There has been exponential growth in international research studies focusing on Sedentary Behaviour (SB) since 2008. Whilst still emerging, the research now provides compelling evidence that there is a multitude of serious health risks connected to "prolonged" and "excessive" sitting. The index below details research listed both in the Expert Statement (Blue) and supplementary research studies (Red).
