Apparatus: Two volunteers (Person A and Person B; you may also be Person A) Stopwatch (cell phone may also be used) Pen and paper Method: Ensure that both persons are at rest having done no physical activity for at least 10 minutes. Both persons’ heart rates are measured at rest and recorded in a table. Person A runs on the same spot for exactly 30 seconds, lifting their knees up high When Person A finished running for 30 seconds, Person B takes Person A’s pulse and records it in a table. Person A must then rest for one minute. Next, Person B runs on the same spot for exactly 30 seconds, lifting their knees up high. When Person B finished running for 30 seconds, Person A takes Person B’s pulse and records it in the table. Person B must then rest for one minute. Steps 2-7 is repeated with the running time increased to 60 seconds. Steps 2-7 is repeated with the running time increased to 90 seconds.
