What does PEAK HEART RATE mean?(5 posts)

What does PEAK HEART RATE mean?joekm

Is it the maximum sustatinable heart rate or the maximum heart rate you should allow yourself?

Using 220 - age, I get 183 (i.e. I'm 37). Doing an interval test on the rollers that I'd read about somewhere on the net, I came up with 185. Lately, when I do runs for peak average speed on my lunchtime circuit, I've been peaking at 187 bpm.

Should I be concerned about the 187 or should I make that my maximum heart rate?

Thx :)

Peak is just that - a peak or a spike - not the plateau. I'm 40 and have hit 190 and lived to tell the tail.

Your max (peak)HR rate by itself tells you nothing about your fitness. It correlates with abosultely nothing. In other words while all world class cyclists have VO2's above 75 and resting hr below 50 - there max hr's are all over the place.

What it is useful for is if you get it measured in a lab or an your own, while you are in a very trained condition, you can then take percentages of your max HR and use them to guide your training. For example, for most people, somewhere between 85% and 90% of max hr is likely where your Lactate (anaerobic) threshold is. So if you know your max attainable hr is 200 then when you set out to keep your hr above 80% max for 30 minutes you know where to keep it.

I would always use whatever actual max you got to as your max HR #.

MAX heart rate must be measuredKerry

Presumably the PEAK you refer to is what nearly everyone calls the MAX heart rate. You cannot determine it from a formula - that is just a round number that doesn't consider your genetics or level of fitness. The reall way to measure it is to increase effort every minute in a controlled fashion until you simply cannot go any harder - that is your max. People often hit their max in an all out sprint or in a super hard hill climbing effort for a long hill. Your max is your max, and you don't need to worry about hitting it unless you have heart problems. Forget the formula.
the 220 rule is quite general. with 2 standard dev. from theC-mond

mean you are looking at a range of like 13 above or below that 220-age. It is better than nothing though
