Hello,
Could anyone help me understand the explanation of this Korean documentary about running technique at 6:23 ? When they talk about the calves (48%? 81%?) ? What does these percentages correspond to ? Thks.
Looks like its about efficiency. It basically says that because of his running style, the first guy (Makau) puts less impact on his feet when they strike the ground, so he saves energy and only uses about 48% of his maximal muscular output in his calves; the second guy has to use 81% because he’s running less efficiently.
