About

This data field estimates your VO2max from a treadmill running test. This is particularly useful in snowy, wintery climates where it is difficult to run outdoors. You must be able to run a steady pace of 7 miles per hour (11.3 km/hour) or faster to use this app. # Features * Displays incline in degrees or percent during the test. * Displays estimated VO2max at the end of the test. * Selectable between graded or fixed distance method # Instructions (graded method): For the fixed distance method, see: https://ko-fi.com/post/Treadmill-VO2max-Fixed-Distance-Method-Instruction-N4N6UBH71 1. Add the data field to your treadmill activity. 2. Set the treadmill to 0 degree incline, and speed to 11.3km/h (7mph). 3. Start the activity on your Garmin watch. and warm up for 10 minutes. 4. At the 11 minute mark and every minute thereafter, the watch will vibrate and the new incline setting will be shown on the data field, set the treadmill incline to this value. (The inclination increases 2 degrees at the 11, 12, 13, 14 and 15 minute mark, and by 1 degree at the 16 minute mark and every minute thereafter.) 5. When you can no longer continue, press STOP on your Garmin watch and stop the treadmill. 6. Switch back to the activity screen (left swipe on touchscreen devices) to see the measured VO2max. 7. After this, you can save the activity. # FULL Version Features * VO2max results will be written to the FIT file for viewing with the activity in Garmin Connect (including heart rate at the end of the test) * Option to measure heart rate recovery (HRR) at the end of the test. Instructions for this option: https://ko-fi.com/post/Measure-Heart-Rate-Recovery-with-the-Treadmill-VO2-D1D7RDTML In Garmin Connect, the value for Heart Rate Recovery will be shown with the activity summary. For example, a Heart Rate Recovery value of 25bpm means that your heart rate dropped 25bpm after you stopped running. As your fitness improves over time, this value should increase. * Determines VO2max adjustment for altitude and saves this for viewing with the activity in Garmin Connect. For example, if the VO2max adjustment value is 5%, then the reported VO2max should be further multiplied by 1.05 to estimate your VO2max at sea level. * Sends the VO2max result to the FitRate app for historical trend graph and fitness ranking.
