The data presents the differences in pulse rates between two individuals of contrasting ages and professions. The graph displays two lines: one for Mabel, an office worker, who is 10 years older than the other person, Albert, a retired college athlete. The lines represent pulse rates per minute, with Mabel’s showing a more drastic change compared to Albert’s.
Starting at 0 minutes, Mabel’s heart rate is around 60 beats per minute, while Albert’s is exactly 80 beats per minute. Within the next minute, both pulse rates increase similarly, reaching around 80 beats per minute. Over the span of 2 minutes, the older individual’s pulse has risen to 150 beats per minute, while the younger gentleman’s pulse remains at 120 beats per minute.
Throughout the 120 seconds, both lines decrease; Mabel’s pulse rate hits just below 100 beats per minute, while the 26-year-old’s remains around 110 beats at the 60-second mark. In the final 60 seconds, unexpectedly, the former athlete’s line drops to 60 beats per minute, and the office worker’s line lowers to 80 beats per minute.
