Is your textbook Nelson? If so, it doesn't list the NPAGs properly.
All you really need to know are the 4 guidelines:
1. Think of movement as an opportunity, not an inconvenience.
2. Be active every day, in as many ways as you can.
3. Try to put together 30 minutes of moderate intensity physical activity on most, preferably all days of the week.
4. If you can, try and do some vigorous physical activity for extra health and fitness.
Also what you'll need to know are the individual guidelines for children, adults, the elderly, and overweight people.
Children:
1. Should do at least 60 minutes of physical activity every day, of all intensities, including a range of activities.
2. Should spend no more than 2 hours per day using electronic devices (except for homework).
Adults:
30 minutes a day of moderate intensity physical activity.
Elderly:
As above, but should also include weight and balance training, to improve balance and mobility.
Overweight:
60 minutes of moderate intensity physical activity per day, and 60-90 minutes a day after weight has been lost, in order to prevent weight regain.
That should do as far as knowledge of the NPAGs is concerned. Let me know if I've made a mistake or left something out, it has been a year since I've done this stuff!
