Stewart has a BMR of 160. kJ/d and climbs to the 13th floor of his office building in 4.00 min while consuming only 0.0100 kg of carbohydrate having an energy content of 17.2 MJ/kg. The distance between the floors is 7.60 m. What is Stewart's energy conversion efficiency if he does not lose any weight during the climb?
Note: Stewart must supply energy to achieve his kinetic energy motion, but this energy is not recovered when he stops.
