Regardless of how much physical activity someone gets, prolonged sedentary time could negatively impact the health of the heart and blood vessels, finds out Deborah Rohm Young, director of behavioral research at Kaiser Permanente Southern California in the US.
Sedentary behavior may be associated with an increased risk of developing diabetes, cardiovascular disease, impaired insulin sensitivity (linked to diabetes) and an overall higher risk of death from any cause, researchers said.
"There are many important factors we don't understand about sedentary time yet. The types of studies available identify trends but don't prove cause and effect. We don't have information about how much sedentary behavior is bad for health," Young said.
Instead of doping all the exercise into one or two days, the best advice at this time is to 'sit less and move more'. The goal is to encourage more consistent activity, Young said.
However, the researchers found that moderate to vigorous physical activity does not cancel out the impact of sedentary time. Even physically active people who spend a lot of their time being sedentary appear to have increased risk.
Sedentary behaviours include sitting, reclining, or laying down while awake as well as reading, watching television or working on the computer.
