Should Distance Runners Do Speed Workouts?

There are plenty of factors that have been identified to contribute to improving running economy, both physiological and biomechanical. Not all of them can be improved by sprint training, but some of them certainly can. One of the key kinematic variables related to running economy is a low vertical oscillation of body center of mass. One way to prevent this vertical oscillation is to ensure that the support leg does not buckle on ground contact, and instead can maintain center of mass height throughout the stance phase.
