Mixed

Vigorous physical activity (≥6 METs) is independently associated with a reduced risk of coronary heart disease, whereas the benefits of moderate and light activities are less clear or non-significant in multivariate models.

While any activity is better than none, incorporating vigorous exercise (like jogging, swimming laps, or sports) provides the strongest protection against heart disease. If you cannot do vigorous exercise, consistent moderate activity (like brisk walking) still offers significant benefits, though perhaps slightly less than vigorous efforts.

GoodQualifiesMEDIUM confidence
When we considered the independent effects of specific physical activity components, only total sports or recreational activities (P for trend=0.042) and vigorous activities (P for trend=0.02) were inversely associated with the risk of CHD.

Why this rating

Same cohort strength, but the finding regarding moderate activity is described as 'possible U-shaped' and 'nonsignificant inverse associations' in multivariate models, suggesting measurement imprecision.
