Physical Activity - The Lancet (UK)

As London counts down the final days before the beginning of the 2012 Olympic Games, The Lancet publishes a Series on physical activity, including a new analysis that quantifies the global impact of physical inactivity on the world's major non-communicable diseases. The Series will also review current levels of physical activity and trends worldwide, why some people are active and why some are not, evidence-based strategies for effective physical activity promotion, and how a multi-sector and systems-wide approach that goes way beyond health will be critical to increase population-levels of activity worldwide
