Metabolic Equations Examples Resting Energy Component (R) Horizontal Energy Component (H) Vertical Energy Component (V) Resting Energy Component (R) ALWAYS 3.5 ml/kg/min (1 MET) *must convert relative VO2 (ml/kg/min) to absolute VO2 (ml/min) when using equations for cycle ergometer Horizontal Energy Component (H) WALKING 0.1 ml/kg/meter speed in meters/minute (m/min) = RUNNING 0.2 ml/kg/meter speed in m/min=. ml/kg/min CYCLE=0.0 * • Total Energy (VO₂) = R + H+V Vertical Energy Component (V) WALKING = 1.8 ml/kg/meter speed in m/min* % grade - = RUNNING 0.9 ml/kg/meter speed in m/min* % grade= CYCLE 2.0 ml/kpm power in kpm/min ml/min Make sure that %grade is in decimal form, for example 5% grade should be 0.05 in equations. = m/min ml/kg/min ml/kg/min ml/kg/min kpm/min-resistance (kp)* pedal speed (m/min) To calculate speed in m/min, remember that 1 revolution of a Monark Bike covers 6 meters x rev/min 6 m/rev=
1. Meredith is walking on a treadmill at 0% grade. Given that her VO2 is 0.52 L/min and her weight is 65 kg, find speed in m/min and in mph. 2. Determine George's percent grade if his VO2 is 14 ml/kg/min and speed is 78 m/min 3. Derek is on a treadmill that is set at a speed of 54 m/min at 5% grade. Determine vertical VO2 and total VO2 (relative) 4. Christina (57 kg) is walking at a speed of 3.9 mph on a level surface. Find her total relative and absolute VO2. 5. Izzie's vertical VO2 is 14.47 ml/kg/min and speed is 268 m/min. Find percent grade. 6. Alex's (81 kg) speed is 118 m/min at 0% grade. What is his total relative and absolute VO2? 7. If a cycle ergometer is set at 2.5 kp and Dwight's power is 150 Watts, how fast is he pedaling? 8. What is the power output if Michael weighs 76 kg and has a VO2 of 46 ml/kg/min on a cycle ergometer? 9. If Pam weighs 61 kg and her VO2 is 1850 ml/min, what is her power output on a cycle ergometer? 10. Determine Jim's total VO2 in relative terms if he weighs 82 kg and is cycling against 2 kp of resistance at a speed of 54 rpm. 11. Jan weighs 58 kg and is riding a cycle at 200 Watts. Find her energy expenditure in kcal/min. 12. Stanley's (102kg) VO2 is 22 ml/kg/min while pedaling against 2.5 kp's. How fast is he pedaling in rpm's? 13. Phyllis (86kg) walks at 3.2 mph and 0% grade. What is the MET level of her activity? 14. Andy decides to "jog off" his anger. If his VO2 is 32 ml/kg/min and he is running on a - flat track, how fast is he going in mph? 15. If a treadmill belt is 141 inches long and travels 10 revolutions in 46 seconds, how fast is the belt speed in m/min? 5
