Replacing sedentary time with vigorous physical activity (VPA) reduces the risk of more types of non-communicable diseases (NCDs) than replacing it with light (LPA) or moderate (MPA) physical activity.
If you sit for more than 6 hours a day, try to replace that time with vigorous activity rather than just light movement. Swapping 1 hour of sitting for 1 hour of vigorous activity (like running or fast cycling) is associated with a significantly lower risk of multiple chronic diseases compared to swapping it for light or moderate activity. While achieving 1 hour of VPA daily is challenging, even partial substitutions offer substantial health protection.
Replacing sedentary time with equivalent VPA than LPA and MPA could be associated with risk reductions of more types of NCDs.
Why this rating
Large prospective cohort (n=360,047), but relies on self-reported data and observational design, preventing strict causal inference.
