Question

Rocky and Adam exercised on treadmills at equivalent workloads of 6.4 mph at a 0% grade. After 5 min. of jogging at this intensity, Rocky's relative VO2 was 29 mlsO2/kg min, and Adam's relative VO2 was 22 mlsO2/kg min. Who displayed a better movement economy during this bout of exercise? A. Adam B. Rocky C. They had equivalent movement economies D.

Explanation / Answer

the grade is 0% that is Rockey and Adam are running on a flat surface.

There is a negative correlation between VO2 and the energy cost of running (i.e. with increased fitness, or VO2, one will burn less calories to run a given distance).

So higher the VO2 better would be the movement economy.

Between Rockey and Adam , Rockey's relative VO2 is = 29 mls O2 / kg min

and this is more than that of Adam's 22 mls O2 / kg min

=> option B is correct as Rockey's fitness level is more than Adam's.
