Efeito crônico do alongamento estático sobre a capacidade funcional de idosas

Durante o processo de envelhecimento ocorrem alterações morfofisiológicas que podem acarretar em dificuldades na realização de atividades da vida diária (AVDs), diminuindo conseqüentemente a independência do idoso e comprometendo sua qualidade de vida. Para atenuar e/ou retardar tais alterações, diversos autores têm recomendado a prática regular de atividade física voltada para o desenvolvimento dos componentes de capacidade funcional (CF). Especificamente para a flexibilidade, a realização de exercícios de alongamento tem sido amplamente recomendada pela literatura. De qualquer forma, poucos estudos analisaram o efeito crônico do treinamento da flexibilidade em diferentes volumes sobre a CF de idosos. Desta forma, o objetivo desse estudo foi analisar o efeito de 16 semanas de treinamento de flexibilidade, através de alongamento estático, realizado com dois diferentes volumes, sobre a CF de idosas. Participaram deste estudo 23 mulheres (67,4 ± 7,3 anos; 64,9 ± 8,7 kg; 155,1 ± 5,8 cm; 27,5 ± 3,5 kg/m2) divididas em dois grupos: Grupo Treinamento de 30 segundos (GT30, n=15) e Grupo Treinamento de 60 segundos (GT60, n=8). As participantes do GT30 e GT60 foram submetidas ao treinamento de flexibilidade, com duração de 16 semanas e freqüência de três vezes semanais. Durante cada sessão de treinamento, as participantes realizaram três séries de exercícios de alongamento para os grupos musculares de membros superiores, inferiores e tronco, com intervalo de 30 segundos entre as repetições e entre os exercícios. A CF foi avaliada por meio da bateria de testes motores da American Alliance for Health, Physical Education, Recreation and Dance (AAHPERD) tanto no momento pré quanto após oito e 16 semanas de treinamento. Para o tratamento dos dados foi utilizada estatística descritiva (média e desviopadrão), test t de Student para amostras independentes... (Resumo completo, clicar acesso eletrônico abaixo)

Efeito agudo de diferentes volumes de alongamento estático na contração voluntária máxima de idosas

Several studies have shown that different stretching routines can lead to decreases on acute neuromuscular system performance. Although the deficit in muscle strength mediated by different methods of stretching has been systematically observed, few studies have investigated the possible existence of a dose-response relationship between the amount of stretching and muscle strength deficit in older adults. In this context, the objective of this study was to investigate the acute effect of two different stretching volumes on isometric force-time curve (Cf-t) in elderly women. The study included 13 older women (64.08 ± 4.27 years, 69.98 ± 10.56 kg, 157.90 ± 8.66 cm, 28.25 ± 4.22 kg/m²). The participants visited the laboratory for five consecutive days, among which the first two were used for familiarization. During the other three days the participants underwent experimental conditions: control (C) stretch 30 seconds (AE30) and stretch 60 seconds (AE60). For the AE30 and AE60 conditions, three series of passive static stretching were performed, with duration of 30 and 60 seconds, respectively. The experimental conditions were performed with an interval of at least 24 hours between them and the order of execution was randomized. The recording of isometric Cf-t of the knee extensor muscles was performed in extensor chair connected to a force transducer. Measurements were recorded immediately after each experimental condition, for five seconds. For statistical analysis, descriptive procedures were used and ANOVA one way to check possible changes on the Maximal Voluntary Contraction (CVM) and Peak Rate of Force Development (TDFP) among the three conditions (p <0.05). The ANOVA showed no statistically significant difference for CVM and TDFP, between the three conditions. It can be concluded that different volumes of static stretching, three sets ...(Complete abstract click electronic access below)

O ensino da recepção estético-lierária e a formação humana

In this article are defended the possibility and the necessity of the teaching of the reception of art works in school education. Firstly, some relations between art and the development of both the human species and the individual are analysed in Georg Lukács and Lev Vygotsky’s works. In order to put in question the old assumption that opposes education and instruction, the discussion made by Gramsci on the grammatical teaching of Latin and Greek in the traditional school education is explored. In the article is concluded its path analysing the intentional and systematic formation of the reception of art works provided by school education based on Aleksei N. Leontiev’s works on the appropriation process of culture by the individual.

Importância do tratamento estético periodontal na reabilitação protética

Gingival recession is a common deformity that affects a large number of people. This condition is frequently associated with esthetic complains and may lead to dental hypersensitivity. Thus, various surgical procedures have been proposed to provide root coverage. Since the 1950s, free and pedicle gingival grafts have been greatly used for treating gingival recession. However, after the 1985 Miller gingival recession classification, and with the development of other appropriated techniques that use subepithelial connective tissue grafts, gingival recession treatments have resulted in more predictable outcomes, especially with respect to Class I and II sites, i.e., in the absence of interproximal bone loss. This article reported the importance of aesthetical periodontal treatment in the prosthetic rehabilitation of a patient with a class I gingival recession with 3 mm of vertical extension in the superior canine. The treatment plan consisted of root coverage using subepithelial connective tissue graft (SCTG) associated with construction of new prosthesis.

Tratamento estético periodontal: revisão de literatura sobre alguns tipos de cirurgias

Currently, periodontal aesthetics has been prized for harmony of the smile. The clinical crown lengthening, gingival excess or altered passive eruption, is effectively corrected by periodontal surgery. The purpose of this paper is to show, through a literature review, some types of surgery on clinical crown lengthening and root coverage. Clinical crown lengthening is done to Change the size of the anterior teeth and to optimize the cosmetic result of treatment with new coronal restoration and other cosmetic dental care. In general, the treatment plan and the choice of operative technique begin with careful clinical examination. Recessions tissue can be defined as a displacement of the gingival margin toward the junction mucogingival exposing the root surface. These, when present, impacting on patient comfort by providing the occurrence of cervical dentin hypersensitivity, and the esthetic, the amendment of the gum line. Successful treatment of recessions is based on knowledge of its etiology and assessment of predictability of surgical techniques that aim to root coverage. Through literature review, we can conclude that the types of surgery most often used are: 1) to increase the clinical crown, gingivectomy, flap surgery and gingivoplasty osteotomy, and 2) for root coverage, the use will depend on the amount of gum keratinized and especially the classification of Miller.

Associação de facetas diretas e fibra de reforço para restabelecimento estético do sorriso: relato de caso clínico

Esse artigo tem como objetivo demonstrar o restabelecimento estético do sorriso obtido por meio da associação de facetas diretas e fibra de reforço. As fibras de reforço são utilizadas como alternativa para substituição de elementos dentários perdidos e possuem indicações precisas, sendo empregadas em diversas especialidades da Odontologia, devido à sua capacidade de aumentar a resistência à tração dos compósitos, o que aumenta a resistência à compressão das fibras. Para o completo restabelecimento do sorriso, muitas vezes é necessário reanatomizar os dentes adjacentes, considerando as condições em que esses se apresentam. Sendo assim, o profissional deve ter conhecimento para aplicação correta da técnica e restabelecimento da estética ao paciente.

Enceramento diagnóstico: previsibilidade no tratamento estético indireto

Trata-se da reprodução em cera realizada a partir de um modelo de estudo e tem como finalidade observar, em três dimensões, a futura forma final dos dentes, ajudar visualmente na realização do preparo dentário e demonstrar ao paciente o resultado final do tratamento antes mesmo de iniciá-lo, obtendo-se, assim, máxima previsibilidade. O objetivo desse artigo é mostrar, através de casos clínicos, a previsibilidade no tratamento restaurador indireto obtida por meio do enceramento diagnóstico.

Reabilitação estético-funcional sobre implantes agulhados e endósseos

This report shows the resolution of a case study whose aim was promote the aesthetic and functional rehabilitation of upper left hemi-arch over endosseous and needle implant prostheses. To improve the position of the needle implants, we performed the bucco-palatal bending of needles splinting them with composite resin; we removed the screwed implant prosthesis in the regions of the premolars (24 and 25) and molar (26). The mini-abutments of the last two implants were replaced, and in the first premolar and canine, we used cemented abutments due to implant angulation having planned soldering because of implant size and contact with one needle implant that could interfere with intimate contact bone/implant damaging biomechanics. Pick-up impressions were performed with an open tray, using a retractor cord in the needle implants and respective transfer copings. Therefore, models were related on semi-adjustable articulator after a face-bow recording and interocclusal indexes. After working cast fabrication and try-in of infra-structures, these were adjusted and related into the articulator again. Then, after ceramic build-up, adjustments, finishing, and torque, chemically-activated resin cement was applied on units 21 to 24. At the end of the case, we concluded that a good aesthetic and functional rehabilitation depends on thorough knowledge of techniques for each clinical situation.

José Veríssimo e a construção do cânone literário brasileiro: um ponto de vista estético

This essay analyses the História da literatura brasileira (1916), of José Veríssimo, that from a rupture with the romantic criticism or with the interpretation of the Scientifics method of taking as a basis a theoretical eclecticism that makes him distrust the enclosed methods and the restrict classifications. From ethnological valorization to Nationalist sentiment or from Scintificism to the support of the esthetics in the building of a Brazilian literary canon, José Veríssimo’s critical works are featured by an organicity that generates his refined criteria
