Block 3 {Cardiovascular Training}

Question 1

How much blood does the heart pump each minute during maximum-intesenity aerobic exercise?

How about at rest?

Answer 1

1. 20 quarts per min
2. 5 Quarts per min

Question 1

Military aerobic movements?

Answer 1

1. Building a Fighting Position
2. Loaded Foot Movement
   3.

Question 2

Cardiorespiratory system?

Answer 2

Heart, Lung, Blood vessels

Question 3

How many beats and breaths to you take on average during REST or LIGHT ACTIVITY?

How about during intense exercise?

Answer 3

1. 50-90 beats per min
2. 12-20 breaths per min

170-210 beats per min and 40-60 breaths per min

Question 4

What is a good resting blood pressure?

How about during exercise?

Answer 4

1. 120/80 mmHg - 120 (systolic) and 80 (dystolic)
2. 175/65

Question 5

Where is your heart rate during intense exercise?

Question 6

Stroke volume?

Does it increase during exercise?

Answer 6

The amount of blood the heart pumps with each beat
Yes it increase meaning more blood per beat

Question 7

Cardiac output?

Answer 7

THe volume of blood pumped by the herat per minute via heart rate and stroke volume

Question 8

How much blood goes to working muscles?

Answer 8

1. 85-90% of the blood may be delivered to working muscles (During Exerscise)
2. 15-20% fof the blood is distributed to skeletal muscles

Question 9

Metabolic Rate?

Metabolism? At rest? during exeruse? How high can Olympic runners go?

Answer 9

The rate at which your body uses energy
1. Rest = Low rate
2. Exercise: increase to 800% of rate
3. Olympic runners = 2000%

The sum of all the chemical process necessary to maintain the body

Question 10

ATP?

What produces ATP?

Answer 10

Adenosine Triphosphate - The energy source for all celluar processes

Mitochondria

Question 11

What energy system fuels aerobic endurance?

What enrgy source does it use? What are its characteristics?

Answer 11

**Oxidative Energy System - **The system that supplies energy to cells for long periods of activity through breakdown of glucose, glycogen, and fats - Chemical reactions REQUIRE OXYGEN
1. For exercise that last longer than 2 minutes
2. Cannot produce energy quickly but lasts longer
3. Energy stores are much greater than other systems
4. Uses both carbohydrates and fats (but mainly fats)
5. Increased mitochondrial capacity and number is the key

Question 12

What is VO2 Max?

Answer 12

Maximal oxygen consumption - The highest rate of oxygen consumption an individual is capable of during maximum physical effort

Question 13

How is physical fitness related to energy production?

Answer 13

More fit people transport energy more efficiently and they are able to cope with lactate better.
