Muscle effect on mean burst duration and peak burst amplitude for old adults. (a) Mean burst duration; (b) 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.
