basal metabolic rate (BMR)
the minimum amount of energy the body requires to carry on all vital functions
true or false: BMR varies throughout the lifecycle
true or false: BMR is generally lower at birth and decreases until age 2, after which is increases as life progresses
FALSE: BMR is generally higher at birth and increases until age 2, after which it decreases as life progresses
what are 7 factors affecting BMR?
1) body composition
2) physical fitness
3) gender (males approx. 5% higher)
5) Pregnancy (20% increase)
6) Body temperature
the amount of energy expended through physical activity depends on what 3 things?
1) volume of exercise (time, number of workouts)
2) intensity of exercise
3) type of exercise

3) provides a means of managing stress
4) helps prevent osteoporosis

what is the most common method used in body composition analysis?
the 'Two Component' model of the body
what does the 'Two Component' model of the body include?
- lean body mass (LBM)
- Fat Body Mass
- Total Body fat (TBF)
how is lean body mass calculated?
LBM = TBM - TBF (lean body mass = total body mass minus total body fat)
how is total body fat calculated?
TBF = TBM x %Body Fat/100
what are the 2 divisions of fat body mass?
1) storage fat (SF)
2) Essential Fat (EF)
_______ fat is fat that accumulates as adipose tissue
adipose = ____

9) central nervous system
