I saw the video, and yes, I distinctly remember them showing the psoas major muscles across Asafas’ hips as being allmost double the cross-sectional mass of Japan’s top sprinter.
However, ‘Go Fast’ seems to imply that Asafas’ patella tendon also has impressive mass.
Quote from ‘Go-fast’;
“The Japanese docu observation of Asafa’s massive patella tendon could be coming from the hill runs and sled work.” (un-quote)
That’s why I am asking him for clarification that he meant as he implied.
As a side note question Robin, would you say that hills can increase the stiffness of patella tendon compared to the track?
And is it stiffness or compliance that we want from this tendon?, as we have heard opposing theories on these matters.
