Did a 35 mile ride today. I felt great afterward. Too much headwind slowed me down a little though. Garmin showed my average HR was 84% of max, and much of the ride I was between 87 and 91% reported. In bpm, that's 156 average. I'm 41, and calculated max is 186. On an interval the other day, I hit 182(98% reported).
Wouldn't those percentages beat me up? I'm not a racer, nor am I 22 years old.

Aerobic training via max Heart Rate and "Grey Zone"



Hi All, I am a rookie on this forum so please forgive me if I am doing this wrong, but I have a question regarding heart rates and training as well and would appreciate anyone who could direct me....................
I am fairly new to all of this and am looking for some advice with respect to proper aerobic base training. I am 45yoa, 5' 11" tall, 205 lbs and have been riding recreationally for about 5 years. I have decided to start club racing and am undergoing winter indoor training now primarily with the spinervals series. I plan to make TT the discipline of favor as at my weight, I will be no Andy Schlek in the hills. I just did a lactate threshold test (OUCH!) and estimated my LT to be at a heart rate of 167. From various charts and graphs my max HR would be 185; although I have never seen anything on my HR monitor above 174. It may be that my heart rate is generally lower by genetic design and I can accept this, but it does create confusion in figuring out my training zones. Troy Jacobsen preaches to keep your HR 10+ beats below the LT for aerobic base building or about 80% of your max HR. It is also important to avoid the 80-85% grey zone where you are essentially in no man's land (to hard for aerobic and too easy for LT improvement) 80% of my max HR would be no higher than 148. 10-15 beats below my LT is 152-157, which would put me right in the grey zone that I would like to avoid. Can anyone tell me where I should be?
I do not want to waste time on the trainer and be in the grey zone, but need to be assured that I am indeed working hard enough to get the benefits of the aerobic base that I am looking for. I am not afraid to work harder, but want the work that I put in to be of benefit.
I would appreciate any feedback or advice that anyone can offer!
Thanks!

Still, those percentages seem high, don't you think?
Who knows? Provided you are fit and healthy, then just go and do a hard ride, finish with a decent hillclimb and sprint the last 200 metres as if your life depended on it and see what your HR gets up to after that. You'll have some idea then.

If your actual HRmax is higher or lower, then the ranges could be high, low or typical.

I have two friends of same age as me, we have a HRmax that differs by over 20 beats per minute between us.

Maybe, maybe not. You need to do an actual max HR test to determine what your true max is. There are a number of ways to test it. In the early 80's, the formula was 220 minus age, which is outdated, and can be very inaccurate. My actual measured HR was 8 beats higher than the formula, so its way off.

Once you test and measure your true max with several repeated tests, only then can you know what true max is.

Also, as Alex will agree, HRM is not the best tool to base bike training on. For us runners, its adequate, but power meters on bikes are more the norm versus a HRM. Consider a power meter to help you train on the bike. I will consider a meter if I decide to get back into performance riding.

I'm 64 and did the climbing leg of LOTOJA a couple of weeks ago. Average HR was 156 and max 168 for over 2.5 hours and 47 miles. The 156 HR is 88% of my estimated max of 175. Your figures don't seem high for a youngster of 40!. As you get in better shape you can stay in your upper zones longer without excessive lactic acid buildup.

Do a a Lacate Threshhold test, then you can get close to your MHR by adding 5 beats.

Warm up for 15-20 min. Then to a 2-3 mile TT. then get the Avg MHR during that TT. That's your LT, then add 5 beats for a MHR.

I am 42 and my LT is 187, but my MHR is 191BMP by testing and having my HR recorded every second.

I'm 39 and according to the 220 minus age BS, I should have a max HR of 181. I know my max HR is right around 200 (I saw 204 doing sprints a few years ago). My LT is around 173 and at 178 I feel like I'm working real hard... mid to high 180's on short steep climbs.

I do have a question regarding HR. Is it bad for me to average mid to high 160's for 2+ hrs? It seems that my HR wants to be in the 160's unless I take it really easy (it will go down in the 140's when coasting downhill).

I'm not using an age based formula. I'm using what Garmin has determined my max is. I've done a full-out sprint and got the numbers I've posted. It just seems that if I'm riding with the percentages it's showing, I should be worn out after a ride.
I ride 2 to 3 times a week, and on many rides my average speeds are upper 16's to lower 17's. I'd say I'm in average shape for a cyclist.

Without using high tech testing, what do most people do to figure out max HR? I ask this because on a bike my max HR going up steep hills seems to be in the low 190's, however if I do uphill sprints (running) I can see 202-203. Just wondering what I should base my % on.

Peanya, I can average 166-168 HR for 3+ hours with no problem feeling like I'm going at a comfortable pace. This is less than 10 bpm from my LT. I don' t have anything scientific to back it up, but I assume that if you stay below your threshold you can maintain for a long time. I'm not sure if I could ride with an average in the 140's unless I was going one way down hill with the wind.

Without using high tech testing, what do most people do to figure out max HR?.
If you routinely do very hard all out type efforts from week to week, a good estimate is to take the highest recorded HR value from the last few months. Keep in mind if you actually did know your current true max HR, it would still vary from week to week based on how recovered you are and your riding volume. Also always double check HR monitor data that may contain a new max HR reading, occasionally the monitors will report bogus data. An indicator that the data is inaccurate is when the second by second HR values jump around by more than 2-3 bpm at a time.

Feeling adventurous? Now that you have your estimated max HR, get on the trainer one day and make a deal with yourself that you will not get off until you've matched that max HR estimate again. Then, when you finally get there, dig as deep as you can and just keep going... preferably out of the saddle to maximize your exhaustion. A good way to get to your "max HR" again is not to just immediately go as hard as you can - if you do it this way, your muscles will just give out and you'll likely fail pretty miserably at maxing out your HR. Instead, start out at FTP pace. After 5-10 minutes you should be 90%+ "max HR", at which point begin gradually upping the pace over the next few minutes. I would recommend staying in the saddle until you reach 98-100% "max HR", then stand up and go for it and don't sit down til you see 101% or wimp out :D

Is there really a reason to know Max HR?

I don't think it's important. If you are a casual cyclist, makes no difference at all. If you are training to race or for even centuries, then your zones are all based on threshold, not max hr.

If you are using HR to determine zones then you must also focus on RPE at the same time as HR will drift and vary from day to day and week to week.

wow, some of you guys have some serious max HRs! Is that a function of how long you have been riding?

I've been riding 5 months (age 39) and my max has been 174 in a crit. I feel like I'm working really hard when it is consistently over 160, and usually in tempo rides it's 150s. I'm wondering if either 1) I have never reached max HR or 2) I need to keep riding and eventually my max will increase?

EDIT... my resting HR is 50-55 (usually closer to 55)
 
#18 ·
Like new2rd said the number itself is not an indicator of fitness. Also, and my experience may be different from others, when I first started riding my approx max HR was in the low 180s. Over the course of about a year it gradually increased and peaked at 202. Then, it began slowly decreasing and for the last few months has been at about 194. So basically, expect it to change and don't expect to understand why!
 
#17 ·
Max HR really isn't an indication of how fit you are... some top athletes can have Max HR's in the 200's or 170's. Resting HR is a good indication of fitness. I only use the Max HR as a guide. From what I've heard the closer you can get your LT to your Max HR, the better off you will be.

Back when I was in peak running shape (age 20), my HR range was 38-205. I proceeded to not do any serious exercise for several years beyond bike-commuting and occasional casual sports. My resting HR is much higher now at 56, haven't checked my peak.
 
#21 ·
I'm pretty sure that my HR calculation is off, as when riding yesterday, the readout said 103% during a sprint. When I got home, however, the max recorded was 184bpm. So I'm figuring my max is probably 186~188ish.

I'm 49; my RHR is 59. According to my cardiologist, my MHR is 174. I ride between 50 - 100 miles a week (contingent upon South Florida weather, a/k/a T-storms), and I'm constantly in the 160+ HR range. Last Saturday I rode 61 miles and my HR peaked at 183. In one occasion, I pushed it up to 191. Still here and have not had symptoms of fainting, or being out of breath. Sure I'm breathing hard, but never out of breath.

The only area of concern for me, is that my heart rate has taken as much as three hours to get below 100 after a long ride at an elevated HR. My last stress test (10/14/11) showed no abnormalities at all, and I intentionally brought myself up to my doctor's "MHR," but only for about 15 seconds. Of course, my HR got below 85 in less than 5 minutes after the test. So now my cardiologist wants me to wear a Holter monitor for 24 hrs on a day I do a ride.

Just today I read about EPOC (excess post-exercise oxygen consumption), which happens to be in congruence with what the stress test's tech mentioned.

Does anyone have some insight on this?

Thanks!!!

Hm, your actual max is much higher than the calculated max. You're able to ride long distances at 90% of your calculated max, so I suspect your actual max is the figure I would use.

My actual max is about 175, and if I rode at 160bpm consistently, I would be severely fatigued. (I'm age 39 with RHR of 56). Strange how one's MHR is different than that predicted by the age formula.

As for the long return below 100bpm, I think that's simply a consequence of your body recovering from a hard workout.

As an aside, I really think most physicians (I'm one also) are not too familiar with how the body responds to vigorous aerobic/anaerobic exercise. Even cardiologists are really more focused on caring for "sick" hearts than healthy ones, unless they specialize in exercise physiology
 
#25 ·
I appreciate your feedback. Your take on your profession is intriguing. It would seem reasonable to infer that someone who specializes in healing the sick should also know how to keep people from getting sick. But, in retrospect, it doesn't seem that far fetched.

I suppose you're right and I should look for a doctor who specializes in sports medicine
 
#26 ·
whoa, let me back up. I'm sorry, I never meant to imply you should find a different doctor. By all means, keep the one you have. He/she is looking out for your health and is most likely doing a great job of it.
I simply meant to say that sometimes us physicians don't get the proper training in regards to healthy hearts and what to look for in a highly conditioned athlete heart. A properly trained coach might be a better pick to answer the questions you have, :thumbsup:
 
#27 ·
No, I think I'm the one who should apologize, because I knew you didn't mean that such is what I should do. I just didn't phrase it properly. What I meant to say is that I should also seek the opinion of a physician who specializes in sports medicine. Although a coach is not a bad idea as a source for an answer to my question, I think I'll have more luck with my medical carrier paying for the consultation if I seek the former.

Based on everything I've read, I'd forget about your max. You can't control it, and it doesn't matter. As the other folks have said, figure out your LT and train off of that. One protocol is a 30 Min TT, and take the HR avg for the last 20 minutes. That's LT. Use that number as your anchor for zones, not your maximum. Your LTHR will rise somewhat with training from what I understand, but it then levels off. For me, 158 is SST, 161 is LT, and 170 and up means explosion imminent. YMMV. I'm 42.

Max means nothing, and might not even be your true maximum. Your "max" cycling probably won't be the same as your max running, for example, and the formulas that are used might assume running. (running tends to be higher).
 
#31 ·
I looked at this website: Joe Friel - Determining your LTHR
to get an insight on LTHR. Did a ride yesterday morning, but after re-reading what Joe says, I may have not done things correctly. The way I interpret what he writes, there are two contingencies he doesn't mention, but that presumably he assumes; a warm up period and appropriate time for pre-exercise nutrition to metabolize.

I ride every other day in the morning. If I was to ride after work, I'd be up past midnight. So, I get up at 4:30 to ride in the morning and I'm usually out of the house by 4:45; ride for an hour and get back home in time to get the family going. I do have a bite to eat before I do my ride, but the interval of time is definitely not enough for it to metabolize. So, I'll do it again this weekend and see what it tells me. Yesterday's ride said my average HR for the 20 mins was 163 and a peak of 175. I simply don't believe yesterday morning's "all out" was a true "all out."

The measurement of heart rate is used by medical professionals to assist in the diagnosis and tracking of medical conditions. It is also used by individuals, such as athletes, who are interested in monitoring their heart rate to gain maximum efficiency from their training.
Wow; there's something I didn't know :rolleyes:

Hoping the best for you RickJP, I hope it all gets sorted out.
Having gone through similar issues with my heart and heart rate, etc. I can relate.
I had a 4x bypass in March after the angiogram I had led to 100% heart block,
I had a 4x bypass (I was on an external pace maker for 2 days) then had open heart surgery.
After the surgery, I went into Atrial Fibrillation. Went on Amiodarone and the Afib passed while I was still in the hospital.

Started cycling 3 weeks after the surgery, and after I got stronger, when I would hit around 130 BPM I would go into rhythm related heart block, basically I would go from 130 to 75, or every other beat. Then back to a normal rhythm in about a minute or so.
First my Cardiologist took me off Coreg and it got better, I could hit say 140 before the rhythm related heart block kicked in.
Then he took me off Amiodarone and eventfully the rhythm related heart block went away.
That lasted for 4 months or so.
Then I started having PVC’ -s Premature Ventricular contractions, so the Cardiologist put me back on Coreg 3.125 twice a day.
That did not do much so he increased the Coreg to 6.25 twice a day, but warned that this could bring back the rhythm related heart block.
Yep, it did, on a 50 miler last Saturday, after the last climb of the day, at around 30 miles, my BPM went from 150 to 77.
Had to have the group wait until the episode passed, about 1 minute.
Finished the ride, called the doc on Tuedsday, and he backed off the Coreg to 3.125 2x a day,
I rode last night and hit 151 BPM, and so it does seem better.
To me the most important piece of equipment I own is my HRM, I monitor my BPM very closely and I know not to push it.

I believe you are doing all the right things.

Good luck!

Thanks CABGPatchKid. Looks like you're doing the right things as well. Stay strong! :thumbsup:

Thank-you Alex! I don't get too hung up on the whole HR thing, but found it a little confusing that where I was supposed to be differed depending on what ideal I used. For me to maintain 2-2.5 hrs at 85% on the trainer would not be that big a deal at my current level. I traditionally ride rolling hills to steeper climbs (7.5-9.5%) where I live and my HR usually will hang out in the 160-165 range. The LT test I just did averaged 167 for the final 20 min and 165 for the full 30 min. The max I saw during this test was 170which would probably be in the 90% area where I feel I should be for a TT. Although I do not have a great power meter I do have on that is supposed to be calibrated for the trainer I have and noted that when I was working at that 90% level, I could maintain around 345 watts. I tend to watch the relative speed on the computer and lie to be between 35-40 km/h when I train for distance. If the Grey Zone is a myth, then I will allow myself to get my HR a little higher on my aerobic days while still trying to keep it aerobic. I understand that the Max HR test is falling out of favor as it is being percieved as a bit risky especially if there is a unknown underlying cardiac condition. I was considering dong one in the next couple of weeks, but am unsure that it would be of any benefit of knowledge to my training given the percieved effort I endured during the LT test. Do you have any thoughts on this?
 
#43 ·
It's very hard to train for any length of time at anything but aerobic levels, you have no choice really. Once you begin to use anaerobic work capacity, the time you can continue to ride at that level for is significantly limited (reduces to minutes). IOW you'll be forced to slow down anyway to a pace that is wholly aerobic "pay as you go" level.

Just start where you are, and adjust from there. You'll find out soon enough if you can or can't go harder. Just give yourself a bit of a mix of efforts.

If you are overweight, have a history of cardiac issues, are/were a smoker or are in any way concerned about doing hard efforts you should consult your doctor/physician before embarking on any exercise regime.
