Q
  • the measure of energy needed by the body
    at rest for all its internal chemical activities;
    approximately 1 cal per kilo of body weight per hour
    for an adult.
  • It is the min. amount of energy needed by the
    body at rest in the fasting state.
  • Also indicates the amount of energy needed to
    suction the life processes: respiration, cellular
    metabolism, circulation, glandular activity, and
    the maintenance of body temp.

REQUIRED ENERGY EXPENDITURE

14
Q

the metabolic rate is highest during the periods of
rapid growth, chiefly during the first and second years, and
reaches a lesser peak through the ages of puberty and
adolescence in both sexes.

Q

8 FACTORS THAT AFFECT BMR

A
  1. SURFACE AREA
  2. SEX
  3. AGE
  4. BODY COMPOSITION
  5. STATE OF NUTRITION
  6. SLEEP
  7. ENDOCRINE GLANDS
  8. FEVER

Q

use the rule of thumb
1 kcal per kg per hour for adult male
0.9 kcal per kg per hour for adult female

A

CALCULATION OF BMR

14
Q

(1909), uses
information on weight, height, age and sex.

A

Harris-Benedict Formula (1909),

14
Q

3 CONDITIONS NECESSARY FOR BMR Test

A
  1. Fasting or post-absorptive state, at least 12
    hours and no meal.
  2. Must be awake, lying quietly, and free from
    physical fatigue, nervousness, or tension
  3. Environmental temp. should be between 20°𝐶 -
    25°𝐶
14
Q
  • the greater the body surface or skin area,
    the greater the amount of heat loss, and, in turn, the
    greater the necessary heat produced by the body. Muscle
    tissue requires more oxygen than adipose tissue.
14
Q

secrete hormones into the
bloodstream, are the principal regulators of the metabolic
rate.

A

ENDOCRINE GLANDS

14
2 COMPUTATION OF DBW
1. ADOR DIONISIO'S METHOD 2. TANNHAUSER'S METHOD
14
women, in general, have metabolism about 5% to 10% less than that of men even when they are the same weight and height.
SEX
14
a large proportion of inactive adipose tissue lowers the BMR.
BODY COMPOSITION
14
a decrease in the mass of active tissue such as in the case of undernourishment or starvation causes a lowered metabolism often as much as 50% below normal.

FORMULA FOR BMR
HARRIS-BENEDICT FORMULA
14
- metabolic rate falls approximately to 15% below that of waking levels.
SLEEP
14
- it increases the BMR about 7% for each degree rise in the body temp. about 98.6℉
