6. An investigation was carried out to investigate a possible relationship between BMI (body mass in Kg/height in m2) and the increase in pulse rate on exercise. A group of 17-year-old pupils measured their BMI. Their resting pulse was then measured manually on their carotid artery by the experimenter. They walked on a treadmill at 4km/hr for 5 minutes and their exercise pulse was measured immediately. The percentage increase in pulse rate on exercise was calculated and plotted against BMI as shown in the graph below.
