Target load calculation if target load is reached - Standard calculation

This calculation is the default calculation from custo diagnostic 4.0.4.

For the calculation of the target load if target load is reached the following formula is used:

if Age <= 30:

  male:     Target Load = 3 * Weight

  female:  Target Load = 2.5 * Weight

if Age > 30:

  male:     Target Load = 3 * Weight * ((130 - Age)/100)

  female:  Target Load = 2.5 * Weight * ((130 - Age)/100)

Target load calculation if target load is reached - Calculation according Prof. Froelicher

This calculation is available from custo diagnostic 4.0.4 as Option "according to Prof. Froelicher".

For the calculation of the target load if target load is reached the following formula is used:

  male:     6.773 + (136.141 * SurfaceArea) - (0.064 * Age) - (0.916 * SurfaceArea* Age)

  female:  3.933 + (86.641 * SurfaceArea) -  (0.015 * Age) - (0.346 * SurfaceArea* Age)

Hint: The Surface Area is calculated according a formula by DuBois & DuBois: KOF = 0,007184 x Height [cm]^0,725 x Weight [kg] ^0,425
