## A. Prior to the lesson:

1. Arrange students into groups. Each group needs at least ONE person who has a mobile device.

2. If their phone camera doesn't automatically detect and decode QR codes, ask students to

• Bring these devices into the lesson.

4. Cut them out and place them around your class / school.

## B. The lesson:

1. Give each group a clipboard and a piece of paper so they can write down the decoded questions and their answers to them.

2. Explain to the students that the codes are hidden around the school. Each team will get ONE point for each question they correctly decode and copy down onto their sheet, and a further TWO points if they can then provide the correct answer and write this down underneath the question.

3. Away they go! The winner is the first team to return with the most correct answers in the time available. This could be within a lesson, or during a lunchbreak, or even over several days!

## C. TIPS / OTHER IDEAS

4. A detailed case study in how to set up a successful QR Scavenger Hunt using this tool can be found here.

### Question

1. How long does PC as a fuel generate energy for via the ATP-PC system at maximal intensity?10sec
2. State how much ATP (yield)is produced by each energy systemATP-PC 0.7-ANAEROBIC G 2-3-AEROBIC G 38 AEROBIC LIP 441
3. What intensity [% VO2 max]does LIP occur for a trained and untrained individual? 55-70% and 75-90%
4. During maximal intensity activity, at what time period would an equal, 50:50 contribution from the aerobic and anaerobic systems occur?75sec
5. Name 3 factors that affect the muscular strength of an athletecrosssectional area-gender-sex-speed of contration-fibre type
6. Name three ways the body promotes venous return during exercisemuscle pump-respiratory pump and venoconstriction
7. When would protein provide a fuel for aerobic glycolysisnever, its aerobic proteolysis
8. Name 3 variables that dictate what energy system is contributing during exercise?intensity-duration-whether o2 is present
9. Name 6 health related fitness componentsflexibility-aerobic capacity-muscular endurance-muscular strength-body composition
10. Name 6 skill related fitness componentsagility-muscular power-anaerobic capacity-speed-reaction time-balance
11. Low GI foods and High GI foods are given what ranking number/s?<55 and above 70
12. Name 4 dimensions of Physical Activityfrequency-intensity-duration-type
13. At rest we are expending 1 MET. This is the equivalent to how much oxygen being consumed per minute? 200-250mL
14. Name 3 ways we can measure Physical activity guideline compliance. accelerometer-direct observation-recall diaries
15. Explain what reciprocal causation is and provide an example. lack of access to facilities can limit the number of people who are able to undertake activity (environment influencing behaviour)
16. Name 2 acute respiratory responses to exercise.Increased ventilation-increased diffusion
17. Name 3 byproducts of aerobic glycolysis.CO2-heat-water
18. Name 3 metabolic byproducts that can accumulate and contribute to fatigue.ADP-Pi and H+
19. Name 2 factors that contribute to neuromuscular fatigue.Ach neurotransmitter slows down messages-decreased CNS firing rate or impaired sodium/potassium pump
20. With passive recovery, what % of PC can be replenished in 3mins?70%
21. Name the 3 chronic adaptations that lead to an increased LIP.increased mitochondrial density-increased oxidation of fat and glycogen
22. Most improvement you can get in your LIP occur after how many weeks of training?8-12
23. What 2 variables are used to calculate VO2 max?avo2 diff and Q
24. Name 2 tests, other than the shuttle run test, that can be used to assess aerobic capacity.VO2 max test and 1.6km run
25. Write down the formula to work out BMI, including units of measurement.weight (kg)/height (m2)
26. What is the immediate resulting product of the glycolysis process (both aerobic and anaerobic)?Pyruvic acid
