![]() If the MET value of a specific activity is 4, it means that you’re burning 4 times as many calories as you would burn while resting. MET is a common measure used to express the energy expenditure and intensity of different physical activities. Oura calculates your daily energy expenditure using METs or Metabolic Equivalents. How Oura Uses METs to Calculate Energy Expenditure On the Oura App for iOS, you have the option to import your workouts from Apple Health, and with Android, you can import workouts from Google Fit. For non-step-based activities that are more difficult to measure (e.g., yoga), manually adding your activities or workouts on the Home tab can improve the accuracy of your Activity Score. To improve the accuracy of your activity tracking, make sure the sensor bumps of your ring are on the palm side of your finger. This system captures most of your daily activities well, however, all accelerometers have more difficulty with activities that involve limited hand movement in one direction (e.g, an elliptical, lifting weights), no hand movement (e.g., cycling), or intense movement that is isolated to your hands (e.g., drumming). The Oura Ring uses a 3D accelerometer for activity tracking which measures how your ring moves up and down, side to side, and back and forth. Many trackers set a different threshold for what counts as "activity" while others categorize all movements as steps. ![]() Other wearables or apps may show different step estimates because they use a different method of categorizing steps. Any non-step movement is still captured in your total activity. Oura is able to identify step patterns within a very small window of time (30 seconds) and with a high level of precision from your finger. The Fitbit has been fairly accurately measuring my walks ever since.The Oura ring registers all your daily movements and their intensities, from light housework to heavy workouts. From the gathered data, Oura’s activity algorithms are fine-tuned to recognize steps from the rest of your daily movement. Both averaged about the same length, so I went into the app settings and changed the default stride length to my measured value. I then repeated the process and calculated the stride length again. I divided the number of steps by 1320 to get the average stride length. I did a test by walking on a marked quarter mile track, and counting the steps. That is why "average" stride length is important. But when you walk outdoors you are constantly walking at slightly different speeds and different stride lengths. A treatdmill is a measured, constant speed in which you get into a rhythm of taking steps. Good point, but remember that the stride length on a treadmill is almost never the same as it is in in natural walking outdoors. I walked farther than fb calculated, which means the fb stride was shorter than my own. What I found is that fitbit was "cheating" me, i.e. Same speed, for long enough that the bars on the graph were all practically the same. When I did a rather scientific determination of stride length, I did it on a treadmill. The walk was done at night (starting 10pm, finishing around 5am), hence the weird times! Kilometers 22 to 28 were between 2:45 and 3:45am. I have added a screenshot of the steps chart from the Fitbit Dashboard. Have I missed something here? I am really struggling to understand why my step length seems to be so high. So 6270 steps in 5690 metres, which gives a step length of 0.9075metres or 90.75cm. Walking kilometers 22.22 to 27.91 of the walk took me one hour, in which time my Fitbit tells me I took 6270 steps. I am not conscious of having an unusually long stride length. From everything I have read online, this step length seems enormous. I am a 5 ft 7 female, in ok but not fantastic fitness. ![]() The issue I am having is that my calculations show a step length of 35.72 inches. I wanted to use this data as I figured over such a large distance, my steps should have been roughly what they would normally be. I tracked the walk using both my Fitbit and RunKeeper on my phone, and have selected a just under 6km segment of the walk where I did not take any breaks to use in my calculations. I did a 20 mile walk in July so I have been using the data from that to try and calculate the stride length. I've been trying to calculate my walking stride length (actually step length, but Fitbit calls it 'stride length') to improve the accuracy of the distances that my Fitbit (Charge HR) shows.
