Garmin vivomove Sport: A Scientist’s Review 🧪
Even look like a smartwatch im talking about the the garmin vivomove sport over the last weeks, ive really grown to like this 180 smartwatch, which seems to be punching above its weight in some areas, though, it also performs less well in other areas. This hybrid smartwatch looks much more like a traditional watch and might therefore be a good compromise for those people who do not like the look of a smartwatch but still want to track their health. The watch has a small, relatively low resolution, touchscreen hidden near the bottom of the watch, face to enable some smartwatch features in this video ill test. The sleep tracking heart rate, tracking auction saturation and step counting of the garmin vivomoo sport ill. Also briefly, compare the vivomove sport to the garmin venue, 2 plus, and the garmin fenix 7.. I wont do a gps accuracy check since the watch does not have built in gps. Instead, it uses the gps of your phone during outdoor exercises. Now, the first few days, it did take me some time to get used to the touch screen, especially since the watch does not have any physical buttons at all. After once, i got used to it. I have to say it worked quite well its also nice to see that the hands of the watch move to a quarter past nine. Once you start using the touchscreen making sure that the whole screen is visible, no matter what time it is one downside compared to some other garmin watches, is the battery life now its not bad, but at best is average coming in at about 5 days, according to Garmin lets move on to the test results for those of you that are new to the channel.
My name is rob and im a postdoctoral scientist specializing in biological data analysis as a side project. I like to test the performance of health trackers and in this video i want to start with the sleep tracking of the vivomove sport since im, uniquely positioned to test the sleep stage tracking, like most new garmin watches the vivomove. Sport has advanced sleep monitoring which tracks your sleep stages, oxygen, saturation of the blood and your breathing rate to check. If the heavy move sport can attack my sleep stages, ill, compare to an eeg device called the dream. 2 that can actually measure my brain waves and has been shown to be relatively reliable at sleep stage tracking. Here i show an overview of the sleep test results now. I should note that the room 2 is not the gold standard in sleep tracking. The gold standard is actually polysomnography a quick side. Note. A polysomnography device also makes for a great halloween costume, after forgetting an overall impression of how well the viva move. Sport performs the dream. 2 should be good enough now, on top. Here are the sleep stages, as recorded by the eeg device on the left. The sleep stage, as recorded by the fifa, move sport, our both the eeg device and have even move sport to bed for eight nights, and i will see how close the predictions off of even move sport are to those of the eeg device. Now each column here sums to 100, meaning that we can see what percentage of each of the sleep stages.
According to the room, 2 was predicted as each sleep stage by the vivomoo sport. If they perfectly agree, all values on the diagonal should be 100. First of all, we see that almost 90 of what was deep sleep according to the eeg device was also deep sleep according to the viva move sport. If they did disagree, this was mostly with light sleep, but also sometimes with rem sleep. We can see that even better by looking at the individual knights like this example knight right here. On top, we have the sleep stage according to the dream: 2 eeg headband, with the clock time on the horizontal axis and the sleep stages on the vertical axis. On the bottom, we have a similar plot, but now for the vivomove sport, ive highlighted all the eeg recorded deep sleep in purple here and, as you can see, theres a pretty good agreement between the eeg device and the viva move sport, and for this second example, Knight we see something similar where they get a nice match between both of the devices light. Sleep detection also agreed pretty well with the eeg device at about 70 percent. If the fifa movie sport did disagree, this was mostly with deep sleep and ram sleep ram. Sleep protection was also surprisingly good, agreeing with the eeg device about 70 percent of the time now. This is where most devices struggle, which also makes it impossible for most devices to pick up on the sleep cycles.
If the vivimu sport did predict something different than the eeg device, this was mostly light. Sleep thats also confirmed by looking at the individual knights in ram. Here i marked the ram sleep as recorded by the eeg device and, as you can see, theres generally a pretty good agreement between both of the devices you go through roughly four to six sleep cycles, each night, each one, starting with light sleep and deep sleep marker In blue and each one ending in rem, sleep markedly in red, as you can see, i had four sleep cycles this night and because the ram sleep also appears to be recorded quite well by the vivomoo sport. We can also see the cycles based on just the data from that watch, and we see something similar for this second night right here, with mostly good ram sleep tracking, and that means that the sleep cycles are also visible. Based on just the data from the vivomoo sport, awake detection shows the biggest disagreement between the eeg device and the vivomoo sport, with only 50 percent of the awake moments. According to the eeg device, also classified as awake by the vivomoo sport. In most cases, the disagreement was at light, sleep and rem sleep now, looking at the individual knights, this disagreement mostly seems to be there because the longer awake moments do agree between both devices, but the shorter ones do not agree between both of the devices normally. I also record myself with an infrared camera, while sleeping, and that allows me to check if the longer clear awake moments also show up on camera.
However, i just got a new internet provider and i still have to reinstall the camera on the new network. Those of you that watch the videos from the last two weeks might remember. I wore either the garmin venue, 2 plus or the garmin fenix 7 on the other arm, whilst testing the vivomove sport. This showed that these devices did not agree well with the eeg device indicating that theyre less good at sleep tracking heres one night of sleep tracking, with both the phoenix 7 and the vivo sport on top again is the eeg headband in the middle of phoenix 7 And on the bottom of evermore sport in purple, here i marked a deep sleep according to the eeg device and, as you can see, the viva moose sport agrees much better with it than the phoenix 7. for rem sleep. We see mostly the same thing for this night. The phoenix 7 has a very unlikely ram sleep pattern, not indicating it detected any sort of sleep cycles. However, if you move sport on the bottom did show a nice periodic signal. It agrees much better with the eeg device indicating the different sleep cycles only for awake detection here in green does the phoenix 7 appears to show a better agreement with the eeg device. Maybe the vivomoo sport is just less sensitive to movements and changes in heart rate. Overall, though, the vismos sports teams have quite good sleep stage tracking. I cannot explain why two garmin watches show such a difference in their sleep stage tracking.
I actually switched if you move sport from my left arm to my right arm and the agreement with the eeg did not change so far. I always assume that all new garmin watches run the same algorithm. One hypothesis is that the sleep staging might still improve on those other watches, as is collecting more of my data. If so, the account i connected to the viva move, sport might have had better data from previous watches. I tested that being said: garmin also released the beta firmware update for the venue 2 line of watches that supposedly also improves sleep tracking. This graph shows an overview of the agreement of different watches with the eeg device along the horizontal axis. We have the average agreement over the four individual sleep stages and on the vertical axis we have the agreement of the worst sleep stage, the better the agreement, the more to the top right. The watch is, and, as you can see, the best agreeing watches include different fitbits. In this case the fitbit sense inspired 2 in charge 5, the ubstrap 3.0 4.0 and within sleep analyzer. As you can see, the phoenix 7 venue 2 and venue 2 plus do not show a high level of agreement. However, the viva move sport is close to the best agreeing devices if it were not for what seems to be less sensitive with wake detection, it would be amongst the devices with the highest agreement. Next lets move on to the heart rate tracking.
However, as you might have noticed, this review was out a bit later than that of most reviewers. That is because garmin did not lend me to watch the review before it came out, and i have to buy all the watches myself. If you want to help the channel get noticed by garmin a sub to the channel and pressing like on this, video would really go a long way and will also help me get these reviews out faster. But, of course, its totally up to you now last week we saw that the heart rate tracking of the phoenix 7 was decent, though not great. What about the viva move? Sport, which actually has an older generation of sensor, lets look at the results during spinning cycling and weight lifting in the next set of tests ill. Compare the heart rate measurements of the vivomoo sport against the polar h10 ecg chest strap, which can generally record my heart rate very accurately, well start by looking at the easiest type of exercise for a watch to track cycling indoors. Now this involves very little movement and will therefore produce less noise. Here we see an overview of that accuracy. Each dot is a single heart rate measurement, with along the horizontal axis, the value according to the polar h10 ecg chest strap and on the vertical axis, the value according to the vivomove sport. Overall, there is a pretty good agreement between the ecg chest strap and the vivomoo sport, as most points are along the blue line.
However, there are still quite a few points away from the blue line, both above it and below it, indicating it detected both too high and too low heart rate. Looking at this first spinning session, we can already see what it likely is now in this training. I did an interval training and each time my heart rate changes drastically. So when i take a break, it goes down and up again the vivomove sport has a slight delay in picking that up. Additionally, here in the beginning, it struggled a lot more in this second spinning session. We see something similar. It really struggled here during the first break, and it also had delays in picking up the changes in my heart rate, especially here and here, and we see something similar in this last example. I want to show it really struggles most in the beginning and after that it has these delays, but theyre not as bad as in the first part of the training. All in all, this is not terrible. However, i would say that the phoenix 7 from last week did perform better but ill show that comparison in a bit lets first take a look at how the viva move sport performed while cycling outside generally. This is more difficult for watches since theres much more movement than bumpiness and as you can see, there indeed appears to be more deviation compared to what we saw for indoor cycling, and we can see why that is by looking at the individual rides here.
We indeed see that if you move, sport in red deviates quite a bit from the ecg chest, strap in blue, and we see the same thing for this second ride right here now. This third ride looks a bit better, though, in the beginning, it still struggled quite a bit. This is basically what we see overall for all the results. Some rides show quite an okay agreement like this one right here, but at least, as many rides show quite significant issues like in this one right here and thats. Also what we see for this example right right here where for part of the ride it totally missed. My higher heart rate next lets take a look at the most difficult type of exercise weight. Lifting an example of that is displayed here where each peak in blue green is a set that i did as you can see. Only on a few occasions, kind of even more sport keep up with the increases in my heart rate, this is because the tension on my arm and wrist makes it harder for the watch to actually track my heart rate, and we see the same thing for this. Second example session right here, where it basically misses all the peaks. In my heart rate – and this is a very consistent pattern – we basically see for all of the workouts, so the vision moves sport performed decently during spinning, but based on my data, i would not trust it so much for cycling outside of weight.
Lifting if we compare the results for the phoenix 7 from last week on the right right here to the v move sport on the left for indoor cycling, we see that the phoenix 7 appears to do ever so slightly better, though the difference is likely not significant. However, looking at cycling outside, we see a larger difference with a better agreement of the ecg chest, strap with the phoenix 7 than with vivomove sport. In addition to tracking my heart rate, the sensors of the v move. Sport can also measure my oxygen saturation over the last weeks. I measure my oxygen saturation at ground level in the morning and in the evening using the vivomove sport. At the same time, i also record my oxygen saturation using a dedicated fingerprint exhibitor at ground level. My oxygen saturation should be within my normal range, which is generally between 97 and 100 percent and should not drop below roughly 95 percent. So if you move, sport should not detect any low values. During this test on, the left are 20 measurements taken with the viva move sport and on the right 20 matching measurements taken with the fingerprint recommender. As you can see, the measurements of the vivomove sport are mostly in the same range as the fingerprint exhibitor. However, it does detect slightly lower spo2 values. Still all measurements are near normal range, since there are no values below 95 percent. Overall. This is not bad, however, as always, i would recommend that when you get a low measurement with any device, you reposition the watch on your wrist and take a few more measurements.
That way, you can ensure that the low measurement was not a fluke additionally id like to test the watch in a low auction environment to see if it can detect a low oxygen saturation. Next i went out, and i took exactly 4 000 steps, while wearing the garment viva move sport to check if the step counting is any good. Now, since i do not like counting 4000 steps in my head, i manually counted my steps using this tally counter. I actually counted my steps in 4 segments of 1000 steps, switching the telecounter between my left and right hand, which is what the left and right labels refer to here and i would have even moved sport on my left arm now. These are the actual steps counted for each of the four segments and, as you can see, the numbers are pretty close to the actual 1000 steps. The vivo sport does tend to overcount my steps. However, we saw something similar before for the garmin venue sq, and we also see the same for the phoenix 7 and the garmin venue 2 plus i wore at the same time as the vivomoo sport. Both of these also tend to overcount my number of steps, so, even though it does tend to somewhat overcount my steps, the step counting of the vivomove sport seems to be pretty decent. However, one thing a lot of watches do wrong is that they count steps when theyre not supposed to count steps, for instance, while cycling or even working at your desk.
So this is something i still want to test in the future. Now its really interesting to see that the sleep tracking appears to be quite good on this relatively cheap garmin watch, whereas other garden models show sleep stage patterns that are not like what my normal sleep cycles are like. I hope that it is either a matter of software updates need to be performed on these other models or that in time the algorithm will improve, because it has more data to work with. Based on the results i showed in this video, i would recommend if youve removed sport for sleep tracking, if youre interested in tracking your sleep stages and your sleep cycles. As with many watches, i would suggest pairing an ecg chest, strap to it. If youre interested in tracking your heart rate during sports ive a given that the v move, sport was quite okay during static indoor exercises, i would expect to be good enough for tracking your heart rate when resting the spo2 tracking and step counting appear to be reasonable. Based on the limited tests, i did, but additional testing is needed for more definitive conclusions on their overall accuracy if youre interested in the tests, i did on other newly released garmin watches check out those videos right here. If you want great heart rate tracking from your wrist check out the videos on the apple watch series 7 right here. Finally, all my tests have their limitations and im making a video explaining those once that one is out that will be linked right here now.
I hope this video provided you with some value.
