My Garmin is consistently annoying, in that it requires BOTH before it will give realistic training effect and load data. Still, I don't often bother to wear the chest strap, while I almost always have power data. It saves me from getting carried away when starting into climbs. HR responds too slowly, to serve the same purpose. I use HR monitoring about once a week when indoor training, to check my HR at a specific reference power level. That lets me know my current health state, and whether or not it would be a good day to attempt any new PB's.

@stuartdryer1352 Місяць тому
The weakness of a power meter is that it considers that the only physiologically meaningful stress is what you are putting into the pedals. This is a serious issue where I live, Houston Texas, where summer temperatures are typically around 35 C. Under those conditions, the heart needs to pump a significantly greater amount of blood into the skin in order to thermoregulate when you are exercising and consequently , the ratio of your heart rate to your power increases quite dramatically. That extra cardiac output is certainly part of the training stress that makes you stronger, but also from which you have to recover. Under those kinds of conditions , if you try to pace a ride based just on power, you could get yourself into serious trouble. And over time you need to account for it. However, fitness tracking software like Training Peaks doesn't fully account for it in calculating training stress or fitness.. Heart rate has the advantage in that it is really integrating the sum total of all of the physiological stresses at a point in time. Basically, your heart rate is higher because it needs to be. With that said, power meters are pretty useful, but both are better. Just dont buy avtwo side crank based PM if you use Shimano cranks.
@DWMtukwila Місяць тому
I think HR is number one but power meters allow for more bragging rights I think
@stuartdryer1352 Місяць тому
@DWMtukwila For sure, if it's an either/or situation, use HR. Both are better than just one, but in either case you need to enter the right parameters to get your zones right. Also, at extremes of heat or altitude, know that your HR/power ratio is going to increase at pretty much any perceived effort, and under those conditions HR is more "true".
@DWMtukwila Місяць тому
I think the zones are incredibly variable. My max heart rate at 67 is 175. According to the parameters I am often over my max hr. So the zones come are not accurate. I will change the age to match my HR. That will put the zones in the approximate range (I think it is always approximate)@@stuartdryer1352
@matthewnormand2041 Місяць тому
I notice when I visit home along the Gulf Coast in the summer from the West Coast and I go for a ride. My heart rate is considerably higher for a given effort than I'd normally see. It's clear the body is working hard to keep itself cool. Not acclimated to the heat and humidity.

I'm hoping for optical lactate meters. This will be the ideal tracking device for me. You would always get your zones right. I use HR. 1. Cheaper 2. I train for general fitness, not biking performace. I don't need to hit certain Watt numbers, but need to make sure I stay at the right level of excertion. Power does not align with your relativ daily capabilities as HR does - it's on the other hand better if you train for specific scenarios.
@DWMtukwila Місяць тому
Ah, but if your speed has gone up for the same heart rate and course/conditions, you can decide if you have improved biking performance especially if you can see the specific change like a better aero position. I train for fitness and riding better/faster and of course fun.
@veganpotterthevegan Місяць тому
We're probably not close to those actually being accurate. Even the optical heart rate sensors are pretty terrible for anything outside of sleep. I know mine is over 15bpm off at all times on the bike and upwards of 50bpm off during hard intervals, and it can be even worse in the cold
@hectorrusinqueolaya9286 22 дні тому
Lactate meters will definitely be a game changer for the average amataeur athletes. I think, level of exertion is more accurately estimated by power meters or the "talk test" than HR, at least if you are still far away from your HRmax. 1. HR response to effort changes is lagged. 2. HR drift (cardiovascular drift) during a training session is due to dehydration or/and the body response to an increased heat output, that not necessarily affect your "metabolic gear". If you are still calmly nose-breathing after a 50 min run, you are still in the same Zone 1 independent on whether your HR increased from 135 to 145 bpm.

A good heart rate unit only will cost about $40 if you buy a Chinese brand. The computer and the strap. I have been using heart rate monitors since they came out. As long as they use a chest strap they all seem equally accurate. These also come with apps so tracking is easy. I think you completely miss one point in HR training. It is excellent for improving efficiency. If my heart rate goes up then I am putting in more cardio output (effort) , If my speed improves and my heart rate stays the same, I am getting a better ratio speed to effort. It could be the way I breath, my saddle height or most anything. The heart rate and breathing do not immediately respond, as you mentioned, but even in shorter rides, flat or level, you can readily compare any changes you have made. Keeping at a specific chosen training heart rate is also desirable

The biggest thing missing in the mix is temperature. Temperature both core and just the normal temperature effects the power and the heart rate the most. Just knowing the room temp and basing it off your heart rate or power will give you the most accurate understanding of what you can push. Without temperature people are aways lost and always miss calculated there zones or power.

@paulgrimshaw8334 Місяць тому
I have been training regularly with a chest strap HR monitor for four years. A good one is very accurate and responsive. The tendency for heart rate to start lower per unit of force is normal. It’s also safer and better for you because it doesn’t snap load your cardiovascular system. But each device has its role. If you’re training your CV system, go with the HR monitor. If your focus is muscular, get the power meter.

I think this whole topic deserves a lot more attention. The biking scene is really changing fast. Just a year ago, power meters were not common as original equipment on road bikes. Go to Canyon's site, and about half the road bikes have power meters as standard equipment nowadays. Moreover, if you're a Zwift user (everyone should be a Zwift user in the winter-- it's really incredible) then you have to have a heart rate monitor to race. So that's standard now, too. As a result, power and pulse are becoming really standard metrics for training. There's lots more to say on this, incorporating it with training zones. And that brings up Strava, which shows your time in various training zones. Lots to discuss there, too.

It is the combination of HR and Power meter which gives the best information. I use golden Cheeta to plot HR versus power and the slope of the plot gives me a clear indication of my fitness. I don't really care about the actual power level I can generate but compare ride with ride as the season goes along. I can see that at the end of winter the slope of the curve is steep, meaning my heart has to work hard top generate the power and then towards end of summer, this drops markedly and I can generate the same power but at a much lower HR. By the way, I am 70 years of age and had a CABG (8 years ago) and the HR monitor is my primary safety device, set to give me an alarm if my HR goes above 155.

Regarding the differences in power - I think aslong as you train and race with the same measuring device that its neither here nor there but if you train with a one device on your training bike and another on your race day bike, that could be problimatic. Regarding the HR differences, thats massive. For me, the difference between 170-180bpm isnt too noticable but 180-190 is pain train zone.

@johnhickie1107 Місяць тому
Use of meters depends on what you want to get out of the information. Heart rate gives me an idea of how hard I'm working physiologically. With an L5 nerve root compression that starts to hurt at higher cadences, speeds or grinding on steep grades, I'm never going to get to my physiologically possible power output anymore, so a power meter for me is absolutely useless. For instance, climbing Mt. Ventoux this summer I could monitor my heart rate and cadence. The combination of cadence and heart rate gave me an idea of how hard I was working and whether I could push a little harder or pull back a bit before the nerve pain in my leg started acting up. Worked great! So, use the monitors that are right for you. For me, the heart rate monitor - even if it's a bit inaccurate as outlined by you guys - allowed me to temper my effort. I got to the top feeling fantastic by the way.
@bengt_axle Місяць тому
I use power indoors and HR outdoors, because that's what I've got. The advantage of HR on a climb is that it tells you how much cardiac reserve you've got left before blowing up. So if you know your max is 170, and you are at 165, you'd better back of unless the top is near. It also shows you the cardiac drift (and lag), which may be more important than keeping a constant power. This matters more than power to me, as I'm a recreational rider looking to just get to the top comfortably. All of my hard training is done indoors on the same smart bike that returns power and HR. I think a power meter could be helpful on a hilly course, but I consider them too expensive. If it were a $300 option, (dual sided) maybe I'd go for it.

The more advanced optical HRMs like on the high end Garmin watches track extremely well with the chest strap. My old watch used to under read the chest strap like Alex's (and would throw the odd glitch) but the Fenix reads almost identically +/- 2 bpm. I think the biggest issue with using heart rate alone is the lag , but the combined data allows analysis of relative general health and overtraining etc as well.

I ride to both and look at both, with different priorities. Going for a longer workout I will ride to HR but still look at power: Knowing your power numbers gives you a ballpark of the power output needed to reach a certain HR zone. But as HR drift (due to dehydration, fatigue or heat) might kick in, I will need to adjust power output as I might miss my training goals otherwise. Shorter (more intense) efforts are where power really shines as measurement: As HR lags behind, I would miss my training goals when training according to HR in these.

Good stuff. My approach is to use HR when training my heart, and PWR when training my muscles. That is, for long cardio rides my primary concern is heart rate, and I evaluate drift/decoupling after the fact to determine how to adjust the duration of my next cardio ride. For everything else I target power zones. I check drift on threshold workouts to determine how to adjust my intensity. In both cases, I want to see drift creeping in toward the end of the ride. This helps make my training blocks more "closed loop" so I can change training emphasis based on what my body is tellimg me rather than a calendar based on the average of a bunch of other people.

I eventually ended up visiting the ER one evening when an episode had been continuing for over an hour, and that's what led me to see an electrophysiologist. But the only time I've seen huge numbers like that from an HR monitor, was from an old chest strap that was due to be replaced. Seems I only get about 2 years service from them, before readings start to become erratic.

Why not both? I ride to HR for Z2 but for most other training, I ride to Power Zones since im training for my first metric century and i want to be able to maintain a certain power. Also just good to know your HR at all times when exercising.
@matthewnormand2041 Місяць тому
Seeing how this was filmed in Gerona, ¿Por qué no los dos? A watt is a watt no matter what but I still use heart rate mostly to indicate how my body is feeling and responding to my efforts and other factors (weather, fatigue, hydration, etc...) As for recording heart rate, chest strap seems to be for more responsive and consistent than my Whoop band or smart watch.

@julianallen515 Місяць тому
A very good reminder that repeatability is the most important factor if you have multiple power meters and HRMs. I dislike chest strap HRMs as they always slide down my lats so I favour wrist mounted HRMs which use Photoplethysmography . Another good point worth raising is that, without the commitment to learn how to train with these tools or employing a coach, they are just expensive toys.

The cheapest and most accurate HR available today is huawei watch fit 2, it only costs around 120-140 dollars. But now days high end smartwatch like apple watch uses ecg to record heartrate which is very and more accurate than using photoblablabla.

@TwiinStar1224 Місяць тому
This is my first year of training and I bought a HR monitor chest strap. Power meters are expensive and are a lot more of a fuss to setup. At the end of the day I'm training for a charity ride (hoping to do 75km in 2.5 hours) and do weekend group rides. Unless someone is a professional, all the power meter data is a bit useless. The people who truly need power meters tend to get them for free.

@MarkSmithSa Місяць тому
If you are 50+ then using the heart rate, measured with a chest strap, is critical to avoid atrial fibrillation. Yes there can be a lag, like in any control system, (as the brain needs to measure the change in demand of oxygen from the exchange in the arteries, veins and lungs) and then ramp up the rate of the heart, but I find that lag to be about 30 seconds at most when going from flat to a steep climb. By all means record power as a measure of improving strength but heart fitness is infinitely more important to your health and longevity of life.
@mstrasser Місяць тому
Use both, but Power is how i train. also, not surprisingly your crank powermeter is higher - it's a Shimano if i'm not mistaken which is HORRIBLY inaccurate. I also get the same HR variations between my whoop (on my wrist) and chest strap

The only thing constant about stock Shimano PM's is they have being constantly crap since they ditched Pioneer. Its embarrassing really I picked up one of those Magene PES PM Cranks for the Gravel bike and it matches almost W for W my Kickr, and My Assiomas and it cost £260, it's a very good/nice crankset too (unless you aren't into that "ROTOR" look). Even my old long suffering Powetap 2's complete with mild bearing play stay within a couple of W of the trainer. What is it with Shimano and cranks?
@wobyone Місяць тому
Surprised by the extent of the differences. If you haven't already, can you conduct the same test on an indoor trainer (after a decent warm up) and remove more of the variables.

@maytagman6591 Місяць тому
Ideally you should ride with both... and know how they correlate. Examples, if in a ride your heart rate isn't going up to where it normally would be for a given effort, it may be a sign you've been overtraining. Or if an hour into a ride in zone 2 your heart rate starts spiking you're probably dehydrated...
@peterharrington8709 Місяць тому
Without specifically saying so, I think you've demonstrated the superiority of the simple chest strap HRM. Seems to me Alex has gone up there 'pretty hard'... Zone 3 and that would, for him correlate with the 155 average heart rate? He produces some impressive power on that too. 142 BPM would have been Zone 2.... and it clearly wasn't that unless he stopped half way for a selfie 😁 Does it matter? Yes. If you want Zone 2 miles they need to be just that, but more importantly, at the top end you definitely don't want to be pushing way beyond your maximum heart rate and literally ending up flat out and needing CPR.
@user-cx2bk6pm2f Місяць тому
I think single-sided power meters can be quite good. My single-sided crank-arm 4iii matches reasonably well with my RallyXC dual-sided pedal meters.
@marianneoelund2940 Місяць тому
They're fine if your legs are well matched for power output. In my case, the left leg is normally 5-8% weaker, so I would have under-reported power if I used a single-sided meter. And right now, my body's in an abnormal state (still recovering fitness after a hip fracture) and I need to watch the L/R balance to see how the left side is recovering.
@user-ws2jw6wg7f Місяць тому
If you want to be really accurate then perhaps using lactate acid measurements is better but that is really involved to do it properly. For the vast majority of people does the variance really matter, especially if you are always using the same measure? It’s just a guide for most people 😊

Just be aware a Watt after 15min is not the same as a Watt after 3 hours of Zone 2 or at 15 Degrees vs 30 Degrees. Don't fall for perceived accuracy. Learn to combine power, heartrate and RPE into a meaningful picture of your load and your bodys response to that load.

@robinseibel7540 Місяць тому
Well, the likely reason that you saw that 5+% difference between the Wahoo power pedals and the Dura-Ace crank-based power meter is that the Dura-Ace power meter has horrible accuracy. @GPLama has detailed this extensively. @DCRainmaker called the same power meter "astonishingly inaccurate." This information is easily available and has been widely discussed. It seems like a pretty significant procedural error to do a comparison such as this with a crap power meter. After two tries so far, Shimano has yet to produce a precise and accurate power meter. Oh, dual-sided power pedals, Favero Assioma Duo--arguably one of the most accurate and precise power meter systems out there--can be had for as little as £575, far from £1000.
