Calculating Energy Expenditure Equations

Question 1

Rest Metabolism

Answer 1

1 MET= 3.5 ml.kg.min

Question 2

conversion of METs to VO2

Answer 2

MET level x 3.5

example: 6 METs represents

6 x 3.5= 21 ml.kg.min

Question 3

From Vo2 to METs

Answer 3

VO2 / 3.5
Example

23 ml.kg.min /3.5 = 6 METS

Question 4

When calculating energy expenditure always use

Answer 4

NET VO2 or NET METs

Question 5

USING Vo2 MAX

A 115 lb individual running 6.0mph
0% grade
30 mins
This is equivalent to 34.3 ml.kg.min(Vo2)

how man Kcal are being burned ?

What are the steps

Answer 5

EQUATION:
Vo2 x kg x 5 kcal/ 1000

1. convert lbs to kg
   115/2.2=52.27 kg
2. plug in the numbers for the equation
3. 3 x 52.27 x 5/ 1000= 8.98 kcal/min

for 30 mins :

8.98 x 30 min = 268.8 kcal

Question 6

USING METs

Answer 6

A 115 lb. individual running 6.0 mph 0% grade for 30 min. This is equivalent to 9.8 METs

{ MET value x 3.5 } x weight in Kg ÷200

{ 9.8 x 3.5 } x 52.27 ÷200 = 8.96 kcal. Min

8.96 kcal.min x 30 min = 268.8 kcal

Question 7

Walking Equations

Answer 7

Target Vo2 (in ml.kg-1 . min-1)=(0.1 x s) + (1.8 x s x grade) + 3.5

Target V02= (0.1 x s) + (1.8 x s x g) + 3.5

Question 8

Running Equations

Answer 8

Target VO2 = (0.2 . S) + (0.9 . S . G) + 3.5

Target VO2 (mL . kg-1 . min-1) = (0.2 . S) + (0.9 . S . G) + 3.5 mL. kg-1.min-1
