Hi!

I have collected using "breath - by breath" method the oxygen uptake during treadmill running at different running speeds.

What is the best way to filtrate/average the data from Vo2 measurements in order to present as Vo2/speed running ratio to show running economy?

During 3 - minute running stage  I have around 56 different values of oxygen uptake (raw data of breath by breath). Should I calculate arithmetic average from all of these raw 56 results? Or maybe its good idea to average the data to 5 - seconds sections  first and after that calculate the arithmetic average?

And present the economy of running as average oxygen uptake at particular speed of the 3 minute stage??

Thanks
