The Claim

Among nonexercising adults, one minute of vigorous incidental physical activity is equivalent to approximately 2.8-3.4 minutes of moderate incidental activity and 34.7-48.5 minutes of light incidental activity for reducing the risk of cardiovascular events and all-cause mortality, as derived from observational data.

In plain English

For people who don't exercise, a single minute of hard activity (like running up stairs) does the same good for your heart as about three minutes of medium exercise (like brisk walking) or about forty minutes of easy exercise (like strolling). So a tiny bit of intense effort gives you the same heart benefit as a lot of easier activity.

See the scientific wording

One minute of vigorous incidental physical activity is equivalent to approximately 2.8-3.4 minutes of moderate incidental activity and 34.7-48.5 minutes of light incidental activity for reducing cardiovascular events and mortality, based on observational data from nonexercising adults.

Why this might work

When you do short bursts of hard exercise, your heart works much harder per minute than when you do easy exercise. This harder work creates more 'stretching' on the inside of your blood vessels, which signals them to stay healthy and flexible. Over time, a few minutes of hard exercise can give your blood vessels the same health benefits as much longer sessions of easy exercise, because the hard exercise delivers a bigger 'dose' of benefit in a shorter time.

  1. Study: Dose Response of Incidental Physical Activity Against Cardiovascular Events and Mortality

    The study found that one minute of very hard incidental activity gives the same heart benefit as about three minutes of moderate activity or about 40 minutes of light activity, so intense activity is more time-efficient for heart health.
