There is a VO2Max measure in my new FR 955. After one run it calculated something.
There is also another VO2Max metric for biking but here it says I have to bike with heartrate sensor and power meter to get something.
What does this mean?
Do I need to attach those expensive power meter pedals or is something else also enough? Thinking about the speed/cadence sensor for 50 Euros. Do I get any power measures from this setup?
