Inactive life and obesity in all age, social, ethnic and economic categories have reached epidemic proportions, above all, in all highly developed countries of the world. Some studies suggest that school and youth sports may be the only answer to the obesity epidemic. The literature on barriers to youth participation in sports and the high dropout rate of the school sports model indicates that a more inclusive approach and a more diverse youth sports offer could be an effective way to attract and retain children in sports programs. Within the school, extracurricular activities and optional sports should complement regular physical education classes, as was the practice before. All children, regardless of their level of physical abilities, talent and mastery of sports skills, should be encouraged to try themselves on their own initiative in a series of different activities that are fun and contribute to long-term engagement and improvement of physical fitness. Specific goals within school programs should achieve the following tasks: Creation of opportunities to participate in school sports sections, or in a different way organized activities in nature; Carrying out activities in an adequate and professionally supervised environment; Cultivating the desire to compete, while at the same time enjoying mutual company, fostering "fair play", respecting teammates and opponents in the game and forming a team spirit; Establish programs and activity models that meet the needs and interests of the majority of students; Improvement of social interaction and reduction of conflicts among students and prevention of peer violence; Providing opportunities for participation on a principle that is available to everyone, without prior selection; Providing students with the opportunity to try different forms of activities, in order to improve their psychophysical development, emotional and social life, to form a healthy lifestyle and to use their free time properly.
