The appropriate design of load and demands in the athletic training of children and adolescents has been a recurrent problem - in particular with regard to the long-term performance development within elite sport. The biological conditions of load tolerance are of vital importance in this age group. A population of children exposed to high loads was studied to compare epidemiological data and individual states in order to identify indicators of load tolerance. These analyses revealed the following indicators: factors of biological development (height velocity, maturity), nutritional state, constitutional factors, factors related to adaptation, factors of insufficient general load compensation. The diagnosis and the observation of these indicators of load tolerance are the essential conditions for a preventive effect of athletic activity and for successful long-term performance development in elite sport.
