1

4 factors that determine fitness:

1. Body composition
2. Muscular strength
3. Aerobic Endurance
4. Muscle Flexibility

2

2 factors that contribute to Body Composition:

1. Lean body mass
2. Body Fat

3

Lean body mass consists of:

- muscle
- bones
- organs
- skin
- NOT fat

4

What are the 2 Type of fat?

1. Storage fat
2. Essential fat

5

Name 4 functions of Essential Fat:

1. Thermoregulation
2. Cushioning
3. Protection
4. Source of energy

6

Fat cells are called? SPELL IT!

Adipocytes

7

Adipocytes increase and decrease in size with _____________.

Weight loss and weight gain.

8

Cell number is constant but volume can change. What kind of cells does this describe?

Adipocyte cells

9

What are 3 methods used to determine % body fat composition:

1. Body measurements
2. Skinfold measurement
3. Electrical Impedance

10

BMI stands for what? List the 2 measurements that it DOES take into account:

Body Mass Index
1. Hight
2. Weight

11

What type of fat does skinfold measurement measure?

Subcutaneous fat

12

What are the 3 skin fold measurements for men:

1. Chest
2. Abdomen
3. Thigh

13

What are the 3 skinfold measurements locations for women:

1. Tricep
2. Suprailium
3. Thigh

14

What is the measurement tool used in skinfold measurements?

Skin caliper

15

Explain in one sentence how "electrical impedance" measures body fat:

Mild electric current is passes through the body, because most body tissue is mostly water it is a good conductor, fat is a bad conductor. Therefore it impedes flow of the current and the amount of imprudence is measures to determine % body fat.

16

How do you increase muscle strength?

- resistance training
- high intensity / short duration

17

How do you increase aerobic endurance?

- aerobic exercise
- less intense / longer duration

18

What is characterized as aerobic activity?

Aerobic activity 20-30min 2-5 days / week

19

What is the calculation for target heart rate?

(220 - age) x .65 = threshold HR
(220 - age) x .85 = max aerobic HR

20

What is the test for muscle flexibility?

Sit & reach

21

List the 4 benefits of cardo-respiratory training:

1. Slower HR due to Inc. stroke volume
2. Reduced BP (heart efficiency is inc. and vascularity is inc.)
3. Increased respiratory volumes
4. VO2 max is Inc. (cells develop inc ability to utilize available O2 in the blood)

22

The energy requirements of each day consist of what 3 factors:

1. Daily physician activity
2. BMR / 24hrs (calories to run basic metabolic body functions)
3. Terminal effect of food (amount of energy used to digest food)
