Apart from the LIP as it was poorly done last year what do you guys think will be on the exam?
-
Finite capacity of the anaerobic systems.
And you can predict a lot more of the questions, just look at past exams, they repeat the same question 'types'.
-
Cheers mate
-
Apparentely specific fitness components wasn't on the exam last year. So I guess it has a bigger chance of popping up this year
-
gday guys,
got the exam monday, was just wondering what finite capacity means in relation to the energy systems?
seems to be popping up a fair bit in practice exams and ive got no idea?
:-\
-
Yeah just saw that in the 2004 exam. The assessors report had some half-assed explanation which didn't even make sense.
In relation to energy systems, I think finite capacity refers to the oxygen deficit created by the anaerobic systems, namely the ATP-PC system which has finite stores of PC therefore a finite capactiy?
However I'm still confused how it relates to the LA system. Anyone?
-
Hydrogen ions limit the function of the LA system.
-
yeah that sorta makes sense,
im just going to interpret finite capcity as the factor which limits the energy system from opperating,
ATP-PC : limited PC stores
LA : H+ ion accumulation
Aerobic : oxygen deficit / depletion of glycogen stores
correct me if im wrong :)
-
Um...Aerobic system is pretty much infinite..maybe? someone correct me on this?
Depletion of glycogen stores would be a fatiguing factor though, doesn't stop it from working.
-

Yeah aerobic energy system has an (reletively) infinite capacity. Apparentely we can walk for 50 hours non-stop using the fat stores in our body
Thanks for clearing up the finite capacity of the LA system
-
Can somebody tell me if this person meets the NPAGs:
a) Exercise on 5 days of the week, for a total of 120minute (included in that is 30minutes of vigorous activity)
-
yes, vigourous activity counts as "double" minutes according to one of malpeli's prac exams
-
Yeah thats what I also read.
-
Hmm actually, the NPAG guideline is: at least 30mins per day in total, at least 5 times a week. So on one of those days, the person didn't get 30mins... so technically they didn't make the cut lol. Still not sure, do you have solutions?

isnt it refered to now as aerobic potential?
-
Yeah, i wouldn't use that term LOL.
It's aerobic power (rate of producing ATP using oxygen)
and aerobic capacity (total amount of ATP that can be produced using oxygen)
-
you sure, our teacher was steadfast on the fact that its aerobic potential instead of capacity.
-
its capacity mate, say potential in the exam and u will get murded
-

that all depends on the person too, if they are a child/youth then no they;re not because they require 7 days to meet the npag
-

It's not capacity, it's potential. There is no limit to the aerobic system, If fuel never ran out it could run infinitely.
-
im stayin with capacity
-
yeh i see aerobic capacity printed in my text book but i see no aerobic potential
-
you also see anaerobic threshold? using that term tomorrow by any chance?
-
Yeah, anaerobic threshold is awesome.
-
you can still say anaerobic threshold,
nothing wrong with that.
anyway gl to evry1 for tomoz, fingers crossed for a good exam,
guess il be on after it comparing answers ;D
-
...okay... anaerobic threshold...doesn't mean LIP whatsoever, completely different term. right. gotcha.
-
your my hero mate, i swear when i grow up i wanna be just like you.
anaerobic threshold is the wrong term.
-
?
-
you cannot say aerobic capacity; the correct term is aerobic potential. effectively as long as there is fuel, the aerobic system can run.
you can say ANaerobic capacity because it is finite; it depletes/comes to an end.
-
pretty sure the words aerobic potential havent appeared all yr in live it up, always capacity
-
its capacity.
-
LMAO.
I don't do PE. but this is gold. :)
Good luck all!
-
it's not in the text books because it is new science; the textbooks were published before the LIP also.
no such thing as anaerobic threshould anymore, it's LIP.
-
My friend who wants to get a 50 for PE says it's CAPACITY! :angel:
-
its capacity if vcaa wanted you to use potential which has never came up in a book before than they would have told everyone just like they did with the anaerobic threshold and lip
-
Just pouring some more fuel on the fire; it's potential.
-
It's definetly potential. My dad is a VCAA marker and he says capacity WONT get full marks
