Groucho running reveals disparate results between ground reaction force and tibia-fibula bone strain in runners

The relationship between external forces and bone strain in running is often complex and nonintuitive.

The relationship between external forces and bone strain in running is often complex and nonintuitive. We used Groucho running (i.e., running with exaggerated knee flexion) as a model to dramatically reduce the vertical ground reaction force (VGRF) and examined the relationship…
