Adherence
Accumulating 30–40 minutes of moderate-to-vigorous physical activity (MVPA) per day attenuates the increased risk of all-cause mortality associated with high sedentary time in middle-aged and older adults.
If you sit for long periods, you can significantly lower your mortality risk by getting 30-40 minutes of moderate-to-vigorous activity (like brisk walking or jogging) each day. You do not need to exercise for an hour to see these benefits. This threshold is lower than previously thought based on self-reported data.
About 30–40 min of MVPA per day attenuate the association between sedentary time and risk of death, which is lower than previous estimates from self- reported data.
