Changes in Heart Rate[edit | edit source]
As we age, one of the most notable changes in the cardiac system is the decline in maximum heart rate.
- One of the common means of establishing a guideline for change in maximum heart rate is the following formula:
220 - age = max heart rate
Therefore whereas a young adult of 20 can be expected to have a maximum heart rate of 200 bpm (beats per minute), a 70 year old will have a maximum heart rate of only 150 bpm, an 80 year old 140bpm and a 90 year old 130 bpm.
Consequences of reduction in maximum heart rate[edit | edit source]
- Smaller aerobic workload possible - ie. reduction in the extent of cardiac exertion that can be tolerated for a period of time
- Slower aerobic performance - eg. 90 year olds completing the New York City marathon typically do so in 7-8 hours
