In other words, its important to monitor blood oxygen saturation at night to detect potential health issues before they lead to more severe problems. For example, a study from 2010 showed that epileptic seizures induce a surge in EDA. Are people really that unaware and so determined to believe what a device is telling them? They are so unreliable that a real athlete cannot base her training on these and I have used different top models from Polar and Garmin. He recommended to reach out to support via the app (which sends a diagnostics file). If youd like to give WHOOP a try, you can use the link below to get one free month added to whichever subscription you choose. The WHOOP app offers a treasure trove of information, and you might find it intimidating at first. So I never experienced any issues. If your strap is bad, youll get it replaced. One of the most common questions people ask us is why they should use WHOOP over other devices. This is not a forum to debate vaccines, take it elsewhere. The Oura Ring is a fascinating device that packs numerous wearable technologies into a tiny form factor. Check out https://michaelkummer.com/health/whoop-accuracy/ for more information on that. You can learn more about HRV and how to improve it in this blog post and YouTube video. I dont know exactly if the root cause of this problem is that the motion sensor confuses the force of the impact (i.e., the tapping) with a heart beat, or if its because the optical heart rate sensor shifts around and thus doesnt get a good signal. I still like it, the band is superior to most other trackers and having sensitive skin there is no other tracker I can wear so well. You can access your athlete profile by clicking on your profile image in the upper left corner of the home screen. In theory, the additional LEDs and photodiodes should improve WHOOPs HR measurements, especially under less-than-ideal conditions. If you suspect your heart rate readings are off during workouts, consider covering the sensor with a sleeve to keep it more securely in place.To learn more about WHOOPs accuracy as a fitness, recovery and sleep tracker, check out this article. From my experience Whoop does a terrible job estimating the caloric expenditure at low HR. Despite being the best performing published algorithm of its kind, it has two primary issues first it was fit only to exercise conducted at an intensity of 57%, 77% and 90% of Max HR and therefore untested above and below these intensities, and second it was found to explain only 73.4% of the variance in true energy expenditure. So stay tuned for that. Ill cover the WHOOP Journal in more detail below, but in a nutshell, understand that it enables you to make better lifestyle choices to improve your sleep and recovery. While you may be getting good sleep, what do your other metrics look like compared to your baseline? On the flip side, you shouldnt be in the red for two weeks in a row. But I dont have any hands-on experience because I dont have tattoos :), Es wre gut, wenn die App auch auf Deutsch wre. @valerie_bedrock. I am looking for a fitness monitor that is accurate enough for my profile (not a competitor/athlete) the will provide a more fully featured range of health metrics and the Whoop sees to fit the bill. As a result, I build very little cardiovascular strain. While Im excited about all the new features introduced in WHOOP 4.0, there are still a few things missing that could improve the overall platform. For example: if you walked casually throughout the day, your Strain score would most likely remain low; because despite being active, your heart rate (including cardiovascular load) did not elevate. However, my wife feels best with 8 to 9 hours of sleep much more than Sleep Coach recommends. That fixed the issue for me! I have tested it against other competitive products which has led me to this conclusion. The most commonly used heart-rate-based formula for estimating caloric consumption during activity, or so called active calories, was developed in South Africa in 2005. Your WHOOP cycle begins when you fall asleep, then resets the next time you fall asleep (some other wearables operate on a fixed 24 hour cycle, which isnt an accurate portrayal of your bodys routine). Maybe well get there at some point, but we arent there yet as of this writing. Instead, its more useful to understand the trend of your HRV compared to previous periods.However, since we all like to share and compare, over the past month my HRV has been bouncing between 26 and 74. Additionally, you can also check your respiration rate (how many breaths you take per minute). If youve endured a tough weightlifting session and are still sore, your bodys working overtime to repair, recover, and get stronger. Those 2000 calories you believe you consumed could easily have been 2400, an error bar approximately the size of a McDonalds Double Cheeseburger. Whats important to understand is that being in the red isnt necessarily a bad thing much like being in the green all the time isnt necessarily a good thing. Emily Capodilupo is VP of Data Science and Research at WHOOP. What Id like WHOOP to add is the ability to set your own sleep goal in hours and minutes. 6-month membership: $30 per month ($180 in total). I recommend studying undergraduate level exercise physiology to grasp a bit how complicated and fine machines we are. It offers no useful analysis and reporting around exercise performance and recovery. The first icon gets you back to the home screen from anywhere in the app. I havent tried the Oura yet, but its on my todo list :) Is higherstrainalways better for any fitness goal? From missing nights data to not recognizing activities, and an inability to correctly record sleep (even after manually updating it to correlate to my other devices). Thats the same battery life as the WHOOP 3.0 and it lines up with my hands-on experience. Its either maxed out, or average/resting. This is why WHOOP developed theStrain Coach. However, our internal physiology might be telling a different story. Said differently, Ive had days where I crushed a workout despite having a low recovery score, and days with a high recovery where I didnt feel like my best. At WHOOP, we seek to keep our members informed about the latest technology in the app and how they can apply their data to real-life training and performance goals. With your experience would that be an issue? That seems absolutely ludicrous to me. @gavinkerr95. 34% - 66%. So yeah, I think the biceps band would be an excellent choice for your needs. But there is plenty of independent, peer-reviewed evidence to suggest EMFs from cellular devices, smart devices, household electricity, and appliances (dirty electricity or electrical noise) have biological effects. Speaking of sleep labs have you ever tried that? Strain Scale In other words, Ive gotten a lot of value out of my membership. I was torn between Oura and Whoop. An hour of walking at a moderate pace for me should be around 300-350 cals but my HR rarely goes above 50%, so Whoop basically groups it in 0-49% HR and gives me ridiculously low cals like 70. I consider that an opinion thats not based on actual, scientific evidence. As a result, we track a few different metrics: WHOOP shows you the amount of time in bed, efficiency, disturbances, respiratory rate, and sleep staging by tapping on Hours of Sleep in your app. I may dive into that next. Proper positioning of the strap is crucial for the accuracy of the signal the sensors receive. In a nutshell, the WHOOP strap offers excellent accuracy in the following areas: Heart rate variability (HRV) Recovery Respiratory rate Resting heart rate Sleep quality and stages of sleep However, you might experience mixed results in the areas of heart rate tracking during certain types of exercises. If an app exceeds the allotted memory, iOS kills it. WHOOP VP of Data Science Emily Capodilupo has written about theconcerns associated with elevated respiratory rateamidst the coronavirus pandemic. Idk man i burn like 4000 a day. With the release of iOS 13 and the launch of the iPhone 11 and iPhone 11 Pro, Apple doubled down on extending the battery life of its devices. Hi Michael, First, thanks for the accurate review and comparisons, truly appreciated! One of the things I immediately noticed when I put the strap on for the first time was that WHOOP doesnt have a display or buttons. your responses in the user input form provided after every workout will not impact your Strain. Thanks you for your post if was very informative. Many WHOOP members have wondered how their data will reflect a strenuous strength session, so heres the breakdown: In order to read true muscle breakdown following a workout, youd need additional tools such as an EMG or blood test. The most accurate way to calculate calories burnt during exercise is through a process called indirect calorimetry which measures gas exchange (oxygen and carbon dioxide). Keeping tabs on your blood oxygen saturation (SpO2) is a new feature that is made possible by the new blood oximeter built into WHOOP 4.0. Much like EDA, your skin temperature changes in certain conditions, such as during strenuous exercise, when you have a fever, or during certain parts of the menstrual cycle. Strain does not operate on a linear scale, which means the higher your Strain goes, the harder you should push your body. Thanks for the extremely thorough review! It also lets you know how much sleep youll need tonight, based on your level of activity during the day and any sleep debt you might have accrued. Im just wondering how the Whoop algorithms would handle that and if it would just negate the whole effectiveness of their platform. The strap should be tight enough so that its difficult to stick your pinky between the strap and your wrist. Have you considered that your strap might be defective? Last Updated: Jan 11, 2023. 33% or below. Besides that WHOOP has the data to proof its accuracy (which very much depends on how tight the strap is), Ive compared HR readings of a chest strap, my Apple Watch and the WHOOP during CrossFit workouts. So whats left to complain about? Over time, Ive come to realize that there needs to be a balance between strain and recovery. Strain tracking is more reliable for cardio workouts (than HIIT or Olympic lifting). In comparison, the WHOOP 3.0 (and its battery pack) had three LEDs that provided a more fine-grained indication (eight charge levels) of how much battery you had left. As an enthusiastic CrossFit athlete and healthy living advocate, Im always on the lookout for ways to hack my performance and improve my sleep quality and post-workout recovery. And the battery pack is finally water-resistant, so you wont damage it when you (accidentally) take it into the shower with you. This is an unethical business practice and it speaks volumes about the character of the Whoop company. How the hell did I see people burning 3-4K calories a day on some of the random groups Ive joined? This conversation started several months ago during which I was quite patient however when the refund was requested the correspondence ceased. However, WHOOP also uses the accelerometer to assist with heart rate monitoring (the sensor is sensitive enough to pick up individual heart beats) and to keep tabs on your respiration rate while sleeping. Thought I was going nuts. Provides insight into your daily strain and recovery rate, as well as detailed sleep performance data. While some people have complained about lower-than-expected strain scores, others have experienced the opposite. Im currently performing some more tests and then write up my findings in a blog post. In other words, I was much less exhausted building a chicken coop than I usually am after completing much shorter (but more intense) CrossFit workouts that lead to a much lower strain score (usually between 8 and 15). This is not a forum to debate vaccines, take it elsewhere. Its also a membership that connects you to a community of like-minded health enthusiasts. Based on my experience with WHOOP tracking my heart rate during CrossFit workouts, and previous data captured by chest straps, Id say that WHOOP 4.0 is much better at reflecting my actual heart rate during those challenging workouts. For example, Im convinced that my heart rate during the workout in question was much higher than 154 (what WHOOP 3.0 reported) just based on how exhausting it was and how heavy I had to breathe. See here for mt July data: https://www.dropbox.com/s/lco7vwve8l3o7q0/Screen%20Shot%202020-08-17%20at%2008.33.48.jpg?dl=0. They need to fix their lack of integration swiftly if I am to continue, certainly. My dominant hand is my left-hand. While WHOOP showed a heart rate of over 110 beats per minute, my chest strap accurately reflected my heart rate, which hovered around 70 beats per minute. Thats one of the reasons why companies like Biostrap stick with silicone bands, even though it renders their bands less comfortable and more difficult to adjust. Either way, I hope youll get your defective unit replaced asap and wont end up paying for the time you couldnt use it. Thats because these two restorative stages of sleep look relatively similar from the outside. 2) it references a new metric HRV but does not give any insight into how to address it and what is good or bad. That said, Im currently testing the Biostrap Evo, which came out after I published my initial WHOOP vs. Biostrap review. Make sure you are allowing time for the body to heal and repair before stressing it all over again, or your body will not be able to recover as quickly the next time. For my running I use a Garmin Forerunner 235 which has the built in HR monitor. Additionally, WHOOP has made it super easy to swap bands, thanks to the new Fast Link system. Another study I found on a similar subject confirms the accuracy of wrist-worn devices when there is no movement involved check it out: https://www.researchgate.net/publication/323417048_Can_Wearable_Devices_Accurately_Measure_Heart_Rate_Variability_A_Systematic_Review, The review is appreciated. Im wondering if you know how Whoop performs in hot gyms. While Im sure using a hammer and drill and lugging lumber around for several hours increased my heart rate, I didnt have to go all out. Why. As a result, I firmly believe that WHOOP 4.0 more accurately captured my HR data, calorie burn and cardiovascular strain. I have read many reviews over the last week on a spectrum of fitness monitors and yours stands out as convincing me that I should give the whoop a trial run. Will it track my distance and any other info since it doesnt have gps? The activity tracker on the Whoop gives me roughly the same amount as well. You have to see your recovery score in the context of what youre trying to achieve. Combine it with a good 3rd party sleep app like AutoSleep that detects your recovery using HRV, and you get legitimately great feedback on recovery and how much you can push yourself every day. Then it was finally time for a CrossFit workout. Thats one of the reasons why Biostrap decided to lump both deep and REM sleep into a single metric instead of trying to differentiate between the two. My point here is that while new tech is awesome and it can help you many ways, you still have to use your judgement and not become slave because oour technology still fails us quite often. I think thats a terrible business practice: refuse to provide the service already paid for.
