New max HR

I have the heart rate of a 23 year old!!

I hit a new max HR today ... 197 bpm. That surprised me because my previous high of 194 bpm is already quite a bit over that 220-age thing.

I felt a little fuzzy and my hands went numb, but other than that, I didn't really feel like I was working all that hard. However, on the next two attempts I only reached 195 bpm.


What's your max, and does it fit with that 200-age estimate?

Not even close to the formulas.. I have seen 205 on mine. I am 27.

Side note my morning resting rate ranges between 45 - 50.

I saw 184 on a ride Monday, and kept it up for about 3 miles. Definitely not max effort as I felt fine and continued to ride another 20 miles at 70%. I figure max has to be at least 190, and probably a bit more.

According to the formula, my MHR should be 170. I don't think that formula is much more than a rough estimate.

I'm 50 this year, and I will occasionally still hit 180-182 on a really steep climb on the mtn bike, the road bike will push it up to about 176-178. Most long-time runners and cyclists have a max HR that is considerably higher than that old 220-age rule. I have heard that a better number to use for athletes is 205 - 1/2 your age, which for me would be spot on at 180.

No, you have the heart rate of a 'however-old-you-are'-old. 220 minus age is ridiculously inaccurate and worthless, as are most other formulas . . . nor is max HR (by itself) a measure of fitness; it's determined largely by genetics and not changed significantly by workouts.

My max HR is 190 which by "the formula" would make me somewhat younger than I actually am if I took "the formula" seriously, which I don't.

Better measure of fitness is seeing % of max decrease given the same effort, or power increase given the same % of max. But not max by itself.

Well, I just took a V02 max test today and my max heart rate according to that was 203. I think I may have been able to hang on a tad longer, but it's certainly not much higher than that. I'm 21, so I guess I'm actually pretty darn close. Still, that just seems like a silly rule of thumb.

You all gotta remember that this rule of thumb was developed long before the personal HRM came about.
There was a time when these monitoring capabilities were restricted to labs with large, expensive equipment. Given the small base of testing before the great stuff we have now, the 'rule of thumb' isn't too far off.
And as stated, each person's HR will vary with genetic influence; as will the relative power and work that can be done at those heart rates. With a training athlete, Max HR will prolly be one of the least important benchmarks, given most will be in close proximity to each other.
Still it shows heart muscle conditioning.
I was at a low 162 max back in march when I was coming off almost 4 months of very low actiivty due to a serious mishap that broke a number of bones, collapsed my left lung and caused extensive lose of lung capacity on the left side. It has been a long road back, and soft tissue scans still show some unrecovered sections and scarring on the lung, but prognosis is good for recovering a lot of that as the lung continues to slowly heal.
Just bought a new HRM, I'll be very interested to see what I can hit now, after almost 6 mos. of determined and planned training. I guess I should spend the dosh and have a VO2 max test done also - just to know... or I can buy a nice set of wheelz instead and say 'knowing could be just a big disappointment'

Mashka, I thought that your favourite type of cycling is riding for a long time. Why are you going so hard?

Max heart rate achieved really depends on the individual. Imagine two individual with identical physiological characteristics except for heart volume and just for the sake of argument that both can put out the same amount of maximum power. Now obviously, the guy with the bigger heart is simply going to pump his heart less at maximum power.

The thing is for any individual, the larger and stronger the heart becomes with training, itís only going to beat less for a certain power output. If you have achieved a new high HR compared to before, you need to know also whether you have achieved a new high in power as well because HR can continue to rise without getting any gain in power.

Or you could find a university lab study where they pay you to take the test, and you can put that towards some wheels =). Actually though, I found that the wattage I got at V02 max was very similar to the kind of output I had already estimated from a pretty much full out 5 minute steepish hill climb. You can use hill climb calculators to find out estimated wattage. There are also tests to get approximate V02 numbers. Might not be worth the money if you have to pay for it, although it is kinda fun in a masochistic way, and it's fun to be hooked up to all that fancy equipment. The masochism must be part of why I like biking anyway...

I always find the formulas to be useless for any kind of conditioned person. I am taking Spinning for 3 credits (senior year schedule is sweet) this semester and we use heart rate monitors and the basic 220-age formula. My fatigue never matches what my teacher says it should be for the heart rate I am at so my max is obviously higher than that formula.

I'm 54 and my max HR is over 200. I can maintain 170's and 180's for extended periods of time.

I see people all the time in spinning classes who reduce their work loads drastically once they get a HR monitor. If you tell them that the monitors are useless or worse even unless you know your true max to then base your zones on, most people don't seem to care. I guess the thought of having to work harder to reach the zones is not appealing to them. Problem is they are often nowhere near the desired zones and thus not training the way they think they are.

I personally don't like wearing a monitor at all. Speed, cadence, trip distance are all good motivators for me on the bike, and in the gym at spinning classes I go full out most of the time anyways and don't worry about my zones in the least.

For a true recovery ride a monitor might be nice, because they are often hard to stay low enough to actually recover properly.

I just don't like being so aware of my HR. A personal thing.

It wasn't my choice!! I was doing sprints (running) in my Kinesiology lab.

I'm still trying to figure out my max HR. The highest I've seen so far has only been about 186, and that felt pretty tough. I can keep my HR in the 155-165 range though for a few hours. I'm in pretty decent shape with quite a few miles, so I'm not a noob by any means. Just odd that I can't hit 190+ considering I'm 24.

I'll have to try doing sprints to see if I can get higher than 186... running gets up HR up quicker. I'll give it a try tonight or this weekend.

Do you have any decent climbs in the area? You can probably get very near your max if you sprint blindly up the hill until you're about to die, and it wouldn't take very long either =).

Tried it, both on off road and on, and the climbs were moderately long, so not just a quick sprint over a roller hill. I can get to the top cross-eyed and feeling like I'm about to crack my head, blow a gasket, and spit a cylinder and some valves straight through the block and out the fender... and can't hit 190. Maybe I need to get a bottle of NOS. My road rides usually average ~18mph +/- 1mph over 45-55 miles on my hardtail with slicks, so I'm not being much of a slouch, either.

220-Age yields a result of 166 for me. I can hit that during TV commercials while on the trainer.

Sounds like what I feel like when I'm red-lining...maybe you just have a low mhr. You can probably do more work at a lower heart rate though, right? It all works out...
