Name: Power Derived MET (Beta)
Author: Trudelta

This data field displays the metabolic equivalent of an activity, METs, derived from power measurements from a cycling or rowing power meter.  Therefore, this measurement will be faster responding to changes in physical exertion than heart rate derived METs.  One MET is 1 kcal/kg/h which is approximately the calorie burn rate at rest. 
For more information on MET, see https://metscalculator.com/

Although VO2max measurement is more desirable for measuring cardiovascular fitness, Garmin watches only provide this for running and cycling.  For people that do neither of these activities, METs is an alternative way to gauge cardiovascular fitness.

You should be capable of exercise at a level of at least 5 METs for an independent lifestyle and a higher survival rate. Higher than 8 METs is more desirable because at 8 METs risk factor for death from major causes is reduced in half compared to at 5 METs. See https://www.nejm.org/doi/full/10.1056/NEJMoa011858 
The maximum METs recording feature is useful for this purpose.

# Features
* Display real-time measurement, average over the entire activity duration (indicated as Avg. MET), or current lap average MET (indicated as Lap MET)
NOTE: You need to enter your estimated Metabolic efficiency in the settings, which is the percentage of whole-body metabolic energy expended that is actually converted to external mechanical work. This is usually between 20-25%.
* Adjustable calibration scaling factor

# Full Version Features
* Saves MET data to the activity session record for graph display in the Garmin Connect app
* Saves max & average MET over the activity duration and total MET·hr expended to the FIT file for display in the Garmin Connect app activity summary
* Saves Lap MET values to the FIT file for display in the Garmin Connect app lap data
* Option to display moving average MET over a custom defined duration (2-60 seconds)
* Determines heart rate recovery at the end of the activity and saves this for viewing in Garmin Connect. To use this, enable the option to measure HR recovery in the settings before starting your activity. Press STOP as usual at the end of your exercise. Rest. At the end of the 2 minutes, the watch will vibrate, indicating that the heart rate recovery has been measured. Now save the activity. View the results in Garmin Connect. For example, a heart rate recovery value of 25 means that your heart rate dropped 25bpm after 2 minutes. This value should increase as your fitness level improves.
