ABSTRACT The obesity epidemic is a global trend and is of particular concern in children. Recent reports have highlighted the severity of obesity in children by suggesting: "today's generation of children will be the first for over a century for whom life expectancy falls." This review assesses the evidence that identifies the important role of physical activity in the growth, development and physical health of young people, owing to its numerous physical and psychological health benefits. Key issues, such as "does a sedentary lifestyle automatically lead to obesity" and "are levels of physical activity in today's children less than physical activity levels in children from previous generations?", are also discussed.Today's environment enforces an inactive lifestyle that is likely to contribute to a positive energy balance and childhood obesity. Whether a child or adolescent, the evidence is conclusive that physical activity is conducive to a healthy lifestyle and prevention of disease. Habitual physical activity established during the early years may provide the greatest likelihood of impact on mortality and longevity. It is evident that environmental factors need to change if physical activity strategies are to have a significant impact on increasing habitual physical activity levels in children and adolescents. There is also a need for more evidence-based physical activity guidelines for children of all ages. Efforts should be concentrated on facilitating an active lifestyle for children in an attempt to put a stop to the increasing prevalence of obese children.

    ABSTRACT: The desire of most people today is directed towards health, vitality, quality and long life. Results of some studies show that people who exercise regularly, with properly organized and individual physical activity, are less prone to various kinds of diseases of today, primarily cardiovascular and psychosomatic. Physical activity and sport, in the process of educating the youth should be an important factor in building, maintaining and improving the bio-psycho-social components of the student population.Noting the relevant issues for further functioning and development of university sport in Serbia, where special attention is drawn towards determinism in creating conditions for meeting the needs and interests of students for physical activity and health promotion, has been identified the need for establishing the basic parameters for the proper organization and direction of university sport. In this context, it highlights the position of the female student population for who are linked very negative indicators of their involvement in physical and sports activities, bo th at the University and in everyday life. Empirical research conducted at the University EDUCONS was aimed at determination of motivational drivers of studentsfor inclusion in the potential programs of physical exercise at the University. In a sample of 170 students, using a modified Campbell motivation questionnaire (Campbell et al, 2001) was detected the structure of motivation for physical training at the University, through the nine motives, in the manifest and latent space.

    ABSTRACT: BACKGROUND The purpose of this research was to examine the impact of school-related variables on the physical activity (PA) levels of early adolescent African American, Latino, and White girls.METHODS Data were collected from 353 African American (N = 123), Latino (N = 118), and White (N = 112) girls. Physical activity levels included a PA latent factor and minutes per day of moderate-to-vigorous physical activity (MVPA). School variables included hours of physical education (PE), PE enjoyment, school physical environment, recess activity, and active transport to/from school. Multiple-group structural equation modeling examined relations between school variables and PA across ethnic groups.RESULTSHours of PE were positively related to higher PA factor scores. Active transport was related to higher PA factor scores for White girls only, and to greater MVPA for African American girls only. Hours of PE were related to PE enjoyment and the school physical environment for some ethnic groups. Physical education enjoyment was related to more recess activity among African American and Latino girls, and PE enjoyment was associated with more active transport to school for all girls.CONCLUSIONS Physical education participation and active transport significantly contribute to girls' levels of PA, with differences across ethnic groups.

    ABSTRACT: Introduction: A number of randomized trial studies and longitudinal researches emphasize that despite problems in social adjustment and cognitive damages, children with cancer demonstrate good emotional adjustment. Method: Most of the research findings in this area are obtained using objective tools such as questionnaires. "Vitality of children", as a drawing tool, was used as basis to draw a comparison between children with cancer and healthy children in this study. Accordingly, 112 children with cancer (5 girls and 57 boys aged 3 to 12 years) and 123 healthy children (77 girls and 46 boys aged 3 to 12 years) participated in the study. Results: Findings showed that the vitality of the two groups differed significantly. Perhaps, children with cancer repress negative emotions and avoid expressing their feelings. Conclusion: Making use of such tools that indirectly examine the emotional experience of children with cancer would be beneficial. Neglecting this issue can cause children with cancer to be deprived of receiving supportive counselling.
