Resource Delivery during Exercise Flashcards
1
Q
what is needed to make ATP
A
- fuel
- > carbs or fats (rarely protein) - ideally O2
- a mitochondria
2
Q
the aerobic process
A
3
Q
describe gas exchange pressures at rest
A
4
Q
composition of air
A
5
Q
VO2 max
A
maximal oxygen uptake
6
Q
epinephrines role in exercise
A
epinephrine (adrenaline) that is released during exercise will lead to systemic vasoconstriction
- > since muscles need MORE blood flow during exercise they will release locally acting vasodilators to increase BF in local area
7
Q
describe a normal heart rate
A
a normal resting HR is usually 70bpm
- > children have higher resting HR
- > highly trained athletes will have lower resting heart rates
8
Q
max heart rate
A
typically defined as 220 - age
- > better approximation is 207 - 0.7xage
9
Q
karvonen formula
A
tells you the heart rate your should have at a certain percentage of effort
10
Q
cardiac output (Q)
A
Q = SV x HR
- > average Q at rest is 5L/min
- > at max exercise = 22-35L/min
