Question

if 220 - age represents your max heart rate (100%) and your target heart rate is between 60% and 85% of your max, what is your target heart range if you are 16 years old. round to the nearest number.
a. ○ 100 and 210
b. ○ 160 and 190
c. ○ 122 and 173
d. ○ none of these
e. ○ 111 and 136

Explanation:

Step1: Calculate max heart rate

Max heart rate = 220 - age. Age is 16, so 220 - 16 = 204.

Step2: Calculate lower target rate (60% of max)

Lower rate = 0.6 * 204 = 122.4, rounded to 122.

Step3: Calculate upper target rate (85% of max)

Upper rate = 0.85 * 204 = 173.4, rounded to 173.

Answer:

C. 122 and 173
