awesome guys thanks.
it doesn't appear that hard either 
i quite like the content of area of study 2 in unit 3, sounds interesting. the rest is a little 'meh' but it's nothing too bad.
Definately agree, our class just covered chapter one, and will be moving on to chapter two next week. Can't wait till we get into the types of energy systems, or Food fuels, you know the interesting stuff 
our class just finished chapter one too:) i'm a little behind though because i didn't do the holiday homework nor 1/2, so i'll catch up this weekend. it just seems like most of pe is just all memorising things.. (and some data analysis)... which is pretty good haha!
yeah exactly that'll be good- can't wait to get past this dry topic of 'promotion of physical activity.'
Yeah true, personally didn't find NPAG's all that entertaining either, just a matter of memorising a crap load of figures really. 'In 1999-2000 studys were shown at 57% of people engaged in sufficient physical activity, showing a decrease in participation from the 62% who engaged during 1997'... blah blah blah 
yeah we have to go through these and summarise them this weekend. looks annoying.
i found someone's notes and all they had for the trends that we need to know are
Trends in PA
- Higher in summer than winter
- Higher in boys
- Higher education = more PA
- 1999 the most active subgroup was 18-29 yr olds
- 1999 the last active subgroup was 45-59 yr olds
- Large decline in 1999
is this not enough?
Looks fairly descent, to ensure top marks, I have memorised all details, from the adults, adolescent and childhood participation rates which include;
Adult;
- 1999-2000 clinical studies showed that 57% of the Austrlaian population were engaging in sufficient physical activity, which was a decrease from the 62% which participated in 1997 (Like I said above)
- Through these findings this also found that there was an increase in inactivity raising from 13% to 15% from 1997 to 1999-2000
- The most active subgroup were aged between 18-29
- The least active subgroup were aged between 45-59, with roughly 50% being sufficiently active
- Studies also showed that men (60%) were more active than women (54%), although men had the biggest decline during this period
Adolescents;
- It was found that 23% of adolescent teenagers didn’t participate in physical activity
- From the proportion that did participate, 51% of them were involved in moderate-intensity physical activity
- Adequate participation was defined as 3.5 hours of moderate-intensity physical activity over 5 sessions in a week.
- Vigorous - intensity was defined as 3 sessions a week for 20 minutes
- It was found that boys and girls are more active in summer months - This could be due to school holidays, and the enjoyment of being in the sun
- It was found that having a higher education lead to a higher participation in sport
Children;
- During 2003, 1.6 million participated in organised sport outside of school hours, with boys having a larger participation rate than girls
- 5-6 yr olds would average 4 hours a day of physical activity
- 10-12 yr olds would average 2 hours a day of physical activity
- 25% of 10-12 yr olds participated in 40 minutes of vigorous activity a day, with the least active group managing less than 10 minutes per day
