Treinamento físico durante a recuperação nutricional não afeta o metabolismo muscular da glicose de ratos

O presente estudo visou avaliar a ingestão alimentar, ganho de peso e metabolismo muscular da glicose em ratos submetidos ao treinamento aeróbio durante recuperação de desnutrição protéica. Para isso, 60 ratos da linhagem Wistar, machos, foram separados nos grupos normoprotéico (NP) e hipoprotéico (HP), de acordo com a dieta NP (17% de proteína) ou HP (6% de proteína), respectivamente, recebida do desmame (21 dias) aos 90 dias de idade. Todos os animais passaram então, a receber a dieta NP e foram submetidos (treinado TRE) ou não (sedentário - SED) ao treinamento físico, que consistiu de corrida em esteira rolante, 25m/min, 50 minutos ao dia, cinco dias na semana, durante 30 dias, compondo os grupos NP-SED, NP-TRE, HP/NP-SED e HP/NP-TRE. Foi avaliado o metabolismo da glicose em fatias de músculo sóleo incubado em presença de insulina (100miU/L) e glicose (5,5mM, contendo [C14] glicose e [H³] 2-deoxiglicose). A ingestão alimentar diária (g/100g de peso corporal) do grupo HP/NP-TRE (24,39 ± 4,07) foi maior do que o grupo HP/NP-SED (21,62 ± 4,69). O ganho de peso (g) foi semelhante nos grupos HP/NP-TRE (203,80 ± 34,03) e HP/NP-SED (214,43 ± 30,54). Não houve diferença entre estes dois grupos quanto aos parâmetros: captação de glicose, oxidação de glicose e síntese de glicogênio pelo músculo sóleo. Desse modo, pudemos concluir que o treinamento aeróbio não teve impacto sobre a recuperação nutricional, visto que não houve diferenças metabólicas ou somáticas entre animais recuperados em presença ou ausência do treinamento.

Jogos recreacionais em treinamentos empresariais

Due to the growing practice of recreational activities among enterprises, it became evident an increase in the possibilities of interdisciplinary action of Physical Education teachers as well as in the areas alike. However, just a few academic papers try to understand the relation involving recreational activities in the context of business companies, what motivated the attention of this study, which aims to investigate whether the games played in business trainings may somehow contribute for a better comprehension and development of actions between employees and employers and also, to analyze the acceptability of this resource in lectures or formal events, which are usual in trainings. This study – which has a qualitative approach – was developed and based on the union of both bibliographic and exploratory researches. Data were collected through a questionnaire with open and direct questions that was applied to an intentional sample of twenty-five employees from a company in the countryside of São Paulo. Those data were analyzed in a descriptive way, through Thematic Content Analysis Technique and they showed that the relationship among employees has improved, whereas the relationship between employers and employees hasn’t improved that much and that the training which was given with dynamics and recreational strategies had a very positive result, because the goals were reached and the acceptability of this kind of training was unanimous among all the participants, It is extremely important that recreational activities can be developed in business trainings because with them, it is possible to reach more successfully their goals and the acceptability by the participants.

A política externa estadunidense no atual quadro político sul-americano

The central thesis that we aim to survey in this paper is that the present South-American political scene has required of the American imperialism a strategical redesign, in the sense of the neutralization, weakening and, if it is possible, destruction of regional political experiences/tendencies not aligned to its foreign politics. Under the mask of the defense of democracy and beneath the argument that Latin American "market oriented politics" are at stake, due to questions that goes back from the "delin-quency" —in Mexico—, the global terrorism, the organized international crime up to the worldwide drug traffic, the global strategy of American imperialism then sets up the definition of a new doctrine of preventive war that justifies the utilization of hard power against any country, in the name of its own defense. At the heart of the question what —actually— is in the agenda is the defense (and reproduction) of the benefits of its multinationals corporations and financial capital, by means of the international sub-traction of profitable assets, such as financial, energetic, communicational and natural resources, in addition to the domination of local markets, beyond facilitating capital flee amongst others.
