Revise: Investigating Exercise, Pulse Rate and RecoveryCounting these pulses gives the pulse rate, measured in beats per minute. Exercise usually increases pulse rate: working muscles need more energy from respiration, and increased blood flow helps supply the oxygen they need.
Describe how pulse rate is measured, rather than just writing ‘measure the pulse’. Include the counting time and units.
Measure each participant’s resting pulse rate: recovery does not mean reaching a universal value such as 60 beats per minute.
