For a fixed total volume of moderate-to-vigorous physical activity (MVPA), increasing the proportion of vigorous physical activity (VPA) to total MVPA is associated with significantly lower all-cause mortality.
If you currently do 150 minutes of moderate exercise (like brisk walking) per week, try replacing half of that time with vigorous exercise (like running or fast cycling) while keeping the total time at 150 minutes. This shift is associated with a 17% lower risk of death compared to doing only moderate exercise, according to this large study.
This study suggests that, for the same volume of MVPA, a higher proportion of VPA to total physical activity was associated with lower all-cause mortality.
Why this rating
Large national cohort (n=403,681), long follow-up, adjusted for major confounders, but relies on self-reported activity.
