The post-communist bloc countries (e.g. the Czech Republic) appear to have a tendency to replicate the “negative” health trends that had been previously witnessed in economically developed Western countries: a decrease in PA and an increase of overweight and obesity(Branca, Nikogosian, Lobstein, & World Health Organization, 2007). Indeed, Central and Eastern European countries could learn from such “negative” Western European and global experiences(Knai, Suhrcke, & Lobstein, 2007). The adolescent population represents one of the most physically active subpopulations(Le Masurier et al., 2008). Branca, F., Nikogosian, H., Lobstein, T., & World Health Organization (Eds.). (2007).
