Implementation of the computational training software. Once linked to http://cctrainer.ifc.cnr.it., after filling the "insert case sheet" and clicking on the "rest and stress data calculator" button, the calculation results sheet opens. Calculation algorithms are shown in column 2 and software calculated results appear in the third "rest" and in the fourth "peak "column". In the sixth column the trainer will find % rest-peak change values. Each definition/abbreviation can be expanded to a full description simply pointing the mouse cursor.
