Abstract :
The myoelectric responses from 156 electrically stimulated contractions in two different lumbar muscles were examined. A method for assessing the invariance of the motor unit pool during the contraction was applied, and fatigue was evaluated. The assumption that fast-fatiguing glycolitic fibers have larger diameters than slow-fatiguing oxidative fibers is not always able to explain the results. It is suggested that this assumption may not always be true in lumbar muscles
