    Whoop Launches New VO2 Max Tracking for Wearable Devices

    Key Takeaways

    1. Whoop has launched a VO2 Max tracking feature for its fitness devices, measuring oxygen usage during exercise to reflect heart and lung fitness.
    2. The VO2 Max algorithm uses thousands of data points, including breathing rate and heart rate zones, achieving accuracy within 8% of gold standard tests.
    3. Users can easily track their weekly VO2 Max score and monitor changes over one- and six-month periods through the Whoop app.
    4. To improve VO2 Max, Whoop recommends regular cardio workouts, a healthy diet, adequate sleep, and stress management.
    5. The VO2 Max feature is available for Whoop 4.0 users, priced at $239 on Amazon.

    Whoop has introduced a fresh VO2 Max tracking function for its fitness devices. VO2 Max gauges the highest level of oxygen you utilize during exercise, reflecting your heart and lung fitness. The firm explains it as “the ultimate metric for long-term health and performance”.

    Advanced Algorithm Insights

    The Whoop VO2 Max algorithm reportedly harnesses thousands of data points, including factors like breathing rate, recovery, time spent in heart rate training zones, and GPS information gathered during runs. This blend of health stats and activity data, along with demographic information, enables a weekly update of your VO2 Max. Whoop claims that the mean absolute percentage error of its VO2 Max measurement is below 8% when evaluated against gold standard tests.

    Easy Tracking Features

    You can feature your weekly VO2 Max score on your home screen in the Whoop app by navigating to My Dashboard > Customize. Moreover, users have the ability to monitor how this metric evolves over one-month and six-month intervals. Additionally, if you have a VO2 Max result from a laboratory test, you can manually input this on the Trends screen. It’s important to keep in mind that the VO2 Max estimate is only processed if you’ve had 14 sleeps within the last 21 days. Furthermore, accuracy improves when users log a GPS-tracked run lasting over 15 minutes and input their weight.

    Recommendations for Improvement

    Whoop recommends that users strive for a VO2 Max range of 35 to 40 ml/kg/min, highlighting that it generally decreases with age, which can lower your overall fitness level. To boost your VO2 Max, the company suggests consistent cardio workouts, a healthy diet, sufficient sleep, and management of stress. This new Whoop VO2 Max feature is currently accessible for users of devices like the Whoop 4.0 (priced at $239 on Amazon).

  • Whoop Update Boosts Sleep Staging Accuracy by 7%

    Whoop Update Boosts Sleep Staging Accuracy by 7%

    Key Takeaways

    1. Whoop’s updated Sleep Staging Algorithm enhances sleep stage detection accuracy by 7% and improves sleep/wake detection precision by 3%.
    2. Users may see changes in their sleep statistics, particularly in awake time and restorative sleep, but other metrics like Recovery and HRV remain unaffected.
    3. The update is based on two years of research from Central Queensland University and the University of Arizona, with high accuracy rates in heart rate and HRV measurements.
    4. The new algorithm was implemented on February 24th, and data recorded before that date will not change.
    5. Users of Whoop devices, such as the Whoop 4.0, will receive notifications in the app about the updates.

    Whoop has rolled out an update for its Sleep Staging Algorithm in its health and fitness trackers. The company asserts these modifications enhance the accuracy of sleep tracking, providing “clearer insights” into your rest and recovery.

    Enhanced Sleep Stage Identification

    Whoop states it has improved the way it detects the four sleep stages: wake, light sleep, REM, and deep sleep. The company claims this update has increased accuracy by 7% due to the integration of more data points. Additionally, there’s been a 3% boost in sleep and wake detection precision. This enhancement should result in fewer errors in identifying wake times, which can happen when you shift positions during sleep.

    User Feedback on Sleep Metrics

    According to Whoop, users might notice variations in their sleep statistics, especially regarding their awake time and restorative sleep data. Some users have shared on Reddit that they’re experiencing a noticeable decrease in their total wake times. However, Whoop assures that other metrics like Recovery, Strain, and HRV will not be affected by this update.

    Research Behind the Update

    The new algorithm started to take effect on February 24th, and any sleep data recorded prior to this date will remain unchanged. This release is based on two years of research conducted at Central Queensland University and the University of Arizona. The polysomnography (PSG) data revealed that Whoop’s heart rate measurements boast an accuracy of 99.7%, while HRV measurements are 99% accurate. Moreover, the brand’s devices have been shown to surpass competitors in calculating total sleep time.

    The improved Sleep Staging Algorithm will automatically update for users of devices like the Whoop 4.0 (currently priced at $239 on Amazon). Users can expect a notification in the Whoop app detailing the changes.
