    Locomotion is the process by which a being moves from one place to another, including stopping, changing speed, changes in direction and adaptation to changes in terrain. Human walking follows a pattern, and it is one of the forms of locomotion that most calls the attention of researchers. Its variation among a group may indicate pathological conditions that influence the treatment and rehabilitation of patients with low mobility. The objective of this article is to carry out a review for the development of a low-cost instrumented treadmill that can assist in the rehabilitation, treatment and follow-up of patients with stroke, and for that, a search of articles related to the topic was carried out in databases such as ScienceDirect, PubMed and others. The results obtained were satisfactory and enabled the creation of a good database. It was possible to conclude that there is a diversity of existing resources and that it is up to the professionals to direct their choice to the one that suits them best

    Atualmente há uma grande procura de hipertensos para a prática de atividades físicas. Embora venha sendo bastante investigada e documentada, a influência da intensidade do exercício na magnitude e duração ainda é controversa. O objetivo desse estudo foi analisar o efeito agudo de exercícios resistidos e aeróbicos sobre a pressão arterial em homens hipertensos leves. A amostra foi dividida em dois grupos, grupo (ER) Exercício Resistido (n=7) e grupo (EA) Exercício Aeróbico (n=7). A PAS e PAD foram aferidas antes de cada sequência de exercícios por métodos auscultatórios e imediatamente após o termino de cada sequência, sendo monitorado em ciclos de 15 minutos, em repouso absoluto durante 60 minutos para comparar a magnitude e duração do comportamento da pressão arterial pós-treino. Foram utilizados os seguintes protocolos de treinamento com duração total de três dias sendo dias alternados. Grupo EA 40 minutos na esteira, com 80% da frequência cardíaca máxima e o grupo ER 4 sets de 20 repetições com 50% de 1RM, com intervalos de 2 a 3 minutos entre exercícios e 60 a 90 segundos por séries. E foi encontrado um maior efeito hipotensor no grupo ER comparado ao grupo EA pós-treino. Portanto, o estudo indica que o exercício de força não parece oferecer risco quando ao aumento da PA e da FC em indivíduos hipertensos em resposta aguda ao treino, indicando ser seguro para essa população

    Background: Preventive and positive online coping strategies are essential for harm reduction associated with alcohol abuse among older adults in pandemic and social isolation scenarios. The objectives were to examine the relationship between alcohol use/abuse and physical capacity/self-care to perform the physical activities of daily living or impairment of the functional capacity of the elderly in the COVID-19 pandemic. Methods: An online cross-sectional survey was carried out. One hundred and one elderly people in the city of São Paulo, Brazil, participated in a community program. Results: Most participants (52.5%) showed excellent self-care skills. Approximately 12% of participants reported problems related to alcohol use/abuse. There was no association between self-care ability and abuse and probable alcohol dependence. Conclusions: Although most participants have excellent self-care and functional capacity and have not evidenced alcohol use/abuse, health professionals need to systematically provide information to prevent alcohol abuse, especially in scenarios of great emotional distress, such as in a pandemic. In addition, the online meetings held by the UAPI program were shown to be opportunities for social interaction and were essential to minimize the negative effects of the possible presence of alcohol use/abuse and the deteriorating performance of physical activities of daily living during a pandemic outbreak for the elderly

    Resumen del trabajo presentado al VI Congreso del Neolítico en la Península Ibérica: "Los cambios económicos y sus implicaciones sociales durante el Neolítico de la Península Ibérica", celebrado en Granada del 22 al 26 de junio de 2016.-- et al.El marco del proyecto I+D: “Aproximación a las primeras comunidades neolíticas del NE peninsular a través de sus prácticas funerarias” (2011-2015), y su continuidad para los próximos cuatro años al haber sido renovado, tiene por objetivo conocer cada día más y mejor las comunidades de agricultores y pastores que entre finales del V e inicios del IV milenio cal BC ocuparon y enterraron a sus muertos en el noreste de la Península Ibérica. El contexto de estudio es excepcional, puesto que aquellas comunidades inhumaron sistemáticamente a sus congéneres en tumbas habitualmente individuales y ocasionalmente junto a otro individuo. En esta presentación no sólo queremos mostrar los nuevos análisis y metodologías que estamos aplicando al estudio de los restos humanos, sino también el modelo de trabajo que hemos seguido. A este respecto, tres aspectos son fundamentales: 1) las dataciones absolutas son el eje que vertebra los posteriores análisis; 2) la colaboración con los distintos investigadores/as y laboratorios debe ser estrecha (no es cuestión de solicitar los resultados de un análisis a un laboratorio sino trabajar con las personas que manipulan las muestras y conocen los pros y contras de cada una de las técnicas empleadas) y 3) los estudios y análisis a realizar confluyen para responder a las hipótesis planteadas. A este respecto, en el proyecto hemos tenido la fortuna de poder colaborar con numerosos investigadores/as cuya especialidad versa alrededor de los restos funerarios y que firman la presente comunicación: análisis isotópicos, Adn, tafonomía funeraria, estudios de stress muscular y análisis de morfología dental.Peer Reviewe

    First narrow-band search for continuous gravitational waves from known pulsars in advanced detector data

    Spinning neutron stars asymmetric with respect to their rotation axis are potential sources of continuous gravitational waves for ground-based interferometric detectors. In the case of known pulsars a fully coherent search, based on matched filtering, which uses the position and rotational parameters obtained from electromagnetic observations, can be carried out. Matched filtering maximizes the signalto- noise (SNR) ratio, but a large sensitivity loss is expected in case of even a very small mismatch between the assumed and the true signal parameters. For this reason, narrow-band analysis methods have been developed, allowing a fully coherent search for gravitational waves from known pulsars over a fraction of a hertz and several spin-down values. In this paper we describe a narrow-band search of 11 pulsars using data from Advanced LIGO’s first observing run. Although we have found several initial outliers, further studies show no significant evidence for the presence of a gravitational wave signal. Finally, we have placed upper limits on the signal strain amplitude lower than the spin-down limit for 5 of the 11 targets over the bands searched; in the case of J1813-1749 the spin-down limit has been beaten for the first time. For an additional 3 targets, the median upper limit across the search bands is below the spin-down limit. This is the most sensitive narrow-band search for continuous gravitational waves carried out so far

    Enhancing satiety and aerobic performance with beer microparticles-based non-alcoholic drinks: exploring dose and duration effects

    Beer is an alcoholic beverage, rich in carbohydrates, amino acids, vitamins and polyphenols, consumed worldwide as a social drink. There is a large number of beer styles which depends on the ingredients and brewing process. The consumption of beer as a fluid replacement after sport practice is a current discussion in literature. A non-alcoholic pale-ale microparticles-based beverage (PABM) have been previously designed, however, its phenolic profile and ergogenic effect remain unknown. Thus, this study aims to verify the ergogenic potential (increase of running performance) of PAMB in male Wistar rats. Beer microparticles were obtained by spray drying and beverages with different concentrations were prepared in water. Wistar rats were subjected to a training protocol on a treadmill (5 times/week, 60 min/day) and daily intake of PABM (20 mg.kg-1 or 200 mg.kg-1) or water by gavage. Chlorogenic acid was found to be the main component in the phenolic profile (12.28 mg·g-1) of PABM analyzed with high-performance liquid chromatography and mass spectrometry. An increase in the aerobic performance was observed after 4 weeks in the 20 mg.kg-1 group, but the same dose after 8 weeks and a higher dose (200 mg.kg-1) blunted this effect. A higher dose was also related to decrease in food intake. These data suggest that PABM can improve satiety and aerobic performance, but its effect depends on the dose and time of consumption
