Calculate the "Mean Value"
1. Make active the graph window (any Y vs any X graph).
2. Right-click and select
Fitting.
3. Choose Mean value in the type combo box
4. Select the first point ( X1 ) moving the mouse on the desired place in the graph
pressing the Left key or using the + and – keys.
5. Select the second point ( X2 ) moving the mouse on the desired place in the graph
pressing the Right key or using the + and – keys.
6. Press OK to confirm.
Note: The results of the O2 Fittings function are not stored therefore, in order to keep

Oxygen Kinetic
This function is available only if the active window is a VO2 vs time graph and it has a
sense only with Constant Load Exercise Tests.
The aim of this function is to find the dynamic response of the rising and falling edges
of the VO2 together with the Oxygen Deficit and Oxygen Debt.
Run the O2 Kinetic function
1. Make active a VO
2
vs Time graph window.
2. Press the right key of the mouse and select O2 Kinetic .
3. Select the beginning of the exercise phase ( t1 ) moving the mouse on the desired
place in the graph pressing the Left key or using the + and - keys.
4. Select the beginning of the exercise phase ( t2 ) moving the mouse on the desired
place in the graph pressing the Right key or using the + and - keys.
5. Enter (if necessary) the initial values for A, B and Tau (these are the values from
which the iterative algorithm starts in order to reach the best values; the closer are
the initial coefficients to the best ones the higher is the possibility to reach the best
fit) and press
OK . You can lock data checking the relative field
