Components of Energy Expenditure Flashcards
is the measure of energy needed by the body at rest
Basal Metabolism
Formula of Basal Metabolism
1 kcal/ body weight/ hr
1 x ____ weight x hr
What are the conditions of basal metabolic rate (BMR)
-done at least 12 hr after the client’s last meal
- client must be relaxed and free from tension
- keep the temperature at 20-25 C
What are the six ways to calculate the BMR?
- rule of thumb
- harris-benedict method
- biologic body weight raise to the power of
- WHO/FAO/UNU method
- Miffin- St. Jeor Equation
- Oxford Equation
For RTM, use formula ______ for an adult male
______ for an adult female
1 kcal/kg/hr - adult male
0.9 kcal/kg/hr - adult female
Harris Benedict Formula
Male REE= 66.5 + [13.7 x wt (kg)] + [ 5 x ht (cm)] - [6.8 x age (yr)]
Female REE= 665 + [9.6 x wt (kg)] + [ 1.8 x ht (cm)] - [4.7 x age (yr)]
Biologic body weight raised to the 3/4 power
weight ^ 3/4 = metabolic body size
metabolic body size x 70 (constant number) = ______
WHO/ FAO/UNU method
1.6 x wt (kg) + 879 = REE
Mifflin - St. Jeor Equation
Male REE = [9.99 x actual wt (kg)] + [6.25 x height (cm) ] - [4.92 x age (yrs)] +5
Female REE = [9.99 x actual wt (kg)] + [6.25 x height (cm) ] - [4.92 x age (yrs)] - 161
Oxford Equations
Age 18-30 yrs old
Male = (16 x kg) + 545
Female = (13.1 x kg) + 558
Oxford Equation
30-60 yrs. old
Male= (14.2 x kg) + 593
Female = (9.74 x kg) + 694
Oxford Equation 60-69 yrs old.
Male = (13 x kg) + 567
Female = (10.2 x kg) + 572
Oxford Equation
70 yrs old.
Male= (13.7 x kg) + 481
Female =(10 x kg) + 577
Computation of Desirable Body Weight can be measured through
Ador Dionisio’s Method
Tannhauser’s Method
Ador Dionisio’s Method
Height = 5 ft
Men= 110 lbs.
Female = 100 lbs
For any additional inches multiple by 2 then add to lbs.
