Introduction: Current lifestyles have led to an increase in sedentary activities and a decrease in physical activity, which can lead to a worsening of the present and future health of children. Aims: This study sought to describe the lifestyle and physical activity habits of schoolchildren in a city in northern Spain and to analyse the relationships between these habits and body composition, physical fitness and certain socio-demographic factors. Methods: The study was conducted on a representative sample of 329 sixth grade elementary school students (aged 11-12) from 31 schools in Logroño (La Rioja). Socio- demographic data, anthropometric data, blood pressure, development level, physical fitness and lifestyle habits and physical activity were recorded. Results: The male students who performed extracurricular sports activities and those at earlier stages of development reported higher levels of physical activity. Direct correlations between physical exercise and fitness were detected, especially with respect to aerobic capacity (r = 0.38), and inverse correlations with hours in front of a screen (r = -0.18), but not with body composition. Conclusions: Given the relationships between levels of physical activity and fitness, strategies to promote physical exercise should be encouraged in order to improve the health of young people. Interventions should focus on promoting access to extracurricular sports activities, reducing sedentary habits and increasing the level of physical exercise in girls. [ABSTRACT FROM AUTHOR]

Introduction: The overnutrition is a constant on developing countries; Chile is not an exception because it has a marked tendency to overweight and obesity in schoolchildren. The muscular strength has been associated with cardiovascular and metabolic health status in scholars. Effective interventions using games are needed to improve the nutritional status and physical fitness in school children. Objective: To assess the intervention effectiveness based on games played at school time to improve the nutritional status and physical fitness in schoolchildren. Method: 156 students aged between 7 to 15 years, attending to two public schools with full school day, to which a pilot program was applied. This pilot program was based on dynamic recreational games during 45 minutes from monday to friday for 3 months in the largest playtime of the school day. Results: At the end of the intervention, we observed a significant modification on children nutritional status, which highlights an increase in the number of children that reached the normal nutritional status (p < 0.001). We also observed a significant number of obese children who reached overweight nutritional status (p < 0.001). We also observed a decrease of leg muscular strength at the end of the study. Conclusions: We found a positive effect of a program based on dynamic recreational games in the largest school playtime, improving nutritional status. However, we didn't observed modifications in the muscular strength. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this systematic review was to assess physical activity promotion programs in school children from 6 to 12 years old. Methods: Randomized and non-randomized controlled trials of physical activity studies with an intervention period equal to or more than 12 months, published in the databases of MEDLINE/PubMed, SciELO, EBSCO and SPORTDiscus through may 2010 were searched. Results: Seven studies were analyzed. Overall, the study design, the follow-up periods, the ethnic characteristics of the population, and the instruments used to evaluate the interventions were heterogeneous. The outcomes showed moderate impact of intervention programs to increase the physical activity in children and adolescents. In two of the studies an increase in physical activity was observed and in five of the studies no significant difference in the physical activity assessed with accelerometers and pedometers was observed. Conclusion: Five out of seven studies did not show statistical differences in cpm, including the longest experimental study. These results suggest the need to design studies including modifications in different environments. [ABSTRACT FROM AUTHOR]
