Alternating Muscle Activation Patterns Across The Deltoid Muscles During Sustained Fatiguing Contractions, Ningzhen Zhao, Xin Yu, Lisa Griffin

International Journal of Exercise Science: Conference Proceedings

Alternating muscle activation (AMA) across synergists has been identified in lower-extremity muscles that may function to prolong force output during sustained contractions; however, this has not yet been identified in upper extremity muscles. AMA consists of two periods: co-activation (Co-A), in which a pair of synergists are simultaneously increasing or decreasing EMG amplitude, and trade-off (TO), in which the EMG amplitude of one muscle is increasing while the EMG amplitude of a synergist is decreasing. We hypothesized that TO duration would increase and Co-A duration would decrease during fatigue. PURPOSE: To investigate AMA patterns during sustained submaximal isometric fatiguing …
