(b) Read Jamila’s notes carefully.
I started with gentle exercise and measured my heart rate
in beats per minute.
My power was 70 watts and my heart rate was 80.
Then I pedalled faster, my heart rate reached 100 and my
power went to 120.
When my power was 170, my heart rate was 120.
I pedalled harder up to 220 watts and my heart rate was 140.
When I worked my hardest, the readings were 270 watts
and 160 beats per minute.
