Introduction: economy of running: a multidisciplinary perspective.

This symposium endeavors to address the issue of running economy from a multidisciplinary perspective. Topics addressed in this symposium include physiological aspects of running economy, changes in running economy with age during childhood and adolescence, biomechanical considerations for economical walking and running, psychological state and running economy, and running economy of elite performers. While the knowledge base in this area is expanding, future research should emphasize the formulation of testable hypotheses and the fostering of collaborative efforts aimed at identifying and manipulating variables associated with improved economy and discovering mechanisms underlying economical running styles.
