What is your ARHR?

Don't be alarmed. A study of sinus bradycardia (pulse below 60/min.) in asymptomatic men published about 20 years ago in the American Journal of Cardiology found that although the bradycardic subjects were more likely than those with normal pulse (60-100) to develop other cardiac conduction abnormalities over the 5 year study period, they did not differ in mortality rate to a statistically significant degree.

in that case, mine is 64
 
Congradulations! An Italian study published in 1999 in a European journal suggested that as one gets older, a slow heart rate predisposes to congestive heart failure. I think some people have the notion that a slow heart rate is a good thing because athletic training seems to slow the rate for some, but that's not supported by a lot of the evidence. The average rate in healthy adults is 70/min. The very-elderly (over 85) do not tend to have slow heart rates.
 
WoW, 28 bpm? Did you hold your breath to slow the beats lol? That's insane I heard lance arm strong averages 30 bpm

No. That was the lowest I recorded on the machine before I gave plasma in college (yes, I was that poor). So, my waking heart rate could have been slightly lower. Typically I was either 30 or 32 bpm before the plasma thing. I had to walk around the room for a minute because they would not allow anyone with a heart rate below 50 to give plasma.

This guy I worked with this year said his lowest resting heart rate was 26 when he used to run. His bodyfat was so low the doctor insisted that he drink whole milk and eat icecream. He said his bodyfat was just below 3%. When I had mine tested at that time, I think it was 5%. Mind you, I thought that was terrible (because I longed to be a big guy in college).
 
My resting heart rate this a.m. was 45. I have a long history of endurance running and triathlon. I'm 66.

A low resting heart rate is indicative, to some extent, of one's fitness level, but it is often due to a superior VO2max and a large stroke volume. A person with a resting heart rate of 40 can die of cardiovascular disease just as easily as someone with a resting heart rate of 80. Which is why a Thallium Stress Test, or similar, to evaluate one's coronary arteries is important. I had this done at the VA, in part because they were concerned about my abnormal bradycardia at age 62. I was then around 40 bpm, as I was training for Ironman Florida. My Chinese cardiologist told me after the test: "Your colonary atries like fowr lane highway." So, my low resting heart rate is part genetic, part training and diet. It doesn't indicate I'm going to die soon from heart failure. I'm more likely to die of fright from one of my forehands....

I think body size is a factor as well. I was talking about this yesterday with a tennis buddy of mine who also happens to be a biology professor at the local collge. He's 6'6" and has a RHR in the low 40s. I think mine is in the high 50s. He says part of why his is so low is that his body is so big. Of course he also swims and/or runs/plays tennis every day.

Actually, it's the reverse. :)

Have you looked at marathoners, Tour de France riders, and most elite triathletes? They tend to be small and have very low resting heart rates and high VO2maxes.

Also, much of having a low resting heart rate is genetic, just as having a high native VO2max is genetic, mostly. (Your friend won part of the genetic lottery.) You can lower your resting heart rate with lots of endurance training, particularly if it's now in the 60's or 70's as most peoples'.

But, don't think having a low heart rate is that meaningful. If you have a low resting heart rate, but an otherwise irregular rhythm, high blood pressure, and arteries clogged tighter than a New York sewer, don't expect to live a long life. ;)

Diet, exercise, lowered stress, having loved ones in your life, picking great parents, and not making risky life choices (like driving that motorcyle 150 mph) are some of the keys to living a long life. With luck, you might get as old as me. ;)
