Workers can benefit from physical activity "of any intensity to mitigate the mortality risks" from prolonged sitting, according to US researchers.
Academics led by Dr Keith Diaz, professor in behavioural medicine at Columbia University, writing in the American Journal of Epidemiology, state that "little is known concerning the type of activity that should be substituted for sedentary time".
However, they write that after conducting tests, their results show that there were benefits in "replacing total sedentary time with" light-intensity physical activity and moderate to vigorous physical activity rather than varying the length of sedentary periods.
These findings suggest "short sedentary bouts still carry mortality risk and are not a healthful alternative to prolonged sedentary bouts", say the researchers.
Instead, physical activity of any intensity is needed to mitigate the mortality risks incurred by sedentary time.
