Chapter 6

Question 1

THe primary function of the cardiovascular system during aerobic exercise is to ?

Answer 1

delever oxygen and nutritents to the muscle

Question 2

cardiac output

Answer 2

the amount of blood pumped by the heart in leters per minute

Question 3

cardiac output is determined by?

Answer 3

the quantity of blood ejected with each beat (stroke volume) and the hearts rate of pumping (heart rate)

Question 4

stroke volume

Answer 4

blood ejected with each beat

Volume=how much

Question 5

Cardiac output formula

Answer 5

stroke volume x heart rate

Q+SV x xHR

Question 6

college men maximal stroke volume

Answer 6

100 and 115 ml of blood

Question 7

what is responsible for the regulation of stroke volume?

Answer 7

end-diastolic volume and the action of catecholamines (epinephrine and norepinephrine

Question 8

end-diastolic volume

Answer 8

the volume of blood available to be pumped by the left ventricle at the end of the filling phase (diastole

Question 9

venous return

Answer 9

the amount of blood returning to the hear

Question 10

frank-starling mechanism

Answer 10

with aerobic exercise more blood returns to the heart diastolic volume is increased, myocardial fibers become more stretched , more forceful contraction of systolic ejection

Question 11

how to calculate maximal HR

Answer 11

220-age plus or minus 10

Question 12

how to calculate VO2 max?

Answer 12

cardiac output x arteriovenous oxygen difference

Question 13

systolic blood pressure

Answer 13

the pressure exerted against the arterial walls as blood is forcefully ejected during ventricular contraction (systole)

Question 14

diastolic blood pressure

Answer 14

the pressure exerted against the arterial walls when no blood is being forcefully ejected through the vessels

Question 15

total peripheral resistance

Answer 15

the resistance of the entire systemic circulation

Question 16

acute aerobic exercies results in an increase of?

Answer 16

cardiac output
stroke volume
HR
oxygen uptake
systolic blood pressure 
blood flow to active muscles

Question 17

acute aerobic exercise results in a decrease of?

Answer 17

diastolic blood pressure (decrease=diastolic)

Question 18

minute ventilation

Answer 18

the volume of air breathed per minute (increases with exercise)

Question 19

tidal volume

Answer 19

the amount of air inhaled and exhaled with each breath

Question 20

aerobic endurance training adaptations of muscular strength and sprint speed, anaerobic power, and maximal rate of force production

Answer 20

no charge

Question 21

aerobic endurance training adaptations for muscular endurance and aerobic power

Answer 21

increase

Question 22

Answer 22

no change

Question 23

aerobic endurance training adaptations for capillary density and mitochondrial density

Answer 23

increases

Question 24

aerobic endurance training adaptations for creatine phosphokinase, myokinase and sodium potassium atpase

Answer 24

increase

Question 25

aerobic endurance training adaptation for stored ATP, stored creatine phosphate, stored glycogen, stored triglycerides

Answer 25

increases

Question 26

aerobic endurance training adaptations for ligament strength and tendon strength

Answer 26

increases

Question 27

aerobic endurance training adaptations for % body fat

Answer 27

decreases

Question 28

aerobic endurance training adaptationsfor fat-free mass

Answer 28

no change

Question 29

biggesst change is chronic cardiovasular funtion of aerobic endurance training

Answer 29

increase in maximal cardiac output
