Introduction: Many nervous system tissues and cells suffers positive changes when faced to exercise training. However, data on vagus nerve adaptation from exercise-induced study is absent. Objective: To analyze the effect of an endurance training on the vagus nerve morphology of rats. Methods: Wistar rats (6 months of age) were divided into two groups: control group (CG, n=8), and aerobic trained group (AT, n=8). AT was submitted to a treadmill training program of five times per week during 12 weeks. The maximum speed stipulated in the training protocol corresponded to 60% of the mean maximum intensity achieved by the group in the test of maximum effort. Results: Twelve weeks of treadmill training resulted in left ventricular hypertrophy in the AT group compared to CG. There was a significant increase in the area of both the myelinated and unmyelinated axons, and in the area of myelin sheath with training. The number of neurotubules and neurofilaments in myelinated fibers of aerobic trained group was significantly greater than CG (p≤0.05). Conclusion: Endurance training promoted significant increase in morphometric parameters of the vagus nerve in the same way it affect somatic nerves.
Several studies have demonstrated that alcohol consumption can decrease bone density and alter its structure. However, most of the studies did not investigate the effects of specific alcoholic beverages. This study determined the effects of chronic consumption of cachaça (a Brazilian beverage containing alcohol) on body weight (BW), tibia bone density and on the tibia collagen density in middle-aged Wistar rats. Rats with 9 months old were submitted for 100 days, to a liquid diet of cachaça diluted in water with a progressive and controlled concentration (10°GL, 15°GL, 20°GL, 25°GL, and 30°GL). Chronic cachaça intake produced a significant decrease in BW and altered bone remodeling, decreasing trabecular bone density. In chronic cachaça-treated group (CT), the production of collagen fibers in bone tissue has predominantly green birefringence. It appears that they are immature fibers that do not exist in the control group, in which there are standard predominantly yellowish mature fibers. In conclusion, chronic cachaça consumption affects the structure of the tibial bone of middle-aged rats by decreasing the bone density and reducing the density of mature collagen fibers.
RESUMOO futebol é um dos esportes que mais possuem incidências de lesões. A pesquisa teve como objetivo verificar a incidência de lesões em atletas no clube "Associação Portuguesa de Desportos" da série A2 durante o campeonato paulista, dentre os objetivos específicos foram de avaliar os principais índices e diagnósticos de lesões ocorridas, analisar incidência de lesão por posição dentro de campo e avaliar tempo de afastamento gerado por tais. Foi realizada uma análise de prontuários do setor de fisioterapia do clube durante o campeonato paulista A2. Os principais resultados foram 93.5% de lesões em membros inferiores, sendo 87% lesões musculares da coxa, joelho 12.9%, tornozelo e posteriores de perna 9.6%, dessas lesões 32% foram de lesões recorrentes e 68% nova lesão. Conclui-se que a incidência de lesão foi alta levando em consideração somente um campeonato de uma equipe.
A incontinência urinária (IU) é definida pela International Continence Society (ICS) como qualquer perda involuntária de urina, sendo mais prevalente no gênero feminino (MARKLAND et al., 2011). Dentre os principais tipos de IU, estão a incontinência urinária de esforço (IUE) que é caracterizada pela perda involuntária de urina durante esforço físico e geralmente ocorre em situações de tosse, risada, espirro e durante a prática de atividade física, a incontinência urinária de urgência (IUU) que é definida como a perda involuntária de urina associada a um forte desejo de urinar, ou seja, quando não há capacidade de controlar o mecanismo de micção e a incontinência urinária mista (IUM) que ocorre quando os sintomas de ambos os tipos de incontinência urinária estão presentes (HAYLEN et al., 2010).
