Resumen
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
