The Real Paradox of the Extensor Paradox

Considering the running motion, we already know that maximum quadriceps muscle activity occurs at the transition between knee flexion and extension and coincides with maximum vertical ground reaction force. After this, knee extensor muscle activity starts to diminish and ends almost entirely just as leg extension begins. So as the leg is rapidly extending, the… Read more

The Extensor Paradox in running

The original article below on the topic at hand, was published in Biomechanics of Distance Running in 1990. As you read the data and conclusions from this research you’ll see that the running  scientific community was not ready to accept the idea of the role of gravity as a leading force in running. A classical… Read more
