However, most analyzes the fluctuation of force in one session. Thus, identifying the minimum amount of sessions needed for familiarization with the fluctuation strength in isometric exercise become relevant. Furthermore, to investigate the effects of applying transcranial direct current stimulation (tDCS) associated with regular exercise on rates fluctuation task force is extremely important. In the first experiment, volunteers were subjected to a protocol marked by a familiarization session to establish the parameters of VCM and eight sessions with intensity of 30% MVC in office. It was observed that two familiarization sessions are required so there is a fluctuation stabilizing force. In experiment II, subjects performed an isometric contraction before and after applying tDCS (cathode, anode and sham) applied to M1. ETCC anodic effectively contributed to reducing the fluctuation of force during isometric exercise in the elderly, while the cathodic caused the increased levels of strength fluctuation. It was concluded that there is a need to implement a familiarization protocol with at least two sessions to avoid possible misunderstandings of measurements in tests of fluctuacion force. Besides that tDCS interfered with the behavior of the oscillations of force, with cathodic promoting increased fluctuation strength and anodic contributed to greater stability, demonstrating the potential of this technique neuromodulation associated with exercise as rehabilitation tools / A flutua??o de for?a tem sido cada vez mais utilizada em estudos com idosos como um bom preditor de desempenho e funcionalidade da motricidade. No entanto, a maioria analisa a flutua??o de for?a em sess?o ?nica. Assim, identificar a quantidade de sess?es m?nimas necess?rias para a familiariza??o ao teste de flutua??o de for?a em exerc?cio isom?trico tornar-se pertinente. Al?m disso, investigar os efeitos da aplica??o da Estimula??o Transcraniana por Corrente Cont?nua (ETCC) associada ? pr?tica regular de exerc?cio sobre os ?ndices de flutua??o de for?a ? tarefa de extrema relev?ncia. No experimento I, volunt?rias foram submetidas a um protocolo de familiariza??o marcado por uma sess?o para estabelecer os par?metros de CVM e oito sess?es com intensidade de 30%CVM em exerc?cio. Observou-se que duas sess?es de familiariza??o s?o necess?rias para que haja uma estabiliza??o da flutua??o de for?a. No experimento II, volunt?rias realizaram uma contra??o isom?trica antes e ap?s a aplica??o de ETCC (cat?dica, an?dica e sham) aplicada ao M1. ETCC an?dica contribuiu efetivamente para a redu??o da flutua??o de for?a em idosos durante exerc?cio isom?trico, enquanto que a cat?dica provocou o aumento dos ?ndices de flutua??o de for?a. Concluiu-se que h? a necessidade de aplica??o de um protocolo de familiariza??o com pelo menos duas sess?es para que sejam evitados equ?vocos de mensura??es em testes de avalia??o da flutua??o de for?a. Al?m de que a ETCC interferiu no comportamento das oscila??es de for?a, com cat?dica promovendo aumento da flutua??o de for?a e a an?dica contribuiu para uma maior estabilidade, demonstrando o potencial dessa t?cnica de neuromodula??o associada ao exerc?cio como ferramentas de reabilita??o

In a complementary manner, it intends also to evaluate if the own latin american history represents an incentive to researchers of different knowledge's areas get help in the Agamben's teachings, in reason to a convergency of theories (Homo Sacer, State of Exception, bare life, biopolitic, camp, etc) and facts (colonization, dictatorial regimes, violence state, etc.). At the end, original manners to enrich reasonings and debates about important social political problems will also be evaluated, using, for that, concepts developed by Giorgio Agamben, writer that, necessary to register, owns a theoretical framework rich, dense, sometimes complex, but, first off all, quite appropriate to face actual questions related to the natural tension between the State and the Individual and, therefore, related to the own life. / A proposta inicial desta dissertação concentra-se, principalmente, na procura de indicativos de que a obra do escritor italiano Giorgio Agamben influencie de maneira significativa a literatura político acadêmica produzida na América Latina. De modo complementar, pretendese avaliar também se a própria história latino americana representa um incentivo para que pesquisadores de diferentes áreas do conhecimento recorram aos ensinamentos de Agamben em razão de uma convergência entre teorias (Homo Sacer, estado de exceção, vida nua, biopolítica, campo, etc) e fatos (colonização, regimes ditatoriais, violência estatal, etc). Por fim, serão avaliadas também maneiras originais de enriquecimento de raciocínios e debates elaborados sobre importantes problemas sociopolíticos, utilizando, para tanto, conceitos desenvolvidos por Giorgio Agamben, autor que, necessário registrar, possui um arcabouço teórico rico, denso, algumas vezes complexo, mas, acima de tudo, sobremodo apropriado para o enfrentamento de questões atuais e relacionadas à tensão natural entre o Estado e o indivíduo e, portanto, à própria vida.
