Exercise and Respiration Investigation
Method and results
Method: The pupil sat quietly for five minutes. They counted their pulse for 30 seconds and doubled the count to estimate beats per minute (bpm). They then did gentle step-ups for one minute, measured their pulse, repeated the step-ups for a second minute, and measured again. After stopping, they rested and measured their pulse five minutes later. These example results are provided for analysis.
