That is a strange way to look at things.
So because one part of this guys leg isn't prone to the same type of muscle fatigue, you would reason that this gives him and unfair advantage?
I have to say, in all my years of running I've never thought or felt:
"Damn!! If only the portion of my leg below my knees could stay springy, I could run faster for longer".
What about the other parts of my body that have fatigued? Don't they then become the "bottlenecks" to performance (as if premature fatiguing of the portion of my leg below my knee was EVER the bottleneck to anyone's performance)?
