Question

Estimate how much faster a 75 kg man can run a mile with blood doping. If we assume he could run a 4 minute mile before blood doping, how much faster will he be after blood doping? Is this a significant decrease in time? Show all calculations and list any assumptions in solving for your answer.

Useful facts:

One liter of oxygen generates 4.82 kcal (20.17 kJ).

A joule is a unit of energy or the work done in moving a force times a distance (Joule = N-m).

Recall that power = rate of doing work = joules/sec=watt.

1 Joule = 0.239 calories
