Correlação fenotípica das características peso, perímetro torácico e altura ao garrote em cavalos Puro-sangue Lusitano
Get PDFComunicação em painelO objetivo deste estudo foi avaliar a existência de correlações entre as características fenotípicas: peso vivo obtido em balança digital de equinos (BD), perímetro torácico (PT) e altura ao garrote (AG) de cavalos Puro-Sangue Lusitano (PSL). Dado ser comum a utilização destas medidas (PT e AG) para estimar um peso aproximado, por intermédio de várias fórmulas de cálculo. Para o efeito foram avaliados 41 cavalos de raça PSL (todos machos inteiros), com idades entre os 3 e os 21 anos. Os animais foram pesados numa BD (erro 0,5 kg), a AG (cm) foi medida com hipómetro e o PT (cm) com fita métrica (FM). Os dados apresentaram uma distribuição não paramétrica, tendo sido calculados os coeficientes de correlação de Spearman. Os resultados indicaram uma correlação elevada entre o peso obtido por BD e a medida PT (r=0,916; p<0,05), sendo reduzido o intervalo de confiança bilateral a 95% (IC95%) com 0,829 a 0,960, indicando claramente que uma variação no peso ou medida PT vai fazer variar o valor do outro. Foi observada uma correlação moderada do peso BD com a AG (r=0,467; p<0,05) e elevado IC95% (0,170 a 0,687), sugerindo que o facto de o cavalo aumentar o peso ou altura, nem sempre vai alterar o outro valor. Relação semelhante, foi observada entre as medidas PT e AG (r=0,459; p<0,05) com elevado IC95% (0,160 a 0,680). Os resultados sugerem que o peso vivo dos cavalos PSL avaliados está fortemente correlacionado com o PT e que existe uma elevada variação com a AG. O estudo sugere que a utilização de fórmulas de cálculo para obter um peso aproximado em machos da raça PSL, deve ser desenvolvida por intermédio da medida perímetro torácico.info:eu-repo/semantics/publishedVersio
The contribution of the artistic workshops measured by the Rosenberg Self-Esteem Scale
Get PDFMental health is now considered indispensable for well-being and general health. Self-esteem, in turn, is an important indicator of mental health. Knowing the self-esteem of people with Mental Illness thus becomes an important part of the process of help and recovery, promoting the implementation of appropriate therapeutic measures. This study aims to determine the impact of the INcluir workshops on participants’ self-esteem,
an experimental study composed of adult participants of both genders. Two groups were created: the control group composed of participants who did not attend the artistic workshops and the experimental group who attended the workshops. The Rosenberg Self-Esteem Scale (RSES) was used to measure the levels of self-esteem. Considering the results obtained, the artistic workshops produced improvements in the participants’ self-esteem.info:eu-repo/semantics/publishedVersio
The effects of whole-body muscle stimulation on body composition and strength parameters: a PRISMA systematic review and meta-analysis
Get PDFBackground: This systematic review and meta-analysis set out to determine the efficacy of whole-body muscle electrostimulation on body composition, strength, and muscle power in active and non-active adults (aged ≥18 years). Method: This review was reported in accordance with the Protocol Statement of Preferred Reporting Element Guidelines for Systematic Reviews and Meta-Analysis included controlled trials; whole-body electromyostimulation trials with at least 1 exercise and control group; participants >18 years old. Outcome measures were defined as standardized mean differences for muscle mass, body fat mass, strength, and power. Studies were searched in the following electronic databases: PubMed, Web of Science, Scopus, SPORTDiscus, and EMBASE for all articles published up to July 30, 2021. The risk of bias was assessed by 2 independent researchers using the Physiotherapy Evidence Database scale and Grading of Recommendations, Assessment, Development and Evaluations approach. Analyses were performed using the metafor package of the statistical software R (version 4.0.3; R Core Team, 2020). Random effects models, forest, and funnel plots to quantify the asymmetry associated with publication bias were fitted using the metafor library in R. Statistical heterogeneity was assessed using I 2 statistics. Results: In total, 26 studies representing 1183 participants were included (WB-electromyostimulation: n = 586 and control group: n = 597). The mean age of the participants ranged from a minimum of 20.4 to a maximum of 77.4 years old. Interventions lasted a minimum of 4 and a maximum of 54 weeks. Standardized mean difference was 0.36 (95% confidence interval [CI]: 0.16–0.57) for muscle mass, −0.38 (95% CI: −0.62–0.15) for body fat, 0.54 (95% CI: 0.35–0.72) for strength, and 0.36 (95% CI: 0.02–0.71) for power with significant differences between groups (all P < .04). I 2 revealed low heterogeneity of muscle mass (15%) and power (0%) between trials and medium heterogeneity of body fat (45%) and strength (55%). Conclusion: We concluded that WB-electromyostimulation has significant positive effects on muscle mass, body fat, strength, and power.info:eu-repo/semantics/publishedVersio

Learning to cycle in 5 hours? results of 2 interventions
No full textCapacitar as nossas crianças a ciclar é capacitá-las para uma vida mais saudável, mais plena e mais responsável. A utilização da bicicleta com rodas laterais de treino (BRL) é a abordagem mais comum para aprender a ciclar, no entanto a literatura sugere-a como contraproducente. O presente estudo implementou o programa Learning to Cycle com os objetivos de: i) promover a aquisição de ciclar, e ii) investigar e comparar a utilização da bicicleta de equilíbrio (BE) e BRL durante esta aquisição. Participaram 51 crianças (M=5,82±0,94 anos) do pré-escolar e 1ºCEB, que não sabiam ciclar previamente, divididas por 2 grupos. Um grupo explorou a BE e outro a BRL durante 6 sessões, seguindo-se mais 4 sessões com a bicicleta convencional (BC). A avaliação do ciclar independente foi considerada como a capacidade de realizar, sequencialmente e sem ajuda, os seguintes marcos de ciclar: iniciar, equilibrar e travar. Foi registado o número de sessões com a BC que cada criança necessitou para adquirir cada marco de ciclar e o ciclar independente. O programa revelou 88,24% de sucesso para a aquisição de ciclar independente, 100% na BE e 76,92% na BRL. As crianças do grupo da BE adquiriram significativamente mais rápido os marcos de iniciar, equilibrar e travar, bem como o ciclar independente. Os resultados evidenciam que a intervenção para adquirir o ciclar pode ser aplicada com sucesso a partir do pré-escolar, e que a BE é uma bicicleta de aprendizagem mais eficiente que a BRL.Empowering children to cycle empowers them for a healthier, fuller, and more responsible life. Training wheels are commonly used to learn how to ride a bike, but literature suggests they are counterproductive. In this study, we implemented the Learning to Cycle program to: i) promoting cycling acquisition, and ii) investigating and comparing the use of balance bikes (BE) and training wheels (BRL) during this acquisition process. Fifty-one children (M=5.82±0.94 years) from preschool and primary school, who did not previously know how to cycle, participated in the study. Children were divided into 2 groups, one group explored the BE and the other the BRL during 6 sessions, followed by 4 more sessions with a conventional bicycle (BC). The number of sessions with CB that each child needed to acquire each cycle milestone and the independent cycling was recorded. Independent cycling assessment was considered as the ability to sequentially and unassisted perform the following cycle milestones: starting, balancing, and stopping. The BB’s acquired the starting, balancing and braking milestones, as well as independent cycling, significantly faster. The program had 88.24% success for independent cycle acquisition, 100% in BE and 76.92% in BRL. These findings suggest that cycle acquisition can be successfully introduced from preschool age, and balance bikes are more efficient for learning than training wheels.info:eu-repo/semantics/publishedVersio
Motricidade fina no teste de batidas do dedo com crianças: análise da entropia incremental
No full textDuring the development process, the nervous system is constantly changing (1). The application of non-linear measures such as entropy has allowed a deeper analysis of motor control (3). The Finger Tapping Test (FTT) is usually used to assess fine motor skills, and in this study we intend to use this test to analyze entropy levels and assess the development of fine motor control in children. Sixty children (M=8.141±1.064) participated in this study. Participants performed the FTT, 6 trials tapping with the index finger on a surface as fast as possible for ten seconds per trial. The test started with the preferred hand, followed by the non-preferred one. An inertial sensor was used to collect three-dimensional angular velocity. The entropy results indicated a change that occurs between the ages of 7 and 8 years old. It was observed that 6-years-old children, compared to other age groups, had lower entropy values, suggesting that they were more predictable when performing the FTT. The 8-years-old children seemed to have the highest entropy values, which might indicate that these children were less predictable (4). These findings suggest a transition to the third childhood, where significant changes occur in the nervous system during development. Entropy appears to be highly sensitive to these changes.Durante o processo de desenvolvimento, o sistema nervoso está em constante mudança (1). A aplicação de ferramentas não-lineares como, a entropia, tem permitido uma análise mais profunda do controlo motor (3). O Finger Tapping Test (FTT) ou teste de batidas do dedo é normalmente utilizado para avaliar a motricidade fina, e neste estudo pretende-se utilizar este teste para analisar os níveis de entropia e avaliar o desenvolvimento do controlo motor fino em crianças. Sessenta crianças (M=8,141±1,064) participaram deste estudo. Os participantes realizaram o FTT, 6 tentativas batendo com o dedo indicador em uma superfície o mais rápido possível por dez segundos por tentativa. O teste iniciava com a mão preferida, seguida da não preferida. Um sensor inercial foi utilizado para recolher os dados tridimensionais de velocidade angular. Os resultados da entropia indicaram uma alteração que ocorre entre os 7 e os 8 anos. Observou-se que as crianças de 6 anos, em comparação com outras faixas etárias, apresentaram valores de entropia mais baixos, sugerindo que eram mais previsíveis ao realizar o FTT. As crianças de 8 anos apresentaram maiores valores de entropia, o que pode significar que eram menos previsíveis (4). Estes resultados sugerem uma possível transição para a terceira infância, onde parecem ocorrer mudanças significativas no sistema nervoso durante o desenvolvimento. A entropia parece ser altamente sensível a essas mudanças.info:eu-repo/semantics/publishedVersio
Yogic slow paced abdominal breathing and heart rate variability in 7–8-years- old children
No full textA variabilidade da frequência cardíaca (VFC) é um indicador de saúde. Uma respiração lenta pode propiciar o seu aumento. Fomos verificar se crianças de 7 e 8 anos conseguiriam executar uma respiração predominantemente diafragmática, e qual o seu efeito agudo em parâmetros da VFC. Ocorreu uma redução significativa da frequência respiratória e um aumento da VFC. As crianças conseguiram executar esta técnica respiratória ióguica, com efeitos positivos agudos no seu sistema cardíaco.Heart rate variability (HRV) is an indicator of health. A slow breath can propitiate its increase. We went to see whether 7- and 8-year-old children could perform predominantly diaphragmatic breathing, and what is its acute effect on HRV parameters. There was a significant reduction in respiratory rate and an increase in HRV. The children were able to perform this yogic breathing technique, with acute positive effects on their cardiac system.info:eu-repo/semantics/publishedVersio
Perception and motor competence in self-controlled practice in performing the forward roll on the beam at different levels of motor difficulty by formation level practitioners
No full textA trave é um aparelho desportivo feminino, embora com origem gímnica masculina, que impõe constrangimentos físicos específicos. Fomos verificar se crianças praticantes de ginástica artística desportiva (N=35; 9,2±1,7 anos; experiência- 3,7±1,6 anos; 7 meninos) coincidiam na escolha e capacidade efetiva de realização do rolamento à frente na trave, perante diferentes níveis de dificuldade da tarefa. Os meninos revelaram uma perceção incorreta da sua capacidade de execução motora e não tiveram qualquer sucesso, mesmo no nível mais simples, que só tinha a limitação visual da largura da banda onde executava, o que implicaria maior linearidade na execução e utilização de menor base de apoio para mãos e pés; desconhecemos se a perceção da performance poderia decorrer da diferença entre géneros nos aparelhos da ginástica artística desportiva. Tanto meninas como meninos, seja qual for o escalão, têm uma perceção desajustada da sua real capacidade de prestação. Provavelmente, a aprendizagem autorregulada deve basear-se na exploração efetiva de diferentes níveis de dificuldade e não na perceção da competência motora pessoal.The beam is a female sports device, although with a male gymnastic origin, which imposes specific physical constraints. We went to verify whether children practicing sports artistic gymnastics (N=35; 9.2±1.7 years; experience- 3.7±1.6 years; 7 boys) coincided in the choice and effective ability to carry out the front roll on the beam, before different task difficulty levels. The boys revealed an incorrect perception of their motor execution capacity and did not have any success, even at the simplest level, which in relation to rolling forward on the ground only had the visual limitation of the width of the band where to perform it, but which would imply greater linearity in the execution and use of a smaller support base for hands and feet; it is not known whether it was for performative reasons, that is, due to the difference between genders in sports artistic gymnastics equipment. Both girls and boys, whatever the age group, have a misperception of their real performance capacity. Probably, self-regulated learning should be based on the effective exploration of different levels of difficulty and not on the perception of personal motor competence.info:eu-repo/semantics/publishedVersio
Conceptions of portuguese prospective teachers about real-life evolution situations
Get PDFThe importance of introducing evolution in primary schools has been highlighted in evolution education research, but few studies have approached the understanding of evolution of prospective teachers who are being prepared to teach at primary school level. The present exploratory study aims to answer three research questions about the ability of Portuguese prospective teachers to apply evolution to two real-life situations: 1) Are prospective teachers able to identify evolution misconceptions in online newspaper articles? 2) What misconceptions are expressed by prospective teachers when explaining real-life evolution situations? and 3) Which key evolution concepts do prospective teachers apply to make sense of real-life evolution situations? Twelve prospective teachers participated in the study. In the first situation, the prospective teachers were asked to identify statements from a newspaper article that would reveal evolution misconceptions and justify their choices. In the second situation, they were asked to read a text about SARS-CoV-2 and explain why scientists were worried about uncontrolled outbreaks of the virus. The prospective teachers’ answers were analysed through content analysis. Regarding the first research question, our results show that only half of the prospective teachers were able to identify teleological misconceptions in the newspaper article. Concerning the second research question, some of the prospective teachers either identified misconceptions in information in which there was no misconception, or revealed their own misconceptions in their explanations. Regarding the third research question, although more than half of the prospective teachers identified at least two key evolution concepts, some of them found it difficult to explain how evolution is related to the situation described. Although this is an exploratory study, it shows which key concepts of evolution the prospective teachers mobilised and identifies their misunderstandings, thus highlighting dimensions that should be addressed in their evolution education.info:eu-repo/semantics/publishedVersio
As intervenções do enfermeiro especialista em saude materna e obstetrica na promoção da sexualidade satisfatória no pos-parto.
Get PDFDissertação apresentada para obtenção do grau de Mestre em Enfermagem de Saúde Materna e ObstetríciaA gravidez é um processo altamente desafiador para o casal, sujeito a diversos processos de transição individuais, e em particular na sexualidade dos mesmos. A intervenção do Enfermeiro-Especialista-em-Enfermagem-de-Saúde-Materna-e-Obstétrica deve acompanhar os indivíduos em todas as fases do pré ao pós-parto, empoderando a mulher/casal na tomada de decisão sobre a sua saúde, promovendo uma sexualidade satisfatória ao longo da gravidez e em particular no pós-parto. Foi desenvolvida uma scoping review com o objetivo de mapear a evidência disponível sobre das intervenções do Enfermeiro Especialista em Enfermagem de Saúde Materna e Obstétrica, promotoras de uma sexualidade satisfatória no pós-parto, tendo se obtido três artigos para análise. Os resultados mostram-nos que os profissionais de saúde reconhecem que a sexualidade continua a ser menosprezada na prática por falta de conhecimento e à vontade para abordar o tema junto dos casais, sendo um tema que deve ser incluído nas consultas. Neste relatório, a análise dos cuidados de enfermagem foi feita à luz da Teoria das Transições desenvolvido por Afaf Meleis. Procedeu-se a uma análise crítica das atividades desenvolvidas ao longo do estágio realizado num bloco de partos.Pregnancy is a highly challenging process for the couple, subject to various individual and joint transition processes, particularly in terms of their sexuality. The intervention of the Maternal and Obstetric Health Nurse Specialist should accompany individuals at all stages of the pre- and post-partum period, empowering women/couples to make decisions about their health, promoting satisfactory sexuality throughout pregnancy and particularly in the post-partum period. Therefore, a scoping review was carried out with the aim of mapping the available evidence on interventions by Maternal and Obstetric Health Nurse Specialists to promote satisfactory sexuality in the postpartum period. The results show us that the healthcare professionals recognize that the sexuality continues to be undervalue in the practice, aknowledging the lack of information and ease to approach this theme with the couples, although this should be included in the appointment. This report analyses nursing care in the light of the Transitions Theory developed by Afaf Meleis. A critical analysis was made of the activities carried out during the internship in the labour ward.N/
