The beneficial effects of exercise in rodents are preserved after detraining: a phenomenon unrelated to GLUT4 expression

Abstract: Although exercise training has well-known cardiorespiratory and metabolic benefits, low compliance with exercise training programs is a fact, and the harmful effects of physical detraining regarding these adaptations usually go unnoticed. We investigated the effects of exercise detraining on blood pressure, insulin sensitivity, and GLUT4 expression in spontaneously hypertensive rats (SHR) and normotensive Wistar Kyoto rats (WKY). Studied animals were randomized into sedentary, trained (treadmill running/5 days a week, 60 min/day for 10 weeks), 1 week of detraining, and 2 weeks of detraining. Blood pressure (tail-cuff system), insulin sensitivity (kITT), and GLUT4 (Western blot) in heart, gastrocnemius and white fat tissue were measured. Exercise training reduced blood pressure (19%), improved insulin sensitivity (24%), and increased GLUT4 in the heart (+34%); gastrocnemius (+36%) and fat (+22%) in SHR. In WKY no change in either blood pressure or insulin sensitivity were observed, but there was an increase in GLUT4 in the heart (+25%), gastrocnemius (+45%) and fat (+36%) induced by training. Both periods of detraining did not induce any change in neither blood pressure nor insulin sensitivity in SHR and WKY. One-week detraining reduced GLUT4 in SHR (heart: -28%; fat: -23%) and WKY (heart: -19%; fat: -22%); GLUT4 in the gastrocnemius was reduced after a 2-week detraining (SHR: -35%; WKY: -25%). There was a positive correlation between GLUT4 (gastrocnemius) and the maximal velocity in the exercise test (r = 0.60, p = 0.004). The study findings show that in detraining, despite reversion of the enhanced GLUT4 expression, cardiorespiratory and metabolic beneficial effects of exercise are preserved.

Validação do questionário de burnout para atletas

Abstract: The burnout syndrome can be defined as a reaction to chronic stress This study aimed to validate a burnout questionnaire for athletes of Portuguese language Four methodologically steps were followed: Back Translation of the Athlete Burnout Questionnaire to the Portuguese language, what led to the “Questionario de Burnout para Atletas” (QBA); QBA’s validation, through construct validation (factor analysis), and, finally, the QBA’s reliability The data found confirmed both the QBA’s construct validity (the instrument represents exactly the interest concept) and reliability (the instrument measures effectively what it purposes to measure) The findings of this investigation let us conclude that QBA is considered an appropriate instrument for the burnout measurement in high level Brazilian athletes

Capacidade funcional do idoso: formas de avaliação e tendências

Abstract: A avaliacao da capacidade funcional (CF) dos idosos pode detectar possivel risco de dependencia futura, estabelecer niveis de morbidade de mortalidade, alem de poder balizar intervencoes direcionadas aos idosos. Dessa forma, o objetivo desse estudo foi, atraves de uma pesquisa bibliografica, identificar os testes mais utilizados e o potencial de cada prova para identificacao do nivel de CF do idoso. O exame da literatura mostrou que CF tem sido determinada em abordagens gerais, que objetivam tracar o perfil funcional atraves de um unico teste, como as propostas dos testes caminhada e de mobilidade. Por outro lado, pode-se determinar a CF mediante a avaliacao de componentes especificos como os testes de equilibrio, forca e marcha. Geralmente, as propostas descritas seguem a ideia de que uma acao funcional, realizada de maneira mais rapida, remete ao potencial funcional do idoso. No entanto, mediante as limitacoes das quantificacoes apontadas pelos estudos, observou-se a tendencia da avaliacao funcional em utilizar analises qualitativas, que objetivam determinar o padrao de movimento, como uma outra via da compreensao da CF do idoso. Alem disso, notou-se que a avaliacao da CF tem sido indicada e desenvolvida tambem para aqueles que nao apresentam comprometimento funcional aparente e nao somente para os idosos evidentemente mais frageis.

Um panorama analítico-comportamental sobre os transtornos de ansiedade

Abstract: This work aims to present an analysis from the standpoints of Skinner's radical behaviorism about the variables involved in the psychiatric problems denominated as anxiety disorder. At first, anxiety is defined as a clinical phenomenon and as a theoretical construct. The behavioral literature emphasizes avoidance and elimination responses, and the selection of standardized therapeutic procedures due to that emphasis. They are then discussed considering the current non-observance of other environmental relevant variables. The article suggests that other functional relationships than avoidance can be detected, as focus of the intervention. Respondent and operant relationships that compose the client's behavior repertoire that is diagnosed as anxiety disorder are analyzed, including the interaction among operant and respondent contingencies, aversive control, stimuli control, superior order response classes and establishing operations such as privation and aversive stimulation. At last, a model that integrates the relationships involved in the clinical patterns in focus is presented and possible therapeutic strategies are suggested.
