What the research shows
An observational cohort study followed 147,414 adults aged 40 to 74 who took part in NAKO and UK Biobank. Physical activity was measured with devices, and the intensity of that activity was linked to the risk of death. The publication that shared this work claims that 12 minutes per week of vigorous activity is equivalent to 150 minutes of moderate activity in relation to mortality. This comparison appears as the publisher's claim and should be read that way.
Observational studies identify associations but do not prove cause and effect. People who move with more intensity may differ in income, prior health, habits and other factors that also influence mortality. The finding therefore shows a link between intensity and risk of death, without proving that vigorous activity alone reduces mortality. Minute-based equivalences should be treated with caution until other studies and reviews confirm them.
What it means
The finding suggests that the intensity of physical activity is associated with the risk of death in this group of adults. It is not yet clear whether the relationship is causal, or whether the minute-based equivalence applies to other populations, ages or health levels.
