Researchers have suggested that physical education curricula can be highly effective in increasing physical activity levels at school (Sallis & Owen, 1999). The purpose of this study was to investigate the impact of various curriculum models on physical activity. Total steps were measured on 1,111 subjects and three curriculum models were studied (Fitness, Game/Sport, Skill Themes). Among the curriculum models and across all grade levels, the Game/Sport Model had the most steps (p less than 0.01; M = 2,013), followed by the Skill Themes (M = 1,750), and finally the Fitness Model (M = 1,716). The Fitness Model doesn't guarantee higher activity. Rather, the teacher should strive to create and implement lessons that provide increased time for movement or activity for all children.
