Cinética de lactato sanguíneo durante exercício de natação em ratos desnutridos recém-desmamados

Sabe-se que a desnutrição protéica fetal/neonatal pode predispor à resistência à insulina e à síndrome metabólica após recuperação nutricional. O treinamento físico, por sua vez, melhora a tolerância à glicose e a sensibilidade à insulina, além de exercer efeitos benéficos ao crescimento somático. Por outro lado, faltam informações quanto à habilidade de organismos desnutridos muito jovens para a realização do exercício. Modelos animais podem auxiliar a investigação desta questão, uma vez que o estudo em humanos apresenta limitações. Alimentação de ratos com dietas isocalóricas com baixo teor protéico é um modelo de desnutrição bastante utilizado para simular a desnutrição humana. Assim sendo, o presente estudo foi delineado para avaliar a cinética de lactato sanguíneo durante uma sessão de natação de ratos recém desmamados submetidos à restrição protéica fetal/neonatal. Foram avaliados dois grupos de animais recém-desmamados (21 dias, machos), contendo 8 animais em cada um: Normoprotéico (NP), crias de ratas alimentados com dieta normoprotéica (AIN 93G, 17% caseína) durante a gestação e a lactação e Hipoprotéico (HP):crias de ratas alimentados com dieta normoprotéica (6% caseína) durante a gestação e a lactação. Foram analisados peso ao nascer, concentrações séricas de proteínas totais e albumina dos recém-nascidos assim como ao desmame. Os dados foram analisados pelo teste t de student não pareado, sendo o nível de significância pré-estabelecido em 5%. Quando se avaliou os animais recémnascidos observou-se que a restrição protéica neonatal foi eficaz na instalação do quadro de desnutrição visto menores valores referente ao peso corporal, proteínas...

Sala de recursos para deficientes visuais: contribuições para o processo de inclusão escolar

This work is situated in the universe of resource rooms with a focus on the teachinglearning disabled students with low vision and visual in two cities of São Paulo. The paper discusses theoretically the historical emergence of these rooms, the deployment in the State of São Paulo and its importance within the context of school inclusion of students with visual impairments. Its purpose is to conduct a general survey of the operating conditions of the rooms from the perspective of the teacher of students. The results verified the contribution of this service as a complementary tool of the ordinary classroom, the use of specific instructional materials and overall educational performance of students. The results indicate that this type of specialized care while receiving criticism, does not promote segregation, but what about the educational needs of these students, who despite the lack of vision, school performance is equal to or better than the other students in the classroom common, it all depends on family support, and dedication to studies by the student. Research has shown students satisfied with the services provided in the resource room, as well as integration and good relationships between teachers and students. We could also highlight the importance of specific training and mastery of knowledge by the teacher to work with the visually impaired person. At the end the results were sent to the schools of this research object of study so that it can contribute to effective work in the educational process for visually impaired students in resource rooms

Motivação para a prática da natação competitiva

A prática esportiva oferece excelentes oportunidades para o enfrentamento de desafios, desenvolver habilidades, planejar metas a serem atingidas e participar de atividades variadas e complexas. Saber o que leva as crianças e os adolescentes à prática da atividade esportiva é importante, para que sejam criadas melhores estratégias de ensino e aprendizagem e para que o aluno mantenha-se motivado naquela modalidade, visto que aprendizagem e motivação são independentes no ser humano, sendo a motivação um dos temas mais abordados em Psicologia do Esporte. A natação é considerada um dos esportes mais completos, por trabalhar praticamente toda a musculatura ao mesmo tempo, além de auxiliar na melhoria da capacidade respisratória do praticante. Sendo assim, os objetivos do presente estudo foram analisar a relação entre motivação e natação, evidenciando os motivos que levam à prática da natação, tanto por crianças, jovens e adultos, verificar as razões pelas quais nadadores se mantém firmes em seus objetivos e indagas as causas da desistência de nadadores competitivos...

Natação e desenvolvimento motor em idade escolar

Swimming is a sport well suited to any age group, it worked properly when the individual stimuli that provides assist in human development. But water stimulation, is not something that is so easily in physical education in Brazil. Development corresponds to changes that occur throughout life, but that depends on the stimuli provided. Several studies have shown positive effects of swimming in relation to the child. This study aimed to verify if children swimmers and physical education classes have better motor development than those who do not practice the sport. Collection was done with two groups of 10 students between 9 and 11 years. As a group consisting of non-swimmers, and another formed by those that complement the physical education class with the regular practice of swimming. To develop the study was administered a battery of the proposed motor adapted Rosa Neto (2002) in which each child performed tasks corresponding to their chronological age (CA) and were only able to perform the task at a later age, when it was obtained successful in completing the task as originally proposed. At the end of the application of all statistical tests was done getting mean and standard deviation of the old motor (IM), calculated the ratio General Motor (MGQ) for the classification of the child's motor development and application of the t test with p <0.05 to observe the level of significance in the results. The results showed that the group swimmers had better agility tests which resulted in a difference between (IC) and (IM) higher compared with the non-practitioner. They also had higher average (MGQ), but these were not sufficient to classify the group into another level of development, however, by observing isolated cases, two children that practice would be a greater level of development. Through the t test was observed that the group swimmers had significant difference in balance ability. We conclude that the swimming group got positive overall...

Protocolos de natação em modelos experimentais com ratos

Exercise physiology has attempted to reproduce the experimental exercise in the laboratory using mainly rats. The swimming exercise has emerged as one of the leading research in these type ergometers. Thus, this research consisted of a literature review addressing the key issues which involve the exercise of swimming in the model rats. Training of aerobic and anaerobic swimming, evaluation models and models of periodization were the topics suggested in this research. In several studies, models of aerobic and anaerobic training have been proposed with the aim of studying their effect on normal and abnormal physiological parameters. However, earlier studies lacked methods of analysis aiming to determine the exercise intensity in the animal model. For this reason, in the last decade, assessment models have been adapted for humans to animals, especially rats. The maximal lactate steady state (MLSS) and lactate minimum (LM) are among the various techniques used to measure the amount of effort produced by swimming exercise in rats. Thereafter, based on biochemical parameters such as lactate, swimming exercise in rats has become the highest-rated, ie, using as reference the anaerobic threshold (AT). In another aspect, an entirely new line of research has tried to understand and promising swimming training in a periodized and its effects on some biochemical parameters. But this is an area little researched so far. Thus, the experimental model of swimming has proved an important resource of exercise physiology. From this model, it becomes possible to study the exercise, especially swimming, in more accurate, based on invasive and incisive analysis of the rat

Chá mate melhora a resistência à natação e reduz o dano oxidativo induzido pelo exercício em ratos submetidos à única sessão de natação

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.

As fases do treinamento de natação influenciam os substratos energéticos, cortisol e leucócitos

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.

Alterações antropométricas de lesados medulares após treinamento intervalado em natação

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.
