Estimation of VO2max from the ratio between HRmax and HRrest: the Heart Rate Ratio Method

What this work gives Aellic

VO2max can be estimated as 15.3 x HRmax / HRrest. Derived in 46 well-trained men aged 21 to 51, so the sample is small, male and fit; for everyone else the ratio gives a rough population-level estimate, labelled as estimated in the app. Aellic applies it only when no device-measured VO2max exists in the last 60 days.
