EMG amplitude and frequency parameters of muscular activity: Effect of resistance training based on electromyographic fatigue threshold
(Elsevier B.V., 2009-04-01)
The present study aimed to evaluate the effect of a resistance training program based on the electromyographic fatigue threshold (EMG(FT), defined is the highest exercise intensity performed without EMG alterations), on ...
Back extensor muscle fatigue at submaximal workloads assessed using frequency banding of the electromyographic signal
(Elsevier B.V., 2011-12-01)
Background: Changes in the mean or median frequency of the electromyographic (EMG) power spectrum are often used to assess skeletal muscle fatigue. A more global analysis of the spectral changes using frequency banding may ...
Functional and morphometric differences between the early and delayed use of phototherapy in crushed median nerves of rats
(SPRINGER LONDON LTDLONDON, 2012)
This study evaluated the functional and quantitative differences between the early and delayed use of phototherapy in crushed median nerves. After a crush injury, low-level laser therapy (GaAs) was applied transcutaneously ...
Polymorphisms in the RAC1 Gene Are Associated With Hypertension Risk Factors in a Chilean Pediatric Population
(OXFORD UNIV PRESS, 2014)
The GTPase Rac1 has been implicated in hypertension as a modulator of mineralocorticoid receptor activity. Our aim is to investigate the frequency of polymorphisms rs10951982 (intron 1, G > A) and rs836478 (intron 3, T > ...
An interconnected type-1 fuzzy algorithm for impulsive noise cancellation in multicarrier-based power line communication systems

The compulsive-like aspect of the head dipping emission in rats with chronic electrolytic lesion in the area of the median raphe nucleus
(Associação Brasileira de Divulgação Científica (ABRADIC), 2004-02-01)
Head dipping (HD) is a behavioral pattern considered to have a risk assessment or an exploratory role and is used as a complementary parameter to evaluate anxiety in experimental animals. Since rats with electrolytic lesion ...
Test-retest reliability of electromyographic variables of masseter and temporal muscles in patients with cerebral palsy
(Elsevier B.V., 2014-12-01)
Introduction: The aim of this study was to evaluate the reliability of surface electromyography of the masticatory muscles in patients with cerebral palsy.Methods: Surface electromyography was performed over the masseter ...
Analysis of localized muscle fatigue in elderly women with and without a history of falls using electromyographic signal frequency parameters
(Universidade Federal de Santa Catarina, 2014-07-01)
One of the problems that most concerns the elderly population is the falling, which can be caused by muscle fatigue. The objective of this study was to compare median electromyographic frequency values for the vastus ...
