RUNNING ECONOMY AND MECHANICS IN TRIATHLETES vs. RUNNERS

The purpose of this study was to compare running economy (RE) and distance running mechanics between triathletes and runners to examine an energy-economical running form. Physiological measures were obtained, including maximal and submaximal 02 consumptions and blood lactate concentration. Biomechanical measures for running at several speeds (210-290 mlmin) were obtained for the triathletes and runners. The RE in the triathletes was higher than that in the runners at most speeds (210-270 mlmin). The maximal angle of shoulder extension was associated with RE and greater in the triathletes at lower speeds (21 0-250 mlmin). The training and running form of triathletes are potentially useful for improving the RE in runners
