From the men's 1500 qualifying heat video recorded at the NCAA Div 1 regional meet in Eugene, we examine (using the Kinematic Running Assessment Method, KRAM) specific factors affecting running efficiency and performance. Contact Us to find out more about Y-axis Training. The Kinematic Running Assessment Method uses Dartfish software;

The key factors in this analysis are: (a) Introducing the "angle of foot-strike" as an indicant of hamstring timing (in male runners), (b) its effect on "knee-compliance" and (c) how knee -compliance causes excess ground-contact and oxygen consumption (according to Cavanagh, 1990, it costs 25% more oxygen consumption for every 5 degrees of additional knee-collapse during the stance phase of running at the same pace). For comparison, check out Galen Rupp's KRAM scores.

Extra: Examine how Galen Rupp's motor behaivor yields low lactate, permitting a dominating end-race. Also find out how vertical ground forces benefit forward momentum; why is vertical ground contact better than a powerfull backward push-off?
