melaniej:
With the work:rest ratio, they'll give you easy data to work with, so add up all the top row, and the bottom row, and then simplify it til you get the smallest fraction.
So for your example, my brief adding up (may be wrong but close enough)
got 93:60
which is close to 90/60
which is a 2:1 WR ratio
Pretty sure thats right, got answers?
transgression:
Nope, no answers but I think you're correct.
Thanks for the help!

In past exams in reply to the question: 'How can an athlete work above 100% V02 max?'
You can simply say: 'By working anaerobically' or something as simple...
Add up all the work periods, and add up all the rest periods...might be something like work = 93 rest=60 (if you include low)
so 93/60 = 1.55:1 = Aerobic dominant...
ATP = 1:4+
LA = 1:2-1:3
02 = 2:1-1:2
Do I include low intensity activity as 'work'? Haven't thought about this before....in an exam i would include it... depending on the total of the work and rest that is...

How do you work this out?
akkxn:
Ahhh at first i was stumped. But don't be distracted by the ml/kg shit. Look at the total energy release.
Notice how its 100 and the contribution fromthe aerobic and anaerobic systems are 50% each.
So all you need to do is figure out the proportion for the other times.
Note: I had to check my book cos I never bothered to memorise them
But the answers are:
Duration: 120s, Total Energy Released: 150, Aerobic: 65% (about 100 ml/kg), Anaerobic: 35% (~ 50 ml/kg)
Duration: 180s, Total Energy Released: 200, Aerobic: 75% (150 ml/kg), Anaerobic: 25% (50 ml/kg)
BTW: I sure hope this question or something similar doesn't pop up, it's a bitch to "calculate" using my maths-illiterate head
