Summary
Theconnectionofthephysicaldevelopmentwiththefunctionalmobilityandthepowerofthemainnervousprocesseswasinvestigated.Thepropertyofthenervousprocessesfunctionalmobility(NPFM)wasdeterminedaccordingtothemaximumspeedunmistakendifferentiationofthepositiveandnegativestimulus.Thenervousprocessespower(NPP)wasdefinedaccordingtothegeneralamountofthepresentedandprocessedinformationforadefiniteperiod.Theanthropometricindexesaswellasthecardiorespirationsystemparametersinthestateofrestandafterthefunctionaltestwereusedforthedefinitionofthephysicaldevelopmentcoefficient(PDC).Theindexesofthephysicaldevelopmentandnervoussystemindividual-typologicalpropertiesamongtheyoungstersweredeterminedtoincreasegraduallyandirregular.Thecomplexinterrelationswerediscoveredintheagechangedynamicsofthehighernervousactivitytypologicalpropertiesandphysicaldevelopmentindexes.Theageperiods(7-8,13-14,15-16)whentherateofthephysicalandneurodynamicdevelopmentbeingconformedweredefined.Physicaldevelopmentdelaywasdiscoveredonthebackgroundofincreasingformationratesoftheneurodynamicfunctionsattheotherageperiods(8-13,14-15).
