ELECTROMYOGR CLIN NEUROPHYSIOL , 2003, vol. 43, n° 3, p. 131-140 Doc n°: 108356 Localisation : Documentation IRR Descripteurs : AK2 - EMG , DD22 - EXPLORATION EXAMENS BILANS - CEINTURE SCAPULAIRE The muscles deltoid-anterior portion (DA) and pectoralis major-clavicular portion (PMC) were analysed to establish the muscular behavior and intensity patterns, as well to evaluate the connected participation of these muscles during supine and frontal elevation exercises. Twenty-four male volunteers were examined using a 2-channel TECA TE4 electromyograph and Hewlett Packard surface electrodes. Our results showed low levels of activity to PMC in frontal elevation exercises, whereas to DA the levels were very high. In the supine exercise, the action potential levels developed by the PMC were always lower than those presented by DA, however, with action simultaneity. Some suggestions to the use of the tested exercises are presented. Langue : ANGLAIS Tiré à part : OUI Identifiant basis : 2003226447 |
