What are the 5 Concepts of Physical Fitness?
|
Muscular Strength, Muscular Endurance, Cardiorespiratory Endurance, Range Of Motion and Body Composition.
|
|
|
What are the numbers for Essential Body Fat?
|
For Men- 2-5% body fat
For Women- 10-13% body fat |
|
|
What are the three basic processes that must interact to deliver adequate blood and nutrients to the tissues?
|
Pulmonary Ventilation (getting oxygen to the blood), Cardiac Output (delivery of oxygen to the tissues) and extracting oxygen to complete metabolic process of ATP.
|
|
|
What two things determine oxygen-carrying capacity?
|
The ability of the alveoli to ventilate in the lungs and the hemoglobin concentration in the lungs.
|
|
|
What is anemia?
|
Less than 12g of Hb per 100 mL of blood.
|
|
|
What is the formula for Cardiac Output?
|
Q=HR x SV
Heart Rate (beats per a minute) x Stroke Volume (quantity of blood pumped per heartbeat) |
|
|
What is normal Cardiac Output during rest?
|
Approximately 5 liters (1.3 gallons) per minute.
|
|
|
During maximal exercise, what is normal Cardiac Output?
|
Approximately 20 - 25 liters (5 to 6.5 gallons) per minute.
Up to 30 to 40 liters in highly trained individuals. |
|
|
What is Ejection Fraction?
|
The percentage of the end diastolic volume that is ejected with each contraction of the heart.
|
|
|
Where does aerobic production of ATP take place?
|
In the mitochondria.
|
|
|
What are the simplest form of nutrients?
|
They are glucose, fatty acids and amino acids.
|
|
|
How is excess glucose stored in the liver and muscle cells?
|
As glycogen.
|
|
|
What is gluconeogenesis?
|
It is the process of taking amino acids in the liver to be converted to glucose.
|
|
|
How long can the Phosphagen System provide energy?
|
Approx. 10 secs. of exertion.
|
|
|
What is Pyruvate?
|
It is glucose that has been broken down into energy to be used in the mitochondria.
|
|
|
What happens to Pyruvate when an insufficient amount of oxygen is available?
|
It converts to lactate.
|
|
|
How long does the anaerobic glycolysis energy system provide energy?
|
Typically from 1 to 3 minutes.
