energy supply and the effects of exercise on the body Flashcards
1
Q
what is aerobic respiration
A
respiration that takes place in the presence of oxygen
2
Q
what is the equation for aerobic respiration
A
glucose + oxygen –> carbon dioxide + water
3
Q
what is anaerobic respiration
A
respiration that takes place in the absence of oxygen
4
Q
what is the equation for anaerobic respiration
A
glucose –> lactic acid
5
Q
what kind of activity requires aerobic respiration
A
long duration, low/moderate intensity
6
Q
what kind of activity requires anaerobic respiration
A
short duration, high intensity
7
Q
how does EPOC work
A
- excess post-exercise oxygen consumption
- caused by anaerobic exercise producing lactic acid
- high breathing rate and rapid HR to remove lactic acid
8
Q
what are the factors affecting recovery time
A
- overall fitness
- genetics
- age
- gender
- sleep
9
Q
what are the short term effects of exercise
A
- HR increases
- breathing rate increases
- red skin/sweating (heat control)
- fatigue
- nausea
- light-headedness
10
Q
what are the long term effects of exercise
A
- increase in heart size (hypertrophy)
- lower RHR (bradycardia)
- increased stroke volume
- higher lactic acid tolerance
