INTERACTIONS BETWEEN THE ANTERIOR ABDOMINAL WALL MUSCULATURE OF ATHLETES

Abstract

The location of a muscle's origin and insertion, joint structure and the joint actions of the surrounding musculature are important factors to consider when evaluating the role of a muscle in human movement. An equally important concept is that the contraction of a muscle produces an equal force at both ends of the muscle. However, the previous statement is true only in cases where the muscle in question does not have an anatomical landmark between its ends which might be capable of transmitting forces to objects external to that muscle.
