Aim of this thesis was to evaluate basic fitness and physical development among 12-15 year-old boys and girls - members of the Czech Athletics Federation Sport Centers (CAF SCs) - in the year 2012. In many tests, performance of SCs members in 2012 was worse than of SCs members in 2011.
From comparison of physical parameters of athletes with average population, we can conclude that SCs members are taller, more muscular and have more favourable values of BMI index.
