Thoughts on exam?

[jess123]

also about the last question where it asks the predominant fuel throughout the ride. would fats be correct to some degree as the ride is a 21km so she would deplete her glycogen stores

[peachesandcream]

For Question 14bii, I talked about how she can analyse her HR data and after a period of time work out when her heart rate starts to decrease and hence become "too easy" and thus apply the principle of overload into her training program. Is that correct or have I overthought it a little?

We're discussing this one, and we'll get back to you. However, 21km is too short for any substantial glycogen store decreases.

Hmm, that's a clever answer, and i was going to say I'd definitely pay that if I were me marking it, but I went back to the question and I'll change that to "maybe".
Reasons: a) it says "which training principle", suggesting they only think one is possible, and b) it's "while riding", so intensity can be monitored here (I suppose you could say that for overload too, kind of, but let's see). 

We'll probably issue one last update soon, so stay tuned

I listed Intensity for the first part, just talked about it differently for the second.

^ Oh, then yeah, that should be fine, I'd say — I think, you might've needed to mention the terrain/location somehow, though.

Updated our solutions again with a few more clarifications, including to MC Q5.

also about the last question where it asks the predominant fuel throughout the ride. would fats be correct to some degree as the ride is a 21km so she would deplete her glycogen stores

As Lex has mentioned above, she would not have depleted glycogen stores in 21 km of bike riding. You may be getting confused with 21 km of running (i.e. half marathon) or around ~90 mins, which is inside the generally accepted 50/50 range. Bike riding is much quicker than running, and so we cannot assume glycogen depletion as a major factor - we would be looking at intensity factors (i.e. "justify using data").

Having said that, it is technically possible to argue that lipids are the predominant food fuel for one or two of Alice’s rides, but we don't believe that will be a considered correct by the VCAA. I've updated our solutions to provide an explanation - so please have a look there again, on the page after question 14d.

You mentioned above that you specified intensity for the first part. That's fine.

For the second part, what you've said there is also correct, and I would pay you the marks for that too. I think the spirit of the question wanted you to use your answer from the first part, but they haven't really explicitly stated that, so I would think your response is acceptable.

how did other people from your school, find the exam?

[braydenhawkins]

Hey guys! Just a question, on the marathon fatigue question I said the athlete would have a greater lactate/H  accumulation in the final sprint and the. Explained how this contributed to greater fatigue. And then I went on to say that glycogen stores would most likely be depleted and how fats have a slower rate and thus the athlete must slow down. Would I get full marks for this question

[braydenhawkins]

And also for the overload questions would simply saying 'increased repititions' or 'increased weight/load' have sufficed for full marks because the space wasn't big enough to go into detail about it all?

You will definitely get some marks for your glycogen depletion explanation, but unlikely to get marks for your H+ accumulation explanation.

Yes, H+ accumulation could be a cause of fatigue, but if it was in the final sprint, wouldn't the final time be quicker since we're using the anaerboic glycolysis system (faster rate)?

To argue for H+ accumulation, you would have needed to say that the athlete was running at slightly above LIP in the first 30 km, and it was this slow accumulation that ultimately caused them to slow down significantly for the last 10 km due to the decrease in anaerobic glycolysis' contribution. Note that this is plausible, but not likely, as to use anaerobic glycolysis you need glucose/glycogen. But we're arguing that glycogen has already depleted!

And also for the overload questions would simply saying 'increased repititions' or 'increased weight/load' have sufficed for full marks because the space wasn't big enough to go into detail about it all?

Yes, not because of space though. The example they gave was "carrying a weight while lunging", so "increasing repetitions" would be fine.

Saying by 10% is ok right ?

[Dismounted]

Saying by 10% is ok right ?

If you said "increase repetitions by 10%", that would be okay (and a better response). You just don't get any extra marks for saying it.

Haha I wasn't expecting too

[braydenhawkins]

So even if I had the right answer for full marks there, will they take some off for the H  accumulation
