Abstract

Obesity has become a pandemic, with more than a billion people affected worldwide. During the past two decades, the prevalence of obesity in children has risen greatly throughout the entire world. This is especially alarming in youth where the new prevalence is above predicted trends. This study was aimed at providing an intervention program for adolescents in the category of overweight/obese in accordance with physical activity (PA) guidelines. The total duration of the project was 8 weeks. The purpose of the study was to assess the effects of the intervention and promote lifelong participation in physical activities. The research sample was made up of high school students chosen in accordance with selected criteria of BMI between 25 >/= 35.5 (n=27). Data was collected from the participants through the use of questionnaires, internet, and pedometers, as well as objective measurements of height, fat and BMI using the Tanita Body Composition Analyzer. Results showed that there was no reduction in BMI. There was also an increase in the amount of vigorous activity and number of steps throughout the intervention. According to Frömel and Bauman, the logical significance of 240 MET minutes per week was seen in their study, whereas in this study the author noticed a four times greater increase with 957 MET minutes per week, and logical significance in all areas. In conclusion it was noted that increased activity reduces a sedentary lifestyle, while it improved social, mental and health status. In addition, the data indicate that sedentary behaviors are strongly related to overweight/obesity in adolescents. It also demonstrates that the type of model implemented with the intervention must reflect a holistic role and activities must critically reflect the interest and preferences of the participants, so that motivation to proceed is strong and conditions for adherence could be set up.
