🏃‍♂️ Part 1: Exercise Testing Protocol

Success Criteria: I can accurately measure breathing rate and heart rate before and after exercise

Equipment needed: Stopwatch, clipboard, pen

Step-by-Step Instructions:

1. Resting Measurements (5 minutes rest first):

• Count breaths for 15 seconds, multiply by 4 = breathing rate per minute

• Find pulse at wrist or neck, count for 15 seconds, multiply by 4 = heart rate per minute

2. Exercise 1 - Skipping (200 skips):

• Perform 200 skips continuously. Measure breathing rate and heart rate immediately after completing the skips.

3. Rest for 3 minutes, then Exercise 2 - Jogging on spot (3 minutes):

• Jog in place for 3 minutes. Measure breathing rate and heart rate immediately after jogging.

4. Rest for 3 minutes, then Exercise 3 - The Bronco (netball court) as fast as possible:

• Set up cones at designated distances. Sprint to the first cone and back, then to the second cone and back, and finally to the third cone and back. Measure breathing rate and heart rate immediately after completing the exercise.

1. Record your group's data in the table below:

Condition	Student 1 Breathing Rate (breaths/min)	Student 1 Heart Rate (beats/min)	Student 2 Breathing Rate (breaths/min)	Student 2 Heart Rate (beats/min)
Resting
After Skipping
After Jogging
After The Bronco

📊 Part 2: Data Analysis

Success Criteria: I can analyse and compare breathing rate and heart rate changes during different exercises

2. Which exercise caused the greatest increase in heart rate? Why do you think this happened?

3. Compare the breathing rate and heart rate changes. Which changed more dramatically?

Breathing rate changed more

Heart rate changed more

They changed about the same amount

4. Calculate the percentage increase from resting to your highest heart rate reading:

Formula: ((Highest rate - Resting rate) ÷ Resting rate) × 100 = ______ %

5. Why do you think breathing rate and heart rate both increase during exercise?

🎯 Part 3: Reflection & Extension

6. How might an athlete's results differ from yours? Explain your reasoning.

7. Extension Activity: Design your own exercise test using equipment available in the gym. Describe the exercise and predict the physiological response:

8. Differentiation Support: If you found measuring difficult, what strategies could help you be more accurate next time?

Use a longer counting period (30 seconds instead of 15)

Have a partner help count

Practice finding pulse points before starting

Use technology (heart rate monitor) if available

Research Extension: Investigate how altitude, temperature, or fitness level affects heart rate during exercise. Present your findings to the class next lesson.
