Sample Answer
- Begin by identifying the specific aspect of recovery heart rate to be examined (rate of decline, time to return to baseline, or percentage recovery at set time points).
- Define the aerobic training stimulus precisely, including intensity (e.g., percentage of maximum heart rate) and duration of the exercise.
- Consider the timeframe for measuring recovery (immediate post-exercise and at what intervals thereafter).
- Ensure the question is measurable using available equipment such as heart rate monitors or pulse palpation techniques.
- Refine the question to be specific, clear, and focused on a single relationship rather than multiple variables, such as “How does a 15-minute run at 70% maximum heart rate affect the time taken for heart rate to return to within 10% of resting values?”
