Q

What impacts stroke volume? (5 factors)
1) ______ return to heart (deoxygenated blood that returns to the right atrium)
2) ____ ventricular capacity to _______
3) contractility force of heart (allows more blood ejected per beat)
4) ________ pressure (higher arterial pressure makes it harder to eject blood, reduces SV)
5) sympathetic stimulation

A

1) venous
2) left, enlarge

Q

Formula for MAP (mean arterial pressure)

A

17
Q

magnitude of change in VO2max depends on __ (2 factors) during chronic exercise
1) ____ principle
2) Baseline activity level

A

1) FITT

18
Q

main difference between acute and chronic training
In acute training, __ levels off and the increase in VO2 max is predominantly b/c of __ (after __-__% VO2 max). In Chronic training, __ accounts for the increase in CO, while __ has little difference/decrease.

A

SV
HR
40-60%
SV
HR

19
Q

difference between cardiac output and SV
cardiac output = blood pumped out of heart per ______
SV = blood pumped out of heart per ____

A

minute
beat

20
Q

skeletal muscles changes
1) Increase in ________
2) Increase in myoglobin
3) Increase size of ____-twitch muscle fibers

A

1) capillaries
3) slow

21
Q

metabolic changes
1) increase in the # of ____________
2) increase in mitochondria enzymes
3) increase stored ________

A

1) mitochondria
3) glycogen

22
Q

concentric contraction (muscle) _______ blood flow and compresses the ________ system. In response, the body issues an increase in __.

A

reduces
arterial
BP

23
Q

True or false: A trained individual would have a lower stroke volume as compared to an aerobically untrained individual

A

False, b/c aerobic training strengthens the heart, allowing it to pump more blood per beat.

24
Q

Oxygen _______ occurs at the beginning of exercise when the _______ of O2 exceeds supply; on a graph, it’s the ____ between rest and steady state. The body turns to _________ sources of energy while it adapts (ex. glycolysis) which results in _______ buildup and metabolites.

A

deficit
demand
area
anaerobic
lactate

25
Q

Oxygen ____ occurs after exercise when the body recovers. Oxygen consumption will be ______ than it was at the beginning stage of rest, as the body adapts to return to homeostasis by replenishing _________ stores.

A

debt
higher
anaerobic

26
Q

the reason why venous return to heart increases SV in the supine position is because of the _______ effects of gravity. The body is in horizontal alignment, so the body doesn’t have to work against gravity as hard to bring blood back to the heart, thus more blood can be pumped out.

A

reduced

27
Q

The ________ arteries outside of the heart supply oxygenated blood to the heart muscle

A

coronary

28
Q

________ carry oxygenated blood away from the heart to tissues; _____ return deoxygenated blood to the heart for reoxygenation.

A

arteries
veins

29
Q

difference between the central and peripheral components of the oxygen transport system
central = the ________/transport of oxygen (pumping action of the heart; expressed as CO)
peripheral = the utilization of oxygen by tissues

A

delivery

30
Q

For the peripheral component, the formula for a-vo2 difference is the oxygen content in the ________ subtracted by the oxygen content in the _____. A higher a-VO2 different entails that muscles are ___________ more oxygen to meet energy demands.

A

arteries
veins
extracting

31
Q

In acute exercise, the increase in heart rate is directly proportional with _________. HR increases for - min, then levels off, which is called ______ state.

A
