I have a few years of experience with the Polar H10 & both Polar & Garmin chest straps. I only use the H10 for cycling, both indoor & out. For the past several months I have included the Apple watch SE in this testing. The H10 & the SE match up quite reliably for average HR. If there is a difference, it's no more than 1or 2 bpm. They both line up quite well with the chest straps. I've always used the chest straps for weight lifting but now use the SE almost exclusively. Again, the variation between the two wasn't enough to warrant the continued use of the chest strap. I'm 188 cm & approx. 75kg. So obviously I'm a bit on the thin side and also light skinned. Your mileage may vary.
During the long runs and hot days I often get rush from the chest strap. I’m happy I was able to join the testing phase and have to say this HRM works well. The comfort is great, even after 14h of activity I didn’t feel it at all. And I was amazed how good the optical sensor can work if you place it on the upper arm. We were able to compare data from watch, chest strap and HR31 and even when watch OHR failed to show correct data, HR31 was identical with chest strap.
I exclusively don’t ever subscribe to youtube channels as I search for what i want to see and dont like recommended stuff. You’re so good at what you do i had to subscribe! Thanks a bunch. Hope this comment helps algorithm for you
0:00: 📊 This is a review of the Chorus heart rate monitor, comparing its performance to a chest strap. 2:47: 🚴♂ The chorus hardware monitor performs well in tracking heart rate during outdoor cycling. 4:23: :chart_with_upwards_trend: The chorus hardware monitor generally agrees well with the polar h10 ECG Jazz strap in measuring heart rate, with a correlation of 0.95. 6:32: 😕 The performance of the course hardware monitor is compared to other devices for different exercises. 8:49: 📊 The performance of the chorus heart rate monitor during weightlifting and spinning sessions was analyzed. 11:04: ⭐ The Chorus HRM performs well for cycling outdoors, but struggles during weightlifting. 13:21: 📉 The Chorus HRM may not accurately track heart rate for weightlifters and could be affected by different skin tones or tattoos. Recap by Tammy AI
Dear Rob, thank you for the useful info. Because you are using R programming (ggplot) for data analysis, I'd suggest adding to correlation plots a colour gradient linked to a time var (at least start, middle, and end). This would increase legibility and better understand the differences between sensors.
@@TheQuantifiedScientist Would you be interested in trying the pokemon go plus+ for sleep tracking pokemon has a wide reach and could get a lot of data for sleep tracking would be amazing if the data was accurate
I have really been enjoying your videos. I've been checking them out as I prepare to make some purchases. I notice that you regularly warn people that different variables including skin color could effect results. Could you do a video showing the difference in effective sleep and heart rate tracking for dark skinned people as compared to lighter skinned people? Thanks for the detail you provide.
Great video Rob just wondering if you've looked at the Coros Pace 2? I've got both it and a Garmin Epix 2 gen 2 watch. With the Garmin I've found that using a chest strap is must, especially during intervals or when it's cold. It will either drop out entirely or shoot up and this can affect the training and recovery scores. The Coros pace 2 however I've found to be flawless, for me it tracks almost perfectly with my Polar H10.
Been testing this for a bit now, and comparing to my H10 and this thing is right there. Past optical bands for me always seemed to be slightly delayed, but this has been great!
Best reviews on the tube! I'm wanting a slim affordable (cheaper) watch that does it all. So far I'm struggling, but it'll be on the strength of one of your reviews when I finally do find one 👍
Since you've already done this COROS and also the Polar Verity Sense, could you eventually do the Scosche Rhythm24? It's half the cost of the Polar Verity Sense, and its heart tracking seems to be nearly on-par with the Polar H10 chest strap. It's an optical sensor like the COROS and Polar VS, but somehow there appears to be zero lag in HR detection like you see with other optical HR sensors. The results are instant like with a chest strap.
You should do a review on the Frontier X2 heart monitor as its considered one of the best on the market. Would love to see it withstand some of your thorough testing! ❤
Please compare all the available smartbands. I don't really want to buy a smartwatch but I want something to count my calories and track my heartrate when running and weightlifting.
Mine is more accurate than my HR strap lol. When my HR strap gets too sweaty during a 2 hour run, it has major problems getting an accurate reading. My arm does not get all salty and drenched in sweat as much, so its perfect!
I just hope one day Apple Watch can broadcast its heart rate so I can use it with my Garmin edge, such an accurate hr device😢 I can only opt in for a Garmin watch, which isn’t really good seeing your testing with cycling outdoor, and my experiences as well, huge delay when my heart rate goes up and down.
Just found your channel and been loving your content! Just gotta ask: why are you wearing a Huel shirt? I just ordered my first order of ready-made drinks and got a shirt from them so I thought it was funny seeing it in your videos lol
you only tested indoors, the problem is the OHR gets very noisy with its reading while outside, on sweaty arms in hot & humid environment. I should wait for more test scenarios to decide whether to trust your data.
@@rainerrain9689 I own the ringconn and it doesn't need a subscription... At least for now. It's the main reason I backed it when it was on kickstarter, I was annoyed at oura charging a high monthly price when the ring upfront isn't cheap.
I normally wear a chest strap but when I train for the Murph challenge I wear a weighted vest and it makes a chest strap painful, I just ordered one of these, watches are a pain for cross training and weight training
Hi! Not silly 🙃. It’s about the technology used to measure heart rate. Watches use PPG, which is based on measuring the amount of light reflected back from the skin, and this is generally quite noisy. ECG uses the electric signals of the heart directly to get your heart rate. It’s the same technology type the doctor would use to study your heart beats and rhythms .
The strap comfort is a joke. I bought this and requested a return a few minutes after getting it from Amazon. The sensor may or may not be good. That is entirely irrelevant if it hurts to wear and I will never wear it. My biceps are small compared to body builders and weightlifting buffs. It will not open up large enough to fit comfortably. It is painful to wear. Your arms look slightly bigger than mine so I don't know how it is not digging in or pinching your arm. They label the strap as size medium when in reality it's the only size available.
I wonder if the typical late increase in heart rate could be related to how heart rate is measured. Since the heart rate is in beats per minute, I suppose it is computed doing something like (b/n)*60, where b is the number of beats over n seconds. What is the typical n? Having it too low would mean missing a beat varies the value a lot, bit having it too high makes it slower to keep up with sudden changes. It would be interesting if it was possible to get the "raw" data of when the beats were detected, and compare differente ways to compute the heart rate.
I wonder if doing a simple r2 isn't enough for correlation when most of the outliers end up isolated around patterns of good overlap. Is there any way of showing the chronological distribution of the outliers (half beat red line ones and/ or over estimations)
Probabily the distribution of the difference em measurements, with skewness, IQR and median would show how different and the direction of difference as well!
@LuizOliveira-er6ly I should have been clearer, I don't mean the distribution of the error or difference. In contrast to other types of variables, error in heart rate estimation has time domain components (number of heart rates not detected accurately in succession). We need something like a sparsity analysis but that can quantify outliers instead of fully missing data.
Yeah, definitely something I've thought about. I mostly did not do it because I want to keep it somewhat understandable for people 🙂. But, I;ve been thinking about extra metrics to include. Thanks for the suggestions!
One suggestion is to use the Bland-Altman graphic between chest strap and Coros HR monitor. I was very impressed when I was testing in real time, viewing 3 readings (watch, chest and HR31) very accurate. When I experienced out data was with the H10, likely, due to a movement on the chest. But Coros have now lots of data to improve firmwares 😉
I wonder what is the use of a HR strap, if someone is using a strap which can be anoying a chest strap will be better anyway. The optical HR is cool on the wrist because it comes with the watch, using a stra just for optical HR feels pointless.
How do you plan to show that any device can beat H10 if by definition H10 is 100% accurate in your tests? Having at least one more device would add confidence to the picture. I understand that it is used to be the industry standard but for me H10 frequently gives abnormal values when running. Do not have any problems though when cycling indoor or outdoor.
thank you for your review! question, is there any heart rate monitor that can be use with multiple user? I want to use only one heart rate monitor to my patients. thanks
Thank you for the very informative videos. One question though: I'm trying to find an armstrap heart rate monitor that sends it's signal also at 5.3 Khz. Sofar I didn't succeed. Do you know of any?
I already have a Garmin Forerunner 245 M. Wondering if I should get this or upgrade my watch to the Coros Pace 3 for more accurate heart rate readings while running? Which one would you recommend?
How do you get data (CSV) off of devices like the H10 to a windows PC (excel) without security/privacy issues associated with a cloud based account system? I just want want to see my accurate HR data after a training session, without being tracked. If i want to view it in real time, i will use a watch of a biking computer.
Have you tried the Polar H10 with exercises like bench press. I find that my Garmin HRM-Pro plus works poorly at this and other movements, where a gap can be created between the puck and my chest. It also misses beats when I bend over with my upper body and create a similar gap.
Hi, I read somewhere that Polar H10 can also do sleep tracking. I was wondering how is the sleep tracking of Polar H10? Didn't find any video on that. Any insights would be appreciated.
You can easily record RR data from the H10 with the Sensor Logger app and analyse it with Kubios HRV. Using spectral and detrended fluctuation analysis the sleep phases can be differentiated (LF/HF and Hurst-like exponents).

Yes, I have. It does mean one is somewhat suboptimally positioned, and I need to make sure they don't slide over eachother. They generally did very well, though I'd like to redo the testing
How does it compare to Polar Verity Sense? Also, it would be interesting to test it in different parts of the arm, I personally have the Verity Sense from Polar and it works great on the inside of my bicep, close to my armpit, where there's never much tension, not even while lifting.
Ich frage mich, ob eine Smartwatch getragen am Oberarm ähnliche Resultate erzeugen würde? Hast du Erfahrungen damit, ob eine Uhr die Herzfrequenz besser misst, wenn sie an Stellen mit großen Venen getragen wird? Oder spielt das keine große Rolle?
