Energy balance

Reallocating 30 minutes per day of sedentary time to light-intensity physical activity (LIPA) yields beneficial but smaller improvements in triglycerides, insulin, and insulin sensitivity compared to MVPA.

If you cannot do vigorous exercise, replacing 30 minutes of sitting with light activity (like slow walking or household chores) still improves your insulin and triglyceride levels, though not as much as brisk exercise would.

GoodQualifiesMEDIUM confidence
Reallocating 30 minutes/day of SB to LIPA had the following significant beneficial associations with some biomarkers, but to a lesser extent than when reallocating to MVPA: 1.9% lower triglycerides, 2.4% lower insulin, 2.3% lower HOMA-β, and 2.3% higher HOMA-S.

Why this rating

Large sample with objective activity measures, but cross-sectional design limits causality.
