Feature Request: Estimated VO2 Max calculation based on 5-minute Peak Power**
Summary:
I would like to request the addition of an “Estimated VO2 Max” metric derived from an athlete’s 5-minute peak power output.
The Concept:
Recent research (as detailed by Velo/Outside Online) suggests a reliable formula for estimating VO2 Max using relative power (w/kg) from a maximal 5-minute effort. This would allow athletes to track their aerobic capacity trends directly within Intervals.icu based on their power data.
The Formula:
Estimated VO2 Max (mL/kg/min) = 16.6 + (8.87 x 5-minute peak power w/kg)
Proposed Implementation:
- Activity Metric: Add a field in the activity “Power” section that calculates this value if a 5-minute peak power is detected.
- Fitness Trend: Allow this estimated value to be plotted on the Fitness page chart to track aerobic changes over time alongside FTP and weight.
- Custom Field: Alternatively, provide this as a predefined “Custom Field” option for the Activities list.
Rationale:
While lab testing is the gold standard, many cyclists use the 5-minute power test as a key performance indicator. Automating this calculation provides a simple, evidence-based way to monitor cardiorespiratory fitness without the cost of a lab visit.
