Thickening and hardening of artery walls
33
Explain the body mass index (BMI)
Determining whether you are overweight or underweight using the energy equation
34
Explain dehydration
Affects human performance Loss of water Loss of electrolytes
35

Over 31
40
Obesity reduces life expectancy at the same rate as what?
Smoking
41
When you exercise you lose what?
Protein
42
What two essential nutrients are a source of energy?
Carbohydrates and fats
43
What is a heat cramp?
- A muscle spasm or tighten due to excessive loss of fluid and electrolytes through sweating - Short, painful muscle twitches then a total muscle cramp
44
What is heat exhaustion?
- cumulative loss of water and weakening of body's ability to regulate its internal temperature - pale, high body temp, clammy, lightheaded, unconscious
45
What is a heat stroke?
- Complete failure of the body's regulation system | - very high body temperature, headache, confusion, unconscious
46
What happens to sugar in a fit person?
The sugar goes to the muscle and it can burn it off right away, 20 minutes after eating
47
What happens to sugar in a fat person?
Sugar goes to fat and gets stored
48
What happens to cholesterol in a fit person?
HDL (good kind) cholesterol goes to the liver and gets wrapped in protein and mixes in the blood
49
What happens to cholesterol in a fat person?
cholesterol goes to the liver and gets wrapped in protein then stays in the liver as LDL (bad kind)
50
Describe a fat cell in a fit person?
Enzymes in the fat cell are more efficient therefore they will break down the fat quicker
51
What are the two different enzymes found in fat cells?
Lipogenesis and lipolysis enzymes
52
What effect does exercise have on the enzymes in fat cells?
Enzymes grow each time and each consecutive time the fat can leave quicker because of the bigger enzymes
53
In order to burn fat your muscles need____?
Oxygen
54
The three things the muscle means for combustion are:
Fats, sugar, and oxygen
55
What is the best fat burning exercise?
Something that uses big muscles, long in study for 15 minutes minimum, and being able to talk throughout the exercise
56
What is the most popular performance enhancing supplements?
Creatine
57
What is creatine known for?
It claims to be able to increase the phosphocreatine storage in muscle which increases speed, power, and strength
58
What is an example of a physiological aid?
Blood doping
59
What is blood doping?
Injecting yourself with more blood cells, thereby increasing the total volume of oxygen- carrying blood cells
60
What are three points about EPO?
