What happens to your pulse after exercise?

Pulse recovery

A student rested, then stepped in place for two minutes. Their pulse before exercise was 76 beats per minute. The table shows one trial after exercise.

Teaching example with simulated data. These are not measurements from a real student.

Check your reasoning after you submit

The pulse falls from 138 to 80 beats per minute over four minutes, moving toward the resting rate of 76. Time after exercise is the independent variable on the x-axis. Pulse rate is the dependent variable on the y-axis. One trial from one person is not enough to claim the same pattern for everyone. Repeated trials with more people would make that claim stronger.
