Runners are often known to be obsessive about their pulse rate. For a runner the pulse rate is used for two things. The one that a runner will tell you about is that the pulse rate is used as a measure of the difficulty of a training run. The one not mentioned is used as an ego booster. The average resting pulse rate of a man is 72 beats per minute, for a woman the average resting pulse rate is 80 beats per minute. A fit male runner has a resting pulse rate in the low 50 beats per minute, a fit woman will be in the low 60 beats per minute. Some elite runners have resting pulse rates in the mid 30 beats per minute. Then to add "more than you want to know" to the low pulse rate, they mention that they have 79,200 beats per day (55 beats per minute) versus the sedentary person’s 103,680 beats per day. That means a fit runner has 24,480 beats less per day than the normal person. This means in one year, a runner has 8,935,200 beats less than a non-runner. While having a more efficient heart is good, the pulse rate is too often used as a bragging point.
Using the pulse rate as a measure of the difficulty of a training run is a little confusing as to which method of measuring is used. The standard method of 220 minus your age to determine your maximum pulse rate is not accurate for fit older runners. The recommended training scale is between 60% and 80% of that maximum. (An example, for instance, would be a 40-year-old runner using the formula 220 – 40 = 180 beats for a maximum pulse rate. A training pulse rate is between 108 and 144 beats). When I was 50 years old, my training pulse rate was supposed to be between 102 and 136 beats per minute. On a hard training run my pulse rate was 180 beats per minute. For a fit masters age runner, the average training pulse rate is much too low.
Alternate methods to determine a training pulse rate have been developed. The Mayo Clinic developed a formula for women over the age of 40. This method had women multiplying their age by 67% and subtract that number from 200 for a maximum heart rate. (Example: 45-year-old woman X .67 = 30.15. 200 – 30 = 170 for a maximum heart rate.) Men multiply their age by 93% and subtract that from 216. (Example: 45 year old man X .93 = 41.85 (42). 216 – 42 = 174 beats for a maximum heart rate.) This formula works better as a runner gets older. A 70-year-old runner has almost nine beats higher rate than using the standard method of 220 – age.
