Hi,
Just wanted to start a forum here for all the questions everyone has related to P.E 3/4 for 2013, since it'll be easier to keep track of questions and answers and avoid mass-production of 'topics'.
Hopefully, this forum page will be useful for those who have similar questions as well.
Thanks! 8)
MangoPengy ::)
First Question is: What advice can be given for a SAC (Case Study) that is written in 'report format' regarding Chapters 1-3? Is there any way to obtain past SACs for Outcome 1? Thanks.
-
Hey fellow PE student! check the study design and look at the outcomes for AOS 1.
Important things to remember are:
The National guidelines to PA, these are so vital, you should be able to recall them in your sleep!
Know the subjective and objective measures of PA and for each measure know 2 or 3 advantages and disadvantages. Take note of the dimensions they measure, this again is so vital.
The SE model is extremely important, you need to be able to apply it to a random setting using the 4 levels of influence.
Also know how to draw one up. Ask yourself why is it important to target multiple levels of influence rather than just one.....AND finally....
Understand the settings used to promote physical activity: school, community and workplace be able to apply this and be able to name some strategies used to promote PA in these settings.
Best of luck!! My sac is in 5 days I think, when is your sac?

Hey im not quite sure what you mean by case study, im assuming you mean you will probably get a program and have to answer questions on and focus heavily on the socio-ecological model.
I dont have any sacs to give you but why dont you get some books. I recommed getting the A+ practice exams questions, they are brillant also the checkpoints books is very good.
Ask any questions you like :) :)

Is this an open question thread? I'd start my own thread, but I thought it may be easier to just post here.
I'm having difficulties understanding what contributes to the resynthesis of ATP? I'm confused as hell, at one second it's ATP > P > P > P, next minute it's ADP and CP, next hour it's PC and CP..

everyone ask your questions here, makes it easier for everyone :)
Ok resynthesis of ATP:
- ATP consists of adenosine and three phosphate molecules
- When the last phosphate molecule breaks off you get ADP, Pi (which is inorganic phosphate) and the energy produced when this phosphate molecule breaks off
- Thus to make more energy the ADP must then reconnect with another phosphate molecule so it can break off again and produce more energy
- The synthesis of this last phosphate molecule can come directly from PC (phosphocreatine) or from otehr food sources such as carb, fats, protein
Does this make sense?

Right,
so when one of the three inorganic phosphate groups fall off, then ATP is converted to ADP and Pi?

Yes correct
ADP - adenosine diphosphate
Pi - inorganic phosphate (the phosphate that has broken off)
The energy that is created for muscular contractions comes from this breaking of, thats as much detail as you need to know :)

Thanks.. my initial thought about AOS2 was "f*** this", because my P.E class is full of biology students, who are lucky enough to be studying energy systems right now, in depth..
starting to pickup on this stuff now.. :P

Yeah they do have a slight advanatge.
I did bio as well and I remember when others would be like "but why does __________ this occur" and I would know because I have done bio but that level of detail isnt needed in pe so teachers dont go into it. This extra knowledge isnt needed but may help you understand it better.
Just make sure you get a good understanding of energy systems because if you dont you will be screwed for the rest of unit 3 and AOS1 of unit 4 :P

Yeah btw did you do a practical report?
We're doing;
SAC1 = Written test (20 marks)
SAC2 = Practical report (30 marks) < can't imagine it being too hard at all, we did some practical sessions measuring how fast we can run in 5 seconds multiple times, multiple 50m sprints and a beep test. (we're pretty much just doing a prac report on that)

Nah never did a prac report, we actually hardly ever did actually pracs lol.
So sorry cant help you there :)

Thank-you for your help! I think my SAC is next week? I forgot what date. Haha. I'll try and write up a table for each of those points! :)

So can someone confirm this.
ATP-PC system:
- Uses PC and and muscular stores of ATP to produce energy.
Anaerobic gloycolysis system:
Anaerobic glcolysis system is fueled by Glycogen, which is broken down to Glucose and broken down to pyruvic acid. Although if there is no energy present then it is broken down to lactic acid which dissociates to lactate and hydrogen ions.
Aerobic energy system (carbohydrates):
Aerobic system is fueled by Glycogen, which is broken down to Glucose, which is then produced to Acetyl coenzyme A and broken down into the Krebs Cycle and then the electron transport chain.
Geez my book is crappy, only has diagrams..

ATP-pc system is correct
In the anaerobic system it's because there is no oxygen not energy that causes pyric acid to be broken into lactate and hydrogen acids
Aerobic system is correct but don't need to know that level of detail that's more bio

What are the differences between maximal and sub-maximal exercise?
-
What are the differences between maximal and sub-maximal exercise?
Ok maximal exercise is done to exhausation, and can't be maintained for long periods of time. In terms of intensity it is 7 or more mets and in terms of heart rate intensity it is 95%+ of your maximal heart rate.
Therefore submaximal intensity is when the athlete is working at a steady pace which can be maintained for long periods of time. In terms of mets it is anywhere between 3 to 6. In terms of a heart rate intensity it is around 65% to 85% of your max heart rate based on the activity you are doing.

thanks for the response.
Can you clarify if this table represents the responses in chronological order or random?

dont entirely understand what your question is
If by order you mean the order they happen, they are generally happen at the same time except the muscular repsonses.
For example at the start of exercise cardiac output, venous returen, diffusion, ventilation, oxygen consumption, blood pressure will all increase. However the energy substrate won't decrease as soon as exercise, when it will will depend on the intensity of the activity, its duration and the type of training done by the athlete.
Hope that makes sense

Hello,
Is the food fuel for the Anaerobic Glycolysis system carbohydrates, glucose or glycogen?

carbohydrates
it is stored as glycogen and is released as glucose ! (glucose is a carb)

Thanks I knew it was carbohydrates however my P.E teacher marked it as incorrect and told me it was Glucose!! (only practice questions) My P.E teacher seriously doesn't know the content himself! lol.

We should wait for one of the proffesionals but I hope I'm right
Also do we need to know about electron transport chain and Krebs cycle
-
Hello,
Is the food fuel for the Anaerobic Glycolysis system carbohydrates, glucose or glycogen?
Food fuel - the substance thats is actually used to make ATP - glucose, amino acids, free fatty acids
Food source - where the fuel comes from, what we actually eat - carbs, fat and protein
We should wait for one of the proffesionals but I hope I'm right
Also do we need to know about electron transport chain and Krebs cycle
Nah you don't, thats in bio course.

My teacher said that there might be Krebs cycle, Acetyl Coenzyme A and Electron Transport Chain questions on the SAC - ridiculous?
Also, I reviewed my SAC again today, and a question was:
7. Outline the NPAG for a child.
I answered it completely, although didn't include "5-12 years old" so he gave me no marks? I assumed I didn't have to present that information in my response because it wasn't really asked.
Also, would "Extending the amount of lunch time" be a suitable response for a strategy for a primary school to increase physical activity levels? Please be brutally honest? :p

very ridicolous, it is mentioned in the book that these stages happen but thats it. No info about what happens. Look if he says it maybe in the sac study it but it wont be in the exam.
Your teacher seems to be very harsh/tight/stupid. You shouldn't have to write the ages. To be honest in that question i would have also added 2-5 year olds as they are children as well, if we are being technical like him.
I wouldn't accept extending amount of lunch time by itself, i would expand on it. Link it to one of the levels of the socio-ecological model. You can see that it could target the social environment because it gives children more of a chance to interact with others and be more active.
There are a couple of easier examples you could use.

Thank you for the response. Yup it is ridiculous and my teacher is extremely slack it's ridiculous I can't get over it. The best I can do is to just study harder. Also, I agree with both of your responses. The first one surely was correct, although the extended lunch time answer I do believe was very vulnerable to his extremely subjective marking but I had no other ideas. It wasn't a socio-ecological model question, it was an "identify" question.
All I can do is just study harder :D

If he gave you a zero for not including one bit of information (that doesn't even seem relevant to the question tbh) then that's just not fair. Maybe you should talk to another PE teacher about this and ask their opinion on it?

No other P.E teachers unfortunately.

What would cause blood lactate levels to decrease at the beginning of a test?
Where is this question from ?
-
Why does the trained athlete have a lower cardiac output at sub-maximal levels than the untrained individual?
-
Why does the trained athlete have a lower cardiac output at sub-maximal levels than the untrained individual?
The trained athlete has a greater strike volume which means they can pump out more blood per beat compared to the untrained athlete. As a result during submaximal activities the trained athlete will be able to pump their heart less times than the untrained athlete to pump the same amount of blood around the body.
Eg
Untrained may need to pump 10 times to transport 1L of blood
The trained may only need 7 times to pump 1L
:)

thank you so much
another question
does the beep test rely on the atp-pc system?
-
The beep test (20m shuttle run) relies on the aerobic energy system. Remember that the beep test goes on for around like 5-15 minutes on average, around that.

when discussing energy system interplay would you talk about the atp-pc system? (other than 'all the systems are activated at the onset of exercise")

Of course. Interplay is where all three systems contribute, although one is predominant.

ok thanks but how would i talk about it because normally you would say for the first 10 seconds the atp-pc is dominant but is this the case with the beep test?
-
To be honest, I don't really know myself. We shalt wait for michak to come online lol.

Haha you guys are funny :) ok to answer your question
This is kinda like answering a interplay question on say a marathon so what I would do is answer it at different stages.
So at the start because of the very low intensity of the test aerobics system is dominant as we have another oxygen but other two are still contributing
Then later on as intensity gets higher the contributions from the two anaerobic systems will increase as you require short and fast bursts of energy
For example the ATP pc system may have the greatest contribution when sprinting to the line to making the beep and so on
With interplay questions just a couple of things:
1 don't always think that it will be the ATP of then anaerobic glycolysis then aerobic because what happens if they ask to discuss the interplay of just going for a walk?
2 remember all the systems are working at once the only thing that changes is the CONTRIBUTION they are making to the overall ATP production
3 don't be generic in you answers link it to specifc parts of the sport. So for example in footy say when they mark the ball or sprint towards a marking contest
4 though it may seem like you are repeating yourself always say that all the systems are always working at once. I made it a habit to say it at least three times so even though I am talking about one energy at a specific point the examiner knew I still know they are all working together
Hope that makes sense :)

Look whether it can be either i would just say they both increase their contribution and try to stay away from the word dominant. The sports given in VCAA exams are usually pretty good.
Yeah it would be the aerobic system. because it is low intensity and you have enough oxygen. You don't need atp produced instantaneous or that fast so why waste the pc?
But if that slow pace walk turns into a sprint the atp pc system will become dominant.
-
so it starts of with aerobic being predominant then as intensity increases atp-pc for 10 seconds then anaerobic ?
-

Yeah look its a bit weird sometimes you just need to be smart about it.
Just sometimes think about it logically - does it makes sense based off the charateristics for the atp-pc system to be dominant?
At the start of a 100m race - yes
Going for a walk - no
Ask your teacher to see what they say.

Yeah look its a bit weird sometimes you just need to be smart about it.

Yeah makes sense.
If you want a good example try the interplay question from the VCAA exam from 2009, it was on surfing.
It is a very good example.
If you want you can write an answer and I would be happy to look over it for you.
Just a remember a lot of people didnt do very well on this question.
Give it a go :)
