F - Cardiopulmonary Adaptions to Exercise - Suminski

Question 1

What is the purpose of CP adaptions?

Answer 1

Create ATP with stored E to meet demands of physical activity while reducing the stress of exertion

Question 2

2 skeletal muscle cell adaptions?

Answer 2

Glycogen - PFK, mitochondria

FFA - mitochondria

Question 3

Cardiac Output =

Answer 3

Stroke volume x HR

Question 4

A-vO2diff part of Fick equation gives an indication of?

Answer 4

The O2 saturation level difference between arterial blood and mixed venous blood.
**the amount of oxygen needed by the tissues

Question 5

Fick Equation

Answer 5

VO2max = (Stroke volume x HR) x (A-vO2difference)

Question 6

What does the stroke volume look like post training?

Answer 6

It is decreased

• the LV is increased - can hold more
• wall thickness increased - more forceful contraction

Question 7

What does the Frank-Starling Law of the heart show?

Answer 7

The relationship between EDV, contraction strength, and SV

Question 8

Typical results for untrained?

Answer 8

EDV = 100ml
ESV = 40ml
EF = 60%

Question 9

Typical results for trained

Answer 9

EDV = 150ml - Increased
ESV = 30ml - decreased
EF = 80% - increased

Question 10

What is the average EF?

Answer 10

55-60%

-as high as 80% for trained athletes

Question 11

What are some factors that can affect stroke volume?

Answer 11

Age, gender, HTN
PHTN, Genetic, Tachyarythmias, structural dz
*Blood volume - hypovolemia, hypervolemia
