Low VO2 Max on Apple Watch: Causes and Solutions

Your VO2 max reading on your Apple Watch may be low because it is an estimated measurement based on your recent workouts and activity levels. The Apple Watch estimates VO2 max based on the intensity of your outdoor walks and runs, so if you haven’t engaged in these types of activities or have not been doing them at a high enough intensity, then your estimated VO2 max may be lower than expected. Additionally, factors such as age, gender, fitness level, and genetics can also influence your VO2 max score.

Understanding VO2 Max on Apple Devices

A good VO2 max score on an Apple Watch can vary depending on age and gender, but typically a score of 40 or higher is considered a high level of cardiorespiratory fitness. For men aged 18-25, a score of 40-46 is generally considered to be excellent, while for women in the same age range, a score of 37-46 is considered excellent. However, it’s important to remember that everyone’s fitness level is different and thee are many factors that can affect your VO2 max score.

Measuring VO2 Max with Apple Watch

Apple Watch uses a combination of your heart rate and the intensity of your workout to estimate your VO2 max. This is done by measuring the amount of oxygen you consume during exercise and comparing it to the amount of carbon dioxide you expel. During physical activity, the Apple Watch measures your heart rate in beats per minute and compares it to your average resting heart rate. When the intensity of a workout increases, so does the amount of oxygen consumed and expelled. The Apple Watch then compares these two values to estimate your VO2 max.

Accuracy of Cardio Fitness on Apple Watch

The short answer is that the accuracy of cardio fitness on the Apple Watch can vary. While studies have suggested that the Apple Watch’s accuracy is less than 50 percent, this may not be the case for everyone. The Apple Watch tracks heart rate using photoplethysmography, which uses light to track the beats per minute of your heart rate. This technology can be affected by factors such as skin tone, body movements, and other environmental factors. Therefore, it is possible for some individuals to experience more accurate readings than others. It is also important to note that even if the readings may not always be 100 percent accurate, they can still provde valuable insights into your overall health and activity levels.

It can estimate your VO2 max during brisk hikes, walks, or runs outdoors with persistent heart rate measurement. The estimated VO2 max score can give you an indication of your cardio fitness level, with 15-30 signifying a low fitness level, 30-38 being average to above average, and anythig over 40 as high. With regular use of the Workouts app and tracking of your heart rate response to physical activity, you can use Apple Watch to stay motivated and improve your overall fitness level.
