1

more than __% of Canadian adults are considered overweight or obese

35%

2

more than __% of Canadian children are considered overweight or obese

30%

3

weight stability

calories consumed = calories expended

4

weight gain

calories consumed > calories expended

5

weight loss

calories consumed < calories expended

6

basal metabolic rate (BMR)

the minimum amount of energy the body requires to carry on all vital functions

7

true or false: BMR varies throughout the lifecycle

true

8

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

9

what are 7 factors affecting BMR?

1) body composition
2) physical fitness
3) gender (males approx. 5% higher)
4) Sleep
5) Pregnancy (20% increase)
6) Body temperature
7) age

10

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

11

in order to efficiently lose weight what should exercise be combined with?

controlled eating patterns that involve calorie reduction

12

what are 6 benefits of exercise?

1) strengthens the heart
2) improves endurance
3) provides a means of managing stress
4) helps prevent osteoporosis
5) burns calories
6) increases metabolic rate

13

what is the most common method used in body composition analysis?

the 'Two Component' model of the body

14

what does the 'Two Component' model of the body include?

- lean body mass (LBM)
- Fat Body Mass
- Total Body fat (TBF)

15

how is lean body mass calculated?

LBM = TBM - TBF (lean body mass = total body mass minus total body fat)

16

how is total body fat calculated?

TBF = TBM x %Body Fat/100

17

what are the 2 divisions of fat body mass?

1) storage fat (SF)
2) Essential Fat (EF)

15%

25

true

26

______ fat is required for normal physiological functioning

essential fat

27

list 9 places essential fat is present

1) bone marrow
2) heart
3) lungs
4) liver
5) spleen
6) kidneys
7) intestines
8) muscle
9) central nervous system

12%

30

true or false: storage fat is gender specific

false: essential fat is gender specific
