    Resting heart rate is only part of the metric for fitness. So when there is an inaccuracy for a single data point for an overall picture it should be scaled to its value to the picture of fitness. Simply put, if resting heart rate is 50% of ones fitness and maximum heart rate is the other 50%, then a 5% spread in readings for one of those values becomes less significant to the whole picture. Since we know that fitness is multi faceted, more than one data point, more than Resting heat rate and maximum heart rate, then the discrepancy in sensor values is less critical. Still, this is a good observation, some people are looking for 1% improvement and this certainly illustrates that could be the case.

    I have an active lifestyle; I walk 3-4 km a day and try to eat healthy. My Apple Watch gave me Low HR notification while sleeping on 2 occasions which led me to goto ER and get ECG, Echocardiogram, and Holter Monitor done. They all turned out to be normal but it increased my anxiety so much that now I have to take anxiety medication and I am really wary of my heart. Apple Watch is a curse for me. I have stopped wearing it.

    I'm glad for this video because I'm not super fit and my Garmin says something about 46 bpm and I was starting to think I have a heart problem. when I sit still it is more reasonable about 55.

    An interesting discussion. It wouldn’t be the first time that technology forces the well known medical gold standard to be reevaluated. One thing I would note, not mentioned in the discussion was the impact of “variable” HRV (heart rate variability) which could easily corrupt getting an accurate resting HR. Different manufacturers may well have chosen different algorithms to manage readings. While we all need to be aware of the limitations of these devices, I push back on them as being “fake”

    I see the RHR value from my watch as a not totally accurate benchmark. I can see from one day to the next what is going on, even if I don't take the exact number as gospel. For instance it suggests early to mid 50s but the two times I got covid that daily average crept into the early 60s. Took a few weeks and ramped up then back down. Both times the same.

    Garmin is best as they don't charge you a monthly subscription to keep capturing and accessing all your own data. So no reason for them to 'flatter' you by trying to give a lower number. Yes, they may give a total based on night rate, but you can simply look at your own resting heart rate WHILE RESTING rather than relying on the device to give you a total figure.

    My polar gritx pro shows low 40:s sometimes under 40. ive done ekg at hospital and that is also low in par with the watch and have been asked from the medical staff if my pulse always is so low. So it seems that my polar watch is accurate. I workout nearly daily.

    Vital signs during sleep are misleading because medicine does not have much of a history of reconciling the numbers - heart rate, oxygen saturation, blood pressure, . . ., which can all be low enough to cause emergency medical providers to begin reaching for their drugs and devices to make the person's vital signs look more like the text book vital signs. Experienced providers will assess the person (patient) to see how the lower then considered "acceptable" vital signs are tolerated. As mentioned in this video, the text book resting heart rate range for "normal" is 60-100. That will probably change, because a range of 50-90 is more appropriate. The number is supposed to indicate when the heart rate has deviated from the norm enough to be considered an indicator of a possible problem. If your heart rate at rest is in the 90s, but is not normally in the 90s, that is not a good sign and MAY indicate stress, such as an infection or some other medical condition that should be treated. The medical definition of "normal" is often just statistically where 68.8% (2 standard deviations from the mean) of people are. Much more important is what is normal for the individual being measured. Someone with a "normal for them" resting heart rate of 48 is outside of both normal ranges for the average person. A change from that person's normal range is more important than the mean average number of 48. The range (2 standard deviations for that person over many days or longer) may be 42-52. The personal range is what matters in seeing whether something has changed with the individual, but a lower heart rate MAY also indicate a problem with the heart's conduction system and may indicate the need for treatment. We can exercise to the point where our heart is not responding appropriately to the feedback mechanisms that have evolved in our bodies, because our ancestors did not exercise as much as some people do today. .

    that looks like a Fitbit Charge. I used to own one of those. It was notoriously bad for tracking my heart rate when I was exercising hard and my wrists were sweaty. It would do pretty much what yours did at the end of your run. I now own a Fitbit Sense 2 and I don't have that problem anymore. I find that it is much better.

    I think this can be summed up as a more liberal/optimistic vs more conservative/pessimistic view of things for which we currently have weak/low quality preliminary evidence. Frankly, I have to side with Peter because as a biologist who has a fair bit of experience reading clinical trials, a heavy majority of interventions that seem promising (whether in epidemiological human studies or in animal/in vitro models) just don't end up panning out in higher quality RCTs.

    I think this comment misses the main point of the video here! (Which is perhaps my fault for not explaining it well.) The thing I take issue with is that Peter says we’d need a magic pill that cures ageing in the next decade for him to live much longer, which is absolutely not true-a series of treatments over the next 40 years could make a pretty big difference to people his age. I agree that lots of things won’t pan out-which is why I campaign for more funding for longevity science so we can try lots of them!

    Another thing is that the software doesn't really know how to measure that you are sleeping. I remember Garmin basically asked me WHEN I usually slept so I guess they might use that data, but that does not account for weekends when I'm sleeping longer or if I take two hour nap for some reason. I'm using Sleep as Android so it knows when I'm trying to sleep and it actually cones up with a slightly lower number as it takes a while to fall asleep, I might take a bathroom visit, as well I might be awake before I get up. When resting on a sofa watching TV I might get as low pulse as within the range during the night so it would be very difficult for Garmin to get this right so why not just give a damn and use the whole thing. Also it is cool to know the lowest heartrate I have and Garmin doesn't tell me this :-(

    I have a Fit Bit Charge and also use a Garmin. The former I wear all day and the latter mostly when I am exercising. There can be a wide variation between the two particularly with heart rate during exercise. Each has its pros and cons and the Fit Bit in particular has a few quicks. Neither is completely accurate so you have to use them as a guide monitoring your performance over a period. Also as long as they are consistently wrong in the same way over a period comparisons are useful. These devices certainly spur me on and encourage me to exercise more than I otherwise would.

    My age is 79 How come that whenever I think of going to the GP my blood pressure shoots up? and after the gym and I walk home my blood pressure decreases enormously? I have between 130 and 133 systolic; I have got it down to below 120 on occasions. while I have between 76 , (an outlier), and 85 diiastolic. I do the gym about two to three times a week. I need a day in between to recover. I hate the idea of taking drugs forever. I walk rather than run on the tread mill at between 5.5 and 5.7km/hr and do about 2.3 km in about 21/22 minutes. At about 1km my heart rate is about 110 to 115 ; my resting HRV varies between 69 and 85. At the end of 2.3 km "walk", my heart rate is between 133 and 125 depending on how stressed I am although I have got it down to 117 which I ignore as false. I sometimes row. Other exercises include abduction and adduction, torso exercises, deltoid and pectoral , deltoid exercises etc, I don't do weight lifting. For good measure I have enlarged prostate. I eat more fish than meat but TRY to avoid sardine and tuna to reduce the incidence of uric acid increse. I eat apples/pears/banana. for my breakfast I have muesli with 49% nuts, bran flakes and say pomegranite or strawberries Should I get worried? I hate going to the doctors' surgery. That has nothing to do with the doctors themselves, just me.
