Several nutritional interventions are performed in order to reduce the impact of EO induced by exercise. Some studies suggest that mate tea (CM) have compounds, which can act as antioxidants reducing EO. The aim of this study was to evaluate the effect of CM induced under the EO after a single bout of aerobic exercise. Methods: We used male Wistar rats (50 days and 200g) distributed in four experimental groups: control (CON); mate tea (CM), Swimming (N); Swimming+mate tea (N + CM) . The CM and N+CM groups received CM diluted in distilled water at 96 ° C for five days, oropharyngeal route (50 mg / kg body weight, 0.5 mL). Both groups were adapted to the aquatic environment prior to experimental day, after a single swimming session, with 5% of body weight attached to the tail, until the animals reached exhaustion. Immediately after the state of exhaustion, peripheral blood was collected for further analysis. Results: The animals of the group N + CM showed improved resistance swimming compared to group C (p < 0.0001). No increase in lipid oxidative damage and production of lactate in group N + CM , compared to group N , may be attributed to the significant increase in plasma uric acid concentrations demonstrated in this study was observed . Conclusion: Therefore, the results indicate that consumption of CM may be natural strategy for improving aerobic exercise endurance and reduce the impact of EO induced by aerobic exercise.

The effect of physical exercise in immune function has been extensively studied. The intensity and duration of physical exercise have considerable influence in immunologic parameters. However, few studies have compared different exercise intensities in different stages of a physical training program. Thus, the aim of this study was to verify the metabolic, hormonal and immunologic changes before and after acute intermittent swimming exercise, following different stages of training program. Seventeen male swimmers were evaluated in three stages of training. The intensity of the three sessions was 90% (anaerobic potency – PAN), 70% (aerobic potency - PAE) and 98% (lactate tolerance – TLA) of the maximal speed from the best time of the distance, resulted from peak performance in competition. Blood samples were collected pre and immediately after exercise for cells counting and measurement of substrates and cortisol concentrations. It was used ANOVA to verify the significance of difference (p<0.05). There was a significant increase of glucose and cortisol post exercise in the PAN and PAE sessions. Glutamine increased significantly in PAE and TLA. Leukocytes increased significantly after the three different sessions and lymphocytes decreased significantly on PAE and TLA. In conclusion, it was demonstrated that changes of the several parameters studied in different stages of training program can cause temporary alterations in immune cells and may compromise resistance to common minor illnesses and athlete performance.

The goal of this study was to assess the alterations in some anthropometric measures of sedentary subjects with spinal cord injury after a swimming interval training program with the use of a lifejacket. The study included 17 male spinal cord injured subjects, divided into two groups: 11 subjects in the training group (TG) and 6 in the control group (CG).The protocol employed a stroke of breaststroke, in work periods of moderate to severe, and stroke in the back stroke in periods of active recovery. An anthropometric evaluation was applied before the application of the training protocol and another (reevaluation) after 8 weeks. In the TG, the results obtained after the swimming program showed a significant change (p < 0.05) in the supra-iliac (SICF) and in the triciptal cutaneous folds (TCF), arm and waist circumference measures, from the first evaluation to the reevaluation. In the CG there were no significant changes observed in any of the variables studied. When comparing the two groups after the swimming training program, the average of the variable SICFT in the TG was significantly lower than the average for the CG. Generally speaking, the out comings showed the swimming protocol efficiency in promoting desirable anthropometric changes in spinal cord injured subjects while a reduction of fatty tissue in the arms and abdominal region and an increase of muscular tissue in the upper limbs of those subjects also occurred.

The swimming is one of the most suitable activities for the stimulation of People with Desabilitie (PWD), we want it isfor the freedom of corporal action for those that possess motive limitation, as well as, for the discovery need, corporal adaptation inthe aquatic way. This way, in the academies that develop this activity it is waited we find PWD inserted in the classes. The objective ofthis study was to verify the inclusion process it is happening in the academies of swimming of the city of Bauru-SP. A field research wasdeveloped, of qualitative character and of exploratory stamp, where they were contacted the academies that taught swimming initially andthose that they were disposed to participate in the research, in a total of 10 academies. We verified that, of a total of 3105 people enrolledin the swimming classes in the academies 19 they were only PWD, in other words, 0,61%. Although the inclusion process is found in theswimming academies, this is very limited.

Este trabalho aborda a natação para a pessoa com deficiência (PCD), tendo como objetivo verificar o nível de desempenho aquático de participantes do projeto de ensino de natação adaptada. Destacamos o intuito de avaliar a perspectiva de início de um treinamento paralímpico em natação. Foram analisados 14 usuá- rios da Sorri-Bauru, vinculados a um programa de iniciação, quanto ao seu nível de desempenho na água. Verificamos que a grande maioria ainda encontra-se em fase inicial da aprendizagem dos estilos, onde a respiração e a autonomia no meio líquido ainda necessitam ser amplamente dominadas. Porém, a partir dos resultados é possível propor o início do processo de treinamento criando um vínculo entre a PCD e o professor/técnico e que sejam respeitadas as limitações e potencialidades dos participantes.

The objective of thisstudy was to verify, using the Ecological Development Theory (EDT), as the practice and swimming learning for People With Disabilities (PWD) causes changes to both the practitioner and in other environments experienced by it as well as the other environments influence the learning to swim. The study included 16 PWD, students linked university extension project, Department of Physical Education of UNESP Bauru, taught by coordinators LAPEF, which aims to includes wimming in the PWD ofevery day life, students linked to an institution of Bauru-SP, three employees of the institution and two swimming project teachers.Interviews with the families of the students were made, with the institution s employees, with the project teachers and analyze thes wimming lessons applied in the project for one semester. Based on the results we can say that the practice and learnings wimming for PWD causes changes to both the practitioner and for other environments experienced by her (home, institution) and also, what other environments experienced by PWD influence in practice and process of learning to swim. Using the terminology of EDT, we conclude that theme so system (home activities institution) influences in the microsystem (swimming lessons) and the microsystem influences the mesosystem, so the activity was significant and temporal persistence influencing the development of PCD.

A Vincristina (VCR) é um quimioterápico amplamente utilizado na clínica. Entre os efeitos colaterais descritos, devido a sua toxicidade, estao às alteraçoes do equilíbrio e na coordenaçao motora. O presente estudo tem como objetivo avaliar o efeito do exercício aeróbico prévio (6 semanas de nataçao, 1h/dia, 5 dias/semana, sobrecarga de 5 do peso corporal) em aspectos comportamentais de ratos Wistar tratados com o quimioterápico Vincristina. A administraçao da Vincristina foi realizada com dose única semanal de 0,5mg/kg, durante duas semanas, com dose acumulada de 1mg/kg, via intraperitoneal. Um dia e 7 dias depois de cada dose os ratos foram avaliados com testes de equilíbrio (Rotarod), de exploraçao (Campo Aberto) e de força muscular (Grip-Test). Observou-se uma diminuiçao significativa do equilíbrio corporal e do comportamento exploratório nos ratos expostos à vincristina com proteçao significativa do exercício físico. Nao houve diminuiçao significativa da força muscular nos ratos tratados com VCR, porém o exercício por si só aumentou a força muscular e a distancia percorrida pelos ratos que fizeram nataçao. Portanto, o exercício físico mostrou-se protetor contra a perda de equilíbrio e diminuiçao da exploraçao observada nos ratos expostos ao quimioterápico

Para se preparar e projectar a época desportiva existem um conjunto de factores a ter conta para que todo o processo não esteja condenado ao insucesso logo à partida. Deste modo, assume capital importância, a programação da atividade a desenvolver ao longo das semanas que compõem a época desportiva. Cabe ao Treinador essa mesma programação, ao mesmo tempo que deverá projetar um conjunto de acções que visem o correcto acompanhamento do que foi planeado, e proceder às respectivas alterações, se assim for necessário. O trabalho apresentado insere-se no âmbito do relatório final de estágio 2ºAno de Mestrado em Treino Desportivo, vertente de Natação Pura desportiva, e visa ser uma descrição do trabalho desenvolvido junto da equipa Absoluta da GesLoures, E.M. A estrutura do trabalho irá basear-se, na análise da atividade por mim desenvolvida em termos de organização do treino da equipa Absoluta da GesLoures E.M., mas centrando-se mais em concreto no acompanhamento da atleta Nádia Vieira.
