This study assessed the effects of Water training on the lipid profile and left ventricular structures in hyperlipidemic mice. Twenty-eight male LDLr-/- mice were randomly separated into 4 groups: sedentary, fed a standard diet (C); exercising, fed a standard diet (C+TRE); sedentary, fed a hyperlipidic diet (C+HL); and exercising, fed a hyperlipidic diet (E+HL). The exercising mice trained daily for 60 minutes during 60 days. After 48 hours of the end of the training period and 12 hours of rest fasting the animals were underwent euthanasia and the blood was collected for measuring the plasma levels of triglycerides, total cholesterol and its fractions (LDL, HDL, VLDL). The heart was removed and the left ventricle was weighed fresh to calculate the ratio left-ventricle weight (mg)/body weight (g). The results showed that the training was more effective in improving lipid plasma levels when combined with a balanced diet, thereby confirming that it is essential to associate physical exercise and diet. The training protocol resulted in eccentric left ventricular hypertrophy in the standard-diet group and decreased interstitial collagen deposition in the myocardium of the high-fat-diet animals, which may indicate an improved diastolic function with consequent improvement in the systolic function. It was concluded that regular moderate aerobic exercise induce beneficial and prophylactic adaptations to heart which promoted a better health condition and prevention to diseases.

Diabetes is a chronic disease that currently affects 171 million individuals approximately worldwide, with projection to reach 366 million people in 2030, increasing the prevalence of 2.8% in 2000 to 4.4%. The dyslipidemia is certainly one of the associated metabolic alterations most important, if we consider the main cause of death in Diabetes - the cardiovascular disease (CVD). One of the prevention and help factors in the Diabetes treatment and in the fall of associated complications is the physical exercise, which contributes to a better life quality to the diabetic. The main objective of the work was to evaluate the effect of a mixed physical exercises training program (aerobic/anaerobic with pause-active), including walking exercises, weightlifting and swiss ball, about possible changes in the blood lipid profile of adult individuals type 2 diabetics. The methodology used an experimental model of pre-test and post-test applied to the group. The data were first analyzed in a descriptive way for the normalization and the elaboration of averages and sample diversions. The sample was subdivided in two moments, being one pre and other post then weeks of training. After these procedures, the results of the values of the lipidic profile and glycemia were compared between the pairs pre and post training (test T Student, pair data), non-parametric. With the study, we can conclude that in despite of the low uptake of participants in the search, for reasons already cited, and the great age difference between them, the found results were partially satisfactory, because we achieved significant changes only in the glycemic variables, but we suggest future studies in the molds here proposed.

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.

You can set the resistance training such as making a move against a resistance by performing a muscle contraction and generating a muscular adaptation. This form of training, was initially used only in training athletes aiming to strengthen and improve fitness. Some coaches did not give proper focus, as the increase in muscle mass would cause loss of flexibility and agility. But over time a huge evolution occurred within this area and the practitioners of resistance training are no longer just athletes, and reached the whole community, from young to elderly, being a physical activity that generates a large caloric expenditure and has several health benefits, improve the cardiovascular system and decreasing the amount of body fat in the body. Cortisol is a hormone secreted from a stressful stimulus to the body, secretion undergoes control of the hypothalamic-pituitary axis, which releases the hormone into the bloodstream andrenocorticotrópico, going to the adrenal cortex responsible for their release. This has catabolic function, acting in the metabolism of carbohydrates, proteins and lipids, as well as having an important effect antiflamatório. Testosterone is a steroid hormone cholesterol from being produced by the testicles in men, as in women is produced to a lesser extent in ovary and adrenal glands, has functions androgenic and anabolic. Androgen function is responsible for the development of male sexual characteristics, while on anabolic function operates in the growth of muscles and bones, influencing the development of the human body organs. Within the metabolic changes that occur in the resistance training testosterone plays an important role in protein synthesis, influencing the production of strength and / or power during exercise. The objective of this work is through a literature review to assess the effects of resistance training on the production of these hormones and the relationship between them

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...

Objective: To present a model for research and training in multivisceral transplantation in pigs. Methods: Eight Large White pigs (four donors and four recipients) were operated. The multivisceral transplant with stomach, duodenum, pancreas, liver and intestine was performed similarly to transplantation in humans with a few differences, described below. Anastomoses were performed as follows: end-to-end from the supra-hepatic vena cava of the graft to the recipient juxta diaphragmatic vena cava; end-to-end from the infra-hepatic vena cava of the graft to the inferior (suprarenal) vena cava of the recipient; and endto-side patch of the aorta of the graft to the infrarenal aorta of the recipient plus digestive reconstruction. Results: The performance of the multivisceral transplantion was possible in all four animals. Reperfusions of the multivisceral graft led to a severe ischemia-reperfusion syndrome, despite flushing of the graft. The animals presented with hypotension and the need for high doses of vasoactive drugs, and all of them were sacrificed after discontinuing these drugs. Conclusion: Some alternatives to minimize the ischemia-reperfusion syndrome, such as the use of another vasoactive drug, use of a third pig merely for blood transfusion, presence of an anesthesia team in the operating room, and reduction of the graft, will be the next steps to enable experimental studies.

Recent research seeking to elucidate the possible effects of different types of physical training on the morphological adaptations of skeletal muscle. Although it is relatively easy to study the effects of exercise training in humans, such research becomes limited due to the invasive nature of the biopsies and the risk inherent in the use of human subjects. Thus, the application of animal models of training has been considered an appropriate strategy for the study of muscular adaptations in response to exercise. Objective: This study used a rodent model to determine the possible effects of aerobic and strength training on the CSA of fibers of the plantaris muscle. Methods: 24 male Wistar rats (80 to 120 days, 250 to 400 g) were randomly divided into 3 groups: aerobic training (TA, n = 8), strength training (ST, n = 8) and control (CO, n = 8). The animals in groups TA and TF were subjected to 8 weeks of training, while the animals of group C remained without any stimulus from start to finish the training period. At the end of the experiment, the animals were sacrificed and right plantar muscles dissected and removed. For morphological and morphometric analysis of muscle fibers was performed staining was performed H.E. Results: There was no significant difference in initial body weight between experimental groups. After 8 weeks of training, the TA group showed a significant reduction in final body weight, compared to CO and TF groups. With respect to the CSA of fibers of the plantaris muscle, no significant difference between the groups CO and TA. On the other hand, the strength training promoted a significant increase in AST of the group TF in compared with the groups CO and TA. Conclusion: Strength training used in this study promoted an increase in CSA of fibers of the plantaris muscle. On the other hand, animals submitted to aerobic training showed no changes in the CSA of the fibers, however, there was reduction in PC animals. The data strongly suggest the use of animal model of strength training used in this study as an appropriate strategy for studying the hypertrophic response of skeletal muscle.
