Mechanomyographic responses to continuous, constant power output cycle ergometry
PERRY SR; HOUSH TJ; JOHNSON GO
ELECTROMYOGR CLIN NEUROPHYSIOL , 2001, vol. 41, n° 3, p. 137-144 Doc n°: 100060 Localisation : Documentation IRR Descripteurs : AK2 - EMG The purpose of the present investigation was to examine the mechanomyographic (MMG) and electromyographic (EMG) response to continuous, constant power output cycle ergometer workbouts. The results indicated dissociation between the patterns of the mechanical (MMG) and electrical (EMG) activity of the vastus lateralis during continuous cycle ergometry at low power outputs. The increases in EMG amplitude were likely due to the recruitment of additional motor units. The decreases in MMG amplitude across time may have been to the phenomenong know as "muscular wisdom" and/or decreases in muscular compliance.
