Energy balance

Replacing sitting time with vigorous physical activity (VPA) yields the largest reduction in cardiovascular disease mortality risk, particularly for individuals who sit more than 6 hours per day.

If you sit for more than 6 hours a day, try to replace some of that time with vigorous exercise (like running, fast cycling, or high-intensity interval training). This substitution offers the greatest protection against heart disease-related death. Even replacing sitting with brisk walking helps, but vigorous activity provides the strongest benefit for high sitters.

GoodSupportsHIGH confidence
Replacing sitting with walking and MVPA showed stronger associations among high sitters (>6 sitting h/day) where, for example, the per-hour CVD mortality HR for sitting replaced with vigorous activity was 0.36 (95% confidence interval: 0.17 to 0.74).

Why this rating

Based on isotemporal substitution modeling in a large cohort, providing strong observational evidence for substitution effects.
