Well, as you seem to realize, the 220-age is only a very crude approximation and it is easy to be 20-30 beats off of that estimate.

The way I have done it is warm up and then gradually increase the intensity until my heart rate maxes out. It me to have a competitor to increase my motivation.

Your maximum heart rate should be relatively constant over time (that is fitness does not have a big effect, or it never did for me) but it will not be the same for different kinds of exercise. I hear that people who run and cycle can hit higher numbers running.

Another thing is that you will find that how you feel at certain heart rates makes a difference and I use these sensations as training guides. For example, I am working fairly hard at 165 but I have no discomfort and I can sustain this pace for over an hour (never tried to go longer, always seemed to be enough). It is sort of like a "fast cruise". Above 170, things start to hurt. Maybe that is my anaerobic threshold and it works out at about 85% of my max.

The way I hit my max is on a fast group ride with a sprint finish. When I feel like I can't increase the pace anymore I sprint. For the last 4-5 years the max number is see is 197-201. I was tested and had a max of 197 so at least for me I believe this method works for me. Testing does have other benefits but if you just want your max HR that's a lot of money to spend.

I believed mine was high 180's for years. A few years later I rode the track and regulary saw mid 190's before my vision blurred and I was unable to read my HRM .. You *might* find that your Anerobic Threshold is a more useful number. It's easier to determine but it does fluctuate with your fitness. I believe the Friel book has a formula to estimate AT based on Average HR during a short <10 mile time trial.

The phenomenon is called "anticipatory heart rate". It's experienced a lot at racing events- you get to the start and your heart rate is THIS MUCH HIGHER than normal. Then your heart rate is overly elevated during the race. You always have to take this into account. One of Sally Edwards' books explains this a little more- can't remember which one, but I'd guess it was her book called ""The Heart Rate Monitor".

For those of you that say you had your max hr tested, who did your test? Where did you get it tested? From the way some folks were talking, I would think whoever tested them were not professionals. When I had my test done at the beginning of the summer, the guys came and slapped one of those oxygen tubes on my mouth and took a pin and put it over my nose so I could only breathe out of my mouth. Then they put a heart rate monitor on me and also had me on an ergometer. My friend had his done and paid the extra to have his ear pricked every minute so they could more accurately determine the concentrate of lactate in his blood. When I had my test, it took about an hour, then they took an additional 30 minutes to go through the results with me. They had me hooked to a computer the entire time. Then when they thought I was near max, they had me do an all out effort, and when they asked if that was as hard as I could go, I said yes, and they me push a little harder- they didn't let up until my eyes were bulging and I was gasping for like another minute. It was painful. So if you didn't go through that, I would say you weren't professionally tested. At the very least, professionals should know better than to test you and not push you to your highest limits. There's no reason for a discrepency of what people are describing here. The dudes that tested me came in from Toronto and were in town for a week at a fitness convention doing tests, so I paid to have mine.

I really do think that it would be more efficient to test anaerobic threshold, which changes with fitness, and that would be something worth checking into- since as anaerobic threshold increases, you will be able to sustain higher heart rates for longer periods, which is good for when you want to do your races.

Seconded. Max HR is a theoretic max anyway, you should never actually reach it.

Most universities will need participants in certain studies or labs for their students which involves this testing. Put your hand up to be in the study and they will normally do any additional testing that you want at the same time. Build up a relationship with the lab, they will call you if you they need you for a study and you can get your testing done for free.

how much did all of this cost you? i'm very interested in having it done by a professional.

the max HR "formula" is just an estimate...
but it's a good enough estimate for most of the training programs that use it to set zones. or just adjust the value -- if your supposed max is 185 and your HR monitor regularly shows 195, then use 200 or something as your max. ---> note the MAX is that - the HIGHEST value so you should rarely see it. mine is around 193/194 and i only saw a value over 190 once this year (primarily b/c when i am pushing that hard i am sprinting in a race finish or hillsprint and i don't LOOK at the HR monitor and my downloadable log only samples once every 10 seconds or so...)

(my opinion - other _may_ vary) good training programs should emphasize the Lactacte Threshold more than the max.

this you _can_ also estimate, but here a test is not a bad idea (i had one spring 2002 and it cost me \$60 discounted from \$80 by my club). this is the test where you ride on an egometer and they prick your ear for a blood sample every couple of minutes.

from reading and my personal observation i had estimated my LT at 165 and the test resulted in 164 (early season) and later in the season it climbed (my estimate was 169)

search the forum - i and others have posted quite detailed descriptions of how to estimate the Lactate Threshold.

Then it's much easier to go by anaerobic threshold- perceived exertion is something everyone can do and using it helps to determine what heart rate you start to feel out of breath at. From there, you can train around that number and as the fitness level builds, you will find it much easier to hold your cadence at that heart rate, where before, when you did your initial test, you were not. I've typed up the 2X20 anaerobic threshold test, but never a test on lactate threshold. That's a test that definitely needs to be done in a lab setting. Koffee
