Between individuals faster sprinting speeds are achieved by applying greater stance average forces against the running surface. Recent evidence further indicates that elite level performers also strike the ground with leg kinematics that differ from those of non-elites and that these leg movements act to enhance the force transients occurring in the milliseconds following foot-ground impact. I investigated whether sprint performance could be enhanced through a short term gait intervention, consisting of 3 laboratory training sessions wherein subjects (n = 6) completed 5 high-speed runs on an instrumented force treadmill at 90% of their measured top sprint. The subjects received …

The delivery of oxygen to working muscle in order to support aerobic respiration has long been recognized as one of the critical elements conferring endurance performance. Oxygen is transported from the environment to the active cells by the cardiovascular system, which is classically understood to deliver progressively greater amounts of gas to support increased levels of aerobic metabolism. However, the vast majority of existing studies have used modes of exercise that activate relatively small volumes of muscle and consequently have relatively small demands for oxygen delivery. We measured …
