A student investigated recovery heart rate patterns after a 3-minute step test in their aerobic training study.
Which method would be most appropriate for presenting the findings to show how heart rate changes during the 10-minute recovery period?
- A pie chart showing the percentage of time spent in different heart rate zones
- A line graph plotting heart rate measurements against time during recovery
- A bar graph comparing the highest heart rate reached by each participant
- A table listing each participant's name alongside their final recovery heart rate
