Question 1

is there less oxygen on top of a mountain

Answer 1

no
its the partial pressures
therefore you actually have less oxygen in your blood because you burn it faster

Question 2

when co2 is really high and o2 is low then

Answer 2

youll breath a lot more

changes exponentially

Question 3

if two people have the same vo2 max and someone hits their lactate threshold at 50% and the other hits it at 85% Who will run faster 10km

Answer 3

the 85%

if you can train well and have a higher lactate threshold then you will be able to run faster

Question 4

high intensity training intervals is a great training method because

Answer 4

you use all your energy systems all the time
train the oxidative phosphorylation system that all the pyruvate goes into the mitochondria then you will produce less lactate and it will make you run faster

Question 5

when youre doing high intensity exercise lactate goes and blood ph changes in

Answer 5

up

proportion to the lactate (so lactate is almost just like ph)

Question 6

we need to buffer the change in ph and lactate by

Answer 6

using the pathway of a bicarbonate buffer (like a sponge) as you add acid then the hydrogen ions soak ups the acid

when theres too much bicarbonate and not enough acid then the sponge releases some and vise versa

Question 7

does respiration or ventilation limit sport performance

Answer 7

No (only MIGHT happen in diaphragm fatigue or disease states)
