Then last night I read the following story about a running shoe that shaves 4% off of running times:
"Embedded in the length of the midsole is a thin, stiff carbon-fiber plate that is scooped like a spoon... The plate is designed to reduce the amount of oxygen needed to run at a fast pace. It stores and releases energy with each stride and is meant to act as a kind of slingshot, or catapult, to propel runners forward."For athletes, who can carbo-load, it's not food that is the limiting factor in performance, it's the VO2-max - how much oxygen they can take in and get to the cells that need it. And so - here, in an article on running - we see them talk about energy as linked to oxygen. It's not as explicit as "food has calories." - they don't directly say "the energy stored in the shoe means you don't need to bring in energy from oxygen...." but it's as close as I've seen.
😊
Also, I immediately wanted to energy theater that shoe, and compare it to an energy theater of a normal shoe.
