instrumentais de vida diária (OR = 4,03; IC95% 1,68­9,64), baixos escores no teste senta/levanta (OR = 0,89; IC95% 0,82­0,96) e menor força de preensão manual (OR = 0,95; IC95% 0,93­0,98). CONCLUSÃO: A prevalência dos SD observada foi alta, e, ante as associações apresentadas, sugere-se que mulheres analfabetas ou com baixa escolaridade, com dificuldade em atividades instrumentais de vida diária, mais fracas e lentas devem ser investigadas quanto à presença de SD, pelo risco de desenvolvê-los.

OBJECTIVE: The aim of this study was to determine the prevalence of depressive symptoms (DS) and their relationship with functional, sociodemographic and anthropometric aspects in the older adults from the Family Health Strategy of Porto Alegre/ RS. METHOD: This is a cross-sectional, prospective and analytical study, with a random sample of 509 older adults from 30 public health units. The following variables were analyzed: age, age group, sex, marital status, schooling, weight, height and body mass index, functionality, activities of daily living, both basic and instrumental, and the presence of DS. For the statistical analyses, the bivariate qui-square test and the multivariate logistic regression were used. RESULTS: The prevalence of DS in this sample was 35,5%. The final model presented a significant statistical association of DS with female gender (OR = 2.87; IC95% 19.2-9.23), illiteracy (OR = 2.13; IC95% 1.89­5.12), low schooling (OR = 1.23; IC95% 1.05­2.74), dependence on IADL (OR = 4.03; IC95% 1.68­9.64), low scores in the sit-to-stand test (OR = 0.89; IC95% 0.82­0.96) and lower HGS (OR = 0.95; IC95% 0.93­0.98). CONCLUSION: The prevalence of DS observed was high (35.4%) and, considering the associations presented, it is suggested that illiterate or poorly educated, weaker and slower women with difficulty in IADL should be investigated for the presence of depressive symptoms, for being at the risk of developing them.
