How was it?

[BiG DaN]

Likewise, it was definitely A.

Just to let you know, the multiple choice section has been added to my website with potential answers, I am also going to post a few short answer questions as well.

dam got 2 MC wrong
q2 i put the 400m lol
q7 i put c or d cant remember

[lexitu]

Nah don't worry mate, I'm not 100% sure on Q7... there were too many dubious questions this time. On the other exams I could be sure on pretty much all of the multiple choice questions.

u gonna scan the rest of the exam? even without solutions it would be good

i got a question about your suggested respne to question 5 aswell

how does the aerobic system contribute to the replenishment of creatine phosphate?

i put B. i'm pretty sure there is a question on one of the vcaa exams in the last couple of years that is pretty similiar

my logic was that by having a good aerobic system providing ATP there is less reliance on the lactic acid sytem to provide ATP. by having less reliance on the lactic acid system there is a lesser amount of the fatiguing by-products that sytem creates.

the wording of this question i find a little confusing... for option A it says "atp-pc replenishment" however it isnt actually replenishing atp-pc but rather pc...
i dont remember which one i selected in the end but i remember thinking about it for a while
what does anyone else think??

[ferrim]

terribly worded question

is it talking about the ATP-PC energy system

or adenosine triphosphate and phosphocreatine individually?

students shouldn't be required to intepret VCAA's shit

Sorry guys... some short answer bits are about to be uploaded, just the site is being a bit slow.

In regards to question 5.. it is definitely A - the aerobic system helps with this during EPOC - their is an "alactacid" phase and a "lactacid" phase where lactic acid is removed and where PCr is replenished. 100% sure. ATP stores are also being replenished as well.

i definately know that pc and atp are being replenished by aerobic es.... but atp-pc is an energy system not either of these fuels??
lol it is only one mc but i think it is crap wording if a is right

[krm]

Yeah I thought the answer was A because of the alactic debt
which is the first 2.5L of O2 consumed during recovery which is used to resynthesis ATP and PC

[lexitu]

Yep thats right mate (krm). Others, also note that athletes actually use more of their lactic acid system during maximal efforts due to a higher glycolytic capacity. P.123 and p.273 Nelson for reference.

it says "ATP-CP stores" so that implies the stores of the atp-pc ES are PC
i agree with it being ambiguous tho

i agree with all that and know EPOC back to front but i still dont agree with the answer because atp-pc isnt a fuel
lol
anyway i agree to disagree.. although im sure you will be right when it comes to the solutions coming out because it is everyone against me
haha
thanks for explaining though

[BiG DaN]

would aerobic training be valid for q10b about epoc

[lexitu]

You have to acknowledge that ATP itself is also a fuel. Obviously it's being continually resynthesized but pre-existing intramuscular ATP stores are also used.

[lexitu]

yeah aerobic training should be fine.. my answers weren't that clear, it can be reduced either during exercise or after exercise as well.

VCAA exam 2008
Strategies to reduce EPOC include: •   lower core temperature •   undertake a passive recovery •   acclimatisation •   reduction in intensity of exercise •   more aerobic training.

Practical examples include: •   immersing the athlete in an ice bath •   placing cooling towels on the athlete •   re-hydrating the athlete with a cool drink •   having the athlete take a cold shower •   fanning the athlete •   sitting the athlete in the shade •   resting the athlete after exercise •   training the athlete in similar climates.
