Influência das aulas de educação física na prática de atividades esportivas iniciais

The sports activities occupy a growing space in people's lives, especially children and youth. Taking into consideration that this practice is of paramount importance, especially in childhood, where the acquired habits influence in adulthood, this work aims to investigate the role of physical education classes in adherence of children to the practice of some activity sports. These are a dynamic process, and to realize it is necessary planning, making the practice is a pleasurable activity. Thus, an important point to note is the motivation, which depends on extrinsic and intrinsic factors. Another factor that may interfere in the sporting practices is the influence of parents on children. In this context, the contact sports can be used to gain the approval of parents and not for self-gratification, this being a way to get closer to distant parents. A point worth mentioning is the physical education, as this introduces and integrates the child's body / movement culture. Often child's first contact with the sport happens at school, leading us to the assumption that the physical education teachers at the school are responsible for the athletic student motivation, and we emphasize that the school motivational factors are very dependent on students' aspirations for that a particular motivational element can take effect. The technical and / or professional outside of school physical education also influence the child, as these can provide pleasure for the sport, being a connoisseur of motivational strategies. An important motivational aspect is friendship, as children use sports activities to make new friends and find your friends. In addition, some extrinsic factors can influence the practice, such as: win, work out, play, socializing, competition, fun, etc. The drop can be caused by various reasons, such as early specialization, participation in very specific competitions for which the child is not yet ready. In addition, other factors can be...

Uso de substâncias ergogênicas suplementares nutricionais em praticantes de musculação

Ergogenic substances are all nutritional or pharmacological additional devices which physiologically influence on the individual's performance. Currently, the practice of physical exercises that modern gyms have is growing and embracing a new recreational space for the population. In particular, for the male audience, weight training; and for the female audience, aerobic gymnastics. This study has the objective of explaining the importance of ergogenic resources in the physiological and psychological planes, emphasizing the point that supplementation is really valid and beneficial. To achieve the objective of the study, a literature review will be carried out, searching for scientific articles published in books, magazines and online newspapers that address some issues that cut across the thematic proposed in this work. From the point of view of Sport Psychology, the issues discussed on body image and emotional changes have concerns professionals of this area, but the literature suggests it is unnecessary the use of ergogenic substances to the concreteness of that purpose. Supplements of any kind will not be enough to transform the psychological and physiological aspects, the way the media assume conclusively. Thus, with our documentary research, we started a provocation that feeds new studies in the area. We conclude that supplementation is a resource that should be used in the final occasion, that is, if the bodybuilders (non-athletes) have time to be nourished from the normal diet, the use of supplements like whey and creatine, are not needed. Used appropriately supplements do not result in physiological damage, however, can contribute beneficially to the individual's nutrition, thus the abusing dosages, in addition to financial loss, can cause damage to the body

A ingestão de carboidrato e sua influência na modalidade futebol. -

Soccer is characterized as a sport that has exercises such as jumping, high-intensity and easy running, directional changes among, and other things. These features characterize soccer as an intermittent exercise. Nutrition along with proper exercise programs can be an excellent tool for the success or failure of the team in a championship. The nutrition, when properly oriented, can decrease fatigue of athletes and also optimize their recovery level, which may result in maintenance of performance along with less risk of injury. This study researched in database Pubmed, Scielo and Bireme, using the following words: futebol, nutrição, carboidrato, carbohydrate, soccer, and nutrition. Carbohydrate is a macronutrient used as energy source for performing exercise and its prevalence is varied according to both volume and intensity of exercise. In soccer, there is recommendation for carbohydrate intake before exercise in order to increase the availability of blood glucose, which in turn results in exercise improved capacity. In addition, carbohydrate intake during exercise increases the rapid replacement of all muscle glycogen reserves lost. Finally, the post-exercise consumption is important in the recovery of several nutritional factors such as muscle glycogen restoration, replacement of fluids and also electrolytes. In this sense, a well-oriented carbohydrate intake will result in improved athlete performance, and than may also promotes the success of their team at the end of the championship

Influência da música preferida no desempenho e estados afetivos de idosos durante exercício de intensidade auto-selecionada

Low adherence to physical exercise programs is a factor that contributes to the high rates of physical inactivity worldwide. In this sense, strategies to improve the affective responses during exercise are used to impact adherence, as the use of music and self-selected exercise intensity. Despite the benefits of these strategies, there are few studies involving the combination of both (self-selected intensity and music), especially in the elderly population. Thus, the aim of this study was to investigate the influence of music on performance, ratings of perceived exertion (RPE) and on affective and motivational responses of elderly during walking exercise with self-selected intensity. Eleven elderly performed walking sessions on an athletic track in three conditions: without music, with motivational music and with oudeterous music. RPE, mood states, motivation, affective responses, session RPE and attitudes related to the experience of exercise were evaluated. Results demonstrated that both motivational and oudeterous music improved affective responses and decreased RPE. However, only the motivational music condition showed an effect on distance walked, the only presenting a consistent increase in distance. Therefore, it is concluded that the use of music, particularly motivational music, besides increasing the distance walked, reduces RPE and increase pleasure of the elderly during the exercise. Such strategy, in addition to potentially impact adherence positively, can lead to greater benefits and physical adaptations related to the training in the long term

Desenvolvimento de métodos cromatográficos para a padronização do extrato de Eugenia speciosa Cambess

The use of medicinal plants is common in many Brazil's ethnic groups, because the diversity of plant species in the country is large. But the utilization of these plants as standardized herbal doesn't occur with de same frequency, due the lack of studies related to these therapies, classified as alternatives. Due to the high cost of some synthetic medicines for the treatment of chronic diseases, phytotherapy is a low-cost alternative and efficient, since the phytomedication has proven scientific studies and its production meets strict criteria for manufacturing and quality control to ensure its safety and efficacy. Among the medicinal species used for the treatment of chronic diseases, such as pain and inflammation, is Eugenia speciosa Cambess, popularly known as the bush laranjinha. Against this context, this paper held preliminary studies and developed the chromatographic profile of the hydroalcoholic extract of the leaves of E. speciosa by High Performance Liquid Chromatography coupled to photodiode array detector (CLAE-DAD). Preliminary qualitative results and the chromatographic profile have identified some metabolites classes present and some constituent as: homogentisic acid, homorientina, isovitexin and quercetrin

Comparação de dois métodos de quantificação de carga interna de treinamento em idosos

Tradicionalmente a prescrição de exercícios físicos é baseada unicamente em relação à carga externa. Entretanto, as adaptações fisiológicas em função do treinamento físico dependem da carga interna. Assim, a carga interna deve ser levada em consideração para uma otimização da prescrição exercícios físicos, principalmente durante exercícios em grupos que normalmente são utilizados para a população idosa. Porém, o envelhecimento parece acarretar em deteriorações na capacidade de interocepção, colocando em questionamento a validade de um dos principais métodos de quantificação da carga interna, o método que utiliza a percepção subjetiva de esforço (PSE). Desse modo, o objetivo do presente estudo foi comparar os métodos de quantificação da carga interna que utilizam a frequência cardíaca (FC), considerado o padrão-ouro para o presente estudo, com o método que utiliza a PSE na população idosa. Quarenta idosos praticantes de ginástica aeróbia (A) ou musculação (M) foram avaliados durante uma sessão de exercícios físicos. A determinação da carga interna pela FC e pela PSE foram realizadas através dos métodos de Edwards e de Foster, respectivamente. Os valores de carga interna (expressos em unidades arbitrárias) calculados pelo método da FC e PSE foram 69,4 ± 40,0 e 151,5 ± 83,5 para o grupo M e 73,3 ± 37,1 e 134,7 ± 41,6 para o grupo A, respectivamente. O valor de carga interna para os dois grupos em conjunto foi de 71,3 ± 38,2 pelo método da FC e de 143,1 ± 65,7 pela PSE. A relação entre os métodos foi determinada usando-se o coeficiente de correlação de Pearson para todos os participantes em conjunto (T), assim como para os grupos M e A. As correlações encontradas foram de r = 0,33 (p < 0,05) para T, r = 0,37 (p = 0,11) para M e r = 0,32 (p = 0,17) para A. A moderada correlação obtida coloca em questão a utilização do método da PSE para a quantificação de carga interna...

Qualidade de vida e atividade física em idosos

The aims of this literature review were to analyze the relationship between elderly quality of life - by means of the verification of the major measure instruments - with the physical activity, the sensibility of these questionnaires to the physical activity and the relationship between the type of physical activity and the quality of life in older persons. Comparisons of papers selected by the key words quality of life, exercise, and aging, reveal the components of quality of life assessed by the WHOQOL-BREF and SF-36 questionnaires. Based on the searched literature, we can conclude that: (i) active elderly seems to have better subjective perception of their quality of life than non active older persons; (ii) experimental studies did not showed strong evidence about the effects of physical exercise in the subjective perception of quality of life; (iii) none of the questionnaires is sensible to the practice of physical activity; (iv) the studies' results about the relationship between the type of physical activity and the elderly quality of life are inconclusive

Síndrome da disfunção cognitiva em cães

Cognitive dysfunction syndrome (CDS) is a progressive degenerative disorder of older dogs, characterized by a decline in cognitive function. The main clinical signs consistent with CDS are: disorientation, changes in socio-environmental interaction, sleep-wake cycle disturbance, changes in hygiene habits, urinate and/or defecate in unusual places, decreased physical activity, anxiety and eating disorders. There are no specific diagnostic tests for this condition in vivo, but alterations in neurological examination, cognitive tests and magnetic resonance imaging can be observed. The diagnosis is confirmed by histopathological examination of brain tissue. Diets rich in antioxidants, environmental enrichment with exercise and the use of selegiline and L-deprenyl have been recommended for the treatment of CDS.
