What's Really Holding You Back? | The Secrets Of Heart Rate Variability With WHOOP

[@steven6358]

Not sure why all the hateful comments. This video was amazing. Very informative and great questions / answers asked. Watched it several times. The science behind recover is very interesting and is definitely more than just "get some rest". It's great to be able to quantify why I feel great from one day to the next when I haven't seemingly done anything different. Thanks guys!

[@doozlamuller7887]

Steven Palomino yeah, don’t understand so much negativity, wouldn’t mind giving it a go for 6 months, might help me stop drinking as much. And improve my biking performance.

[@danklegsjay]

Yes, please, more analyses like this! As someone who has just started following pro cycling as a spectator sport in the past couple years, content like this is super instructive to understand what's happened in the race (and what the consequences may be for future stages) with greater nuance.

[@gcn]

Thanks Jake, it's intricate and fascinating stuff eh?

[@danklegsjay]

@@gcn I actually meant to leave this comment on another video, I think-one of the longer stage analysis videos Si and Dan did toward the end of TdF-but I'd watched it on my Roku and then typed the comment on my phone after the fact, and I must've clicked the wrong video. Anyway, more in-depth race analysis was the ask! That said, HRV is pretty neat stuff too, and I'll keep an eye out for videos about it, too. I'm actually thinking of trying Whoop, but not just for the training benefits. When I started cycling, it wasn't something I did for positive mental health outcomes, but after having spent a couple years pushing myself to ride greater distances at faster speeds, I have definitely noticed improvements in my alertness, my ability sustain deep focus and attention, my capacity to manage stress and anxiety, and my general mood and disposition... and, wouldn't you know it, HRV is strongly correlated with all those things, too. Another KZbinr has a great video on the subject: kzbin.info/www/bejne/goDIanqEeql-kJo So maybe HRV training isn't just a fitness hack, but a life hack more generally.

So many people complaining in the comments about the price of the product and/or service. Please stop already. If you cannot afford it, don’t buy it. If you prefer a different product, just use that. Nobody is forcing you to make any purchases here. It’s like the people who cry that GCN doesn’t review low end bicycles. Guess what? Few people would watch it. The Mazda 2 is a great little economy runabout, but we all want to see Ferraris track tested not Mazda 2s. The same reason we want the scoop on Super Record EPS equipped Colnagos or E-Tap equipped S-Works Venges. Most of us will never get the opportunity to try these things for ourselves, and most of us cannot afford to buy them. So we enjoy learning about them through our beloved GCN presenters. Keep up the good work, GCN! #nocrybabies

Medlife Crisis would look at this and probably laugh his ass off, he has a "duck like a quack" series going on, maybe he'll spend a moment to debunk the whole HRV concept. Or maybe not, who knows, he seems like a busy individual. But it's interesting you've got one math buffin and one kinesiology guy, together they spin some crazy theories in the absence of any actual health care individuals. I really liked the lady's explanation about HRV reacting meaninglessly to everything in the world but less so at night when you're sleeping dreamlessly, yet the photo from the peloton shows some guy wearing his WHOOP while riding and presumably not sleeping dreamlessly. And expecting some worthwhile result? Or just psyching out the gullible. Who could know?!

Timely! I've been looking into this since seeing how some athletes (e.g. Kate Courtney and Phil Gaimon) use Whoop to train and recover. Mine was delivered yesterday. I really appreciate the deep dive and the clear explanations.

[@shawnbottom4769]

This needs to be expounded upon. They explain that reduced HRV is from stress and that stress can have many sources. But what do you do with that information? Not train at all that day? Train in a lower zone? I don't get to pick and choose when I have time to ride so I certainly wouldn't let an HR device keep me off the bike. In fact that's counter-intuitive since the bike IS my stress relief!

[@sudduthjonathan]

I've been tracking my HRV and resting HR via different apps since November and now Whoop. The way I feel during the day and during workouts is noticeably different when I am rested and without high levels of stress being placed on my system. But the balance between high recovery and making fitness gains is the key balancing point. The point here is that these devices mostly only measure these values. It's up to you to figure out what you can and shouldn't do to improve your recovery and strain. You need to experiment and track these things over time to really understand how it applies to you. For example, say you have a race on Saturday. Should you train hard Tuesday and Wednesday, take Thursday off, and go light on Friday? Or, do you need to back off more and take Friday completely off? You start to understand how training and the rest of your life adds to the overall picture.

[@indonesiaamerica7050]

HRV is an indicator. I don't think they actually explained what to do with this insight. Basically, you need to monitor this data (ideally, 24/7) and then pay attention to patterns. If you use Garmin (or similar) fitness monitors (I use a Fenix 5 and a Forerunner 935) it will throw out scores based on algorithms (relationships between the various data streams that are recorded) and basically point out when you're not sleeping well or resting enough. What you can do about it is notice when you're not getting enough rest/sleep but also think about nutrition habits and timing. For me, sometimes I notice problems when I forget to drink enough water in the hours after long sessions and if I drink something like a soda in the middle of the day without a meal. This shows up as "erratic" heart rate "beat to beat" or "HRV" but also elevated HR-BPM (beats per minute) compared to normal (for you) and then you have to figure out what is happening. For me it also matters if I add protein to my breakfast (I tend to eat only a little since I start hard sessions within an hour of waking up). Since all of your exercise is also recorded it will flag you as overtrained or whatever. If not, you have to figure out what you're doing differently that is not recorded directly by your hardware. Also, if you want to take a more detailed HRV test some of the better straps will do it (instead of filtering and averaging BPM it actually records the precise time of each beat) and create a FIT file for you to look at. The next step is getting an ECG from a cardiologist if you think you need it.

I surf directly to WHOOP website since I watched this video with the the sole intention of buying this device (honestly I don't usually use to buy things out of emotion, but I was going to), but as most of us immediately step back with the subscription monthly fee (It was as an orgasm, pretty high emotions and them pretty low, low emotions). I mean it would be good and useful to have that data in your wrisband, but I see a lot of people no buying that ridiculously membership and I see a lot of people who buys the membership canceling before the year. First I think it's killing the product before gets strong, second stop the company to start gaining momentum which is crucial and third it gives others the opportunity to copy them (even make better) and do right what WHOOP should be doing now. I made the math and If I used this band for 10 years it would be 3,000 Euros, what wristband does it cost that crazy amount of money . WHOOP the comments says everything...

[@usersense5738]

Heart rate variability can't be measured accurately over night like the Whoop strap does. It needs to be measured seated, every morning under the same conditions with an accurate monitor. The Morpheus M5 strap uses the only clinical validated monitor to measure HRV for consumer purposes. Also from a recovery standpoint, most wearables measuring HRV, show a sudden high increase in HRV as good, resulting in a better recovery score, which is not the case. When HRV suddenly rises, the parasympathetic branch (also known as the 'rest and digest' system) of the autonomic nervous system gets dominant meaning the body is trying to recover from any mental and/or physical stress. So adding too much training load may result in a low HRV score because the body wasn't fully recovered and shifts back to the sympathetic branch (the 'fight or flight' system) due to additional stressors. A higher training load would be appropriate again when the HRV score returns to basline (which is the average HRV score of a certain period).

[@bpfastfeet25]

Plenty of ideas that simply stem from fairly established science, BUT the key here is that WHOOP is making it accessible to the everyday person!!! Every sport scientist knows that the variance person-to-person is wildly more drastic than any average "rule of thumb" (i.e. quitting gluten because your favorite pro did it.) That's exactly why it's so important to be able to analyze yourself, rather than following trends blindly. Without a WHOOP strap, you'd have to hire a sport scientist or physical therapist to give you continuous private consultation... ($$$). NOTE: I don't have any relation to the company. Just a sports nerd and big fan of the awesome data! Big props to Emily! She has such a clear mastery of the info. Great to see a glimpse of the passion for sport clearly driving this whole company.

[@Tex735]

I'm a numbers nerd and have been doing EliteHRV for about the past year or so. It is hard to get a good HRV reading when you first wake up because you start thinking about stuff immediately, or at least I do, and that appears to skew the numbers a bit. This might be a better idea. We'll see.

Ha ha, we couldn't find a picture of Si suffering 😉

@@gcn sounds about rite 😂

So the basic is: monitoring the time of your hear rhythm and analysing that to understand when your at your peak, or well rested so you can train at your peak? The wider the variance in your heart rhythm the more rested you are? So the less my heart rhythm fluctuates the more tiered I am? Seems like a reverse in logic to me. Steady consistent is good usually. Erratic wide fluctuations bad usually. Did I understand her or not?

She's obviously a very smart Data Analyst type, but not a medical professional. She does a good job of explaining human science in layman's terms, which is probably exactly her level of expertise. This conversation should have been her methods of data analysis with a person with more of a human physiology background explaining the science behind the data. It was pretty heavy on the human biology science.

So... I work as cabin crew on airplanes, I'm always jet lagged wonder how that could help my training and the fact that half of the time I´m working at night time. Btw can you wear it somewhere else besides the rist, since I wouldn't be able to where it there for work . So many questions...

Bro, how can i calculate steepest of road by android applications?. (From which application.)

[@TStark-vj2wo]

What? You visited my home town and didn't say Hi? Well hope you had a good time here.

[@gcn]

Flying visit, sorry!

I've never heard of "HRV falling off a cliff syndrome." I'll try PubMed again...

[@frankcarlsen4921]

So that is exactly the same advice that has been given forever. Get a good nights sleep every night and remember that you will only improve during rest. I love when Simon say "if I had only had this kind of information when I was a pro (long ago)". What kind of information is that exactly? It seems like the information that can be gathered are at best vague and inclusive.

GCN has finally found someone with a more croaky voice than Si ;-)

[@jasonmolihan6930]

You found Sheldon Cooper's sister.

[@markrskinner]

"Valley girl, she's a valley girl" as Frank once said.

[@charlyvanbuuren739]

Oké right for sure for sure... 😁

[@jeremyallen5056]

I’m sure Simon was swaying with his eyes closed through most of that. Reminds me of Percy discovering “purest green” but without the humour

[@Offgrid531]

I've been using whoop for a couple of months now and it is quite good. I've also been recording my hrv using my chest strap HR monitor and phone for a few years. As many people have said whoop is expensive and that the reason I'm going back to using ithlete. For us cyclists strain is measured more accurately using watts anyway.

Wish I had this in Architecture school, after the 2nd night up I assume the app would just be screaming "GO TO SLEEP!"
