摘要：Over the last twenty years, rapid changes in the lifestyles of children and adolescents have been observed worldwide. Studies of secular changes show that changes in the lifestyles of children and adolescents in developed countries are manifested in an increased amount of subcutaneous fat, in a higher proportion of overweight population and in deterioration of their motor performance, particularly endurance and strength. Poor physical fitness of children and youth is associated with many preventable diseases and poses a serious current and future public health problem. Regular and quality physical activity (PA) during childhood can lead to improvements in numerous physiological and morphological variables in children and youth. Therefore, school-based PA interventions are important in improvements of PA level of children and their outcomes. One of PA intervention programmes started in Slovenia in September 2014. Recently, this intervention has been offered to schoolchildren between the ages of 10 and 12. Studies of physical development of children aged 10-12 have revealed that the proportion of overweight and obese children in Slovenia has been increasing, particularly in this age group, and that physical fitness of these children has been decreasing even more than amongst adolescent youth. Such school-based PA intervention can significantly influence the physical fitness of children. Therefore, the concept of design of new PA intervention programme, grounded on research-based data, is presented to show that the planning of such intervention programme should be based on research evidence and experience, should include modern approaches to the programme content and its implementation, should be organizationally well designed and should also be implemented by professional, competent teachers.
