A student investigated how different intensities of cycling affected their heart rate.

The student measured their radial pulse on their wrist, as shown in the diagram, by counting the number of beats in 15 seconds.

A line drawing of a wrist showing two fingers of the opposite hand placed near the base of the thumb over the radial artery pulse point.

This measurement was used to calculate the heart rate in beats per minute.
