PATHOLOGY

Detailed explanation-1: -First, subtract 45 from 220 to get 175-this is your maximum heart rate. Next, check your resting heart rate first thing in the morning. Multiply 95 by 0.7 (70%) to get 66.5, then add your resting heart rate of 80 to get 146.5. More items

Detailed explanation-2: -The maximum rate is based on your age, as subtracted from 220. So for a 50-year-old, maximum heart rate is 220 minus 50, or 170 beats per minute. At a 50 percent exertion level, your target would be 50 percent of that maximum, or 85 beats per minute.

Detailed explanation-3: -You can estimate your maximum heart rate based on your age. To estimate your maximum age-related heart rate, subtract your age from 220. For example, for a 50-year-old person, the estimated maximum age-related heart rate would be calculated as 220 – 50 years = 170 beats per minute (bpm).
