Adherence
Replacing sitting time with physical activity eliminates the increased mortality risk associated with high sedentary behavior, particularly when achieving ≥420 minutes of moderate-to-vigorous PA per week.
If you have a sedentary job, do not rely on short workouts. Aim for at least 420 minutes of moderate-to-vigorous activity per week (e.g., brisk walking, running) to cancel out the risks of sitting. This is a significant amount of time, so integrate activity into your day through commuting, breaks, and leisure.
GoodQualifiesHIGH confidence
Negative effects of longer sitting times were almost eliminated at increased PA, especially in the highly active group (≥420 min of moderate-to-vigorous PA per week).
Why this rating
Based on large prospective follow-up study (n=149,077).
