Association football is characterized with a complex demonstration of motor activity. And though it could be stated that men's and women's football game have currently been the subject of serious research and analyses, this has not been the case with junior football. Our research has shown that the existing data is not enough and not convincing enough to shape the conditioning profile of players with reference to age group and duration of play. In order to bring more light on the topic, we concentrated our efforts on determining the speed zones of motor activity during official football matches of 13-14 years old football players. The research involved 28 football players from the junior team of the Levski Football Club, Sofia. The difference from the already existing data lies in the method we have used to acquire our data. It is based on sport-pedagogical tests done on the playing field which provides their objectivity. The data from our tests were processed by means of variation analysis and on these grounds we have established the following speed zones of motor activity for the age group mentioned above: walking <2,3 m/s.; low intensity running 2,4-4,0 m/s.; middle intensity running 4, l -5,0 m/s.; high intensity running 5,1-6,1 m/s. and sprint running >6,2 m/s. Thus specified, they resolve one of the major problems connected with the use of a GPS to provide the necessary photographic material during a football meeting or in training sessions.
