Metabolic Calculations Practice Key Walking VO2 (ml/Kg/min) = (0.1 x speed (meters per minute)) + (1.8 x speed x grade) + 3.5 Running VO2 (ml/Kg/min) = (0.2 x speed (meters per minute)) + (0.9 x speed x grade) + 3.5 Bike VO2 (ml/Kg/min) = ((1.8 x Kgm/min) ÷ body mass) + 7 = ((10.8 x Watts) ÷ body mass) + 7 Stepping VO2 (ml/Kg/min) = (0.2 x step frequency) + (1.33 x 1.8 x step height x step frequency) + 3.5 (step height in meters, frequency in steps per minute) Given: 1 mph = 26.8 m/min 1 inch = 0.0254 meters 1kg = 2.2 lbs 1 watt = 6.12 Kgm/min l/min = (ml/kg/min x BM)/1000 Memorize: 1 MET = 3.5 ml/Kg/min of oxygen

1.

Cathy, a 190 pound female, circuit trains for 60 minutes. During the workout, she works at a level of 4 METS. Given this information, determine how many kcals Cathy burns during the 60 minute workout (starting with determining her relative VO2 based on her MET level) 14 ml/kg/min = 4METS x 3.5ml/kg/min (14ml/kg/min x 86.4kg) / 1000 = 1.2 L/min 1.2 L/min x 60 min = 72 LO2 72 LO2 x 5kcal = 360 kcal

A) Katy (weight 130 lbs) steps onto a 12 inch box at a rate of 32 steps/minute. What is Katy’s relative VO2? B) During the workout, at what MET level will Katy be exercising? a) VO2 = (.2 x 32) + (1.33 x 1.8 x .304 x 32) + 3.5 VO2 = 6.4 + 23.3 + 3.5 VO2 = 33.2ml/kg/min b) 33.2ml/kg/min / 3.5ml/kg/min = 9.4 METS

3.

Andy (weight 165 lbs) is cycling at an intensity of 65W for 1 hour. Determine how many kcals Andy burned during his workout. VO2 = ((10.8 x 65) / 75) + 7 (702/75) + 7 9.36 +7 VO2 = 16.36ml/kg/min L/min = (16.36 x 75) / 1000 = 1.23 L/min 1.23 L/min x 60 min x 5 kcal = 368kcal...
