During the initial phase of the Erasmus+ project European Fitness Monitoring System (EUFITMOS), a systematic review was performed, to analyse the international evolution of fitness with its distributional changes in the performance on tests of physical fitness among school-aged children and adolescents.

Physical fitness is a state of being that reflects a person’s ability to perform specific exercises or functions and is closely related to present and future health outcomes.
In a school context, tests are being used as institutional fitness assessment tools, educational tools to teach youth and their families about the importance of physical fitness, and as communication tools to guide individuals on attainable goals for maintaining fitness and health.
