The Saga of 2 Runners has been in the Bearpowered resource area for a good period of time. The video, from Ken Jakalski, shows 2 athletes running past a set of cones placed 1 meter apart. The cones were used as a reference marker for his diagnostic software.

Ken sandwiched the videos together (which explains why there are 2 sets of cones, but the distance between matching pairs is the same) to highlight some very interesting but overlooked aspects of mass-specific force.

We’ve used software to highlight some of the more important aspects of what is described in Weyand and Sternlight’s ground breaking 2000 JAP study.
