Which of the following is the most appropriate method for presenting findings from a physiological investigation on heart rate recovery after aerobic training?

  1. A pie chart displaying participants' ages
  2. A line graph showing heart rate changes over time
  3. A list of individual participant names and their maximum heart rates
  4. A bar graph comparing average heart rates before and after training

Show Worked Solution

Consider Option B: A line graph showing heart rate changes over time

  • A line graph effectively shows changes over time, which is essential for displaying heart rate recovery patterns after aerobic training.

Other Options:

  • A is incorrect: A pie chart is suitable for showing proportions within a whole, not for displaying physiological changes over time.
  • C is incorrect: A list of names and maximum heart rates doesn’t visually represent patterns or relationships in the data.
  • D is incorrect: A bar graph is better for comparing discrete categories rather than continuous changes over time that occur during recovery.
