BMC has recently launched a new journal entitled Journal of Activity, Sedentary and Sleep Behaviors(JASSB). The journal is inspired by the recognition of two important pillars of the 24-hour well-being, physical activity and sleep. Led by Professor Corneel Vandelanotte as the Editor-in-Chief, the journal uniquely covers these two broad subject areas and embraces the development of knowledge and research that adopts a 24-hour approach when examining or manipulating physical activity, sedentary and sleep behaviors and their effect on health. The journal’s full aims and scope can be found here. The journal is also equipped with a strong editorial board that will support the manuscript evaluating process by providing timely and quality reviews.
