how should the athletes use thier transitions?
27
o2 transfer is there to support the anaerobic
28
sprinters have very little aerobic energy system used. they do not need to
29
worry as mcuh about gas transfer

33
1500m runner has to do more gas transfer compared to the anearobic. the
34
longer the run the longer the aerobic is
35
400m is hard as you need both the aerobic and anaerobic gas transfers
36
equally so you need to train both
37
50 seconds of less energy comes from atp stores and pcr

the longer the race the more aerobic and therefore the more the sustained

PO2 w/ 40mmhg you would be unconcious and when it reaches 20 you will die

when plane loses pressure you have 15seconds to put mask on before you

lose consciousness

the value he got would mean death at sea level- 24mmhg
56
are the enzymes inside the sucessful climbers have a biological advantage or
57
better adaptations (aclimitising to the altitude)(what tactics should be used

faster or slower)
