What is VO2 max and how does this app measure it?
VO2 max represents the maximum amount of oxygen your body can absorb and utilize during peak physical exertion. This app estimates your VO2 max by utilizing data from outdoor walks or runs tracked with continuous heart-rate monitoring for at least 20 minutes, with the Workout app running and GPS enabled on your Apple Watch.
What kind of performance estimates does the app provide?
The app provides estimates for running and cycling by converting your VO2 max and weight into W/kg and FTP (Functional Threshold Power) values. It also allows you to compare modeled race times and power outputs against your actual HealthKit FTP or power meter data.
