Focused on physiology of human movement and effects of environmental stress on exercise

Question 6

Surgeon Generals Report 1996

Answer 6

ON PHYSICAL ACTIVITY: 30 mins of moderate activity everyday

Question 7

4.184 Kilojoules (Used in european countries)

1000 Calories

Question 9

1 Kilogram (kg)

Answer 9

2.2lb

Question 10

1 inch

Answer 10

2. 54 cm

0. 0254 m

Question 11

1 Liter

Answer 11

1000 ml

Question 12

Energy Systems

Answer 12

Stored ATP-CP (Immediate) 
Anaerobic Metabolism/Glycolysis (short term)
Aerobic Metabolism (long term)

Question 13

VO2

Answer 13

Volume of oxygen consumed at a given workload. ONLY WHAT HAS BEEN CONSUMED BY LUNGS. Measures aerobic fitness (mlO2/kg/min)

Question 14

Homeostasis

Answer 14

Maintenance of a constant internal environment

Question 15

Steady state

Answer 15

Relates to an unchanging situation. HR is not increasing or decreasing

Question 16

Anaerobic Threshold

Answer 16

Onset of blood lactate accumulation. It is the point at which the extra energy for exercise must come from anaerobic sources and therefore increase blood lactate

Question 17

Oxygen Consumption

Answer 17

Relative

Absolute

Question 18

MET

Answer 18

One MET is equal to the resting metabolic rate of 3.5 ml O2/kg/min.

To get mets from VO2 divide your VO2 by 3.5

Question 19

Skill Components of Fitness

Answer 19

Balance, Coordination, Agility

Question 20

Health Components of Fitness

Answer 20

Cardio Respiratory Fitness
Musculoskeletal Strength 
Musculoskeletal Endurance 
Musculoskeletal Flexibility 
Body Comp

Question 21

Current ACSM/AHA Recommendations

Answer 21

Mod Cardio 30 mins 5 days a week
Vigorously intense Cardio 20 mins a day 3 days a week
8-10 strength training exercise for 8-12 reps 2x a week

Question 22

C.G Douglas

Answer 22

Douglas Bag

Question 23

Dr. Dudley Sargent

Answer 23

Harvard Hired him to help improve fitness of students

Question 24

Acute Responses

Answer 24

How body responds to individual bouts of Physical Activity

Question 25

Chronic Adaptations

Answer 25

Mark how the body responds over time to the stress of repeated bouts of exercise, referred to as training effects

Question 26

Carbohydrate

Answer 26

Short and long term systems

Question 27

Protein

Answer 27

Function depends on amino acid

Question 28

Fat

Answer 28

Glycerol: Short and long term systems | Fatty Acids: Long term system only

Question 29

Oxygen Deficit

Answer 29

The difference between oxygen uptake of the body during early stages of exercise and during a similar duration in a steady state of exercise

Question 30

Oxygen Debt

Answer 30

the extra oxygen that must be used in the oxidative energy processes after a period of strenuous exercise to reconvert lactic acid to glucose and decomposed ATP and creatine phosphate to their original states.

Question 31

Ventilatory threshold...

Answer 31

Predicts anaerobic threshold

Question 32

Relative Oxygen Consumption

Answer 32

Dividing oxygen consumption by your body weight

Question 33

Absolute Oxygen Consumption

Answer 33

However much oxygen you can put into your body

Question 34

Maximum oxygen consumption

Answer 34

The total amount of oxygen you can take in your body

Question 35

Total daily energy expenditure

Answer 35

10% feeding 60-75% RMR 15-30% Physical Activity

Question 36

Cell Structure

Answer 36

Cell Membrane: Semipermeable (Glucose) Nucleus: Genetic Material Cytoplasm: Anaerobic Processes Mitochondria: aerobic processes (POWER HOUSE)

Question 37

Substrates

Answer 37
