The new formula for women, based on the new research, is 206 minus 88 percent of age. At age 50, the original formula gives a peak rate of 170 beats per minute for men and women. The new women's formula gives a maximum heart rate of 162 beats for women. Many men and women use their peak heart rate multiplied by 65 to 85 percent to determine their upper heart rate when exercising.
THE FACTS. The normal resting heart rate for an adult ranges from 60 to 100 beats per minute. But some researchers believe it may be time to re-examine whatâs considered normal.Researchers have found that a resting pulse at the upper end of ânormalâ may indicate a higher risk of stroke and heart disease.he normal resting heart rate for an adult ranges from 60 to 100 beats per minute.
