Adherence
The health effects of reallocating time between behaviors are asymmetric; losing MVPA has a much larger negative impact than gaining MVPA has a positive impact.
Protecting your existing MVPA time is crucial. Losing 10 minutes of vigorous activity has a much larger negative impact on waist circumference than the positive impact of gaining 10 minutes. Prioritize not losing your current activity levels.
GoodQualifiesHIGH confidence
Strikingly, the effects of MVPA replacing another behavior and of MVPA being displaced by another behavior are asymmetric. For example, re-allocating 10 minutes of SB to MVPA was associated with a lower waist circumference by 0.001% but if 10 minutes of MVPA is displaced by SB this was associated with a 0.84% higher waist circumference.
