In my thesis I deal with the problematics of physical ability at the Police of the Czech republic, specifially when it comes to the policemen ranked in the first line patrol in the south Moravian region. In the theoretical part I explain basic information about the police, what means "first line patrol" and the possibilities of testing the physical ability at the Police of the Czech republic and in the countries bordering with the Czech republic. In the practical part I compare the collected data of the performances of the policemen ranked in the first line patrol in the course of five years, among the policemen studuying the basic specialized training and with the norms of the high school age young people.
