Hey guys,
can anyone explain to me the three energy systems?
How they work and interrelate to one another?

Hi...
This is a fairly large part of the syllabus for Factors Affecting Performance, so I suggest you head over to the notes section or seek some other online resources if you are pretty unsure about the systems...
But here's a quick summary:
ATP/CP System: (alactacid system) Is an anaerobic system that depends on stored ATP within the body as the fuel source. It only lasts for a short period of time - around 5-8 second of maximum intensity - and usually is one quick, powerful movement. E.g. an attempt at long jump, springboard diving. After this time period, creatine phosphate (CP) for ATP re-synthesis is depleted, so the system needs to recover before it is effective again.
Lactic Acid System: Is an anaerobic system that depends on the break down of carbohydrates in blood glucose as the fuel to produce ATP. It can last between 30 second - 3 minutes, depending on the intensity of the exercise. E.g. a 400m athletics race, one round of a boxing match. Fatigue is caused by the build up of acidic molecules from lactic acid - a byproduct of the conversion of the carbohydrates to ATP.
Aerobic system: Is aerobic - requires oxygen to function - that uses the conversion of carbohydrates, fats and proteins into ATP to provide sustained energy for a long period of time: 1 - several hours, depending on intensity level. E.g. a marathon, tennis. Fatigue is caused by the depletion of carbohydrates, because after this, fats and proteins will be converted to energy, but these processes require a lot more oxygen.
These systems are interrelated, as each of them may be used in the one form of physical activity. For example, in a 200m running race (typically takes around 20-40 seconds), the initial alactacid system will be used until creatine phosphate is depleted, and then the lactic acid system will take over to provide the rest of the energy of the race. Overall, the systems work together to ensure the body has energy for the tasks it needs to complete.
Hope this helps! :D

Hey guys,
Can someone please explain what the physiological adaptations are briefly,
& how can they be related to the principles of training?
Thanks so much, in advance.

Hi...
I realise that this is over a month late (sorry!) but hopefully this may still be of use to you...
So the phyisological adaptations the syllabus wants you to focus on are: resting heart rate, stroke volume, cardiac output, lung capacity, oxygen uptake, muscle hypertrophy, haemoglobin level, effect on slow twitch/fast twitch muscle fibres
Which I like to remember in the acronym: Red Strawberries Create Lovely Odours May Harvest Evenings (yeah, a bit random, I know ;)).
Resting heart rate - measured in beats per minute, the amount of times the heart muscle contracts in one minute
Stroke volume - measured in ml, the amount of blood ejected from the left ventricle during one contraction
Cardiac output - measured in L/minute, the amount of blood ejected from the left ventricle during one mintue
Lung capacity - encompasses a few different measurements, focusing on how much air fits into the lung cavity though this is not really affected by training, more of a genetic/personal feature
Oxygen uptake - the efficiency of the body to absorb and transport oxygen to be used in the body's cells (often measured with VO2 Max)
Muscle Hypertrophy - the increase in the length/size of a cross section of a muscle (often visibly noticeable)
Haemoglobin Level - measured in g/dL, the concentration of the oxygen-binding protein haemoglobin in the blood.
Slow-Twitch/Fast-Twitch muscle fibres - includes a number of factors, such as slow/fast composition (determined largely by heredity), capillary efficiency, quantity of mitochondria, aerobic enzymes, myoglobin protein
Simply speaking, these adaptations are enhanced by the utilisation of the principles of training. The principles maximise the physiological gains by allowing an athlete's body to slowly become accustomed to the level of training, before it requires more alterations to boost the adaptations further (progressive overload). :)

Heyy everyone;
I was just wondering, for Core One for the syllabus dot points that list the 'groups experiencing health inequities', do I have to know them all and just two in detail or do I just pick the ATSI and any one of my choice?
Also, same question for the 'chronic diseases' section, do I choose one from the list alongside CVD or do I have to know two in detail and the rest just briefly?
Thanks so muchh!!

Hi...
For groups experiencing health inequities, probably just focus on two, one of which will be ATSI, like you have said.
For chronic diseases, you actually need to know three: CVD, cancer and one other. :)

Thankyou so much!

when was the pdh syllabus last updated?
Thanks in advance ;)
-
when was the pdh syllabus last updated?
Thanks in advance ;)
Last update was 2012, only to change DRABCD to DRSABC, lol! ;D
If this is for the purpose of past papers, basically any year from 2001 should be equivalent to the current syllabus. They have only made very minor changes since then. :)

Hey guys,
Does anyone have acronyms to remember the syllabus for The Healt of Young People?
I am especially struggling on the developmental aspects that affect the health of young people.
Thank you!

Hi...
Haven't come across at this stage, because it is a less-common option.
Have you tried to come up with some yourself? Acronyms are definitely more memorable if you make them relatable to your own interests and mindset. :)

I been stuggling to come up with some, so it's proabably easier to just memorise it.
I find this option to be so much content and very conceptual.. nothing like Sports Med at all!
But thank you for replying :)

Can someone please help me?, What are any specific health promotions that are aimed at reducing the health inequities suffered by the Socio-Economically Disadvantaged people?

Can someone please help me?, What are any specific health promotions that are aimed at reducing the health inequities suffered by the Socio-Economically Disadvantaged people?
Hi...
There arent many health initiatives aimed specifically at low SES people, but many address the access barriers to health services from low income. A few I can think of:
- Active Kids Rebate
- Pharmaceutical Benefits Scheme (subsidising medicine)
- Free childhood immunisation.
- Medicare system (allowing free access to public health services).
- Free sexual health & family planning clinics.
- Child Dental Benefits schedule.
Hope this gives you a few ideas. :)

Hey also i just wanted to ask if i am talking about a health promotion, and in the question it asks me to analyse and assess the effectiveness of the health promotion, can you just please tell me in dot points what i can include in my answer
thank you

Hi Guys sorry I have an assingment and I have this question to do. But I dont know how to start the response i chose the group People in rural and remote areas. If anyone could provide any ideas, starting points or general advice it would be greatly appreciated.
Explain the roles of individuals, communities and governments in addressing the health inequities experienced by ONE group other than Aboriginal and Torres Strait Islander people. (7 marks)
Thank you

"Explain why continuous training above the anaerobic threshold would be detrimental to aerobic endurance?"
Hi so here's my thinking,
If you are constantly increasing your anaerobic threshold, you would get to a point where you can utilise your lactic or alactacid system for far longer than the 'standard' 15secs (ATP/PC system) or the 3-4mins (70% effort of the lactic acid system). This would be detrimental to aerobic endurance as you are utilised other systems for longer periods of time, which means that you won't be using your aerobic energy system as efficiently or even at all. Continuously training in above this threshold keeps almost pushing the point at which the aerobic system would kick in further away. (for lack of better explanation). This means that when perhaps you decide to go do some aerobic endurance based activity like a marathon run, you'll be fine for a little bit but when you actually start to utilise the aerobic system, you've trained only for anaerobic as your threshold kept becoming higher so you could never get into a state or time to train aerobically. Therefore, your endurance has been affected by this continuous training and creates further problems for other aerobic sports/activities.
Let me think of an example:
Let's say you are a professional sprinter - 400m (that weird in-between sprint and jog phase) and you want to be able to sprint the entirety of that race, you are going to train to increase your anaerobic threshold. Okay that's great, but now you decide you would like to enter in longer races such as the 800m or the 1500m. Your body is so used to (and really good at- efficient) using those anaerobic systems that once your aerobic system clocks in, you'll dramatically see a drop in performance. Even if you did try and train aerobically, due to your threshold being so high, you might not be even reaching the state to be training aerobically - and rather still training mainly on your lactic acid system.
Look, this is what I would do to answer that question, not 100% sure but I hoped it helps??

Hii everyone,
Does anyone know good links or resources to find good pdhpe trial papers with answers?
Thanks so much.
Best bet is to go through the NESA website and print off some past papers to trial.
Or these are good:

hello
i need help with this question
have you got any ideas?
Analyse the factors that influence changes in physiological responses during and after participation in rugby. Consider:
The
Heart rate
Ventilation rate
Stroke volume
Cardiac output
Lactate levels
The easiest way to attack this question is to break it down. So obviously you have the 5 physiological responses to consider, but you also have to consider what happens to those responses during and after the sport. All those dot points are the "factors that influence change" - you just have to analyse them from during and after.
The verb used is ANALYSE: so you need to identify components and the relationships between them or draw out and relate implications. E.g. obviously during the game, heart rate will be significantly higher than after.
I personally don't know enough about rugby to personalise my response to this question but I'll just give a broad explanation and then you can edit it?
Heart rate is the number of times your heart beats in a minute. Heart rate responds to training by increasing from the resting value and is often used to set or determine the intensity of the training session. Heart rate increases during exercise as more oxygen is required by the muscles to continuously move and get rid of CO2. Obviously, this connects the respiratory system as it takes in more oxygen for the body and removed the waste product of CO2. The heart rate needs to increase to more efficiently and quickly remove waste from the body and bring more oxygen for the muscles. This increase in heart rate occurs as the body needs to be able to deliver oxygen at the required rate of muscles and remove CO2 as well.
Once the activity has ceased, the heart rate will drop and return to normal as there is no requirement from the muscles or the body for increased levels of oxygen intake or getting rid of CO2.
Go through each of the points like this (in more depth and alter it to fit rugby) and you should be sweet. If you need any more help, direct message me :)

This is a question regarding HSC Core 2: Factors Affecting Performance
What would be the best type of of feedback that could be best utilised by a performer to develop the skill of dribbling for soccer? Would it be internal, part, concurrent, or delayed?
