Eficácia do treinamento de força sobre parâmetros cardiovasculares e antropométricos em adultos sedentários

This study aimed to determine the influence of strength training (ST), in three weekly sessions over ten weeks, on cardiovascular parameters and anthropometric measurements. It is a before and after intervention trial, with a sample composed of 30 individuals. Participants were adults aged between 18 and 40 years, from both sexes and sedentary for at least three months previously. Tests were computed ergospirometry, CRP, PWV and body composition (dependent variables) before and after the experiment. Independent variables, age and sex, were considered in order to determine their influence on the dependent variablesevaluatedend. By comparing the initial cardiovascular parameters with those obtained after intervention in patients undergoing the ST proposed (a Student s t-test was conducted within each group for samples matched to parameters with normal distribution, while the Wilcoxin was applied for those without), there was no significant difference in PWV(p =0469) or PCR(p =0.247), but there was an increase in anaerobic threshold(AT) (p=0.004) and Maximal Oxygen Uptake(VO2max) (p =0.052). In regard to anthropometric measures, individuals significantly reduced their body fat percentage (p<0.001) and fat mass (p<0,001), as well as increasing lean mass (p<0.001). However, no changes were recorded in the waist-to-hip ratio (WHR) (p= 0.777), body mass (p=0.226) or body mass index (BMI) (p =0.212). Findings of this study lead us to believe that the proposed ST, and did not increase the VOP or PCR improves cardiorespiratory capacity and body composition. Devotees of this training can therefore safely enjoy all its benefits without risk to the cardiovascular system

Rituais de resistência: experiências pedagógicas tapeba

The work aims to investigate some of the educational actions developed in the differentiated Tapeba schools (CE), in their pedagogical practices. The reading of these practices as ritual of ethnic cultural resistance is accomplished by the approach of studies of experience and performance in the anthropology, as well as, the analytical perspective suggested by the dramaturgy ideas and social drama. So, taking a critical approach of the school, that conceives it, while time space privileged of possibilities of political social change, this work searches to notice the means of achievement of a differentiated education. I aim at, with that, to observe the ritual moments and performáticos of the pedagogic practices of Tapeba while important political-symbolic expressions of your collective experiences, looking at the process of construction of legitimacy of the school differentiated as scenery of creation of pedagogic rituals of resistance. Then, the Cultural Fair, Tapeba Indian Games, the Walking of Tapeba Indian`s Day and Carnauba Party by one side and the Cultural Classes, by another, promote a re-thinking on the experiences of Tapeba ethnicity, distinguishing also, in this process of identity affirmation, the political pedagogical role fulfilled by land re-taking. Finally, this work makes clear that Tapeba prove to be individuals with rights and at the same time they want to legitimate their differentiated school practices, Tapeba construct the meaning of their social actions in the educative and in other aspects of their communitarian living as well
