Efeito de 13 semanas de treinamento físico militar sobre a composição corporal e o desempenho físico dos alunos da escola preparatória de cadetes do exército

INTRODUCTION: Armies from all over the world acknowledge the importance of good physical fitness for the performance of military duties. The Military Exercise Training (MET) attempts to provide assistance to this search for better physical fitness and performance. OBJECTIVE: To verifying the effect on the body composition and physical performance of the students at ESPCEX (Military School for Preparation of Army Cadets) after 13 weeks of MET. METHODS: The sample was formed by 287 male students from the ESPCEX, whose average age was 18.33 ±1.26. Such students accomplished a boarding school routine, having defined schedules, meals and activities from which they were only released during the weekends. The MET was accomplished five days a week and it comprised both aerobic and resistance training. Measurement of body mass, height, skinfold (triceps, abdominal and suprailiac) was accomplished during pre and post training periods, and the following tests were performed: 12-minutes-run, oblique sit up, arm push up and pull up. Fat percentage, fat-free body mass and fat body mass were calculated using the anthropometric data based on the Guedes 3 skinfold protocol. RESULTS: Significant reduction in fat body mass, fat percentage and in triceptal and abdominal skinfold, as well as increase in suprailiac skinfold and fat-free body mass was observed when anthropometric and body composition data were compared, during the initial and the final periods of training. Significant improvement also occurred in all prformed physical tests, in which better performance was achieved. CONCLUSION: The acquired data suggest that performance of MET 5 days a week brought significantly improved body composition as well as physical performance

A língua inglesa no ensino fundamentl I público: diálogos com Bakhtin por uma formação plurilíngue

This article aims at discussing the contributions of the Bakhtinian Circle theories to foreign language teaching and learning (HALL et al., 2005), as far as the first years of formal education in Brazil are concerned. Up to the present moment, foreign languages, including English, are not officially part of the National Curriculum of the first five schooling years. Due to the importance of English in a globalized world and despite all the controversial socio-educational impacts of such an influence, there has been an increase in the interest in this discipline at the beginning years of Brazilian public education (ROCHA, 2006), which has been happening at an irregular pace and without official parameters. Therefore, the relevance of this work lies on the possible guidelines it may offer to support a more effective, situated and meaningful teaching-learning process in that context. Standing for a pluralistic approach to language education, we take the bakhtinian speech genres as organizers of the educational process. We strongly believe that through a dialogic, pluralistic and trans/intercultural teaching (MAHER, 2007), whose main objective is the development of multi (COPE e KALANTZIS, 2000) and critical (COMBER, 2006) literacies, the hybridization of genres and cultures, as well as the creation of third spaces (KOSTOGRIZ, 2005; KUMARAVADIVELU, 2008) can happen. From this perspective, foreign language teaching and learning play a transformative role in society and English is seen as a boundary object (STAR e GRIESEMER, 1989), in and by which diversity, pluralism and polyphony can naturally find their way.

Unusual branching in the palm Euterpe edulis Mart

The unusual development of branches along the stem of Euterpe edulis is described for the first time. Branches originated at 2 to 190 cm from the ground. Ramified individuals and branches were able to produce reproductive structures and some branches produced roots. A plausible cause for the observed anomaly could be genetic problems due to small population sizes. The better agreement of this process can have a positive effect in the harvest of the heart of palm through the artificial induction of sprouts, what would prevent the death of the individual.

Antioxidative responses of cell suspension cultures of two Coffea arabica varieties to low aluminum levels at pH 5.8

The effects of aluminum (Al) on the activities of antioxidant enzymes and ferritin expression were studied in cell suspension cultures of two varieties of Coffea arabica, Mundo Novo and Icatu, in medium with pH at 5.8. The cells were incubated with 300 µM Al3+, and the Al speciation as Al3+ was 1.45% of the mole fraction. The activities of superoxide dismutase (SOD), catalase (CAT), and glutathione S-transferase (GST) were increased in Mundo Novo, whereas glutathione reductase (GR) and guaiacol peroxidase (GPOX) activities remained unchanged. SOD, GR, and GST activities were increased in Icatu, while CAT activity was not changed, and GPOX activity decreased. The expression of two ferritin genes (CaFer1 and CaFer2) were analyzed by Real-Time PCR. Al caused a downregulation of CaFER1 expression and no changes of CaFER2 expression in both varieties. The Western blot showed no alteration in ferritin protein levels in Mundo Novo and a decrease in Icatu. The differential enzymes responses indicate that the response to Al is variety-dependent.
