Built and natural environment correlates of physical activity of adults living in rural areas: a systematic review.

BACKGROUND: According to social-ecological models, the built and natural environment has the potential to facilitate or hinder physical activity (PA). While this potential is well researched in urban areas, a current systematic review of how the built and natural environment is related to PA in rural areas is lacking. METHODS: We searched five databases and included studies for adults (18-65 years) living in rural areas. We included quantitative studies investigating the association between any self-reported or objectively measured characteristic of the built or natural environment and any type of self-reported or objectively measured PA, and qualitative studies that reported on features of the built or natural environment perceived as barriers to or facilitators of PA by the participants. Screening for eligibility and quality assessment (using the Standard Quality Assessment Criteria for Evaluating Primary Research Papers from a Variety of Fields) were done in duplicate. We used a narrative approach to synthesize the results. RESULTS: Of 2432 non-duplicate records, 51 quantitative and 19 qualitative studies were included. Convincing positive relationships were found between the availability and accessibility of places for exercise and recreation and leisure-time PA as well as between the overall environment and leisure-time PA. Possible positive associations were found between the overall environment and total and transport-related PA, between greenness/natural environment and total PA, between cycling infrastructure and aesthetics and MVPA, and between pedestrian infrastructure and total walking. A possible negative relationship was found between safety and security and total walking. Qualitative studies complemented several environmental facilitators (facilities for exercise and recreation, sidewalks or streets with low traffic, attractive natural environment) and barriers (lack of facilities and destinations, lack of sidewalks, speeding traffic and high traffic volumes, lack of street lighting). CONCLUSIONS: Research investigating the relationship between the built and natural environment and PA behaviors of adults living in rural areas is still limited and there is a need for more high-quality and longitudinal studies. However, our most positive findings indicate that investing in places for exercise and recreation, a safe infrastructure for active transport, and nature-based activities are possible strategies that should be considered to address low levels of PA in rural adults.

Valuing the health benefits of nature-based recreational physical activity in England.

Physical activity (PA) reduces the risk of several non-communicable diseases (NCDs). Natural environments support recreational PA. Using data including a representative cross-sectional survey of the English population, we estimated the annual value of nature-based PA conducted in England in 2019 in terms of avoided healthcare and societal costs of disease. Population-representative data from the Monitor of Engagement with the Natural Environment (MENE) survey (n = 47,580; representing 44,386,756) were used to estimate the weekly volume of nature-based recreational PA by adults in England in 2019. We used epidemiological dose-response data to calculate incident cases of six NCDs (ischaemic heart disease (IHD), ischaemic stroke (IS), type 2 diabetes (T2D), colon cancer (CC), breast cancer (BC) and major depressive disorder (MDD)) prevented through nature-based PA, and estimated associated savings using published costs of healthcare, informal care and productivity losses. We investigated additional savings resulting from hypothetical increases in: (a) visitor PA and (b) visitor numbers. In 2019, 22million adults > 16 years of age in England visited natural environments at least weekly. At reported volumes of nature-based PA, we estimated that 550 cases of IHD, 168 cases of IS, 1,410 cases of T2D, 41 cases of CC, 37 cases of BC and 10,552 cases of MDD were prevented, creating annual savings of £108.7million (95 % uncertainty interval: £70.3million; £150.3million). Nature-based recreational PA in England results in reduced burden of disease and considerable annual savings through prevention of priority NCDs. Strategies that increase nature-based PA could lead to further reductions in the societal burden of NCDs.

Recreio e Educação Física: possibilidades para a prática pedagógica de professores de Educação Física Escolar / School recess and Physical Education: possibilities for the pedagogical practice of school Physical Education Teachers / Recreo y Educación Física: posibilidades para la práctica pedagógica de los profesores de Educación Física Escolar

Neste estudo, tematizamos o recreio escolar e seus desdobramentos para além de seu tempo, procurando compreendê-lo como um momento da rotina escolar conectado à função social da escola, bem como um momento muito fecundo, que pode enriquecer a atuação do(a) professor(a) de Educação Física (EF). Através de um ensaio teórico, apontamos que o tempo de recreio pode representar uma referência para a EF escolar e para todos os seus atores, professores, alunos e alunas, estimulando novos modos de inserir as práticas corporais no âmbito da escola, bem como para além dela (AU).

In this study, we have addressed the school recess and its unfoldings beyond its time span. We endevored to understand the school recess as part of the school routine, connected with the social function of the school. We have considered this time as a fruitful moment that can enrich the Physical Education teacher's performance. Through a theoretical essay, we have tried to demonstrate that recess time can represent a reference for school PE and for all its actors, such as teachers, pupils and students. It might also stimulate new ways of inserting body practices within the school (AU).

En este estudio nos enfocamos en el recreo escolar y sus desarrollos más allá de su tiempo, tratando de entenderlo como un momento de la rutina escolar, conectado a la función social de la escuela, así como un momento muy fructífero, que puede enriquecer la actuación del profesor de Educación Física (EF). A través de un ensayo teórico señalamos que el tiempo de recreo puede representar una referencia para la EF escolar y para todos sus actores, docentes, alumnos y alumnas, estimulando nuevas formas de insertar prácticas corporales en el ámbito escolar, así como, más allá de ella (AU).

Microplastic surface retention and mobility on hiking trails.

Hiking and trail running are a source of microplastic (MP) pollution on recreational trails in wilderness and conservation areas; however, the fate of MPs deposited on trails is poorly understood as MP mobility on such surfaces has not yet been examined. In this study, we simulated heavy rainfall (100 mm/h) on trail surfaces with existing MP pollution (in situ MPs) and spiked with 99 ± 2 rubber MPs (100-940 µm). Runoff was collected for 15 min and spiked and in situ MPs were quantified. Hydrological, erosional and microplastic responses were evaluated in relation to slope, bulk density, soil moisture and surface condition indicators, including amounts and types of surface cover and soil physical attributes. The MPs were largely immobile, with 85-100% of spiked MPs retained on trail surfaces. In situ MPs were detected in the trail runoff, with the majority being polyurethane, polypropylene and polyester. Microplastic movement was primarily influenced by hydrological effects, and analysis indicated the main explanatory variable was total runoff volume, followed by soil slaking. Trail sections with at least 15% herbaceous cover or a layer of loose alluvium had higher MP retention. Areas of resource accrual may be preferentially enriched, suggesting MPs from outdoor recreation may be concentrated on and adjacent to recreational trails. Microplastics deposited on trails may have long term implications for biodiversity and ecosystem functioning in wilderness and conservation areas, particularly around the trail corridor.

Alignment philosophy influences trochlea recreation in total knee arthroplasty: a comparative study using image-based robotic technology.

PURPOSE: The ability of kinematic alignment (KA) to consistently restore trochlea anatomy in total knee arthroplasty (TKA) is unknown despite recreation of constitutional anatomy being its rationale for use. The purpose of this study was to assess if alignment choice in TKA effects the ability to restore the native trochlea groove. METHODS: One hundred and twenty-two consecutive patients undergoing robotic-assisted TKA using the MAKO image-based robotic platform had simulated femoral components placed according to kinematic, mechanical and functional alignment principals. Implant position and trochlea restoration between groups were compared. Restoration was assessed by shift (medial-lateral) and depth relative to the native groove from three consistent points; full extension (0°), mid-flexion (30°-40°) and deep flexion (70°-80°). RESULTS: Three hundred and sixty-six alignment options were analysed. Femoral alignment was significantly different between groups. Of KA, 13.1% compared to 3.3% of FA plans were outside safe coronal boundaries. The trochlear groove was translated the most by MA compared to KA and FA (full extension, MA 7.84 ± 1.99 mm lateral to the native groove, KA 6.40 ± 2.43 mm and FA 6.88 ± 1.74 mm, p ≤ 0.001). In full extension, FA most closely restored the trochlear groove depth in all three positions of flexion. CONCLUSION: Alignment philosophy led to significant differences in trochlea groove recreation. A kinematically placed femoral component led to positioning considered unsafe in over 13% of cases. A functionally placed femoral component most closely restored trochlea depth in all three positions of flexion.

Processos de reflexividade dos psicólogos do esporte e coaches: um estudo fenomenológico / Reflexivity processes of sport psychologists and coaches: a phenomenological study / Procesos de reflexividad de psicólogos del deporte y coaches: un estudio fenomenológico

O objetivo desta pesquisa é identificar e compreender fenomenologicamente, por meio de relato de Psicólogos de Esporte (PE) e de Coaches, em sua vivência prática, como ocorrem os processos reflexivos em sua atuação, conforme apreendidos a partir de relatos de experiências. O método de investigação escolhido foi a fenomenologia, pois oferece os recursos necessários para tal mergulho junto à experiência reflexiva. A amostra intencional foi delineada por PE e Coaches (profissionais de Educação Física que recorrem ao Coaching) em atividade em esportes de alto rendimento, que tenham atuado ou estejam atuando em modalidades esportivas coletivas e/ou individuais. Realizaram-se nove entrevistas (cinco com PE, quatro com Coaches). O acesso ao objeto desse estudo se deu por meio de entrevistas em profundidade e semiestruturadas, orientadas pela escuta suspensiva. As questões disparadoras foram formuladas com base no Procedimento Estruturado de Reflexão adaptado. Para análise das entrevistas, realizou-se uma síntese de cada relato, seguindo-se de cruzamento intencional. Como resultados, percebeu-se que PE e Coaches trazem algumas similaridades no que se refere aos modos de refletir sobre sua prática. No entanto, as experiências que eles fazem desses processos reflexivos é que podem tomar rumos distintos. Os(as) PE amparam-se na regulamentação da profissão e resguardam-se em seus apontamentos, trazendo suas experiências e reflexões sobre os processos vividos. Os(as) Coaches trazem em suas explanações um trabalho coerente, organizado e compatível com o método do Coaching. Problematizar os processos reflexivos desses profissionais permite diferenciar qualitativa e eticamente suas atuações, possibilitando o fomento multiprofissional no esporte.(AU)

The aim of this study consists in phenomenologically identifying and understanding, by the report of Sport Psychologists (SP) and coaches, in their practical experience, how would be the reflexive processes that take place in their performance, as learned from reports of their experiences. The research method chosen was phenomenology, since it offers the necessary resources for such a dive along with the reflective experience. The intentional sample was outlined by SP and coaches (Physical Education professionals who use coaching) active in high performance sports, who have or are working in collective and/or individual sports. Nine interviews were conducted (five with SP, four with coaches). Access to the object of this study took place by in-depth and semi-structured interviews, guided by suspensive listening. The triggering questions were formulated based on the adapted Structured Reflection Procedure. For the analysis of the interviews, a synthesis of each report was carried out, followed by the intentional crossing. As results, it was noticed that SP and coaches bring some similarities regarding the ways of reflecting on their practice. However, their experiences of these reflective processes are that they can take different directions. The SP are based on the regulation of the profession and guard themselves in their notes, bringing their experiences and reflections on the processes experienced. Coaches bring in their explanations a coherent, organized, and compatible work with the coaching method. Problematizing the reflective processes of these professionals allows to differentiate their actuation qualitatively and ethically, making the multiprofessional phenomenon in sport possible.(AU)

El objetivo de este estudio consiste en identificar y comprender fenomenológicamente, a partir de la experiencia práctica de psicólogos del deporte (PD) y coaches, cómo serían los procesos reflexivos que se llevan a cabo en su rendimiento, tal y como se desprende de los informes de experiencias. El método de investigación elegido fue la fenomenología, ya que ofrece los recursos necesarios junto con la experiencia. La muestra intencional fue delineada por PD y coaches (profesionales de la educación física que utilizan el coaching) activos en deportes de alto rendimiento, que tienen o están trabajando en deportes colectivos e/o individuales. Se realizaron nueve entrevistas (cinco con PD, cuatro con coaches). El acceso al objeto de este estudio fue entrevistas en profundidad y semiestructuradas, guiadas por escuchas suspensivas. Las preguntas se formularon desde el procedimiento de reflexión estructurado adaptado. Para el análisis de las entrevistas, se hizo una síntesis de cada informe, seguida del cruce intencional. Como resultados, se notó que los PD y coaches tienen algunas similitudes con respecto a las formas de reflexionar sobre su práctica. Sin embargo, las experiencias que hacen de estos procesos pueden tomar diferentes direcciones. Los(las) PD se basan en la regulación de la profesión y se protegen en sus notas, aportando sus experiencias y reflexiones sobre los procesos vividos. Los(las) coaches plantean en sus explicaciones un trabajo coherente, organizado y compatible con el método de Coaching. Problematizar los procesos reflexivos de estos profesionales permite diferenciar sus acciones de manera cualitativa y ética, además de posibilitar la promoción multiprofesional en el deporte.(AU)

Orientação a pais por chamadas de áudio durante a pandemia de covid-19 / Support for parents via audio calls during the covid-19 pandemic / Orientación de los padres mediante llamadas de audio durante la pandemia de covid-19

O distanciamento social ocasionado pela pandemia de Covid-19 levou a profundas mudanças na rotina das famílias com crianças pequenas, aumentando o estresse no ambiente doméstico. Este estudo analisou a experiência de planejamento e implementação de um projeto de extensão universitária que ofereceu orientação a pais com filhos de 0 a 11 anos por meio de chamadas de áudio durante a pandemia. O protocolo de atendimento foi desenvolvido para atender às necessidades de famílias de baixa renda e listava problemas específicos relacionados ao confinamento em casa e ao fechamento das escolas seguidos por uma variedade de estratégias de enfrentamento. A análise de 223 queixas relatadas pelos usuários em 130 ligações revelou que 94% dos problemas referidos pelos pais foram contemplados pelo protocolo de atendimento e estavam relacionados aos problemas externalizantes (39%) ou internalizantes (26%) das crianças ou ao declínio do bem-estar subjetivo dos pais (29%). Serviços de apoio devem orientar os pais quanto ao uso de práticas responsivas e assertivas que promovam o bem-estar emocional da criança e estabeleçam expectativas comportamentais em contextos estressantes. A diminuição dos conflitos entre pais e filhos resultante do uso dessas estratégias tende a reduzir o sofrimento dos pais, aumentando sua sensação de bem-estar subjetivo. Recomenda-se ampla divulgação dessas iniciativas e seguimento dos casos.(AU)

The social distancing the COVID-19 pandemic entailed has led to profound changes in the routine of families with young children, increasing stress in the home environment. This study analyzed the experience of planning and implementing a university extension program that offered support to parents with children from 0 to 11 years old via audio calls during the COVID-19 pandemic. The service protocol was developed to meet the needs of low-income families and listed specific problems related to home confinement and school closure followed by a variety of coping strategies. The analysis of 223 complaints reported by users in 130 calls revealed that 94% of the problems reported by parents were addressed by the protocol and were related to children's externalizing (39%) or internalizing (26%) problems or to the decline in parents' subjective well-being (29%). Support services should guide parents on the use of responsive and assertive practices that promote the child's emotional well-being and set behavioral expectations in stressful contexts. The reduction in conflicts between parents and children resulting from the use of these strategies tends to reduce parents' suffering, increasing their sense of subjective well-being. Wide dissemination of these initiatives and case follow-up are recommended.(AU)

La distancia social causada por la pandemia de COVID-19 condujo a cambios profundos en la rutina de las familias con niños pequeños, aumentando el estrés en el entorno del hogar. Este estudio analizó la experiencia de planificar e implementar un proyecto de extensión universitaria que ofreció orientación a los padres con niños de cero a 11 años a través de llamadas de audio durante la pandemia COVID-19. El protocolo de atención se desarrolló para satisfacer las necesidades de las familias de bajos ingresos y enumeró problemas específicos relacionados con el confinamiento en el hogar y el cierre de la escuela, seguido de una variedad de estrategias de afrontamiento. El análisis de 223 quejas informadas por los usuarios en 130 llamadas reveló que el 94% de los problemas informados por los padres fueron abordados por el protocolo de atención y estaban relacionados con los problemas de externalización (39%) o internalización (26%) de los niños o la disminución del bienestar subjetivo de los padres (29%). Los servicios de apoyo deberían aconsejar a los padres sobre el uso de prácticas receptivas y asertivas que promuevan el bienestar emocional del niño y establezcan expectativas de comportamiento en contextos estresantes. La reducción de los conflictos entre padres e hijos como resultado del uso de estas estrategias tiende a reducir el sufrimiento de los padres, aumentando su sensación de bienestar subjetivo. Se recomienda una amplia difusión de estas iniciativas y seguimiento de casos.(AU)

A experiência intersubjetiva na ludoterapia humanista sob uma perspectiva fenomenológica / The intersubjective experience in humanistic play therapy from the standpoint of phenomenology / La experiencia intersubjetiva en la ludoterapia humanista desde una perspectiva fenomenológica

Esta pesquisa qualitativa objetivou compreender, fenomenologicamente, a experiência vivida por psicoterapeutas e crianças no acontecer clínico da ludoterapia humanista. Foram realizados 26 encontros dialógicos individuais com nove psicoterapeutas e sete crianças, registrados pela pesquisadora na forma de Narrativas Compreensivas que incluíram suas impressões impactadas subjetivamente pelas falas e expressões corporais dos participantes. A análise fenomenológica culminou com a escrita de uma Narrativa Síntese. Os resultados indicam que a relação psicoterapêutica é percebida como: facilitadora do crescimento psicológico da criança; intensificadora do fluxo de mudanças ao dinamizar os processos pessoais infantis; geradora de motivação na criança para a relação interpessoal, a partir do envolvimento subjetivo do terapeuta; potencializadora da tomada de consciência com base na corporeidade; propiciadora da integração de experiências por meio do brincar; reveladora das singularidades individuais, catalisando o desenvolvimento; e, por fim, benéfica à atualização de significados e sentidos da experiência pessoal e relacional. Evidenciou-se, entre os psicoterapeutas, uma concepção da ludoterapia humanista que prioriza a compreensão dirigida ao estilo próprio de cada cliente em relação aos modos de sentir e expressar-se no mundo e à estruturação do processo psicoterapêutico a partir do relacionamento com a criança. Concluiu-se, assim, que a experiência desse tipo de relação interpessoal facilita a constituição na criança de singularidades que imprimem um sentido existencial próprio ao seu mundo de relações e historicidade. A relevância do processo psicoterapêutico para o crescimento psicológico da criança apresentou-se também pelo seu caráter psicoprofilático, reverberado no encadeamento de processos associados à experiência pessoal dela.(AU)

This qualitative research aimed to understand, phenomenologically, the lived experience of psychotherapists and children in the clinical event of humanistic play therapy. A total of 26 individual dialogical encounters were held with nine psychotherapists and seven children, registered in the form of Comprehensive Narratives by the researcher, which included her subjectively impacted impressions about the participants' speeches and body expressions. The phenomenological analysis culminated in a Synthesis Narrative. The results demonstrate that the psychotherapeutic relationship is perceived as: facilitating the child's psychological growth; intensifying the flow of change by streamlining children's personal processes; generating motivation for the child to get involved with interpersonal relationship, based on the subjective involvement of the therapist; potentiating awareness raising based on the corporeality; enabling the integration of experiences by playing; revealing the uniqueness, catalyzing development; and, finally, benefiting the updating of meanings and senses of personal and relational experience. A conception of humanistic play therapy became evident among the psychotherapists, which prioritizes the understanding directed to the own way of each client regarding how to feel and express themselves in the world and the structuring of the psychotherapeutic process based on the relationship with the child. Thus, it was concluded that the experience of this interpersonal relationship facilitates the constitution in the child of singularities that bring their own existential meaning to their world of relationships and historicity. The relevance of the psychotherapeutic process for the child's psychological growth was also shown by the psycho-prophylactic character reverberated in the processes associated with the child's personal experience.(AU)

Esta investigación cualitativa tuvo por objetivo comprender, fenomenológicamente, la experiencia vivida por psicoterapeutas y niños en ludoterapia de orientación humanista. La investigadora desarrolló 26 conversaciones dialógicas individuales con nueve psicoterapeutas y siete niños, registradas como narrativas comprensivas que incluyeron sus impresiones impactadas subjetivamente por los discursos y expresiones corporales de los participantes. El análisis fenomenológico culminó con una síntesis narrativa. Los resultados demuestran que la relación psicoterapéutica se percibe como facilitadora del crecimiento psicológico del niño; intensificadora del flujo de cambio, optimizando su procesos personales; generadora de motivación para que el niño se involucre en la relación interpersonal a partir del envolvimiento subjetivo del terapeuta; potenciadora de la toma de conciencia a partir de la corporeidad; propiciadora de la integración de las experiencias por medio del juego; reveladora de singularidades individuales al catalizar el desarrollo; y beneficiosa para actualizar los significados y sentidos de la experiencia personal e relacional. Entre los psicoterapeutas se hizo evidente una concepción de ludoterapia humanista que prima por comprender la forma propia del cliente de sentirse y expresarse y la estructuración del proceso psicoterapéutico a partir de la relación con el niño. Se concluyó que la vivencia de este tipo de relación facilita la constitución en el niño de singularidades que le aportan un sentido existencial a su mundo de relación e historicidad. La relevancia del proceso psicoterapéutico para el crecimiento psicológico también se mostró por su carácter psicoprofiláctico, que reverberó en la cadena de procesos asociados con la experiencia personal del niño.(AU)

Evidências de validade do teste informatizado para avaliação das funções executivas / Evidence of validity of the computerized test for evaluating executive functions / Evidencia de validez de la prueba computarizada para evaluación de funciones ejecutivas

Funções executivas (FE) referem-se ao conjunto de habilidades que, de forma integrada, coordenam o comportamento e a cognição. Assim, o comprometimento no desenvolvimento das FE está ligado a vários desfechos negativos ao longo da vida. Portanto, a avaliação dessas habilidades na infância é essencial para identificar e prevenir prejuízos na vida adulta. Este estudo teve como objetivo investigar evidências de validade do Teste Informatizado para Avaliação das Funções Executivas (Tafe) pelo critério de idade e pelo padrão de correlação entre medidas do TAFE e outras medidas de FE. Para isso, foi utilizada uma amostra de 51 crianças, entre 4 e 10 anos de idade, matriculadas em uma escola privada na cidade de Goiânia (GO), da pré-escola ao 4º ano do ensino fundamental. Como instrumentos, foram utilizados, além do Tafe, as tarefas de Bloco de Corsi, Teste de Trilhas A e B, Teste de Trilhas Pré-Escolares, Teste de Stroop Pré-Escolares e Subteste Dígitos da Escala Wechsler de Inteligência. Foram conduzidas análises estatísticas Kruskal Wallis para verificar a evidência de validade por relação com idade e análises de correlação não paramétrica de Spearman para avaliar as evidências de validade convergente. O instrumento investigado mostrou-se efetivo para discriminar entre as diferentes faixas etárias, assim, sensível ao desenvolvimento das FE. Os resultados obtidos no Tafe correlacionaram-se aos obtidos em outros testes que também avaliaram FE, mostrando claros padrões de convergência. Logo, as análises dos resultados fornecem evidências de validade ao Tafe, derivadas a partir de diferentes estratégias de investigação.(AU)

Executive functions (EF) refer to the set of skills that, in an integrated way, coordinate behavior and cognition. Thus, the commitment in developing EF is linked to several negative outcomes throughout life. Therefore, the assessment of these abilities in childhood is essential to identify and prevent possible harm in adult life. This study aimed to investigate evidences of validity of the Computerized Test for Evaluation of Executive Functions (TAFE) by the age criterion and by the pattern of correlation between TAFE measures and other EF measures. To this end, a sample of 51 children, between 4 and 10 years old, enrolled in a private school in the municipality of Goiânia (GO), from preschool to the 4th year of elementary school, was used. As instruments, in addition to TAFE, the tasks of Corsi Block, Trails Test A and B, Preschool Trails Test, Preschool Stroop Test and the Digits Subtest of the Wechsler Intelligence Scale were used. Kruskal Wallis statistical analyzes were conducted to verify the evidence of validity by age criteria and Spearman's nonparametric correlation analysis to assess evidence of convergent validation. The instrument investigated was effective to discriminate between different age groups, thus being sensitive to the development of EF. The results obtained in TAFE were correlated with those obtained in other tests that also assess FE, showing patterns of convergence. Therefore, the analysis of the results provides validation evidence to TAFE, derived from different investigation methods.(AU)

Las funciones ejecutivas (FE) se refieren al conjunto de habilidades que coordinan la conducta y la cognición. Así, el deterioro en el desarrollo de FE está relacionado con varios resultados negativos durante la vida. Por tanto, la valoración de estas habilidades en la infancia es fundamental para identificar y prevenir posibles daños en la vida adulta. Este estudio tuvo como objetivo investigar la evidencia de validez de la Prueba Computarizada para Evaluación de Funciones Ejecutivas (Tafe) por el criterio de edad y convergencia entre las medidas Tafe y otras medidas de FE. Para ello, se utilizó una muestra de 51 niños, de entre 4 y 10 años de edad, matriculados en un colegio privado de Goiânia (Goiás, Brasil) desde la preescolar hasta 4.º de primaria. Como instrumentos, además del Tafe, se utilizaron las tareas de Bloque de Corsi, el Test de los senderos A y B, el Test de los Senderos Preescolares, el Test de Stroop Preescolar y la Subprueba de Dígitos de la Escala Wechsler de Inteligencia. Se realizaron análisis estadísticos de Kruskal Wallis para verificar la validez por criterios de edad y análisis de correlación no-paramétrica de Spearman para evaluar la evidencia de validez convergente. Tafe demostró ser efectivo para discriminar entre diferentes grupos de edad, así es sensible al desarrollo de FE. Los resultados en Tafe se correlacionaron con los obtenidos en otras pruebas de FE, lo que muestra claros patrones de convergencia. Por tanto, el análisis aporta evidencias de validez para Tafe, derivadas de diferentes estrategias de investigación.(AU)

The state mindfulness scale for physical activity: further psychometrics properties / Escala de estado de mindfulness para atividade física: novas propriedades psicométricas / Escala de mindfulness en la actividad física: nuevas propiedades psicométricas

Mindfulness has been defined as attention and awareness to the present with an attitude of openness, non-judgment, and acceptance. It is suggested that mindfulness can positively influence experiences in sports and physical activity, increasing adherence to these activities. This study aimed to examine new psychometric properties of the State Mindfulness Scale for Physical Activity (SMS-PA) using classical and modern testing theories among Brazilian sport and exercise practitioners. Two studies were conducted. In the first, with 617 Brazilian sports practitioners, confirmatory factor analysis supported the bifactor structure of the SMS-PA composed of two specific (mental and body mindfulness) and one general factor (state mindfulness), which did not vary among genders. The Rasch Rating Scale Model (RSM) supported essential one-dimensionality indicated by the general factor with good item fit statistics (infit/outfit 0.62-1.27). The model presented a good level of Rasch reliability (0.85), and the items difficulty estimation provided an understanding of the continuum represented by their content. In the second study, with 249 Brazilian exercise practitioners, the structural equation modeling showed that Body Mindfulness was associated with positive outcomes (positive affect and satisfaction with practice). The mediation analysis showed that people with higher levels of Body mindfulness tend to experience greater levels of Positive Affect and, consequently, greater Satisfaction with exercises. The results suggest that the Brazilian version of the SMS-PA is an appropriate measure of the state of mindfulness.(AU)

Mindfulness pode ser definido como atenção e consciência no momento presente com uma atitude de abertura, não julgamento e aceitação. A literatura sugere que o mindfulness pode influenciar positivamente experiências no esporte e atividade física e pode exercer um papel na adesão a essas atividades. Este estudo teve como objetivo investigar novas propriedades psicométricas da State Mindulness Sacale for Physical Activity (SMS-PA) utilizando as teorias clássicas e modernas dos testes em praticantes de exercício físico e esporte brasileiros. Dois estudos foram conduzidos. No primeiro, com 617 brasileiros praticantes de esporte, a Análise Fatorial Confirmatória (AFC) demonstrou adequação à estrutura bifatorial da SMS-PA composta por dois fatores específicos (mindfulness mental e físico) e um fator geral (estado de mindfulness), que apresentou invariância entre sexos. A Rasch Rating Scale Model (RSM) corroborou a unidimensionalidade essencial indicada pelo fator geral com bons índices de ajustes (infit/outfit 0.62 -1.27). O modelo apresentou bom nível de precisão Rasch (.85), e a estimação de dificuldade dos itens possibilitou compreensão do continuum representado pelo conteúdo dos itens. No segundo estudo, com 249 brasileiros praticantes de esporte, a Modelagem de Equações Estruturais demonstrou que o mindfulness físico esteve associado a afetos positivos e satisfação com a prática. A análise de mediação mostrou que pessoas com níveis altos de mindfulness físico tendem a apresentar níveis mais elevados de afeto positivo e, consequentemente, níveis mais elevados de satisfação com a prática. Os resultados sugerem que a versão brasileira do SMS-PA é uma medida apropriada do estado de mindfulness para atividades físicas.(AU)

La atención plena puede definirse como la atención y la conciencia en el momento presente con una actitud de apertura, no juicio y aceptación. La literatura sugiere que el mindfulness puede influir positivamente en las experiencias en el deporte y en la actividad física, además de desempeñar un papel en la adherencia a estas actividades. Este estudio tuvo como objetivo investigar nuevas propiedades psicométricas de la State Mindfulness Scale for Physical Activity (SMS-PA) utilizando las teorías clásicas y modernas de las pruebas en practicantes de ejercicio físico y de deporte en Brasil. Para ello, se realizaron dos estudios. En el primer, participaron 617 practicantes de deporte brasileños, y el análisis factorial confirmatorio (AFC) demostró adecuación en la estructura bifactorial de la SMS-PA, compuesta por dos factores específicos (mindfulness mental y físico) y un factor general (estado de mindfulness), que mostró invarianza entre sexos. El Rasch Rating Scale Model (RSM) corroboró la unidimensionalidad esencial indicada por el factor general con buenos índices de ajuste (infit/outfit 0,62-1,27). El modelo mostró un buen nivel de precisión de Rasch (.85), y la estimación de la dificultad de los ítems permitió comprender el continuo representado por el contenido de estos. En el segundo estudio, con 249 practicantes de deporte, el modelo de ecuaciones estructurales mostró que el mindfulness físico estaba asociado a resultados positivos (afecto positivo y satisfacción con la práctica). El análisis de mediación reveló que las personas con altos niveles de mindfulness físico tendían a tener mayores niveles de afecto positivo y, en consecuencia, mayores niveles de satisfacción con la práctica. Los resultados sugieren que la versión brasileña de la SMS-PA es una medida adecuada de mindfulness.(AU)

Apropriação dos espaços urbanos na infância e na velhice em Brasília (DF) / Occupation of urban spaces in childhood and old age in Brasilia, Brazil / Apropiación de espacios urbanos en la infancia y en la vejez en Brasília, Brasil

Os estudos sobre as relações mútuas entre as pessoas e o ambiente buscam subsidiar melhorias no contexto urbano a partir de métodos e técnicas pautados na compreensão do uso de espaços públicos e privados. A crescente demanda pela promoção de ambientes amigáveis para idosos e crianças nos cenários urbanos direcionou esta pesquisa e elencou dois componentes: o panorama relativo à população local e o arcabouço teórico da psicologia ambiental. Para tanto, buscou-se identificar as principais atividades realizadas por crianças e idosos em seus respectivos locais de moradia. Foram avaliados os principais usos e atividades desses dois grupos, em duas vizinhanças, diferenciando-os de acordo com suas especificidades em termos de demandas individuais e ambientais. As observações sistemáticas a partir da técnica de mapeamento comportamental centrado no lugar (MCCL) ocorreram na cidade de Brasília, Distrito Federal (DF) e permitiram compreender o processo de apropriação dos espaços na infância e na velhice e suas repercussões em termos da congruência pessoa-ambiente. Cada um destes setores organizados a partir de elementos específicos direciona as ações dos participantes para determinados tipos de comportamentos, observados de maneira a compor um roteiro em que a brincadeira (lazer ativo) surge como central na infância e a caminhada (circulação) como mais potente para a população idosa. Os resultados demonstram que o diálogo entre a psicologia ambiental e a ciência do desenvolvimento humano tem sido bastante profícuo e tem contribuído para a compreensão de aspectos da relação pessoa-ambiente em diferentes momentos do ciclo de vida.(AU)

Studies on the mutual relations between people and the environment seek to support improvements in the urban context from methods and techniques based on understanding the use of public and private spaces. The growing demand for the promotion of friendly urban environments for older people and children guided this research, with two notable components: the panorama related to the local population and the theoretical framework of Environmental Psychology. Therefore, we sought to identify the main activities carried out by children and older people in their respective dwellings. The main uses and activities of these two groups were evaluated in two neighborhoods, differentiating them according to their specificities in terms of individual and environmental demands. Systematic observations using the place-centered behavioral mapping technique took place in the city of Brasília, Federal District, and allowed us to understand the process of appropriation of spaces in childhood and old age and its repercussions in terms of person-environment congruence. Each of these sectors, organized from specific elements, directs the participants' actions towards certain types of behavior, observed in order to compose a script in which playing (active leisure) emerges as central in childhood and walking (circulation) as more potent for the older people. The results demonstrated that the dialogue between environmental psychology and the science of human development has been very fruitful and has contributed to the understanding of aspects of the person-environment relationship at different times in the life cycle.(AU)

Los resultados demuestran que el diálogo entre la Psicología Ambiental y la ciencia del desarrollo humano ha sido muy fructífero y ha contribuido a la comprensión de aspectos de la relación persona-entorno en diferentes momentos del ciclo de vida.(AU)

Juegos tradicionales para niños con discapacidad visual: un conocimiento necesario en educación médica / Traditional games for visually impaired children: a necessary knowledge in medical education

Fundamento: los juegos tradicionales resultan motivantes y de fácil ejecución para los escolares con necesidades educativas especiales porque favorecen la movilidad y orientación espacial de niños con discapacidad visual. Objetivo: proponer un grupo de juegos tradicionales adaptados para mejorar la movilidad y orientación espacial de niños con discapacidad visual en la Escuela Especial "Fructuoso Rodríguez" de Santa Clara, Villa Clara, Cuba. Métodos: se realizó un estudio descriptivo transversal, entre los meses de mayo-septiembre de 2021. Se emplearon métodos teóricos: analítico-sintético, inductivo-deductivo e histórico-lógico; y empíricos: análisis de documentos, observación, cuestionario y entrevista. Resultados: el diagnóstico realizado corroboró que los sujetos estudiados presentaban dificultades en la movilidad y la orientación espacial; desconfianza, inseguridad y pocas iniciativas relacionadas con la recreación en su cotidianeidad familiar, por lo que se adaptaron 10 juegos tradicionales conocidos, pero poco jugados por los niños con discapacidad visual, con el fin de alcanzar otras vías que contribuyan a mejorar su movilidad y orientación espacial, luego de una etapa de confinamiento provocada por la Covid-19. Conclusiones: la propuesta de juegos tradicionales adaptados responde a la necesidad detectada y potencia la recreación e inclusión de estos infantes en actividades escolares y extraescolares después de la pandemia.

Background: traditional games are motivating and easy to play for schoolchildren with special educational needs because they favor the mobility and spatial orientation of visually impaired children. Objective: to propose a group of traditional games adapted to improve the mobility and spatial orientation of visually impaired children at "Fructuoso Rodríguez" Special School in Santa Clara, Villa Clara, Cuba. Methods: a cross-sectional descriptive study was carried out, from May to September 2021. Theoretical methods were used: analytical-synthetic, inductive-deductive and historical-logical; and empirical ones: document analysis, observation, questionnaire and interview. Results: the diagnosis made corroborated that the subjects studied presented difficulties in mobility and spatial orientation; distrust, insecurity and few initiatives related to recreation in their family daily life, for which 10 known traditional games were adapted, but little played by children with visual disabilities, in order to reach other ways that contribute to improving their mobility and orientation space, after a stage of confinement caused by Covid-19. Conclusions: the proposal of adapted traditional games responds to the detected need and enhances the recreation and inclusion of these infants in school and extracurricular activities after the pandemic.

Psicanálise e educação: crianças e educadores brincando com palavras / Psychoanalysis and education: children and educators playing with words / Psicoanálisis y educación: niños y educadores jugando com palabras

Este artigo tem como objetivo compreender as experiências do brincar a partir de um grupo de crianças e seus educadores, em uma Comunidade de Aprendizagem, situada no Distrito Federal (DF). Como fundamentação teórica e metodológica, recorre-se, principalmente, aos estudos psicanalíticos de Freud e de Winnicott. A pesquisa de campo consistiu em dois dias de observação participante; quatro oficinas de rabiscos com uma turma de crianças - com idades entre oito e 12 anos - e sua educadora; e uma roda de conversa com educadores. A ênfase é dada, neste texto, nas vivências da segunda oficina e em trechos da roda de conversa, explorando a capacidade de criar e de brincar com as palavras. Com isso, foi possível ressaltar a importância de um brincar criativo e espontâneo nas relações humanas. A conclusão é que este brincar não se restringe à infância, por se tratar de uma experiência própria ao humano, sendo necessário que os espaços escolares e comunitários estejam abertos à sua manifestação e ampliação. (AU)

This article aims to understand the experiences of playing from a group of children and their educators, in a Learning Community, located in the Federal District (DF). As a theoretical and methodological basis, we use mainly the psychoanalytical studies of Freud and Winnicott. The field research consisted of two days of participant observation; four doodling workshops with a class of children - aged eight to 12 years old - and their educator; and a conversation circle with educators. The emphasis is, in this text, on the experiences of the second workshop and excerpts of the conversation circle, exploring the ability to create and play with words. With this, it was possible to highlight the importance of creative and spontaneous playing in human relations. The conclusion is that playing is not restricted to childhood, as it is an experience specific to humans, and that school and community spaces must be open to its manifestation and expansion. (AU)

Solar UV Measured under Built-Shade in Public Parks: Findings from a Randomized Trial in Denver and Melbourne.

Reducing exposure to ultraviolet radiation (UV) is crucial for preventing UV-induced diseases of the skin and eyes. Shade may offer significant protection from UV. More empirical research to quantify the UV protection offered from built shade is needed to guide disease prevention practices and confidence in investment in shade. This study quantified UV levels under built-shade relative to unshaded passive recreation areas (PRAs) over summer months in parks in two cities. In a randomized controlled trial, n = 1144 UV measurements were conducted at the center and periphery of PRAs in a total sample of 144 public parks as part of pretest and posttest measures of use of the PRAs by park visitors for three recruitment waves per city during 2010 to 2014. Following pretest, 36 PRAs received built-shade and 108 did not. Regression analyses modelled pre-post change in UV (Standard Erythemal Dose (SED) per 30 min) at PRAs; and environmental predictors. Mean UV at the center of built-shade PRAs decreased from pretest to posttest (x¯ = 3.39, x¯ = 0.93 SED), a change of x¯ = -3.47 SED relative to control PRAs (p < 0.001) adjusting for the covariates of ambient SED, (cosine) solar elevation and cloud cover. Clouds decreased and solar elevation increased UV levels under shade. No significant differences in UV by shade design occurred. A substantial reduction in exposure to UV can be achieved using built-shade with shade cloth designs, offering considerable protection for shade users. Supplementary sun protection is recommended for extended periods of shade use during clear sky days.

Playing With a Purpose: The Impact of Therapeutic Recreation During Hospitalization.

Background: Youth undergoing cancer treatment and hematopoietic stem cell transplant (HSCT) spend significant time in the hospital, which is disruptive to their physical, social, and emotional development. Therapeutic recreation (TR) can help individuals with an illness maintain or improve their health, quality of life, and physical functioning. TR is an understudied intervention, particularly with youth in the hospital setting. Methods: Forty-nine children (median age = 12 years, interquartile range [IQR] 11-15 years) hospitalized for cancer treatment or HSCT were assigned to participate in either the historical control or TR intervention. Participants wore a Fitbit charge HR for three days to measure movement. At the end of the study participation, they completed self-report measures of mood, social connectedness, and health-related quality of life. Results: Compared with historical controls, the TR intervention group had improved positive affect and decreased mood disturbance (p = 0.03); had better sleep quality (p = 0.003); and was more satisfied with the leisure activities offered in the hospital (p = 0.01). There were no differences in the number of steps taken per day, somatic distress, cooperation with cares, or interaction with medical personnel or caregivers. Both groups reported poor availability and support of peer companions. Discussion: TR is one avenue to increase leisure activities and positively impact mood. More thought needs to be given to how TR programs can be leveraged to increase physical activity and social connectedness.

The Association of Physical Activity and Urinary Incontinence in US Women: Results from a Multi-Year National Survey.

OBJECTIVES: To evaluate the relationships between physical activity, both work and recreational, and urinary incontinence among women. METHODS: We assessed women aged 20 years and older in 2008-2018 NHANES (National Health and Nutrition Examination Survey) cycles who answered self-reported urinary incontinence and physical activity questions. Weighted, multivariate logistic regression model was used to determine the association between incontinence and physical activity levels after adjusting for age, body mass index, diabetes, race, parity, menopause and smoking. RESULTS: A total of 30,213 women were included in analysis, of whom 23.15% had stress incontinence, 23.16% had urge incontinence, and 8.42% had mixed incontinence (answered "yes" to both stress and urge incontinence). Women who engaged in moderate recreational activity were less likely to report stress and urge incontinence (OR 0.79, 95% CI 0.62-0.99 and OR 0.66, 95% CI 0.48-0.90, respectively). Similarly, women who engaged in moderate activity work were less likely to report stress, urge and mixed incontinence (OR 0.84, 95% CI 0.70-0.99; OR 0.84, 95% CI 0.72-0.99; and OR 0.66 95% CI 0.45-0.97, respectively). CONCLUSIONS: Moderate physical activity and greater time spent participating in moderate physical activity are associated with a decreased likelihood of stress, urge and mixed incontinence in women. This relationship holds for both recreational and work-related activity. We hypothesize that the mechanism of this relationship is multifactorial, with moderate physical activity improving pelvic floor strength and modifying neurophysiological mediators (such as stress) involved in the pathogenesis of incontinence.

Radiopaque Recreations of Lung Pathologies From Clinical Computed Tomography Images Using Potassium Iodide Inkjet 3-dimensional Printing: Proof of Concept.

PURPOSE: The purpose of this study was to develop a 3-dimensional (3D) printing method to create computed tomography (CT) realistic phantoms of lung cancer nodules and lung parenchymal disease from clinical CT images. MATERIALS AND METHODS: Low-density paper was used as substrate material for inkjet printing with potassium iodide solution to reproduce phantoms that mimic the CT attenuation of lung parenchyma. The relationship between grayscale values and the corresponding CT numbers of prints was first established through the derivation of exponential fitted equation from scanning data. Next, chest CTs from patients with early-stage lung cancer and coronavirus disease 2019 (COVID-19) pneumonia were chosen for 3D printing. CT images of original lung nodule and the 3D-printed nodule phantom were compared based on pixel-to-pixel correlation and radiomic features. RESULTS: CT images of part-solid lung cancer and 3D-printed nodule phantom showed both high visual similarity and quantitative correlation. R2 values from linear regressions of pixel-to-pixel correlations between 5 sets of patient and 3D-printed image pairs were 0.92, 0.94, 0.86, 0.85, and 0.83, respectively. Comparison of radiomic measures between clinical CT and printed models demonstrated 6.1% median difference, with 25th and 75th percentile range at 2.4% and 15.2% absolute difference, respectively. The densities and parenchymal morphologies from COVID-19 pneumonia CT images were well reproduced in the 3D-printed phantom scans. CONCLUSION: The 3D printing method presented in this work facilitates creation of CT-realistic reproductions of lung cancer and parenchymal disease from individual patient scans with microbiological and pathology confirmation.

Recreational Physical Activity, Sitting, and Androgen Metabolism among Postmenopausal Women in the Women's Health Initiative Observational Study.

BACKGROUND: Prolonged sitting and physical inactivity are associated with higher circulating levels of estrogens. It is unknown whether these risk factors are associated with circulating androgens/androgen metabolites, another set of hormones implicated in the etiology of cancers in postmenopausal women. METHODS: We conducted a cross-sectional analysis of 1,782 postmenopausal women in the Women's Health Initiative Observational Study. Serum concentrations of 12 androgens/androgen metabolites were quantified using liquid chromatography-tandem mass spectrometry. Physical activity and sitting time were self-reported at baseline. We performed linear regression to estimate geometric means (GM) of androgen/androgen metabolite concentrations (pmol/L) according to physical activity and sitting time, adjusting for potential confounders and stratified by menopausal hormone therapy (MHT) use. RESULTS: Physical activity (≥15 vs. 0 MET-h/wk) was inversely associated with estrogen-to-androgen ratios among never/former MHT users (adj-GM = 37.5 vs. 49.6 unconjugated estrone:androstenedione; 20.2 vs. 30.3 unconjugated estradiol:testosterone; all P trend ≤ 0.03) but was not associated among current MHT users. Prolonged sitting (≥10 vs. ≤5 h/d) was positively associated with these ratios among both never/former (adj-GM = 44.2 vs. 38.3, P trend = 0.10; adj-GM = 23.4 vs. 20.2, P trend = 0.17; respectively) and current MHT users (adj-GM = 197 vs. 147; 105 vs. 75.5; respectively; all P trend ≤0.02), but the associations were statistically significant among current MHT users only. The associations persisted after adjustment for BMI. After adjustment for adrenal androgens, physical activity and sitting were not associated with androgen metabolites. CONCLUSIONS: Physical activity and sitting were associated with serum estrogen-to-androgen ratios but not androgen metabolites. IMPACT: This study contributes to our understanding of the link between physical activity, sitting, and cancer risk in postmenopausal women.
