Preventive Medicine offers several articles on physical exercise interventions, including a UK study on the contribution of active travel to physical activity levels in schoolchildren, the effect of a school-based active commuting intervention and a population-based RCT of a pedometer combined with an intervention toolkit for people with low levels of fitness or physical activity. A systematic review in the American Journal of Preventive Medicine assesses the state of knowledge on adult sedentary behaviour.
