Validation data - Minute ventilation as a function of exercise intensity.

 

Minute ventilation as a function of exercise intensity is an important checkpoint. The benchmark data set uses composite data from a variety of reliable human studies (shown below).

 

 

The table below shows the elements used to display minute ventilation in numerical and graphical formats.

 

QHP’s current response in this validation test (10 minutes of exercise bike) is tabulated below.

Note that the metaboreflex has not yet been converted to XML, so the validation values are currently less than the benchmark values, particularly at higher workloads.
