ABSTRACT

Lower limb ankle exoskeletons have been used to improve walking efficiency and assist the elderly and patients with motor dysfunction in daily activities or rehabilitation training, while the assistance patterns may influence the wearer's lower limb muscle activities and coordination patterns. In this paper, we aim to evaluate the effects of different ankle exoskeleton assistance patterns on wearer's lower limb muscle activities and coordination patterns. A tethered ankle exoskeleton with nine assistance patterns that combined with differenet actuation timing values and torque magnitude levels was used to assist human walking. Lower limb muscle surface electromyography signals were collected from 7 participants walking on a treadmill at a speed of 1.25 m/s. Results showed that the soleus muscle activities were significantly reduced during assisted walking. In one assistance pattern with peak time in 49% of stride and peak torque at 0.7 N·m/kg, the soleus muscle activity was decreased by (38.5 ± 10.8)%. Compared with actuation timing, the assistance torque magnitude had a more significant influence on soleus muscle activity. In all assistance patterns, the eight lower limb muscle activities could be decomposed to five basic muscle synergies. The muscle synergies changed little under assistance with appropriate actuation timing and torque magnitude. Besides, co-contraction indexs of soleus and tibialis anterior, rectus femoris and semitendinosus under exoskeleton assistance were higher than normal walking. Our results are expected to help to understand how healthy wearers adjust their neuromuscular control mechanisms to adapt to different exoskeleton assistance patterns, and provide reference to select appropriate assistance to improve walking efficiency.

ABSTRACT

Resumo Fundamento Apesar de avanços em técnicas cirúrgicas e cuidados pós-operatórios em cardiopatia congênita, a morbidade cardiovascular permanece elevada. Objetivo Avaliar a associação do condicionamento pré-operatório de crianças e adolescentes com cardiopatias, mensurado por teste de caminhada de 6-minutos (TC6M) e variabilidade da frequência cardíaca (VFC), com a ocorrência de choque cardiogênico, séptico e morte no período pós-operatório. Métodos Estudo clínico prospectivo e observacional de 81 pacientes de 8 a 18 anos. No período pré-operatório foram realizados o TC6M (distância caminhada e SpO2) e a VFC. O escore de risco ajustado para cirurgia de cardiopatia congênita ( RACHS-1 ) foi aplicado para predizer o fator de risco cirúrgico para mortalidade. A ocorrência de pelo menos uma das complicações citadas foi considerada como evento combinado. Valores de p<0,05 foram considerados significantes. Resultados Dos 81 pacientes, 59% eram do sexo masculino, com idade média de 12 anos; 33% eram cianóticos; e 72% já tinham realizado cirurgias prévias. O choque cardiogênico foi a complicação mais comum, e 31% apresentaram evento combinado. Cirurgia prévia, tipo de cardiopatia atual, RACHS-1 , SpO2 em repouso, durante e após recuperação do TC6M foram selecionados para o estudo multivariado. A SpO2 após o TC6M permaneceu como fator de risco independente para aumentar a ocorrência de evento combinado no pós-operatório (OR: 0,93, IC95% [0,88 - 0,99], p=0,02). Conclusão O SpO2 após o TC6M no período pré-operatório foi o fator independente preditor de prognóstico no pós-operatório em crianças e adolescentes submetidos à correção cirúrgica; a distância caminhada e as variáveis da VFC não tiveram a mesma associação.


Abstract Background Despite advances in surgical technique and postoperative care in congenital heart disease, cardiovascular morbidity is still high. Objective To evaluate the association between preoperative cardiovascular fitness of children and adolescents, measured by the 6-minute walk test (6MWT) and Heart Rate Variability (HRV), and the occurrence of cardiogenic, septic shock and death in the postoperative period. Methods Prospective, observational clinic study including 81 patients aged from 8 to 18 years. In the preoperative period, the 6MWT (distance walked and SpO2) and HRV were performed. The adjusted risk score for surgeries for congenital heart disease (RACHS-1) was applied to predict the surgical risk factor for mortality. The occurrence of at least one of the listed complications was considered as a combined event. P values < 0.05 were considered as significant. Results Of the patients, 59% were male, with mean age of 12 years; 33% were cyanotic; and 72% had undergone previous cardiac surgery. Cardiogenic shock was the most common complication, and 31% had a combined event. Prior to surgery, type of current heart disease, RACHS-1, SpO2at rest, during the 6MWT and recovery were selected for the multivariate analysis. The SpO2at recovery by the 6MWT remained as an independent risk factor (OR 0.93, 95%CI [0.88 - 0.99], p=0.02) for the increasing occurrence of combined events. Conclusion SpO2after the application of the 6MWT in the preoperative period was an independent predictor of prognosis in children and adolescents undergoing surgical correction; the walked distance and the HRV did not present this association.

ABSTRACT

RESUMO A sarcopenia é uma síndrome caracterizada pela perda progressiva de massa muscular e está associada a desfechos adversos na saúde de idosos. A atividade física tem sido apontada como uma importante ferramenta para a prevenção da sarcopenia. Diante disso, este estudo investigou a relação da duração e frequência da prática de atividade física com os indicativos de sarcopenia de idosos. Participaram deste estudo transversal 551 idosos praticantes de atividade física nas academias da terceira idade do município de Maringá (PR). Como instrumentos foram utilizados o international physical activity questionnaire (IPAQ) e o SARC-F. A análise dos dados foi conduzida por meio dos testes de Kolmogorov-Smirnov, correlação de Spearman e a análise de equações estruturais (p<0,05). Os resultados evidenciaram que os idosos deste estudo realizam atividades físicas leves (Md=3) e moderadas (Md=2) semanalmente, mas não praticam atividades vigorosas (Md=0), e apresentam baixo indicativo de sarcopenia (Md=1). A análise de equações estruturais revelou que as variáveis de atividades leves e moderadas apresentaram associação significativa (p<0,05), e negativa com o escore de indicativo de sarcopenia, entretanto fraca (β<0,20), explicando 7% da sua variabilidade. Concluiu-se que a prática de atividades física leves e moderadas parece ser fator interveniente no indicativo de sarcopenia em idosos.

La actividad física ha sido señalada como una importante herramienta para la prevención de la sarcopenia. Por lo tanto, este estudio investigó la relación de la duración y frecuencia de la práctica de actividad física con los indicativos de sarcopenia de ancianos. En este estudio transversal participaron 551 ancianos practicantes de actividad física en las Academias de la tercera edad del municipio de Maringá (PR). Como instrumentos se utilizaron el International Physical Activity Questionnaire (IPAQ) y el SARC-F. El análisis de los datos fue conducido por medio de las pruebas de Kolmogorov-Smirnov, correlación de Spearman y el análisis de ecuaciones estructurales (p<0,05). Los resultados evidenciaron que los ancianos realizan actividades físicas leves (Md=3) y moderadas (Md=2) semanalmente, pero no actividades vigorosas (Md=0), además de bajo indicativo de sarcopenia (Md=1). El análisis de ecuaciones estructurales reveló que las variables de actividad leves y moderadas presentaron una asociación significativa (p<0,05) y negativa con la puntuación del indicativo de sarcopenia, sin embargo débil (β<0,20), explicando el 7% de su variabilidad. Se concluyó que la práctica de actividades físicas leves y moderadas parece ser un factor interviniente en el indicativo de sarcopenia en ancianos.


ABSTRACT Sarcopenia is a syndrome characterized by progressive loss of muscle mass and associated with adverse health outcomes in older adults. Physical activity has been pointed out as an important tool for its prevention. Therefore, this study investigated the relationship of sedentary lifestyle, duration and frequency of physical activity with the indicator of sarcopenia in older adults. Five hundred and fifty-one physically active older adults enrolled in senior fitness centers of Maringá (PR) participated in this cross-sectional study. The International Physical Activity Questionnaire (IPAQ) and the SARC-F were the instruments used. Data analysis was conducted using the Kolmogorov-Smirnov tests, Spearman correlation coefficient and the Structural Equation Analysis (p<0.05). Results showed that older adults participated in mild to moderate physical activities weekly, but not vigorous ones, besides exhibiting low sarcopenia indicators. Structural Equations analysis revealed that the variables of mild and moderate activity presented a significant (p<0.05) and negative correlations with the sarcopenia indicators score, however weak (β<0.20), explaining its 7% variability. It was concluded that the practice of mild and moderate physical activity affect sarcopenia indicators in older people.

ABSTRACT

Abstract Aim: This study aimed to present the conceptual, procedural, and attitudinal knowledge of the trail guides (TG) in the Serra da Capivara National Park (SCNP) and Caparaó National Park (CNP). Results: Seventy-nine TGs participated in this descriptive-exploratory research, with a qualitative approach, representing 84% (n = 40) of CNP guides and 80% (n = 39) of SCNP guides. Conclusions: The evidence describes the conceptual, attitudinal, and procedural dimensions displayed before and during trail-walking, with differences in conceptual knowledge, discrepancies in procedural knowledge, and equality in attitudinal aspects. The importance of the participation of the area of physical education was highlighted in the training of TGs, alongside the need to include didactic-pedagogical content, environmental education, exercise physiology, movement biomechanics, flora, fauna, notions of minimal or desirable impact, and first aid.

ABSTRACT

Abstract Objective To determine the effect of treadmill walking on maternal heart rate (MHR) and cardiotocographic parameters (basal fetal heart rate [FHR], active fetal movements [AFM], number of accelerations and decelerations, and short-term variation [STV] and long-term variation [LTV] of fetal heart rate) in pregnant women at 36 weeks. Methods A nonrandomized, open clinical trial involving 88 healthy pregnant women submitted to moderate intensity walking and computed cardiotocography in 3 20- minute periods (resting, treadmill walking, and postexercise recovery). Results The mean FHR decreased during walking (resting: 137 bpm; treadmill: 98 bpm; recovery: 140 bpm; p<0.001), with bradycardia occurring in 56% of the fetuses in the first 10minutes of exercise, and in 47% after 20minutes. Bradycardia was not detected in the other phases. The mean STV and HV were 7.9, 17.0, and 8.0 milliseconds (p<0.001) and 7.6, 10.8 and 7.6 bpm (p=0.002) in the resting, walking and recovery phases, respectively. Themean number of fetalmovements in 1 hour was 29.9, 22.2 and 45.5, respectively, in the 3 periods (p<0.001). In overweight/obese women, the mean FHR was lower (p=0.02). Following the logistic regression analysis, two variables remained significantly associated with bradycardia: maternal fitness in the 28th week of pregnancy (protective effect) and maternal weight (increased risk). Conclusion In healthy fetuses, physical exercise proved to be safe, since, although FHR and AFM decreased during treadmill walking, an increase in SVT and LTV was observed.


Resumo Objetivo Determinar o efeito da caminhada em esteira sobre a frequência cardíaca materna (FCM) e parâmetros cardiotocográficos (batimentos cardiofetais basais [BCFs], movimentos ativos fetais [MAFs], número de acelerações e desacelerações e variabilidade de curta [STV] e longa [LTV] duração da frequência cardíaca fetal) em gestantes na 36a semana. Métodos Foi realizado umensaio clínico não randomizado e aberto com 88 gestantes saudáveis submetidas a caminhada de moderada intensidade na esteira e a cardiotocografia computadoriza em 3 momentos de 20 minutos (antes, durante e após a caminhada). Resultados A média dos BCFs diminuiu durante a caminhada, retornando a níveis prévios (antes: 137 bpm; durante: 98 bpm; após: 140 bpm; p<0,001), com bradicardia ocorrendo em 56% dos fetos nos primeiros 10 minutos do exercício, e em 47% após 20 minutos. A bradicardia fetal não foi observada em outrosmomentos (antes ou depois). As médias da STV e da LTV foram 7,9, 17,0 e 8,0milissegundos (p<0,001) e 7,6, 10,7 e 7,6 bpm (p=0,002) antes, durante e após a caminhada, respectivamente. Amédia dos números dos MAFs em 1 hora foi 29,9, 22,2 e 45,5, respectivamente, nos três momentos (p<0,001). Nas mulheres com sobrepeso/obesidade, a média da FCM foi menor (p=0,02). Após a análise de regressão logística, duas variáveis permaneceram significativamente associadas a bradicardia: aptidão maternal na 28a semana de gravidez (efeito protetor) e peso materno (aumento do risco). Conclusão Em fetos saudáveis, o exercício físico mostrou-se seguro, uma vez que, embora os BCFs e osMAFs diminuam durante a caminhada na esteira, foi observado um aumento da SVT e da LTV.

ABSTRACT

Abstract Background: Increases in daily physical activity levels is recommended for patients with peripheral artery disease (PAD). However, despite this recommendation, little is known about the physical activity patterns of PAD patients. Objective: To describe the physical activity patterns of patients with symptomatic peripheral artery (PAD) disease. Methods: This cross-sectional study included 174 PAD patients with intermittent claudication symptoms. Patients were submitted to clinical, hemodynamic and functional evaluations. Physical activity was objectively measured by an accelerometer, and the time spent in sedentary, low-light, high-light and moderate-vigorous physical activities (MVPA) were obtained. Descriptive analysis was performed to summarize patient data and binary logistic regression was used to test the crude and adjusted associations between adherence to physical activity recommendation and sociodemographic and clinical factors. For all the statistical analyses, significance was accepted at p < 0.05. Results: Patients spent in average of 640 ± 121 min/day, 269 ± 94 min/day, 36 ± 27 min/day and 15 ± 16 min/day in sedentary, low-light, high-light and MVPA, respectively. The prevalence of patients who achieved physical activity recommendations was 3.4%. After adjustment for confounders, a significant inverse association was observed between adherence to physical activity recommendation and age (OR = 0.925; p = 0.004), while time of disease, ankle brachial index and total walking distance were not associated with this adherence criteria (p > 0.05). Conclusion: The patterns of physical activity of PAD patients are characterized by a large amount of time spent in sedentary behaviors and a low engagement in MVPA. Younger patients, regardless of the clinical and functional factors, were more likely to meet the current physical activity recommendations.


Resumo Fundamento: Aumentos nos níveis de atividade física diária são recomendados para pacientes com doença arterial periférica (DAP). No entanto, apesar dessa recomendação, pouco se sabe sobre os padrões de atividade física dos pacientes com DAP. Objetivo: Descrever os padrões de atividade física de pacientes com DAP sintomática. Métodos: Este estudo transversal incluiu 174 pacientes com DAP com sintomas de claudicação intermitente. Os pacientes foram submetidos a avaliações clínicas, hemodinâmicas e funcionais. A atividade física foi objetivamente medida por um acelerômetro, e o tempo gasto em atividades sedentárias, de baixa intensidade, de alta intensidade e atividade física moderada-a-vigorosa (AFMV) foi obtido. A análise descritiva foi realizada para resumir os dados dos pacientes e a regressão logística binária foi utilizada para testar as associações brutas e ajustadas entre a adesão à recomendação de atividade física e os fatores sociodemográficos e clínicos. Para todas as análises estatísticas, a significância foi estabelecida em p < 0,05. Resultados: Os pacientes gastaram em média 640 ± 121 min/dia, 269 ± 94 min / dia, 36 ± 27 min/dia e 15 ± 16 min/dia em atividades sedentárias, de baixa intensidade, alta intensidade e AFMV, respectivamente. A prevalência de pacientes que atingiram as recomendações de atividade física foi de 3,4%. Após ajuste para fatores de confusão, observou-se associação inversa significativa entre adesão à recomendação de atividade física e idade (OR = 0,925; p = 0,004), enquanto tempo de doença, ITB e distância total de caminhada não se associaram a esse critério de adesão (p> 0,05). Conclusão: Os padrões de atividade física dos pacientes com DAP são caracterizados por uma grande quantidade de tempo gasto em comportamentos sedentários e um baixo envolvimento na AFMV. Pacientes mais jovens, independentemente dos fatores clínicos e funcionais, apresentaram maior probabilidade de atender às recomendações atuais de atividade física.

ABSTRACT

RESUMO O objetivo do estudo foi verificar se existem diferenças na força muscular dos membros inferiores (MMII) e na habilidade de locomoção de indivíduos pós-acidente vascular encefálico (AVE) crônico, classificados como deambuladores comunitários ou não comunitários. Foi realizado um estudo transversal em 60 indivíduos pós-AVE crônico, divididos em deambuladores comunitários (n=33) e não comunitários (n=27) pela velocidade de marcha. A força muscular de sete grupos musculares bilaterais de MMII foi avaliada por meio do teste do esfigmomanômetro modificado e habilidade de locomoção pelo ABILOCO. Estatísticas descritivas foram utilizadas para caracterizar a amostra, e o teste t de Student para amostras independentes, a fim de comparar os dois grupos de indivíduos pós-AVE. Observou-se que os deambuladores comunitários apresentaram maiores valores de força muscular para a maioria dos grupos musculares de MMII (−0,973≥t≥−3,189; p≤0,04), e na habilidade de locomoção (t=−2,841; p=0,006). Os indivíduos pós-AVE crônico deambuladores comunitários possuem maior força muscular de MMII e mais habilidade de locomoção em comparação aos deambuladores não comunitários. Sugere-se que a avaliação fisioterapêutica de indivíduos pós-AVE inclua, além da mensuração da força muscular de MMII e seu tratamento, a mensuração da percepção da habilidade de locomoção, para análises da evolução do paciente e da eficácia da conduta terapêutica.


RESUMEN El objetivo del estudio fue verificar si existen diferencias en la fuerza muscular de los miembros inferiores (MMII) y en la habilidad de locomoción de individuos post-accidente cerebrovascular encefálico (ACV) crónico, clasificados como deambuladores comunitarios o no comunitarios. Se realizó un estudio transversal en 60 individuos post-ACV crónico, divididos en deambuladores comunitarios (n = 33) y no comunitarios (n = 27) por la velocidad de marcha. La fuerza muscular de siete grupos musculares bilaterales de MMII fue evaluada por medio de la prueba del esfigmomanómetro modificado, y la habilidad de locomoción por el ABILOCO. Las estadísticas descriptivas se utilizaron para caracterizar la muestra, y la prueba t de Student para muestras independientes con el fin de comparar los dos grupos de sujetos post-ACV. Se observó que los deambuladores comunitarios presentaron mayores valores de fuerza muscular para la mayoría de los grupos musculares de MMII (−0,973≥t≥−3,189; p≤0,04), y en la habilidad de locomoción (t=−2,841; p=0,006). Los individuos post-ACV crónico deambuladores comunitarios poseen mayor fuerza muscular de MMII y más habilidad de locomoción en comparación a los deambuladores no comunitarios. Se sugiere que la evaluación fisioterapéutica de individuos post-ACV incluya, además de la medición de la fuerza muscular de MMII y su tratamiento, la medición de la percepción de la habilidad de locomoción, para análisis de la evolución del paciente y de la eficacia de la conducta terapéutica.


ABSTRACT The objective of this study was to verify if there are differences in the lower-limb muscle strength (LL) and in the locomotion ability among post-stroke patients classified as community or non-community ambulators. A cross-sectional study was conducted in 60 post-chronic stroke subjects, divided into community (n=33) and non-community (n=27) ambulators by gait speed. The muscle strength of seven bilateral muscle groups of LL was evaluated through the modified sphygmomanometer test and locomotion ability through ABILOCO. Descriptive statistics were used to characterize the sample, and Student's t-test was used for independent samples to compare the two groups of post-stroke individuals. We observed that community ambulators had higher values of muscle strength for most muscle groups of LL (−0.973≥t≥3.189; p≤0.04), and in the locomotion ability (t=−2.841; p=0.006). Community ambulators showed higher LL muscle strength and better locomotion ability compared with non-community ambulators. Physiotherapeutic evaluation of post-stroke individuals should include, besides the measurement of LL muscle strength and its treatment, the measurement of the perception of locomotion ability to analyze the evolution of the patient and the efficacy of the therapeutic behavior.

ABSTRACT

Determining kinematics of hindlimbs of theropod dinosaurs has been a challenge. Since cursorial birds are phylogenetically closest to theropod dinosaurs they are commonly used as a kinematic model of theropod dinosaur locomotion. Using a comparative biomechanical approach, we found that cursorial birds have a different morphology of legs than non avian theropodos and that appears to be that felines and ungulates share more morphological properties in the hindlimbs with theropod dinosaurs than cursorial birds. We calculated the ratio between the lower leg and the femur, and the relative length of the tibia and the metatarsus with respect to the length of the femur in cursorial birds, as well as felines, ungulates and non-avian theropods. We found that as the length of the femur increases, the length of the lower leg increases similarly in felines, ungulates and non-avian theropods. On the other hand, existing and extinct cursorial birds did not follow this pattern. This observation suggests that the hindlimb of cursorial birds are not well suited to serve as kinematic models for hindlimb of extinct theropod dinosaur locomotion.


Determinar la cinemática de los miembros pelvianos de los dinosaurios terópodos ha sido un desafío. Dado que las aves corredoras son filogenéticamente más cercanas a los dinosaurios terópodos, son comúnmente utilizadas como modelo cinemático de la locomoción del dinosaurio terópodo. Usando un enfoque biomecánico comparativo, encontramos que las aves corredoras tienen una morfología de pies diferente a la de los terópodos no aviares y parece ser que los felinos y los ungulados comparten más propiedades morfológicas en los pies con los dinosaurios terópodos que las aves corredoras. Calculamos la proporción entre la parte inferior de la pierna y el fémur, y la longitud relativa de la tibia y el metatarso con respecto a la longitud del fémur en aves corredoras, así como en los terópodos no aviares y ungulados. Encontramos que a medida que aumenta la longitud del fémur, la longitud de la parte inferior de la pierna aumenta de manera similar en los terópodos, los ungulados y los terópodos no aviares. Por otro lado, las aves corredoras existentes y extintas no siguieron este patrón. Esta observación sugiere que el miembro pelviano de las aves corredoras no es adecuada para servir como modelos cinemáticos de locomoción del miembro pelviano del dinosaurio terópodo extinto.

ABSTRACT

Resumen Introducción: La prueba de caminata de carga progresiva (PCCP) es una prueba incremental que permite la evaluación funcional de las enfermedades respiratorias. Esta prueba muestra una mayor correlación entre la distancia recorrida y el consumo máximo de O2 comparada con la prueba de marcha de seis minutos. En la actualidad, no contamos con valores de referencia en la población pediátrica nacional. Objetivo: Conocer la distancia recorrida en niños en la prueba. Material y Método: Estudio descriptivo correlacional. La muestra final fue de 60 sujetos (35 niños y 25 niñas) elegidos al azar en un rango de edad de 10 a 14 años. Durante la prueba se registró la distancia recorrida (DR) en metros, frecuencia cardíaca basal y final (FC), disnea, sensación subjetiva de fatiga (SSF), género, peso (kg), talla (m) y respuesta cardíaca al ejercicio (RCE). Se realizó estadística descriptiva en ambos grupos seguida de una prueba "t" para analizar las diferencias entre género. Se aplicó el coeficiente de correlación de Pearson para verificar la correlación entre las variables. Los resultados fueron expresados en medias ± desviación estándar (DE). Resultados: El promedio de la DR del conjunto de los 60 menores fue 596,2 ± 178,7 m; para la DR en las niñas el promedio fue de 531,6 ± 136,4 m y la DR promedio en los niños de 642,3 ± 192,4 m (p = 0,017). El promedio de la talla para los niños fue de 1,50 ± 0,08 m y para las niñas de 1,53 ± 0,08 m. El coeficiente de correlación de Pearson fue de 0,570 (p < 0,001) entre el promedio de DR para ambos géneros y la RCE. Conclusiones: Los niños alcanzan una mayor DR que las niñas en la PCCP. No se encontró influencia de la edad, peso, estatura o IMC en la distancia recorrida para la PCCP. En el conjunto de los 60 niños se observó una correlación positiva entre la DR y la RCE.


Background: The "incremental shuttle walking test" (ISWT) is an incremental test that allows the functional evaluation of respiratory diseases. It shows a greater correlation between distance walked and the maximum O2 uptake compared to the six-minute walking test. Presently we do not have reference values in Chilean pediatric population. Objective: To know the distance walked by children in the test. Material and Method: This was a correlational descriptive study. The final sample consisted of 60 subjects (35 boys and 25 girls) randomly selected from an age range from 10 to 14 years-old. During the test, walked distance (WD) in meters, basal and final heart rate (HR), dyspnea, subjective sensation of fatigue (SSF), gender, weight (kg), height (m) and cardiac response to exercise (CRE) were recorded. Descriptive statistics were performed in both series followed by a t-test to look for differences among genders. Pearson's correlation coefficient was used to verify the correlation between variables. Results were expressed as mean ± SD. Results: Mean of WD in all the 60 children together was 596.2 ± 178.7 m; in average WD in girls series was 531.6 ± 136.5 m and in boys series was 642.3 ± 192.4 m (p = 0.017). The average height for boys was 1.50 ± 0.08 m and for girls was 1.53 ± 0.08 m (p = 0.245). The average BMI for boys was 18.3 ± 1.6 kg/m2 and for girls was 19.3 ± 2.2 kg/m2 (p = 0.041). Pearson's correlation coefficient between the average of meters walked for all the 60 children together and CRE was 0.570 (p < 0.001). Conclusions: Boys showed a greater WD than girls in ISWT. There was no influence of age, weight, height or BMI on distance walked on the ISWT A positive correlation is shown between the WD and the CRE.

ABSTRACT

Resumo A prática regular da caminhada contribui para melhor qualidade de vida, reduzindo riscos para doenças cardiovasculares. O objetivo deste artigo é verificar a associação entre fatores sociodemográficos e de saúde relacionados à prática de caminhada de adultos no contexto rural brasileiro. Estudo transversal com 567 adultos. A variável desfecho foi a prática regular de caminhada (≥ 150 minutos/semana) e as de exposição foram as sociodemográficas, antropométricas, clinico laboratoriais e autopercepção de saúde. As análises foram realizadas pelo teste do qui-quadrado e regressão de Poisson, considerando p ≤ 0,05. Apenas 34,7% da população pratica a caminhada de forma regular. O sexo feminino (RP 0,84; IC95% 0,78-0,89), a idade entre 31-45 anos (RP 1,11; IC95% 1,02-1,22 para comparação entre pessoas de 18-30 anos) e a autopercepção de saúde ruim/regular (RP 0,90; IC95% 0,84-0,97 para a comparação entre pessoas com autopercepção excelente/boa) permaneceram independentemente associadas à prática regular de caminhada. A idade entre 31-45 anos e o sexo masculino foram positivamente associados à caminhada e a percepção de saúde regular/ruim apresentou associação negativa. Esses achados podem sugerir que as políticas públicas de incentivo a atividade física nas áreas urbanas podem ser aplicadas também nas rurais.


Abstract The regular practice of walking can contribute to a better quality of life, reducing the risk of cardiovascular disease. Objective: To assess the association between sociodemographic and health factors related to adult practice of walking in the Brazilian rural context. Methods: Cross-sectional study of 567 adults. The outcome variable was the regular practice of walking (≥150 minutes per week) and the explanatory variables were sociodemographic factors, anthropometric measures, laboratory tests and self-perceived health. The chi-square test and Poisson regression were used in analysis, considering p ≤ 0.05. Results: Only 34.7% of the population practices walking regularly. Women (PR 0.84, 95% CI 0.78-0.89), age of 31-45 years (OR 1.11, 95% CI 1.02-1.22, comparing to 18-30 years), and self-perception of poor/fair health (OR 0.90, 95% CI 0.84-0.97 comparing to people with great/good health) remained independently associated with regular practice of walking. Conclusion Age between 31 and 45 years and males were positively associated with walking and the perception of poor/fair health had negative association. These findings may suggest that public policies to encourage physical activity in urban areas should also be applied to rural areas.

ABSTRACT

To compare high active (HA) and low active (LA) adolescent's physical activity (PA) levels in three different domains: commuting to school, physical education (PE) class and recess time at school. Method: This is a cross-sectional study, with a quantitative approach and random sample of 176 (105 girls) adolescents aged 14 - 18 years old from 10 urban public high schools in southern from Brazil. PA levels were measured using a pedometer. The average number of steps was recorded on the way to school, during PE classes and during school recess time. Participants were classified as HA and LA according to Tudor-Locke's cut-off points. Data were analyzed using descriptive statistics and One-Way ANOVA stratified by sex. Results: Data showed differences of mean values between school commuting PA for girls (LA: 1057.60; HA: 1624.54; Δ: 566.94; p<0.001), during PE class (LA: 1401.75, HA: 1701.10; Δ: 308.53; p<0.05) and in recess time (LA: 443.09, HA: 611.98; Δ: 168.89; p=0.001), whereas for boys, differences only found between the mean values of PA during PE class (LA: 1787.91, HA: 2511.20; Δ: 723.29; p<0.01). Conclusion: HA girls are consistently more active in each domain analyzed compared to LA counterparts, while for boys PE class was the domain that differentiated the HA vs. LA adolescents. This study highlights some potential settings to be included in the policies focused in enhance PA levels among adolescents namely in the context of school PE.(AU)

ABSTRACT

The current study examined the relationship between cognitive performances (executive function, selective attention and reaction time), fine motor coordination skills and perceived difficulty after active transport to school. Method: Fifteen right-handed children's underwent session, 15-min walking session at 30% (WS1) and 15-min walking session (WS2) at 50% of maximal aerobic speed. Subjects performed tests to evaluate executive function, reaction time and selective attention. After each trial, a questionnaire of perceived difficulty (PD) was completed. Results: Average time in TMT part A (F(2,22) = 4.44; p = 0.024; η2= 0.288) and TMT part B (F(2,22) = 4.54; p = 0.022; η2= 0.292), and committed errors (F(2,22) = 7.78; p = 0.003; η2= 0.414) was improved after walking sessions in comparison by CS. The mean scores were significantly higher after walking sessions for both long and short-distance throws (p < 0.05). Moreover, a significant negative correlation was found between committed errors (TMT part B) and both dart throwing consistency and accuracy (r = - 0.6; r = - 0.64; p < 0.05) (respectively). Post-hoc analysis showed that PD was better after walking sessions with low intensity for both short and long throwing distance. However, it seems that walking session with sustained intensity allows speed and accuracy improvement of cognitive processing. Conclusion: Thus, active walking to school with low intensity was sufficient to produce positives changes in psychomotor performance and decrease in perceived difficulty scores. By including individual differences in gross motor coordination as well as physical activity level, the exact nature of the link between psychomotor skills and cognitive performance could be more addressed.(AU)

ABSTRACT

The purpose of this study was to look at the determinants of the unsteady walking (UW) symptom in patients with type 2 diabetes mellitus (T2DM) by defining if UW and/or the Diabetic Neuropathy Symptoms Score (DNSS) are associated with positive scores in Beck's Depression Inventory (BDI) and with a positive Michigan Neuropathy Screening Instrument score (MNSI). We evaluated 203 T2DM patients without visible gait disturbances. They were divided into UW (+) and UW (−) or DNSS (+) and DNSS (−) according to symptoms. We found a prevalence of 48.3% for UW (+) and of 63% for DNSS (+) in our sample. In univariate analysis, the presence of UW was significantly associated with waist circumference (P=0.024), number of comorbidities (P=0.012), not practicing physical exercise (P=0.011), positive BDI score (P=0.003), presence of neuropathic symptoms by the MNSI questionnaire (P<0.001), and positive diabetic neuropathy screening by MNSI (P=0.021). In multivariate analysis, UW (used as a dependent variable) was independently associated with a positive BDI score (P<0.001; 95%CI=1.01-1.03), T2DM duration (P=0.023; 95%CI=1.00-1.03), number of co-morbidities (P=0.032; 95%CI=1.01-1.37), and a sedentary lifestyle (P=0.025; 95%CI=1.06-2.5). The UW symptom and a positive DNSS are more closely related to a positive score for depression than to presence of neuropathy in T2DM.

ABSTRACT

OBJECTIVE: To verify the effect of an endurance exercise program in middle stages of Parkinson's disease. METHODS: The patients were two women and seven men with Parkinson's disease, aged 56 to 74 years, classified at Hoehn and Yahr stages 2 to 2.5. The study was designed as an open long-term pilot trial over three months of supervised treadmill exercise training. Cardiopulmonary exercise test evaluations were performed before the start of the study (test 1) and after three months (test 2). The main outcome measure was walking economy (i.e., the rate of oxygen consumption during gait) measured between VT1 and VT2 speeds and Oxygen consumption (VO2). RESULTS: No changes (p=0.551) were observed for maximal oxygen uptake (VO2max, 24.6 vs 23.6 mL.kg-1.min-1) between tests. The walking economy was 20% better (p<0.001) after three months of aerobic endurance training (266.7 vs 212.6 mL.kg-1.km-1, pre- vs. post-training); the Cohen's "d" effect size (ES) was 0.99, a very large effect. CONCLUSION: Evidence from this pilot study in individuals with Parkinson's disease suggests that gains in walking economy occurs with a treadmill-training program without gain in aerobic power, but which may positively reduce the energy expenditure of activities of daily living in these patients.


OBJETIVO: Verificar o efeito de um programa de treinamento físico aeróbio em estágios intermediários da doença de Parkinson (PD). MÉTODOS: Os pacientes eram duas mulheres e sete homens com PD, com idade entre 56 e 74 anos, classificados como estágios Hoehn e Yahr 2 a 2,5. O estudo foi concebido como um ensaio piloto aberto de longo prazo durante três meses de treinamento supervisionado e realizado em esteira ergométrica. As avaliações da troca gasosa pelo teste de exercício cardiopulmonar foram realizadas antes do início do estudo (teste 1) e após três meses (teste 2). A determinação da economia de caminhada (taxa de consumo de oxigênio durante a marcha) foi medida entre as velocidades do primeiro e do segundo limiar (LV1 e LV2) e do consumo de oxigênio (VO2) entre as duas velocidades por interpolação. RESULTADOS: Não foram observadas alterações (P = 0,153) para o consumo máximo de oxigênio (VO2max: 26,7 vs. 24,2 mL.kg-1.min-1) após o período de intervenção. A economia de caminhada foi 23% maior (P <0,001) após três meses de treinamento físico aeróbio (273,4 vs. 209,4 mL.kg-1.km-1, ES = 0.99, muito alto). CONCLUSÃO: Evidências deste estudo piloto em indivíduos com DP sugerem que os ganhos na economia de caminhada podem ocorrer com um programa de treinamento de "endurance" aeróbica na esteira sem ganho na potência aeróbia, mas que positivamente pode reduzir o gasto de energia das atividades da vida diária nesses pacientes.

ABSTRACT

ABSTRACT Objective: To analyze the association between active commuting and blood pressure in adolescents. Methods: This is a cross-sectional study with high school students from public education network in the state of Pernambuco, Brazil. Data from 6039 students (14 to 19 years) were collected using a questionnaire. "Physically inactive" were considered those who reported not to walk or ride a bicycle to and from school on any day of the past week, and/or those who, regardless of the weekly frequency of practice this type of activity, reported the duration of commuting to school was less than 20 minutes (round trip). The high blood pressure was obtained by Omron HEM 742 equipment. Adolescents with high blood pressure were defined as those with higher blood pressure or equal to the 95th percentile for age, sex and height. Regression logistic analyses were used to assess the association between active commuting and high blood pressure, considering adjustments for the following confounders: sex, age, overweight, total physical activity, socioeconomic level, place of residence. Results: The prevalence of high blood pressure was 7.3%, and 79.3% were considered insufficiently active in commuting. There was an association between high blood pressure and active commuting only among those living in rural areas (OR = 6.498; 95% CI = 1.513-27.900), and the same was not observed among those living in urban areas (OR = 1.113; 95% CI = 0.812-1.526). Conclusion: Active commuting can be considered a protective factor for high blood pressure in adolescents living in rural areas.


RESUMO Objetivo: Analisar a associação entre o deslocamento ativo e a pressão arterial elevada em adolescentes. Métodos: Trata-se de um estudo transversal com estudantes do Ensino Médio da rede pública estadual de Pernambuco. Os dados de 6.039 estudantes de 14 a 19 anos foram coletados mediante questionário. Foram considerados "insuficientemente ativos" aqueles que relataram que em nenhum dos dias da última semana realizaram deslocamentos a pé ou de bicicleta e/ou aqueles que, independentemente da frequência semanal de prática desta atividade, relataram que a duração do deslocamento para a escola era inferior a 20 minutos (ida e volta). A pressão arterial elevada foi obtida por meio do equipamento Omron HEM 742. Foram definidos como adolescentes com pressão arterial elevada aqueles com pressão arterial maior ou igual ao percentil 95 para idade, sexo e estatura. Recorreu-se à análise de regressão logística para verificar a associação entre deslocamento ativo e pressão arterial elevada, considerando ajustes para os fatores de confusão sexo, idade, sobrepeso, atividade física total, nível socioeconómico e zona de moradia. Resultados: A prevalência de pressão arterial elevada foi de 7,3% e de inatividade física no deslocamento foi de 79,3%. Foi verificada associação entre pressão arterial elevada e deslocamento ativo apenas entre aqueles que moram em zona rural (OR=6,498; IC95%=1,513-27,900). O mesmo não foi verificado entre aqueles que moravam na zona urbana (OR = 1,113; IC95%=0,812-1,526). Conclusão: O deslocamento ativo póde ser considerado fator de proteção para a pressão arterial elevada nos adolescentes que moravam na zona rural.

ABSTRACT

ABSTRACT Objective: To investigate if middle-aged and older adults with a higher education would differ from those with an average education in cognitive-motor tasks involving lower limb function. Methods: A walking version of the Trail Making Test (Walking Executive Function Task, [WEFT]) was used. Eighty volunteers (40: 50-65 years; 40: 66-80 years) were subdivided into average (6-11years of education) and higher education (12-17 years). They received two training sessions (session 1: eight repetitions, session 2: four repetitions), with a one week-interval between them. The Timed Up and Go (TUG) test was performed before and after the training. Results: Volunteers with an average education showed longer times on the WEFT than those with a higher education. Older adults showed lower retention than middle-aged adults (p < 0.001). The TUG was faster after the WEFT training (p < 0.001). Conclusion: The impact of education was observed when locomotion was associated with cognitive tasks. Average education resulted in poorer performance and learning than higher education, mainly in older adults. Gait speed increased after training.


RESUMO Objetivo: Investigar se adultos e idosos com escolaridade alta teriam aprendizagem diferente de adultos e idosos com escolaridade média em uma tarefa cognitivo-motora envolvendo função de membros inferiores. Método: A tarefa foi baseada no Trail Making Test (Tarefa de Deambulação Funcional, TDF). Oitenta voluntários (40:50-65 anos; 40:66-80 anos) foram subdivididos em escolaridade média (6-11 anos) e alta (12-17 anos) e realizaram duas sessões de treinamento (1: oito repetições, 2: quatro repetições), com intervalo de uma semana. O Timed Up and Go (TUG) foi realizado antes e após o treinamento. Resultados: Voluntários com escolaridade média levaram mais tempo para concluir a TDF do que voluntários com escolaridade alta (p < 0.001). Idosos apresentaram menor retenção do que adultos (p < 0.001). TUG foi mais rápido após o treinamento. Conclusão: O impacto da escolaridade foi observado quando a locomoção foi associada com tarefas cognitivas. Voluntários com escolaridade média apresentaram menor aprendizagem do que com escolaridade alta, principalmente idosos. A velocidade da marcha aumentou com o treinamento.

ABSTRACT

Abstract The purpose of this study was to determine the relationship between peak cadence indicators and body mass index (BMI) and body fat percentage (BF%)-defined weight status in children. The sample comprised 485 Brazilian children. Minute-by-minute step data from accelerometry were rank ordered for each day to identify the peak 1-minute, 30-minute and 60-minute cadence values. Data were described by BMI-defined and bioelectrical impedance-determined BF% weight status. BMI-defined normal weight children had higher peak 1-minute (115.5 versus 110.6 and 106.6 steps/min), 30-minute (81.0 versus 77.5 and 74.0 steps/min) and 60-minute cadence (67.1 versus 63.4 and 60.7 steps/min) than overweight and obese children (p<.0001), respectively. Defined using %BF, normal weight children had higher peak 1-minute (114.5 versus 106.1 steps/min), 30-minute (80.4 versus 73.1 steps/min) and 60-minute cadence (66.5 versus 59.9 steps/min) than obese children (p<.0001). Similar relationships were observed in boys; however, only peak 1- minute cadence differed significantly across BMI and %BF-defined weight status categories in girls. Peak cadence indicators were negatively associated with BMI and BF% in these schoolchildren and significantly higher among normal weight compared to overweight or obese children.


Resumo O objetivo do estudo foi determinar a relação entre indicadores de pico de cadência com índice de massa corporal (IMC) e percentual de gordura corporal (% GC) definidos pelo estado de peso corporal de crianças. Participaram 485 crianças brasileiras. Minutos de acelerometria foram ranqueados para identificar os valores de picos de cadência de 1, 30 e 60 minutos. O estado de peso corporal foi apresentado pelo IMC e %GC, avaliados pela bioimpedância elétrica. No IMC, crianças eutróficas apresentaram maior pico de cadência de 1 minuto (115,5 versus 110,6 e 106,6 passos/min), 30 minutos (81,0 versus 77,5 e 74,0 passos/min) e 60 minutos (67,1 versus 63,4 e 60,7 passos/min) do que aqueles com excesso de peso e obesidade (p < 0,001). Na %GC, crianças eutróficas apresentaram maior pico de cadência de 1 minuto (114,5 versus 106,1 passos/min), 30 minutos (80,4 versus 73,1 passos/min) e 60 minutos (66,5 versus 59,9 passos/min) do que as obesas. Relações semelhantes foram observadas nos meninos; no entanto, apenas o pico de cadência de 1 minuto foi significativamente diferente nas categorias do estado de peso corporal definido pelo IMC e %GC nas meninas. Indicadores de pico de cadência foram negativamente associados com IMC e %GC e maior nos eutróficos do que naqueles com excesso de peso e obesidade.

ABSTRACT

ABSTRACT Objective: The purpose was to evaluate the effectiveness of a progressive muscle strengthening program using a Swiss ball for AS patients. Methods: Sixty patients with AS were randomized into the intervention group (IG) or the control group (CG). Eight exercises were performed by the IG patients with free weights on a Swiss ball two times per week for 16 weeks. The evaluations were performed by a blinded evaluator at baseline and after 4, 8, 12 and 16 weeks using the following instruments: the one-repetition maximum test (1 RM), BASMI, BASFI, HAQ-S, SF-36, 6-minute walk test, time up and go test, BASDAI, ASDAS, ESR and CRP dosage and Likert scale. Results: There was a statistical difference between groups for: strength (1 RM capacity) in the following exercises: abdominal, rowing, squat, triceps and reverse fly (p < 0.005); 6-minute walk test (p < 0.001); timed up and go test (p = 0.025) and Likert scale (p < 0.001), all of them with better results for the IG. No differences were observed between the groups with respect to the functional capacity evaluation using the BASFI, HAQ-S, BASMI, SF-36, TUG, ASDAS, ESR and CPR dosage. Conclusions: Progressive muscle strengthening using a Swiss ball is effective for improving muscle strength and walking performance in patients with AS.


RESUMO Objetivo: Avaliar a efetividade de um programa de fortalecimento muscular progressivo com o uso de uma bola suíça em pacientes com espondilite anquilosante (EA). Métodos: Sessenta pacientes com EA foram randomizados em grupo intervenção (GI) ou grupo controle (GC). Os pacientes com EA fizeram oito exercícios com pesos livres em uma bola suíça duas vezes por semana durante 16 semanas. As avaliações foram feitas por um avaliador cego no início do estudo e após quatro, oito, 12 e 16 semanas com os seguintes instrumentos: teste de uma repetição máxima (1 RM), Basmi, Basfi, HAQ-S, SF-36, teste de caminhada de seis minutos, Timed up and go test, Basdai, Asdas, dosagem de VHS e PCR e escala de Likert. Resultados: Houve uma diferença estatisticamente significativa entre os grupos em relação à força (capacidade no teste de 1 RM) nos seguintes exercícios: abdominal, remada, agachamento, tríceps e crucifixo invertido (p < 0,005); teste de caminhada de seis minutos (p < 0,001); Timed up and go test (p = 0,025); e escala de Likert (p < 0,001), todos com melhores resultados no GI. Não foram observadas diferenças entre os grupos em relação à avaliação da capacidade funcional com Basfi, HAQ-S, Basmi, SF-36, TUG, Asdas, VHS e dosagem de PCR. Conclusões: O fortalecimento muscular progressivo com uma bola suíça é efetivo em melhorar a força muscular e o desempenho na caminhada em pacientes com EA.

ABSTRACT

ABSTRACT OBJECTIVE To quantify the intensity adopted by walkers in public squares and check the occurrence and magnitude of post-exercise hypotension in the spontaneously adopted intensity and in a prescribed intensity. METHODS In 98 volunteers (38 of them being hypertensive), walkers in public squares of the city of João Pessoa, State of Paraíba, Brazil, we have identified the intensity of a usual training monitored by heart rate and we have investigated the occurrence and magnitude of post-exercise hypotension. Subsequently, participants were instructed to walk with moderate intensity. Blood pressure was measured after rest and during post-exercise recovery. RESULTS Of the total participants, 41% of the hypertensive and 36% of the normotensive individuals walked with light intensity. With the prescription, intensity increased to 55% and 52%, for the hypertensive and normotensive individuals, respectively. In the usual and prescribed intensity, the hypertensive individuals had post-exercise hypotension of -3.7±11.6 mmHg and -4.72±12.8 mmHg, respectively. There was no correlation between post-exercise hypotension and the initial systolic component of the hypertensive individuals (r2 = 0.2; p < 0.002). CONCLUSIONS Walkers in public squares choose light intensity for walking. When they exercise with the prescribed intensity, they increase the intensity, but the magnitude of the PEH is not increase with this guidance.


RESUMO OBJETIVO Quantificar a intensidade adotada por caminhantes em praças públicas e verificar a ocorrência e a magnitude da hipotensão pós-exercício na intensidade espontaneamente adotada e em uma intensidade prescrita. MÉTODOS Em 98 voluntários (38 hipertensos), caminhantes em praças públicas da cidade de João Pessoa, PB, identificamos a intensidade de um treino habitual monitorada por meio da frequência cardíaca e averiguamos a ocorrência e magnitude de hipotensão pós-exercício. Posteriormente, os participantes foram instruídos a caminhar com intensidade moderada. A pressão arterial foi aferida após o repouso e durante a recuperação pós-exercício. RESULTADOS Do total de participantes, 41% dos hipertensos e 36% dos normotensos caminhavam com intensidade leve. Com a prescrição, a intensidade aumentou para 55% e 52%, para hipertensos e normotensos. Na intensidade habitual e prescrita, os hipertensos obtiveram hipotensão pós-exercício de -3,7±11,6 mmHg e -4,72±12,8 mmHg. Houve correlação entre hipotensão pós-exercício e o componente sistólico inicial dos hipertensos (r2 = 0,2; p < 0,002). CONCLUSÕES Caminhantes em praças públicas selecionam intensidade leve para realização de caminhada. Quando realizam exercício com intensidade prescrita, aumentam discretamente a intensidade, mas não obtêm aumento da magnitude da HPE com esta orientação.

ABSTRACT

AIMS: The aim of the study was to determine the effects of deep-water running on muscle function and functionality in community dwelling old women. METHODS: Older women (n=19) were randomly assigned to one of the two groups: deep-water running (DWR: n=09, 64.33±4.24 years, 75.15±12.53 kg, 160.45±7.52 cm; or control group CG: n=10, 64.40±4.22 years, 74.46±12.39 kg, 158.88±5.48 cm). The DWR group carried out 18 weeks of deep-water running, twice/week 50 min sessions. Dynamic isokinetic strength for the lower limb and functionality was assessed before and after intervention. RESULTS: DWR group increased peak torque, total work and average power of the knee and hip flexors and extensors. Additionally showed better performance on gait speed, timed up and go test, five-times-sit-to-stand-test repetitions from a chair as well as the six-minute walk test. CONCLUSION: The deep-water running program was effective to improve muscle function and functionality.(AU)
