The normal pulse rate range for all adults, including women who are over 50 years old, is 60 to 100 beats per minute, as stated by Cleveland Clinic. Women who are active or exercising might notice an increase in their heart rate.
When a person exercises, the body requires an increase in oxygen-rich blood. The heart must beat faster to meet that requirement. For that reason, taking a pulse during exercise or physical activity might not yield a result that is within the average range. Additionally, a woman who is on beta blockers might have a lower heart rate, while a heavier woman might have a higher heart rate.
