VCE PE Exam Discussion and Solutions

[johnno]

No it is D, due to aerobic training, the body has an increased ability to oxidise fats and carbohydrates aerobically at a higher intensity for longer, reducing the demands of ATP production from anaerobic glycolysis, thereby delaying LIP

Have to agree with Tom here, LIP and lactate tolerance and independent of each other. Increase in lactate tolerance means you can maintain the (anaerobic) intensity above your LIP (an aerobic measure) where you are in fact accumulating H+ ions. Tolerance means you still accumulate them but are able to buffer (effectively neutralise) the lactate.

For question 4b would they accept the training principle of duration or detraining? I put duration.

I doubt they's accept duration as the graph is displayed over days (84 days) instead of minutes and hours

[NathanG]

These answers make me so happy. I thought I stuffed the MC, but going off these answers I got 13/14 ! So happy seeing as I’ve held A+ all year and I thought I wasted it away on the exam

[charlottekennedy12345]

Yeah you do have a fair point! I can see where you are going with this. But I am not sure at this point because they are both relatively correct.

I think 3 is A because insufficient oxygen could mean contribution from ATP-PC which won't product lactate

[johnno]

Anyone got thoughts on any of the following:

Questions 2.c. ('Describe the stretch shortening cycle that occurs in this type of exercise')- A rapid eccentric contraction followed by forceful concentric contraction?

6.a. (Netball program) Was there a policy component? Or physical environment, I suggested from the information provided there is no evidence to suggest there was p.e, but supplying courts was the likely way they targeted this aspect.

11.c. (Graph providing hr and speed) If I provided evidence will long interval be accepted?

13.c. (6x30 meter sprints) Predominant system? Could almost be any of the three

anyone have suggested answers to PE exam?

For 2.c Personally i Never learnt that in class, so i said that the muscles go through their full range of motion or something (definitely lost marks there)

6.a. Yes i agree there wasn't much evidence of P.E. and i too said that providing courts and netball equipment was the only seen evidence, i think for policy you could have said the rules not only in-game but the policy to having to pick one program?? Not sure will have to see answers

11.c. Yes Long Interval is a valid option, especially if you used the right data to support, what as your other stated method? (I did continuous and Fartlek)

13.c. I said Aerobic, simply because it asked for PREDOMINANT energy system, and aerobic would have supplied like 70-80% of total energy, with added contribution from anaerobic glycolysis only when intensity was above 85% max HR

Thanks, yeh I said continuous for 11 for the other (stops in the run could be due to stopping at traffic light). Aerobic seems like the best answer for 13, unfortunately I panicked and said anaerobic glycolysis, probably the least likely of the 3

Examples of physical environment could be the netball games being played at designated courts, which are located in almost every town/suburb.
Policy could include the pay as you play, which aids parents and individuals as they don't have to pay for expensive and contracted gym memberships

I don't think 13. c) is the aerobic system, because first of all the work to rest ratio is approx 1:5, indicating a strong reliance on the ATP-PC system to provide energy for ATP resynthesis in a sprint (which is done at max intensity), and secondly in between sets the energy demands of the body are low, and therefore the aerobic system wouldn't have to help produce significant amounts of energy compared to that of what the ATP-PC system would in the sprint. The aerobic system's main purpose in this situation would be to phosphorylate PC stores, which doesn't correlate with it being predominant (meaning greatest contributor to ATP resynthesis).

I said it was Anaerobic glycolysis as evidence in how Jarrod Berry got "4th overall: 24.99s." Remember, the aerobic system doesn't become predominant until 60seconds+

Yes this is very true, I think this Q has stumped a lot of people..
Later on in the Q it asked for the most likely cause of fatigue and the best recovery method, what did you (or anyone else) say for them?

Depletion of fuels and active recovery.

[Anguspana]

Depletion of fuels should be right, but I'm pretty sure it's passive recovery to replenish PC stores

[NathanG]

Depletion of fuels and active recovery.

I also said depletion of fuels, but said passive recovery in order to replenish lost CP stores to complete the sprints
