Question

What is the oxygen requirement (VO_2 ml kg^-1 min^-1) for running a 10K race (i.e., 10000 meters) on a track in 48 minutes? Determine the approximate work rate (in Mets) for running on a treadmill at a speed of 5.0 mph and a 4% grade elevation. What is the total caloric cost (kcal) for 190 lb man exercising for 30 minutes at this workrate?

Answer 1

question 5

10000 m / 48 min=208.33m / s

VO2 (mL . kg-1 . min-1) = (0.2 ml/kg. min) (horizontal velocity ) + 3.5 mL. kg-1.min-1

Vo2 =208.33m / s * ml/kg. min + 3.5 mL. kg-1.min-1

=45.166 ml. kg^-1 .min^-1-----------------answer
