Heart, Blood Vessels, and Blood. |
Cardiovascular System |
|
Lungs, Air Passages, and Air. |
Respiratory System |
|
The ability to exercise your entire body for a long period of time without stopping. |
Cardiorespiratory endurance |
|
It requires a strong heart, healthy lungs, and clear blood vessels to supply large muscles with oxygen. |
Cardiorespiratory endurance |
|
During vigorous physical activity IT must pump more blood to to supply additional oxygen and remove additional waste. |
Heart |
|
Two ways the heart can get more blood to the the muscles and organs. |
1. Beat faster. 2. Send more blood with each beat. |
|
In the ________, oxygen is transferred from the air to the blood for transport to the tissues of the body. |
Lungs |
|
Fit people can take in more air with each breath than unfit people because they have more efficient _________. |
respiratory muscles |
|
A waxy, fat-like substance found in meat, dairy products, and egg yolk--can be dangerous because high levels can build up in your body without you noticing it. |
Cholesterol |
|
Cholesterol is carried through your bloodstream by particles called ____________. |
lipoproteins |
|
Carries cholesterol that is more likely to stay in your body and contribute to atherosclerosis. |
LDL |
|
"Bad cholesterol" |
LDL |
|
LDL |
low density lipoprotein |
|
It carries excess cholesterol out of your bloodstream and into your liver for elimination from your body. |
HDL |
|
"Good cholesterol" |
HDL |
|
HDL |
High-density lipoprotein
|
|
Regular physical activity helps improve your health and resist disease by reducing your ______ and increasing your ______. |
LDL / HDL |
|
Carry blood from your heart to another part of your body. |
arteries |
|
Fatty deposits on the inner walls of an artery lead to atherosclerosis. If atherosclerosis leads to a complete block of blood, and thus oxygen to the heart, a ________. |
heart attack occurs |
|
Carry blood filled with waste products from muscle cells and other body tissues back to the heart. |
Veins |
|
Because your heart is a muscle it benefits from ________. |
exercise |
|
Squeeze the veins to pump blood back to your heart. |
muscles |
|
Keep the blood in veins from flowing backwards. |
valves |
|
Lack of exercise can cause the valves in your veins to work less efficiently resulting in poor __________. |
circulation |
|
When your heart can supply the necessary oxygen for your muscles to work it is an _________. |
aerobic activity |
|
The number of times your heart beats when you are relatively inactive. |
Resting heart rate |
|
Maximum heart rate minus Resting heart rate equals- |
heart rate reserve |
|
The highest heart rate a person can reach during the most vigorous exercise. |
maximum heart rate |
|
Two methods for determining target heart rate. |
1. Percent of heart rate reserve. 2. Percent of maximum heart rate. |
|
To effectively improve your cardiorespiratory endurance you need to to participate in vigorous activity at least _______. |
three days a week |
|
To improve your cardiorespiratory endurance your exercise time should be at least _______. |
20 minutes a day |
|
To improve your cardiorespiratory endurance your vigorous exercise should be of a high enough intensity to increase your heart rate above your __________. |
threshold level |
|
The recommended frequency for cardiorespiratory endurance is _____. |
3 to 6 days a week |
|
220 minus your age = |
maximum heart rate |
|
To improve your cardiorespiratory endurance your vigorous activity should be of a high enough intensity, that it increases your heart rate above a threshold level, and into the _________. |
target fitness zone |
