Mennyit számít a cipő súlya?

(nem sokat, szerinte...)

"[...]We found adding 100 grams to the shoe increased the aerobic demand of running by 1%. Now 100 grams is about 3.5274 ounces, so each ounce changes the cost of running about 0.2835% (1/3.5274= 0.2835). If you can run a mile in 5:40, that is going 284 meters per minute and that speed of running typically coasts about 55.55 ml O2 per Kg body weight per minute.  1 less ounce will change the cost to about 55.7075 (from 55.55 above) and that VO2 will be associated with a running speed of 284.7 m/min and a mile time of 5:39.17, so about .83 seconds for a mile, per ounce less weight.[...]"
