Muscle effect on burst characteristics for young adults. (a) Number of bursts; (b) burst percentage; (c) mean burst duration; (d) peak burst amplitude. BB: biceps brachii; TB: triceps brachii; VL: vastus lateralis; BF: biceps femoris; sec: seconds; %: percentage; MVE: maximal voluntary exertion. aSignificantly different from BB; bsignificantly different from TB; csignificantly different from VL.
