Maximum Heart Rates
According to the American Heart
Association, a person’s
maximum heart rate is as listed
in the table. Traditionally, a
person should exercise in such a
way that his or her heart rate
stays between 50% and 75% of
the maximum heart rate. This is
called the target heart rate.
Age
Average Maximum
Heart Rate
20 years 200 beats per minute
25 years 195 beats per minute
30 years 190 beats per minute
35 years 185 beats per minute
40 years 180 beats per minute
1. Find an equation to represent 45 years 175 beats per minute
the relationship between a
50 years 170 beats per minute
person’s age and their maximum 55 years 165 beats per minute
heart rate.
60 years 160 beats per minute
65 years 155 beats per minute
70 years 150 beats per minute
2. Find equations to represent the lower and upper bounds of the
target heart rate.
3. Predict a maximum heart rate of someone who is
a) 22 years old
b) 58 years old
4. Predict the target heart rates of someone who is
a) 22 years old
b) 58 years old
