Abstract

The purpose of this study was to describe the relationships between RE and the neuromechanics of ground contact. Results of biomechanical studies suggest that more economical runners use different neuromuscular strategies during the stance phase of running. Research in our lab revealed significant, positive correlations between metabolic cost and positive work at the hip and ankle, but significant, negative correlations between metabolic cost and positive work at the knee. Studies focusing on RE and muscle activation patterns show contrasting results. Mechanics may suggest straightforward applications to training and coaching, but further study is required in the area of muscle activation.
