Abstract: The present work is part of a complex study of the health problems concerning the training of schoolchildren from the musical school--Sofia in specialty violin and piano. In order to examine the changes in the activity of the sympathetic-adrenal system for tracing the concentrations of sodium, potassium and index sodium/potassium in saliva of schoolchildren from the musical school during the general education program and also during individual training. The changes established during the experiment show the dynamics in the functional state of the sympathetic-adrenal system. We have to mention, that during the individual training an increased activity of the adrenal is observed, in connection with the emotional adjustment and emotional expenditure of schoolchildren.
