Application Exercises The maximum heart rate, in beats per minute, that yon should achieve during exercise is 220 minus your age: 220 - a. This algebraic expression gives maximum heart rate in terms of age, a. The following bar graph shows the target heart rate ranges for four types of exercise goals. The lower and upper limits of these ranges a re fractions of the maximum heart rate, 220 - a. Exercises 129 -130 are based on the information in the graph. If your exercise goal is to improve overall health, the graph shows the following range for target heart rate, H , in beats per minute: Lower limit of range H = 1 2 ( 220 − a ) Upper limit of range H = 3 5 ( 220 − a ) . a. What is the lower limit of the heart rate range, in beats per minute, for a 30-year-old with this exercise goal? b. What is the upper limit of the heart rate range, in beats per minute, for a 30-year-old with this exercise goal?

Solution Summary: The author explains that the lower limit of heart rate during exercise for a 30-year-old is 95 beats per minute.
The maximum heart rate, in beats per minute, that yon should achieve during exercise is 220 minus your age:
220 - a.
This algebraic expression gives maximum heart rate in terms of age, a.
The following bar graph shows the target heart rate ranges for four types of exercise goals. The lower and upper limits of these ranges are fractions of the maximum heart rate, 220 - a. Exercises 129-130 are based on the information in the graph.
