Previous issue date: 2013-02-28 / The fluctuacion force has been increasingly used in studies with elderly as a
good predictor of performance and functionality of the motor. 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
