Causas e conseqüências físicas e emocionais do término de carreira esportiva

Abstract: INTRODUCAO: Os atletas de alto rendimento, em determinado momento, se defrontam com o termino de carreira esportiva, um processo crucial e inevitavel, com exigencias de ajustamentos nas esferas da vida ocupacional, financeira, social e psicologica e, que, portanto, pode ser acompanhado por distress emocional. OBJETIVO: O presente estudo teve como objetivo pesquisar como ex-atletas brasileiros de alto nivel de basquetebol e futebol profissional experienciaram a aposentadoria da carreira esportiva, suas causas e consequencias fisicas e emocionais. METODOS: Para tanto, foram avaliados 79 ex-atletas de alto nivel, do sexo masculino, que pertenciam a duas modalidades esportivas: futebol (N = 57) e basquetebol (N = 22), com media de idade de 51,75 ± 8,85 anos. O tempo de pratica como atleta profissional foi de 18,22 ± 4,66 anos e o termino da carreira esportiva ocorreu em media aos 34,36 ± 4,42 anos. Utilizou-se uma entrevista semi-estruturada; os dados foram analisados pela frequencia de ocorrencia de respostas para cada item da entrevista. RESULTADOS: Observou-se que, para 75,9% dos atletas, a decisao de encerrar a carreira foi espontânea. A idade (49,4%) e outros interesses emergentes (43,0%) foram as principais causas da aposentadoria. Os sentimentos vivenciados nesse momento foram de tristeza (50,6%) e de conformismo (36,7%). Para 43% dos ex-atletas a condicao fisica piorou apos o termino da carreira. CONCLUSOES: Os autores concluem que, apesar de os atletas terem experienciado uma carreira esportiva longa, o momento de se aposentar no esporte trouxe sentimentos de tristeza. Por outro lado, a idade e um limitador para a carreira esportiva e reconhecer isso levou ao conformismo.

Conteúdos atitudinais nas aulas de Educação Física: um estudo de caso

Abstract: O objetivo do presente estudo foi identificar os conteudos atitudinais presentes nas aulas de Educacao Fisica e verificar como o professor atua para tornar possivel essa aprendizagem. Foi realizado um estudo de caso, com a aplicacao de entrevista estruturada e observacoes de 40 aulas de um professor de Educacao Fisica. Foram identificados varios conteudos da dimensao atitudinal presente nas aulas, como valores da pratica adequada da atividade fisica; atitudes como se divertir na pratica da atividades fisica; e normas como usar roupa adequada para a pratica da atividade fisica. Em sua intervencao, o professor se utiliza da identificacao e, em alguns momentos, de submissao. A interiorizacao de valores, atitudes e normas nao esteve presente nas observacoes realizadas, nem apareceu nos relatos do professor, durante a entrevista. Alem disso, foi possivel identificar que, em algumas situacoes, o conteudo atitudinal aparece sem que haja a intencionalidade do professor, ou seja, de maneira oculta. A partir desse estudo, confirma-se a presenca de conteudos da dimensao atitudinal nas aulas de educacao fisica, sendo que esses conteudos apareceram de forma mais rica, detalhada e especifica que em estudos anteriormente realizados. Dai a necessidade de que mais estudos focalizem a intervencao do professor.

O futebol e seu significado

Abstract: The aim of this study was to evaluate the soccer personal meaning For those, 194 soccer players from five teams, from the sub 13 to professional, were evaluated through an open question: “write down the soccer personal meaning” The meanings were categorized and interpreted, following common and different aspects for those Five categories arise: satisfaction, lifestyle, competence, relationship, and enjoyment For the professional soccer mean satisfaction and a lifestyle For the sub 13, a competence, and for the sub 15, an enjoyment and a relationship For the sub 17 and sub 20 there was a decreased in all categories We can conclude that at the beginning soccer players consider they were competent and soccer means enjoyment As they grow on the career, soccer becomes a passion, but also a lifestyle as we can see at the professional category

Poly (butylene succinate) and derivative copolymer filled with Dendranthema grandiflora biolarvicide extract

Abstract: Dengue is the most important infectious disease in the world and is a severe public health problem. The chikungunya is an arbovirus, in many cases, increased, which is transmitted by the same transmitter dengue vector, Aedes aegypti. The symptoms of both diseases are similar, and infections can be lethal. Although there is no preventive vaccine against any of the two diseases, therefore, it is extremely important to control the mosquito. The eggs of A. aegypti are very resistant and hatch into larvae, which later give rise to mosquitoes in any container with water. Natural plant extracts have come from active substances with larvicidal activity against A. aegypti. However, they tend to be highly hydrophobic and need some strategy to improve its affinity for water. Because of these factors, this research aims to synthesize and characterize polymeric materials with properties suitable for the release of hydrophobic principles with larvicidal action. The synthesized polymers are poly (butylene succinate) (PBS) and PBS block copolymer with polyethylene glycol (PEG). The synthesized polymers were characterized by nuclear magnetic resonance, thermal analysis simultaneous, differential scanning calorimetry, Fourier transform infrared spectroscopy, and diffraction of X-rays analysis. The analysis results showed that the synthesized materials have chemical composition and properties suitable for use in the controlled release of actives substances. Systems were prepared using the Dendranthema grandiflora extract, which has larvicidal activity was incorporated via fusion to polymers, to evaluate its release in aqueous media. The results proved that higher amounts of PEG in the copolymer chain speed up the delivery of the larvicidal extract. Besides that, the larvicidal extract concentration required to cause death larvae of A. aegypti was achieved from the first minutes of dissolution tests, indicating that the materials developed are promising tool to fight dengue and chikungunya. This new system is a vital tool for eliminating vectors, potentially contributing to saving millions of lives worldwide.

Familial history of hypertension-induced impairment on heart rate variability was not observed in strength-trained subjects

Abstract: Family history of hypertension is an important predictive factor for hypertension and is associated with hemodynamic and autonomic abnormalities. Previous studies reported that strength training might reduce arterial blood pressure (AP), as well as improve heart rate variability (HRV). However, the benefits of strength training in the offspring of hypertensive parents have not been fully evaluated. Here, we analyzed the impact of strength training on hemodynamics and autonomic parameters in offspring of hypertensive subjects. We performed a cross-sectional study with sedentary or physically active offspring of normotensives (S-ON and A-ON) or hypertensives (S-OH and A-OH). We recorded RR interval for analysis of HRV. AP was similar between groups. Sedentary offspring of hypertensives presented impairment of total variance of RR interval, as well as an increase in cardiac sympathovagal balance (S-OH: 4.2±0.7 vs S-ON: 2.8±0.4 and A-ON: 2.4±0.1). In contrast, the strength-trained group with a family history of hypertension did not show such dysfunctions. In conclusion, sedentary offspring of hypertensives, despite displaying no changes in AP, showed reduced HRV, reinforcing the hypothesis that autonomic dysfunctions have been associated with higher risk of hypertension onset. Our findings demonstrated that strength-trained offspring of hypertensives did not present impaired HRV, thus reinforcing the benefits of an active lifestyle in the prevention of early dysfunctions associated with the onset of hypertension in predisposed populations.
