A InfluÃncia da Capoeira no Desenvolvimento Psicomotor de CrianÃas / The influence of capoeira in the development of children psychomotor

Andreyson Calixto de Brito 18 August 2014 (has links)
FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico / O desenvolvimento psicomotor à caracterizado por um processo progressivo e continuo onde se dà a evoluÃÃo da cogniÃÃo, da afetividade, da motricidade, da comunicaÃÃo e da sociabilidade, de forma global, simultÃnea e integrada. O estudo teve como objetivo avaliar os efeitos da prÃtica da capoeira no desenvolvimento psicomotor na infÃncia. A amostra foi constituÃda por 54 alunos do segundo ano do ensino fundamental da rede municipal de ensino de Fortaleza, com idades de 6 a 12 anos, divididos em dois grupos: grupo experimental (14 do sexo masculino - 15 do sexo feminino) e grupo de controle (12 sexo masculino â 13 sexo feminino). As crianÃas do grupo experimental foram submetidas à prÃtica da capoeira duas vezes por semana, durante 32 semanas, com 45 minutos cada sessÃo, enquanto o grupo de controle nÃo participou das aulas de capoeira. A BPM (Bateria Psicomotora) foi utilizada para avaliar o desenvolvimento psicomotor. A ferramenta estatÃstica utilizada foi o Statistical Package for the Social Sciences (SPSS), versÃo 20.0. O nÃvel de significÃncia foi estabelecido em p &#8804; 0,05. As principais conclusÃes deste estudo relativamente ao desenvolvimento psicomotor das crianÃas foram as seguintes: a) o sexo feminino obteve melhores resultados em quase todos os testes aplicados, no prÃ-teste e no pÃs-teste, com diferenÃas estatisticamente significativas para praxia fina, no grupo experimental, durante prÃ-teste, e para noÃÃo de corpo, nos dois grupos, no pÃs-teste; b) no pÃs teste, o grupo experimental apresentou melhor desempenho em ambos os sexos nos sete fatores avaliados; c) o grupo experimental demonstrou melhorias no desempenho, do primeiro para o segundo momento de avaliaÃÃo, com diferenÃas estatisticamente significativas em todos os testes aplicados para avaliaÃÃo do desenvolvimento psicomotor: tonicidade (p < 0,01); equilibraÃÃo (p < 0,00); lateralizaÃÃo (p < 0,00); noÃÃo de corpo (p < 0,00); estruturaÃÃo espaciotemporal (p < 0,00); praxia global (p < 0,00) e praxia fina (p < 0,00). Este exprimento sugere que a prÃtica da capoeira pode contribuir para potencializar o desenvolvimento psicomotor em crianÃas. / Psychomotor development is characterized by a progressive and continuous process which takes the evolution of cognition, affectivity, motor skills, communication and sociability, as a whole, simultaneous and integrated. The study aimed to evaluate the effects of the practice of capoeira psychomotor development in infancy. The sample consisted of 54 students of the second year of the municipal elementary education schools in Fortaleza, aged 6-12 years divided into two groups: experimental group (14 male - 15 female) and group control (12 male - 13 female). Children in the experimental group were subjected to the practice of capoeira twice a week for 32 weeks, with 45 minutes each session, while the control group did not participate in capoeira classes. The BPM (Psychomotor Battery) was used to assess psychomotor development. The statistical tool used was the Statistical Package for Social Sciences (SPSS) version 20.0. The level of significance was set at p &#8804; 0.05. The main conclusions of this study regarding the psychomotor development of the children were as follows: a) females had better results in almost all tests, the pre-test and post-test, with statistically significant differences for thin praxis, the group trial during pre-test, and the notion of the body, in both groups at post-test; b) the post-test, the experimental group performed better in both sexes in the seven factors evaluated; c) the experimental group showed improvements in performance from the first to the second assessment, with statistically significant differences in all tests for evaluation of psychomotor development: tone (p <0.01); equilibration (p <0.00); lateralization (p <0.00); notion of the body (p <0.00); spatiotemporal structure (p <0.00); global praxis (p <0.00) and thin praxis (p <0.00). From the results obtained in this study, we conclude that the practice of capoeira, when well targeted, delivers significant improvements in psychomotor development of children.

Participaram do estudo 40 crianças de uma escola pública da rede Municipal da cidade de Vinhedo. Como se tratava de quatro turmas de fase II na unidade escolar foram selecionadas 10 crianças de cada sala, sendo cinco meninos e cinco meninas. O diagnóstico foi realizado individualmente por meio de uma avaliação psicomotora, que verifica as habilidades no que se refere à coordenação e equilíbrio, esquema corporal, lateralidade, organização e estruturação espacial e organização e estruturação temporal. Os dados referentes à avaliação psicomotora (Oliveira, 2010b) foram analisados e comparados a partir dos fundamentos teóricos da Psicomotricidade, tendo como referência o nível de desenvolvimento psicomotor compatível com a faixa-etária avaliada. A análise dos dados se deu de forma qualitativa (descrição e discussão do desenvolvimento psicomotor apresentado pelos alunos da escola analisada); descritiva (análise das principais variáveis do banco de dados total); comparativa (discussão das variáveis entre os gêneros através dos testes qui-quadrado de Pearson e exato de Fisher) e gráfica (apresentação dos principais dados encontrados). Os resultados encontrados revelam que um número elevado de crianças apresentou dificuldade nas provas de Lateralidade e Orientação Temporal. Ao comparar os gêneros, o estudo constatou não haver diferença significativa entre os meninos e as meninas para nenhuma das variáveis avaliadas, apenas uma leve tendência de um melhor desempenho das meninas para Orientação Espacial e Orientação Temporal. / Abstract: The objective of this research was to verify the motor age of children, by means of diagnosis of psychomotor skills, in the last three months of child education. Study participants were 40 children in a public school of the city of Vinhedo. As it was fou classes of phase II in school unit were selected 10 children in each room, five boys and five girls. The diagnosis was made individually by means of a psychomotor evaluation, which checks the abilities with regard to the coordination and balance, body scheme, laterality, space organization and structure and time organization and structuring. The data relating to the psychomotor evaluation (Oliveira, 2010b) were analyzed and compared from the theoretical foundations of Psychomotricity, in relation to the level of psychomotor development compatible with the age group assessed. The data analysis was done in a qualitative way (description and discussion of psychomotor development presented by the students of examined school); descriptive (analysis of the main variables of the total database); Comparative (discussion of variables between genders by Person's qui-quadrado test and Fisher's exato) and graphic (presentation of the main data found). The results show that a large number of children had a lot of difficulty in laterality and Temporal Orientation evidence. When compare the genus the study found no significant difference between the boys and girls for any of the variables assessed, only a slight tendency for a better performance of the girls for spatial orientation and Temporal Orientation. / Mestrado / Psicologia Educacional / Mestre em Educação

Intestinal Parasitic Infection: Prevalence, Risk Factors and Consequences for Child Growth, Iron Status and Development in Rural Ecuador

Sackey, Mamie Eleanor 24 August 2001 (has links)
Intestinal parasitic infections (IPI's) are considered to be a public health problem of global importance by the World Health Organization. The present epidemiologic survey study investigated the prevalence, risk factors, and consequences of pathogenic IPI's on the growth, nutrition and psychomotor development of 244 Ecuadorian children aged 0.2-14 years. The study was conducted in five rural hamlets located in a tropical rainforest area in northwest Ecuador. The study data were obtained by means of a structured questionnaire, a developmental screening examination, anthropometry, and lab analysis of blood and fecal samples. Data analysis was conducted using appropriate bivariate and multivariate statistical techniques. The study results revealed that 90% of the child subjects were infected with at least one pathogenic IPI species. Fifty-one percent were identified with helminthic infections, 37.6% with protozoal infections, and 21.4% were infected with both. The most common intestinal parasites detected were Ascaris lumbricoides (39.7%), Giardia intestinalis (25.2%), Trichuris trichiura (19.7%), Entamoeba histolytica/dispar (18.5%), Blastocystis hominis (13.3%), and Ancylostoma duodenale (1.7%). The prevalence of growth stunting (40%) and iron-deficiency anemia (26%) also was high. Children infected with Giardia exhibited a risk for stunted growth that was twice that of their non-infected counterparts (51.7% vs. 33.1%; OR=2.16, 95% C.I.= 1.13-4.15; p= 0.01). They also had significantly reduced mean blood hemoglobin levels compared to non-infected children 11.8 + 1.5.g/dL vs. 12.2 + 1.4g/dL; p= 0.023) but the proportion with iron-deficiency anemia was slightly but not significantly increased (29.4% vs. 24.3%). The characteristic most consistently associated with risk for pathogenic protozoal IPI's was a high density of domestic animals living in and around the home. Children who lived in such households had a risk for infection that was 2-5 times greater than others. This suggests that domestic animals were important reservoirs for IPI infection in the child group studied. Contrary to the a priori hypothesis, no gender, ethnic, nor age differences in infection risk were identified except for Trichuris infection, which was reduced in younger children contrary to expectations. Mass or targeted chemotherapy combined with health education and promotion are needed to reduce the cycle of infection and re-infection and the negative impact of these on child growth and iron status. Health education and promotion messages can be incorporated into other types of programs already in place in local schools and by the Ecuadorian Ministries of Public Health, Education, and Social Welfare and other agencies. / Master of Science

Department: Department of Rehabilitation and Exercise Medicine Supervisor: doc. PharmDr. H. Kubová, DrSc. The year of presentation: 2013 Abstract: The purpose of this study is to evaluate the influence of status epilepticus (SE) in postnatal development early phase on laboratory rat psychomotor development. Experimentally caused (SE) is the most common mode of epileptogenesis, which is the process leading to the epilepsy creation, and typical comorbidities. The influence of the early SE was studied when using lithium/pilocarpine model of SE induced on 12 days old rat cubs, which were repeatedly exposed to the "open field" test until 32nd day of their lives that means until the puberty beginning. The evaluation is focused on cognition and overall locomotion changes and anxiety demonstrations. The results show that in short periods after SE (up to 1 month) the cognitive functions regarding the habituation disorder are not worsened. However, hyperactivity short-term disposition and worse adaptability to experimental conditions due to animal anxiety increase were detected. Motor skills of...

Association of Neonatal Thyroid Stimulating Hormone Concentration with Intellectual, Psychomotor and Psychosocial Development of Preschool Children

Trumpff, Caroline 11 December 2015 (has links)
Iodine is necessary for thyroid hormones synthesis which in turn are essential for brain development during fetal and early postnatal life. In these critical periods, severe iodine deficiency can induce irreversible brain damage in the fetus and the infant, resulting in retarded cognitive and/or psychomotor development. Despite the introduction of salt iodization programs such as national measures to control iodine deficiency, some European countries, including Belgium, are still affected by Mild Iodine Deficiency (MID) and MID during pregnancy may affect neurodevelopment of the offspring. Elevated thyroid stimulating hormone (TSH) concentration (>5mU/l) at birth has been used as an indicator of iodine deficiency during late pregnancy and at the population level. This doctoral research aimed to investigate the association between neonatal TSH level, used as a surrogate marker of MID during late pregnancy, and cognitive, psychomotor and psychosocial development of preschool children. It was hypothesized that elevation of TSH at birth is associated with impaired intellectual and psychomotor development and with behavioral problems at 4-5 years. As the use of TSH as an indicator of iodine deficiency has been criticized, we have also set out to assess the potential factors influencing neonatal TSH level measured through neonatal screening using a representative sample of TSH values between 0 and 15 mIU/L. Additionally, we aimed to reevaluate the neonatal TSH cut-off (5mIU/L) used to monitor iodine status in the population. The objective was to evaluate the cut-off point from which we can observe the impairment of children’s neurodevelopment. We hypothesized that this is a good way to establish the best cut-off value for identifying iodine deficiency.The study included 315 Belgian preschool children with a TSH concentration between 0 and 15 mU/L at screening. For each sex and TSH-interval (0-1 mU/L, 1-2 mU/L, 2-3 mU/L, 3-4 mU/L, 4-5 mU/L, 5-6 mU/L, 6-7 mU/L, 7-8 mU/L, 8-9 mU/L, 9-15 mU/L) 19 newborns were randomly selected after excluding infants with congenital hypothyroidism, low birth weight and premature infants. Neonatal TSH was measured in dried blood spots collected by heel stick 3 to 5 days after birth using the Autodelphia method. Cognitive abilities and psychomotor development were assessed using respectively the Wechsler Preschool and Primary Scale of Intelligence-III and the Charlop-Atwell scale of motor coordination. Psychosocial development was measured using the Child Behavior Check List for ages 1½-5 years. In addition, the mothers completed a self-administered questionnaire in order to account for confounding factors. No association between neonatal TSH within the range of 0 to 15 mIU/L - a surrogate marker for mild iodine deficiency during pregnancy and neurocognitive development was present in Belgian preschool children. The current level of iodine deficiency in Belgium is probably not severe enough to affect the neurodevelopment of children. In this study, we were able to identify several maternal and pregnancy related determinants of neonatal TSH levels. Higher TSH levels were associated with a lifetime (up to child birth) smoking behavior in the mother, a lower weight gain during pregnancy, a longer pregnancy duration. Higher TSH levels were found in spring and winter compared to summer and autumn. It is not advised to use elevated neonatal TSH levels at birth as an indicator of iodine deficiency during late pregnancy without taking potential covariates into account. Given the fact that no association was found between TSH and developmental scores in the children, we cannot evaluate the cut-off point from which we can observe the impairment of children’s neurodevelopment. / Doctorat en Sciences psychologiques et de l'éducation / info:eu-repo/semantics/nonPublished
