ABSTRACT
O presente estudo teve como objetivo verificar a influência do exercício físico e da atividade física nos aspectos psicológicos (índices indicativos para depressão e ansiedade) em idosos. Para tanto, foram selecionados 54 idosos saudáveis (66,85 ± 4,42 anos), de ambos os sexos, que foram subdivididos em 3 grupos: Grupo A controle (indivíduos sedentários), n=18; Grupo B grupo de desportistas (indivíduos sedentários que passaram a praticar exercícios físicos regularmente), n=18; Grupo C grupo de lazer (indivíduos que participam de programas de atividade física não sistematizada) n=18. Os voluntários foram submetidos a uma avaliação inicial, na qual foram aplicados questionários que medem escores indicativos de depressão (Inventário Beck) e ansiedade (Idate Traço e Estado), também foram realizados um teste ergométrico com eletrocardiograma para estimativa do VO2 e exames laboratoriais. Após esta fase, os voluntários do Grupo B iniciaram um programa de exercício físico por um período de quatro meses sendo então reavaliados seguindo o mesmo protocolo inicial. Os resultados revelaram que o Grupo de desportistas obteve um índice satisfatório significativo de redução dos escores de depressão (Inventário Beck), passando de leve para normal, e em relação aos índices indicativos para ansiedade (Idate Traço e Estado) e os dados se demonstraram baixos em todos os grupos analisados. Os resultados sugerem que a prática regular de exercício físico orientado com parâmetros fisiológicos, pode contribuir na redução dos escores para depressão e ansiedade em indivíduos com mais de 60 anos.
The purpose of the present study was to verify the influence of physical exercise and physical activity over psychological aspects (indexes for depression and anxiety) in elders. For this study, 54 healthy elders (66,85 ± 4,42 age) of both sexes were randomly allocated in three groups: Group A Control group (sedentary individuals) n=18, Group B Sportsmanlike group (sedentary individuals who started to practice physical exercises regularly) n=18, and Group C Leisure-time group (individuals who participate in programs of unsystematized physical activity) n=18. The volunteers were submitted to an initial evaluation, in which questionnaires that measure indicative scores of depression (Beck Depression Inventory) and anxiety (Idate Trait and State) were applied; an ergometric test with an electrocardiogram for the estimate of max VO2 and of laboratorial exams was also made. After this phase, Group B volunteers began a physical exercise program for 4 months, being reevaluated through the same initial protocol. The results revealed that the Sportsmanlike group obtained a significantly satisfactory index of decrease in depression scores (Beck Depression Inventory), going from light to normal, as well as in scores indicating anxiety (Idate Trait and State); also, data proved to be low in all analized groups. The results suggest that regular practice of physical exercise, oriented through physiological parameters, can help to decrease depression and anxiety scores in individuals above the age of 60.

PURPOSE--To evaluate possible morphological changes in chronic chagasic of the right bundle trabecular branch (RB) with right branch block (RBB) and to draw clinicopathological correlations. METHODS--Eight RBB chronic chagasic septo-marginal trabeculae (SMT) (group A), six left branch block (LBB) chagasic SMT (group B) and six SMT from non-chagasics with no heart disease (group C) were analyzed. Every SMT was completely embedded in paraffin, sub-serially sectioned to the end of the paraffin-block and the sections were processed for pathological study. RESULTS--Right bundle branch trabecular segment mononuclear infiltrate and/or fibrosis were found for 87.5 (7/8) of group A, 50 por cento (3/6) of group B and 16.6 por cento (1/6) of group C. Moderate mononuclear infiltrate and fibrosis were noted respectively for 3 and 1 cases, from group A. For the remaining group A cases and for all the group B and C cases the mononuclear infiltrate and fibrosis were slight. CONCLUSION--The frequency and degree of RB lesions might explain some of RBB. On the other hand, the absence of lesions in one case RBB and the slight degree of RB lesions in chagasics with LBB and in one non-chagasic case indicate that sometimes it is not possible to establish electrocardiographic-pathological correlations after TSM histological examination
