Heartrate variability...

asked 4 months ago | Report

I have a question that´s been bothering me for quite some time now:
What does it mean when my resting HR is 45, but my max HR is 205? Is that good, bad, healthy or even dangerous?
To clarify myself: I am 30years old, I have been a goalkeeper for about 12years, until about 7years ago when an injury forced me to retire. Ever since then I have kept running, first shorter distances and since last year I take on ultra marathons quite regularly, about 6 races per year.
And what I discovered pretty early on was that my heart rate during training easily reaches 170 bpm while my training partners barely reach 150 bpm. At times when the pace/ascending rate is right my hearts beats well over 200 time per minute.
I feel fine with it but I sometimes wonder why that is...? It can´t be measuring error because over the years I have tried 4 different sports watches, each of them showed the same results. Even in the Gym on a treadmill doing an interval test the machine nearly panicked...

  • No one here can tell you for sure if you have a problem or not. With something as important as your heart get it checked by your doctor. Having said that we are all different and have different heart rates so probably nothing wrong. With your exercise history you sound to be very fit. but get it checked out to be sure.

  • I know everyone's resting and max can vary greatly. Your resting being so low normally would indicate you are in pretty good shape (aerobically speaking). Not sure about the max. If you haven't had your heart rate zones tested I would start there. They do it at my gym and the amount of information you get from it really is fascinating. If you have already gone that route, maybe have a stress test done by a doctor if it seems to be abnormally high?

    I know I have seen other people's zone charts who have a similar fitness level as me and the rates are significantly different from mine too. If it were me, I probably would just chalk it up to individual differences unless I felt like I was getting up to 205 and hitting a wall or having to stop to catch my breath kind of thing.

  • Well Ben I dont have an answer to that. I know most professional athletes perform at very low heart rates. But I believe that comes with years of training.

    Im trying to lower my heart rate. One way of doing this is to train at a certain heart rate.

    McMillan's website explains it a little bit. : http://www.mcmillanrunning.com/index.php/articlePages/latest

    I cant find any good articles about HR Variably and HR Training.

  • Personally, I would have it checked. Your max generally sounds high for someone with a resting HR of 45. The golden rule is 220 - your age for max, putting you at 190. But even this is a guideline, not a hard and fast rule. Couldn't hurt to check it out.

  • My heart rate is pretty much identical to yours and there is nothing wrong with it - genetics play a large role in this but training can also effect your exercising heart rate. There are 2 ways that your heart can pump more blood:

    1) It can it can increase the # of beats per minute
    2) It can increase the amount of blood it pumps per beat (stroke volume). The best way to improve your stroke volume is through long, slow distance training.

    Most training programs are based on %of max HR. So rather than training based on your absolute number (ie 170), train based on what % of your max that is (ie 83%). If you notice that you are running at a high % of your max on your LSD runs then you want to slow that down. You can also run based on % HR reserve, which will be a little more accurate.

    Jack Daniels' has a great table in his book Daniels' Running Formula that describes what physiological changes are taking place at different training intensities.

  • I like Joanna F. explanation of HR Variability. Here is another site that has a simple explanation of HR Training.

  • The Karvonen method has been criticized greatly because it doesn't fit so many peoples heart rate. Have you ever checked out Lance Armstrongs heart rate numbers during training. Like you, he rested in the 40's and peaked in the 200's. If you're concerned, you can always have a cardiologist check you over. The low heart rate could be due to Athletes Heart Syndrome (common among endurance athletes), but if you feel perfectly fine, no vertigo, dizziness, lightheaded, or an irregular beat, your heart is doing it's job. An ECG or EKG can always help answer questions, but I'd would predict this is just your normal heart rate since you are not experiencing extreme fatigue, arrythmias, or any of the other negative side effects that go with an abnormal heartrate, Just remember not everyone fits in the box!

  • I bet that treadmill had no idea what to do with your HR!

    I'm actually getting ready to go through testing next week to determine heart rate zones for training. In the reading I've been doing it does seem that our max HR is genetically predetermined. It will be your max if you are lethargic or if you're active, but your ability to go longer distances at various HRs will change depending on the conditioning that you do. I strapped on my HR monitor last night to figure out where my low, resting is and I think when I finally get to hook up my watch and upload the data, I'm going to find that it's mid to high 40s. In all of my workouts, even when I'm pushing it, I hardly ever go over 178. The highest it's been without false reading I think has been around 188. Someone I know, however, runs about 210 when he's pushing his max.

    But definitely agree, if you're concerned, seek out a cardiologist.

  • I have been doing tons of research on HR training lately. My latest Max HR was 187. I'm 51 years old. Everybody's heart rates are different. Like a bell curve, most fall into a general formula. You and I don't. What this means - generally, is that we were born with smaller hearts. Our hearts have to work faster to do the job. The fact that you have such a low resting HR is a testament to your athletic work. It isn't dangerous, it's just genetics.

    I really liked what Joanna had to say. If you have availability to good sports doctors, this would be something to check out. You'd probably learn a lot, and you could make sure you don't have a plaque condition like my running neighbor who died this fall during a marathon.

  • I read that the max isn't 220 - age. You may be fine. Everyone is different. You could have it checked if you are really concerned.

  • I may be in opposition here, but I don’t believe we are all that different.
    I'm a big advocate of low heart rate training, so be warned :)

    Bit older (38), my resting and max HR are similar to yours (40 and 210).
    I used to train in 160-180 range, one hour race usually averaged at 190 with a finish sprint above 200.
    If you feel fine, it is probably ok, but my health become seriously damaged over time. Now I know I was guilty of training too hard too often, using “everyone is different” as an excuse to train hard. I become overtrained, my immune system was failing, I was sick big time.
    Searching for a solution I found this low heart rate, "build your aerobic base first" approach and have read everything I could find (Maffetone, Van Aaken, Lydiard, Mark Allen, Mittleman, Hadd...)
    I switched to this method a year ago and never looked back. I see huge improvements in both my health and my racing performance.

    My english is reaching its limits here, so I will end this with links I think are worth reading:
